How extreme dieting can affect bone health

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/adam-taylor-283950">Adam Taylor</a>, <a href="https://theconversation.com/institutions/lancaster-university-1176">Lancaster University</a> In a recent Instagram post, the actor Jameela Jamil revealed she has poor bone density, despite only being in her 30s. Jamil blamed this finding on 20 years of dieting – urging her followers to be aware of the harms diet culture can do to your health. Bone density is important for many reasons, primarily because it acts as a reservoir for many of the important minerals our bones need to function well. Many factors can affect your bone density – and as Jamil has pointed out, diet is one component that has a significant effect on bone health. Bone is a living tissue. This means our skeleton <a href="https://www.sciencedirect.com/science/article/abs/pii/S1521690X08000869">grows and remodels itself</a> according to the stresses and strains it’s put under. Everything from fractures to exercise require our bones to change their shape or density. This is why a weightlifter’s skeleton is <a href="https://link.springer.com/article/10.1007/BF00298721">much denser</a> than a marathon runner’s. The biggest skeletal changes we experience happen in our younger years. But bones keep changing throughout our lives depending on how active we are, what our diet consists of, and if we’ve suffered an injury or disease. Bones are <a href="https://www.niams.nih.gov/health-topics/what-bone">made of proteins</a>, such as collagen, as well as minerals – largely calcium. This is a <a href="https://www.ncbi.nlm.nih.gov/books/NBK430714/">key mineral</a> for us, as it keeps our bones and teeth strong and helps repair and rebuild any injured bones. But other minerals and vitamins are also important. For example, vitamin D supports calcium, playing a key role in <a href="https://jamanetwork.com/journals/jamapediatrics/fullarticle/2761808">bone mineralisation</a>. This is where calcium <a href="https://www.ncbi.nlm.nih.gov/books/NBK279023/">combines with phosphate</a> in our bones to create the mineral crystal <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7264100/">hydroxyapatite</a>. This crystal is crucial to our bone mineral density (also known as “bone mass”), as it helps bones remodel and maintain their structural strength. <a href="https://www.nhs.uk/conditions/dexa-scan/">Dexa scans</a> – the type of scan Jamil referred to in her post – can measure the density of these crystals in bones. The <a href="https://theros.org.uk/information-and-support/osteoporosis/scans-tests-and-results/bone-density-scan-dxa/">more hydroxyapatite crystals</a> detected, the healthier the bones are. <figure class="align-center "><img src="https://images.theconversation.com/files/591182/original/file-20240430-18-u30byz.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/591182/original/file-20240430-18-u30byz.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=338&fit=crop&dpr=1 600w, https://images.theconversation.com/files/591182/original/file-20240430-18-u30byz.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=338&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/591182/original/file-20240430-18-u30byz.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=338&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/591182/original/file-20240430-18-u30byz.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=424&fit=crop&dpr=1 754w, https://images.theconversation.com/files/591182/original/file-20240430-18-u30byz.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=424&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/591182/original/file-20240430-18-u30byz.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=424&fit=crop&dpr=3 2262w" alt="The interior of bones, showing four depictions of bone density – from healthy to severe osteoporosis." /><figcaption>The more crystals detected, the better your bone density. <a class="source" href="https://www.shutterstock.com/image-illustration/osteoporosis-4-stages-one-picture-3d-524364046">Crevis/ Shutterstock</a></figcaption></figure> We hit peak bone mineral density in our <a href="https://pubmed.ncbi.nlm.nih.gov/35869910/">late teens and early 20s</a>, when our body has grown to full size and our metabolism is working its best. From here, it’s possible to maintain <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5684300/">stable bone mass</a> into your late 30s for women and early 40s for men, with the right diet and activity. But after this point, it begins to decline. <h2>Bone density</h2> We accrue calcium over many years. It initially comes from our mother, then later from our diet. Our body accrues calcium so it can adapt to times when calcium demand is greater than what we can get from our diet – such as during pregnancy, when the foetus needs calcium to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3355895/">build its own bones</a>. However, relying solely on this skeletal calcium reserve can’t be sustained for lengthy or repeated periods, because of how long it takes to be replenished. This is why diet is so important for bone density – and why a poor diet can cause extreme damage, especially when certain food groups or minerals are consistently left out. For instance, studies have shown consuming soft drinks, (<a href="https://pubmed.ncbi.nlm.nih.gov/17023723/">particularly cola</a>), more than four times a week is linked with <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7071508/">lower bone density</a> and increased fracture risk. This is true even after adjusting for many other variables that affect bone density. These carbonated and energy drinks contain <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2966367/">varying levels of vitamins</a> – often with none of the minerals, including calcium, that the body needs to function optimally. This causes the body to draw on its reserves if calcium isn’t being delivered elsewhere in the diet. Diets high in added sugar can also have a detrimental affect on the skeleton. Excess sugar causes inflammation and other physiological changes, such as <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9471313/">obesity</a>. Consuming high amounts of sugar is linked with <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2748414/">reduced calcium intake</a>, especially in children who substitute milk for sugary drinks. Excess sugar consumption also causes the body to <a href="https://jps.biomedcentral.com/articles/10.1007/s12576-016-0487-7">excrete excess calcium</a>, instead of reabsorbing it in the kidney as the body normally would. <a href="https://pubmed.ncbi.nlm.nih.gov/25491765/">Low- and high-fat diets</a> have also been associated with increased risk of <a href="https://www.nhs.uk/conditions/osteoporosis/">osteoporosis</a> (a condition that weakens bones) in women – though larger studies are needed to better understand the effects of removing whole food groups on bone health. <a href="https://www.nhs.uk/mental-health/conditions/anorexia/overview/">Anorexia nervosa</a> also has a significant affect on <a href="https://pubmed.ncbi.nlm.nih.gov/30817009">bone density</a> – affecting a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6959847/">majority of people</a> with the condition. Low bone mineral density – especially in the spine – puts people with anorexia at <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6959847/">increased risk of fractures</a> because their bone thickness is reduced, increasing the likelihood of developing osteoporosis, which is associated with increased fractures. Anorexia in young adulthood is particularly challenging. This is the stage where the skeleton is building itself to reach peak <a href="https://pubmed.ncbi.nlm.nih.gov/15574617/">bone mass</a>, so it’s depositing calcium at a record pace. When diet is insufficient and the body already starts drawing on its mineral reserves, there’s a potential that the bone density or calcium reserves in the body will never be optimal – increasing fracture risk for the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6746661/">rest of that person’s life</a>. <h2>Can bone health be fixed?</h2> Optimal bone health starts in utero, but our prepubescent years are key to <a href="https://pubmed.ncbi.nlm.nih.gov/26884506/">setting our skeleton up</a> for later life. People who are behind the curve in early life may have difficulty achieving their peak, as poor bone mineral density can affect everything from our appetite to how efficient our gastrointestinal tract is at absorbing <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6971894/">important nutrients</a> (including calcium). Supplements have a limited effect because our body can only absorb a set amount of any <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8746734/">vitamin or mineral at a time</a>. While it’s possible to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5684300/">limit some of the decline</a> in bone density that naturally happens as we age, some of the choices we make – such as not consuming enough calcium – can accelerate the decline. Biological sex also has a significant impact on our bone health in old age – with post-menopausal women at greater risk of osteoporosis because they <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5643776/">produce less oestrogen</a>, which helps keep the cells that <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3424385">degrade bone</a> in check.<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/228321/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/adam-taylor-283950">Adam Taylor</a>, Professor and Director of the Clinical Anatomy Learning Centre, <a href="https://theconversation.com/institutions/lancaster-university-1176">Lancaster University</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Dog care below freezing − how to keep your pet warm and safe from cold weather, road salt and more this winter

<a href="https://theconversation.com/profiles/erik-christian-olstad-1505284">Erik Christian Olstad</a>, <a href="https://theconversation.com/institutions/university-of-california-davis-1312">University of California, Davis</a> Time outside with your dog in the spring, summer and fall can be lovely. Visiting your favorite downtown café on a cool spring morning, going to a favorite dog park on a clear summer evening or going on walks along a river when the leaves are changing color are all wonderful when the weather is favorable. But in much of the country, when winter rolls around, previously hospitable conditions can <a href="https://theconversation.com/is-winter-miserable-for-wildlife-108734">quickly turn chilly and dangerous</a> for people and pups alike. Winter brings some unique challenges for dog owners, since dogs still need activity and socialization during colder seasons. Studies have shown that dog owners are almost 50% less likely to walk their dogs <a href="https://doi.org/10.3390/ani11113302">when the weather gets cold</a>. Knowing the basics of winter safety is critical to maintaining a healthy lifestyle for your dog. I am an <a href="https://www.vetmed.ucdavis.edu/faculty/erik-olstad">assistant professor</a> at the University of California Davis School of Veterinary Medicine who weathered polar vortexes with my dog while living in Michigan early in my career. While I’ve since moved to sunny California, I’ve seen how quickly frigid temperatures can turn dangerous for pets. <h2>Breed and age differences</h2> Not all dogs have the same abilities to deal with cold weather. A short-coated dog like a Chihuahua is much more susceptible to the dangers of cold weather than a thick-coated husky. When the weather dips below 40 degrees Fahrenheit (4 degrees Celsius), the well-acclimated husky may be comfortable, whereas the Chihuahua would shiver and be at risk of hypothermia. Additionally, if your dog is used to warm weather, but you decide to move to a colder region, the dog will need time to acclimate to that colder weather, even if they have a thick coat. Age also affects cold-weather resilience. Puppies and elderly dogs can’t withstand the chill as well as other dogs, but every dog is unique – each may have individual health conditions or physical attributes that make them more or less resilient to cold weather. <h2>When is my dog too cold?</h2> Pet owners should be able to recognize the symptoms of a dog that is getting too cold. Dogs will shiver, and some may vocalize or whine. Dogs may resist putting their feet down on the cold ground, or burrow, or try to find warmth in their environment when they are uncomfortable. Just like people, <a href="https://vcahospitals.com/know-your-pet/frostbite-in-dogs">dogs can get frostbite</a>. And just like people, the signs can take days to appear, making it hard to assess them in the moment. The most common sites for frostbite in dogs are their ears and the tips of their tails. Some of the initial signs of frostbite are skin discoloring, turning paler than normal, or purple, gray or even black; red, blistered skin; swelling; pain at the site; <a href="https://www.britannica.com/science/ulcer">or ulceration</a>. Other <a href="https://vcahospitals.com/know-your-pet/frostbite-in-dogs">serious signs of hypothermia</a> include sluggishness or lethargy, and if you observe them, please visit your veterinarian immediately. A good rule to live by is if it is too cold for you, it is too cold for your dog. Getting your dog a <a href="https://www.cnn.com/cnn-underscored/pets/best-winter-dog-coats-jackets">sweater or jacket</a> and <a href="https://www.akc.org/expert-advice/vets-corner/protect-dogs-paws-snow-ice-salt/">paw covers</a> can provide them with protection from the elements and keep them comfortable. Veterinarians also recommend closely monitoring your dog and limiting their time outside when the temperature nears the freezing point or drops below it. <h2>Road salt dangers</h2> Road salt that treats ice on streets and sidewalks <a href="https://www.cbc.ca/news/canada/kitchener-waterloo/ice-salt-toxic-for-pets-1.5020088">can also harm dogs</a>. When dogs walk on the salt, the sharp, rough edges of the salt crystals can irritate the sensitive skin on their paws. Dogs will often lick their feet when they’re dirty, wet or irritated, and if they ingest any salt doing that, they may face GI upset, dehydration, kidney failure, seizures or even death. Even small amounts of pure salt can <a href="https://www.petpoisonhelpline.com/pet-tips/my-dog-ate-road-salt-will-they-be-okay/">disrupt critical body functions</a> in dogs. Some companies make pet-safe salt, but in public it can be hard to tell what type of salt is on the ground. After walking your dog, wash off their feet or boots. You can also keep their paw fur trimmed to prevent snow from balling up or salt collecting in the fur. Applying a thin layer of petroleum jelly or <a href="https://www.akc.org/expert-advice/lifestyle/how-to-make-your-own-paw-balm-for-winter/">paw pad balm</a> to the skin of the paw pads can also help protect your pet’s paws from irritation. <h2>Antifreeze risks</h2> <a href="https://www.britannica.com/science/antifreeze-chemical-substance">Antifreeze, or ethylene glycol</a>, is in most vehicles to prevent the fluids from freezing when it gets cold out. Some people pour antifreeze into their toilets when away from their home to prevent the water in the toilet from freezing. Antifreeze is an exceptionally dangerous chemical to dogs and cats, as it tastes sweet but can be deadly when ingested. If a pet ingests even a small amount of antifreeze, the substance causes a chemical cascade in their body that results in severe kidney damage. If left untreated, the pet may have <a href="https://www.petpoisonhelpline.com/pet-owner-blog/antifreeze-poisoning/">permanent kidney damage or die</a>. There are safer antifreeze options on the market that use ingredients other than ethylene glycol. If your dog ingests antifreeze, please see your veterinarian immediately for treatment. When temperatures dip below freezing, the best thing pet owners can do is keep the time spent outside as minimal as possible. Try some <a href="https://www.akc.org/expert-advice/lifestyle/great-indoor-games-to-play-with-your-dog/">indoor activities</a>, like hide-and-seek with low-calorie treats, fetch or even an interactive obstacle course. Food puzzles can also keep your dog mentally engaged during indoor time. Although winter presents some unique challenges, it can still be an enjoyable and healthy time for you and your canine companion.<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/221709/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/erik-christian-olstad-1505284">Erik Christian Olstad</a>, Health Sciences Assistant Professor of Clinical Veterinary Medicine, <a href="https://theconversation.com/institutions/university-of-california-davis-1312">University of California, Davis</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

It’s extremely hot and I’m feeling weak and dizzy. Could I have heat stroke?

