Who dies in a heat wave? How to help protect the vulnerable in our communities

<p><em><a href="https://theconversation.com/profiles/myles-david-sergeant-1542267">Myles David Sergeant</a>, <a href="https://theconversation.com/institutions/mcmaster-university-930">McMaster University</a></em></p> <p>Extreme heat is a silent killer.</p> <p>From time to time, we hear about shocking cases of <a href="https://www.theguardian.com/world/2023/sep/24/football-player-heat-deaths-athlete">football players</a> and other athletes who die suddenly while exerting themselves on hot days. Those deaths are certainly tragic, but statistically they are very rare.</p> <p>Most deaths from extreme heat <a href="https://www.epa.gov/climate-indicators/climate-change-indicators-heat-related-deaths">are in older people</a>, who frequently die alone inside their homes. They often die slowly, as the heat creeps up to and sometimes past body temperature, especially when heat domes park themselves over cities and keep the temperature high all day and all night. When such deaths happen, they rarely make the news.</p> <p>Of all the climate change disasters our world is already experiencing, heat is the top killer, <a href="https://library.wmo.int/viewer/68500/download?file=1335_WMO-Climate-services-Health_en.pdf&amp;type=pdf&amp;navigator=1">as the World Meteorological Organization reported</a>. The planet was more than <a href="https://www.theguardian.com/environment/article/2024/jul/08/temperatures-1-point-5c-above-pre-industrial-era-average-for-12-months-data-shows">1.5 C above the pre-industrial baseline</a> for 12 consecutive months from July 2023 to June 2024. In July this year, we saw the hottest three days ever on record, prompting <a href="https://www.un.org/sg/en/content/sg/press-encounter/2024-07-25/secretary-generals-press-conference-extreme-heat">a special statement from United Nations Secretary-General Antonio Guterres</a>.</p> <h2>Health risks and heat</h2> <p><a href="https://www.ncbi.nlm.nih.gov/books/NBK499843/">Our bodies are made to dump excess heat</a> when we are too warm, but that process goes into reverse when the air is warmer than our core temperature. Our other main defence, sweating, doesn’t help when humidity saturates the air, making it impossible for our own moisture to evaporate.</p> <p>For the frail and elderly, who are more likely to be labouring with heart troubles, COPD or other challenges, simply sitting still in a heat wave requires an effort equivalent to walking on a treadmill. The effort is not great, but it is <a href="https://doi.org/10.1016/j.cjco.2021.10.002">steady and relentless</a>. It exhausts the body, sometimes to the <a href="https://doi.org/10.1016/S2542-5196(22)00117-6">point of no return</a>.</p> <p>Tracking heat-related deaths is challenging, and it’s changing as authorities become more aware of heat as a contributing or underlying factor to deaths by other causes. <a href="https://doi.org/10.2105/AJPH.2006.100081">A paper published by the <em>American Journal of Public Health</em></a> points out that the 1995 heat wave in Chicago likely contributed to hundreds more deaths than had first been attributed to heat itself.</p> <h2>Who is at risk?