What are cooling blankets? Can they really help me sleep?

<p><em><a href="https://theconversation.com/profiles/linda-grosser-1461631">Linda Grosser</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a> and <a href="https://theconversation.com/profiles/luana-main-2270550">Luana Main</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a></em></p> <p>You wake up exhausted from yet another hot night of tossing and turning, with very little sleep.</p> <p>So you might be tempted to buy a “cooling blanket” after reading rave reviews on social media. Or you might have read online articles with <a href="https://www.news.com.au/checkout/home-and-garden/bedroom/bedding/best-cooling-blankets/news-story/118ce05eba1e7d5cdff3aeadae5ae940">taglines such as</a>:</p> <blockquote> <p>Stop waking up in a puddle of sweat with our roundup of the best cooling blankets – including a top-rated option from Amazon that ‘actually works’.</p> </blockquote> <p>But what are cooling blankets? And can they help you get a restful night?</p> <h2>We know a cooler bedroom is best</h2> <p>First, let’s look at why a cooler environment helps us sleep better at night.</p> <p>Our body’s internal temperature has a <a href="https://www.sleepfoundation.org/circadian-rhythm">circadian rhythm</a>, meaning it fluctuates throughout the day. A couple of hours before bed, it drops about <a href="https://www.sciencedirect.com/science/article/pii/S1087079203000236">0.31°C</a> to help you fall asleep. It will drop about <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC7323637/">another 2°C</a> across the night to help you stay asleep.</p> <p>During sleep, your internal temperature and skin work together to achieve a balance between losing and producing heat. Your skin has sensors that pick-up changes in the environment around you. If it gets too warm, these sensors let your body know, which may cause you to kick-off blankets or bed clothes and wake more often leading to poorer sleep quality.</p> <p><a href="https://www.thensf.org/what-is-sleep-quality/">Sleep quality</a> is an important component of sleep health ensuring you get the physical, mental and emotional benefits that come from a good night’s sleep.</p> <p>The <a href="https://www.sciencedirect.com/science/article/pii/S0360132318300325">ideal temperature</a> for sleep varies depending on the season and type of bedding you have but falls between 17°C and 28°C. Keeping your sleeping environment within this range will help you to get the best night’s rest.</p> <h2>So what are cooling blankets?</h2> <p>Cooling blankets are designed to help regulate your body temperature while you sleep.</p> <p>Different technologies and materials are used in their design and construction.</p> <p>We’re not talking about <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC2206487/">hospital-grade</a> cooling blankets that are used to reduce fever and prevent injury to the nervous system. These use gel pads with circulating water, or air-cooling systems, connected to automatic thermostats to monitor someone’s temperature.</p> <p>Instead, the type of consumer-grade cooling blankets you might see advertised use a blend of lightweight, breathable materials that draw moisture away from the skin to help you stay cool and dry through the night. They look like regular blankets.</p> <p>Common materials include cotton, bamboo, silk or the fibre <a href="https://goodonyou.eco/how-ethical-is-tencel/">Lyocell</a>, all of which absorb moisture.</p> <p>Manufacturers typically use a <a href="https://www.sleepfoundation.org/best-sheets/best-thread-count-for-sheets">thread count</a> of <a href="https://www.trustsleep.com/how-do-cooling-blankets-work/">300-500</a>, creating air pockets that enhance airflow and moisture evaporation.</p> <p>Some blankets feature a <a href="https://getrest.com.au/blogs/all/unveiling-the-secrets-of-q-max-the-key-to-a-perfect-nights-sleep">Q-Max rating</a>, which indicates how cool the fabric feels against your skin. The higher the value, the cooler the fabric feels.</p> <p>Others feature <a href="https://www.trustsleep.com/how-do-cooling-blankets-work/">phase change materials</a>. These materials were developed by <a href="https://spinoff.nasa.gov/Spinoff2009/ch_4.html">NASA</a> for space suits to keep astronauts comfortable during a spacewalk where temperatures are from roughly <a href="https://www.nasa.gov/humans-in-space/spacewalk-spacesuit-basics/">-157°C to 121°C</a>. Phase change materials in cooling blankets absorb and hold heat producing a cooling effect.</p> <h2>Do they work?</h2> <p>If you believe online reviews, yes, cooling blankets can cool you down and help you sleep better in warmer weather or if you get too hot using normal sheets and blankets.</p> <p>However, there is little scientific research to see if these consumer-grade products work.</p> <p>In a 2021 <a href="https://www.mdpi.com/2071-1050/13/16/9099">study</a> exploring sleep quality, 20 participants slept for three nights under two different conditions.</p> <p>First, they slept with regular bed sheets in an air-conditioned room with the temperature set to their preference. Then, they used cooling bed sheets in an air-conditioned room where the temperature was set 3°C higher than their preference.</p> <p>Participants reported good sleep quality in both conditions but preferred the warmer room with its cooling sheets.</p> <p>This may suggest the use of cooling bedding may help provide a more comfortable night’s sleep.</p> <p>But everyone’s cooling needs varies depending on things like age, health, body temperature, the space you sleep in, and personal preferences.</p> <p>So while these products may work for some people who may be motivated to leave a good review, they may not necessarily work for you.</p> <h2>Are they worth it?</h2> <p>There’s a wide variety of cooling blankets available at different prices to suit various budgets. Positive customer reviews might encourage a purchase, especially for individuals experiencing disrupted sleep at night due to heat.</p> <p>Yet, these cooling blankets have limited scientific research to show they work and to say if they’re worth it. So it’s up to you.</p> <h2>What else can I do if I’m a hot sleeper?</h2> <p>If a cooling blanket isn’t for you, there are other things you can do to stay cool at night, such as:</p> <ul> <li> <p>using air conditioning or a fan</p> </li> <li> <p>placing a damp towel under or over you</p> </li> <li> <p>wearing lightweight or minimal sleepwear and avoiding thick or synthetic fabrics, such as nylon, that can trap heat</p> </li> <li> <p>if you usually share a bed, on hot nights, consider sleeping by yourself to avoid excess body heat from your partner.</p> </li> </ul> <p>On a final note, if you often struggle with hot, disturbed sleep, you can check in with your health-care provider. They can see if there is a medical explanation for your disturbed sleep and advise what to try next.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/244158/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/linda-grosser-1461631">Linda Grosser</a>, Research Associate, Behaviour-Brain-Body Research Centre, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a> and <a href="https://theconversation.com/profiles/luana-main-2270550">Luana Main</a>, Associate Professor in Applied Sport Science, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

A <a href="https://jamanetwork.com/journals/jamaophthalmology/fullarticle/2522190">study of 29 cars</a> found a range from 4% to almost 56% of UVA passed through the side and rear windows.</p> <p>The UVA protection was not related to the car’s age or cost, but to <a href="https://www.sciencedirect.com/science/article/pii/S0190962205046244?casa_token=qxVQnQ_mFjEAAAAA:5n6QVYBb22gfsWNLxfxbNtsibJ1JXl_C7RtRhsaQLFVkRocFgoWiI4BnNyMGO35EnyIsLNhFK90">the type</a> of glass, its colour and whether it has been tinted or coated in a protective film. Grey or bronze coloured glass, and window tinting, all increase UVA protection. <a href="https://academic.oup.com/tropej/article/59/6/496/1660803">Window tinting</a> blocks around 95% of UVA radiation.</p> <p>In a separate study from Saudi Arabia, researchers fitted drivers with a <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC9797294/">wearable radiation monitor</a>. They found drivers were exposed to UV index ratings up to 3.5. (In Australia, sun protection <a href="https://www.cancer.org.au/cancer-information/causes-and-prevention/sun-safety/about-sunscreen/spf50-sunscreen">is generally recommended</a> when the UV index is 3 or above – at this level it takes pale skin about 20 minutes to burn.)</p> <p>So if you have your windows tinted, you should not have to wear sunscreen in the car.

Vitamin B6 is essential – but too much can be toxic. Here’s what to know to stay safe

<p><em><a href="https://theconversation.com/profiles/vasso-apostolopoulos-105605">Vasso Apostolopoulos</a>, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a> and <a href="https://theconversation.com/profiles/jack-feehan-1239419">Jack Feehan</a>, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a></em></p> <p>In recent weeks, <a href="https://www.abc.net.au/news/2025-01-08/vitamin-b6-toxicity-peripheral-neuropathy-health-supplements/104793006">reports have been circulating</a> about severe reactions in people who’ve taken over-the-counter vitamin B6 supplements.</p> <p>Vitamin B6 poisoning can injure nerves and lead to symptoms including numbness, tingling and even trouble walking and moving.</p> <p>In some cases, those affected <a href="https://www.abc.net.au/news/2025-01-28/vitamin-b6-toxicity-cases-rise-vitamins-supplements-tga-review/104863232">didn’t know the product contained</a> any vitamin B6.</p> <p>So what is vitamin B6, where is it found and how much is too much? Here’s what you need to know about this essential nutrient.</p> <h2>What is vitamin B6?</h2> <p>Vitamin B6 (also known as pyridoxine) is a group of six compounds that share a similar chemical structure.</p> <p>It is an essential nutrient, meaning we need it for normal body functions, but we can’t produce it ourselves.</p> <p><a href="https://www.eatforhealth.gov.au/nutrient-reference-values/nutrients/vitamin-b6">Adults aged 19–50</a> need 1.3mg of vitamin B6 per day. The recommended dose is lower for teens and children, and higher for those aged 51 and over (1.7mg for men and 1.5mg for women) and people who are breastfeeding or pregnant (1.9mg).</p> <p>Most of us get <a href="https://www.nhs.uk/conditions/vitamins-and-minerals/vitamin-b/">this in our diet</a> – largely from animal products, including meat, dairy and eggs.</p> <p>The vitamin is also available in a range of different plant foods, including spinach, kale, bananas and potatoes, so deficiency is <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC8150266/">rare</a>, even for vegetarians and vegans.</p> <p>The vitamin B6 we consume in the diet is inactive, meaning the body can’t use it. To activate B6, the liver transforms it into a compound called pyridoxal-5’-phosphate (PLP).</p> <p>In this form, vitamin B6 helps the body with more than 140 cellular functions, including building and breaking down proteins, producing red blood cells, regulating blood sugar and supporting brain function.</p> <p>Vitamin B6 is important for <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC6071262/">overall health</a> and has also been associated with reduced <a href="https://pubmed.ncbi.nlm.nih.gov/28376200/">cancer</a> risk and <a href="https://www.sciencedirect.com/science/article/abs/pii/S0098299716300395">inflammation</a>.</p> <p>Despite being readily available in the diet, vitamin B6 is also widely included in various supplements, multivitamins and other products, such as Berocca and energy drinks.</p> <h2>Should we be worried about toxicity?</h2> <p>Vitamin B6 toxicity is extremely rare. It <a href="https://europepmc.org/article/nbk/nbk470579?crsi=6624972170&amp;cicada_org_src=healthwebmagazine.com&amp;cicada_org_mdm=direct&amp;client=bot">almost never occurs from dietary intake alone</a>, unless there is a genetic disorders or disease that stops nutrient absorption (such as coeliac disease).</p> <p>This is because all eight vitamins in the B group are water-soluble. If you consume more of the vitamin than your body needs, it can be excreted readily and harmlessly in your urine.</p> <p>However, in some rare cases, <a href="https://pubmed.ncbi.nlm.nih.gov/37447150/">excessive vitamin B6</a> accumulates in the blood, resulting in a condition called peripheral neuropathy. We’re still not sure why this occurs in some people but not others.</p> <p>Peripheral neuropathy <a href="https://my.clevelandclinic.org/health/diseases/14737-peripheral-neuropathy">occurs when the sensory nerves</a> – those outside our brain and spinal cord that send information to the central nervous system – are damaged and unable to function. This can be caused by a wide range of diseases (and is most well known in type 2 diabetes).</p> <p>The most common symptoms are numbness and tingling, though in some cases patients may experience difficulty with balance or walking.</p> <p>We don’t know exactly how excess vitamin B6 causes peripheral neuropathy, but it is thought to <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC8483950/">interfere with how the neurotransmitter GABA</a> sends signals to the sensory nerves.</p> <p>Vitamin B6 can cause permanent damage to nerves. <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC10343656/">Studies have shown</a> symptoms improved when the person stopped taking the supplement, although they didn’t completely resolve.</p> <h2>What is considered excessive? And has this changed?</h2> <p><a href="https://www.cureus.com/articles/199499-vitamin-b6-toxicity-secondary-to-daily-multivitamin-use-a-case-report#!/">Toxicity usually occurs</a> only when people take supplements with high doses of B6.</p> <p>Until 2022, only products with more than 50mg of vitamin B6 were required to display a warning about peripheral neuropathy. But the <a href="https://www.tga.gov.au/news/safety-updates/peripheral-neuropathy-supplementary-vitamin-b6-pyridoxine">Therapeutic Goods Administration lowered this</a> and now requires any product containing more than 10mg of vitamin B6 to carry a warning.</p> <p>The Therapeutic Goods Administration has also halved the daily upper limit of vitamin B6 a product can provide – from 200mg to 100mg.</p> <p>These changes followed a review by the administration, after receiving 32 reports of peripheral neuropathy in people taking supplements. Two thirds of these people were taking less than 50mg of vitamin B6.</p> <p>The <a href="https://www.tga.gov.au/news/safety-updates/peripheral-neuropathy-supplementary-vitamin-b6-pyridoxine#what-should-health-professionals-do">Therapeutic Goods Administration acknowledges</a> the risk varies between individuals and a lot is unknown. Its review could not identify a minimum dose, duration of use or patient risk factors.</p> <h2>But I thought B vitamins were good for me?</h2> <p>Too much of anything can cause problems.</p> <p>The updated guidelines are likely to significantly lower the risk of toxicity. They also make consumers more aware of which products contain B6, and the risks.</p> <p>The Therapeutic Goods Administration will continue to monitor evidence and revise guidelines if necessary.</p> <p>While vitamin B6 toxicity remains very rare, there are still many questions about why some people get peripheral neuropathy with lower dose supplements.</p> <p>It could be that some specific vitamin B compounds have a stronger effect, or some people may have genetic vulnerabilities or diseases which put them <a href="https://www.sciencedirect.com/science/article/pii/S2161831322004781">at higher risk</a>.</p> <h2>So what should I do?</h2> <p>Most people don’t need to actively seek vitamin B6 in supplements.</p> <p>However, many reports to the Therapeutic Goods Administration were of vitamin B6 being added to supplements labelled as magnesium or zinc – and some weren’t aware they were consuming it.</p> <p>It is important to always check the label if you are taking a new medicine or supplement, especially if it hasn’t been explicitly prescribed by a health-care professional.</p> <p>Be particularly cautious if you are taking multiple supplements. While one multivitamin is unlikely to cause an issue, adding a magnesium supplement for cramping, or a zinc supplement for cold and flu symptoms, may cause an excessive vitamin B6 dose over time, and increase your risk.</p> <p>Importantly, pay attention to symptoms that may indicate peripheral neuropathy, such as pins and needles, numbness, or pain in the feet or hands, if you do change or add a supplement.</p> <p>Most importantly, if you need advice, you should talk to your doctor, dietitian or pharmacist.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/248443/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/vasso-apostolopoulos-105605">Vasso Apostolopoulos</a>, Distinguished Professor, Professor of Immunology, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a> and <a href="https://theconversation.com/profiles/jack-feehan-1239419">Jack Feehan</a>, Vice Chancellors Senior Research Fellow in Immunology, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Tonsils can grow back after they’ve been removed – here’s which other body parts can regenerate

