“I lost all ability to fly the plane”: Pilot's shock claim after plane drops mid-flight

<p>At least 50 passengers have been injured with a dozen hospitalised after a Boeing 787 Dreamliner suddenly plunged about two hours into the flight from Sydney to Auckland on Monday. </p> <p>LATAM Airlines said that the plane experienced an unspecified "technical event during the flight which caused a strong movement." </p> <p>Passengers on board the flight have recalled the terrifying moment the plane took a nose-dive mid-flight. </p> <p>"The plane dipped so dramatically into a nose dive for a couple of seconds and around 30 people hit the ceiling hard," Daniel, who was travelling from London, told the <em>NZ Herald</em>. </p> <p>“None of us knew what had happened until after the flight, I was just trying to keep everyone calm. We never heard any announcement from the captain." </p> <p>He added that passengers were screaming and it was hard to tell whether blood or red wine was splattered through the cabin. </p> <p>Another passenger, Brian Jokat, told broadcaster <em>RNZ t</em>hat the incident took place in "split seconds". </p> <p>"There was no pre-turbulence, we were just sailing smoothly the whole way,” he said. </p> <p>“I had just dozed off and I luckily had my seatbelt on, and all of a sudden the plane just dropped. It wasn’t one of those things where you hit turbulence and you drop a few times … we just dropped.”</p> <p>He added that a passenger two seats away from him, who was not wearing his seatbelt, flew up into the ceiling and was suspended mid-air before he fell and broke his ribs. </p> <p>“I thought I was dreaming,” he said. “I opened my eyes and he was on the roof of the plane on his back, looking down on me. It was like <em>The Exorcist</em>.”</p> <p>Paramedics and more than 10 emergency vehicles were waiting for passengers when the plane landed in Auckland. </p> <p>Around 50 patients were treated, with 12 of them hospitalised and one in serious condition. </p> <p>At least three of those treated were cabin crew. </p> <p>Jokat told <em>RNZ </em>that after the plane landed, the pilot came to the back and explained what had happened. </p> <p>"He said to me, ‘I lost my instrumentation briefly and then it just came back all of a sudden,’” Jokat said.</p> <p>In another interview with <em>Stuff.co.nz</em>, Jokat recalled the pilot also saying: “My gauges just blanked out, I lost all of my ability to fly the plane.” </p> <p>The airline's final destination was Santiago, Chile, but it was landing at Auckland Airport in accordance with its normal flight path, according to <em>Reuters</em>. </p> <p>"LATAM regrets the inconvenience and injury this situation may have caused its passengers, and reiterates its commitment to safety as a priority within the framework of its operational standards," the airline said.  </p> <p><em>Images: Brian Jokat/ News.com.au</em></p>

Not all mourning happens after bereavement – for some, grief can start years before the death of a loved one

<p><em><a href="https://theconversation.com/profiles/lisa-graham-wisener-1247893">Lisa Graham-Wisener</a>, <a href="https://theconversation.com/institutions/queens-university-belfast-687">Queen's University Belfast</a> and <a href="https://theconversation.com/profiles/audrey-roulston-1512057">Audrey Roulston</a>, <a href="https://theconversation.com/institutions/queens-university-belfast-687">Queen's University Belfast</a></em></p> <p>For many people, grief starts not at the point of death, but from the moment a loved one is diagnosed with a life-limiting illness.</p> <p>Whether it’s the diagnosis of an advanced cancer or a non-malignant condition such as dementia, heart failure or Parkinson’s disease, the psychological and emotional process of grief can begin many months or even years before the person dies. This experience of mourning a future loss is known as <a href="https://link.springer.com/referenceworkentry/10.1007/978-3-319-69892-2_1006-1">anticipatory grief</a>.</p> <p>While not experienced by everyone, anticipatory grief is a <a href="https://spcare.bmj.com/content/bmjspcare/early/2022/02/10/bmjspcare-2021-003338.full.pdf?casa_token=IWNMDFN5SoIAAAAA:2EybwyPcKu73VdrACTNk7jITor-mMIXK8rv76arXgdjV9cA2Y0MV0LyZLLwcYe1rZUAQymOzFYo">common</a> part of the grieving process and can include a range of conflicting, often difficult thoughts and emotions. For example, as well as feelings of loss, some people can experience guilt from wanting their loved one to be free of pain, or imagining what life will be like after they die.</p> <h2>Difficult to define, distressing to experience</h2> <p>Anticipatory grief has proved <a href="https://journals.sagepub.com/doi/full/10.1177/02692163221074540#bibr13-02692163221074540">challenging to define</a>.

This lack of consensus has limited research progress, because there’s no shared understanding of how to identify anticipatory grief.</p> <p>Therese Rando, a <a href="https://www.taylorfrancis.com/chapters/edit/10.4324/9781315800806-9/grief-mourning-accommodating-loss-therese-rando">prominent theorist</a>, has proposed that anticipatory grief can help prepare for death, contributing to a more positive grieving experience post-bereavement. Rando also suggests that pre-death mourning can aid with adjustment to the loss of a loved one and reduce the risk of <a href="https://www.cruse.org.uk/understanding-grief/effects-of-grief/complicated-grief/">“complicated grief”</a>, a term that describes persistent and debilitating emotional distress.</p> <figure><iframe src="https://www.youtube.com/embed/AapGn60DZSA?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>But pre-death mourning doesn’t necessarily mean grief will be easier to work through once a loved one has died.

Witnessing close-up someone’s deterioration and decline in independence, memory or ability to perform routine daily tasks, such as personal care, is a painful experience.</p> <p>It is essential, then, for carers to acknowledge difficult emotions and seek support from those around them – especially because caring for a loved one at the end of their life <a href="https://www.mind.org.uk/information-support/helping-someone-else/carers-friends-family-coping-support/your-mental-health/">can be an isolating time</a>.</p> <p>Where possible, it can also be beneficial for carers to offer their loved one <a href="https://compassionatecommunitiesni.com/our-programs/dying-to-talk/">opportunities to reflect</a> on significant life events, attend to unfinished business, and to discuss preferences for funeral arrangements. For some, this may involve supporting loved ones to reconnect with friends and family, helping them to put legal or financial affairs in order, talking about how the illness is affecting them, or making an <a href="https://www.england.nhs.uk/publication/universal-principles-for-advance-care-planning/">advance care plan</a>.</p> <figure><iframe src="https://www.youtube.com/embed/wrJaTXW1Xvk?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <h2>Talking is key</h2> <p>Living with altered family dynamics, multiple losses, transition and uncertainty can be <a href="https://www.tandfonline.com/doi/full/10.1080/07481187.2021.1998935">distressing for all family members</a>. It may be difficult to manage the emotional strain of knowing death is unavoidable, to make sense of the situation, and to <a href="https://hospicefoundation.ie/i-need-help/i-am-seriously-ill/how-to-talk-to-those-you-care-about/">talk about dying</a>.</p> <p>However, talking is key in <a href="https://www.cruse.org.uk/about/blog/important-conversations-death/">preparing for an impending death</a>. Organisations who offer specialist palliative care have information and trained professionals to help with difficult conversations, including <a href="https://www.mariecurie.org.uk/help/support/diagnosed/talking-children/children">talking to children</a> about death and dying.</p> <p>Navigating anticipatory grief can involve self-compassion for both the patient and carer. This includes acknowledging difficult emotions and treating oneself with kindness. Open communication with the person nearing the end of their life can foster emotional connection and help address their concerns, alongside support from the wider circle of family and friends.</p> <p>Extending empathy and understanding to those nearing death – and those grieving their impending loss – will help contribute to a compassionate community that supports those experiencing death, dying and bereavement.<!-- Below is The Conversation's page counter tag.

All of the incredible royal jewels Queen Mary just inherited

<p>In a weekend filled with regal splendour and historic significance, Crown Princess Mary of Denmark not only <a href="https://www.oversixty.co.nz/lifestyle/family-pets/king-charles-message-to-mary-as-she-becomes-queen" target="_blank" rel="noopener">ascended to the esteemed title of Queen</a> but also found herself adorned with the resplendent Danish Crown Jewels.</p> <p>The symbolic transfer of these extraordinary treasures, formerly belonging to Queen Margrethe, marks a momentous chapter in the Danish monarchy, and for Mary, it's a journey into the rich history of royal glamour.</p> <p>The Danish Crown Jewels, a collection with a lineage spanning centuries, tell a story of devotion, legacy and timeless elegance. Initiated by Queen Sophie Magdalene in the 1700s, each subsequent queen has contributed to and enhanced the collection, resulting in four dazzling "parures", or sets, each a testament to the enduring craftsmanship and artistry of Danish royalty.</p> <p><strong>The Emerald Set: A Gift of Love Across Generations</strong></p> <p>At the heart of the collection is the Emerald Set, a masterpiece featuring diadem, necklace, brooch and earrings adorned with emeralds and brilliant-cut diamonds. Originally gifted to Queen Sophie Magdalene in 1723 by King Christian VI, the set exudes a captivating blend of history and sophistication. As Queen Margrethe has demonstrated in the past, the pieces can be worn together or detached for a versatile, regal allure.</p> <p><strong>Pearl Ruby Set: A Timeless Elegance in Red and White</strong></p> <p>The Pearl Ruby Set, with its origins in the late 1600s, boasts a pearl necklace from Queen Charlotte Amalie, complemented by a matching pearl, ruby and diamond brooch and earrings. The ensemble, enhanced by Queen Caroline Amalie in the 1840s, mirrors the colours of the Danish flag. The set's adaptability, such as the pendant attachment to the pearl necklace, reflects a harmonious blend of tradition and innovation.</p> <p><strong>Brilliant Set: Diamonds that Sparkle with History</strong></p> <p>The Brilliant Set, featuring a brilliant-cut diamond necklace, floral bouquet brooch and earrings dating back to 1840, was the choice of Queen Margrethe for her son Frederik's wedding. This set, rich in symbolism, is a dazzling testament to the enduring sparkle of Danish royalty. Paired with the Floral Aigrette tiara, it adds a touch of timeless grace to any royal occasion.</p> <p><strong>Rose Cut Set: A Delicate Affair with Rose-Cut Diamonds</strong></p> <p>The Rose Cut Set, with necklaces and brooches fashioned from rose-cut diamonds, whispers tales of Princess Charlotte Amalie from centuries past. Worn sparingly by Queen Margrethe, it holds a unique place in the collection, and its rare appearances evoke a sense of antiquity and refinement.</p> <p>For Queen Mary, this accession to the Danish Crown Jewels is not just a privilege but a responsibility to carry forward the legacy of elegance and grace. These jewels, worn by every Queen of Denmark since the 1700s, are not merely adornments; they are a connection to the nation's history and a symbol of continuity.</p> <p>Reserved for special occasions, such as state visits and the New Year Reception, the Danish Crown Jewels will now find a new muse in Queen Mary. Ensconced within the walls of Rosenborg Castle when not in use, these jewels remain a source of pride for Denmark, a tangible link to its regal past.</p> <p>As Queen Mary steps into this new chapter of her royal journey, the Danish Crown Jewels will undoubtedly witness many more moments of joy, solemnity and regal radiance, reflecting the enduring spirit of a nation intertwined with its royal heritage.</p> <p><em>Images: Instagram / Getty Images</em></p>

I’m trying to lose weight and eat healthily. Why do I feel so hungry all the time? What can I do about it?