</h2> <p>Many people lack air conditioning or a way to get to a place that has it, such as a library, recreation centre or shopping mall. As a result, too many people in cities are forced to <a href="https://wmo.int/publication-series/2023-state-of-climate-services-health">endure long waves of heat</a> — waves that are occurring more frequently, lasting longer, and reaching higher temperatures — in a trend that appears set to continue getting worse.</p> <p>Air conditioning, <a href="https://www.lpm.org/news/2015-07-24/the-history-of-movie-theaters-and-air-conditioning-that-keeps-film-lovers-cool">once a luxury that drew people to summertime movie theatres on hot nights</a>, has become a necessity. Increasingly, it is also a legal requirement, as cities pass bylaws requiring landlords not to allow the temperature in their tenants’ quarters to rise above a certain level. Toronto has <a href="https://www.toronto.ca/home/311-toronto-at-your-service/find-service-information/article/?kb=kA06g000001xvbiCAA">such a bylaw</a> for rental units that have air conditioning available, capping indoor temps at 26 C between June 2 and Sept. 14.</p> <p>Such laws recognize the vulnerability of tenants who lack control over the temperature in their rental units, making heat death an especially urban tragedy, as confirmed in <a href="https://www150.statcan.gc.ca/n1/en/pub/82-003-x/2024006/article/00001-eng.pdf?st=e6jLNMuq">a recent Statistics Canada study</a> between 2000 and 2020. Deaths from extreme heat were more likely in cities with a higher percentage of renter households.</p> <p>During a single week-long heat wave in June 2021 — the year after the period captured in the Statistics Canada study — <a href="https://www.cbc.ca/news/canada/british-columbia/bc-heat-dome-sudden-deaths-570-1.6122316">B.C.’s chief coroner found that 570 people died from heat-related causes</a> — 79 per cent of them were seniors.</p> <h2>Taking action at the community level</h2> <p>From this Global North perspective, the community members who are most likely to die from extreme heat included:</p> <ul> <li>Those over 65</li> <li>Those with more than one chronic condition (including hypertension, mental health, diabetes, heart disease, lung disease)</li> <li>Socially disadvantaged populations in our communities</li> <li>Those with mobility issues</li> <li>Those experiencing social isolation (living alone)</li> <li>Tenants with lack of air conditioning</li> <li>Those living in an urban heat island</li> </ul> <p>This problem is not going away.</p> <p>Some of the <a href="https://www.intactcentreclimateadaptation.ca/wp-content/uploads/2022/06/UoW_ICCA_2022_04-Irreversible-Extreme-Heat.pdf">actions we can take</a> to protect our most vulnerable community members include:</p> <ul> <li>Increase awareness that excessive heat is not merely uncomfortable, but dangerous.</li> <li>Make sure people are warned about impending heat waves.</li> <li>Advocate for everyone to have access to air conditioning.</li> <li>Check on and support people who live alone, especially those with no air conditioning.</li> <li>Invite people over if you have air conditioning, or help them get to community cooling stations.</li> <li>Help vulnerable people who do not have air conditioning to improvise, by freezing wet cloths, for example, to take out and hang around their necks.