<p><em><a href="https://theconversation.com/profiles/adam-taylor-283950">Adam Taylor</a>, <a href="https://theconversation.com/institutions/lancaster-university-1176">Lancaster University</a></em></p> <p>The human body is composed of over <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC6085824/">37 trillion cells</a>, each with a limited lifespan. These cells are continuously replaced to maintain organ and system function. Yet over time, or as a result of damage, the number of functioning cells can decrease to a level that causes symptoms or even organ failure.</p> <p>Regeneration of organs and systems is a scientific holy grail that relies on <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC9973391/">stem cells</a>, but due to their limited number and slow division rate, this isn’t a practical route to organ regeneration. It would take many years to repopulate all the cell types needed.</p> <p>However, some people see organs “reappear”, like <a href="https://edition.cnn.com/2025/01/02/health/tonsils-regrow-sore-throat/index.html">Katy Golden</a> who had her tonsils removed for a second time as an adult after they grew back over 40 years.</p> <p>One reason that tonsils may grow back is that one of the operations to remove them is a <a href="https://pubmed.ncbi.nlm.nih.gov/22431869/">partial tonsillectomy</a>. Only removing part of the tonsils leads to a quicker recovery and fewer complications, but around <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC5639321/">6% of children may see regrowth</a>, which may require further surgery in later life.</p> <p>Most people associate organ regrowth and regeneration with the liver. As little as <a href="https://www.nih.gov/news-events/nih-research-matters/cells-maintain-repair-liver-identified">10% of the liver</a> can regrow into a fully functioning liver. This is also how partial liver transplants allow the <a href="https://bmcsurg.biomedcentral.com/articles/10.1186/s12893-019-0606-5">donor to “regrow”</a> a normal sized and fully functioning liver.</p> <p>One organ that has a surprising capacity to regenerate is the spleen and sometimes it can regenerate without people realising.</p> <p>The spleen is a high-risk organ for injury and is the <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC4056798/">most commonly injured organ</a> in blunt abdominal trauma during traffic collisions, sporting injuries or trivial activities such as <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC8551460/">bumping into furniture</a>.</p> <p>The spleen is at high risk because it has lots of blood vessels and hence lots of blood, but is only surrounded by a <a href="https://pubmed.ncbi.nlm.nih.gov/31623879/">thin capsule</a> that can tear in trauma, allowing blood to leak out. This can <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC6783166/">result in death</a> if not treated promptly.</p> <p>What may also happen is small pieces of the spleen – sometimes just a few cells – can become free in the abdomen and go on to “grow” where they settle – termed <a href="https://ajronline.org/doi/10.2214/AJR.11.7896">splenosis</a>, going on to have <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC4762861/">similar functional activity</a> to a mature, normally located spleen. This can be beneficial for those who have to have their spleen removed due to traumatic injury, with some reports suggesting regeneration in up to <a href="https://pubmed.ncbi.nlm.nih.gov/2603609/">66% of patients</a>.</p> <p>In the last few years, our lungs have also been shown to have regenerative capacity. It is well known that smoking and other pollutants <a href="https://www.ncbi.nlm.nih.gov/books/NBK53021/">destroy the alveoli</a> (tiny air sacs) where oxygen is passed to the blood. Stopping smoking has been shown to allow cells that have avoided damage from the cancer-causing chemicals in tobacco smoke to help <a href="https://www.nature.com/articles/s41586-020-1961-1">regenerate and repopulate</a> the lining of parts of the airways with healthy cells.</p> <p>Where a lung has been removed, the remaining lung has to adapt to support the tissues of the body and ensure enough oxygen gets to them. Studies have shown that the remaining lung <a href="https://pubmed.ncbi.nlm.nih.gov/22808959/">increases the number of alveoli</a> it has, rather than the remaining alveoli compensating by getting bigger to take up more oxygen.</p> <p>It isn’t just organs inside that regenerate. One organ that constantly does so on a humongous scale is the skin.</p> <p>As the largest organ, it has multiple barrier functions to keep things such as <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC4529263/">water in</a> and <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC6283644/">germs out</a>. With a <a href="https://www.sciencedirect.com/science/article/abs/pii/S0378517322004057">surface area of almost 2m²</a>, the skin requires a significant amount of regeneration to replenish the 500,000,000 cells that are lost each day – that’s over <a href="https://pubmed.ncbi.nlm.nih.gov/15541634/">2g of skin cells per day</a>.</p> <h2>Tissue regeneration is much more common</h2> <p>One of the most active regenerative tissues is the endometrial lining of the uterus which is shed every 28 days as part of the menstrual cycle and goes through about <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC10308170/">450 cycles</a> of this during a woman’s life.</p> <p>This layer varies between <a href="https://pubs.rsna.org/doi/10.1148/rg.2017170008">0.5 and 18mm in thickness</a> depending on the stage of the menstrual cycle, the <a href="https://journals.physiology.org/doi/full/10.1152/physrev.00031.2019">functional cells</a> that are lost along with the blood from vessels that support a fertilised egg if it implants.</p> <p>Men’s genitalia can also show regeneration. <a href="https://www.nhs.uk/contraception/methods-of-contraception/vasectomy-male-sterilisation/what-is-it/">Vasectomy</a>, which removes a piece of the tube (<a href="https://www.cancer.gov/publications/dictionaries/cancer-terms/def/vas-deferens">vas deferens</a>) connecting the testes to the openings in the urethra, is used to reduce the chance of pregnancy by preventing sperm moving from the testes out of the penis.</p> <p>However, the cut ends of the ducts have shown regenerative capacity and reconnected. Some sections, where <a href="https://jamanetwork.com/journals/jamasurgery/article-abstract/536907">up to 5cm</a> has been restricted or removed, have shown regeneration, even through <a href="https://bmcurol.biomedcentral.com/articles/10.1186/1471-2490-6-25">scar tissue</a>. This “recanalisation” can result in unexpected pregnancies.</p> <p>Bone is another tissue that can regenerate. If you’ve ever broken a bone, you’ll know that it repairs so that (eventually) you will regain function.</p> <p>This process of repairing the break takes six to eight weeks. But the process of regenerating the bone architecture and strength <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC5365304/">continues for months and years</a> beyond this date.</p> <p>However, with <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC6667184/">increasing age</a> and in <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC5643776/">post-menopausal woman</a>, this process slows and the bone may not regenerate to its <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC6667184/">previous strength</a> or <a href="https://pubmed.ncbi.nlm.nih.gov/15763602/">structure</a>.</p> <p>Where paired organs exist and one is lost, there is good evidence that the remaining organ can increase its functional ability to help the body cope with maintaining function. For example, when one kidney is removed, the remaining kidney <a href="https://www.kidneyregistry.com/for-donors/kidney-donation-blog/what-changes-after-kidney-donation/">enlarges</a> to handle the extra workload, filtering blood and eliminating waste efficiently.</p> <p>Although organ regeneration is rare, it does happen and typically takes years to manifest because organs are complex structures. Work continues to try to understand how scientists can develop this knowledge to help with the shortage of donor organs. Thankfully, tissue regeneration happens much more often than many people might suppose, and it is a much-needed part of staying alive.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/246653/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/adam-taylor-283950"><em>Adam Taylor</em></a><em>, Professor and Director of the Clinical Anatomy Learning Centre, <a href="https://theconversation.com/institutions/lancaster-university-1176">Lancaster University</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Electrolyte beverages can help your body stay balanced − but may worsen symptoms if you’re sick

<p><em><a href="https://theconversation.com/profiles/bryn-beeder-2260643">Bryn Beeder</a>, <a href="https://theconversation.com/institutions/miami-university-1934">Miami University</a></em></p> <p>For generations, <a href="https://performancepartner.gatorade.com/products">Gatorade</a> and similar electrolyte beverages have been helpful tools for athletes seeking a competitive edge.</p> <p>In 1965, <a href="https://explore.research.ufl.edu/historical-markers/gatorades-birthplace/">Dr. Robert Cade and a team of scientists</a> at the University of Florida College of Medicine created Gatorade to help their football players combat heat exhaustion and muscle cramps during long practices in extreme temperatures.</p> <p>The drink’s winning formula of water, sodium, potassium and sugar works effectively with the human body to keep users hydrated, refueling them with energy and optimizing muscle function.</p> <p>While I don’t work for or receive funding from Gatorade, <a href="https://miamioh.edu/profiles/ehs/bryn-beeder.html">as a registered dietitian and nutrition instructor</a>, I’ve watched how specific electrolyte beverages can be handpicked to boost hydration in hospitalized patients, student athletes and even myself.</p> <p>And while Gatorade was one of the first electrolyte beverages heavily marketed to consumers, its ingredient combination has paved the way for the creation of even more sport and electrolyte beverages on the grocery store shelves today. If you’re looking to gain a specific nutritional edge from a sports drink, you can seek out a registered dietitian for an individualized plan. Otherwise, if you’ve ever wondered what makes these colorful beverages a nutrition attraction, here’s a closer look at some key ingredients.</p> <h2>The importance of hydration</h2> <p>Whether people are athletes or not, the human body is constantly losing water through normal human functions such as sweating, urinating and even breathing. When water is lost, the body also excretes key electrolytes such as <a href="https://www.cdc.gov/salt/sodium-potassium-health/index.html">potassium and sodium</a>. These electrolytes are crucial for everything from heart function to muscle contractions.</p> <p><a href="https://my.clevelandclinic.org/health/diagnostics/21790-electrolytes">Electrolytes</a> get their “electro” name from having an electrical charge when dissolved in water. This charge allows them to work throughout the body in chemical reactions that maintain normal brain functioning, balance fluids inside and outside of body cells and even balance how acidic or alkaline your blood is.</p> <figure><iframe src="https://www.youtube.com/embed/l3VWb0mUS7Y?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">Electrolytes can help you rehydrate after a workout by balancing fluids in our cells.</span></figcaption></figure> <p>Major stress on the body can accelerate the <a href="https://my.clevelandclinic.org/health/diseases/9013-dehydration">dehydration process</a> – whether it’s intentional, like running a 5K, or unintentional, like getting a nasty stomach bug. If left unchecked, dehydration can cause more serious complications, such as fainting and irregular heartbeats.</p> <p>To prevent these complications, you need to replenish the fluids and electrolytes you’re losing. Stressful scenarios such as exercise and sickness are a perfect time to consider an electrolyte replacement drink.</p> <h2>A closer look at Gatorade’s ingredients</h2> <p>Water, the main ingredient in most sports drinks, <a href="https://www.eatright.org/health/essential-nutrients/water/how-much-water-do-you-need">hydrates you</a>. The human body is made up of <a href="https://www.usgs.gov/special-topics/water-science-school/science/water-you-water-and-human-body">approximately 60% water</a>, so to stay hydrated, it is important to listen to your body and drink water regularly. When the body’s water volume is decreased, it sends thirst signals to the brain.</p> <p>However, these signals often lag behind your hydration status. So, once you feel thirsty, your body is likely already slightly dehydrated. For a more accurate hydration assessment, check the <a href="https://health.clevelandclinic.org/what-urine-color-means">color of your urine</a>. Darker yellow or golden urine? Grab some water. Pale yellow or clear urine? Keep up the good hydration.</p> <p><a href="https://my.clevelandclinic.org/health/diagnostics/21790-electrolytes">Sodium, another ingredient in Gatorade, attracts water</a>. When you are dehydrated, the body’s blood is more concentrated because less water is circulating overall.</p> <p>When you have a lower blood volume, your blood vessels don’t expand as much as they normally would – ultimately lowering blood pressure. If blood pressure drops too quickly due to dehydration, you might feel dizziness, lightheadedness, nausea or weakness.</p> <p>The good news is that sodium actively pulls water into the bloodstream. So during an intense workout or while dealing with a dehydrating illness, consuming a salty snack or sports beverage can help.</p> <p><a href="https://health.clevelandclinic.org/potassium">The potassium in Gatorade regulates muscle contractions</a>. This electrolyte is especially critical for regulating your heartbeat, and it also aids in normal skeletal muscle contractions. If the body lacks enough potassium, painful muscle cramps or dizziness can disrupt your workout or day.</p> <p><a href="https://my.clevelandclinic.org/health/articles/15416-carbohydrates">Sugar provides quick energy</a> and nutrient absorption power. A traditional Gatorade beverage contains glucose and dextrose, which are both known as simple sugars. A simple sugar is one that the body can quickly digest and absorb, with the goal of quickly increasing blood sugar.</p> <p>Strenuous aerobic exercise or strength training for longer than 60 minutes, performing activities in very hot or humid climates, or the physical strain of an unwelcome illness can all rev the body’s metabolism and quickly deplete <a href="https://medlineplus.gov/bloodglucose.html">blood glucose</a>. When glucose levels drop, you may experience fatigue, weakness, lightheadedness, nausea or difficulty concentrating.</p> <p>The nutrient combination found in Gatorade was designed with athletes in mind, but it is also sometimes discussed as a remedy to consider during an unpleasant bout of gastrointestinal illness. <a href="https://my.clevelandclinic.org/health/diseases/4108-diarrhea">Diarrhea</a> and <a href="https://my.clevelandclinic.org/health/symptoms/8106-nausea--vomiting">vomiting</a> are easy routes for electrolytes such as sodium and potassium to escape.</p> <p>Energy drinks’ combination of simple sugars, water and electrolytes may be one strategy to maintain hydration during a time when food and fluids are difficult to stomach.</p> <p>However, be cautious – many traditional sports drinks have a high sugar content aimed at refueling lost energy during a workout. When that same sugar content is introduced to an upset gastrointestinal tract, it can pull in extra water, leading to more diarrhea. If you find yourself in this situation, here are some other options to consider.</p> <p>Opt for a lower-sugar electrolyte beverage. Beverages to consider include Pedialyte or even a broth-based soup. Both will hydrate with minimal added sugar content.</p> <p>The human body is incredibly efficient at managing nutrients in the blood. In most cases, balanced meals and water consumption are enough to meet your daily nutrient needs. During intense physical exercise or an unexpected illness, however, the body may struggle to maintain its usual balance.</p> <p>If you notice unusual symptoms such as dizziness, fatigue or persistent thirst, your body will need attention. In specific cases of dehydration from exercise or illness, a sports drink like Gatorade can be a simple tool to help you bounce back to your best self.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/243763/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/bryn-beeder-2260643">Bryn Beeder</a>, Visiting Instructor in Kinesiology, Nutrition, and Health, <a href="https://theconversation.com/institutions/miami-university-1934">Miami University</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

You can train your nose – and 4 other surprising facts about your sense of smell

<p><em><a href="https://theconversation.com/profiles/lynn-nazareth-1650578">Lynn Nazareth</a>, <a href="https://theconversation.com/institutions/csiro-1035">CSIRO</a></em></p> <p>Would you give up your sense of smell to keep your hair? What about your phone?</p> <p>A <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC8946147/">2022 US study</a> compared smell to other senses (sight and hearing) and personally prized commodities (including money, a pet or hair) to see what people valued more.</p> <p>The researchers found smell was viewed as much less important than sight and hearing, and valued less than many commodities. For example, half the women surveyed said they’d choose to keep their hair over sense of smell.</p> <p>Smell often goes under the radar as one of the least valued senses. But it is one of the <a href="https://royalsocietypublishing.org/doi/10.1098/rsob.200330">first sensory systems vertebrates developed</a> and is linked to your mental health, memory and more.</p> <p>Here are five fascinating facts about your olfactory system.</p> <h2>1. Smell is linked to memory and emotion</h2> <p>Why can the waft of fresh baking trigger joyful childhood memories? And why might a certain perfume jolt you back to a painful breakup?</p> <p>Smell is directly linked to both your memory and emotions. This connection was first established by American psychologist <a href="https://www.jstor.org/stable/16002">Donald Laird in 1935</a> (although French novelist <a href="https://www.penguin.co.uk/articles/2020/07/more-than-cake-unravelling-the-mysteries-of-proust-s-madeleine">Marcel Proust had already made it famous</a> in his reverie about the scent of madeleines baking.)</p> <p>Odours are first captured by special olfactory nerve cells inside your nose. These cells extend upwards from the roof of your nose towards the smell-processing centre of your brain, called the <a href="https://www.ncbi.nlm.nih.gov/books/NBK55972/">olfactory bulb</a>.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/640871/original/file-20250107-15-vili6v.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/640871/original/file-20250107-15-vili6v.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/640871/original/file-20250107-15-vili6v.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=592&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/640871/original/file-20250107-15-vili6v.jpg?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=592&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/640871/original/file-20250107-15-vili6v.jpg?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=592&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/640871/original/file-20250107-15-vili6v.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=744&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/640871/original/file-20250107-15-vili6v.jpg?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=744&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/640871/original/file-20250107-15-vili6v.jpg?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=744&amp;fit=crop&amp;dpr=3 2262w" alt="Diagram showing odour particles travelling through the nose into the brain." /></a><figcaption><span class="caption">Smells are first detected by nerve cells in the nose.</span> <span class="attribution"><a class="source" href="https://www.shutterstock.com/image-illustration/sense-smell-detailed-illustration-olactory-region-1832630776">Axel_Kock/Shutterstock</a></span></figcaption></figure> <p>From the olfactory bulb they form direct connection with the brain’s <a href="https://my.clevelandclinic.org/health/body/limbic-system">limbic system</a>.