<p><em><a href="https://theconversation.com/profiles/nick-fuller-219993">Nick Fuller</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>Benjamin Franklin, one of the founding fathers of the United States, famously said nothing is certain except death and taxes. But I think we can include “you’ll feel hungry when you’re trying to lose weight” as another certainty.</p> <p>The reason is basic biology. So how does this work – and what can you do about it?</p> <h2>Hormones control our feelings of hunger</h2> <p>Several hormones play an essential role in regulating our feelings of hunger and fullness. The most important are ghrelin – often called the hunger hormone – and leptin.</p> <p>When we’re hungry, <a href="https://pubmed.ncbi.nlm.nih.gov/11739476/">ghrelin</a> is released by our stomach, lighting up a part of our brain called the hypothalamus to tell us to eat.</p> <p>When it’s time to stop eating, hormones, including <a href="https://pubmed.ncbi.nlm.nih.gov/8717038/">leptin</a>, are released from different organs, such as our gut and fat tissue, to signal to the brain that we’re full.</p> <h2>Dieting disrupts the process</h2> <p>But when we change our diet and start losing weight, we disrupt how these <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4766925/">appetite hormones function</a>.</p> <p>This triggers a process that stems from our hunter-gatherer ancestors. Their bodies developed this mechanism as a survival response to adapt to periods of deprivation and protect against starvation.</p> <p>The levels of hormones <a href="https://pubmed.ncbi.nlm.nih.gov/23126426/">managing our hunger increase</a>, making us feel hungrier to tell us to eat more, while the ones responsible for signalling we’re full decrease their levels, intensifying our feelings of hunger.</p> <p>We end up increasing our calorie consumption so we eat more to regain the weight we lost.</p> <p>But worse, even after the kilos creep back on, <a href="https://pubmed.ncbi.nlm.nih.gov/22029981/">our appetite hormones don’t restore</a> to their normal levels – they keep telling us to eat more so we put on a little extra fat. This is our body’s way of preparing for the next bout of starvation we will impose through dieting.</p> <p>Fortunately, there are things we can do to manage our appetite, including:</p> <h2>1. Eating a large, healthy breakfast every day</h2> <p>One of the easiest ways to manage our feelings of hunger throughout the day is to eat most of our food earlier in the day and taper our meal sizes so dinner is the smallest meal.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/32073608/">Research</a> shows a low-calorie or small breakfast leads to increased feelings of hunger, specifically appetite for sweets, across the course of the day.</p> <p><a href="https://www.cell.com/cell-metabolism/fulltext/S1550-4131(22)00344-8">Another study</a> found the same effect. Participants went on a calorie-controlled diet for two months, where they ate 45% of their calories for breakfast, 35% at lunch and 20% at dinner for the first month, before switching to eat their largest meal in the evening and their smallest in the morning. Eating the largest meal at breakfast resulted in decreased hunger throughout the day.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/32073608/">Research</a> also shows we burn the calories from a meal 2.5-times more efficiently in the morning than the evening. So emphasising breakfast over dinner is good not just for hunger control, but also weight management.</p> <h2>2. Prioritising protein</h2> <p>Protein helps contain feelings of hunger. This is because protein-rich foods such as lean meats, tofu and beans suppress the appetite-stimulating ghrelin and stimulate another hormone called <a href="https://www.sciencedirect.com/science/article/pii/S1550413106002713">peptide YY</a> that makes you feel full.</p> <p>And just as eating a breakfast is vital to managing our hunger, what we eat is important too, with <a href="https://pubmed.ncbi.nlm.nih.gov/24703415/">research</a> confirming a breakfast containing protein-rich foods, such as eggs, will leave us feeling fuller for longer.</p> <p>But this doesn’t mean just eating foods with protein. Meals need to be balanced and include a source of protein, wholegrain carb and healthy fat to meet our dietary needs. For example, eggs on wholegrain toast with avocado.</p> <h2>3. Filling up with nuts and foods high in good fats and fibre</h2> <p>Nuts often get a bad rap – thanks to the misconception they cause weight gain – but nuts can help us manage our hunger and weight. The filling fibre and good fats found in nuts take longer to digest, meaning our hunger is satisfied for longer.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/12791613/">Studies</a> suggest you can include up to 68 grams per day of nuts without affecting your weight.</p> <p>Avocados are also high in fibre and heart-healthy monounsaturated fats, making them another excellent food for managing feelings of fullness. This is backed by a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6567160/">study</a> confirming participants who ate a breakfast incorporating avocado felt more satisfied and less hungry than participants who ate a meal containing the same calories but with lower fat and fibre content.</p> <p>Similarly, eating foods that are high in soluble fibre – such as <a href="https://pubmed.ncbi.nlm.nih.gov/24820437/">beans</a> and vegetables – make us feel fuller. This type of fibre attracts water from our gut, forming a gel that slows digestion.</p> <h2>4. Eating mindfully</h2> <p>When we take time to really be aware of and enjoy the food we’re eating, we slow down and eat far less.</p> <p>A <a href="https://pubmed.ncbi.nlm.nih.gov/28718396/">review</a> of 68 studies found eating mindfully helps us better recognise feelings of fullness. Mindful eating provides our brain enough time to recognise and adapt to the signals from our stomach telling us we’re full.</p> <p>Slow down your food consumption by sitting at the dinner table and use smaller utensils to reduce the volume of food you eat with each mouthful.</p> <h2>5. Getting enough sleep</h2> <p>Sleep deprivation disturbs our <a href="https://www.sciencedirect.com/science/article/abs/pii/S1389945708700133">appetite hormones</a>, increasing our feelings of hunger and <a href="https://www.nature.com/articles/ncomms3259">triggering cravings</a>. So aim to get at least seven hours of uninterrupted sleep a night.</p> <p>Try switching off your devices <a href="https://journals.sagepub.com/doi/full/10.1177/1477153515584979">two hours before bed</a> to boost your body’s secretion of sleep-inducing hormones like melatonin.</p> <h2>6. Managing stress</h2> <p>Stress increases our <a href="https://pubmed.ncbi.nlm.nih.gov/18568078/">body’s production of cortisol</a> and triggers food cravings.</p> <p>So take time out when you need it and set aside time for stress-relieving activities. This can be as simple as getting outdoors. A <a href="https://www.frontiersin.org/articles/10.3389/fpsyg.2019.00722/full">2019 study</a> found sitting or walking outdoors at least three times a week could reduce cortisol levels by 21%.</p> <h2>7. Avoiding depriving ourselves</h2> <p>When we change our diet to lose weight or eat healthier, we typically restrict certain foods or food groups.</p> <p>However, this <a href="https://pubmed.ncbi.nlm.nih.gov/18568078/">heightens activity</a> in our mesocorticolimbic circuit – the reward system part of the brain – often resulting in us craving the foods we’re trying to avoid. Foods that give us pleasure release feel-good chemicals called endorphins and learning chemicals called dopamine, which enable us to remember – and give in to – that feel-good response.</p> <p>When we change our diet, activity in our hypothalamus – the clever part of the brain that regulates emotions and food intake – <a href="https://pubmed.ncbi.nlm.nih.gov/18568078/">also reduces</a>, decreasing our control and judgement. It often triggers a psychological response dubbed the “what-the-hell effect”, when we indulge in something we think we shouldn’t feel guilty about and then go back for even more.</p> <p>Don’t completely cut out your favourite foods when you go on a diet or deprive yourself if you’re hungry. It will take the pleasure out of eating and eventually you’ll give into your cravings.</p> <p><em>At the Boden Group, Charles Perkins Centre, we are studying the science of obesity and running clinical trials for weight loss.

Worrying news – ozone layer not recovering after all

<p>Alarming news from New Zealand scientists suggests the ozone layer might not be recovering after all, with the problem exacerbated by bushfires, volcanic eruptions and greenhouse gas emissions.</p> <div class="copy"> <p>The research <a href="https://doi.org/10.1038/s41467-023-42637-0" target="_blank" rel="noopener">published</a> in <em>Nature Communications</em> suggests the Antarctic ozone layer has reduced by 26% since 2004, contrary to previous reports of recovery by actions taken under an agreement called the Montreal Protocol. </p> <p>The authors say wildfire and volcanic aerosols together with greenhouse gas emissions probably explain recent setbacks with record large, long-lived ozone holes re-emerging over Antarctica during Spring since 2020.</p> <p>Climate change is influencing the <a href="http://www.bom.gov.au/weather-services/fire-weather-centre/bushfire-weather/index.shtml" target="_blank" rel="noopener">severity and frequency</a> of bushfires.</p> <p>The ozone hole was previously thought to be under repair thanks to a global agreement signed in Montreal, Canada to limit ozone depleting substances. </p> <p>But the paper finds insignificant long-term change in the total ozone column since the early 2000s, “even where significant recovery has previously been reported”.</p> <p>The analysis of daily and monthly ozone changes between 2001 – 2022, show delays in the formation of the ozone hole. While early springtime shows signs of recovery in the ozone layer, this is followed by declines during late September.</p> <p>Researcher and author Hannah Kessenich from the University of Otago says: “by looking at detailed, daily ozone observations from the last 19 years, we find evidence of much less ozone in the centre of the Antarctic ozone hole compared to 19 years ago. This means that the hole has not only remained large in area, but it has also become deeper (i.e. has less ozone) throughout most of Antarctic spring.”</p> <p>But Atmospheric scientist, Dr Martin Jucker from the University of NSW is not convinced by the results of the study.</p> <p>He says: “Their results rely heavily on the large ozone holes we have seen in 2020-2022. However, existing literature has already found reasons for these large ozone holes: Smoke from the 2019 bushfires and a volcanic eruption (La Soufriere), as well as a general relationship between the polar stratosphere and El Niño Southern Oscillation […] The years 2020-22 have seen a rare triple La Niña, but this relationship is never mentioned in the study.”  </p> <p><a href="https://cosmosmagazine.com/earth/earth-sciences/ozone-hole-among-largest-on-record/">This Spring</a>, the European Space Agency reported yet another large ozone hole had formed, among the biggest on record.</p> <p>The layer of ozone high in the atmosphere protects the Earth from ultraviolet (UV) radiation from the Sun.

The BMI isn’t all its cracked up to be

<p>The obsession people have with weight is nothing new. But as the relationship between science and weight evolves, health professionals are increasingly advocating for a shift away from one of the most often used tools as an individual measure of health.</p> <div class="copy"> <p>The Body Mass Index – or BMI – has been used for the past half century as a standard measurement tool for weight and obesity. It’s calculated by dividing a person’s weight in kilograms by the square of their height in metres.</p> <p>This produces a figure which is indexed on a spectrum of weight ranges. A BMI below 18.5 is considered underweight, above 25 is overweight, and above 30 is obese.</p> <p>The latest episode of <em>Debunks</em>, a new podcast from Cosmos, investigates how useful the BMI actually is for assessing health.</p> <p>Health advocacy bodies, health insurers and government departments all make reference to the BMI as being a globally recognised standard for weight classification.</p> <p>Most – but not all – <a href="https://cosmosmagazine.com/health/bmi-overweight-obese-healthy-deaths/">acknowledge that the tool is imperfect</a>. Its <a href="https://cosmosmagazine.com/health/body-and-mind/body-mass-index-miscalculation/">simple arithmetic</a> is based on a system devised by 19th-century Belgian mathematician Adolphe Quetelet, who was an early pioneer of the social sciences and the use of data to understand human trends.</p> <p>The so-called ‘Quetelet Index’ was first described in 1832 as a means of trying to identify a calculation for the average man, first by conducting cross-sectional studies of infants and then adults.</p> <p>The need to consider weight as an indicator for health, mortality and morbidity, saw scientists trial several measurements before settling on Quetelet’s formula and rebranding it as the BMI in 1972.</p> <p>The problem? The BMI was largely based on studies of Anglo-Saxon populations. This is one of the biggest limitations often recognised by health groups. The Australian Department of Health, for instance, notes that a healthy BMI range is generally lower for people of Asian backgrounds, and higher for those of Polynesian backgrounds.</p> <p>But ethnicity isn’t the only limiting factor. Age and pregnancy status also play a part. Even athletes with more lean muscle (which weighs more than fat) might also find the standard BMI doesn’t capture their health status accurately.</p> <p>Diets and lifestyles have also shifted from the 19th century Belgian standard, and even from those of 50 years ago. Health professionals have long supported a shift away from the BMI being used as a rolled gold indicator of individual health, and medical professionals are beginning to take a wider view of patient health.</p> <p>“There has been a recent change in the position from the [US] National Academies of Nutrition and Dietetics surrounding BMI and there are shifts in the guidelines around BMI for medical diagnosis,” Dr Emma Beckett, a molecular nutritionist at the University of Newcastle, tells <em>Debunks</em>.</p> <p>The same goes for other measurements like waist-to-hip ratios and waist circumference. These metrics are often used by researchers conducting large population studies, but they don’t necessarily explain a person’s ‘health picture’.</p> <p>“Because we measure them in so many of our research studies, people mistakenly believe they are the most important markers of health and it’s just not true. Health is so much more complicated,” Beckett says.</p> <p>“The ‘normal’ [BMI] category is the one with the lowest health risks, but it doesn’t mean being in that category means you have no health risks and it doesn’t mean if you just get yourself into that category and change nothing else, there are no health risks.”</p> <p>On the latest series of Debunks, a podcast from Cosmos and 9Podcasts, find out how weight – and measurements like the BMI – are much more complicated than they might seem.</p> <p><iframe title="Weight: Should you care about your BMI?" src="https://omny.fm/shows/debunks/weight-should-you-care-about-your-bmi/embed" width="100%" height="180" frameborder="0"></iframe></p> <div><em>Image credits: Shutterstock</em></div> <div style="background-color: #f4f4f4; padding-top: 20px; padding-right: 20px; padding-bottom: 20px;"><em><a href="https://cosmosmagazine.com/health/body-and-mind/the-bmi-isnt-all-its-cracked-up-to-be/">This article</a> was originally published on <a href="https://cosmosmagazine.com">Cosmos Magazine</a> and was written by <a href="null">Cosmos</a>. </em></div> </div>