<a href="https://theconversation.com/profiles/lily-hospers-1060107">Lily Hospers</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>; <a href="https://theconversation.com/profiles/james-smallcombe-1412548">James Smallcombe</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>, and <a href="https://theconversation.com/profiles/ollie-jay-114164">Ollie Jay</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> Australia is braced for a hot, dry summer. El Nino is back, and this year it will occur alongside an <a href="https://www.abc.net.au/news/2023-08-22/positive-indian-ocean-dipole-to-coincide-with-el-nino/102756378">Indian Ocean dipole</a>, a climate pattern which will further amplify this hot and dry effect. Hot weather can place great stress on our bodies. When the environmental conditions exceed the limit at which we can adequately cope, we can suffer from heat-related illnesses. Heat illnesses can vary, from relatively mild heat exhaustion to the potentially life-threatening condition of heat stroke. <h2>What are the signs and symptoms?</h2> If you’re suffering from heat exhaustion, you may feel weakness, nausea, headaches or dizziness. Mild <a href="https://www.health.nsw.gov.au/environment/beattheheat/Pages/heat-related-illness.aspx">symptoms of heat exhaustion</a> can often be treated at home by reducing your levels of physical activity, finding shade, removing excess clothing, hydrating with water and perhaps even taking a cool shower. If left unchecked, heat exhaustion can progress to the far more serious condition of heat stroke, where your core temperature climbs upwards of 40°C. <a href="https://www.health.nsw.gov.au/environment/beattheheat/Pages/heat-related-illness.aspx">Symptoms</a> can develop rapidly and may include confusion, disorientation, agitation, convulsions, or it could even result in a coma. Heat stroke is a medical emergency and requires urgent treatment. Call an ambulance and start rapid, aggressive cooling by immersing the person in cold water (such as a cold bath). If this isn’t possible, apply ice packs to their neck, armpits and groin and cover the skin with lots of cool water. When it comes to cooling someone with suspected heat stroke, the quicker the better: cool first, transport second. <h2>Why do we overheat?</h2> Environmental conditions play an important role in determining our heat stress risk. If the air temperature, humidity and levels of sun exposure are high, we are much more likely to dangerously overheat. When the body gets hot, the heart pumps more warm blood to our skin to help lose heat. As air temperature rises, this way of shedding heat becomes ineffective. When air temperature is higher than the temperature of the skin (normally around 35°C), we start gaining heat from our surroundings. Sweating is by far our most effective physiological means of keeping cool. However, it is the evaporation of sweat from our skin that provides cooling relief. When the air is humid, it already contains a lot of moisture, and this reduces how efficiently sweat evaporates. Our physical activity levels and clothing also impact heat stress risk. When we move, our bodies generate metabolic heat as a by-product. The more intense physical activity is, the more heat we must lose to avoid dangerous rises in core temperature. Finally, clothing can act as an insulator and barrier for the evaporation of sweat, making it even more difficult for us to keep cool. <h2>Who is most vulnerable in the heat?</h2> Some people <a href="https://www.health.nsw.gov.au/environment/beattheheat/Pages/people-most-at-risk.aspx">are at greater risk</a> of developing heat illness than others. This can result from physiological limitations, such as a decreased capacity to sweat, or a reduced capacity to adapt our behaviour. When these two risk factors coincide, it’s a perfect storm of vulnerability. Take, for example, an elderly outdoor agricultural worker. Being aged over 60, their physiological capacity to sweat is reduced. The worker may also be wearing heavy safety clothing, which may further limit heat loss from the body. If they don’t slow down, seek shelter and adequately hydrate, they become even more vulnerable. When a person dies of heat stroke – which is relatively easy to diagnose – heat will be listed as a cause of death on a death certificate. Between 2001 and 2018 in Australia, 473 heat-related deaths were <a href="https://www.sciencedirect.com/science/article/pii/S2212420921006324">officially reported</a>. However, the true association between heat and death is thought to be far greater, with an <a href="https://www.thelancet.com/journals/lanplh/article/PIIS2542-5196(20)30100-5/fulltext">estimated 36,000 deaths</a> in Australia between 2006 and 2017. This is because most people who die during extreme heat events do not die from heat stroke. Instead, they they die of <a href="https://www.nejm.org/doi/full/10.1056/nejm199607113350203">other medical complications</a> such as cardiovascular or renal collapse, as additional strain is placed on essential organs such as the heart and kidneys. People with underlying health conditions are more likely to succumb to heat-associated complications before they develop critical core temperature (over 40°C) and heat stroke. In such cases, while the additional physiological strain imposed by the heat probably “caused” the death, the official “cause of death” is often listed as something else, such as a heart attack. This can make understanding the true health burden of extreme heat more difficult. <h2>How to stay safe in the heat</h2> Thankfully, there are effective, low-cost <a href="https://twitter.com/TheLancet/status/1677702906789740545">ways</a> of staying safe in the heat.

4 ways to support someone with dementia during extreme heat

<a href="https://theconversation.com/profiles/nikki-anne-wilson-342631">Nikki-Anne Wilson</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> Our ability to adapt our behaviour to changes in temperature takes a significant amount of thought and decision making. For example, we need to identify suitable clothing, increase our fluid intake, and understand how to best keep the house cool. A person with dementia may find some or all these things challenging. These and other factors mean, for someone with dementia, extreme heat <a href="https://pubmed.ncbi.nlm.nih.gov/31520832/#:%7E:text=Conclusion%3A%20Heatwaves%20increased%20the%20risk,heat%2Drelated%20Alzheimer's%20disease%20burden.">can be deadly</a>. But as the temperature rises, friends, relatives and carers can help. <h2>El Niño means there are challenges ahead</h2> The recent declaration of <a href="https://www.abc.net.au/news/2023-09-19/bureau-of-meteorology-el-nino-blog/102875154">another El Niño</a> means we need to think about how we can best support those more vulnerable to be safe during the warmer months. Extreme heat and bushfires bring unique challenges for someone with dementia. Bushfires have a significant impact on older people’s mental health. But they generally <a href="https://www.health.act.gov.au/sites/default/files/2023-03/PATH_Impact%20of%202019-20%20Bushfires%20on%20a%20Cohort%20of%20Older%20Adults_REPORT_V3_0.pdf">bounce back</a> quickly. However, for someone with dementia, extreme heat can lead to a <a href="https://www.sciencedirect.com/science/article/pii/S0013935119305110">significant deterioration</a> in their overall health and they may not recover. Emergency evacuations can also be confusing and distressing for a person with dementia, so it is important to think ahead. <h2>Why are people with dementia more at risk?</h2> Dementia can affect the parts of the brain that help <a href="https://academic.oup.com/brain/article/138/11/3360/332653?login=true">regulate</a> our body temperature. Some <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0243665">medications</a> can also increase someone’s sensitivity to heat. Problems with memory and thinking associated with dementia <a href="https://www.alzheimers.org.uk/get-support/daily-living/drinking-hydration">means</a> remembering to drink or communicating you are thirsty can be challenging. Heat can affect everyone’s mood. But if someone with dementia becomes dehydrated this can <a href="https://www.alzdiscovery.org/cognitive-vitality/blog/can-dehydration-impair-cognitive-function">increase</a> confusion and agitation, making it harder for them to know how to cool down. A person with dementia can also wander and become lost, which can be dangerous in extreme heat. <h2>4 ways to support someone with dementia</h2> 1. Avoid dehydration and heatstroke Try to avoid dehydration by encouraging someone to drink throughout the day. It’s better to have <a href="https://pubmed.ncbi.nlm.nih.gov/31769256/">small amounts</a> of liquid regularly instead of a large amount all at once. Little and often will help maximise hydration while avoiding sudden trips to <a href="https://www.betterhealth.vic.gov.au/health/conditionsandtreatments/dementia-continence-issues#causes-of-incontinence-in-people-with-dementia">the bathroom</a>. Try to offer different types of drinks, or ice blocks. Placing drinks in sight can help as a reminder to drink. Choose foods with a high liquid content, such as fruit, salads, cool broths and yoghurt. Look out for <a href="https://www.nia.nih.gov/health/hot-weather-safety-older-adults#:%7E:text=Signs%20of%20heat%20stroke%20are,as%20under%20shade%20or%20indoors.">signs of heatstroke</a>, such as increased confusion beyond what the person would usually experience. Heatstroke may be more difficult to spot in someone living with dementia so it is important to check in when possible and to help them cool down if needed. 2. Cool the home Try to modify their home to make it easier to stay cool. Some air-conditioners have complex settings so make sure the temperature is set appropriately and the person with dementia knows how to use the controls. It is important to keep blinds and curtains shut where possible to reduce heat. However, ensure the <a href="https://www.scie.org.uk/dementia/supporting-people-with-dementia/dementia-friendly-environments/lighting.asp">lighting is adequate</a> to avoid falls. Try to support the person to make suitable clothing choices for the season by having cool, lightweight options easily available. 3. Think about communications early If someone with dementia lives alone, consider how you will maintain contact in an emergency. Some people may not realise many landlines don’t work in a power outage, and of course, mobile phones can’t be recharged. Ensure the person with dementia has access to an <a href="https://www.telstra.com.au/support/category/home-phone/uninterruptible-power-supply">uninterruptable power supply</a>. This can help maintain communication for a few hours in a blackout. 4. Have an evacuation plan In case of fire, flash flooding or severe storm, <a href="https://dementiaresearch.org.au/wp-content/uploads/2017/10/2447_DCRC_Prep_natural_disaster_EBook_5.pdf">have an evacuation plan</a>. If the person with dementia attends a day or respite centre, know their plan too. The situation can change quickly in an emergency, and this can be particularly overwhelming for people with cognitive issues. Understand that someone with dementia may become distressed when their routine is disrupted. So be prepared with some simple activities or comfort items, current medications, and any specific medical information. Stay up-to-date with <a href="http://www.bom.gov.au/">current warnings</a> and act early whenever possible. <h2>We can all help</h2> It’s not just carers of people with dementia who can help. We can all ensure people with dementia stay safe and cool this spring and summer. So remember to check in on your relatives, friends and neighbours or arrange for someone to do so on your behalf.<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/213987/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/nikki-anne-wilson-342631">Nikki-Anne Wilson</a>, Postdoctoral Research Fellow, Neuroscience Research Australia (NeuRA), <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

It’s warming up and mozzies are coming. Here’s how to mosquito-proof your backyard