In most cases it’s temporary, returning to normal within a few weeks.</p> <p>This is because every few months <a href="https://www.nature.com/articles/s41593-020-0587-9">your olfactory nerve cells die and are replaced</a> by new cells.</p> <p>We’re not entirely sure how this occurs, but it likely involves your nose’s <a href="https://www.cell.com/heliyon/fulltext/S2405-8440(24)05979-6">stem cells</a>, <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC2387238/#:%7E:text=When%20the%20olfactory%20nerves%20and,reestablish%20connections%20with%20the%20bulb">the olfactory bulb</a> and <a href="https://onlinelibrary.wiley.com/doi/10.1002/cne.23694">other cells</a> in the olfactory nerves.</p> <p>Other areas of your nervous system – including your brain and spinal cord – cannot regenerate and repair after an injury.</p> <p>Constant regeneration may be a protective mechanism, as the olfactory nerves are vulnerable to damage caused by the external environment, including toxins (such as cigarette smoke), chemicals and pathogens (<a href="https://academic.oup.com/jid/article/210/3/419/2908527">such as the flu virus</a>).</p> <p>But following a COVID infection some people might continue to experience a loss of smell. Studies suggest <a href="https://www.sciencedirect.com/science/article/pii/S0092867421012824?via%3Dihub">the virus</a> and a <a href="https://www.science.org/doi/10.1126/scitranslmed.add0484">long-term immune response</a> damages the cells that allow the olfactory system to regenerate.</p> <h2>3. Smell is linked to mental health</h2> <p>Around <a href="https://journals.sagepub.com/doi/full/10.1177/1945892420946254">5% of the global population</a> suffer from anosmia – total loss of smell. An estimated 15-20% suffer partial loss, known as hyposmia.</p> <p>Given smell loss is often a primary and long-term symptom of COVID, these <a href="https://www.nature.com/articles/s41598-024-53919-y">numbers are likely to be higher</a> since the pandemic.</p> <p>Yet in Australia, the prevalence of olfactory dysfunction <a href="https://www1.racgp.org.au/ajgp/2021/september/an-approach-to-olfactory-impairments">remains surprisingly understudied</a>.</p> <p>Losing your sense of smell <a href="https://academic.oup.com/chemse/article/doi/10.1093/chemse/bjab037/6342176">is shown to impact your personal and social relationships</a>. For example, it can mean you miss out on shared eating experiences, or cause changes in sexual desire and behaviour.</p> <p>In older people, declining ability to smell is associated with a <a href="https://academic.oup.com/biomedgerontology/article/79/1/glad139/7207364?login=true">higher risk of depression</a> and <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0107541">even death</a>, although we still don’t know why.</p> <h2>4. Loss of smell can help identify neurodegenerative diseases</h2> <p>Partial or full loss of smell is <a href="https://www.sciencedirect.com/science/article/pii/S1474442217301230?via%3Dihub">often an early indicator for a range of neurodegenerative diseases</a>, including Alzheimer’s and Parkinson’s diseases.</p> <p>Patients <a href="https://www.neurology.org/doi/abs/10.1212/wnl.0000000000001265">frequently report losing their sense of smell</a> years before any symptoms show in body or brain function. However many people are not <a href="https://onlinelibrary.wiley.com/doi/10.1002/9781118971758.ch18">aware they are losing their sense of smell</a>.</p> <p>There are ways you can determine if you have smell loss and to what extent. You may be able to visit a formal <a href="https://www.epworth.org.au/our-services/rehabilitation/brain-injury-and-neurological-disorders/olfactory-impairment-clinic#:%7E:text=Epworth%20is%20the%20first%20rehabilitation,and%20associated%20changes%20in%20taste.">smell testing centre</a> or do a <a href="https://esurvey.uniklinikum-dresden.de/pub/index.php/678693">self-test</a> at home, which assesses your ability to identify household items like coffee, wine or soap.</p> <h2>5. You can train your nose back into smelling</h2> <p>“Smell training” is emerging as a <a href="https://link.springer.com/article/10.1007/s00405-024-08733-7">promising experimental treatment option</a> for olfactory dysfunction. For people experiencing smell loss after COVID, it’s been show to <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC9309586/">improve the ability to detect and differentiate odours</a>.</p> <p>Smell training (or “olfactory training”) was first tested in 2009 in a <a href="https://onlinelibrary.wiley.com/doi/10.1002/lary.20101">German psychology study</a>. It involves sniffing robust odours — such as floral, citrus, aromatic or fruity scents — at least twice a day for 10—20 seconds at a time, usually over a 3—6 month period.</p> <p>Participants are asked to focus on the memory of the smell while sniffing and recall information about the odour and its intensity. This is <a href="https://jamanetwork.com/journals/jamaotolaryngology/fullarticle/2782042">believed to help reorganise the nerve connections</a> in the brain, although the exact mechanism behind it is unclear.</p> <p>Some studies recommend using a <a href="https://onlinelibrary.wiley.com/doi/10.1002/lary.20101">single set of scents</a>, while others recommend <a href="https://onlinelibrary.wiley.com/doi/full/10.1002/lary.25245">switching to a new set of odours</a> after a certain amount of time. However <a href="https://onlinelibrary.wiley.com/doi/full/10.1002/lary.26985">both methods show significant improvement</a> in smelling.</p> <p>This training has also been shown to alleviate depressive symptoms and improve cognitive decline both in <a href="https://onlinelibrary.wiley.com/doi/full/10.1002/gps.4725">older adults</a> and those suffering from <a href="https://pubmed.ncbi.nlm.nih.gov/34749425/">dementia</a>.</p> <p>Just like physiotherapy after a physical injury, olfactory training is thought to act like <a href="https://www.sciencedirect.com/science/article/pii/S0149763422003426#sec0005">rehabilitation for your sense of smell</a>. It retrains the nerves in your nose and the connections it forms within the brain, allowing you to correctly detect, process and interpret odours.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/245366/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/lynn-nazareth-1650578">Lynn Nazareth</a>, Research Scientist in Olfactory Biology, <a href="https://theconversation.com/institutions/csiro-1035">CSIRO</a></em></p> <p><em>Image credits: Shutterstock</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

How can I keep my cat happy? 5 tips from a vet to help your feline friend live their best life

<p><em><a href="https://theconversation.com/profiles/anne-quain-12802">Anne Quain</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>Around <a href="https://animalmedicinesaustralia.org.au/report/pets-in-australia-a-national-survey-of-pets-and-people-2/">one third of Australian households live with at least one cat</a>, yet surveys tell us the cats’ <a href="https://journals.sagepub.com/doi/10.1177/1098612X19890189">needs are not being met</a>.</p> <p>Cats may <a href="https://www.sup.org/books/media-studies/unified-theory-cats-internet">rule the internet</a>, but humans often misconstrue feline behaviour. Earlier this year, the Washington Post boldly declared <a href="https://www.washingtonpost.com/home/2024/03/12/cats-behavior-misunderstood/">cat’s arent jerks – they’re just misunderstood</a>. This was prompted by research showing that, contrary to unhelpful stereotypes, <a href="https://www.sciencedirect.com/science/article/pii/S1090023323000795">cats are not antisocial</a>. They can and do bond closely with humans.</p> <p>The more we learn about cats, the more we realise they are complex individuals with unique <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC8300181/">personalities</a> and preferences, capable of <a href="https://www.nature.com/articles/s41598-024-74006-2">learning</a>.</p> <p>From understanding your cat’s language to keeping them safe and healthy – here are science-backed tips to improve the lives of your feline flatmates.</p> <h2>1. Pay attention to body language</h2> <p>Cats communicate with humans using body language and vocalisation. However, while cats direct meows at humans, and the meows vary depending on the context, humans <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC7765146/">are not great at decoding them</a>. But we can read cat body language.</p> <p>For example, slow blinking is likely to indicate a <a href="https://www.nature.com/articles/s41598-020-73426-0">positive emotional state</a>. Cats who are not happy (for example, don’t want to be touched) will freeze, move away, flatten their ears, hiss, or – if they feel they have no other option – scratch or bite.</p> <p>It is better to allow cats to approach you on their terms, rather than pushing for social interaction. A cat approaching you with their tail up is giving a <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC8469685/">friendly signal</a>, while a tail swishing from side to side signals annoyance.</p> <p>Cats should always have the option to opt out of any interaction, like being touched. If you aren’t sure, just “<a href="https://www.companionanimalpsychology.com/p/purr-science-of-making-your-cat-happy.html">ask</a>”: stop patting them. If they walk away, they’re not keen. If they rub their head against you, they want to continue the interaction.</p> <h2>2. Provide a healthy environment</h2> <p>The American Association of Feline Practitioners and the International Society of Feline Medicine have agreed upon <a href="https://journals.sagepub.com/doi/full/10.1177/1098612X13477537">five pillars of a healthy feline environment</a>:</p> <ol> <li> <p>A safe space so that cats can retreat if frightened.</p> </li> <li> <p>Multiple, separated key resources (food, water, toileting areas, scratching areas, play areas and resting or sleeping areas) so that cats can comfortably conduct their daily activities.</p> </li> <li> <p>Opportunity for play and predatory behaviour, such as games with wand toys that simulate hunting.</p> </li> <li> <p>Positive, consistent and predictable human-cat interactions, respecting a cat’s choice about whether and how they interact.</p> </li> <li> <p>Respecting the importance of a cat’s senses by avoiding undesirable stimuli (strong smells and loud noises), and providing desirable sensory stimulation (for example, use of <a href="https://theconversation.com/are-catnip-and-treats-like-it-safe-for-cats-heres-how-they-affect-their-minds-and-moods-214947">catnip or silver vine</a>).</p> </li> </ol> <p>These pillars provide a useful checklist. If you read this and realise your cat’s food and water are right next to the litter tray, you can improve your cat’s environment (and their experiences of eating and toileting) by separating these resources right now.</p> <h2>3. Clean the litter tray!</h2> <p>A litter tray may represent an unpleasant chore to you, but the importance of a spacious litter tray to your cat cannot be overstated. Cats <a href="https://www.sciencedirect.com/science/article/pii/S0376635716302972">prefer using a clean litter tray</a>, even if they are the only cat in the household.</p> <p>Cats like to <a href="https://www.sciencedirect.com/science/article/pii/S016815911730151X">spend time in the tray</a> before, during and after toileting, and they generally <a href="https://www.sciencedirect.com/science/article/pii/S1558787814000033">prefer a large tray</a>.</p> <p>Poor litter hygiene is associated with a risk of urinary problems, which can be <a href="https://onlinelibrary.wiley.com/doi/10.1111/jvim.16389">life-threatening</a>. A <a href="https://doi.org/10.1177/1098612X19890189">survey of over 12,000 Australian cat owners</a> found that urinary problems were more common in households with a low number of litter trays per cat, less frequent removal of faeces from the trays, and the use of crystal-type cat litter.</p> <p>If you switch the type of litter you provide, a <a href="https://www.mdpi.com/2076-2615/12/8/946">slow transition</a> is recommended to allow cats to get used to the change.</p> <h2>4. Read the room</h2> <p>Do you have more than one cat? Tension between household cats is common but often overlooked, as it’s not always physical fighting. Signs of inter-cat tension can include prolonged staring, or even blocking the use of resources such as the litter tray or cat door, to prevent other cats from using them.</p> <p>In their <a href="https://journals.sagepub.com/doi/10.1177/1098612X241263465">2024 intercat-tension guidelines</a>, the American Association of Feline Practitioners note this can case chronic fear, anxiety and stress-related illnesses in cats.</p> <p>Learning to recognise and manage tension between household cats can improve the welfare of all parties.</p> <p>When you love your cat, it is tempting to seek to amplify the joy by adopting another. But many cats prefer to be the only cat in the household, and don’t cope well with a <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC10083434/">feline flatmate</a>. If they have positive interactions with familiar, trusted humans, they’re unlikely to be lonely.</p> <h2>5. Keep cats and other animals safe</h2> <p>Historically, domesticated cats earned their keep <a href="https://www.sciencedirect.com/science/article/pii/S0169534720300100">protecting grain stores</a> from rodents. But what constitutes responsible cat ownership has changed. Around 65% of Australia’s cat owners <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC10215893/">confine their cats</a> indoors always, while 24% keep their cats confined at night.</p> <p>A major driver for indoor-only housing of cats is their <a href="https://theconversation.com/one-cat-one-year-110-native-animals-lock-up-your-pet-its-a-killing-machine-138412">predation of wildlife</a>. Another is concerns about roaming-associated risks to cats, including cat fights, infectious diseases (such as <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC9546031/">feline immunodeficiency virus or FIV</a>), misadventure and motor vehicle trauma. But owners of cats kept entirely indoors were more likely to report <a href="https://www.sciencedirect.com/science/article/abs/pii/S0168159119301054?via%3Dihub">“problem” behaviours</a>.</p> <p>Ideally, cats shouldn’t be allowed to free-roam unsupervised where they can harm wildlife, even within the bounds of the property where you live. More than a third of local councils in Australia <a href="https://www.abc.net.au/news/2024-05-19/banning-pet-cats-roaming-native-animals-billions-dollars-council/103856000">now require</a> cats to be contained overnight or 24 hours a day.</p> <p>Outdoor access provides sensory stimulation, with different sights, sounds and smells. Alternatives to free roaming include providing access to a well-designed cat run, harness-training your cat, or supervising your cat.</p> <p>Cats who don’t leave home unless they’re moving house or being taken to the vet, quickly learn to associate the cat carrier with a trip to an unfamiliar environment. It doesn’t take a genius to work out that a vet visit is imminent when the carrier comes out.</p> <p>But that negative association can be changed. <a href="https://www.sciencedirect.com/science/article/pii/S0168159118302703">Cats who were rewarded with treats</a> when they approached, stepped inside or rested in the carrier for six weeks were much less stressed during veterinary visits.</p> <p>Cats are intelligent, and contrary to popular opinion, can be trained. The process can be enriching for cats and humans alike. With patience and commitment, <a href="http://www.smallanimaltalk.com/2017/04/book-review-trainable-cat-plus-that.html">you can train your cat</a> – from a simple “sit” to voluntarily stepping into the cat carrier.</p> <p>In short, give cats choice, respect their “cat-ness”, pay attention to their needs and try to see our world from their point of view. Your cat will be happier for it.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/242774/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/anne-quain-12802">Anne Quain</a>, Senior Lecturer, Sydney School of Veterinary Science, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p><em>Image credits: Shutterstock</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Even calm people can fly into a rage behind the wheel. Here’s how to curb your road rage – before it’s too late

<p><em><a href="https://theconversation.com/profiles/milad-haghani-1454675">Milad Haghani</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a></em></p> <p>If someone bumps into us on the footpath or in the mall, we’re generally quite forgiving. We instinctively apologise or step aside, and usually don’t scream at, stalk, or attack the other person.</p> <p>But put us in a car, and <a href="https://x.com/Boenau/status/1755234912540459059">something changes</a>. People who appear calm in everyday life suddenly tailgate, honk, or shout at strangers. <a href="https://www.sciencedirect.com/science/article/pii/S0925753524002467?casa_token=76NSmREtG8MAAAAA:yFEcndOLjARRfthZMFwOQ3UmPeqgJEwSuAvkaA51rH8fA7v8RzHDamohBhf8Ai7jb3Nrp98pz4I">Problems at work</a> or home can suddenly explode in the form of righteous anger toward other road users.</p> <p>Road rage <a href="https://www.sciencedirect.com/science/article/pii/S0001457523000192">increases crash risk</a>, and victims of road rage incidents often have <a href="https://www.mynrma.com.au/media/press-releases/2024/nrma-releases-worrying-road-rage-data">children in the car</a> with them.</p> <p>So, why does driving <a href="https://www.sciencedirect.com/science/article/pii/S0022437524000914?dgcid=raven_sd_recommender_email">bring out the worst in us</a>?