How do heat protectants for hair work? A chemistry expert explains

<p><em><a href="https://theconversation.com/profiles/daniel-eldridge-1494633">Daniel Eldridge</a>, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a></em></p> <p>Heat can do amazing things to change your hairstyle. Whether you’re using a curling wand to get ringlets, a flat iron to straighten or a hair dryer to style, it’s primarily the heat from these tools that delivers results.</p> <p>This comes with casualties. While your hair is surprisingly tolerant to heat compared with many other parts of your body, it can still only withstand so much. Heat treatment hair appliances frequently operate at over 150°C, with some reportedly <a href="https://www.frontiersin.org/journals/bioengineering-and-biotechnology/articles/10.3389/fbioe.2019.00298/full#B13">reaching</a> <a href="https://www.researchgate.net/publication/289291195_Thermal_degradation_of_hair_I_Effect_of_curling_irons">over 200°C</a>. At these temperatures, your hair can end up fried.</p> <p>Many people use heat protectants, often in the form of sprays, to minimise the damage. So how do these protectants work? To answer that, I first have to explain exactly what heat does to your tresses on the molecular level.</p> <h2>What heat does to your hair</h2> <p>A large proportion of your hair is made up of proteins. There are attractive forces between these proteins, known as hydrogen bonds. These bonds play a big role in dictating the shape of your locks.</p> <p>When you heat up your hair, the total attraction of these hydrogen bonds become weaker, allowing you to more easily re-shape your hair. Then, when it cools back down, these attractions between the proteins are re-established, helping your hair hold its new look until the proteins rediscover their normal structure.</p> <p>The cuticle – the outermost protective layer of your hair – contains overlapping layers of cells that lose integrity when they’re heated, damaging this outer protective layer.</p> <p>Inside that outer layer is the cortex, which is rich in a protein called keratin.</p> <p>Many proteins don’t <a href="https://pubmed.ncbi.nlm.nih.gov/21635854/">hold up structurally</a> after intense heating. Think of cooking an egg – the change you see is a result of the heat altering the proteins in that egg, unravelling them into different shapes and sizes.</p> <p>It’s a <a href="https://library.scconline.org/v049n04/33">similar story</a> when it comes to heating your hair. The proteins in your hair are also susceptible to heat damage, reducing the overall strength and integrity of the hair.</p> <p>Heat can also affect substances called melanin and <a href="https://pubmed.ncbi.nlm.nih.gov/21443842/">tryptophan</a> in your hair, resulting in a change in pigmentation. Heat-damaged hair is <a href="https://pubmed.ncbi.nlm.nih.gov/21635854/">harder to brush</a>.</p> <p>The damage is even more devastating if you use heat styling tools such as <a href="https://labmuffin.com/why-you-should-never-straighten-or-curl-wet-hair/">curling irons or straighteners</a> to <a href="https://library.scconline.org/v062n01/23">heat wet hair</a>, as at the high treatment temperatures, the water soaked up by the fibres can violently evaporate.</p> <p>The result of this is succinctly described by science educator and cosmetic chemist Michelle Wong, also known as <a href="https://labmuffin.com/how-do-heat-protectant-hair-products-work/">Lab Muffin</a>. She notes if you heat wet hair this way, “steam will blast through your hair’s structure”.</p> <p>This steam bubbling or bursting through the hair can <a href="https://pubmed.ncbi.nlm.nih.gov/21443842/">cause substantial damage</a>.</p> <p>It’s worth noting hair dryers don’t concentrate heat in the same way as styling tools such as flat irons or curling wands, but you still need to move the hair dryer around constantly to avoid heat building up in one spot and causing damage.</p> <p>Once heat damage is done, regardless of whether it is severe or mild, the best remaining options are symptom management or a haircut.</p> <p>For all of these reasons, when you’re planning to heat treat your hair, protection is a good idea.</p> <h2>How hair protectants work</h2> <p>When you spray on a hair protectant, many possible key ingredients can go to work.</p> <p>They can have <a href="https://library.scconline.org/v062n01/15">daunting-looking names</a> like polyvinyl pyrrolidone, methacrylates, polyquaterniums, silicones and more.</p> <p>These materials are chosen because they readily stick onto your hair, creating a coating, a bit like this:</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/615002/original/file-20240822-16-beyt90.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/615002/original/file-20240822-16-beyt90.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/615002/original/file-20240822-16-beyt90.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=225&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/615002/original/file-20240822-16-beyt90.jpg?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=225&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/615002/original/file-20240822-16-beyt90.jpg?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=225&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/615002/original/file-20240822-16-beyt90.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=283&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/615002/original/file-20240822-16-beyt90.jpg?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=283&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/615002/original/file-20240822-16-beyt90.jpg?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=283&amp;fit=crop&amp;dpr=3 2262w" alt="A cartoon of coating attached to a strand of hair." /></a><figcaption><span class="caption">Hair protectant applies a coating to your hair.</span> <span class="attribution">Author provided</span></figcaption></figure> <p>This coating is a protective layer;