<a href="https://theconversation.com/profiles/cameron-webb-6736">Cameron Webb</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> The weather is warming up and that means more time in the backyard. It also means more mosquitoes. Here are five ways you can mosquito-proof your backyard that <a href="https://theconversation.com/the-battle-against-bugs-its-time-to-end-chemical-warfare-111629">don’t rely on spraying insecticides</a>. <h2>1. Get rid of water</h2> Mosquitoes need water to complete their life cycles. They <a href="https://theconversation.com/feel-like-youre-a-mozzie-magnet-its-true-mosquitoes-prefer-to-bite-some-people-over-others-128788">need blood</a> – but water and warmth are just as important. Getting rid of water around your backyard will go a long way to keeping mosquitoes away. Water trapped in blocked roof gutters, drains and tarpaulin covering boats and trailers can be a great home for mosquitoes. Mosquitoes can exploit the tiniest of water sources too. It may just be the upturned lid of a discarded plastic drink bottle. If it traps water, mosquitoes will find it and lay eggs in it. Flush out your bird bath once a week to disrupt the mosquito’s life cycle. If you have a pond, installing a fountain will discourage mosquitoes. If you can’t keep water clean and circulating, consider filling it with sand and gravel to create an interesting garden bed for succulents or other plants. Mosquitoes will avoid clean and chlorinated swimming pools but will quickly move into “green pools”. If you’re not using your pool, consider <a href="https://www.krg.nsw.gov.au/Environment/Your-local-environment/Wildlife/Living-with-wildlife/Pool-to-pond/How-to-convert-your-pool">converting it to a “pond”</a> so that fish can help keep mosquito numbers down. <h2>2. Screen up – windows, doors and rainwater tanks</h2> If you can’t get rid of permanent water, at least stop mosquitoes getting to it (or you). Ensure <a href="https://www.brisbane.qld.gov.au/clean-and-green/natural-environment-and-water/water/water-smart-homes/rainwater-tanks/using-your-rainwater-tank">rainwater and septic tanks</a> have screens to stop mosquitoes entering. Screen windows and doors to stop mosquitoes entering the home. There are plenty of flexible screening options for windows, doors and balconies. If you live in a mosquito-prone area, creating a screened outdoor area (such as a pergola, courtyard, or balcony) will give you the opportunity to spend time outdoors without being hassled by mozzies. <h2>3. Choose your garden plants carefully</h2> Some plants <a href="https://bioone.org/journals/Journal-of-the-American-Mosquito-Control-Association/volume-25/issue-3/09-0016.1/Are-Commercially-Available-Essential-Oils-from-Australian-Native-Plants-Repellent/10.2987/09-0016.1.short">contain essential oils and other chemicals</a> that, when extracted and concentrated, provide protection against biting mosquitoes. But there isn’t a lot of evidence that the whole plant will keep mosquitoes away from your garden. Some types of plants are even marketed as “mozzie blockers” or “mosquito repelling”. But there isn’t <a href="https://www.veranda.com/outdoor-garden/a40592197/do-mosquito-repelling-plants-work/">any evidence of effectiveness</a>. In fact, some of these plants, <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/j.1440-6055.2009.00736.x">such as melaleucas</a>, also happen to be associated with <a href="https://academic.oup.com/jme/article/36/4/515/903838">hot spots of mosquito breeding</a> in coastal Australia. The plants to avoid around the home are those that help mosquitoes breed, such as <a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/j.1440-6055.2008.00641.x">bromeliads</a>, which trap water. <h2>4. Encourage the animals that eat mosquitoes</h2> Mosquitoes are food for a range of animals including birds, bats, fish, frogs, lizards, insects, spiders and <a href="https://besjournals.onlinelibrary.wiley.com/doi/abs/10.1111/1365-2656.13965">dragonflies</a>. But don’t expect them to eat enough to keep all mosquitoes away. Bats are often promoted as a good “biological control” options but studies have shown mosquitoes are <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0077183">more likely to be a snack food</a> for small bats, not an irresistible staple of their diet. For garden ponds, frogs will eat a few adult mosquitoes but tadpoles of Australian frogs generally <a href="https://bioone.org/journals/journal-of-the-american-mosquito-control-association/volume-21/issue-4/8756-971X(2006)21%5b492%3aTOFCAF%5d2.0.CO%3b2/TADPOLES-OF-FOUR-COMMON-AUSTRALIAN-FROGS-ARE-NOT-EFFECTIVE-PREDATORS/10.2987/8756-971X(2006)21%5B492:TOFCAF%5D2.0.CO;2.short">don’t eat many mosquito “wrigglers”</a>. Australian native fish <a href="https://pubmed.ncbi.nlm.nih.gov/15532929/">will readily eat mosquitoes</a> and may be useful for backyard ponds. But not all fish are good. While “mosquitofish” (aka “plague minnow”) is distributed overseas to assist in mosquito control, <a href="https://meridian.allenpress.com/australian-zoologist/article/30/3/316/134508/Does-predation-by-the-fish-Gambusia-holbrooki">it’s a disaster for local wildlife</a> and, <a href="https://www.dpi.nsw.gov.au/fishing/aquatic-biosecurity/pests-diseases/freshwater-pests/finfish-species/gambusia">along with other exotic fish species</a>, should not be released into local waterways. <a href="https://link.springer.com/article/10.1007/s13157-019-01133-2">Healthier habitats promote fewer mosquitoes</a> so the best thing you can do is create habitats for the animals that eat mosquitoes. <h2>5. Avoid traps and other gadgets</h2> There are lots of devices purported to catch, kill, or repel mosquitoes from your garden. Some may catch a mosquito or two but they’re not very effective in knocking out big numbers. “Bug zappers” with bright lights will collect lots of flying insects. It’s just that mosquitoes make up a very small proportion of collections. Electrocuting devices, again, don’t seem to attract a lot of mosquitoes. Devices that <a href="https://theconversation.com/the-buzz-from-your-smartphone-wont-stop-mosquito-bites-92611">emit high frequency sounds</a> won’t help either. The best devices are typically those that are baited with carbon dioxide. These are a mainstay of state and territory <a href="https://www.health.nsw.gov.au/Infectious/mosquito-borne/Pages/surveillance.aspx">mosquito and arbovirus surveillance programs</a>. For a mosquito, the C0₂ tricks them into thinking the trap is a warm-blooded animal. The only problem is these can be expensive to run and don’t seem quite as effective for mosquito control <a href="https://bioone.org/journals/journal-of-the-american-mosquito-control-association/volume-22/issue-3/8756-971X(2006)22%5b490%3aTATTFA%5d2.0.CO%3b2/Traps-and-Trapping-Techniques-for-Adult-Mosquito-Control/10.2987/8756-971X(2006)22%5B490:TATTFA%5D2.0.CO;2.short">unless used in large numbers</a>. <h2>Yes, you’ll still need repellent</h2> Perhaps the best way to avoid mosquito bites is to pick an insect repellent <a href="https://www.phrp.com.au/issues/december-2016-volume-26-issue-5/a-review-of-recommendations-on-the-safe-and-effective-use-of-topical-mosquito-repellents/">recommended by health authorities</a> and <a href="https://theconversation.com/mozzies-biting-heres-how-to-choose-a-repellent-and-how-to-use-it-for-the-best-protection-150183">apply it</a> to ensure all exposed areas of skin are covered. These products and safe, affordable and effective.<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/212711/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/cameron-webb-6736">Cameron Webb</a>, Clinical Associate Professor and Principal Hospital Scientist, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

10 driving tips to stay safe in wet weather

Driving in the rain? Follow these tips for safe driving in wet weather This should go without saying, but reducing your speed – as long as you continue to keep with the flow of traffic, of course – is imperative when driving in the rain. After all, between the downpour and spray from other vehicles, heavy rain reduces visibility in all directions, and you need more time to react. Keep your distance Driving in the rain can be hazardous, and if ever there is an incident that requires you – or the driver in front you – to brake unexpectedly, you’ll want to have ample stopping distance on wet roads. Avoid heavy breaking While driving in the rain, you may find yourself in situations – whether you’re hydroplaning or finding yourself in a skid – that will tempt you to hit the brakes abruptly. Do your best to curb that impulse. Brakes can be affected greatly by water, losing a bit of their power when wet, which can be disastrous in an emergency. Easing off the brakes, slowing down and maintaining control of your vehicle is your best bet. Keep both hands on the wheel Control is of utmost importance when driving in the rain. After all, you need to be in command of your vehicle should an incident occur, and having both hands on the wheel while driving in the rain (no snacking or fiddling with the radio!) will ensure you can get out of a sticky situation quickly and efficiently. Keep windows from fogging up When driving in rain, windows tend to fog up as a result of the difference in temperatures inside and outside the car and can lead to decreased visibility. To stay safe and avoid accidents, simply press your car’s defrost button to clear-up the window. Turn on your A/C or roll down the windows by a couple of centimetres to remove the humidity from the vehicle and lower the temperature inside the car. If the issue persists, you may want to purchase a windshield cleaner and defogger. Beware of hydroplaning Hydroplaning happens when your car travels above the water without touching the ground. Given that a driver is left with little-to-no grip with the road and, thus, less control, this can be a dangerous set of circumstances. If you find yourself in such a situation, stay calm, ease off the brakes and do not turn your steering wheel; let your car slow down and the tires reattach to the road surface. Avoid puddles Windshield wipers should always be in working condition. Be vigilant about replacing them once per year, or whenever they start to leave streaks on the glass. Having wipers blades in tip-top shape ensures the best possible visibility when driving in the rain. Stay home if you can If you have no choice but to head outside during a heavy downpour, be sure to follow these driving tips. However, if you don’t have anywhere pressing to be, consider staying home and waiting it out until the storm subsides. Keep your headlights on With wet weather often comes fog and overall gloominess. With your surroundings slightly darkened, turning on your headlights ensures that you can see the road in front of you, and that other drivers can see you. Ensure windshield wipers are in working order Windshield wipers should always be in working condition. Be vigilant about replacing them once per year, or whenever they start to leave streaks on the glass. Having wipers blades in tip-top shape ensures the best possible visibility when driving in the rain.