One way researchers <a href="https://www.sciencedirect.com/science/article/pii/S1369847815001722">measure</a> this is via a testing tool known as the <a href="https://www.yorku.ca/rokada/psyctest/driving.pdf">Driving Anger Scale</a>.</p> <p>Data from many studies using this test show drivers who are more prone to anger in general are <a href="https://research.monash.edu/en/publications/driving-anger-as-a-psychological-construct-twenty-years-of-resear">more likely to turn that anger into aggression</a>. They get annoyed by more things, are quicker to act on their feelings, take more risks, and as a result, are more likely to be involved in anger-related crashes.</p> <p>Research suggests that while female drivers experience anger just as much as male drivers, they are less likely to act on it in a <a href="https://www.turkpsikiyatri.com/PDF/C18S3/en/angerExpression.pdf">negative way</a>.</p> <p>Female drivers tend to feel more intense anger in certain situations, such as when <a href="https://www.sciencedirect.com/science/article/pii/S1369847815001722#f0010">faced with hostile gestures or traffic obstructions</a>, compared to their male counterparts.</p> <h2>What can I do to reduce my road rage?</h2> <p>In a car, we’re physically separated from others, which creates a sense of distance and anonymity – two factors that lower our usual social filters. Encounters feel fleeting.</p> <p>There’s a good chance you won’t be held accountable for what you or say or do, compared to if you were outside the car.

There’s a link between walking speed and ageing well. Here’s how you can improve your pace

<p><a href="https://theconversation.com/profiles/andres-rafales-perucha-1528635"><em>Andrés Ráfales Perucha</em></a><em>, <a href="https://theconversation.com/institutions/universidad-san-jorge-5704">Universidad San Jorge</a> and <a href="https://theconversation.com/profiles/pablo-gargallo-aguaron-1528652">Pablo Gargallo Aguarón</a>, <a href="https://theconversation.com/institutions/universidad-san-jorge-5704">Universidad San Jorge</a></em></p> <p>For decades, we have known that the way you walk, in particular your walking speed, is tied to your health. One study has even proposed that it be considered <a href="https://pubmed.ncbi.nlm.nih.gov/24812254/">a vital sign</a>, much like heart rate and blood pressure.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/26861693/">Various studies</a> have found a link between low walking speed in adults over 65 and a greater risk of cognitive impairment, cardiovascular disease, falls (which could lead to fractures), hospitalisation, and even an increased overall mortality rate.</p> <p>A higher walking speed, on the other hand, is associated with increased functional capacity, meaning a better ability to move around and do activities independently. It is also linked to <a href="https://www.thelancet.com/journals/lanhl/article/PIIS2666-7568(24)00092-8/fulltext">greater longevity</a>.</p> <p>But how fast should you walk? <a href="https://www.sciencedirect.com/science/article/abs/pii/S1568163714000646?dgcid=api_sd_search-api-endpoint">Studies</a> recommend a few simple tests, which principally consist of timing how long it takes a person to walk between two points at their usual pace.</p> <p>This <a href="https://www.physio-pedia.com/4_Metre_Walk_Test">test</a> is done over a distance of four metres. A speed of under 0.8 metres per second is associated with a greater risk of frailty.</p> <h2>How to improve walking speed</h2> <p>While there is slight disagreement as to the best exercise for increasing walking speed, the pattern that seems most effective is <a href="https://pubmed.ncbi.nlm.nih.gov/34409961/">multicomponent training</a>, which includes several different forms of exercise:</p> <ol> <li> <p><strong>Balance exercises</strong> can help improve stability and prevent falls. Examples include walking in a straight line putting one foot in front of the other, or standing on one leg, alternating every 10-15 seconds.</p> </li> <li> <p><strong>Flexibility exercises</strong> can improve mobility and reduce risk of injury. The benefits of movement in alleviating back pain are <a href="https://theconversation.com/back-pain-why-exercise-can-provide-relief-and-how-to-do-it-safely-162888">well documented</a>.</p> </li> <li> <p><strong>Muscular exercises</strong> help build strength in the legs, buttocks and other body areas. These can be as straightforward as standing up and sitting down in a chair.</p> </li> <li> <p><strong>Aerobic exercise</strong> improves stamina, and can include walking itself, or <a href="https://theconversation.com/seven-reasons-nordic-walking-is-better-for-you-than-the-normal-kind-187391">Nordic walking</a> (with hiking poles).</p> </li> </ol> <h2>How much aerobic exercise do we need?</h2> <p>The main <a href="https://www.who.int/publications/i/item/9789240014886">guides</a> on physical activity recommend that, provided they are physically and medically able, each adult should do at least 150 minutes of moderately intense aeoribic exercise per week.</p> <p>“Moderate” means you are not too out of breath to hold a conversation, but enough to notice an increased heart and breathing rate. There are few reasons not to do this kind of exercise, and it is beneficial for people with chronic illnesses, including cardiovascular issues, metabolic conditions, or even cancer.</p> <h2>Muscle strength: How, and how much?</h2> <p>Strengthening exercises have traditionally been recommended 2 to 3 times a week, with at least one set per exercise session of the main muscle groups: legs, buttocks, pectorals, back and arms.</p> <p>However, more recent studies suggest that doing less intense but more frequent strengthening exercises may be an effective way to <a href="https://pubmed.ncbi.nlm.nih.gov/34822137/">maintain muscle mass and strength</a>. This would mean doing them almost every day, including even small exercise “snacks” throughout the day.</p> <h2>Use it or lose it</h2> <p>If we don’t train them, muscle mass and strength decrease over time. This not only affects our mobility, but also increases the risk of health problems and even death. A little daily exercise can make a big difference. We therefore recommend that you try to maintain your physical condition as much as possible, both to improve your immediate health and prevent future problems.</p> <p>If you do not know where to start, the best option is always to consult a professional. If you have difficulties or limitations in exercising, a physiotherapist can help you to build a specialised exercise plan, or can adapt one to your needs.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/245880/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/andres-rafales-perucha-1528635">Andrés Ráfales Perucha</a>, Fisioterapeuta y Personal Docente e Investigador de la Universidad San Jorge.

Christmas can be challenging for people with hearing loss. Here are 7 ways you can help

<p><em><a href="https://theconversation.com/profiles/katie-ekberg-1534998">Katie Ekberg</a>, <a href="https://theconversation.com/institutions/flinders-university-972">Flinders University</a> and <a href="https://theconversation.com/profiles/louise-hickson-2280688">Louise Hickson</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a></em></p> <p>For many people, Christmas can be the most social time of the year. The holiday period is often filled with parties, lunches, dinners and celebrations of all kinds with family, friends and colleagues.</p> <p>For adults with hearing loss, however, these social gatherings can bring unique challenges. Communicating with others can be difficult, particularly in group conversations. And the more <a href="https://www.tandfonline.com/doi/full/10.1080/14992027.2019.1670363">background noise</a> there is (for example, Christmas music or children playing), the harder it is.</p> <p>For age-related or acquired hearing loss, hearing ability typically starts to decline from <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0107720">age 50 onwards</a>. <a href="https://www.health.gov.au/hearing-health/resources/publications/one-in-six-australians-experience-hearing-loss-poster-0?language=en">One in six Australians</a> experience some hearing loss, so it’s possible someone around your Christmas dinner table will be struggling to hear.</p> <p>Unfortunately, many adults with hearing loss suffer these challenges in silence. Our <a href="https://www.tandfonline.com/doi/full/10.1080/14992027.2023.2293651">research</a> shows adults with hearing loss often hide their hearing loss from others, even close family members and friends, because of feeling shame due to stigma.</p> <p>But there are some things you can do to ensure a loved one with hearing loss is included this Christmas.</p> <h2>Stigma and stereotypes</h2> <p>Stigma is when someone is treated differently by others due to a particular physical or social attribute.</p> <p>Across a <a href="https://www.tandfonline.com/doi/full/10.1080/14992027.2023.2293651">series of studies</a>, we conducted surveys and interviews with adults with hearing loss, their families and hearing care professionals to explore experiences of stigma for adults with hearing loss. Our research also included video recordings of real-life conversations between adults with hearing loss and their families and friends.</p> <p>The <a href="https://www.tandfonline.com/doi/full/10.1080/14992027.2024.2353862">results</a> suggested people often associate hearing loss with negative stereotypes of ageing, disability, reduced intelligence, having a problem or weakness, and difference. For example, one participant with hearing loss told us:</p> <blockquote> <p>Once they are aware that you can’t really comprehend or hear what they’re saying, they treat you different. And it’s not always positive, it’s quite often negative […] Even people who are familiar with you, my twin brother, he thinks that there’s something wrong with me because I can’t hear him properly.</p> </blockquote> <p>Old age was the most common stereotype associated with hearing loss. For example, one adult with hearing loss commented:</p> <blockquote> <p>I guess it’s just a sign of ageing. Like wearing glasses and grey hair.</p> </blockquote> <p>But as hearing can start declining from middle age, many adults experiencing hearing difficulties do not fit this stereotype.</p> <p>We see this stereotype appear in popular media as well. For example, in the TV show Bluey, the character Bingo dresses up as a “<a href="https://www.bluey.tv/characters/granny-rita/">Can’t-Hear-Anything granny</a>” in a number of episodes.</p> <p>In <a href="https://www.tandfonline.com/doi/full/10.1080/14992027.2024.2418970">our research</a>, people with hearing loss reported feeling embarrassment, shame, frustration, sadness and fatigue from trying to manage their hearing difficulties during everyday conversations.</p> <p>In the results of <a href="https://www.tandfonline.com/doi/full/10.1080/14992027.2023.2293651">a survey</a> currently under peer review, almost two-thirds felt other people laughed about or treated their hearing loss as a joke, often making them feel uncomfortable.</p> <p>An example <a href="https://www.tandfonline.com/doi/full/10.1080/14992027.2024.2389189">of this teasing</a> can be seen in a real-life conversation we recorded with a grandfather with hearing loss and his extended family while having afternoon tea.</p> <p>After the older man has ongoing trouble hearing his granddaughters, his wife teases him with the question “You got your hearing aids in Grandpa?”, which receives laughter from his son and granddaughters.</p> <p>While this sort of teasing might seem light-hearted, it can cause someone with hearing loss to feel embarrassed when they have trouble hearing.</p> <p>A key finding from <a href="https://www.tandfonline.com/doi/full/10.1080/14992027.2024.2406885">our interview research</a> was that adults with hearing loss respond to experiences of stigma by not telling others about their hearing loss.</p> <p>Similarly, in an international <a href="https://www.tandfonline.com/doi/full/10.1080/14992027.2023.2293651">survey of 331 adults</a> with hearing loss, the results of which are yet to be published in a peer-reviewed journal, one in four had not told anyone about their hearing loss. Others only told certain people in specific circumstances.</p> <p>There might, therefore, be family and friends at your Christmas gatherings facing the challenges of hearing loss without anyone knowing.</p> <h2>Supporting loved ones with hearing loss this Christmas</h2> <p>For adults with hearing loss, experiences of stigma can cause them to start to withdraw from social situations, participate less in conversations, and become more <a href="https://journals.lww.com/psychosomaticmedicine/abstract/2013/02000/social_isolation_and_loneliness__relationships.9.aspx">socially isolated and lonely</a>.</p> <p>But a greater awareness about hearing loss and inclusive communication can help tackle the stigma. Here are some simple ways you can be more inclusive of people with hearing loss this festive season:</p> <ol> <li> <p>Think about the location of your event – how noisy is it? When possible, choose restaurants and social settings that are quieter. Outdoor settings will generally be less noisy than indoor ones (apps such as <a href="https://theambientmenu.com.au/">The Ambient Menu</a> can help you choose).</p> </li> <li> <p>Turn down background noise if you can (for example, TV, radio, music).</p> </li> <li> <p>Speak face-to-face as much as possible. This allows for lip-reading so that people are not just reliant on their hearing. If you know someone has difficulty hearing, move closer to them and talk clearly and slightly more slowly.</p> </li> <li> <p>Arrange seating in a way that allows everyone to face each other. Round tables are best.</p> </li> <li> <p>Give people the opportunity to choose where they are seated around a table or in a restaurant. Adults with hearing loss may position themselves in the middle of a table or next to specific people they need to hear.</p> </li> <li> <p>If you are at an event with speeches, use a microphone when possible.</p> </li> <li> <p>If you notice a person not joining in the conversation you could ask them if they can hear OK and, if not, what you can do to help.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/245943/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> </li> </ol> <p><em><a href="https://theconversation.com/profiles/katie-ekberg-1534998">Katie Ekberg</a>, Senior Lecturer, College of Nursing and Health Sciences, <a href="https://theconversation.com/institutions/flinders-university-972">Flinders University</a> and <a href="https://theconversation.com/profiles/louise-hickson-2280688">Louise Hickson</a>, Professor of Audiology, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Awkwardness can hit in any social situation – here are a philosopher’s 5 strategies to navigate it with grace

<p><em><a href="https://theconversation.com/profiles/alexandra-plakias-1512990">Alexandra Plakias</a>, <a href="https://theconversation.com/institutions/hamilton-college-2966">Hamilton College</a></em></p> <p>The holidays offer many opportunities for awkward moments. Political discussions, of course, hold plenty of potential. But any time opinions differ, where estrangements have caused lingering rifts, or when behaviors veer toward the inappropriate, awkwardness can set in.</p> <p>Awkwardness is what happens in social interactions when you suddenly find yourself without a script to guide you through. Maybe the situation is new or catches you off guard. Maybe you don’t know what’s expected of you, or you aren’t sure what role you’re playing in the social drama around you. It’s characterized by feelings of self-consciousness, uncertainty and discomfort.</p> <p>As a <a href="https://scholar.google.com/citations?user=vyBxhaQAAAAJ&amp;hl=en&amp;oi=ao">philosopher who studies moral psychology</a>, I’m interested in awkwardness because I wanted to understand the ways social discomfort stops people from engaging with difficult topics and challenging conversations. Awkwardness seems to inhibit people, even when their moral values suggest they should speak up. But it has a positive role to play, too – it <a href="https://www.collectiveinkbooks.com/zer0-books/our-books/awkwardness">can alert people to areas where their social norms are lacking</a> or outdated.</p> <p>People often blame themselves when things take a turn toward the awkward. But awkwardness is really a collective failure – people aren’t awkward, situations are. And they become awkward because you don’t have the resources to navigate your way through tricky social situations.</p> <p>Awkwardness is often confused with embarrassment, but the two are different in important ways, and so are their remedies. Embarrassment is a response to <a href="https://www.jstor.org/stable/2772920">a personal failing or gaffe</a>, and the <a href="https://greatergood.berkeley.edu/article/item/born_to_blush">right response is to acknowledge it, own it and move on</a>. Because awkwardness is caused by a lack of social guidance, you can try to anticipate and head it off before it happens, or you can respond to it by trying to develop better or clearer social scripts to help you – and others – navigate similar situations in the future.</p> <p>After researching and writing an entire <a href="https://doi.org/10.1093/oso/9780197683606.001.0001">book on awkwardness</a>, I’ve come to the conclusion that it’s not something we can – or should – avoid altogether. But there are a few strategies people can use to minimize awkwardness and deal with it when it does, inevitably, happen.</p> <h2>1. Know your goals, know your roles</h2> <p>Uncertainty is the oxygen of awkwardness. Before you engage in a potentially awkward or contentious interaction, ask yourself: What do I want to get out of this?</p> <p>When you’re clear on your goals for the interaction, not only are you better able to perform your role in it, but you’re also giving clearer signals to others, helping them perform their roles in the unfolding social drama.</p> <p>So, if you’re worried it’ll be awkward when your uncle starts in on his annual political rant, think about what you want the outcome to be. Do you want to convince him he’s wrong? Unlikely to happen. Do you want other family members to feel less anxious? Do you want your own views to be heard?</p> <p>I’m not suggesting that some forethought will make things go smoothly or guarantee that no one’s feelings will be hurt. But it will help you feel more confident in your ability to navigate toward your desired outcome.</p> <h2>2. There’s no ‘I’ in awkward</h2> <p><a href="https://doi.org/10.1177/1368430212441637">Awkward situations</a> breed <a href="https://doi.org/10.1080/14780887.2010.500357">intense self-consciousness</a>. This is both uncomfortable and counterproductive. By focusing on yourself, you’re not attuned to the people around you or the signals they’re sending – signals that could offer you a pathway out of the awkward situation. So make sure you’re paying attention to the other players in the drama, not just your own discomfort.</p> <h2>3. Plan, coordinate and be explicit</h2> <p>People do so much planning in other areas of their lives, yet they expect social interactions to just flow effortlessly. But like a vacation or a hike in the woods, sometimes a conversation goes better when you approach it with a map. Have some go-to topics or questions at hand.</p> <p>And you don’t have to go it alone. If you’re worried about broaching a sensitive topic, or interacting with a particularly prickly guest, coordinate with a friend or relative.</p> <p>If you expect to see someone with whom you have an unresolved relationship – an estranged family member, an old friend you ghosted – try to do some prep work in advance. Emails or letters can give people a chance to process reactions without putting them on the spot.</p> <p>Even having a scripted activity on deck can make things less awkward. It doesn’t have to be anything formal, like a board game. Just keep some tasks available for guests who might otherwise lurk uncomfortably – like shaking up the salad dressing or putting forks on the table.</p> <h2>4. Laugh it off</h2> <p>If, despite your best efforts, awkwardness does strike, offer people a way out – they’ll probably grab it. This doesn’t need to be momentous; it could be a little joke, a small-talk topic, or even – and only if things get very desperate – knocking a spoon off the table to break the silence.</p> <h2>5. Consider the alternatives</h2> <p>These strategies might help you avoid awkwardness. But take a moment to consider whether you really want to. Awkwardness is the result of social uncertainty; it slows things down and curbs your confidence.</p> <p>In its absence, other emotions can set in. Having things out in the open can be a relief, but it can also lead to anger, sadness and other feelings that might best be saved for another occasion.</p> <p>So if things are awkward, it’s worth looking around to see what role that awkwardness is playing, and what might take its place if it’s gone.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/244107/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/alexandra-plakias-1512990">Alexandra Plakias</a>, Associate Professor of Philosophy, <a href="https://theconversation.com/institutions/hamilton-college-2966">Hamilton College</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