Antarctic heat, wild Australian winter: what’s happening to the weather and what it means for the rest of the year

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/martin-jucker-379172">Martin Jucker</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a></em></p> <p>Australia’s south and east have seen <a href="https://theconversation.com/southern-australia-is-freezing-how-can-it-be-so-cold-in-a-warming-climate-233977">freezing temperatures</a> and <a href="https://www.theguardian.com/australia-news/article/2024/jul/29/australia-winter-weather-forecast-east-coast-colder-records">wild weather</a> this winter. At the same time, the continent as a whole – and the globe – have <a href="https://www.abc.net.au/news/2024-08-03/australia-suffers-cold-winter-weather-despite-mild-forecast/104176284">continued to warm</a>.</p> <p>What’s going on? As ever, it’s hard to pinpoint a single cause for weather events. But a key player is likely an event unfolding high above Antarctica, which itself may have been triggered by a heatwave at surface level on the frozen continent.</p> <p>Here’s what’s happening – and what it might mean for the rest of this year’s weather.</p> <h2>When the stratosphere heats up</h2> <p>Out story begins in the cold air over Antarctica. July temperatures in the stratosphere, the layer of air stretching between altitudes of around 10 and 50 kilometres, are typically around –80°C.</p> <p>The winds are also very strong, averaging about 300 kilometres per hour in winter. These cold, fast winds loop around above the pole in what is called the <a href="https://sites.krieger.jhu.edu/waugh/research/polarvortex">stratospheric polar vortex</a>.</p> <p>Occasionally, persistent high air pressure in the lower atmosphere can influence large-scale waves that extend around the globe and up into the stratosphere. There they cause the strong winds to slow down, and the air high above the pole to become much warmer than normal.</p> <p>In extreme situations the stratospheric winds can completely break down, in what is called a “sudden stratospheric warming” event. These events occur every few years in the northern hemisphere, but only one has ever been observed in the south, in 2002 (though another <a href="https://theconversation.com/the-air-above-antarctica-is-suddenly-getting-warmer-heres-what-it-means-for-australia-123080">almost happened in 2019</a>).</p> <h2>Pushing polar weather our way</h2> <p>Once the polar vortex is disturbed, it can in turn influence the weather at the surface by steering weather systems from the Southern Ocean towards the Equator. However, this is a slow process.</p> <p>The impact at the surface may not be felt until <a href="https://doi.org/10.1175/JCLI-D-22-0425.1">a few weeks or even months</a> after the initial weakening of the stratospheric polar vortex. Once it begins, the stratospheric influence can prevail for more weeks or months, and helps meteorologists make <a href="https://doi.org/10.5194/acp-22-2601-2022">long-range weather forecasts</a>.</p> <p>In climate science terms, the weak stratospheric winds put an atmospheric system called the <a href="http://www.bom.gov.au/climate/sam/">Southern Annular Mode</a> into a negative phase. The main effect of this on surface weather is to bring westerly winds further north.</p> <p>In winter, this means polar air outbreaks can reach places like Sydney more easily. As a result, we see more <a href="https://doi.org/10.1175/JCLI4134.1">rain over much of southern Australia</a>, and snowfall in alpine regions. In spring and summer it means westerly winds blow over the continent before reaching the east coast, bringing warm and dry air to southeastern Australia.</p> <p>The exact impact of a weaker polar vortex depends on how much and for how long the weather systems are being pushed further northward. It will also depend on other weather influencers such as El Niño and the Indian Ocean Dipole.</p> <h1>This winter’s weirdness</h1> <p>Unpicking exactly why any weather event occurs is tricky at the moment, because global weather has been absolutely crazy over the past 12 months or so. Global temperatures are <a href="https://theconversation.com/we-just-blew-past-1-5-degrees-game-over-on-climate-not-yet-213364">much higher than usual</a>, which is making unusual weather very common.</p> <p>But there are indications that the stratosphere is having some influence on our weather this winter.</p> <p>The stratospheric polar vortex started to warm in mid-July, and is about 20°C warmer than the long-term average. At the time of writing, the winds slowed down to about 230 kilometres per hour, 70 kilometres per hour slower than average.</p> <p>These numbers mean that, technically, the event does not qualify as a sudden stratospheric warming. However, further warming may still occur.</p> <p>If we look at how southern hemisphere winds have evolved in the past few weeks, we see a pattern which looks like what we would expect from a sudden stratospheric warming.</p> <p>First, we see warming in the stratosphere which is <a href="https://doi.org/10.1029/2021GL095270">at first accompanied by a poleward shift of weather systems</a>.</p> <p>The stratosphere’s influence then propagates downward and seems to <a href="https://doi.org/10.1175/JCLI-D-22-0425.1">induce many weeks</a> of weather systems shifted towards the equator.</p> <p>This coincides with the period of cold and rainy weather along Australia’s east coast in late July and the beginning of August. Forecasts suggest the Southern Annular Mode will be a long way from normal conditions in the first half of August – four standard deviations below average, which is extremely rare.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/611211/original/file-20240804-19-sp862a.png?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/611211/original/file-20240804-19-sp862a.png?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/611211/original/file-20240804-19-sp862a.png?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=300&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/611211/original/file-20240804-19-sp862a.png?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=300&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/611211/original/file-20240804-19-sp862a.png?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=300&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/611211/original/file-20240804-19-sp862a.png?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=377&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/611211/original/file-20240804-19-sp862a.png?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=377&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/611211/original/file-20240804-19-sp862a.png?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=377&amp;fit=crop&amp;dpr=3 2262w" alt="Diagram showing atmospheric warming and winds" /></a><figcaption><span class="caption">How initial warming high in the stratosphere ends up changing winds near the surface and pushing polar weather further north.</span> <span class="attribution"><a class="source" href="https://stratobserve.com">Z.D.

Why doesn’t water help with spicy food? What about milk or beer?