How climate change will affect your pet – and how to help them cope

<a href="https://theconversation.com/profiles/edward-narayan-414899">Edward Narayan</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> Earth has just experienced its <a href="https://www.theguardian.com/science/2023/jul/27/scientists-july-world-hottest-month-record-climate-temperatures">hottest month</a> since records began and Australia is now gearing up for an El Niño-fuelled summer. Extreme heat isn’t just challenging for humans – it brings suffering to our beloved pets, too. <a href="https://www.cabidigitallibrary.org/doi/10.1079/cabireviews.2023.0020">Research</a> I was involved in examined how climate change affects the welfare of animals, including pets. My colleagues and I used a concept for assessing animal welfare known as the “<a href="https://kb.rspca.org.au/knowledge-base/what-are-the-five-domains-and-how-do-they-differ-from-the-five-freedoms/">five-domains model</a>”. It’s a science-based structure for examining an animal’s: <ul> <li>nutrition</li> <li>environment</li> <li>physical health</li> <li>behaviour</li> <li>mental state.</li> </ul> The model evaluates the complete physiological and behavioural responses of animals to environmental stressors. While the effects of climate change on animals have been studied before, ours is the first study to apply the model to animal welfare specifically. We examined the academic literature and found climate change will harm animals across all five welfare domains. This applies to both wild and domesticated animals, including pets. So let’s take a look at how various types of pets will fare in a warming world – and how we can help them. <h2>Fish</h2> Fish are “ectotherms” – that is, they use external sources of heat to regulate their body temperature. So pet fish are vulnerable to changes in the water temperature of your home aquarium, which may occur during a heatwave. Extreme water temperatures can cause physical harm to fish. For example, it can increase a fish’s metabolic rate – meaning it <a href="https://e360.yale.edu/features/feeling-the-heat-warming-oceans-drive-fish-into-cooler-waters">needs more oxygen</a> to breathe . It can also <a href="https://www.nepjol.info/index.php/ON/article/view/4331">cause changes</a> such as slowed growth and reduced feeding. According to <a href="https://agriculture.vic.gov.au/livestock-and-animals/animal-welfare-victoria/other-pets/caring-for-your-pet-fish">official advice</a>, water in an indoor aquarium should generally be kept at between 20℃ and 25℃ (unless you are keeping tropical fish). Depending on your budget and aquarium size, you could opt to use a device to control the water temperature. Either way, it’s important to monitor the water temperature regularly. Also make sure the aquarium isn’t located near a window where it’s exposed to direct sunlight. Leaving your aquarium unattended for days or weeks in summer can be dangerous, due to the risk of heatwaves. If you’re going on a summer holiday, consider organising a <a href="https://www.thesprucepets.com/holiday-and-vacation-fish-care-and-feeding-1378525#:%7E:text=If%20you%20are%20going%20on,aquarium%20and%20can%20prove%20lethal">fish sitter</a> to check on the animal regularly. <h2>Birds</h2> Heat stress can change the <a href="https://www.vetexotic.theclinics.com/article/S1094-9194(16)00003-7/fulltext">physiology</a> of birds. For example, research into a wild population of small Australian robins showed during a heatwave, the birds <a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/jav.02355">lost body mass</a> and abandoned their nests, and some died. Heat stress can also cause <a href="https://www.tandfonline.com/doi/abs/10.1207/s15327604jaws0101_5">abnormal behaviour in pet birds</a> such as <a href="https://www.tandfonline.com/doi/full/10.1080/1828051X.2016.1195711?src=recsys">feather picking</a>, when one bird repeatedly pecks at the feathers of another. In hot weather, regularly check your bird’s cage to make sure it’s clean and stocked with food and water. If the bird is in an outdoor cage or aviary, ensure it is shaded. And a shallow bird bath will help your feathered friend cool off. <h2>Dogs</h2> Dogs and cats can suffer on hot days. That’s especially true if they are: <ul> <li><a href="https://www.ejmanager.com/mnstemps/100/100-1626960667.pdf?t=1657722662">older or overweight</a></li> <li>have thick coats</li> <li>have short snouts/flat faces (which restricts air flow and makes it harder for them to cool down).</li> </ul> Heat stress can cause <a href="https://www.frontiersin.org/articles/10.3389/fvets.2021.742926/full?&utm_source=Email_to_ae_&utm_medium=Email&utm_content=T1_11.5e2_editor&utm_campaign=Email_publication&journalName=Frontiers_in_Veterinary_Science&id=742926">canine hyperthermia</a>, which means the dog’s body temperature becomes dangerously hot. Watch for <a href="https://www.rvc.ac.uk/small-animal-vet/teaching-and-research/fact-files/heatstroke-in-dogs-and-cats#:%7E:text=Early%20signs%20of%20heatstroke%20in%20pet%20animals&text=Panting%2C%20this%20can%20progress%20to,Red%20gums%20or%20tongue">early warning signs</a> of heat stress such as excessive panting and erratic movements. These symptoms can quickly escalate, leading to heat stroke and possible death. <a href="https://pubmed.ncbi.nlm.nih.gov/34828033/">More than 80%</a> of dog owners report exercising their dogs less vigorously, or for shorter periods, during hot weather. That can help avoid heat-related illness. But don’t reduce your dog’s activity levels too much, as that may lead to other health problems. Just time the walks to avoid the heat of the day. Refrain from leaving dogs unattended in vehicles, because they can easily overheat. In fact, it’s better to leave your dog inside home on a hot day, as long as they have a cool place to rest and plenty of water – perhaps even with ice cubes in it. And dogs love to cool off in a kiddie pool or under a sprinkler. If you take your dog out on a hot day, <a href="https://agriculture.vic.gov.au/livestock-and-animals/animal-welfare-victoria/dogs/health/heat-and-pets#:%7E:text=Be%20aware%20of%20the%20signs,not%20icy%20water%20and%20fanned">carry</a> a container of fresh, cool water for them. And don’t forget to slip-slop-slap: apply a sparing amount of pet sunscreen to your dogs’ exposed pink skin such as ear tips and nose. <h2>Cats</h2> Like other animals, cats can overheat in hot weather. Symptoms include panting heavily, drooling and a rapid pulse. Like with other animals, if you suspect your cat is suffering from heatstroke, call a vet immediately. Climate change and associated heat and floods is likely to aid the spread of parasites and illness <a href="https://www.forbes.com/sites/jeffmcmahon/2022/12/31/guess-whos-loving-climate-change-mosquitos-and-the-pathogens-they-carry/?sh=50654683174a">including</a> tick-borne diseases, <a href="https://pubs.er.usgs.gov/publication/70213352">flea</a> infestations and <a href="https://pubmed.ncbi.nlm.nih.gov/32145530/">heartworm</a>. This puts both cats and dogs at risk. In hot weather, the advice for cat owners is similar to that of dog owners: ensure your cat has plenty of shade and water, and put pet sunscreen on their ear tips and noses, especially if the cat is white. If possible, keep the cat inside during the hottest part of the day. Ensure at least one room is cool and ventilated. And in a heatwave, play with your cat either in the early morning or evening, when the temperature has cooled. <h2>A helping human hand</h2> While humans have the capacity to understand and prepare for climate change, pets will need our help to cope. This includes not just the pets listed above, but others too, including reptiles, guinea pigs and rabbits. As heatwaves and other extreme weather events become more common, the onus is on us to keep our pets safe.<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/210724/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/edward-narayan-414899">Edward Narayan</a>, Senior Lecturer in Animal Science, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

"I can’t a fjord it": Inside one of the world’s most extreme restaurants

One of the world's most extreme restaurants has gone viral and not only for its unique location and shape, but also its exclusive dining experience that's eerily similar to 2022 horror film The Menu. Restaurant Iris is located inside a giant silvery orb in Hardangerfjord, the second largest Fjord in Norway. The four-storey structure, called the Salmon Eye is inspired by - you guessed it - the shape of a fish eye, and it is quite a sight to behold. The Salmon Eye is covered in 9,000 steel plates to emulate fish scales, weighing a whopping 1,256 tonnes and an impressive diameter of 25 metres, with one sub-surface floor that boasts a panoramic view of the Fjord. The restaurant itself can only be accessed by an electric boat off the shore of Rosendal, as guests are treated to "an exclusive expedition dining-journey" which offers an 18-course meal and panoramic views. The 24-seat restaurant is run by Head Chef Anika Madsen, and prior to having their main meal, guests are taken to the chef's boathouse on the nearby island of Snilstveitoy, for a "welcoming snack". The menu is designed to showcase "the most local ingredients possible", which reflects Madsen's "commitment to sustainability" and her "passion for discovering new ingredients from the ocean". Mari Eriksmoen posted the viral video on TikTok which has racked up over eight million views. "This spectacular just opened in the middle of the Hardangerfjord in Norway," she started in the clip with a shot of the structure floating in the middle of the fjord. She described the experience of walking into the restaurant "like entering a spaceship," and was mesmerised by the "insane views". Once the evening kicks off, guests indulge in a multi-sensory experience where they were instructed to pick a "cracker" hanging from the ceiling after watching a "short movie about food waste". Another TikTok user compared it to the extraterrestrial spacecraft from the 2016 sci-fi film Arrival. However many other users compared the dining experience to 2022 horror film The Menu, where a group of guests eat at an exclusive restaurant on a remote island and face dire consequences. "Did we learn nothing from The Menu?" commented one user with the crying face emoji. "I know how this movie ends," wrote another user. "I can’t a fjord it," joked a third. The dining experience aims to "blend gastronomy and activism on a global scale" as they hope to raise awareness on the the challenges and threats to the global food system. "The menu at Iris reads like a story, " a statement said. "A story about the challenges and threats to the global food system, but also with ideas and suggestions for future innovations, that can help bring us closer to solving them." The tasting menu itself is priced at 3,200 Norwegian Krone ($316) with an optional wine pairing for 2,500 Norwegian Krone ($247). For those who want to visit the Salmon Eye, but don't want to dine in, they can buy a ticket for a two-hour "learning experience" at the centre priced at 349 Norwegian Krone ($34).

Extreme weather events are exactly the time to talk about climate change – here’s why

<a href="https://theconversation.com/profiles/josh-ettinger-1302389">Josh Ettinger</a>, <a href="https://theconversation.com/institutions/university-of-oxford-1260">University of Oxford</a> Record-breaking heatwaves are <a href="https://public.wmo.int/en/media/news/simultaneous-heatwaves-hit-northern-hemisphere-summer-of-extremes">sweeping across the northern hemisphere</a>, affecting large parts of southern Europe, the US and China. On July 24, Sicily recorded blistering temperatures <a href="https://www.bbc.com/news/world-europe-66302472">of more than 47.5℃</a> and wildfires are currently <a href="https://www.theguardian.com/world/2023/jul/25/how-bad-are-wildfires-in-greece-what-caused-them-visual-guide-heatwave">tearing through Greece</a>. The heatwaves come as <a href="https://www.reuters.com/graphics/CANADA-WILDFIRE/HISTORIC/znvnzebmavl/">record numbers of fires continue to burn</a> across Canada. A <a href="https://www.bbc.co.uk/news/science-environment-66289489">study by the World Weather Attribution group</a> found that these heatwaves would have been “virtually impossible” without climate change. In fact, the heatwave that is affecting parts of China was made 50 times more likely by global warming. This is exactly what climate scientists have been warning us about for decades – climate change makes many types of extreme weather event <a href="https://www.carbonbrief.org/explainer-what-the-new-ipcc-report-says-about-extreme-weather-and-climate-change/">more likely, more intense and longer lasting</a>. As a PhD researcher examining extreme weather events and climate change communication, I have spent the past four years exploring how extreme weather events may affect the way the public feels, thinks and acts on climate change. One area of interest to researchers is how extreme weather events might reduce the <a href="https://www.sciencedirect.com/science/article/pii/S0272494422000676">“psychological distance”</a> associated with climate change. While climate change can feel abstract and vague, extreme weather is something people can experience firsthand. But <a href="https://iopscience.iop.org/article/10.1088/1748-9326/ab466a/meta">research offers contrasting results</a>. Some studies have found that extreme weather events lead to an <a href="https://www.journals.uchicago.edu/doi/full/10.1017/S0022381612000448?casa_token=dTns6Kvds1AAAAAA%3AkQcleVJ95vJUyh5Pg2vxvFEDbzfR1RsuOI131QCMO0wvdtIiLSVEq4EW6fZYwC7Yhraxj-NB9g">increased belief</a> that human-driven climate change is occurring and <a href="https://link.springer.com/article/10.1007/s10584-016-1837-4">greater support for climate action</a>. Others <a href="https://link.springer.com/article/10.1007/s10584-021-03176-z">find no effects</a> or suggest that these effects are <a href="https://www.sciencedirect.com/science/article/abs/pii/S0959378017309135?via%3Dihub">only temporary</a>. However, <a href="https://www.nature.com/articles/s41467-022-32412-y">we often underestimate</a> how much the public already cares about climate change. In Britain, <a href="https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/1164127/desnz-pat-spring-2023-net-zero-and-climate-change.pdf">just 4% of the public</a> say they are not at all concerned about climate change, while only <a href="https://climatecommunication.yale.edu/about/projects/global-warmings-six-americas/">11% of Americans</a> dismiss the issue. Given that <a href="https://www.pewresearch.org/short-reads/2019/04/18/a-look-at-how-people-around-the-world-view-climate-change/">most people</a> are already concerned about climate change, an important question now is how to shift these existing concerns into action. <a href="https://theconversation.com/how-to-talk-to-your-family-and-friends-about-the-new-ipcc-report-five-tips-from-climate-change-communication-research-202306">Talking about climate change</a> is a powerful way of mobilising climate action, and extreme weather events provide helpful climate conversation starters. We can use these moments as opportunities to <a href="https://journals.sagepub.com/doi/10.1177/20563051231177930">engage our families, friends and communities</a> in discussions about how climate change may relate to these events and <a href="https://drawdown.org/solutions">what we can do about it</a>. So, if you decide to engage people you know in discussions about extreme weather and climate change, here are a few thoughts and guidelines to keep in mind. <h2>1. Listen and share perspectives</h2> <a href="https://www.sciencedirect.com/science/article/abs/pii/S0887618520300773">Extreme weather events can be traumatic</a> and climate change can evoke a wide range of emotional responses. If the person you are talking to is comfortable discussing the topic, ask them about their experiences and observations. Encourage them to tell stories and affirm the validity of their emotional response – whether they are afraid, angry, hopeful or worried. There is no one right way to feel about climate change, so listen to what they have to say and then share your own perspective too. <h2>2. Talk about planning and preparation</h2> When discussing extreme weather events, some people may link their experiences to climate change, while others focus on various local factors that contribute to extreme weather risks. The risks associated with extreme weather arise from a <a href="https://www.ipcc.ch/report/ar6/wg2/chapter/summary-for-policymakers/">combination</a> of factors. These include the weather itself, which can be influenced by climate change, the level of exposure of people and places to extreme weather and the vulnerability of those to harm. Climate change, for instance, can affect the frequency, intensity and duration of wildfires. But emergency responses, evacuation procedures, firefighting and healthcare systems are crucially important to reduce risks. There are also significant equity and justice implications of extreme weather as different populations are <a href="https://link.springer.com/article/10.1007/s41885-020-00060-5">affected disproportionally</a>. It’s also important to bear in mind that while climate change affects many extreme weather events, it <a href="https://www.carbonbrief.org/climate-change-not-the-main-driver-of-madagascar-food-crisis-scientists-find/">does not necessarily affect every instance</a>. Weather systems are complex and there are <a href="https://theconversation.com/heres-why-climate-change-isnt-always-to-blame-for-extreme-rainfall-206958">meteorological processes</a> that scientists are still trying to understand. We also need to make sure the roles of local planning and preparation in minimising the impact of these events are not overlooked. <h2>3. Challenge arguments about politicising the weather</h2> In May 2023, Republican governor of Florida, Ron DeSantis, dismissed concerns about global warming by claiming that he rejects the <a href="https://www.independent.co.uk/news/world/americas/us-politics/desantis-climate-change-fox-news-b2346211.html">“politicisation of the weather”</a>. Ontario premier, Doug Ford, recently <a href="https://www.cbc.ca/news/canada/toronto/ontario-climate-change-forest-fires-politics-ford-stiles-1.6869071">made a similar argument</a> about Canada’s wildfires. In conversations, it’s possible that someone might accuse you too of “politicising” the weather. You can (respectfully) push back against this claim. This argument is a <a href="https://www.cambridge.org/core/journals/global-sustainability/article/discourses-of-climate-delay/7B11B722E3E3454BB6212378E32985A7">discourse of climate delay</a>. Rather than denying the existence of human-driven climate change, climate delay discourses try to shut down climate discussions and cast doubt on the need to act very quickly. These arguments disingenuously assert that acting on climate is too expensive, too late or that someone else should take care of it – and they are <a href="https://theconversation.com/climate-change-multi-country-media-analysis-shows-scepticism-of-the-basic-science-is-dying-out-198303">becoming increasingly common</a>. If we shouldn’t discuss climate change when extreme weather occurs, then when is the right time? If we want to protect lives, we need to talk about – and act upon – the risks associated with extreme weather events and the disasters they can cause. If talking about climate change politicises the weather, so be it. The politics of climate denial and delay affected this summer’s weather, and our current decisions will shape our planet for thousands of years. The science is clear. Act now or face increasingly dire consequences.<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/210412/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/josh-ettinger-1302389">Josh Ettinger</a>, Doctoral researcher, School of Geography and the Environment, <a href="https://theconversation.com/institutions/university-of-oxford-1260">University of Oxford</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Travel Trouble