‘Is this all there is?’ Retirement can be a painful transition if we don’t adjust our thinking

<p><em><a href="https://theconversation.com/profiles/susan-moore-1446031">Susan Moore</a>, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a></em></p> <p>The age at which Australians can receive the pension has <a href="https://www.dss.gov.au/seniors/benefits-payments/age-pension">risen to 67</a>, meaning many of us are working longer. But the length of time we are expected to spend retired has also risen, because <a href="https://www.abs.gov.au/statistics/people/population/life-expectancy/latest-release">we are living longer</a>.</p> <p>It’s not unreasonable to expect the retirement phase will last about 20 years, perhaps longer. How should people approach it?</p> <h2>Are retirees satisfied?</h2> <p>In 2018 a colleague and I <a href="https://www.routledge.com/Women-and-Retirement-Challenges-of-a-New-Life-Stage/Moore-Rosenthal/p/book/9781138045231">surveyed nearly 1,000 Australians</a> aged 55 and over who described themselves as fully or substantially retired from the workforce.</p> <p>Most were very satisfied (51%) or satisfied (35%) with their retirement, and the majority rated their post-retirement life satisfaction as better (47%) or the same (39%) as it had been when they were working.</p> <h2>What do retirees like most?</h2> <p>Retirees in our survey talked about freedom. Freedom to sleep in, travel, catch up with friends and family, renovate, garden, get fit, try art classes, learn Italian and if they can afford it, spend up big.</p> <p>But even freedom can have a downside. One woman from the survey said after four months she got sick of it, asking “Is this all there is?”</p> <p>So what did retirees miss most? Money was a big issue for nearly 20%, and about one-third felt their financial position had worsened, even though the group had mainly worked in professional and white-collar jobs.</p> <p>But the things they missed most were social – the opportunity to make new friends, to engage in new activities, and to feel useful. They said things like:</p> <blockquote> <p>I miss the companionship of working in a team. Miss some of the social connections that I once enjoyed.</p> </blockquote> <p>Work not only provides income and social contact, it also has the capacity to engender a sense of meaning and purpose. Some retirees commented specifically on this</p> <blockquote> <p>I miss the sense of purpose. While it was hugely stressful, I felt useful. Now I keep feeling at a bit of a loss as if I should be doing something.</p> </blockquote> <h2>Identity loss</h2> <p>There’s also the issue of <a href="https://www.taylorfrancis.com/books/mono/10.4324/9780203786338/marienthal-marie-jahoda-paul-lazarsfeld-hans-zeisel">identity loss</a>. Work provides us with status; it enhances our sense of self. Achievement of work goals can build confidence and self-esteem.</p> <p>When we meet a new person, often the first question they ask is “what do you do for a living?” It can feel as though your work defines you as a person, rather than your many-faceted self.</p> <p>Not surprisingly, our study respondents frequently commented on retirement as challenging their sense of identity.</p> <h2>The retirement journey</h2> <p>So it is important to remember retirement is not just an event, it’s a process.</p> <p>In any <a href="https://onlinelibrary.wiley.com/doi/abs/10.1002/j.2161-1920.2011.tb01102.x">major life transition</a>, it’s necessary to adapt our roles and expectations. Even the most exciting life changes, such as becoming a parent or winning a lottery, involve psychological work.</p> <p>We are likely to experience strong emotions, both positive and negative, as we experiment, fail, lose heart, try something else and eventually adjust to a new reality.</p> <p>These adjustments might be greater for retirees who go from full-time work to full-time leisure, than for those who move gradually through part-time or casual work or who quickly take up new activities they’ve been planning for years.</p> <p>Mark Cussen, a financial planner specialising in retirement, argues the retirement journey takes us through <a href="https://www.investopedia.com/articles/retirement/07/sixstages.asp">several psychological stages</a>, including a honeymoon phase in which new retirees feel relieved as the constraints of working life are removed.</p> <p>However, the initial sense of freedom loses its novelty value. Some retirees then go through a phase of disenchantment. Life can feel boring, lacking in purpose or weighed down by domestic duties and activities that do not challenge or bring joy.</p> <h2>The ‘best years of our lives’</h2> <p>The final phase is adaptation, involving a re-orientation of identity from worker to someone who finds meaning and purpose in a different set of activities.</p> <p>This change usually involves renegotiating relationships with family and friends as well as experimenting with new activities, interests and friendship groups.</p> <p>Over time, most retirees develop a new, non-work identity. New routines, different social worlds and re-imagined goals are established. Many describe these years as the best of their lives.</p> <h2>What makes a successful retirement?</h2> <p>Research <a href="https://academic.oup.com/workar/article-abstract/2/2/262/2428266?login=false">assessing the strongest predictors</a> of adjustment to and satisfaction with retirement is complex because there are so many potential variables to be measured and controlled.</p> <p>But these are often distilled down to several key factors including physical health, finances, psychological health, leisure activities, and social integration.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/21463050/">Studies assessing gender difference</a> in adjustment to retirement are equivocal, but somewhat dated. Nevertheless, <a href="https://www.researchgate.net/publication/228590652_Renegotiating_identity_and_relationships_Men_and_women's_adjustments_to_retirement">many commentators agree</a> women generally have fewer problems adapting socially.</p> <p>Women tend to have stronger non-work networks, are more integrated into their communities and have a more multifaceted sense of identity than those men who define themselves largely in terms of their work.</p> <p>However, the average woman is <a href="https://www.routledge.com/The-Psychology-of-Retirement/Rosenthal-Moore/p/book/9780815347088?srsltid=AfmBOoo--YAKvrHK8gDkQ0Cd1qI7A0PHOjgEZ-VqzDRAJb4KvEt5eMpt">less financially prepared</a> for retirement than a man as a result of taking time off work for children or other caring responsibilities. Women also dominate many of the lower paid jobs.</p> <p>But for both sexes, <a href="https://academic.oup.com/workar/article-abstract/2/2/262/2428266">studies indicate</a> pre-retirement planning helps ensure a secure retirement.</p> <h2>Work out what’s important</h2> <p>Money isn’t everything. Lifestyle planning including post-retirement activities, new roles and interests,prioritising mental and physical health and maintaining your social contacts are also vital aspects of a workforce exit strategy.</p> <p>How are you planning to stay mentally stimulated? What strategies do you have in place to manage stress and maintain good physical health? And what about friendships? Loneliness is being <a href="https://www.mja.com.au/journal/2024/221/6/loneliness-epidemic-holistic-view-its-health-and-economic-implications-older-age">described as an “epidemic”</a> among the elderly, especially those without a partner.</p> <p>How will you build a new social life that may include but does not rely on former work colleagues? How will you negotiate a family life that keeps you connected without becoming a domestic slave?</p> <h2>A well-planned retirement</h2> <p>Retirement has the potential to be a wonderful phase of life in which it is possible to strengthen relationships and achieve goals that you didn’t have time for in your middle years when you were consolidating your career and home life.</p> <p>It’s a time to live out some of your dreams, work through a bucket list perhaps, and have some fun as well as planning what sort of legacy you will leave for future generations.</p> <p>What’s the secret? In short, plan your finances, maintain a healthy lifestyle, stay socially integrated, challenge yourself mentally, stay positive and be flexible.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/241265/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/susan-moore-1446031"><em>Susan Moore</em></a><em>, Emeritus Professor, Faculty of Health, Arts and Design, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

The anatomy of a hot flush – and whether it can really make your head steam

<p><em><a href="https://theconversation.com/profiles/michelle-spear-172043">Michelle Spear</a>, <a href="https://theconversation.com/institutions/university-of-bristol-1211">University of Bristol</a></em></p> <p>A hot flush is a phenomenon as disruptive as it is commonplace. One moment, life proceeds as usual. The next, a wave of heat rises, spreading from the chest to the face – leaving behind flushed skin and beads of sweat. For many, this sudden warmth is accompanied by an <a href="https://www.mayoclinic.org/diseases-conditions/hot-flashes/symptoms-causes/syc-20352790">accelerated heartbeat and a faint sense of unease</a>. Though brief – typically lasting anywhere from 30 seconds to five minutes – its intensity can be startling and made worse by unpredictable timing.</p> <p>A recent viral video has brought attention to just how intense a hot flush can be. The video depicts a woman named Tracey Monique <a href="https://uk.style.yahoo.com/menopause-hot-flush-flash-symptoms-134536113.html?guccounter=1">experiencing a hot flush</a> while at an outdoor event. In the video, her head is literally steaming.</p> <p>The sight of wisps of vapour escaping her head highlighted the dramatic effects of this common <a href="https://www.nhs.uk/conditions/menopause/symptoms/">perimenopausal symptom</a>. Often misunderstood or trivialised, the image of a hot flush brings fresh attention to a phenomenon that affects an estimated <a href="https://www.hopkinsmedicine.org/health/conditions-and-diseases/introduction-to-menopause">75% of people experiencing perimenopause</a>.</p> <p>The video has also sparked debate on social media – reflecting the complexity of hot flushes themselves. Some argue the steam escaping Monique’s head was caused by her removing her hat while being in the cold. But many women have commented, saying the video perfectly encapsulates what a hot flush feels like.</p> <p>Let’s take a look at what’s actually happening during a hot flush and why they can feel so severe.</p> <h2>Hormonal instigators</h2> <p>At the heart of a hot flush lies oestrogen – a hormone critical role in regulating body temperature in women. Oestrogen directly <a href="https://my.clevelandclinic.org/health/body/22566-hypothalamus">influences the hypothalamus</a>, a small but essential structure in the brain often referred to as the <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC6397692/">body’s thermostat</a>. The hypothalamus monitors and adjusts body temperature to maintain balance.</p> <p>Under normal circumstances, the hypothalamus keeps the body within a narrow temperature range – adjusting blood flow and sweat production as needed. But during perimenopause, <a href="https://www.rcog.org.uk/for-the-public/browse-our-patient-information/treatment-for-symptoms-of-the-menopause/?utm_source=chatgpt.com">oestrogen levels fluctuate</a> unpredictably and eventually decline. These hormonal shifts disrupt the hypothalamus’s ability to maintain its usual set temperature.</p> <p>Declining oestrogen levels also make the hypothalamus overly sensitive to small changes in body temperature – misinterpreting these as <a href="https://pubmed.ncbi.nlm.nih.gov/31001050/">signs of overheating</a>. This triggers an exaggerated response aimed at cooling the body down: a hot flush. The result is a sudden dilation of blood vessels, particularly in the skin of the upper body, to allow heat to radiate outward. Simultaneously, sweat glands activate – intensifying the sensation of heat.</p> <p><a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC3956631/">Luteinising hormone</a>, which primarily regulates ovulation, also plays a secondary role in hot flushes. As oestrogen levels decline, the pituitary gland (which regulates key hormones that control growth, reproduction and metabolism) <a href="https://academic.oup.com/endo/article/163/2/bqab268/6490154">releases erratic surges</a> of lutenising hormone. These spikes appear to further heighten the hypothalamus’s sensitivity, amplifying its misinterpretation of normal body temperature as overheating.</p> <h2>The cooling response</h2> <p>During a hot flush the hypothalamus sends urgent signals to the autonomic nervous system, which governs involuntary functions such as heart rate, blood pressure and sweating. This prompts blood vessels near the skin to dilate – a <a href="https://www.ncbi.nlm.nih.gov/books/NBK557562/">process called vasodilation</a>. This allows more blood to flow to the surface to release heat. This is why the face, neck and chest can feel intensely warm and look visibly flushed during a hot flush.</p> <p>Almost simultaneously, the hypothalamus activates sweat glands in the upper body. Sweating is meant to <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC6773238/">cool the body</a> through evaporation. In cold environments, this sweat may produce visible steam – as seen in Monique’s viral video.</p> <p>But once the hypothalamus realises the body isn’t actually overheated, vasodilation subsides and blood vessels return to their normal state. But the rapid cooling effect from sweating can leave women <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC4612529/">feeling chilled</a>. This creates a rollercoaster of sensations during and after the hot flush.</p> <p>This sequence – heat, flush, sweat and chill – reflects the body’s struggle to regain equilibrium in response to a misfiring thermostat.</p> <h2>The debate</h2> <p>While the sensation of heat is undeniable, whether hot flushes significantly raise skin temperature remains debated.</p> <p><a href="https://www.maturitas.org/article/0378-5122(79)90009-4/abstract">Thermographic studies</a>, which use infrared imaging to measure heat patterns and surface temperature, have demonstrated measurable skin temperature rises – particularly in the face, neck and chest.</p> <p>But other research has found only <a href="https://www.obgproject.com/2019/07/24/are-menopausal-hot-flushes-really-triggered-by-core-temperature/">minor or negligible changes</a> in skin temperature. This raises questions about whether the perception of heat correlates directly with physiological changes.</p> <p>Critics suggest that the sensation of heat stems more from the brain’s altered thermoregulation than from actual warming of the skin. Tools such as thermographic imaging may also miss subtle or transient temperature changes – or these changes may be masked by sweat evaporation.</p> <p>It may also be the case that <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC4612529/">skin temperature changes</a>, like other perimenopausal symptoms, vary widely between people. The <a href="https://bmcwomenshealth.biomedcentral.com/articles/10.1186/1472-6874-9-13">variability in oestrogen levels</a> contributes significantly – with those experiencing more erratic hormonal changes often reporting more intense or frequent flushes. Factors such as <a href="https://www.mdpi.com/2072-6643/16/5/655">genetics, lifestyle and environmental triggers</a>, all add to the diversity of experiences and how intense symptoms might be.</p> <p>Hot flushes are a complex interplay of hormonal, neurological and vascular responses. While the scientific debate about skin temperature changes remains unresolved, the lived experience of heat and discomfort is undeniable. For many, these symptoms are disruptive and even debilitating, profoundly affecting daily life.</p> <p>Monique’s viral video, with the striking image of steam rising from her head, has resonated deeply with countless women – offering stark visual evidence of what they’ve felt but often struggled to articulate. Understanding the anatomy of a hot flush not only sheds light on its mechanisms but also underscores the importance of empathy and tailored approaches to managing this multifaceted symptom.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/244452/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/michelle-spear-172043">Michelle Spear</a>, Professor of Anatomy, <a href="https://theconversation.com/institutions/university-of-bristol-1211">University of Bristol</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

A brief history of Christmas Pudding – and why it can actually be quite good for you