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/daniel-eldridge-1494633">Daniel Eldridge</a>, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a></em></p> <p>Spicy foods taste spicy because they contain a family of compounds called capsaicinoids. Capsaicin is the major culprit. It’s found in chillies, jalapeños, cayenne pepper, and is even the active ingredient in <a href="https://pubmed.ncbi.nlm.nih.gov/31334983/">pepper spray</a>.</p> <p>Capsaicin doesn’t actually physically heat up your mouth. The burning sensation comes from receptors in the mouth reacting to capsaicin and sending a signal to the brain that something is very hot.</p> <p>That’s why the “hot” chilli sensation feels so real – we even respond by sweating. To alleviate the heat, you need to remove the capsaicin from your mouth.</p> <p>So why doesn’t drinking water help make that spicy feeling go away? And what would work better instead?</p> <h2>Water-loving and water-hating molecules</h2> <p>To help us choose what might wash the capsaicin away most effectively, it’s helpful to know that capsaicin is a hydrophobic molecule. That means it hates being in contact with water and will not easily mix with it.</p> <p>Look what happens when you try to mix hydrophobic sand with water.</p> <figure><iframe src="https://www.youtube.com/embed/H8cj9CpHW7w?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>On the other hand, hydrophilic molecules love water and are very happy to mix with it.</p> <p>You’ve likely seen this before. You can easily dissolve hydrophilic sugar in water, but it’s hard to wash away hydrophobic oils from your pan using tap water alone.</p> <p>If you try to wash hydrophobic capsaicin away with water, it won’t be very effective, because hydrophilic and hydrophobic substances don’t mix.</p> <p>Going for iced water will be even less effective, as hydrophobic capsaicin is even less soluble in water at lower temperatures. You may get a temporary sense of relief while the cold liquid is in your mouth, but as soon as you swallow it, you’ll be back where you started.</p> <p>Instead, a good choice would be to consume something that is also hydrophobic. This is because of an old-but-true adage in chemistry that “like dissolves like”.</p> <p>The idea is that generally, hydrophobic substances will not dissolve in something hydrophilic – like water – but will dissolve in something that is also hydrophobic, as this video shows:</p> <figure><iframe src="https://www.youtube.com/embed/s5yfs-Pr_y8?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <h2>My mouth is on fire. What should I drink instead of water?</h2> <p>A swig of oil would likely be effective, but is perhaps not so palatable.</p> <p>Milk makes for an ideal choice for two reasons.</p> <p>The first is that milk contains hydrophobic fats, which the capsaicin will more easily dissolve in, allowing it to be washed away.</p> <p>The second is that dairy products contain a protein called casein. Casein is an emulsifier, a substance that helps oils and water mix, as in this video:</p> <figure><iframe src="https://www.youtube.com/embed/S4XeQhZRLDE?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>Casein plays a large role in keeping the fat mixed throughout your glass of milk, and it also has a strong affinity for capsaicin. It will readily wrap up and encapsulate capsaicin molecules and assist in carrying them away from the receptor. This relieves the <a href="https://pubmed.ncbi.nlm.nih.gov/36510373/">burning sensation</a>.</p> <h2>OK but I hate drinking milk. What else can I try?</h2> <p>What about raita? This dish, commonly served with Indian curries, is made primarily from yoghurt. So aside from being its own culinary experience, raita is rich in fats, and therefore contains plenty of hydrophobic material. It also contains casein, which will again help lock up and remove the capsaicin.</p> <p>Ice cream would also work, as it contains both casein and large amounts of hydrophobic substances.</p> <p>Some studies have also shown that consuming <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9328490/">drinks with large amounts of sugar</a> can relieve spiciness.</p> <p>What about reaching for that ice cold beer?</p> <p>This is commonly suggested as a suitable approach to stop the burning. At first glance, this may seem a good idea because capsaicin is highly soluble in alcohol.</p> <p>However, most beers only contain between 4–6% alcohol. The bulk of the liquid in beer is water, which is hydrophilic and cannot wash away capsaicin. The small amount of alcohol in your beer would make it slightly more effective, but not to any great degree.</p> <p>Your curry and beer may taste great together, but that’s likely the only benefit.</p> <p>In truth, an alcoholic beverage is not going to help much unless you go for something with a much, much higher alcohol content, which comes with its own problems.<!-- Below is The Conversation's page counter tag.

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

<p><em><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></em></p> <p>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.</p> <p>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.</p> <p>Heat illnesses can vary, from relatively mild heat exhaustion to the potentially life-threatening condition of heat stroke.</p> <h2>What are the signs and symptoms?</h2> <p>If you’re suffering from heat exhaustion, you may feel weakness, nausea, headaches or dizziness.</p> <p>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.</p> <p>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.</p> <p>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.</p> <p>When it comes to cooling someone with suspected heat stroke, the quicker the better: cool first, transport second.</p> <h2>Why do we overheat?</h2> <p>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.</p> <p>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.</p> <p>Sweating is by far our most effective physiological means of keeping cool. However, it is the <em>evaporation</em> of sweat from our skin that provides cooling relief.</p> <p>When the air is humid, it already contains a lot of moisture, and this reduces how efficiently sweat evaporates.</p> <p>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.</p> <p>Finally, clothing can act as an insulator and barrier for the evaporation of sweat, making it even more difficult for us to keep cool.</p> <h2>Who is most vulnerable in the heat?</h2> <p>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.</p> <p>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.</p> <p>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>.</p> <p>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.</p> <p>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.</p> <p>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.</p> <p>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.</p> <h2>How to stay safe in the heat</h2> <p>Thankfully, there are effective, low-cost <a href="https://twitter.com/TheLancet/status/1677702906789740545">ways</a> of staying safe in the heat.