Extreme Hollywood body transformations have become standard preparations for film actors – but we need to consider the consequences

<a href="https://theconversation.com/profiles/gemma-sharp-314703">Gemma Sharp</a>, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> and <a href="https://theconversation.com/profiles/bronwyn-dwyer-1453560">Bronwyn Dwyer</a>, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> “…when you’re shooting a film like Magic Mike, and you’re doing dance routines for two weeks at a time, you have to peak every day. So that became kind of crazy. We had a gym in the parking lot, and we’d all be lifting weights on set all day,” <a href="https://wegotthiscovered.com/movies/interview-channing-tatum-joe-manganiello-magic-mike/">explained actor Joe Manganiello</a>, about performing in the film Magic Mike. It is not unusual for actors to undergo drastic changes in preparation for a role, including gaining muscle and losing body fat for that shredded look. In fact, this is becoming the norm in Hollywood. <a href="https://www.menshealth.com/fitness/a43945188/jake-gyllenhaals-road-house-transformation/">Jake Gyllenhaal</a> in Road House, <a href="https://www.insider.com/michelle-rodriguez-rege-jean-page-workout-dungeons-and-dragons-sdcc-2022-7">Michelle Rodriguez</a> in Dungeons & Dragons, and <a href="https://www.menshealth.com/entertainment/a42532547/paul-rudd-marvel-ant-man-interview/">Paul Rudd</a> in Ant-Man and the Wasp: Quantumania, have all undertaken body modifications for roles this year. As the audience, we readily accept these body modifications to be part of the preparation for the role without necessarily considering the potentially long-term physical and mental health consequences. <h2>So how do they do it?</h2> From what Hollywood shares with the general public about these body modifications, which is generally very limited, it appears these transformations occur through excessive exercise and highly restrictive diets. Nevertheless, these Hollywood workouts are highly popular with ordinary people, with Dwayne “The Rock” Johnson and Chris Hemsworth’s workouts <a href="https://sustainhealth.fit/lifestyle/most-searched-hollywood-actor-workouts/">particularly sought after</a>. These regimens resemble those of competitive bodybuilders, <a href="https://journals.lww.com/hrpjournal/Abstract/2019/07000/Competitive_Bodybuilding__Fitness,_Pathology,_or.3.aspx">whose success also relies on appearance</a>. The <a href="https://link.springer.com/article/10.2165/00007256-200434050-00004">typical process for bodybuilders</a> involves two phases: a “bulking” phase, during which the goal is to have enough energy for muscle growth, and a “cutting” phase, when the aim is to lose weight but not muscle. The end result of such a process is usually highly applauded, even though drastic measures have been taken to achieve such a look. Actors of all genders are undergoing these body transformations for <a href="https://www.sportskeeda.com/comics/10-marvel-actors-whose-body-transformation-shocked-world">various roles</a> such as superheroes, athletes, or the portrayal of real-life people. <h2>What are the consequences?</h2> “I’ve become a little bit more boring now, because I’m older and I feel like if I keep doing what I’ve done in the past I’m going to die. So, I’d prefer not to die,” <a href="https://www.menshealth.com/uk/fitness/lifestyle/a29725245/christian-bale-no-more-body-transformation-roles/">said Christian Bale</a>, who has undertaken multiple extreme transformations for roles. To achieve what is needed for a particular role, extreme measures are often taken. However, the consequences of these measures, such as use of substances, exercise dependence, and an increased risk of developing muscle dysmorphia and/or an eating disorder, is seemingly not common knowledge. A concern for the bodybuilding community is the widespread use of drugs, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4026349/">often multiple drugs at a time not obtained through prescription</a>. Androgenic-anabolic steroids are commonly used which can have extensive negative effects on the human body, including on the cardiovascular system, hormones, metabolism and even psychiatric wellbeing. Exercise dependence can also occur when an individual engages in an extreme amount of exercise, to the point at which <a href="https://link.springer.com/article/10.1007/s11936-018-0674-3">physical, psychological or emotional harm</a> can occur. We are not sure exactly why exercise dependence happens, but it could potentially be a form of <a href="https://www.tandfonline.com/doi/full/10.1080/19585969.2023.2164841">behavioural addiction</a>. Another risk is <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4977020/">muscle dysmorphia</a>, a subtype of body dysmorphic disorder characterised by the individual being preoccupied with the idea their physique is not muscular enough, even if they have a high degree of muscle. <h2>What about the dieting impacts?</h2> There are many similarities between the requirements of bodybuilding and eating disorders. Both are characterised by restrictive diets, high levels of exercise, potential social isolation, and adherence to a <a href="https://journals.lww.com/hrpjournal/Abstract/2019/07000/Competitive_Bodybuilding__Fitness,_Pathology,_or.3.aspx">rigid schedule</a>. The seminal <a href="https://www.sciencedirect.com/science/article/pii/S002231662210249X?via%3Dihub">Minnesota Starvation Experiment</a> fundamentally shaped our understanding of the changes a person can experience when they are consuming less than their daily nutrition energy needs, such as during the “cutting” phase for bodybuilders. This research showed that people who are experiencing starvation for a period of time will experience devastating impacts in the physical, psychological, behavioural and social aspects of their lives. Some of the many documented changes included reductions in heart muscle mass, heart rate and blood pressure, dizziness, fatigue, increased feelings of depression and anxiety, obsessive thoughts about food, and withdrawal from social activities and relationships. Concerningly, even once a person is renourished, the psychological issues around body size and food <a href="https://onlinelibrary.wiley.com/doi/abs/10.1002/eat.23095">can persist</a>. Therefore, even after an actor has returned to their pre-modification weight and size, it does not mean they have recovered from the consequences that came with that body modification. <h2>What are the impacts on the general public?</h2> Rapid changes in physical appearance are not realistically achievable for most people. So seeing actors doing this seemingly easily with the assistance of their professional teams sets an <a href="https://link.springer.com/article/10.1007/s40894-022-00179-4">unrealistic standard</a>. For people without the same income or access to resources to achieve these body modifications in a safe way, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8872588/">more extreme means</a> would be undertaken and consequent damage to mental and physical wellbeing can ensue. These body modifications are definitely a case of “do not try this at home”. There are many risks when undertaking dramatic body modifications, most of which are not talked about in public. Actors are just as vulnerable to these risks, despite us rarely seeing what exactly they go through to achieve these dramatic transformations. Hollywood is a highly competitive environment, and being honest about body modification and its consequences could stop an actor landing their next gig. We don’t recommend body modifications in any way, but if someone does want to make a change to their lifestyle, we strongly recommend consulting with a team of health professionals to ensure physical and psychological safety during the process and beyond. –– If this article has raised issues for you, or if you’re concerned about someone you know, do not hesitate to reach out for support.

Why is extreme ‘frontier travel’ booming despite the risks?

<a href="https://theconversation.com/profiles/anne-hardy-151480">Anne Hardy</a>, <a href="https://theconversation.com/institutions/university-of-tasmania-888">University of Tasmania</a>; <a href="https://theconversation.com/profiles/can-seng-ooi-399312">Can Seng Ooi</a>, <a href="https://theconversation.com/institutions/university-of-tasmania-888">University of Tasmania</a>; <a href="https://theconversation.com/profiles/hanne-e-f-nielsen-139245">Hanne E.F.

Cheer</a>, <a href="https://theconversation.com/institutions/western-sydney-university-1092">Western Sydney University</a> The world has watched in shock as rescue crews feverishly search for the <a href="https://oceangate.com/our-subs/titan-submersible.html">Titan</a> submersible vehicle, which <a href="https://www.theguardian.com/uk-news/2023/jun/19/titanic-tourist-submarine-missing-north-atlantic">disappeared</a> while attempting to take tourists to view the wreckage of the Titanic in the North Atlantic. The horror of the incident raises questions as to why people engage in risky tourism activities in remote locations and whether there should be more restrictions to what adrenaline-seeking tourists can do. <h2>What is frontier tourism?</h2> This type of travel, known as “<a href="https://research.monash.edu/en/publications/frontier-tourism-retracing-mythic-journeys">frontier tourism</a>”, is becoming big business. The wider adventure tourism industry is already worth <a href="https://www.futuremarketinsights.com/reports/adventure-tourism-market">billions of dollars</a> – and is growing quickly. Frontier tourism is an exclusive and extreme form of adventure travel. The trips are very expensive, aim to overstimulate the senses and go to the outer limits of our planet – the deep oceans, high mountains, polar areas – and even space. Frontier tourism is not new; humans have explored remote locations for millennia. Pasifika people used the stars to navigate the oceans for migration and trade. Europeans sailed to the edges of what they believed to be a flat Earth. In recent years, however, frontier tourism has attracted widespread attention thanks to the common occurrence of long queues on <a href="https://theconversation.com/70-years-after-the-first-ascent-of-everest-the-impact-of-mass-mountaineering-must-be-confronted-204270">Mount Everest</a>, the trending <a href="https://www.tiktok.com/discover/Drake-Shake">TikTok phenomenon</a> of crossing the #DrakePassage in <a href="https://theconversation.com/more-than-100-000-tourists-will-head-to-antarctica-this-summer-should-we-worry-about-damage-to-the-ice-and-its-ecosystems-192843">Antarctica</a> and the rapid development of <a href="https://theconversation.com/virgin-galactics-use-of-the-overview-effect-to-promote-space-tourism-is-a-terrible-irony-206868">space tourism</a> for the wealthy. The rise of travel content sharing on social media and <a href="https://www.tandfonline.com/doi/abs/10.1080/10548408.2021.2006858?journalCode=wttm20">revenge travel following COVID-19</a> have contributed to the surge in its popularity. <blockquote class="twitter-tweet"> When you’re happily having dinner and the ocean decides to scare the shit out of you!