All the reasons you might be having night sweats – and when to see a doctor

<p><em><a href="https://theconversation.com/profiles/siobhan-banks-18473">Siobhan Banks</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a> and <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></em></p> <p>You’ve finished a workout, so you’re hot and drenched with perspiration – but soon you begin to feel cool again. Later, it’s a sweltering summer evening and you’re finding it hard to sleep, so you kick off the covers.</p> <p>Sweating is a normal part of the body’s cooling system, helping to release heat and maintain optimal body temperature. But regularly waking up during the night, soaked through from excessive sweating is not.</p> <p>Night sweats are <a href="https://www.mayoclinic.org/symptoms/night-sweats/basics/definition/sym-20050768">repeated episodes</a> of excessive or intense sweating at night. They are an unpleasant part of life for many people.</p> <p>Many conditions and factors can trigger night sweats by changing the body’s tightly regulated temperature set point, at which the body attempts to maintain its <a href="https://www.tandfonline.com/doi/full/10.4161/temp.29702">core temperature</a>. Some triggers are harmless (a hot bedroom) or even related to positive lifestyle changes (exercise). Others have an underlying cause like menopause, infection, disease or medication.</p> <h2>Temperature control and sweating</h2> <p>The hypothalamus, located in the brain, is part of the <a href="https://www.hormones-australia.org.au/the-endocrine-system/">endocrine system</a> and the temperature control centre for the body. It contains <a href="https://www.statpearls.com/point-of-care/29920#ref_19631766">temperature sensors</a> that receive information from nerve cells (thermoreceptors) located centrally (in the organs) and peripherally in the skin.</p> <p>Thermoreceptors detect changes in body temperature, sending signals back to the hypothalamus. These <a href="https://www.sciencedirect.com/science/article/pii/S1876034111000256">signals</a> will either activate sweating to cool the body or shivering to warm the body.</p> <h2>Hormones and night sweats</h2> <p>Anyone, regardless of age or gender, can experience night sweats. But women experience night sweats more often than men, largely because menopause and associated changing hormone levels are <a href="https://www.tandfonline.com/doi/abs/10.3109/13697137.2011.608596">a leading cause</a>.</p> <p>Approximately 80% of women experience <a href="https://link.springer.com/article/10.1007/s00737-007-0209-5">hot flashes</a> (also called hot flushes) or night sweats after <a href="https://www.menopause.org.au/hp/information-sheets/what-is-menopause">menopause</a> (when periods have ceased for 12 months) and during <a href="https://www.healthdirect.gov.au/perimenopause">perimenopause</a> (the time leading up to it).</p> <p>While both hot flashes and night sweats produce a feeling of overheating, they are different experiences associated with menopause. Hot flashes occur during the day, are transient episodes of flushing and may involve sweating. Night sweats occur at night and involve an intense period of <a href="https://www.proquest.com/docview/2821423865?accountid=14649">sweating</a>. Changing oestrogen levels are thought to impact norepinephrine and serotonin levels, two neurotransmitters that influence <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6459071/#:%7E:text=%5B21%5D%20Estrogens%20stimulate%20the%20production,norepinephrine%20which%20disturbs%20hypothalamic%20thermostat">temperature regulation</a> in the hypothalamus.</p> <p>Hormones also influence night sweats in men, particularly those with low <a href="https://www.healthdirect.gov.au/testosterone">testosterone</a> levels, known as <a href="https://www.hormones-australia.org.au/endocrine-diseases/hypogonadism/">hypogonadism</a>. Around 38% of men aged 45 years or older have low testosterone <a href="https://www.scielo.br/j/ibju/a/RZqqfTn5tY6BFpV6rp3GMxJ/">levels</a> but it can affect men at any age.</p> <h2>Infections, disease and medications</h2> <p>When fighting infection, our body temperature often <a href="https://europepmc.org/article/nbk/nbk562334">rises</a>. This can stimulate sweating to cool and decrease body <a href="https://www.sciencedirect.com/science/article/pii/S1876034111000256">temperature</a>.</p> <p>Minor infections like the common cold can cause night sweats. They are also a symptom of serious infections such as human immunodeficiency virus (HIV) and diseases such as <a href="https://www.aafp.org/pubs/afp/issues/2020/0101/p34.html">Hodgkin’s</a> and <a href="https://link.springer.com/article/10.2165/00002018-200831020-00002">non-Hodgkin’s lymphoma</a>. However, night sweats are rarely the only symptom present.</p> <p>Medications such as selective serotonin reuptake inhibitors (SSRIs), corticosteroids, thyroid hormone replacement and methadone can cause night sweats. These medications affect parts of the <a href="https://link.springer.com/article/10.2165/00002018-200831020-00002">brain</a> and neurotransmitters that control and stimulate sweating.</p> <p>Regular alcohol (particularly alcohol dependence) and recreational drug use can also <a href="https://link.springer.com/article/10.2165/00002018-200831020-00002">increase the risk</a> of night sweats.</p> <h2>Stress, snoring and strenuous exercise</h2> <p>Night sweats are commonly reported by people with <a href="https://karger.com/spp/article-abstract/26/2/92/295722/Psychological-Sweating-A-Systematic-Review-Focused?redirectedFrom=fulltext">anxiety</a>.</p> <p>Psychological stress activates the body’s fight or flight system releasing neurotransmitters that increase heart rate, respiration, and blood pressure. This causes the body to heat up, at which point it starts sweating to cool the body back down. Night sweats may also increase anxiety, causing more sweating which in turn leads to less sleep and more anxiety.</p> <p>If anxiety causes night sweats and this causes distress, it’s best to get up, move around and engage in a <a href="https://www.calmclinic.com/anxiety/symptoms/night-sweats">calming routine</a>, preferably in a dark or dimly lit room.</p> <p>Night sweats have similarly been connected with sleep disorders like <a href="https://www.healthdirect.gov.au/obstructive-sleep-apnoea">obstructive sleep apnoea</a>, where the airway is repeatedly blocked during sleep and there is loud snoring. About one third of people with obstructive sleep apnoea regularly <a href="https://link.springer.com/article/10.1007/s11325-011-0502-4">experience night sweats</a>. The exact cause is undetermined but research shows it is linked with low blood oxygen levels (<a href="https://link.springer.com/article/10.1007/s11325-022-02701-3">hypoxemia</a>) and/or <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/j.1365-2869.2009.00743.x">high blood pressure</a>.</p> <p>People can experience night sweats after high-intensity workouts. Vigorous exercise can stimulate the thyroid, <a href="https://www.ncbi.nlm.nih.gov/books/NBK500006/#:%7E:text=Thyroid%20hormone%20increases%20the%20basal,respiration%20rate%2C%20and%20body%20temperature">increasing basal metabolic rate</a> and body temperature for up to <a href="https://journals.lww.com/acsm-msse/Fulltext/2011/09000/A_45_Minute_Vigorous_Exercise_Bout_Increases.6.aspx">14 hours post exercise</a>. So night sweats can occur even after a vigorous morning workout.</p> <p>Night sweats can indicate overtraining and/or under-fuelling. If not enough calories are consumed to support the increase in training, blood sugar could drop and you could experience <a href="https://www.aafp.org/pubs/afp/issues/2003/0301/p1019.pdf">hypoglycaemia</a>, which can cause night sweats.</p> <h2>When to seek help and 5 things to try</h2> <p>There are <a href="https://www.aafp.org/pubs/afp/issues/2020/1001/p427.html">numerous</a> health conditions and medications that can cause night sweats and interfere with sleep.</p> <p>If night sweats are regular, distressing, interfere with sleep or are accompanied by symptoms such as fatigue or weight loss (not related to lifestyle or diet changes) talk to a doctor to help determine the cause. They might suggest alternative medications to any you’re taking or recommend tests or investigations.</p> <p>In the meantime, you can try the following ideas:</p> <p><strong>1.</strong> sleep in a cool room and use a fan if needed</p> <p><strong>2.</strong> don’t overdress for bed. Wear breathable cotton or linen pyjamas</p> <p><strong>3.</strong> choose lightweight bedding you can kick off.

Lots of women try herbs like black cohosh for menopausal symptoms like hot flushes – but does it work?