Heated argument between economy passengers reignites plane etiquette debate

<p>A 12-second clip of two passengers arguing on a plane has reignited the age-old debate of whether it is acceptable to recline your seat on a plane. </p> <p>The viral video which was originally posted on TikTok and then re-shared on X, has racked up over 8 million views since Thursday. </p> <p>In the video, a frustrated woman was calling out another female passenger for pushing her seat the entire flight, right after they landed. </p> <p>“The whole trip she pushed my seat,” the woman said to a male passenger seated next to the female passenger accused of kicking her seat. </p> <p>“You seen it. You know she did.”</p> <p>“I’m allowed to put my seat back," she yelled repeatedly. </p> <p>Ian Miles Cheong, the user who posted the video on X, defended the woman saying: “She’s allowed to put her seat back. You don’t get to kick it repeatedly just because you want more space.”</p> <p>A few were on the woman's side and praised her for standing up for herself. </p> <p>“You are allowed! Period! You want space in front of you instead of pushing the seat, buy a seat with extra space or get your a** to business class. Reclining was put there for a reason,” one person wrote. </p> <p>“She was patient enough to wait till flight landed," they added. </p> <p>“If the seat is reclinable, recline it,” another commented. </p> <p>"What she’s saying is right. The woman has a right to put her seat back without someone kicking it," a third agreed.</p> <blockquote class="twitter-tweet"> <p dir="ltr" lang="en">She’s allowed to put her seat back. You don’t get to kick it repeatedly just because you want more space. <a href="https://t.co/WELD7Qh4Re">pic.twitter.com/WELD7Qh4Re</a></p> <p>— Ian Miles Cheong (@stillgray) <a href="https://twitter.com/stillgray/status/1719881310351863952?ref_src=twsrc%5Etfw">November 2, 2023</a></p></blockquote> <p>However, others claimed that there was an unwritten rule that you shouldn't recline your seat, especially on a short-haul flight, adding that the recline feature should be scrapped from airplanes. </p> <p>“Putting your seat back in coach is an unspoken thing most people don’t do. It’s really the airline’s fault because they’ve made coach so cramped and tight that putting the seat back shouldn’t even be an option,” one commented. </p> <p>“Airline seats simply shouldn’t be able to recline. It intrudes on the already very little space a person has on the plane for the person behind them,” another added. </p> <p>“Really it’s the airline’s fault for cramming so many people in such a small space. They don’t call it cattle class for nothing,” a third wrote. </p> <p>One user understood both sides of the argument, and blamed the airlines for making the seats so cramped. </p> <p>"It can be annoying sometimes to be behind someone with their seat all the way, but if the airlines didn't want to allow that, it wouldn't happen," they wrote.</p> <p>"You don't kick the seat like a baby. Blame the airline, not the person doing what the airline says is fine." </p> <p><em>Images: Twitter</em></p>

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.</p> <p>A person with dementia can also wander and become lost, which can be dangerous in extreme heat.</p> <h2>4 ways to support someone with dementia</h2> <p><strong>1. Avoid dehydration and heatstroke</strong></p> <p>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>.</p> <p>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.</p> <p>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.</p> <p><strong>2. Cool the home</strong></p> <p>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.</p> <p>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.</p> <p>Try to support the person to make suitable clothing choices for the season by having cool, lightweight options easily available.</p> <p><strong>3. Think about communications early</strong></p> <p>If someone with dementia lives alone, consider how you will maintain contact in an emergency.</p> <p>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.</p> <p><strong>4. Have an evacuation plan</strong></p> <p>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.</p> <p>The situation can change quickly in an emergency, and this can be particularly overwhelming for people with cognitive issues.</p> <p>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.</p> <p>Stay up-to-date with <a href="http://www.bom.gov.au/">current warnings</a> and act early whenever possible.</p> <h2>We can all help</h2> <p>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.</p> <p>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" /></p> <p><a href="https://theconversation.com/profiles/nikki-anne-wilson-342631"><em>Nikki-Anne Wilson</em></a><em>, Postdoctoral Research Fellow, Neuroscience Research Australia (NeuRA), <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a></em></p> <p><em>Image credits: Getty Images</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