Research <a href="https://doi.org/10.1177/0013916594261001">suggests</a> engaging in risky tourism activities, such as scaling a high mountain, can bring about feelings of accomplishment and euphoria. Travellers report feeling alive and experiencing a sense of transformation. Some are also <a href="https://doi.org/10.1080/09669582.2021.1897131">attracted</a> to the pristine, untouched and remote aspects of the locations that they visit. Furthermore, the <a href="https://www.nytimes.com/2023/06/20/movies/james-cameron-titanic.html">element of fantasy</a> associated with imagining certain places or stories, like the movie Titanic, can be alluring. Besides physical frontiers, there is also the <a href="https://www.cabidigitallibrary.org/doi/10.1079/9781780642093.0111">thrill people get</a> at pushing the human body to its limits and facing one’s fears. Base-jumping, skydiving, bungee jumping and polar plunges are common examples of this. In a slightly more mundane way, even tasting “<a href="https://journals.sagepub.com/doi/10.1177/1356766709104271">scary food</a>” pushes tourists outside of their comfort zone and helps them <a href="https://www.insider.com/harvard-psychologist-why-wealthy-seek-high-risk-trips-titanic-space-2023-6">feel alive</a>. Still others make extreme tourist journeys to follow in the <a href="https://www.nebraskapress.unl.edu/nebraska/9781496221216/">footsteps of their heroes</a>, such as those who travel to Antarctica to pay homage to explorer Ernest Shackleton. Extreme and risky activities not only make participants feel euphoric, but they also convey status. When bucket lists are ticked off and experiences shared on social media, this brings bragging rights. <a href="https://www.cambridge.org/core/journals/polar-record/article/from-awe-to-satisfaction-immediate-affective-responses-to-the-antarctic-tourism-experience/2B65FEDCEF9D7DEBB689C39C93549702">Research</a> suggests many travellers seek recognition for undertaking the first, longest or most extreme experiences possible. But frontier tourism is clearly not for all. It is usually only accessible to a privileged few, as the tragic circumstances of the Titan highlight. Passengers onboard the vessel reportedly paid <a href="https://www.bbc.com/news/world-us-canada-65953872">US$250,000</a> for the voyage. <h2>What are the impacts of frontier tourism?</h2> Beyond the unspeakable angst that friends and family must endure when things go wrong, there are many other impacts of this form of tourism. This type of travel can create <a href="https://www.taylorfrancis.com/chapters/edit/10.4324/9781003219866-11/tourist-experiences-attention-products-seng-ooi">environmental harm and negatively impact local communities</a>. For example, after decades of mass mountaineering, the environmental <a href="https://theconversation.com/70-years-after-the-first-ascent-of-everest-the-impact-of-mass-mountaineering-must-be-confronted-204270">impact</a> on Mount Everest must be addressed. And when mishaps do occur, the cost of search and rescue efforts can be massive and put rescue teams at great risk. The plight of frontier tourists are usually the focus of media reports, while emergency responders are often overlooked. Recent efforts by sherpas such as <a href="https://www.netflix.com/au/title/81464765">Nimsdai Purja</a> are trying to overcome this issue. Through the Netflix documentary, 14 Peaks, he publicises the behind-the-scene preparations and heavy lifting work done by sherpas who guide and rescue tourists up Everest and other mountains. <blockquote class="twitter-tweet"> Climbers have been filmed crushed together in a “human traffic jam” as they battle the elements in an attempt to reach the summit of Mount Everest.

Tourists also increasingly feel able to embark on trips once perceived as too dangerous because technology and other innovations have ostensibly made them safer and more accessible. In many instances that danger remains, but the commercial transaction <a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/j.1835-9310.2002.tb00213.x">strips away the perceived risks</a> involved. Marketing materials aim to sell “safe” adventures, with the risks are often listed in the fineprint. A <a href="https://www.tandfonline.com/doi/full/10.1080/11745398.2017.1286512">polar plunge</a> in Antarctica, for instance, is often marketed as safe because participants are attached to a tether and the swim time is limited to prevent hypothermia. Two decades ago, in forecasting the growth of space tourism, anthropologist Valene Smith <a href="https://www.tandfonline.com/doi/pdf/10.1080/02508281.2000.11014920">said</a> what tourists want, the industry will provide. This has become a truism, as the Titan voyages demonstrate. The massive growth of frontier tourism could lead to even greater problems if the industry doesn’t respond in the right way. If travellers are going to expose themselves to extreme risks, whose responsibility is it, then, to ensure their safety and recovery should accidents occur? Many tourism businesses and travel insurance companies make risks known to their guests. But regulations on disclosing risks differ between countries. These means travellers may have to evaluate the risks themselves, and this is fraught with danger if company standards are low. One solution is frontier tourism might be best experienced in controlled and safe environments through <a href="https://www.tandfonline.com/doi/full/10.1080/14616688.2023.2224043">digital storytelling</a> or <a href="https://www.mdpi.com/2071-1050/15/4/3348">augmented and mixed reality</a>. However, this may not be enough to satisfy the adrenaline junkies out there. As the Titan incident illustrates, the unpredictable nature and unintended consequences of frontier tourism are very real things. While money can allow us to travel almost anywhere, it’s worth considering whether some places should just remain untouched, sacred and off limits completely.<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/208201/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/anne-hardy-151480">Anne Hardy</a>, Associate Professor, Tourism and Society, <a href="https://theconversation.com/institutions/university-of-tasmania-888">University of Tasmania</a>; <a href="https://theconversation.com/profiles/can-seng-ooi-399312">Can Seng Ooi</a>, Professor, <a href="https://theconversation.com/institutions/university-of-tasmania-888">University of Tasmania</a>; <a href="https://theconversation.com/profiles/hanne-e-f-nielsen-139245">Hanne E.F.

Travel Tips

3 reasons you feel hungrier and crave comfort foods when the weather turns cold

As we move through Autumn, parts of Australia are starting to see cooler weather. For some of us, that can mean increasing feelings of hunger and cravings for “comfort food” such as as pasta, stews and ramen. But what’s happening in our body? <h2>3 things change when it gets cold</h2> 1. Our body conserves heat It sends this energy it conserves to our internal organs so they can maintain their temperature and work properly. The body can also perform heat-generating activities (such as shivering), which uses <a href="https://pubmed.ncbi.nlm.nih.gov/21261804/">energy</a>. The body will then look for additional energy through calories from eating food. 2. Our body warms up when eating When we eat, the body needs to expend energy to digest, absorb, and metabolise the nutrients. This process requires the use of energy, which generates heat in the body, leading to an increase in body temperature termed “<a href="https://pubmed.ncbi.nlm.nih.gov/36012714/">diet-induced thermogenesis</a>”. However, the amount of energy used to keep us warm is quite <a href="https://www.sciencedirect.com/topics/medicine-and-dentistry/nonshivering-thermogenesis">modest</a>. 3. Some people experience a drop in the neurotransmitter called serotonin This is partly because the rate our body produces serotonin is related to <a href="https://www.thelancet.com/pdfs/journals/lancet/PIIS0140673602117375.pdf">sunlight</a>, which is lower in winter. Serotonin helps to regulate mood, appetite, and sleep, among other things. When serotonin levels are low, it can lead to increased hunger and decreased satiety (feeling that you’ve had enough to eat), making us feel hungrier and less satisfied after meals. <h2>Why we love comfort food in winter</h2> Many of us struggle to eat salad in winter and crave mum’s chicken soup or a slow cooked, brothy ramen. Research shows our brain detects the cold weather and looks for warm <a href="https://www.mdpi.com/2072-6643/9/6/592">food</a>. Warm food can provide a sense of comfort and cosiness, which is particularly appealing during the colder months when we spend more time indoors. <a href="https://www.sciencedirect.com/science/article/pii/S1878450X16300786">Comfort food</a> can mean something different for everyone. They are foods we reach for in periods of stress, nostalgia, discomfort (like being cold), or emotional turmoil. For most of us, the foods we often over-indulge in are rich and carbohydrate heavy. A drop in serotonin has also been shown to stimulate an urge to eat more <a href="https://pubmed.ncbi.nlm.nih.gov/16340952/">carbohydrate-rich</a> foods such as gnocchi, pasta, ragout, mashed potatoes. <h2>What happens to those extra calories?</h2> If you consume more energy in cooler weather, some of it will be used to keep you warm. Beyond keeping us warm, extra calories we consume are stored. While most humans today have access to a year-round food supply, some research shows our bodies may still have some leftover instincts related to storing energy for the cooler months when food was harder to come by. This behaviour may also be driven by biological factors, such as changes in hormone levels that regulate appetite and <a href="https://www.frontiersin.org/articles/10.3389/fnins.2013.00140/full">metabolism</a>. A fundamental principle of nutrition and metabolism is that the balance between the energy content of food eaten and energy expended to maintain life and to perform physical work affects body <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3302369/">weight</a>. This means any excess energy that we don’t use will be stored – usually as fat. Using mathematical modelling, researchers <a href="https://royalsocietypublishing.org/doi/10.1098/rspb.2015.2443">have predicted</a>weight gain is more likely when food is harder to find. Storing fat is an insurance against the risk of failing to find food, which for pre-industrial humans was most likely to happen in winter. <h2>It doesn’t have to be unhealthy</h2> No matter your cravings during cooler months, it’s important to remember your own personal health and wellbeing goals. If you’re worried about excess energy intake, a change in season is a great time to rethink healthy food choices. Including lots of whole fresh vegetables is key: think soups, curries, casseroles, and so on. Including protein (such as meat, fish, eggs, legumes) will keep you feeling fuller for longer.

Floods, cyclones, thunderstorms: is climate change to blame for New Zealand’s summer of extreme weather?

The final months of New Zealand’s summer carried a massive sting, bringing “unprecedented” rainfalls several times over, from widespread flooding in Auckland at the end of January to ex-tropical Cyclone Gabrielle dumping record rains and causing devastating floods across the east coast of the North Island. After all that, New Zealand experienced spells of thunderstorms, bringing repeat floods to parts of Auckland and then Gisborne. The obvious question is what role climate change plays in these record-breaking rainfalls. Some answers come from the international <a href="https://www.worldweatherattribution.org/">World Weather Attribution</a> team, which today released a <a href="https://spiral.imperial.ac.uk/bitstream/10044/1/102624/10/Scientific%20report%20New%20Zealand%20Floods.pdf">rapid assessment</a> which shows very heavy rain, like that associated with Cyclone Gabrielle, has become about four times more common in the region and extreme downpours now drop 30% more rain. The team analysed weather data from several stations, which show the observed increase in heavy rain. It then used computer models to compare the climate as it is today, after about 1.2℃ of global warming since the late 1800s, with the climate of the past. The small size of the analysed region meant the team could not quantify the extent to which human-caused warming is responsible for the observed increase in heavy rain in this part of New Zealand, but concluded it was the likely cause. <h2>More energy in the atmosphere and ocean</h2> Many factors add to the strength of a storm and the intensity of rainfall, especially for short bursts. A crucial factor is always the amount of energy available. Climate change is increasing that amount of energy in two main ways. First, everything is getting warmer. Rising sea surface temperatures provide <a href="https://sciencebrief.org/uploads/reviews/ScienceBrief_Review_CYCLONES_Mar2021.pdf">extra fuel for the development of tropical cyclones</a> because they grow by heating from below. Warmer seas mean potentially faster development of tropical cyclones, and stronger, more vigorous storms overall. Sea temperatures must be at least 26.5℃ to support the build-up of a tropical cyclone. So, as the oceans warm, these storms can reach farther from the equator. Second, warmer air can hold more water vapour. Every degree of warming increases the maximum amount of water vapour by around 7%. That extra water vapour tends to fall out as extra rain, but it also provides extra energy to a storm. <h2>Driving waves further inland</h2> The energy it takes to evaporate the water from the ocean surface and turn it into vapour is released again when the vapour condenses back into liquid water. A moister airmass heats the atmosphere more when clouds and rain form, making the air more buoyant and able to rise up more. This creates deeper, more vigorous clouds with stronger updrafts, and again more rain. Stronger updrafts in a storm mean more air will have to be drawn into the storm near the Earth’s surface, ensuring more “convergence” of air and moisture (water vapour). That’s why, even though a degree of warming translates to 7% more water vapour in the air, we can get 20% increases, or larger, in extreme rainfalls. All of this extra energy can contribute to making the storm stronger overall, with stronger winds and lower air pressures in its centre. This seems to have happened with Cyclone Gabrielle. Record low pressures were recorded at a few North Island locations as the storm passed. The low pressures act like a vacuum cleaner, sucking the sea surface up above normal sea level. The strong winds can then drive waves much further inland. Add in a bit of sea-level rise, and coastal inundation can get a lot worse a lot quicker. As the climate continues to change, storm intensity is likely to increase on average, as sea levels continue to rise. Those effects together are bound to lead to more dramatic coastal erosion and inundation. <h2>Thunderstorms riding warming seas</h2> These processes work for thunderstorms as well. A thunder cloud often starts as a buoyant mass of air over a warm surface. As the air rises (or convects), it cools and forces water vapour to condense back to liquid water, releasing heat and increasing the buoyancy and speed of the rising air. Again, that allows more moist air to be drawn into the cloud, and that convergence of moist air can increase rainfall amounts well above the 7% per degree of warming, for short bursts of very intense convection. The more intense the convection, the stronger the convergence of moisture and the heavier the resulting rainfall. Tropical cyclones have rings of thunderstorms around their eye during the time when they are truly tropical storms. As they transition out of the tropics into our neighbourhood, they change their structure but retain a lot of the moisture and buoyancy of the air. An ex-tropical cyclone like Gabrielle, moving over very warm water, can pack a devastating punch. Why has New Zealand had so much of this very heavy rain during the weeks from late January? Partly it’s the very warm ocean waters around Aotearoa (up to marine heatwave conditions) and farther north into the Coral Sea. That itself is partly related to the ongoing La Niña event in the tropical Pacific, which tends to pile up warm water (and tropical cyclones) in the west. But it is also related to ongoing global warming. As sea temperatures increase, it becomes easier to reach heatwave conditions. Warmer seas load the atmosphere with water vapour. Partly, too, the air over the North Island has been unusually “unstable” lately, very warm near ground level but cooler than normal higher up. That makes the buoyance in thunderstorms work even better and more strongly, encouraging very heavy rainfall. These conditions seem to have eased now, but severe thunderstorms continue to develop. As we move from summer into autumn, as the warmest seas move eastwards away from us and as La Niña fades in the tropics, the chances of a repeat event are diminishing. For now at least. But if we continue to warm the climate with more greenhouse gas emissions, we will continue to load the dice towards more very heavy rain over Aotearoa. Let us hope those regions and communities so badly affected by recent events have a chance to dry out, rebuild and recover before the next extreme weather.