<p><em><a href="https://theconversation.com/profiles/hazel-flight-536221">Hazel Flight</a>, <a href="https://theconversation.com/institutions/edge-hill-university-1356">Edge Hill University</a></em></p> <p>Even in these hard and strange times, Christmas will be celebrated and traditions upheld. And for many British households, Christmas dinner would not be complete without a Christmas pudding – traditionally served with brandy sauce, brandy butter or custard.</p> <p>The Christmas pudding originated in the <a href="http://medievalcookery.com/recipes/frumenty.html">14th-century</a> as a sort of porridge, originally known as “<a href="http://cookit.e2bn.org/historycookbook/1116-frumenty.html">frumenty</a>”, which bears little resemblance to the dessert we know today.</p> <p>It was <a href="https://historydollop.com/2020/03/15/frumenty-a-medieval-wheat-porridge/">originally made</a> with hulled wheat, boiled in milk, seasoned with cinnamon and coloured with saffron. It was associated with meatless days, lent and advent and was often served as a plain dish. But there are a <a href="https://www.epersianfood.com/frumenty/">variety of recipes</a> which included <a href="https://www.mumwhatelse.com/christmas-pudding-traditional-recipe/s">additions</a> such as beef, mutton, raisins, currants, prunes, wines and spices.</p> <p>In some instances, this was the staple food for Christmas eve, although in Yorkshire it was eaten first thing <a href="https://www.gutenberg.org/files/19098/19098-h/19098-h.htm">on Christmas morning</a>. In the 17th-century changes to the recipe were made. It was thickened with eggs, breadcrumbs, dried fruit and beer or spirits were added – and came to resemble something a bit more like a sweet pudding. However, it was the Victorians who fine tuned the recipe into the <a href="http://www.bbc.co.uk/shropshire/content/articles/2005/12/07/christmas_pudding_recipe_feature.shtml#:%7E:text=Brandy%20Sauce&amp;text=This%20stew%20was%20served%20as,to%20give%20the%20pudding%20richness">Christmas pudding</a> many of us enjoy today.</p> <p>A Christmas pudding should have 13 ingredients – that represent Jesus and the 12 disciples. Traditionally, these ingredients include: raisins, currants, suet, brown sugar, breadcrumbs, citron, lemon peel, orange peel, flour, mixed spices, eggs, milk and brandy. Brandy is also <a href="https://www.pudforallseasons.com.au/blog/christmas-pudding-history-and-traditions">traditionally</a> poured over the pudding and set alight. The flaming brandy is said to represent the passion of Christ.</p> <p>Christmas puddings were traditionally boiled in a “pudding cloth”, although today are usually steamed in a bowl. Presented on the table with a sprig of holly, they are then doused in brandy and set alight.</p> <p>The last Sunday before Advent became known as “<a href="https://www.goodhousekeeping.com/uk/christmas/christmas-countdown/a550045/ultimate-stir-up-sunday-when/">stir up Sunday</a>”. This was when the ingredients of the pudding would be assembled and stirred up in a bowl with a wooden spoon (representing the manger) from east to west – symbolising the journey taken by the three wise men. Traditionally, every family member stirs the pudding three times and makes a secret wish.</p> <p>Trinkets were always included in the traditional pudding. As a child I still remember the excitement of waiting to see who was going to <a href="https://metro.co.uk/2016/12/16/why-do-people-put-money-in-christmas-puddings-6327772/">find the sixpence</a>. Whoever found the coin was believed to have good fortune over the coming year.</p> <h2>A healthy pud?</h2> <p>Although the Christmas holidays can sometimes feel a little unhealthy – with a lot of sitting around and excessive food consumption – the ingredients that makeup a Christmas pudding are actually <a href="https://www.express.co.uk/life-style/health/365596/Why-Christmas-pudding-is-good-for-you">pretty nutritious</a>.</p> <p>Traditional Christmas puddings consists of fibre rich ingredients, such as fruits, nuts and currants. Dried fruits are rich in fibre, enzymes, polyphenols (substances with a <a href="https://www.ijmrhs.com/medical-research/dry-fruits-and-diabetes-mellitus.pdf">high antioxidant activity</a>), vitamins and minerals. <a href="https://www.bbc.co.uk/food/recipes/christmaspudding_71054">Sultanas, currants, apricots</a> and <a href="https://www.goodhousekeeping.com/uk/food/recipes/a557006/pear-and-ginger-pudding">pears</a> are highly nutritious and packed with <a href="https://www.webmd.com/diet/foods-rich-in-potassium">essential potassium and iron</a>. And although dried fruits can contain a lot of sugar, they have a lower glycemic index value so don’t impact your blood sugar in the same way as other sweet treats.</p> <p>Raisins are also rich in antimicrobial compounds, fibre and iron. These compounds lower the risk of heart disease and can relieve constipation. Prunes too can also aid with digestion, relieve constipation, reduce inflammation and protect cells from free radical damage.</p> <p>Walnuts, hazelnuts, pecans and almonds can also be added into the mix and these all come with a range of <a href="https://www.healthline.com/nutrition/benefits-of-walnuts">health benefits</a> – from <a href="https://www.nhs.uk/news/food-and-diet/nuts-may-lower-cholesterol/">lowering cholesterol levels</a> and reducing heart disease risk to delivering high levels of vitamin E, polyphenols and melatonin.</p> <p>The mixed spices, cinnamon, ginger, cloves, pimentos (or all spice) in a Christmas pudding are also an incredible source of <a href="https://food.ndtv.com/food-drinks/health-benefits-of-38-important-spices-from-around-the-world-1811783">aromatic antioxidants</a>. Spices aid digestion and have anti-inflammatory and anti-bacterial properties. They can supposedly even help to reduce bloating, cramps and nausea – key if you’ve been overdoing it a bit.</p> <p>There is one secret ingredient often overlooked but included in many recipes – <a href="https://www.lovefood.com/recipes/56899/christmas-pudding-recipe">the carrot</a>. Rich in beta-carotene, which the body utilises to produce Vitamin A, carrots are good for lowering cholesterol levels and, yes, for the health of your eyes.</p> <h2>A global tradition</h2> <p>Although a British tradition, the Christmas pudding is eaten in various countries including <a href="https://theconversation.com/how-christmas-pudding-evolved-with-australia-35027#:%7E:text=The%20Christmas%20pudding%20was%20there,usual%20rations%20at%20Christmas%20time">Australia</a> and <a href="https://www.foodandhome.co.za/recipes/karoo-steamed-christmas-pudding">South Africa</a>. The Canadians also have a version which includes <a href="https://cannedpeachesproject.com/canadian-christmas-pudding-recipe/">potatoes alongside the carrots</a>.</p> <p>The Christmas pudding even makes its way into literature, with Charles Dickens’ Christmas Carol making <a href="https://www.inliterature.net/food-in-literature/baked-goods/cakes/2012/12/a-christmas-carol-steamed-christmas-pudding.html">reference to it</a>. Then there is the case for Agatha Christie’s Hercule Poirot to solve in which he is advised to avoid the <a href="https://www.agathachristie.com/stories/the-adventure-of-the-christmas-pudding">plum pudding</a> – another name for the Christmas pud.</p> <figure><iframe src="https://www.youtube.com/embed/IFKJJVzRvGI?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>One well known fact about the Christmas pudding is that there always seems to be some left over after Christmas day. In fact Christmas puddings of the past could last up to a year, so it was often shared out. Indeed, in 1885 a British newspaper reported the joyful consumption of a <a href="http://www.chinovalleyaz.net/DocumentCenter/View/5620/December-2019-Senior-Sentinel">plum pudding</a> – sent overland via special envoy from Tehran — to a group of British soldiers stationed in northwestern Afghanistan.</p> <p>If you don’t fancy posting a pudding there are a number of ways you can share and use the <a href="https://www.bbcgoodfood.com/howto/guide/10-ways-leftover-christmas-desserts">leftovers</a> – with a whole host of recipes from Christmas strudel to a black pudding breakfast replacement.

Ant stings can be painful. Here’s how to avoid getting stung this summer (and what to do if you do)

<p><em><a href="https://theconversation.com/profiles/sam-robinson-2237268">Sam Robinson</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a></em></p> <p>With the start of summer just days away, many of us will be looking forward to long sunny days spent at the beach, by the pool, out camping or picnicking in the park.</p> <p>Insects also love summer. This is when most of them <a href="https://www.australiangeographic.com.au/topics/science-environment/2016/12/experts-predict-increased-insect-activity-this-summer/">breed and feed</a>. But this shared appreciation of the season can sometimes lead to conflict.</p> <p>Insects have long been prey to many species, including birds, mammals, amphibians and other insects. As such, they’ve evolved a diverse range of defences – perhaps none more familiar to humans than the sting.</p> <p>Many ants have a sting at their rear end which they use to deliver venom. It’s not the sting itself that causes pain, but rather <a href="https://www.nature.com/articles/s41467-023-38839-1">the venom</a>. Ant venom contains a cocktail of different chemicals, some of which have evolved specifically to manipulate nerve endings in our skin to cause pain.</p> <p>Let’s look at some of the different ant stings you might experience this summer in Australia, and how to respond.</p> <h2>Bull ants</h2> <p>Bull ants (also known as bulldog ants, jumper ants, or jack jumpers) are large, for an ant. Some species can reach a length of <a href="https://en.wikipedia.org/wiki/Myrmecia_(ant)#:%7E:text=Each%20of%20their%20eyes%20contains,mm%20(1.5%20in)%3B%20M.">4 centimetres</a>. They are easily recognisable with their large eyes, long mandibles (jaws) and aggressive nature.</p> <p>Their sting is immediate, hot, sharp, and unmistakable, not dissimilar to that of a honeybee. The intense pain will last only a few minutes, before it’s replaced by some redness and swelling around the sting site.</p> <h2>Green-head ants</h2> <p>Green-head ants are also called green ants (but not to be confused with the <a href="https://en.wikipedia.org/wiki/Oecophylla_smaragdina">green tree ants</a> of northern Australia which do not sting). Green-head ants are common, and love our grass lawns.</p> <p>At around <a href="https://en.wikipedia.org/wiki/Green-head_ant">6 millimetres long</a>, they are significantly smaller than bull ants. They can be recognised by their shiny green and purple exoskeleton.</p> <p>Green-head ants tend to be less aggressive than bull ants, but they can still deliver a meaningful sting. The pain of a green-head ant’s sting can build more gradually, and create an intense, sticky ache.</p> <h2>Fire ants</h2> <p>Fire ants (or red imported fire ants) are originally from South America. They were first detected <a href="https://www.fireants.org.au/stop/how-fire-ants-arrived-in-australia">in Brisbane in 2001</a>, thought to have hitched a ride in shipping containers, and have since spread across south-east Queensland.</p> <p>Fire ants are reddish-brown and black and range in size from <a href="https://www.fireants.org.au/look/appearance">2–6 millimetres long</a>.</p> <p>You’re most likely to encounter fire ants at their nests, which look like a pile of powdery soil. A fire ant nest doesn’t have an obvious entry, which is a good way to distinguish them from other similar ant nests.</p> <p>Disturbing a fire ant nest will awaken an angry mass of hundreds of ants and put you at risk of being stung.</p> <p>The initial pain from an individual sting is like an intense, hot itch, though manageable. But fire ant stings rarely occur in single digits. One ant can sting multiple times, and multiple ants can sting one person, which can lead to <a href="https://theconversation.com/fire-ants-are-on-the-march-heres-what-happens-when-they-sting-218908">hundreds of stings</a>. Fire ant stings can lead to pus-filled ulcers and scarring in the days afterwards.</p> <p>If you live in an area where there are fire ants, it’s worth taking a few minutes to educate yourself on how to <a href="https://www.fireants.org.au/look">recognise and report</a> them.</p> <h2>Electric ants</h2> <p><a href="https://www.antwiki.org/wiki/Wasmannia_auropunctata">Electric ants</a> are another nasty accidental import, originally from Central and South America. Currently restricted to <a href="https://www.outbreak.gov.au/current-outbreaks/electric-ants">Cairns and surrounds</a>, these are tiny (1.5 millimetres long) yellow ants.</p> <p>Like fire ants, these ants will typically defend <em>en masse</em>, so many will sting at once. Their sting is more painful than you’d expect from such a tiny creature. I liken it to being showered in red hot sparks.</p> <p>If you think you see electric ants, you should report this to <a href="https://www.business.qld.gov.au/industries/farms-fishing-forestry/agriculture/biosecurity/animals/invasive/restricted/electric-ant">Biosecurity Queensland</a>.</p> <h2>Aussie ants aren’t the worst</h2> <p>You might be surprised to hear Australian ants don’t even make the podium for the most painful ant stings. Among the prize winners are <a href="https://www.press.jhu.edu/books/title/10878/sting-wild">harvester ants</a> (North and South America) which cause an extreme, sticky ache, likened to a drill slowly turning in your muscle – for as long as 12 hours.</p> <p>The gold medal goes to the sting of the bullet ant of South and Central America, which <a href="https://www.press.jhu.edu/books/title/10878/sting-wild">has been described</a> as:</p> <blockquote> <p>Pure, intense, brilliant pain. Like walking over flaming charcoal with a 3-inch nail embedded in your heel.</p> </blockquote> <h2>How to avoid getting stung (and what to do if you do)</h2> <p>Fortunately, the solution is usually very simple. Look before you sit on the ground or lay out your picnic blanket, avoiding areas where you see ant nests or lots of foraging ants.</p> <p>Choice of footwear can also be important. In my experience, perhaps unsurprisingly, most stings occur on thong-wearing feet.</p> <p>If you do get stung, in most cases it’s going to get better on its own. Pain will usually subside after a few minutes (sometimes a little longer for a green-head ant sting). The redness, swelling and itch that typically follow can last for a few days.</p> <p>In the meantime, if needed, <a href="https://www.healthdirect.gov.au/insect-bites-and-stings">an ice pack</a> will help with the pain. If it’s particularly bad, a local anaesthetic cream containing lidocaine may offer some temporary relief. You can get this over the counter at the pharmacy.</p> <p>A small proportion of people may have an allergic reaction to ant stings. In very severe cases this might involve <a href="https://www.healthdirect.gov.au/insect-bites-and-stings#anaphylaxis">trouble breathing</a> or swallowing. If you or someone you’re with experiences these symptoms after an ant sting, seek urgent medical attention.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/241582/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/sam-robinson-2237268">Sam Robinson</a>, Senior Research Fellow, Institute for Molecular Bioscience, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