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

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

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

<p><em><a href="https://theconversation.com/profiles/nial-wheate-96839">Nial Wheate</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> and <a href="https://theconversation.com/profiles/tina-hinton-329706">Tina Hinton</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>The daily use of <a href="https://www.nps.org.au/australian-prescriber/articles/drugs-in-secondary-stroke-prevention">low dose aspirin</a> has been a mainstay of preventing strokes for decades. While there has always been a risk of bleeding associated with aspirin use, the benefits were thought to outweigh the risk.</p> <p>Now <a href="https://dx.doi.org/10.1001/jamanetworkopen.2023.25803">new research</a> led by Monash University has shown daily, low-dose aspirin doesn’t prevent strokes in relatively healthy people aged over 70. And it increases their risk of bleeding on the brain after falls or other injuries.</p> <p>But if you’re taking aspirin, it doesn’t mean you should abruptly stop. It may still have a role to play in treating people at high risk of stroke. Or, after talking to your doctor, there might be better options available.</p> <h2>Why has aspirin been used to prevent strokes?</h2> <p>Aspirin is an anti-platelet medicine, which is commonly known as a blood-thinner. <a href="https://www.lifeblood.com.au/blood/learn-about-blood/platelets">Platelets</a> are the component of blood primarily responsible for its clotting action. They are what stop you from continuously bleeding any time you have a cut or scrape on your skin.</p> <p>A <a href="https://strokefoundation.org.au/about-stroke/learn/what-is-a-stroke">stroke</a> is when oxygen can’t get into the brain because of a burst or blocked blood vessel. A blockage can occur when platelets in the bloodstream form a clot and it gets stuck in the artery.</p> <p>Because aspirin acts on platelets, it can help prevent the clots that can lead to a stroke.</p> <p>But because aspirin acts on platelets, it can also increase the risk of <a href="https://www.mayoclinic.org/diseases-conditions/heart-disease/in-depth/daily-aspirin-therapy/art-20046797#:%7E:text=While%20daily%20aspirin%20can%20help,of%20developing%20a%20stomach%20ulcer.">unwanted bleeding</a>, usually in the stomach. It can also increase your risk of bleeding more when you have another injury, like hitting your head.</p> <p>Aspirin isn’t just used for the prevention of strokes. It is also the first aid treatment for someone undergoing a <a href="https://www.nps.org.au/australian-prescriber/articles/acute-myocardial-infarction-early-treatment">heart attack</a>.</p> <h2>Findings of the Monash trial</h2> <p>New <a href="https://dx.doi.org/10.1001/jamanetworkopen.2023.25803">research from Australia and the United States</a> reports results from the Aspirin in Reducing Events in the Elderly (ASPREE) trial.</p> <p>The researchers examined the protective use of daily low-dose aspirin (100 mg) in nearly 2,000 people who were aged 70 years and older and had no history of heart disease or stroke and whose blood pressure and cholesterol were well managed.</p> <p>When compared with placebo, aspirin didn’t reduce or increase the risk of stroke. Of the participants who took the aspirin, 195 or 4.6% had a stroke. Of those who took the placebo, 203 people or 4.7% had a stroke.</p> <p>But it did statistically increase the rate of non-stroke bleeding in the participants’ brains, for example when they injured their head. Those on aspirin showed a rate of bleeding in the brain of 1.1% (108 participants) compared with 0.8% (79 people) for those on placebo. This is a relatively, low but serious, risk.</p> <p>These findings are not entirely new. <a href="https://www.nejm.org/doi/full/10.1056/NEJMoa1800722?query=featured_home">Research</a> published five years ago based on the same ASPREE trial showed a similar result: a higher rate of bleeding among those taking low-dose aspirin compared with placebo.</p> <p>However as the study authors note, aspirin continues to be widely used for the prevention of stroke.</p> <h2>What are the study’s limitations?</h2> <p>The researchers examined aspirin in mostly people of white European heritage.</p> <p>So we don’t know whether the results are translatable to people with different ethnic backgrounds. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2594139/">Genetics and ethnicity</a> can significantly impact the efficacy and safety of some drugs.</p> <p>The clinical trial only included people who were not significantly at risk of a stroke, and had no history of heart disease.</p> <p>Younger age groups were not studied either, so we cannot make any conclusions about their use of low dose aspirin to prevent stroke.</p> <p>It’s also possible the potential benefits and risks are different for those who have underlying heart problems or who have previously had a stroke and are therefore at higher risk of another stroke.</p> <h2>I’m taking aspirin, what should I do?</h2> <p>If you’re taking daily low-dose aspirin and are concerned by the results of the study, it’s important you don’t just stop taking your medicine. Speak to your doctor or pharmacist.</p> <p>For people who are at high risk of having a stroke, or have previously had one, low-dose aspirin may remain their treatment of choice despite the slight bleeding risk.</p> <p>If you’re at high risk of bleeding, for example because of falls and other accidents due to advanced age, frailty, or another underlying condition, your doctor may be able to reduce the amount of aspirin you take by adding in <a href="https://www.nps.org.au/australian-prescriber/articles/dipyridamole">dipyridamole</a> or prescribing a different medicine completely, such as <a href="https://www.nps.org.au/australian-prescriber/articles/clopidogrel">clopidogrel</a>.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/210388/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/nial-wheate-96839">Nial Wheate</a>, Associate Professor of the Sydney Pharmacy School, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> and <a href="https://theconversation.com/profiles/tina-hinton-329706">Tina Hinton</a>, Associate Professor of Pharmacology, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p><em>Image credits: Getty </em><em>Images </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Tourists flock to the Mediterranean as if the climate crisis isn’t happening. This year’s heat and fire will force change