<p><em><a href="https://theconversation.com/profiles/sasha-taylor-1461085">Sasha Taylor</a>, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> and <a href="https://theconversation.com/profiles/susan-davis-10376">Susan Davis</a>, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a></em></p> <p>Menopause is the stage of life where the ovaries stop releasing eggs and menstrual periods cease. Most Australian women go through menopause between <a href="https://www.nature.com/articles/nrdp20154">45 and 55</a> years of age, with the average age being 51 years, although some women may be younger.</p> <p>Hot flushes and night sweats are <a href="https://www.nature.com/articles/nrendo.2017.180">typical symptoms</a> of menopause, with vaginal dryness, muscle and joint pains, mood changes and sleep disturbance also commonly reported. Up to <a href="https://pubmed.ncbi.nlm.nih.gov/25706184/">75% of women</a> experience menopausal symptoms, with nearly 30% severely affected.</p> <p>These symptoms can negatively impact day-to-day life and wellbeing. The main therapies available include menopausal hormone therapy (MHT) and non-hormonal prescription therapy. Some women will elect to try complementary and alternative medicines, such as herbal medicines and nutritional supplements. Black cohosh is one of them.</p> <h2>What causes hot flushes</h2> <p>The cause of hormonal hot flushes (also called hot flashes) still isn’t completely understood, but the decline in oestrogen at menopause appears to play a role in a process that involves the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3833827/">area of the brain that regulates temperature</a> (the hypothalamus).</p> <p>Factors linked to a greater likelihood of hot flushes include <a href="https://pubmed.ncbi.nlm.nih.gov/19675142/">being overweight or having obesity</a> and <a href="https://pubmed.ncbi.nlm.nih.gov/25706184/">smoking</a>.</p> <p>MHT, previously known as hormone replacement therapy (HRT), usually includes oestrogen and is the <a href="https://pubmed.ncbi.nlm.nih.gov/26444994/">most effective treatment</a> for menopausal symptoms, such as hot flushes. But women may choose complementary and alternative medicines instead – either because they shouldn’t take hormone therapy, for example because they have breast cancer, or because of personal preference.</p> <p>Close <a href="https://pubmed.ncbi.nlm.nih.gov/26224187/">to 40%</a> of Australian women report using complementary and alternative medicines for menopausal symptoms, and up to 20% using them specifically to treat hot flushes and sweats.</p> <h2>A long history</h2> <p>Complementary and alternative medicines have a long history of use in many cultures. Today, their potential benefits for menopausal symptoms are promoted by the companies that make and sell them.</p> <p>The <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6419242/">complementary and alternative medicines</a> women often try for menopausal symptoms include phytoestrogens, wild yam, dong quai, ginseng and black cohosh.</p> <p>Black cohosh (plant name <em>Cimicifuga racemosa</em>) was <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6599854/">traditionally</a> used by Native Americans to treat a variety of health concerns such as sore throat, kidney trouble, musculoskeletal pain and menstrual problems. It is now a popular herbal choice for hot flushes and night sweats, as well as vaginal dryness and mood changes.</p> <p>There are <a href="https://pubmed.ncbi.nlm.nih.gov/37252752/">many theories</a> for how the active ingredients in black cohosh might work in the body, such as acting like oestrogen, or affecting chemical pathways in the brain. But despite extensive research, the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6599854/">evidence to support these theories remains inconclusive</a>.</p> <p>It is also not clear whether black cohosh is effective for hot flushes. Results from individual studies are mixed, with <a href="https://pubmed.ncbi.nlm.nih.gov/17565936/">some</a> finding black cohosh improves hot flushes, while <a href="https://pubmed.ncbi.nlm.nih.gov/18257142/">others</a> have found it doesn’t.</p> <p>A 2012 <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6599854/">review</a> combined all the results from studies of menopausal women using black cohosh to that date and found overall there was no proof black cohosh reduces hot flushes more effectively than an inactive treatment (placebo). <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6599854/">This review</a> also revealed that many studies did not use rigorous research methods, so the findings are hard to interpret.</p> <p>A more recent <a href="https://pubmed.ncbi.nlm.nih.gov/33021111/">review</a> of clinical trials claimed black cohosh may ease menopausal symptoms, but the included studies were mostly small, less than six months long, and included women with mild symptoms.</p> <p>There is also no meaningful evidence black cohosh helps other symptoms of menopause, such as vaginal symptoms, sexual problems, or poor general wellbeing, or that it protects against bone loss.</p> <p>Evidence for how black cohosh is absorbed and metabolised by the body is also lacking, and it is not known what dose or formulation is best to use.</p> <p>More good quality studies are needed to decide whether black cohosh works for hot flushes and other menopausal symptoms.</p> <h2>Is it safe to try?</h2> <p>A <a href="https://pubmed.ncbi.nlm.nih.gov/33021111/">review of studies</a> suggests black cohosh is safe to use, although many of the studies have not reported possible adverse reactions in detail. Side effects such as gastrointestinal upset and rashes may occur.</p> <p>While there have been <a href="https://www.mja.com.au/journal/2008/188/7/liver-failure-associated-use-black-cohosh-menopausal-symptoms#0_i1091948">rare reports of liver damage</a>, there is <a href="https://pubmed.ncbi.nlm.nih.gov/21228727/">no clear evidence</a> black cohosh was the cause. Even so, in Australia, black cohosh manufacturers and suppliers are required to put a warning label for the potential of harm to the liver on their products.</p> <p>It is recommended black cohosh is not used by women with menopausal symptoms <a href="https://www.canceraustralia.gov.au/cancer-types/breast-cancer/impacted-by-breast-cancer/physical-changes/menopause/treatments-menopausal-symptoms">after breast cancer</a>, as its safety after breast cancer is uncertain. All women should consult with their doctor before using black cohosh if they are taking other medications in case of possible drug interactions.</p> <p>Many women like to try herbal therapies for hot flushes and other menopausal symptoms. While black cohosh is generally considered safe and some women may find it helps them, at the moment there is not enough scientific evidence to show its effects are any better than placebo.</p> <p>Women experiencing troublesome menopausal symptoms, such as hot flushes, should talk to their doctor about the best treatment options for them.<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/211272/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/sasha-taylor-1461085"><em>Sasha Taylor</em></a><em>, Research fellow, Chronic Disease &amp; Ageing, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> and <a href="https://theconversation.com/profiles/susan-davis-10376">Susan Davis</a>, Chair of Women's Health, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a></em></p> <p><em>Image credits: Getty </em><em>Images </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Princess Di's black sheep jumper sells for 14 times over asking price

<p>Princess Diana's famous "black sheep" jumper has sold at auction for more than $1.1million.   </p> <p>The iconic red and white (and one tiny bit of black, of course!) jumper fetched precisely $1,143,000 at Sotheby's in New York - making it the most expensive piece of clothing owned by the former Princess of Wales to sell at auction, as well as the most expensive jumper to ever be sold at auction. </p> <p>There were a total of 44 bids within the final 15 minutes of a two-week online bidding process for the famous item of clothing - during which the bidding leapt from $190,000 to $1,143,000, which ultimately pushed the sale to a staggering 14 times over the initial asking price of $80,000.  </p> <p>The woollen jumper was worn by Lady Di to a polo match in Windsor in June 1981, just one month before she married the then-Prince Charles. </p> <p>Soon after Diana wore the garment, it was returned to Sally Muir and Joanna Osborne, founders of the label Warm &amp; Wonderful because of a tear at the cuff.</p> <p>It was sent back to the designers along with a note from Buckingham Palace, requesting that the jumper be either repaired or replaced.</p> <p>A new jumper was knitted for Diana, with Osborne believing the original garment had been lost after the replacement was sent to the Princess of Wales, which she wore to another polo match in 1983. </p> <p>However, Osborne later discovered the jumper, which had been preserved underneath an old cotton bedspread, while searching her attic looking for an old pattern. </p> <p>She got in touch with Sotheby's auction house which gave the garment an auction estimate of around $80,000 - $120,000.</p> <p>Speaking to <em>The Telegraph UK</em>, Osborne said, "We didn't think we had any of the original sheep jumpers, because at the time, we were so desperate to complete orders that we never owned one ourselves, so I couldn't believe I'd found the original Diana sheep jumper."</p> <p>"It took a while to sink in. And we're so lucky it's not fallen to pieces."</p> <p>Sotheby's said of the now-iconic design, "The Black Sheep sweater is one of the most iconic pieces worn by Princess Diana to ever come to market."</p> <p>"The cultural impact of this moment from the 1980s is exemplified by the head of Rowing Blazers, Jack Carlson, who in 2020, requested to partner with the original designers and license the sheep design to be reproduced for his own fashion line."</p> <p>"Since stumbling upon the sweater ... we have been reliving the fond memories of Princess Diana appearing on the front pages of every newspaper in 1981, wearing our very own sweater.  </p> <p>"While we are forever indebted to her for the impact this had on our business, our deepest appreciation lies in the knowledge that she shared a unique connection to the black sheep design. We are thrilled that this cherished sweater has now found a new home, carrying with it the enduring legacy of Princess Diana."</p> <p><em>Images: Getty</em></p>

<p><em><a href="https://theconversation.com/profiles/nial-wheate-96839">Nial Wheate</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> and <a href="https://theconversation.com/profiles/jessica-pace-1401278">Jessica Pace</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>Social media is lighting up over what influencers are calling “<a href="https://www.forbes.com/sites/brucelee/2023/09/09/budget-ozempic-tiktok-trend-how-its-contributing-to-the-laxative-shortage/?sh=1f54511b1569">budget Ozempic</a>”. These are drugs normally used as laxatives and stool softeners, but people are taking them to lose weight. The demand is so high in the United States, there are reports this is contributing to <a href="https://www.wsj.com/health/wellness/laxative-shortage-diet-weight-loss-5a15bf02">shortages</a> in pharmacies.</p> <p>These laxatives are just the latest alternatives influencers are touting for the <a href="https://www.abc.net.au/news/2023-09-09/ozempic-maker-novo-nordisk-becomes-biggest-company-in-europe/102812584">blockbuster drug</a> Ozempic.</p> <p>So, does “budget Ozempic” help you lose weight? Any weight loss is likely to be temporary and using these laxatives long term may be dangerous.</p> <h2>Ozempic is in short supply</h2> <p>Ozempic contains the active ingredient semaglutide. It is a prescription-only drug used to treat type 2 diabetes. One side effect of taking it is significant weight loss. This has led to so many people trying to obtain the drug there have been <a href="https://www.tga.gov.au/safety/shortages/information-about-major-medicine-shortages/about-ozempic-semaglutide-shortage-2022-and-2023">shortages</a>.</p> <p>Instead, some people have turned to more easily accessible over-the-counter alternatives to try to lose weight. That includes <a href="https://theconversation.com/natures-own-ozempic-or-berberine-is-all-over-social-media-but-does-it-really-help-you-lose-weight-206855">berberine</a>, which has been dubbed “nature’s own Ozempic”.</p> <h2>What is ‘budget Ozempic’?</h2> <p>“Budget Ozempic” is different to “nature’s own Ozempic”. It is the polymer polyethylene glycol 3350, or PEG 3350 for short.</p> <p>Chemically, it’s similar to other polymers used as ingredients in cosmetics, drug delivery, <a href="https://www.chemistryworld.com/features/raiders-of-the-lost-pigments/3007237.article">archaeological preservative paints</a>, soaps and even <a href="https://navyrecognition.com/index.php/naval-news/naval-news-archive/2023/june/13261-northrop-grumman-hits-production-milestone-with-trident-ii-d5-s-2000th-rocket-motor.html">missile fuel</a>. It’s not to be confused with ethylene glycol, which is used in antifreeze.</p> <p>Medically, PEG 3350 is mainly sold in Australia through pharmacies in <a href="https://australianprescriber.tg.org.au/articles/managing-constipation-in-adults.html">laxative and stool softening</a> products. It is also used to clean out your bowels before a colonoscopy.</p> <p>The products are referred to as <a href="https://www.healthdirect.gov.au/medicines/medicinal-product/aht,22630/macrogol-3350">macrogols</a>. Brands include DulcoSoft, Movicol, OsmoLax, ClearLax and ColonLYTELY.</p> <h2>How can it cause weight loss?</h2> <p>PEG 3350 is known as an <a href="https://www.nhs.uk/conditions/laxatives/#:%7E:text=Osmotic%20laxatives%20draw%20water%20from,brand%20names%20Duphalac%20and%20Lactugal">osmotic laxative</a>. It uses osmosis – how your body manages the balance of electrolytes in your blood serum – to soften your stools and treat constipation.</p> <p>When you swallow a drink with PEG 3350 the polymer isn’t absorbed by the body. Instead, as it passes through your intestines it draws water to it, making your faeces much more watery.</p> <p>Because it draws more water out of your body than you put into it from the drink, your weight goes down. That is, it just makes you dehydrated.</p> <p>This means any weight loss is likely to be short-lived; when you next drink, your body will retain more of the water to replace what was lost. To have any significant and sustained weight loss you’d need to take a lot of PEG 3350 every day. And at most, you would only lose a few kilograms.</p> <p>This is different to how <a href="https://www.nps.org.au/assets/medicines/42ccacc2-2326-42ad-ad14-abd6010499a4.pdf">Ozempic</a> works. Ozempic is similar to a family of hormones in your body called <a href="https://pubmed.ncbi.nlm.nih.gov/29364588/">incretins</a>. These have a number of actions that control both blood sugar levels and weight. For example, they slow how quickly food is absorbed from the stomach and decrease appetite, both of which help with sustained weight loss.</p> <h2>Dangers and side effects</h2> <p>PEG 3350 can make you <a href="https://www.healthdirect.gov.au/dehydration">dehydrated</a>. You may feel dizzy or light-headed, have a headache and have a dry mouth, lips or eyes.</p> <p>The concentration of electrolytes in your blood, such as salt, may also be too high (known as hypertonic blood serum).</p> <p>Hypertonic blood serum can affect the shape of your red blood cells, making it harder for them to carry oxygen around your body. This results in symptoms that include fatigue and tiredness, and those other symptoms of being dehydrated. In extreme cases it can result in <a href="https://psmf.org/story/emily-jerry/">death</a>.</p> <p>Incorrect levels of electrolytes can lead to other serious problems, affecting your heart and muscles. It can also lead to seizures, confusion, and coma.</p> <p>It can be dangerous to take PEG 3350 if you have heart disease, if your doctor has put you on a sodium-restricted diet, or if you already have an electrolyte disorder, such as <a href="https://www.healthdirect.gov.au/potassium">hyperkalaemia</a> (high potassium levels).</p> <p>These products are also dangerous for elderly people, those with kidney problems, and in very young children.</p> <p>Common side effects include anal irritation, vomiting, diarrhoea, nausea, cramps, pain, and swelling of your abdomen. Some people can have allergic reactions.</p> <p>If you use laxatives, including PEG 3350-based products, for a long period of time (over a period of weeks or months) then you may experience <a href="https://www.eatingdisorders.org.au/wp-content/uploads/2019/10/Eating-disorders-and-laxatives.pdf">withdrawal symptoms</a> if you stop taking them suddenly. These include constipation, bloating, weight gain and fluid retention.</p> <h2>In a nutshell</h2> <p>Overall, if you’ve been struggling with weight loss, then PEG 3350-based products are not a safe and effective solution. Any weight loss you experience will be temporary and may put your health at risk. Safer and more effective solutions are available.</p> <p>Eating healthily and exercising regularly are important first steps for anyone who wishes to lose weight. Otherwise, your GP or local pharmacist can help you with both lifestyle changes and medication options to help with weight loss.<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/213457/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/nial-wheate-96839">Nial Wheate</a>, Associate Professor of the Sydney Pharmacy School, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> and <a href="https://theconversation.com/profiles/jessica-pace-1401278">Jessica Pace</a>, Associate Lecturer, Sydney Pharmacy School, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p><em>Image credits: Getty Images</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