Can ideology-detecting algorithms catch online extremism before it takes hold?

Ideology has always been a critical element in understanding how we view the world, form opinions and make political decisions. However, the internet has revolutionised the way opinions and ideologies spread, leading to new forms of online radicalisation. Far-right ideologies, which advocate for ultra-nationalism, racism and opposition to immigration and multiculturalism, have proliferated on social platforms. These ideologies have strong links with violence and terrorism. In recent years, <a href="https://www.asio.gov.au/sites/default/files/2022-02/ASIO_Annual_Report_2020-21.pdf">as much as 40%</a> of the caseload of the Australian Security Intelligence Organisation (ASIO) was related to far-right extremism. This has <a href="https://www.abc.net.au/news/2023-02-13/right-wing-terror-threat-declines-says-asio/101965964">declined</a>, though, with the easing of COVID restrictions. Detecting online radicalisation early could help prevent far-right ideology-motivated (and potentially violent) activity. To this end, we have developed a <a href="https://arxiv.org/abs/2208.04097">completely automatic system</a> that can determine the ideology of social media users based on what they do online. <h2>How it works</h2> Our proposed pipeline is based on detecting the signals of ideology from people’s online behaviour. There is no way to directly observe a person’s ideology. However, researchers can observe “ideological proxies” such as the use of political hashtags, retweeting politicians and following political parties. But using ideological proxies requires a lot of work: you need experts to understand and label the relationships between proxies and ideology. This can be expensive and time-consuming. What’s more, online behaviour and contexts change between countries and social platforms. They also shift rapidly over time. This means even more work to keep your ideological proxies up to date and relevant. <h2>You are what you post</h2> Our pipeline simplifies this process and makes it automatic. It has two main components: a “media proxy”, which determines ideology via links to media, and an “inference architecture”, which helps us determine the ideology of people who don’t post links to media. The media proxy measures the ideological leaning of an account by tracking which media sites it posts links to. Posting links to Fox News would indicate someone is more likely to lean right, for example, while linking to the Guardian indicates a leftward tendency. To categorise the media sites users link to, we took the left-right ratings for a wide range of news sites from two datasets (though many are available). One was <a href="https://reutersinstitute.politics.ox.ac.uk/our-research/digital-news-report-2018">based on a Reuters survey</a> and the other curated by experts at <a href="https://www.allsides.com/media-bias/ratings">Allsides.com</a>. This works well for people who post links to media sites. However, most people don’t do that very often. So what do we do about them? That’s where the inference architecture comes in. In our pipeline, we determine how ideologically similar people are to one another with three measures: the kind of language they use, the hashtags they use, and the other users whose content they reshare. Measuring similarity in hashtags and resharing is relatively straightforward, but such signals are not always available. Language use is the key: it is always present, and a known indicator of people’s latent psychological states. Using machine-learning techniques we found that people with different ideologies use different kinds of language. Right-leaning individuals tend to use moral language relating to vice (for example, harm, cheating, betrayal, subversion and degradation), as opposed to virtue (care, fairness, loyalty, authority and sanctity), more than left-leaning individuals. Far-right individuals use grievance language (involving violence, hate and paranoia) significantly more than moderates. By detecting these signals of ideology, our pipeline can identify and understand the psychological and social characteristics of extreme individuals and communities. <h2>What’s next?</h2> The ideology detection pipeline could be a crucial tool for understanding the spread of far-right ideologies and preventing violence and terrorism. By detecting signals of ideology from user behaviour online, the pipeline serves as an early warning systems for extreme ideology-motivated activity. It can provide law enforcement with methods to flag users for investigation and intervene before radicalisation takes hold.

Europe warming at double the rate of other continents

Europe is the fastest-warming continent in the world, according to a newly released report from the World Meteorological Organization. The State of the Climate in Europe report cites the loss of more than 25 metres of ice loss in alpine glaciers, and 20 metres of loss in Greenland (a Danish territory), as particularly responsible for the rise in ocean levels. Climate change events were also responsible for more than US$50 billion in damages. In its statement releasing the report, the WMO described Europe as the “live picture” of a world burdened by warming climate. Since 1990, Europe’s temperatures have undergone an average rate of temperature increase of 0.5 degrees each decade. That rate is twice as high as the next fastest warming continent. The WMO points to high-impact weather and climate events – nearly 85% of which were floods and storms – as directly affecting around 510,000 people. Extreme heat also took its toll, with provisional record temperatures experienced in southern Italy in August reaching 48.8°C. These temperatures influenced drought and low rainfall across the Mediterranean, leading to deadly wildfires that burned through three times the amount of land area than the region’s 15-year average up to 2020. <h2>But are carbon emissions decreasing in Europe?</h2> Fuel prices and the COVID-19 pandemic were major influences on the continent’s carbon emissions reduction, the WMO found. A 31% decline in carbon emissions between 1990 and 2020 was recorded, although it’s expected to be far less in 2021 due to the relaxation of COVID-19 restrictions and altered fuel prices. 2021 also marked the introduction of EU legislation to make net zero by 2050 a legally-binding target for member nations. Although temperature data provided by six datasets showed a decrease in 2021 from the preceding year, it still marked one of the 10 warmest years on record. And observers will keenly await the release of next year’s 2022 appraisal, after record summer droughts and heatwaves heaped pressure on European nations. Even now, regions across the continent are recording their hottest temperatures for November on record. <blockquote class="twitter-tweet"> (2) More November records in Europe. France had 21 records today (left column), the most important were: Aigues Mortes (POR since 1872), Aix en Provence and Valence (1st class stations).

In 2021, exceptional floods caused death and devastation. “On the mitigation side, the good pace in reducing greenhouse gases emissions in the region should continue and ambition should be further increased. Europe can play a key role towards achieving a carbon neutral society by the middle of the century to meet the Paris Agreement.” <h2>Future outlook</h2> The release of the report comes ahead of the global climate change conference to be held in Egypt, where delegations from around the world convene to recalibrate efforts to address climate change. Last year’s COP26 conference in Glasgow was criticised for scrubbing language to phase out coal from the final agreement. In its place came language to ‘phase down’ its use. Coal is the leading source of carbon emissions from energy use. Similarly, several nations failed to renew important targets to reduce carbon emissions by the end of the decade, considered an important tipping point if net zero by 2050 is to be achieved. The WMO echoed the most recent Intergovernmental Panel on Climate Change forecasts that weather, climate and water disasters will increase in the future, and that Europe will experience temperature rises at rates exceeding global average increases.

Disabled woman slams Jetstar for “extremely humiliating” treatment

A woman has said she was humiliated at the end of her flight after Jetstar staff couldn’t provide her with a wheelchair for her, forcing her to leave the plane by crawling. Natalie Curtis has been in a wheelchair since high school but said she has never been as humiliated as she was left to crawl to her wheelchair after flying from Singapore to Bangkok. While she was provided a standard “aisle” wheelchair to board the plane, Ms Curtis was told she would have to pay to use another chair to get off the plane - a service which is usually free. “I didn’t really comprehend it and I was like, ‘No, I’m not paying to be able to get off this plane’,” Ms Curtis told Sunrise. With her friend Natasha Elford unable to carry her due to a knee injury, Ms Curtis crawled on the floor past eight rows until she could reach her chair. “It was extremely humiliating,” she said. Ms Elford said she was in shock while watching the ordeal and that she was “absolutely gutted”. “I was like, ‘Is this actually happening?’” she told the program on Monday. “I couldn’t physically lift her so I felt really hopeless and I couldn’t believe this was really happening.” She added that she tried to find out if a wheelchair could be fast tracked to Ms Curtis, but said the flight attendants “didn’t really try to do anything”. <iframe style="overflow: hidden; border: initial none initial;" src="https://www.facebook.com/plugins/post.php?href=https%3A%2F%2Fwww.facebook.com%2Fnatalie.hodges.50%2Fposts%2Fpfbid0ewJHd3156WaV46vd8LHJWCwLrxBQraSgSfAP1dZqcfPc47oo4WkNmCj7VWjda6Rl&show_text=true&width=500" width="500" height="393" frameborder="0" scrolling="no" allowfullscreen="allowfullscreen"></iframe> A spokesperson for the budget airline said Jetstar had sincerely apologised to Ms Curtis and had offered her a refund and additional compensation. “We unreservedly apologise to Ms Curtis for her recent experience while travelling with us,” they said. “We are committed to providing a safe and comfortable travel experience for all our customers, including those requiring specific assistance.” The spokesperson added that Jetstar staff don’t charge for using a wheelchair, and that an inquiry into the incident had found a language barrier led to the miscommunication of a fee. “At no point was an aisle chair withheld due to a request for payment,” they said. Ms Curtis isn’t the only person to have experienced such an incident over wheelchair use, and her experience comes as disability advocates call for a complete overhaul of the treatment of passengers by airlines. In August, Brad Wszola had to be carried by his wife and a staff member over the gap between the air bridge and the Jetstar plane he was trying to board to fly from Darwin to Cairns, per <a href="https://www.theguardian.com/society/2022/oct/06/second-class-citizen-man-lifted-on-to-plane-as-darwin-airport-had-no-ramp-for-wheelchair-users" target="_blank" rel="noopener">The Guardian</a>. “Watching these people having to lift me, to bend down, Jen had to bend down below the level of the floor of the plane, bend over and grab the bottom of the aisle chair to lift me … That put myself at risk, also the staff at risk and Jenny at risk,” Mr Wszola said. “She was the one helping lift me into the plane.” Mr Wszola even encountered issues prior to leaving Darwin, with his wheelchair being sent to the baggage carousel rather than the air bridge on his arrival. After his wife made multiple requests via email to Darwin airport and Jetstar, she was told a ramp wasn’t provided to bridge the gap as it was a low-cost airline - but a ramp has since been provided to the airport after The Guardian contacted Jetstar. <blockquote class="twitter-tweet"> Just made a cute little video about how <a href="https://twitter.com/Qantas?ref_src=twsrc%5Etfw">@Qantas</a> broke my wheelchair and won’t fix it 🙃🙃🙃🙃 <a href="https://t.co/CnFXazJ1ox">pic.twitter.com/CnFXazJ1ox</a> — Zoe Simmons | she/her (@ItbeginswithZ) <a href="https://twitter.com/ItbeginswithZ/status/1577502974796247041?ref_src=twsrc%5Etfw">October 5, 2022</a></blockquote> Earlier this month, Qantas reversed its decision not to refund Zoe Simmons, whose wheelchair was damaged on a flight from Sydney to Canberaa, after she took her complaints to social media. In a column for <a href="https://www.news.com.au/travel/travel-advice/flights/disability-advocate-lashes-qantas-over-broken-wheelchair/news-story/72ae759ca7960ab607610c5ebd6c8bca" target="_blank" rel="noopener">news.com.au</a>, Simmons explained that damage to her chair brakes had left it “unusable” and was initially told Qantas wouldn’t reimburse her or repair her chair, which she needs as someone living with the nerve disorder fibromyalgia. “I am so angry that this is how wheelchair users are treated by airlines, over and over. And it’s not just Qantas: it’s a systemic issue, because the system is so very broken,” she wrote. With the airline reaching out to apologise and offering to pay for her wheelchair repairs, Simmons questioned whether she would have received such a response if she hadn’t taken matters into her own hands. “I wonder: would this resolution have occurred, had I not made a fuss about it?” she wrote. “I shouldn’t have to hope to be an exception to the norm. The norm should be that disabled people are looked after, treated well, and able to get the same resolution I’ve been able to get here.” Image: Sunrise