7 things you can do if you think you sweat too much

<p><em><a href="https://theconversation.com/profiles/michael-freeman-223922">Michael Freeman</a>, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a></em></p> <p>Sweating is our body’s way of cooling down, a bit like an internal air conditioner.</p> <p>When our core temperature rises (because it’s hot outside, or you’re exercising), sweat glands all over our skin release a watery fluid. As that fluid evaporates, it takes heat with it, keeping us from overheating.</p> <p>But sweating can vary from person to person. Some people might just get a little dewy under the arms, others feel like they could fill a swimming pool (maybe not that dramatic, but you get the idea).</p> <p>So what’s a normal amount of sweat? And what’s too much?</p> <h2>Why do some people sweat more than others?</h2> <p>How much you sweat depends on a number of <a href="https://www.tandfonline.com/doi/pdf/10.1080/23328940.2019.1632145">factors</a> including:</p> <ul> <li> <p>your age (young kids generally sweat less than adults)</p> </li> <li> <p>your sex (men tend to sweat more than women)</p> </li> <li> <p>how active you are.</p> </li> </ul> <p>The average person sweats at the rate of <a href="https://www.tandfonline.com/doi/pdf/10.1080/23328940.2019.1632145">300 millilitres per hour</a> (at 30°C and about 40% humidity). But as you can’t go around measuring the volume of your own sweat (or weighing it), doctors use another measure to gauge the impact of sweating.</p> <p>They ask whether sweating interferes with your daily life. Maybe you stop wearing certain clothes because of the sweat stains, or feel embarrassed so don’t go to social events or work.</p> <p>If so, this is a medical condition called <a href="https://www.dermcoll.edu.au/atoz/axillary-hyperhidrosis/">hyperhidrosis</a>, which affects <a href="https://onlinelibrary.wiley.com/doi/pdf/10.1111/1346-8138.16908">millions of people</a> worldwide.</p> <p>People with this condition most commonly report problematic armpit sweating, as you’d expect. But sweaty hands, feet, scalp and groin can also be an issue.</p> <p>Hyperhidrosis can be a symptom of another medical condition, such as an <a href="https://www.frontiersin.org/articles/10.3389/fendo.2023.1167890/pdf">overactive thyroid</a>, <a href="https://www.tandfonline.com/doi/pdf/10.1080/23328940.2019.1632145">fever or menopause</a>.</p> <p>But hyperhidrosis can have no obvious cause, and the reasons behind this so-called primary hyperhidrosis are a bit of a mystery. People have normal numbers of sweat glands but researchers think they simply over-produce sweat after triggers such as stress, heat, exercise, tobacco, alcohol and hot spices. There may also be a genetic link.</p> <h2>OK, I sweat a lot. What can I do?</h2> <p><strong>1. Antiperspirants</strong></p> <p>Antiperspirants, particularly ones with <a href="https://onlinelibrary.wiley.com/doi/pdf/10.1111/ics.12852">aluminium</a>, are your first line of defence and are formulated to reduce sweating. Deodorants only stop body odour.</p> <p><a href="https://www.drugs.com/mtm/aluminum-chloride-hexahydrate-topical.html#:%7E:text=Aluminum%20chloride%20hexahydrate%20is%20an,excessive%20sweating%2C%20also%20called%20hyperhidrosis.">Aluminum chloride hexahydrate</a>, <a href="https://go.drugbank.com/drugs/DB11081">aluminium chloride</a> or the weaker <a href="https://cosmileeurope.eu/inci/detail/807/aluminum-zirconium-tetrachlorohydrex-gly/">aluminum zirconium tetrachlorohydrex glycinate</a> react with proteins in the sweat glands, forming a plug. This plug temporarily blocks the sweat ducts, reducing the amount of sweat reaching the skin’s surface.</p> <p>These products can contain <a href="https://www.termedia.pl/Journal/-7/pdf-46948-10?filename=Hyperhidrosis.pdf">up to 25%</a> aluminium. The higher the percentage the better these products work, but the more they irritate the skin.</p> <p><strong>2. Beat the heat</strong></p> <p>This might seem obvious, but staying cool can make a big difference. That’s because you have less heat to lose, so the body makes less sweat.</p> <p>Avoid super-hot, long showers (you will have more heat to loose), wear loose-fitting clothes made from breathable fabrics such as cotton (this allows any sweat you do produce to evaporate more readily), and carry a little hand fan to help your sweat evaporate.</p> <p>When exercising try <a href="https://pathprojects.com/blogs/news/how-to-make-an-ice-bandana-for-trail-running-and-hiking?srsltid=AfmBOorsJpNUDs_ZkAkJDFbDFFSeT5TtWsU4aqI4-_hHWbl_wuZLsgHn">ice bandanas</a> (ice wrapped in a scarf or cloth, then applied to the body) or wet towels. You can wear these around the neck, head, or wrists to reduce your body temperature.</p> <p>Try also to modify the time or place you exercise; try to find cool shade or air-conditioned areas when possible.</p> <p>If you have tried these first two steps and your sweating is still affecting your life, talk to your doctor. They can help you figure out the best way to manage it.</p> <p><strong>3. Medication</strong></p> <p>Some <a href="https://www.termedia.pl/Journal/-7/pdf-46948-10?filename=Hyperhidrosis.pdf">medications</a> can help regulate your sweating. Unfortunately some can also give you side effects such as a dry mouth, blurred vision, stomach pain or constipation. So talk to your doctor about what’s best for you.</p> <p>Your GP may also refer you to a dermatologist – a doctor like myself who specialises in skin conditions – who might recommend different treatments, including some of the following.</p> <p><strong>4. Botulinum toxin injections</strong></p> <p>Botulinum toxin injections are not just used for cosmetic reasons. They have many applications in medicine, including blocking the nerves that control the sweat glands. They do this for many months.</p> <p>A dermatologist usually gives the injections. But they’re only subsidised by <a href="https://www9.health.gov.au/mbs/fullDisplay.cfm?type=item&amp;q=18362&amp;qt=ItemID">Medicare</a> in Australia for the armpits and if you have primary hyperhidrosis that hasn’t been controlled by the strongest antiperspirants. These injections are given up to three times a year. It is not subsidised for other conditions, such as an overactive thyroid or for other areas such as the face or hands.</p> <p>If you don’t qualify, you can have these injections privately, but it will cost you hundreds of dollars per treatment, which can last up to six months.</p> <p><strong>5. Iontophoresis</strong></p> <p>This involves using a device that passes a weak electrical current through water to the skin to <a href="https://www.sciencedirect.com/science/article/am/pii/S254243272030014X">reducing sweating</a> in the hands, feet or armpits. Scientists aren’t sure exactly how it works.</p> <p>But this is the <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC9826940/">only way</a> to control sweating of the hands and feet that does not require drugs, surgery or botulinum toxin injections.</p> <p>This treatment is not subsidised by Medicare and not all dermatologists provide it. However, you can buy and use your own device, which tends to be cheaper than accessing it privately. You can ask your dermatologist if this is the right option for you.</p> <p><strong>6. Surgery</strong></p> <p>There is a procedure to cut certain nerves to the hands that stop them sweating. This is <a href="https://www.mdpi.com/2077-0383/11/3/786/pdf">highly effective</a> but can cause sweating to occur elsewhere.</p> <p>There are also other surgical options, which you can discuss with your doctor.</p> <p><strong>7. Microwave therapy</strong></p> <p>This is a <a href="https://www.tandfonline.com/doi/pdf/10.1080/09546634.2022.2089333">newer treatment</a> that zaps your sweat glands to destroy them so they can’t work any more. It’s not super common yet, and it is quite painful. It’s available privately in a few centres.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/239397/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/michael-freeman-223922"><em>Michael Freeman</em></a><em>, Associate Professor of Dermatology, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a></em></p> <p><em>Image credits: Shutterstock</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Balance declines with age, but exercise can help stave off some of the risk of falling

<p><em><a href="https://theconversation.com/profiles/evan-papa-1433146">Evan Papa</a>, <a href="https://theconversation.com/institutions/tufts-university-1024">Tufts University</a></em></p> <p>My wife and I were in the grocery store recently when we noticed an older woman reaching above her head for some produce. As she stretched out her hand, she lost her balance and began falling forward. Fortunately, she leaned into her grocery cart, which prevented her from falling to the ground.</p> <p>Each year, about <a href="https://www.cdc.gov/mmwr/volumes/65/wr/mm6537a2.htm">1 in every 4 older adults experience a fall</a>. In fact, falls are the leading cause of injuries in adults ages 65 and older. Falls are the <a href="https://doi.org/10.1007/bf00298717">most common cause of hip fractures</a> and <a href="https://doi.org/10.1111/j.1553-2712.2000.tb00515.x">traumatic brain injuries</a>.</p> <p>Injuries like those are also <a href="https://doi.org/10.1056/NEJM199710303371806">risk factors for placement in a nursing home</a>, where the fall risk is <a href="https://doi.org/10.7326/0003-4819-121-6-199409150-00009">nearly three times higher than for people living in the community</a>.</p> <p>A number of physical changes with aging often go unseen preceding falls, including muscle weakness, decreased balance and changes in vision.</p> <p>I am a <a href="https://facultyprofiles.tufts.edu/evan-papa">physical therapist</a> and <a href="https://scholar.google.com/citations?user=T9B_dHQAAAAJ&amp;hl=en">clinical scientist focused on fall prevention</a> in older adults, commonly ages 65 and older. I’ve spent most of my career investigating why older adults fall and working with patients and their families to prevent falls.</p> <h2>Why aging leads to increased risk of falls</h2> <p>Aging is a process that affects the systems and tissues of every person. The rate and magnitude of aging may be different for each person, but overall physical decline is an inevitable part of life. Most people think aging starts in their 60s, but in fact we spend most of our life span <a href="https://doi.org/10.1093%2Fgeront%2Fgnv130">undergoing the process of decline</a>, typically beginning in our 30s.</p> <p>Older adults are more prone to falling for various reasons, including age-related changes in their bodies and vision changes that leave them vulnerable to environmental factors such as curbs, stairs and carpet folds.</p> <figure><iframe src="https://www.youtube.com/embed/ztPbKP68P2Q?wmode=transparent&amp;start=24" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">Some straightforward measures to improve the safety of the home environment for older adults can significantly lower the risk of falls.</span></figcaption></figure> <p>Based on my experience, here are some common reasons older adults may experience falls:</p> <p>First, <a href="https://my.clevelandclinic.org/health/diseases/23167-sarcopenia">aging leads to a natural loss of muscle strength</a> and flexibility, making it more challenging to maintain balance and stability. The loss of strength and poor balance are two of the most common causes of falls.</p> <p>Second, older adults often have chronic conditions such as arthritis, Parkinson’s disease or diabetes that can affect their mobility, coordination and overall stability.</p> <p>In addition, certain medications commonly taken by older adults, <a href="https://doi.org/10.4088/jcp.18f12340">such as sedatives</a> or <a href="https://doi.org/10.1001/jamainternmed.2013.14764">blood pressure drugs</a>, can cause dizziness, drowsiness or a drop in blood pressure, leading to an increased risk of falls.</p> <p>Age-related vision changes, such as reduced depth perception and peripheral vision and difficulty in differentiating colors or contrasts, can make it harder to navigate and identify potential hazards. Hazards in the environment, such as uneven surfaces, slippery floors, inadequate lighting, loose rugs or carpets or cluttered pathways, can <a href="https://doi.org/10.1186/s12877-021-02499-x">significantly contribute to falls among older adults</a>.</p> <p>Older adults who lead a sedentary lifestyle or have limited physical activity may also experience reduced strength, flexibility and balance.</p> <p>And finally, such conditions as dementia or Alzheimer’s disease can affect judgment, attention and spatial awareness, leading to increased fall risk.</p> <h2>Theories of aging</h2> <p>There are numerous theories about why we age but there is no one unifying notion that explains all the changes in our bodies. A large portion of aging-related decline is <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3295054/">caused by our genes</a>, which determine the structure and function of bones, muscle growth and repair and visual depth perception, among other things. But there are also numerous lifestyle-related factors that influence our rate of aging including diet, exercise, stress and exposure to environmental toxins.</p> <p>A recent advance in scientific understanding of aging is that there is a difference between your <a href="https://theconversation.com/are-you-a-rapid-ager-biological-age-is-a-better-health-indicator-than-the-number-of-years-youve-lived-but-its-tricky-to-measure-198849">chronological age and your biological age</a>. Chronological age is simply the number of years you’ve been on the Earth. Biological age, however, refers to how old your cells and tissues are. It is based on physiological evidence from a blood test and is related to your physical and functional ability. Thus, if you’re healthy and fit, your biological age may be lower than your chronological age. However, the reverse can also be true.</p> <p>I encourage patients to focus on their biological age because it empowers them to take control over the aging process. We obviously have no control over when we are born. By focusing on the age of our cells, we can avoid long-held beliefs that our bodies are destined to develop cancer, diabetes or other conditions that <a href="https://doi.org/10.1016/j.cub.2012.07.024">have historically been tied to how long we live</a>.</p> <p>And by taking control of diet, exercise, sleep and other lifestyle factors you can actually <a href="https://doi.org/10.1111%2Facel.13538">decrease your biological age</a> and improve your quality of life. As one example, our team’s research has shown that moderate amounts of aerobic exercise <a href="https://doi.org/10.1371/journal.pone.0188538">can slow down motor decline</a> even when a person begins exercise in the latter half of the life span.</p> <h2>Fall prevention</h2> <p>Adopting lifestyle changes such as regular, long-term exercise can <a href="https://doi.org/10.1001/jamainternmed.2018.5406">reduce the consequences of aging</a>, including falls and injuries. Following a healthy diet, managing chronic conditions, reviewing medications with health care professionals, maintaining a safe home environment and getting regular vision checkups can also help reduce the risk of falls in older adults.</p> <p>There are several exercises that physical therapists use to improve balance for patients. It is important to note however, that before starting any exercise program, everyone should consult with a health care professional or a qualified physical therapist to determine the most appropriate exercises for their specific needs. Here are five forms of exercise I commonly recommend to my patients to improve balance:</p> <ol> <li> <p>Balance training can help improve coordination and <a href="https://www.sciencedirect.com/topics/neuroscience/proprioception">proprioception</a>, which is the body’s ability to sense where it is in space. By practicing movements that challenge the body’s balance, such as standing on one leg or walking heel-to-toe, the nervous system becomes better at coordinating movement and maintaining balance. A large research study analyzing nearly 8,000 older adults found that balance and functional exercises <a href="https://doi.org/10.1002/14651858.cd012424.pub2">reduce the rate of falls by 24%</a>.</p> </li> <li> <p>Strength training exercises involve lifting weights or using resistance bands to increase muscle strength and power. By strengthening the muscles in the legs, hips and core, older adults can improve their ability to maintain balance and stability. Our research has shown that strength training can also lead to <a href="https://doi.org/10.2147/cia.s104674">improvements in walking speed and a reduction in fall risk</a>.</p> </li> <li> <p>Tai chi is a gentle martial art that focuses on slow, controlled movements and shifting body weight. Research shows that it can improve balance, strength and flexibility in older adults. Several combined studies in tai chi have demonstrated a 20% reduction in the <a href="https://doi.org/10.1002/14651858.cd012424.pub2">number of people who experience falls</a>.</p> </li> <li> <p>Certain yoga poses can enhance balance and stability. Tree pose, warrior pose and mountain pose are examples of poses that can help improve balance. It’s best to <a href="https://theconversation.com/yoga-modern-research-shows-a-variety-of-benefits-to-both-body-and-mind-from-the-ancient-practice-197662">practice yoga</a> under the guidance of a qualified instructor who can adapt the poses to individual abilities.</p> </li> <li> <p>Flexibility training involves stretching the muscles and joints, which can improve range of motion and reduce stiffness. By improving range of motion, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3990889/">older adults can improve their ability to move safely</a> and avoid falls caused by limitations in mobility.</p> </li> <li> <p>Use of assistive devices can be helpful when strength or balance impairments are present. Research studies involving the evaluation of canes and walkers used by older adults confirm that <a href="https://doi.org/10.1016/j.apmr.2004.04.023">these devices can improve balance and mobility</a>. Training from a physical or occupational therapist in the proper use of assistive devices is an important part of improving safety.</p> </li> </ol> <p>When I think back about the woman who nearly fell in the grocery store, I wish I could share everything we have learned about healthy aging with her. There’s no way to know if she was already putting these tips into practice, but I’m comforted by the thought that she may have avoided the fall by being in the right place at the right time. After all, she was standing in the produce aisle.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/204174/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/evan-papa-1433146">Evan Papa</a>, Associate Professor of Physical Therapy and Rehabilitation Science, <a href="https://theconversation.com/institutions/tufts-university-1024">Tufts University</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

These 12 things can reduce your dementia risk – but many Australians don’t know them all

In fact, we all have the power to reduce our risk of developing dementia, no matter your age.</p> <p>Research shows your risk of developing dementia could be <a href="https://www.thelancet.com/article/S0140-6736(20)30367-6/fulltext">reduced by up to 40%</a> (and even higher if you live in a <a href="https://www.thelancet.com/journals/langlo/article/PIIS2214-109X(19)30074-9/fulltext">low or middle-income country</a>) by addressing lifestyle factors such as healthy diet, exercise and alcohol consumption.</p> <p>But the first step to reducing population-wide dementia risk is to understand how well people understand the risk factors and the barriers they may face to making lifestyle changes.</p> <p>Our new <a href="https://www.mdpi.com/2673-9259/2/4/21/htm">paper</a>, published this week in the <a href="https://www.mdpi.com/2673-9259/2/4/21/htm">Journal of Ageing and Longevity</a>, found most older people are aware that dementia is a modifiable condition and that they have the power to change their dementia risk.</p> <p>We also found the key barrier to making brain healthy lifestyle choices was a lack of knowledge, which suggests a public awareness campaign is urgently needed.</p> <h2>What we did</h2> <p>We began by <a href="https://www.mdpi.com/2673-9259/2/4/21/htm">reviewing</a> the published research to identify 12 factors shown to reduce dementia risk.