5 tips for getting off gas at home – for a cleaner, cheaper, healthier all-electric future

<p><a href="https://theconversation.com/profiles/trivess-moore-12580">Trivess Moore</a>, <em><a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a></em>; <a href="https://theconversation.com/profiles/alan-pears-52">Alan Pears</a>, <em><a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a></em>, and <a href="https://theconversation.com/profiles/nicola-willand-441807">Nicola Willand</a>, <em><a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a></em></p> <p>Burning gas in our homes to cook food or heat air and water has become a contentious issue. Gas is an expensive, polluting fossil fuel, and there’s mounting evidence to suggest it’s also <a href="https://www1.racgp.org.au/ajgp/2022/december/health-risks-from-indoor-gas-appliances">bad for our health</a>.</p> <p>Five million existing Australian households will need to <a href="https://grattan.edu.au/report/getting-off-gas/">get off gas</a> within the next 30 years. But for homeowners, the upfront cost can be a major barrier to action. Renters rarely get a say over the appliances installed in their homes. And apartment owners can struggle to make individual changes too.</p> <p>In most cases it’s worth making the switch, for the energy bill savings alone. For example, analysis suggests a household in Melbourne switching from gas to electricity can save <a href="https://theconversation.com/all-electric-homes-are-better-for-your-hip-pocket-and-the-planet-heres-how-governments-can-help-us-get-off-gas-207409">up to A$13,900</a> over a decade.</p> <p>If you’re contemplating upgrading gas appliances in your home, or even disconnecting from the gas network altogether, here are a few handy tips and resources to cut through the confusion.</p> <figure><iframe src="https://www.youtube.com/embed/2JuZgXz6zNo?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">Homes must switch away from gas by 2050, says policy think tank (ABC News)</span></figcaption></figure> <h2>Tip 1 – Find trusted, independent information</h2> <p>There is no shortage of information on how to make the switch from gas to all-electric appliances. The challenge is finding <a href="https://theconversation.com/we-need-a-lemon-law-to-make-all-the-homes-we-buy-and-rent-more-energy-efficient-204369">trusted and independent information</a>.</p> <p>Not-for-profit organisation <a href="https://renew.org.au/">Renew</a> has compiled a range of <a href="https://renew.org.au/resources/how-we-can-help/efficient-electric-homes/how-we-can-help-going-off-gas/">presentations, guides, case studies and research</a>. <a href="https://www.choice.com.au/">Choice</a> provides independent reviews of household appliances, including operating costs. The Australian government’s <a href="https://www.energyrating.gov.au/">Energy Rating website</a> provides information on appliances to help consumers compare performance. Some <a href="https://www.yarracity.vic.gov.au/services/take-climate-action">local councils</a> and <a href="https://totallyrenewableyack.org.au/">community groups</a> also provide information, support and bulk-buying schemes.</p> <p>You could also visit some of the all-electric homes open to the public for <a href="https://sustainablehouseday.com/">Sustainable House Day</a>. This can help you learn what works from people who have already made the change.</p> <p>The <a href="https://www.facebook.com/groups/MyEfficientElectricHome">My Efficient Electric Home</a> group on Facebook is another active and helpful forum.</p> <p>If you are going all-electric as part of a wider retrofit, consider an independent <a href="https://www.homescorecard.gov.au/">Residential Efficiency Scorecard assessment</a>. This will help you understand what to else you can do to maximise <a href="https://theconversation.com/the-other-99-retrofitting-is-the-key-to-putting-more-australians-into-eco-homes-91231">thermal comfort, environmental benefits and financial outcomes</a>.</p> <h2>Tip 2 – Plan your approach</h2> <p>Once you understand what to do, the next step is planning how to go about it. Think about what is most important to your household. What is driving the change? If it’s your health, you might like to start by eliminating indoor air pollution from the gas stove. Or if you want to save money, start using reverse-cycle air conditioning to heat your home, rather than gas.</p> <p>There are three main ways to go all-electric:</p> <ul> <li> <p><strong>Replace all your gas appliances at once</strong>. Making the change quickly minimises disruption to your home. You may save money on installation costs by doing everything in one go. You will avoid ongoing fixed gas supply charges once you disconnect from the gas network, but you may be required to pay an “<a href="https://energy.act.gov.au/switching-off-your-gas-connection/">abolishment fee</a>” for permanent disconnection. That fee can vary significantly, depending on your location and gas provider. Costs <a href="https://www.smh.com.au/environment/sustainability/would-you-pay-1000-to-get-off-gas-consumer-dismay-over-disconnection-cost-20230223-p5cmw9.html">could be up to $1000 (or more)</a> but some states like Victoria have capped the price a <a href="https://reneweconomy.com.au/fossil-gas-death-spiral-regulator-sets-exit-fee-to-socialise-cost-of-mass-disconnection/">household can be charged at $220</a>. Renters wouldn’t be able to permanently disconnect without permission from the landlord, so they would still be open to paying the daily connection fee even if they found alternative electric options for everything else.</p> </li> <li> <p><strong>Replace your gas appliances one at a time</strong>, as finances allow. However, there will come a point where <a href="http://www.ata.org.au/wp-content/projects/CAP_Gas_Research_Final_Report_251114_v2.0.pdf">financially you will be better off</a> replacing all the remaining gas appliances. This is largely because it will not be affordable to keep paying the daily connection cost for gas if you just have one gas appliance remaining.</p> </li> <li> <p><strong>Just stop using gas appliances</strong> in favour of existing electric appliances that do the same job, such as a <a href="https://reneweconomy.com.au/the-traps-laid-by-the-fossil-gas-industry-for-uninformed-households/">reverse cycle air conditioner for space heating</a>. You may have – or can buy – plug-in electric alternatives, such as a microwave ovens, portable induction cooktops, air fryers and heaters. These can be a good option for renters when landlords won’t make changes.</p> </li> </ul> <p>You could even borrow portable appliances to see how they work before committing to buying your own.</p> <figure><iframe src="https://www.youtube.com/embed/tLjWZicC4mE?wmode=transparent&amp;start=2" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">Households share their electrification journey (Renew)</span></figcaption></figure> <h2>Tip 3 – Access available rebates and resources</h2> <p>Most states offer various rebates for households to reduce the upfront cost of replacing gas appliances. These could reduce costs by thousands of dollars. Some rebates also target rental housing. Here is a list of key rebates available in different states:</p> <ul> <li><a href="https://www.epw.qld.gov.au/about/initiatives/household-energy-savings-program">Queensland</a></li> <li><a href="https://www.energy.nsw.gov.au/households/rebates-grants-and-schemes">New South Wales</a></li> <li><a href="https://www.climatechoices.act.gov.au/policy-programs/home-energy-support-rebates-for-homeowners">ACT</a></li> <li><a href="https://www.energy.vic.gov.au/for-households/victorian-energy-upgrades-for-households">Victoria</a></li> <li><a href="https://recfit.tas.gov.au/household_energy/energy_saver_loan_scheme">Tasmania</a></li> <li><a href="https://www.sa.gov.au/topics/energy-and-environment/using-saving-energy/retailer-energy-productivity-scheme">South Australia</a></li> </ul> <p>Some not-for-profit organisations (such as the <a href="https://www.bsl.org.au/services/energy-assistance/">Brotherhood of St Laurence</a>) offer financial and other support for lower-income households struggling to pay their energy bills.</p> <h2>Tip 4 – Wait for a sale or negotiate a better deal</h2> <p>It might sound simple but you can always save money by waiting until these electric appliances are on sale. If you are buying multiple appliances you can try to negotiate a better price. Factory seconds outlets offer lower prices as well.</p> <h2>Tip 5 – Know the issues</h2> <p>While the shift to all-electric will likely provide many benefits there are some things you need to consider:</p> <ul> <li>The carbon emissions from electricity are falling fast, and many homes have rooftop solar. Combining <a href="https://grattan.edu.au/report/getting-off-gas/">all-electric with solar panels</a> will maximise returns.</li> <li>You may have to adjust to how new technologies operate and perform. For example, you may need <a href="https://www.theage.com.au/goodfood/tips-and-advice/do-you-really-have-to-buy-new-cookware-all-your-burning-questions-about-induction-cooking-answered-20230810-p5dvd0.html">new, metallic cookware for an induction cooktop</a> and become familiar with their fast response. Additionally, some people find heat from reverse cycle air conditioners to be drier and/or draughtier than gas heating. Floor-mounted units heat more effectively.</li> <li>It is not just the energy performance of appliances that matters. For example, noise from heat pump hot water services can vary across different brands. They can also require more space for installation.</li> <li>Undertaking a wider energy retrofit (for example, increasing insulation in walls, ceiling and underfloor, upgrading windows to double glazing) may mean you can buy a smaller, cheaper reverse cycle air conditioner when replacing gas heating.</li> <li>Electric appliances also need maintenance to make sure they perform optimally. For example, reverse cycle air conditioners have filters that must be regularly cleaned. While this can be done by households, it can be hard for people with mobility issues.</li> <li>Depending on the capacity of your electricity switchboard or wiring, extra electric appliances may require upgrades.</li> <li>For renters, while you could use portable appliances, you may not be able to disconnect from gas completely, meaning you would still have to pay a daily connection fee.</li> <li>Gas and electricity prices can change over time, for many reasons. For example, if fixed gas distribution costs are spread over fewer customers.</li> </ul> <h2>A worthwhile investment</h2> <p>Australian states and territories have started banning gas in new builds. Victoria and the ACT will soon require <a href="https://theconversation.com/cooking-and-heating-without-gas-what-are-the-impacts-of-shifting-to-all-electric-homes-210649">new housing and major renovations to be all-electric</a>. Others are likely to follow.</p> <p>For people in existing housing around Australia, it can be daunting to make the switch. Many of us have grown up with gas in our homes and when one appliance breaks, the easiest thing to do is replace like-for-like. But the weight of evidence shows it’s worth taking the time to look at the alteratives and invest in upgrading to all-electric appliances. The benefits far outweigh the costs. <!-- Below is The Conversation's page counter tag.