5 places in the world that have the best weather

It’s just about the first question anyone asks you when you return from a holiday – “how was the weather?” It can make or break a holiday. These are the places you should go if you want to leave the wellies at home. Los Angeles <img src="https://oversixtydev.blob.core.windows.net/media/2022/10/los-angeles.jpg" alt="" width="1280" height="720" /> California is a pretty safe bet all round and has easily the best weather in the USA. You can expect “perfect” days for close to half the year. That means an average temperature between 12 and 23 degrees Celsius, and temperatures that never fall below seven degrees or rise above 30. And on top of that there’s almost no rain. Sounds pretty good to us. Canary Islands <img src="https://oversixtydev.blob.core.windows.net/media/2022/10/canary-islands2.jpg" alt="" width="1280" height="720" /> This island group off the northern coast of West Africa is technically a Spanish territory and a popular holiday spot for the Brits. With an average temperature of 22 degrees Celsius all year round and no extremes of hot or cold, the Canaries claim to have the best climate in the world. The capital, Gran Canaria, gets a minimum of six hours of sunshine per day in winter and up to almost eight hours in summer. Plenty of time then to indulge in a round of golf – there are eight world-class courses on the island. Sao Paulo <img src="https://oversixtydev.blob.core.windows.net/media/2022/10/sao-paulo.jpg" alt="" width="1280" height="720" /> Whatever time of year you visit Brazil’s largest city, you probably won’t need to bring a jacket. Even in the middle of winter (July or August) temperatures rarely get below 20 degrees and they don’t rise much over 30 in summer. It can be rainy, but the city rarely gets big storms. Its inland location and high elevation work together to create a perfect microclimate. This is in contrast to the coastal city of Rio de Janeiro, just 400 kilometres away, which swelters through the hotter months. Lisbon <img src="https://oversixtydev.blob.core.windows.net/media/2022/10/lisbon.jpg" alt="" width="1280" height="720" /> The Portuguese capital sits on the Atlantic coast, which moderates its weather and helps it avoid the uncomfortably hot summers that you’ll find in many other European capitals. Lisbon gets around 30 inches of rain each year but the majority of this falls during winter, so you’re likely to get weeks on end of pure sunshine in the summer months. Sydney <img src="https://oversixtydev.blob.core.windows.net/media/2022/10/opera-house7.jpg" alt="" width="1280" height="720" /> Despite Australia having some of the most extreme weather in the world, Sydney is famous for its dry summers, mild winters and endless hours of sparkling sunshine. Even a run of cold days is quickly forgotten when the harbour city turns on a warm, sunny August afternoon. Images: Getty Images

“I had to reach the island”: Aussie mum recalls terrifying turn on cruising scuba dive

A NSW woman has said a cruise company should have been better prepared for adverse weather after a holiday scuba dive nearly went horribly wrong. Justine Clark and her sons, 18-year-old Felix and 20-year-old Max, resurfaced from an offshore dive in Fiji to find that their boat was nowhere to be seen. The trio were on a seven-day cruise in Fiji when they went on an afternoon dive at an offshore site called The Supermarket with another cruise-goer and the divemaster, who worked for a company subcontracted by Captain Cook Cruises Fiji. Though the weather began to worsen as they travelled to the dive site, the party pushed on. "We travelled into an approaching storm and out into open waters in what appeared to be a large channel about 20 kilometres from any island," Ms Clark told the <a href="https://www.abc.net.au/news/2022-09-21/fiji-dive-turns-into-nightmare-for-newcastle-mum-and-sons/101448116" target="_blank" rel="noopener">ABC</a>. When she resurfaced with her eldest son after a dive of about 40 minutes, she said the boat was nowhere to be seen and the weather conditions were rough. <img src="https://oversixtydev.blob.core.windows.net/media/2022/09/justine-cruise-nightmare1.jpg" alt="" width="1280" height="720" /> A tender boat took Justine Clark, her two sons, and others in their diving party to the dive site. Image: Justine Clark "No tender boat was visible on surfacing, the swell was 2 metres, it was dark with grey clouds and high wind," she said. Ms Clark, who has over 30 years of diving experience, said their divemaster was the next to surface and realise what had happened. "He was shocked at the events and stated this had never happened in his 27 years of diving," she recalled. When the divemaster then advised the group to start swimming for an island they could see in the distance, Ms Clark said she was determined to stay calm. "I can't impress how concerned I was for everyone's health, sharks and the sense of determination I had to reach the island in a calm manner," she continued. "The maternal drive in me was something I had not felt since the birth of my first son." After about 50 minutes, a small boat was spotted travelling towards the group, with the divemaster telling them to inflate their surface marker buoys so they could be seen more easily. The boat’s operator, a garbage collector who had been picking up ocean rubbish, noticed the tip of one of the buoys. "We were all smiles and I was blowing a kiss to the Fijian who saved us," Ms Clark said. They were quickly found by the tender boat driver. "He apologised and told me he was so scared and he had radioed the captain that he lost us," Ms Clark said. In a written response shared with the outlet, Captain Cook Cruises Fiji explained that the tender boat had blown away from the site, with the surface conditions making it difficult for the operator to find and follow the divers’ bubbles. The cruise operator said the situation was unprecedented and that changes were made to the “already tight” safety procedures following an internal review. Though rare, Ms Clark said cruise companies should still be prepared. "I think it's really important that operators are prepared for those situations that may be rare but can still occur," she said. It isn’t the first time bad weather has caused strife for cruise ships this year, after wild weather prevented the Coral Princess and other 20 other vessels from docking in Brisbane for several days in July, prompting 2,000 cruise passengers to be stranded onboard.

Best cold weather workouts you can do from the comfort of home

Although most of us will be tempted to hit snooze on those colder mornings, the chilly season doesn’t mean we have to hibernate our fitness routines. With a vast library of content, <a href="https://www.onepeloton.com.au/home-trial?utm_source=google&utm_medium=search&utm_campaign=portfolio&gclsrc=aw.ds&gclid=CjwKCAjwi8iXBhBeEiwAKbUofZ2cinznTjKrGyrUBTp1P0c5mEGYJTdPZxy1Yq9RiKTabUq6095i1RoCEb4QAvD_BwE" target="_blank" rel="noopener">Peloton</a> provides a digital fitness experience with convenience at its centre – allowing you to work out anywhere, anytime, all while catering to your individual fitness goals and ability. Leading cardiologist and member of the Peloton Health and Wellness Advisory Council, Dr Suzanne Steinbaum says, “Exercising throughout the year can decrease the major risk factors associated with heart disease and help manage cholesterol, blood pressure, sugars, weight and stress levels, which in turn can dilate the arteries and maximise cardiac functioning. Structured workouts, like Peloton’s range of HIIT and low-impact classes, can motivate and help you stay on track, while also being part of a vibrant community that supports and cheers you on, while working out at your own pace”. Peloton has curated the best workouts to overcome the winter woes and develop a regular fitness routine. 1. Strength: Lean muscle mass naturally diminishes as we age. Choose a strength training class, starting with a beginner workout such as <a href="https://members.onepeloton.co.uk/classes/player/dda80a799bf64531ba1e2947a0896df6" target="_blank" rel="noopener">20 Min Strength Roll Call with Jess Sims</a> to develop stronger bones, manage chronic conditions as well as regulate your weight and improve your heart's strength. The great thing about strength training in winter is you can do it inside with whatever you have available or use the <a href="https://www.onepeloton.com.au/guide" target="_blank" rel="noopener">Peloton Guide</a> if you want to take your workout to the next level. With the Peloton Guide, or by using the Peloton App on your TV, you can turn your living room into a home gym enhanced by a guided workout experience with features including a Movement Tracker to keep you accountable. It’s always important to remember that even when working out from home, ensure that you are exercising safely and are aware of your surroundings in order to prevent injury. 2. Warm-up class: A 15-minute warm-up can be the push you need to get going in the morning. Instead of reading the news or flicking through the TV channels, scroll through the various warm-up classes offered on the <a href="https://www.onepeloton.com/app" target="_blank" rel="noopener">Peloton App</a>. A warm-up class can help you feel more energised and focused for the day ahead and is good for the mind as well as the body. Once you've started, you’ll likely feel exhilarated from the music that you'll want to keep going with a full class. Sometimes just getting started is the hardest part, but once your heart starts beating and blood starts flowing, you will feel energised and motivated particularly on those cold days.. 3. Cardio: If you'd rather just get right into it, a solid HIIT (High-Intensity Interval Training) workout usually lasts 20 to 30 minutes, with classes available on the Peloton App as well as the Bike. The winter air can help improve your endurance for cardio exercises, therefore you might use this indoor time to get into a routine and create a regular exercise program. Plan to take a 20-30 minute class where you get your heart rate up at least 5 days a week for maximum benefit. Choose a HIIT class from the <a href="https://www.onepeloton.com/app" target="_blank" rel="noopener">Peloton App</a> to boost your heart rate to not only keep you warm but improve your cardiovascular health. Dr Suzanne Steinbaum, says: “High-intensity interval training, or HIIT, workouts are popular for a reason: Studies suggest that these types of workouts can deliver the same health benefits of a moderate workout in half the time. It’s true, but only if you strike the right balance and work out on a consistent basis.” 4. Yoga: Although yoga might not be the first thing that comes to mind for a great workout, it actually has a lot of benefits. It helps to improve your flexibility, balance and increase you stamina. A 2016 <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4728955/" target="_blank" rel="noopener">study</a> also found that even bi-weekly yoga sessions can help with recovery, boost performance, strengthen your mental game, help with breathing more efficiently, open up tight hips, quads and hamstrings and build core strength. 5. Meditation: If you’re looking for something to help you stay centred all winter long, try a Peloton Meditation class from the comfort of your warm home. Bring a little more calm, focus and positive energy into your life, with Peloton’s range of meditation classes, many of whom are led by Peloton’s first Australian Instructor,<a href="https://www.onepeloton.com.au/instructors/peloton_l" target="_blank" rel="noopener">Kirra Michel</a>. Kirra stresses the importance of incorporating mindfulness and meditation in your exercise routine. “I might have a bias towards yoga and meditation as it's my passion. But, it's special in the fact it incorporates physical activity, breath work, and mindfulness. All of which positively affect cardiovascular risk factors. Modalities we conveniently have on the OnePeloton App!” About Peloton Peloton makes fitness entertaining, approachable, effective, and convenient while fostering social connections that motivate its members to commit to their fitness journeys. Australians can access the Peloton library with thousands of live and on-demand classes at the gym, at home, on the road, or wherever they choose to move, through the Peloton Bike, Peloton Bike+, Peloton Guide, and Peloton App on any iOS or Android device and select smart TVs.

Stunning finalists’ images for photography competition revealed

The phenomenal images from the finalists of the prestigious Weather Photographer of the Year have been revealed. Photographers from 119 countries submitted their stunning images which range from dramatic storms, frozen and frosty vistas, spectacular sunsets, impacts of climate change and curious weather phenomena. The talented professionals and amateur photographers were able to capture spectacular landscapes which are affected differently depending on the weather. Professor Liz Bentley, Chief Executive of the Royal Meteorological Society (RMetS) said the competition is an exciting opportunity to explore never before seen moments. “I am always amazed by something new, something I haven’t seen before, or a new angle that reignites my passion for discussing the weather,” she said. “As the competition has grown over the past seven years, it has allowed us to create a platform where more stories can be told about the majesty and awe of the world’s weather and witness scenes of the impacts of climate change, which can help to prompt action.” Members of the public will be able to vote for their favourite photograph with the winners expected to be announced on October 6.