Some people do all the “right” things and still get dementia. But there is <a href="https://www.thelancet.com/article/S0140-6736(20)30367-6/fulltext">good evidence</a> managing lifestyle factors help make it <em>less likely</em> you will get dementia over your lifetime.</p> <p>Our study shows many older Australians are quite aware, with over 75% able to correctly identify more than four of the factors in our list of 12.</p> <p>However, few were able to name the less well-known risk factors, such as preventing heart disease and health conditions like kidney disease.</p> <p>The good news is that close to half of the sample correctly identified more than six of the 12 protective factors, with mentally active lifestyle, physical activity and healthy diet in the top three spots.</p> <h2>Two key issues</h2> <p>Two things stood out as strongly linked with the ability to identify factors influencing dementia risk.</p> <p>Education was key. People who received more than 12 years of formal schooling were more likely to agree that dementia was a modifiable condition. We are first exposed to health management in our school years and thus more likely to form healthier habits.</p> <p>Age was the other key factor. Younger respondents (less than 75 years old) were able to accurately identify more protective factors compared to older respondents. This is why health promotion initiatives and public education efforts about dementia are vital (such as Dementia Awareness Month and <a href="https://www.memorywalk.com.au/">Memory, Walk and Jog initiatives</a>).</p> <h2>How can these findings be used in practice?</h2> <p>Our findings suggest we need to target education across the different age groups, from children to older Australians.</p> <p>This could involve a <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/ajag.13049">whole system approach</a>, from programs targeted at <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5858574/#:%7E:text=Family%20Coaching%20has%20specific%20goals,to%20problem%20solve%20challenging%20situations.">families</a>, to educational sessions for school-aged children, to involving GPs in awareness promotion.</p> <p>We also need to tackle barriers that hinder dementia risk reduction. This means doing activities that motivate you, finding programs that suit your needs and schedule, and are accessible.</p> <h2>What does this mean for you?</h2> <p>Reducing your dementia risk means recognising change starts with you.</p> <p>We are all familiar with the everyday challenges that stop us from starting an exercise program or sticking to a meal plan.</p> <p>There are simple and easy changes we can begin with. Our team has developed a program that can help. We are offering limited <a href="https://www.brainbootcamp.com.au/">free brain health boxes</a>, which include information resources and physical items such as a pedometer.

Your friend has been diagnosed with cancer. Here are 6 things you can do to support them

<p><em><a href="https://theconversation.com/profiles/stephanie-cowdery-2217734">Stephanie Cowdery</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a>; <a href="https://theconversation.com/profiles/anna-ugalde-2232654">Anna Ugalde</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a>; <a href="https://theconversation.com/profiles/trish-livingston-163686">Trish Livingston</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a>, and <a href="https://theconversation.com/profiles/victoria-white-1888110">Victoria White</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a></em></p> <p>Across the world, <a href="https://www.who.int/news/item/01-02-2024-global-cancer-burden-growing--amidst-mounting-need-for-services">one in five</a> people are diagnosed with cancer during their lifetime. By age 85, almost <a href="https://www.cancer.org.au/cancer-information/what-is-cancer/facts-and-figures">one in two</a> Australians will be diagnosed with cancer.</p> <p>When it happens to someone you care about, it can be hard to know what to say or how to help them. But providing the right support to a friend can make all the difference as they face the emotional and physical challenges of a new diagnosis and treatment.</p> <p>Here are six ways to offer meaningful support to a friend who has been diagnosed with cancer.</p> <h2>1. Recognise and respond to emotions</h2> <p>When facing a cancer diagnosis and treatment, it’s normal to experience a range of <a href="https://www.canceraustralia.gov.au/impacted-by-cancer/emotions#:%7E:text=It's%20likely%20that%20feelings%20will,these%20feelings%20ease%20with%20time">emotions</a> including fear, anger, grief and sadness. Your friend’s moods may fluctuate. It is also common for feelings to <a href="https://link.springer.com/article/10.1007/s00520-014-2492-9">change over time</a>, for example your friend’s anxiety may decrease, but they may feel more depressed.</p> <p>Some friends may want to share details while others will prefer privacy. Always ask permission to raise sensitive topics (such as changes in physical appearance or their thoughts regarding fears and anxiety) and don’t make assumptions. It’s OK to tell them you feel awkward, as this acknowledges the challenging situation they are facing.</p> <p>When they feel comfortable to talk, follow their lead. Your support and willingness <a href="https://www.cancervic.org.au/get-support/stories/what-to-say-and-not-say.html">to listen without judgement</a> can provide great comfort. You don’t have to have the answers. Simply acknowledging what has been said, providing your full attention and being present for them will be a great help.</p> <h2>2. Understand their diagnosis and treatment</h2> <p><a href="https://onlinelibrary.wiley.com/doi/full/10.1002/pon.4722">Understanding</a> your friend’s diagnosis and what they’ll go through when being <a href="https://www.cancer.org/cancer/caregivers/what-a-caregiver-does/treatment-timeline.html">treated</a> may be helpful.</p> <p>Being informed can reduce your own worry. It may also help you to listen better and reduce the amount of explaining your friend has to do, especially when they’re tired or overwhelmed.</p> <p>Explore reputable sources such as the <a href="https://www.cancer.org.au/">Cancer Council website</a> for accurate information, so you can have meaningful conversations. But keep in mind your friend has a trusted medical team to offer personalised and accurate advice.</p> <h2>3. Check in regularly</h2> <p>Cancer treatment can be isolating, so regular check-ins, texts, calls or visits can help your friend feel less alone.</p> <p>Having a normal conversation and sharing a joke can be very welcome. But everyone copes with cancer differently. Be patient and flexible in your support – some days will be harder for them than others.</p> <p>Remembering key dates – such as the next round of chemotherapy – can help your friend feel supported. Celebrating milestones, including the end of treatment or anniversary dates, may boost morale and remind your friend of positive moments in their cancer journey.</p> <p>Always ask if it’s a good time to visit, as your friend’s immune system <a href="https://www.cancerresearchuk.org/about-cancer/what-is-cancer/body-systems-and-cancer/the-immune-system-and-cancer#:%7E:text=to%20fight%20cancer-,Cancer%20and%20treatments%20may%20weaken%20immunity,high%20dose%20of%20steroids">may be compromised</a> by their cancer or treatments such as chemotherapy or radiotherapy. If you’re feeling unwell, it’s best to postpone visits – but they may still appreciate a call or text.</p> <h2>4. Offer practical support</h2> <p>Sometimes the best way to show your care is through practical support. There may be different ways to offer help, and what your friend needs might change at the beginning, during and after treatment.</p> <p>For example, you could offer to pick up prescriptions, drive them to appointments so they have transport and company to debrief, or wait with them at appointments.</p> <p>Meals will always be welcome. However it’s important to remember cancer and its treatments may <a href="https://www.cancer.gov/about-cancer/treatment/side-effects/nutrition#effects-of-cancer-treatment-on-nutrition">affect</a> taste, smell and appetite, as well as your friend’s ability to eat enough or absorb nutrients. You may want to check first if there are particular foods they like. <a href="https://www.cancervic.org.au/downloads/resources/booklets/nutrition-cancer.pdf">Good nutrition</a> can help boost their strength while dealing with the side effects of treatment.</p> <p>There may also be family responsibilities you can help with, for example, babysitting kids, grocery shopping or taking care of pets.</p> <h2>5. Explore supports together</h2> <p>Studies <a href="https://pubmed.ncbi.nlm.nih.gov/35834503/">have shown</a> mindfulness practices can be an effective way for people to manage anxiety associated with a cancer diagnosis and its treatment.</p> <p>If this is something your friend is interested in, it may be enjoyable to explore classes (either online or in-person) together.</p> <p>You may also be able to help your friend connect with organisations that provide emotional and practical help, such as the Cancer Council’s <a href="https://www.cancer.org.au/support-and-services/cancer-council-13-11-20">support line</a>, which offers free, confidential information and support for anyone affected by cancer, including family, friends and carers.</p> <p><a href="https://www.researchgate.net/publication/5659099_Systematic_review_of_peer-support_programs_for_people_with_cancer">Peer support groups</a> can also reduce your friend’s feelings of isolation and foster shared understanding and empathy with people who’ve gone through a similar experience. GPs <a href="https://pubmed.ncbi.nlm.nih.gov/34333571/">can help</a> with referrals to support programs.</p> <h2>6. Stick with them</h2> <p>Be committed. Many people feel <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC11120751/">isolated</a> after their treatment. This may be because regular appointments have reduced or stopped – which can feel like losing a safety net – or because their relationships with others have changed.</p> <p>Your friend may also experience emotions such as worry, lack of confidence and uncertainty as they adjust to a <a href="https://www.cancer.gov/about-cancer/coping/survivorship/new-normal">new way of living</a> after their treatment has ended. This will be an important time to support your friend.</p> <p>But don’t forget: looking after <a href="https://www.healthdirect.gov.au/caring-for-someone-with-cancer">yourself</a> is important too. Making sure you eat well, sleep, exercise and have emotional support will help steady you through what may be a challenging time for you, as well as the friend you love.</p> <p><a href="https://www.deakin.edu.au/faculty-of-health/research/cancer-carer-hub">Our research</a> team is developing new programs and resources to support carers of people who live with cancer. While it can be a challenging experience, it can also be immensely rewarding, and your small acts of kindness can make a big difference.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/239844/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/stephanie-cowdery-2217734">Stephanie Cowdery</a>, Research Fellow, Carer Hub: A Centre of Excellence in Cancer Carer Research, Translation and Impact, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a>; <a href="https://theconversation.com/profiles/anna-ugalde-2232654">Anna Ugalde</a>, Associate Professor &amp; Victorian Cancer Agency Fellow, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a>; <a href="https://theconversation.com/profiles/trish-livingston-163686">Trish Livingston</a>, Distinguished Professor &amp; Director of Special Projects, Faculty of Health, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a>, and <a href="https://theconversation.com/profiles/victoria-white-1888110">Victoria White</a>, Professor of Pyscho-Oncology, School of Psychology, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Can you die from long COVID? The answer is not so simple

When symptoms persist for more than three months after the initial COVID infection, this is generally referred to as <a href="https://www.who.int/europe/news-room/fact-sheets/item/post-covid-19-condition">long COVID</a>.</p> <p>In September, Grammy-winning Brazilian musician <a href="https://www.abc.net.au/news/2024-09-07/brazilian-musician-sergio-mendez-dies-at-83/104323360">Sérgio Mendes</a> died aged 83 after reportedly having long COVID.</p> <p><a href="https://www.abs.gov.au/articles/covid-19-mortality-australia-deaths-registered-until-31-july-2023">Australian data</a> show 196 deaths were due to the long-term effects of COVID from the beginning of the pandemic up to the end of July 2023.</p> <p>In the United States, the Centers for Disease Control and Prevention reported 3,544 <a href="https://www.cdc.gov/nchs/pressroom/nchs_press_releases/2022/20221214.htm">long-COVID-related deaths</a> from the start of the pandemic up to the end of June 2022.</p> <p>The symptoms of <a href="https://www.healthdirect.gov.au/long-covid">long COVID</a> – such as fatigue, shortness of breath and “brain fog” – can be debilitating. But can you die from long COVID? The answer is not so simple.</p> <h2>How could long COVID lead to death?</h2> <p>There’s still a lot we don’t understand about what causes long COVID. A popular theory is that “zombie” <a href="https://www.pnas.org/doi/full/10.1073/pnas.2300644120">virus fragments</a> may linger in the body and cause inflammation even after the virus has gone, resulting in long-term health problems. Recent research suggests a reservoir of <a href="https://www.sciencedirect.com/science/article/abs/pii/S1198743X24004324?via%3Dihub">SARS-CoV-2 proteins</a> in the blood might explain why some people experience ongoing symptoms.</p> <p>We know a serious COVID infection can damage <a href="https://covid19.nih.gov/news-and-stories/long-term-effects-sars-cov-2-organs-and-energy#:%7E:text=What%20you%20need%20to%20know,main%20source%20of%20this%20damage">multiple organs</a>. For example, severe COVID can lead to <a href="https://www.hopkinsmedicine.org/health/conditions-and-diseases/coronavirus/covid-long-haulers-long-term-effects-of-covid19">permanent lung dysfunction</a>, persistent heart inflammation, neurological damage and long-term kidney disease.</p> <p>These issues can in some cases lead to death, either immediately or months or years down the track. But is death beyond the acute phase of infection from one of these causes the direct result of COVID, long COVID, or something else? Whether long COVID can <em>directly</em> cause death continues to be a topic of debate.</p> <p>Of the <a href="https://www.cdc.gov/nchs/data/vsrr/vsrr025.pdf">3,544 deaths</a> related to long COVID in the US up to June 2022, the most commonly recorded underlying cause was COVID itself (67.5%). This could mean they died as a result of one of the long-term effects of a COVID infection, such as those mentioned above.</p> <p>COVID infection was followed by heart disease (8.6%), cancer (2.9%), Alzheimer’s disease (2.7%), lung disease (2.5%), diabetes (2%) and stroke (1.8%). Adults aged 75–84 had the highest rate of death related to long COVID (28.8%).</p> <p>These findings suggest many of these people died “with” long COVID, rather than from the condition. In other words, long COVID may not be a direct driver of death, but rather a contributor, likely exacerbating existing conditions.</p> <h2>‘Cause of death’ is difficult to define</h2> <p>Long COVID is a relatively recent phenomenon, so mortality data for people with this condition are limited.</p> <p>However, we can draw some insights from the experiences of people with post-viral conditions that have been studied for longer, such as myalgic encephalomyelitis or chronic fatigue syndrome (ME/CFS).</p> <p>Like long COVID, <a href="https://bmjopen.bmj.com/content/12/5/e058128">ME/CFS</a> is a complex condition which can have significant and varied effects on a person’s physical fitness, nutritional status, social engagement, mental health and quality of life.</p> <p>Some research indicates people with ME/CFS are at <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5218818/">increased risk</a> of dying from causes including heart conditions, infections and suicide, that may be triggered or compounded by the debilitating nature of the syndrome.</p> <p>So what is the emerging data on long COVID telling us about the potential increased risk of death?</p> <p>Research from 2023 has suggested adults in the US with long COVID were at <a href="https://jamanetwork.com/journals/jama-health-forum/fullarticle/2802095">greater risk</a> of developing heart disease, stroke, lung disease and asthma.</p> <p>Research has also found <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC9721155/">long COVID</a> is associated with a higher risk of <a href="https://www.tandfonline.com/doi/full/10.1080/21642850.2022.2164498#abstract">suicidal ideation</a> (thinking about or planning suicide). This may reflect common symptoms and consequences of long COVID such as sleep problems, fatigue, chronic pain and emotional distress.</p> <p>But long COVID is more likely to occur in people who have <a href="https://www.aihw.gov.au/reports/covid-19/long-covid-in-australia-a-review-of-the-literature/summary">existing health conditions</a>. This makes it challenging to accurately determine how much long COVID contributes to a person’s death.</p> <p>Research has long revealed <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7302107/">reliability issues</a> in cause-of-death reporting, particularly for people with chronic illness.</p> <h2>So what can we conclude?</h2> <p>Ultimately, long COVID is a <a href="https://www.health.gov.au/topics/chronic-conditions/about-chronic-conditions">chronic condition</a> that can significantly affect quality of life, mental wellbeing and overall health.</p> <p>While long COVID is not usually immediately or directly life-threatening, it’s possible it could exacerbate existing conditions, and play a role in a person’s death in this way.</p> <p>Importantly, many people with long COVID around the world lack access to appropriate support. We need to develop <a href="https://www.mja.com.au/journal/2024/221/9/persistent-symptoms-after-covid-19-australian-stratified-random-health-survey">models of care</a> for the optimal management of people with long COVID with a focus on multidisciplinary care.</p> <p><em>Dr Natalie Jovanovski, Vice Chancellor’s Senior Research Fellow in the School of Health and Biomedical Sciences at RMIT University, contributed to this article.</em><img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/239184/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/rose-shiqi-luo-1477061"><em>Rose (Shiqi) Luo</em></a><em>, Postdoctoral Research Fellow, School of Health and Biomedical Sciences, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a>; <a href="https://theconversation.com/profiles/catherine-itsiopoulos-14246">Catherine Itsiopoulos</a>, Professor and Dean, School of Health and Biomedical Sciences, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a>; <a href="https://theconversation.com/profiles/kate-anderson-1412897">Kate Anderson</a>, Vice Chancellor's Senior Research Fellow, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a>; <a href="https://theconversation.com/profiles/magdalena-plebanski-1063786">Magdalena Plebanski</a>, Professor of Immunology, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a>, and <a href="https://theconversation.com/profiles/zhen-zheng-1321031">Zhen Zheng</a>, Associate Professor, STEM | Health and Biomedical Sciences, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.