Don’t believe the hype. Menopausal women don’t all need to check – or increase – their testosterone levels

<p><em><a href="https://theconversation.com/profiles/susan-davis-10376">Susan Davis</a>, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a></em></p> <p>Ever heard “low testosterone” blamed for low mood, brain fog and loss of vitality? Despite all evidence to the contrary, social media influencers are increasingly promoting testosterone therapy as an elixir for women experiencing troubling symptoms of menopause.</p> <p>In a series of documentaries and <a href="https://www.dailymail.co.uk/health/article-11792553/Davina-McCall-effect-sparks-menopause-testosterone-treatment-rush-putting-women-risk.html">social media posts</a> about menopause in 2021 and 2022, British TV presenter Davina McCall promoted the use of testosterone therapy in addition to standard <a href="https://www.menopause.org.au/hp/information-sheets/combined-menopausal-hormone-therapy-mht">menopausal hormone therapy</a>. The “<a href="https://www.telegraph.co.uk/news/2023/02/17/davina-effect-fuels-surge-menopausal-women-using-testosterone/#:%7E:text=Chelsea%20Magazine%20Company-,'Davina%20effect'%20fuels%20surge%20in%20menopausal%20women%20using%20testosterone,NHS%20prescriptions%20for%20the%20hormone">Davina effect</a>” has helped fuel a <a href="https://pharmaceutical-journal.com/article/news/nhs-testosterone-prescribing-in-women-rises-ten-fold-in-seven-years#:%7E:text=The%20number%20of%20women%20in,The%20Pharmaceutical%20Journal%20has%20revealed">ten-fold increase</a> in prescribing of testosterone for women in the United Kingdom since 2015.</p> <p>Data isn’t available for Australia, but in my clinical practice, women are increasingly asking to have their testosterone level checked, and seeking testosterone to treat fatigue and brain fog.</p> <p>But while testosterone continues to be an important hormone before and after menopause, this doesn’t mean women should be having a blood test to get their testosterone levels checked – or taking testosterone therapy.</p> <h2>What does testosterone do?</h2> <p>Testosterone is an important hormone in women’s bodies, affecting the blood vessels, skin, muscle and bone, breast tissue and the brain. In both women and men, testosterone can act on its own or be converted into estrogen.</p> <p>Before menopause, testosterone is made in the ovaries, where it helps developing eggs grow and aids in estrogen production.</p> <p>The ovaries release both testosterone and estrogen into the bloodstream, and the levels of the two hormones in the blood peak around ovulation.</p> <p>Some of the testosterone measured in blood is also produced outside the ovaries, such as in fat, where it is made from “pre-hormones” secreted by the adrenal glands. This source of production of testosterone takes over after menopause.</p> <h2>Do we have more testosterone before menopause?</h2> <p>The claim is often made that pre-menopausal women have more testosterone in their bloodstream than estrogen, to justify the need for testosterone replacement after menopause.</p> <p>But, when sex hormones have been measured with precision, studies have shown this is not true. <a href="https://pubmed.ncbi.nlm.nih.gov/31390028/">Our research</a> found estrogen levels are higher than testosterone levels at all stages of the menstrual cycle.</p> <p>Blood testosterone levels <a href="https://pubmed.ncbi.nlm.nih.gov/31390028/">fall</a> by about 25% between the ages of 18 and 40 years in healthy women. The fall in testosterone coincides with the decline in eggs in the ovaries but whether this is a marker of the decline, a consequence, or a cause of the decline is not known.</p> <p>From around 40, the rate of decline slows and blood testosterone levels don’t change when <a href="https://www.menopause.org.au/hp/information-sheets/what-is-menopause">menopause</a> occurs naturally. Studies have not shown testosterone levels change meaningfully during the menopause transition.</p> <h2>Can blood tests detect ‘low testosterone’?</h2> <p>Some influencers claim to have a condition called “testosterone deficiency syndrome” or low levels of testosterone detected in blood tests.</p> <p>But there is no “normal” blood level below which a woman can be diagnosed as having “testosterone deficiency”. So there’s no such thing as having a testosterone deficiency or testosterone deficiency syndrome.</p> <p>This is also in part, because women have very low testosterone concentrations compared with men, and most commercial methods used to measure testosterone cannot separate normal from low levels in women with any certainty.</p> <p>Pre-menopausal women might also be told they have “low” testosterone if blood is drawn early in the menstrual cycle when it is normal for testosterone to be low. (However, it would only be clinically necessary to do this type of blood test to look for <em>high</em> testosterone, in someone with with excessive hair growth or severe acne, for example, not for <em>low</em> testosterone.)</p> <p>In post-menopausal women, much of the action of testosterone occurs in the tissues where it is made, after which testosterone is either converted to estrogen or broken down before it leaks back into the circulation. So blood testosterone concentrations are not a true reflection of tissue concentrations.</p> <p>Further complicating the picture is the enormous variability in the effects of testosterone. At a given blood level of testosterone, some women might have oily skin, acne, increased body hair growth or balding, while others will have no such effects.</p> <p>So, looking for a “low” blood testosterone in women is not helpful.</p> <h2>Can testosterone improve sexual desire? What about other conditions?</h2> <p>There is sound evidence that testosterone therapy may improve sexual desire in post-menopausal women who have developed low sexual desire that bothers them.</p> <p>This was <a href="https://www.tandfonline.com/doi/full/10.1080/13697137.2019.1637079">confirmed by</a> a <a href="https://pubmed.ncbi.nlm.nih.gov/31353194/">systematic review</a> of clinical trials comparing testosterone with a placebo or an alternative. These trials, all of which involved a treatment time of at least 12 weeks, showed testosterone therapy, overall, improved desire, arousal, orgasm and sexual satisfaction in post-menopausal women with low desire that caused them distress.</p> <p>Treatment is only indicated for women who want an improvement in sexual desire (after excluding other factors such as depression or medication side effects) and its success can only be determined by each woman’s personal self-reported response.</p> <p>But there is <a href="https://www.tandfonline.com/doi/full/10.1080/13697137.2019.1637079">not enough evidence</a> to show testosterone is beneficial for any other symptom or medical condition.

Not all mental health apps are helpful. Experts explain the risks, and how to choose one wisely

<p><em><a href="https://theconversation.com/profiles/jeannie-marie-paterson-6367">Jeannie Marie Paterson</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a>; <a href="https://theconversation.com/profiles/nicholas-t-van-dam-389879">Nicholas T. Van Dam</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a>, and <a href="https://theconversation.com/profiles/piers-gooding-207492">Piers Gooding</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a></em></p> <p>There are thousands of mental health apps available on the app market, offering services including meditation, mood tracking and counselling, among others. You would think such “health” and “wellbeing” apps – which often present as solutions for conditions such as <a href="https://www.headspace.com/">anxiety</a> and <a href="https://www.calm.com">sleeplessness</a> – would have been rigorously tested and verified. But this isn’t necessarily the case.</p> <p>In fact, many may be taking your money and data in return for a service that does nothing for your mental health – at least, not in a way that’s backed by scientific evidence.</p> <h2>Bringing AI to mental health apps</h2> <p>Although some mental health apps connect users with a <a href="https://www.betterhelp.com/get-started/?go=true&amp;utm_source=AdWords&amp;utm_medium=Search_PPC_c&amp;utm_term=betterhelp+australia_e&amp;utm_content=133525856790&amp;network=g&amp;placement=&amp;target=&amp;matchtype=e&amp;utm_campaign=15228709182&amp;ad_type=text&amp;adposition=&amp;kwd_id=kwd-401317619253&amp;gclid=Cj0KCQjwoeemBhCfARIsADR2QCtfZHNw8mqpBe7cLfLtZBD-JZ5xvAmDCfol8npbAAH3ALJGYvpngtoaAtFlEALw_wcB¬_found=1&amp;gor=start">registered therapist</a>, most provide a fully automated service that bypasses the human element. This means they’re not subject to the same standards of care and confidentiality as a registered mental health professional. Some aren’t even designed by mental health professionals.</p> <p>These apps also increasingly claim to be incorporating artificial intelligence into their design to make personalised recommendations (such as for meditation or mindfulness) to users. However, they give little detail about this process. It’s possible the recommendations are based on a user’s previous activities, similar to Netflix’s <a href="https://help.netflix.com/en/node/100639">recommendation algorithm</a>.</p> <p>Some apps such as <a href="https://legal.wysa.io/privacy-policy#aiChatbot">Wysa</a>, <a href="https://www.youper.ai/">Youper</a> and <a href="https://woebothealth.com/">Woebot</a> use AI-driven chatbots to deliver support, or even established therapeutic interventions such as cognitive behavioural therapy. But these apps usually don’t reveal what kinds of algorithms they use.</p> <p>It’s likely most of these AI chatbots use <a href="https://www.techtarget.com/searchenterpriseai/feature/How-to-choose-between-a-rules-based-vs-machine-learning-system">rules-based systems</a> that respond to users in accordance with predetermined rules (rather than learning on the go as adaptive models do). These rules would ideally prevent the unexpected (and often <a href="https://www.vice.com/en/article/pkadgm/man-dies-by-suicide-after-talking-with-ai-chatbot-widow-says">harmful and inappropriate</a>) outputs AI chatbots have become known for – but there’s no guarantee.</p> <p>The use of AI in this context comes with risks of biased, discriminatory or completely inapplicable information being provided to users. And these risks haven’t been adequately investigated.</p> <h2>Misleading marketing and a lack of supporting evidence</h2> <p>Mental health apps might be able to provide certain benefits to users <em>if</em> they are well designed and properly vetted and deployed. But even then they can’t be considered a substitute for professional therapy targeted towards conditions such as anxiety or depression.</p> <p>The <a href="https://theconversation.com/pixels-are-not-people-mental-health-apps-are-increasingly-popular-but-human-connection-is-still-key-192247">clinical value</a> of automated mental health and mindfulness apps is <a href="https://www.sciencedirect.com/science/article/abs/pii/S1077722918300233?casa_token=lwm1E6FhcG0AAAAA:saV7szbZl4DqbvmZiomLG9yMWi_4-zbmy3QCtQzVEQr957QX1E7Aiqkm5BcEntR0mVFgfDVo">still being assessed</a>. Evidence of their efficacy is generally <a href="https://journals.plos.org/digitalhealth/article?id=10.1371/journal.pdig.0000002">lacking</a>.</p> <p>Some apps make ambitious claims regarding their effectiveness and refer to studies that supposedly support their benefits. In many cases these claims are based on less-than-robust findings. For instance, they may be based on:</p> <ul> <li><a href="https://sensa.health/">user testimonials</a></li> <li>short-term studies with narrow <a href="https://www.wired.co.uk/article/mental-health-chatbots">or homogeneous cohorts</a></li> <li><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9533203/">studies involving</a> researchers or funding from the very group <a href="https://www.theguardian.com/us-news/2022/apr/13/chatbots-robot-therapists-youth-mental-health-crisis">promoting the app</a></li> <li>or evidence of the benefits of a <a href="https://www.headspace.com/meditation/anxiety">practice delivered face to face</a> (rather than via an app).</li> </ul> <p>Moreover, any claims about reducing symptoms of poor mental health aren’t carried through in contract terms. The fine print will typically state the app does not claim to provide any physical, therapeutic or medical benefit (along with a host of other disclaimers). In other words, it isn’t obliged to successfully provide the service it promotes.</p> <p>For some users, mental health apps may even cause harm, and lead to increases in the very <a href="https://pubmed.ncbi.nlm.nih.gov/34074221/">symptoms</a> people so often use them to address. The may happen, in part, as a result of creating more awareness of problems, without providing the tools needed to address them.</p> <p>In the case of most mental health apps, research on their effectiveness won’t have considered <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9505389/">individual differences</a> such as socioeconomic status, age and other factors that can influence engagement. Most apps also will not indicate whether they’re an inclusive space for marginalised people, such as those from culturally and linguistically diverse, LGBTQ+ or neurodiverse communities.</p> <h2>Inadequate privacy protections</h2> <p>Mental health apps are subject to standard consumer protection and privacy laws. While data protection and <a href="https://cybersecuritycrc.org.au/sites/default/files/2021-07/2915_cscrc_casestudies_mentalhealthapps_1.pdf">cybersecurity</a> practices vary between apps, an investigation by research foundation Mozilla <a href="https://foundation.mozilla.org/en/privacynotincluded/articles/are-mental-health-apps-better-or-worse-at-privacy-in-2023">concluded that</a> most rank poorly.</p> <p>For example, the mindfulness app <a href="https://www.headspace.com/privacy-policy">Headspace</a> collects data about users from a <a href="https://foundation.mozilla.org/en/privacynotincluded/headspace/">range of sources</a>, and uses those data to advertise to users. Chatbot-based apps also commonly repurpose conversations to predict <a href="https://legal.wysa.io/privacy-policy">users’ moods</a>, and use anonymised user data to train the language models <a href="https://www.youper.ai/policy/privacy-policy">underpinning the bots</a>.</p> <p>Many apps share so-called <a href="https://theconversation.com/popular-fertility-apps-are-engaging-in-widespread-misuse-of-data-including-on-sex-periods-and-pregnancy-202127">anonymised</a> data with <a href="https://www.wysa.com/">third parties</a>, such as <a href="https://www.headspace.com/privacy-policy">employers</a>, that sponsor their use. Re-identification of <a href="https://www.unimelb.edu.au/newsroom/news/2017/december/research-reveals-de-identified-patient-data-can-be-re-identified">these data</a> can be relatively easy in some cases.</p> <p>Australia’s Therapeutic Goods Administration (TGA) doesn’t require most mental health and wellbeing apps to go through the same testing and monitoring as other medical products. In most cases, they are lightly regulated as <a href="https://www.tga.gov.au/how-we-regulate/manufacturing/medical-devices/manufacturer-guidance-specific-types-medical-devices/regulation-software-based-medical-devices">health and lifestyle</a> products or tools for <a href="https://www.tga.gov.au/sites/default/files/digital-mental-health-software-based-medical-devices.pdf">managing mental health</a> that are excluded from TGA regulations (provided they meet certain criteria).</p> <h2>How can you choose an app?</h2> <p>Although consumers can access third-party rankings for various mental health apps, these often focus on just a few elements, such as <a href="https://onemindpsyberguide.org/apps/">usability</a> or <a href="https://foundation.mozilla.org/en/privacynotincluded/categories/mental-health-apps/">privacy</a>. Different guides may also be inconsistent with each other.</p> <p>Nonetheless, there are some steps you can take to figure out whether a particular mental health or mindfulness app might be useful for you.</p> <ol> <li> <p>consult your doctor, as they may have a better understanding of the efficacy of particular apps and/or how they might benefit you as an individual</p> </li> <li> <p>check whether a mental health professional or trusted institution was involved in developing the app</p> </li> <li> <p>check if the app has been rated by a third party, and compare different ratings</p> </li> <li> <p>make use of free trials, but be careful of them shifting to paid subscriptions, and be wary about trials that require payment information upfront</p> </li> <li> <p>stop using the app if you experience any adverse effects.</p> </li> </ol> <p>Overall, and most importantly, remember that an app is never a substitute for real help from a human professional.<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/211513/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/jeannie-marie-paterson-6367">Jeannie Marie Paterson</a>, Professor of Law, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a>; <a href="https://theconversation.com/profiles/nicholas-t-van-dam-389879">Nicholas T.

Surprising facts about Barbie (she’s kept quiet all this time)

<p><strong>1. Her fame is global, but she’s a small town girl.</strong> According to brand lore, Barbara “Barbie” Millicent Roberts was officially born on March 9, 1959, in the fictional town of Willows, Wisconsin.</p> <p><strong>2. She’s just one of seven kids.</strong> Over the years, her siblings for sale have included: Skipper, Stacie, Chelsea, Krissy, Tutti and Todd.</p> <p><strong>3. Barbie digs younger men.</strong> Her longtime BF Ken is two years younger than Barbie, debuting in toy stores in 1961.</p> <p><strong>4. She has had more than 150 careers</strong>, including paleontologist, Canadian Mountie, McDonald’s cashier, Desert Storm medic, business executive, secretary, Catwoman, and, regrettably, rapper.</p> <p><strong>5. She’s been to space three times.</strong> Astronaut Barbie debuted in space in 1965 (four years before the moon landing), then returned in 1986 and 1994.</p> <p><strong>6. Her house is a zoo. </strong>Barbie has owned more than 40 pets, including 21 dogs, 14 horses, three ponies, six cats, a parrot, a chimpanzee, a panda, a lion cub, a giraffe, and a zebra.</p> <p><strong>7. She’s got friends in the fashion industry.</strong> Gucci, Versace, Vera Wang, Dolce &amp; Gabbana, and Givenchy have all contributed designs to Barbie’s wardrobe.</p> <p><strong>8. Her wardrobe is house-sized.</strong> Barbie has had more than one billion outfits (with shoes to match) designed for her.</p> <p><em>Image credits: Shutterstock</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.co.nz/true-stories-lifestyle/entertainment/8-Things-You-Probably-Didnt-Know-About-Barbie" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

Cooking (and heating) without gas: what are the impacts of shifting to all-electric homes?

<p><em><a href="https://theconversation.com/profiles/trivess-moore-12580">Trivess Moore</a>, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a>; <a href="https://theconversation.com/profiles/alan-pears-52">Alan Pears</a>, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a>, and <a href="https://theconversation.com/profiles/joe-hurley-157161">Joe Hurley</a>, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a></em></p> <p>Gas connections for all new housing and sub-divisions will be <a href="https://www.premier.vic.gov.au/new-victorian-homes-go-all-electric-2024">banned in Victoria</a> from January 1 next year. The long-term result of the state government’s significant change to planning approvals will be all-electric housing. The ACT made <a href="https://www.climatechoices.act.gov.au/policy-programs/preventing-new-gas-network-connections">similar changes</a> early this year, in line with a shift away from gas across <a href="https://www.bbc.com/news/science-environment-47559920">Europe</a> and <a href="https://www.theguardian.com/environment/2023/jan/19/gas-stove-culture-war-united-states">other locations</a>, although the NSW Premier Chris Minns has <a href="https://www.theguardian.com/australia-news/2023/jul/31/nsw-wont-ban-gas-in-new-homes-as-premier-declares-i-dont-need-another-complication">baulked</a> at doing the same.</p> <p>Around <a href="https://www.energy.vic.gov.au/renewable-energy/victorias-gas-substitution-roadmap">80% of homes</a> in Victoria are connected to gas. This high uptake was driven by gas being seen as more affordable and sustainable than electricity over past decades. The situation has <a href="https://www.iea.org/events/net-zero-by-2050-a-roadmap-for-the-global-energy-system">changed dramatically</a> as renewable electricity generation increases and <a href="https://www.abc.net.au/news/2023-07-27/aemo-wholesale-electricity-prices-fall-impact-power-bills/102654498">costs fall</a>.</p> <p><a href="https://theconversation.com/all-electric-homes-are-better-for-your-hip-pocket-and-the-planet-heres-how-governments-can-help-us-get-off-gas-207409">Research</a> has suggested for more than a decade that the benefits of all-electric homes <a href="https://bze.org.au/research_release/energy-efficient-buildings-plan/">stack up in many locations</a>. New homes built under mandatory building energy performance standards (increasing from <a href="https://thefifthestate.com.au/innovation/building-construction/victoria-kicks-the-can-down-the-road-again-on-the-national-construction-code/">6 to 7 stars</a> in Victoria in May 2024) need smaller, cheaper heating and cooling systems. Installing reverse-cycle air conditioning for cooling provides a cost-effective heater as a bonus.</p> <p>Savings from not requiring gas pipes, appliances and gas supply infrastructure help to offset the costs of highly efficient electric appliances. Mandating fully electric homes means economies of scale will further reduce costs.</p> <h2>How does this ban help?</h2> <p>To achieve environmentally sustainable development, reforms of planning policy and regulation <a href="https://theconversation.com/sustainable-cities-australias-building-and-planning-rules-stand-in-the-way-of-getting-there-84263">are essential</a> to convert innovation and best practice to mainstream practice. Planning policy is particularly important for apartment buildings and other housing that may be rented or have an owners’ corporation. Retrofits to improve energy efficiency can be difficult in these situations.</p> <p>Banning gas in new and renovated housing will <a href="https://grattan.edu.au/report/getting-off-gas/">cut greenhouse gas emissions</a>. It’s also <a href="https://theconversation.com/gas-cooking-is-associated-with-worsening-asthma-in-kids-but-proper-ventilation-helps-151591">healthier for households</a> and <a href="https://www.sustainability.vic.gov.au/research-data-and-insights/research/research-reports/the-victorian-healthy-homes-program-research-findings">reduces healthcare costs</a> as well as <a href="https://grattan.edu.au/report/getting-off-gas/">energy bills and infrastructure costs</a>. The Victorian government suggests the change will save all-electric households <a href="https://www.premier.vic.gov.au/new-victorian-homes-go-all-electric-2024">about $1,000 a year</a>. Houses with solar will be even better off.</p> <p>The government appears to be offering wide support to ensure these changes happen, but this will need to be monitored closely.</p> <p>Some households will face extra costs for electric appliances and solar panels. The government’s announcement of <a href="https://www.premier.vic.gov.au/new-victorian-homes-go-all-electric-2024">$10 million</a> for Residential Electrification Grants should help with some of these costs while the industry adjusts.</p> <p>There will be impacts and benefits for the local economy. Some jobs may be lost, particularly in the gas appliance and plumbing industry. The government has announced financial support to retrain people and they will still have essential roles in the existing housing sector.</p> <p>Many gas appliances are imported, including ovens, cooktops and instantaneous gas water heaters. Some components of efficient electric products, such as hot water storage tanks, are made locally. Local activities, including distribution, sales, design, installation and maintenance, comprise much of the overall cost.</p> <h2>Challenges of change must be managed</h2> <p>Sustainability benefits will depend on what <a href="https://grattan.edu.au/report/getting-off-gas/">happens with the energy network</a>. We need more renewable energy, energy storage and smarter management of electricity demand.</p> <p>The shift to all-electric homes may mean winter peak demand for heating increases. Energy market operators and governments will have to monitor demand changes carefully to avoid the reliability issues we already see in summer. However, improving energy efficiency, energy storage and demand management will help reduce this load (and household costs).</p> <p>While the benefits are clear for new homes, the changes may <a href="https://www.bsl.org.au/research/publications/enabling-electrification/">increase gas costs and energy poverty</a> for residents of existing housing who don’t shift to efficient electric solutions. The government has reconfirmed financial rebates to help households switch from gas.</p> <p>In addition, existing housing may face building quality and performance issues. Some may require electrical wiring upgrades as part of the transition.</p> <p>Social acceptance of some electric appliances may also be an issue. For example, <a href="https://www.rmit.edu.au/about/schools-colleges/property-construction-and-project-management/research/research-centres-and-groups/sustainable-building-innovation-laboratory/projects/heet-housing-energy-efficiency-transitions">our research</a> has found some households dislike the way heating from reverse cycle air conditioners feels. Others do not like cooking on induction cooktops.</p> <p>Consumer education and modifications to appliances and buildings may be needed to increase acceptance and avoid backlash.</p> <p>Some electric appliances are available overseas but not in Australia. Higher demand may increase the range of imports. For example, floor-mounted heat pumps can make heating feel similar to gas heating while still providing effective cooling.</p> <p>We should not assume electric appliances are all equal. To improve consumer protection, action is needed on weak standards and limited and inconsistent public information. For example, information on noise levels and efficiency under a range of weather conditions must be standardised.</p> <p>Moving housing away from gas is an <a href="https://link.springer.com/book/10.1007/978-981-99-2760-9">important step</a> in the transition to a zero-carbon economy and energy system. Careful management is needed to ensure this transition is effective, accepted and fair.</p> <p>Continued planning reforms are also essential to ensure environmentally sustainable development of housing and communities. Other urgent priorities include urban cooling and greening, and <a href="https://theconversation.com/turning-the-housing-crisis-around-how-a-circular-economy-can-give-us-affordable-sustainable-homes-208745">circular economy approaches</a> to reduce the material and waste impacts of housing and thus the carbon that goes into building and running homes.<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/210649/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/trivess-moore-12580">Trivess Moore</a>, Senior Lecturer, School of Property, Construction and Project Management, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a>; <a href="https://theconversation.com/profiles/alan-pears-52">Alan Pears</a>, Senior Industry Fellow, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a>, and <a href="https://theconversation.com/profiles/joe-hurley-157161">Joe Hurley</a>, Associate Professor, Sustainability and Urban Planning, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a></em></p> <p><em>Image credits: Getty Images</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Daily aspirin doesn’t prevent strokes in older, healthy people after all

<p><em><a href="https://theconversation.com/profiles/nial-wheate-96839">Nial Wheate</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> and <a href="https://theconversation.com/profiles/tina-hinton-329706">Tina Hinton</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>The daily use of <a href="https://www.nps.org.au/australian-prescriber/articles/drugs-in-secondary-stroke-prevention">low dose aspirin</a> has been a mainstay of preventing strokes for decades. While there has always been a risk of bleeding associated with aspirin use, the benefits were thought to outweigh the risk.</p> <p>Now <a href="https://dx.doi.org/10.1001/jamanetworkopen.2023.25803">new research</a> led by Monash University has shown daily, low-dose aspirin doesn’t prevent strokes in relatively healthy people aged over 70. And it increases their risk of bleeding on the brain after falls or other injuries.</p> <p>But if you’re taking aspirin, it doesn’t mean you should abruptly stop. It may still have a role to play in treating people at high risk of stroke. Or, after talking to your doctor, there might be better options available.</p> <h2>Why has aspirin been used to prevent strokes?</h2> <p>Aspirin is an anti-platelet medicine, which is commonly known as a blood-thinner. <a href="https://www.lifeblood.com.au/blood/learn-about-blood/platelets">Platelets</a> are the component of blood primarily responsible for its clotting action. They are what stop you from continuously bleeding any time you have a cut or scrape on your skin.</p> <p>A <a href="https://strokefoundation.org.au/about-stroke/learn/what-is-a-stroke">stroke</a> is when oxygen can’t get into the brain because of a burst or blocked blood vessel. A blockage can occur when platelets in the bloodstream form a clot and it gets stuck in the artery.</p> <p>Because aspirin acts on platelets, it can help prevent the clots that can lead to a stroke.</p> <p>But because aspirin acts on platelets, it can also increase the risk of <a href="https://www.mayoclinic.org/diseases-conditions/heart-disease/in-depth/daily-aspirin-therapy/art-20046797#:%7E:text=While%20daily%20aspirin%20can%20help,of%20developing%20a%20stomach%20ulcer.">unwanted bleeding</a>, usually in the stomach. It can also increase your risk of bleeding more when you have another injury, like hitting your head.</p> <p>Aspirin isn’t just used for the prevention of strokes. It is also the first aid treatment for someone undergoing a <a href="https://www.nps.org.au/australian-prescriber/articles/acute-myocardial-infarction-early-treatment">heart attack</a>.</p> <h2>Findings of the Monash trial</h2> <p>New <a href="https://dx.doi.org/10.1001/jamanetworkopen.2023.25803">research from Australia and the United States</a> reports results from the Aspirin in Reducing Events in the Elderly (ASPREE) trial.</p> <p>The researchers examined the protective use of daily low-dose aspirin (100 mg) in nearly 2,000 people who were aged 70 years and older and had no history of heart disease or stroke and whose blood pressure and cholesterol were well managed.</p> <p>When compared with placebo, aspirin didn’t reduce or increase the risk of stroke. Of the participants who took the aspirin, 195 or 4.6% had a stroke. Of those who took the placebo, 203 people or 4.7% had a stroke.</p> <p>But it did statistically increase the rate of non-stroke bleeding in the participants’ brains, for example when they injured their head. Those on aspirin showed a rate of bleeding in the brain of 1.1% (108 participants) compared with 0.8% (79 people) for those on placebo. This is a relatively, low but serious, risk.</p> <p>These findings are not entirely new. <a href="https://www.nejm.org/doi/full/10.1056/NEJMoa1800722?query=featured_home">Research</a> published five years ago based on the same ASPREE trial showed a similar result: a higher rate of bleeding among those taking low-dose aspirin compared with placebo.</p> <p>However as the study authors note, aspirin continues to be widely used for the prevention of stroke.</p> <h2>What are the study’s limitations?</h2> <p>The researchers examined aspirin in mostly people of white European heritage.</p> <p>So we don’t know whether the results are translatable to people with different ethnic backgrounds. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2594139/">Genetics and ethnicity</a> can significantly impact the efficacy and safety of some drugs.</p> <p>The clinical trial only included people who were not significantly at risk of a stroke, and had no history of heart disease.</p> <p>Younger age groups were not studied either, so we cannot make any conclusions about their use of low dose aspirin to prevent stroke.</p> <p>It’s also possible the potential benefits and risks are different for those who have underlying heart problems or who have previously had a stroke and are therefore at higher risk of another stroke.</p> <h2>I’m taking aspirin, what should I do?</h2> <p>If you’re taking daily low-dose aspirin and are concerned by the results of the study, it’s important you don’t just stop taking your medicine. Speak to your doctor or pharmacist.</p> <p>For people who are at high risk of having a stroke, or have previously had one, low-dose aspirin may remain their treatment of choice despite the slight bleeding risk.</p> <p>If you’re at high risk of bleeding, for example because of falls and other accidents due to advanced age, frailty, or another underlying condition, your doctor may be able to reduce the amount of aspirin you take by adding in <a href="https://www.nps.org.au/australian-prescriber/articles/dipyridamole">dipyridamole</a> or prescribing a different medicine completely, such as <a href="https://www.nps.org.au/australian-prescriber/articles/clopidogrel">clopidogrel</a>.<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/210388/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/nial-wheate-96839">Nial Wheate</a>, Associate Professor of the Sydney Pharmacy School, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> and <a href="https://theconversation.com/profiles/tina-hinton-329706">Tina Hinton</a>, Associate Professor of Pharmacology, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p><em>Image credits: Getty </em><em>Images </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Ready-made foods you should avoid at all costs

<h2>Pasta dishes</h2> <p>Those ready-made spaghetti Bolognese and creamy pasta dishes are comfort foods at their finest, but they’re not the best for your body. Skip the frozen dishes, which tend to be loaded with sodium and fat, and throw your own healthy pasta recipe together, suggests paediatric dietitian Jodi Greebel. Not only is boiling pasta quick and easy, but you also have more control over what goes into the sauce and sides. Load yours up with nutritious veggies and throw in a tin of lentils for a healthier twist on your guilty-pleasure pasta.</p> <h2>Kids’ meals</h2> <p>Parenting is a 24/7 job, and if you cook separate meals for your little ones, sometimes you lack the energy and time. It’s tempting to pop a frozen kids’ meal in the oven and serve dinner 20 minutes later, but that meal probably isn’t something you really want in your child’s belly. “Some meals have more than half the amount of fat a child needs for the whole day,” says Greebel. With just a teensy bit more effort, you can dish up something you can feel confident feeding your child. For standby freezer aisle meals, Greebel recommends baked chicken nuggets with frozen veggies, but fresh food can be just as easy. Pick up a rotisserie chicken to serve with two vegetables – food that will feed not just your children but the adults in the house too. Any leftovers use in tacos for tomorrow night’s meal.</p> <h2>Low-protein veggie burgers</h2> <p>Skipping the traditional cheeseburger for a meatless option can be better for your belly and the planet, but there’s a catch. A lot of people look at all plant-based burgers as healthy protein substitutes, but some are much higher in carbohydrates and fat than protein, says nutrition program creator Ilana Muhlstein. “Protein is important for keeping us full and preventing overeating.” Leave it on the shelf if the nutrition facts say just five grams of protein, and hunt down another veggie patty with ten grams or more, she suggests.</p> <h2>Frozen stir-fries</h2> <p>Frozen meals like stir-fries are loaded with sodium, thanks in part to the sauces they come in. Luckily, a healthier version is just as easy and freezer-friendly. Buy a pack of plain frozen veggies – some stores even sell stir-fry vegetables without the sauce – and throw them in your wok or frying pan with chicken or beef, suggests Greebel. Use just a bit of low-sodium soy or teriyaki sauce to keep the salt to a minimum.</p> <h2>Fried foods</h2> <p>So, how bad are fried foods? Chips and other frozen fried food is tasty, but it shouldn’t be a part of your regular diet. Loaded with sodium and saturated fats, it could increase your risk of heart disease and obesity. Keep some healthier snack options on hand so you’re not tempted by the fried stuff. Throw together a pita pizza instead of frozen pizza, or make chicken tacos.</p> <h2>Two-serving meals</h2> <p>When you’re looking for a quick and healthy single-serving dinner, buyer beware: some frozen foods look reasonable in calories, fat, and sodium at first glance, but they’re actually two servings disguised as one. Double-check the portion size before you dig in to make sure you’re not biting off more than you’d want to chew. Swap the poser out for a single-serving meal, or set half aside for leftovers.</p> <p><em>Image credit: Shutterstock</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.co.nz/kitchen-tips/ready-made-foods-you-should-avoid-at-all-costs" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

5 things we all do wrong in the shower

<p>While showering every day keeps us smelling fresh, it actually disturbs the natural bacteria on our skin and strips it of the oils that keep it supple. In fact, many shower habits can actually be very unhygienic. Experts reveal what we’re doing wrong, and what to do instead.</p> <p><strong>1.  Showering everyday </strong></p> <p>The University of California found that too much washing can actually be bad for you, because it strips away beneficial bugs that the body uses to help ward off infections. Apparently, if we simply wash our hands and below the belt regularly we can skip a full shower every day.</p> <p><strong>2.  Showering for too long </strong></p> <p>Water is an irritant, so the longer you’re in there, the more irritated and dry your skin will become. Oil from the sebaceous glands hydrate the skin, so showering for too long strips it of moisture.</p> <p><strong>3. Rubbing soap on your whole body</strong></p> <p>Soap dislodges dirt and oil from the body, allowing water to wash it away. But the skin on the arms and legs doesn't contain a lot of oil, so cleaning them with soap just makes them dry.  Instead, simply focus on the armpits, buttocks, groin and feet</p> <p><strong>4.  Letting the shower water blast over your face </strong></p> <p>A hot shower can cause and exacerbate fragile capillary networks in the cheeks, leading to unattractive, visible capillary networks and worsened impaired skin conditions, experts warn.</p> <p><strong>5.  Using a pouf </strong></p> <p>Poufs and loofahs are a haven for bacteria — the dead skin cells they scrub so well from our body get caught up in the nooks where bacteria can feed on them. Also, because poufs take time to dry and may well retain dead skin cells, it’s a potential source of infection. To keep it clean, wet your pouf and put it on a medium heat in the microwave for 30 to 60 seconds.</p> <p>How would you feel about skipping your daily shower, like one of these tips suggests?