<p><em><a href="https://theconversation.com/profiles/susanne-becken-90437">Susanne Becken</a>, <a href="https://theconversation.com/institutions/griffith-university-828">Griffith University</a> and <a href="https://theconversation.com/profiles/johanna-loehr-1457342">Johanna Loehr</a>, <a href="https://theconversation.com/institutions/griffith-university-828">Griffith University</a></em></p> <p>Thousands of people on the beach. Children reportedly falling off evacuation boats. Panic. People fleeing with the clothes on their backs. It felt like “the end of the world”, according to <a href="https://www.theguardian.com/world/2023/jul/23/british-tourists-tell-of-nightmare-in-rhodes-fires-greece">one tourist</a>.</p> <p>The fires sweeping through the Greek islands of Rhodes and Corfu are showing us favourite holiday destinations are no longer safe as climate change intensifies.</p> <p>For decades, tourists have flocked to the Mediterranean for the northern summer. Australians, Scandinavians, Brits, Russians all arrive seeking warmer weather. After COVID, many of us have been keen to travel once again.</p> <p>But this year, the intense heatwaves have claimed <a href="https://inews.co.uk/news/world/heatwave-pictures-wildfires-worsen-greece-italy-spain-europe-us-2488556">hundreds of lives</a> in Spain alone. Major tourist drawcards such as the Acropolis in Athens have been closed. Climate scientists are “stunned by the ferocity” of the <a href="https://www.theguardian.com/commentisfree/2023/jul/25/northern-hemisphere-heatwaves-europe-greece-italy-wildfires-extreme-weather-climate-experts">heat</a>.</p> <p>This year is likely to force a rethink for tourists and for tourism operators. Expect to see more trips taken during shoulder seasons, avoiding the increasingly intense July to August summer. And expect temperate countries to become more popular tourist destinations. Warm-weather tourist destinations will have to radically change.</p> <h2>What will climate change do to mass tourism?</h2> <p>Weather is a major factor in tourism. In Europe and North America, people tend to go from northern countries to southern regions. Chinese tourists, like Australians, often head to Southeast Asian beaches.</p> <p>In Europe, the north-south flow is almost hardwired. When Australians go overseas, they often choose Mediterranean summers. Over the last decade, hotter summers haven’t been a dealbreaker.</p> <p>But this year is likely to drive change. You can already see that in the growing popularity of shoulder seasons (June or September) in the traditional Northern Hemisphere summer destinations.</p> <p>Many of us are shifting how we think about hot weather holidays from something we seek to something we fear. This comes on top of consumer shifts such as those related to sustainability and <a href="https://theconversation.com/flight-shaming-how-to-spread-the-campaign-that-made-swedes-give-up-flying-for-good-133842">flight shame</a>.</p> <p>What about disaster tourism? While thrillseekers <a href="https://www.theguardian.com/us-news/2023/jul/22/death-valley-tourism-extreme-weather-california">may be flocking</a> to Death Valley to experience temperatures over 50℃, it’s hard to imagine this type of tourism going mainstream.</p> <p>What we’re more likely to see is more people seeking “<a href="https://www.tandfonline.com/doi/abs/10.1080/09669582.2016.1213849?journalCode=rsus20">last-chance</a>” experiences, with tourists flocking to highly vulnerable sites such as the Great Barrier Reef. Of course, this type of tourism isn’t sustainable long-term.</p> <h2>What does this mean for countries reliant on tourism?</h2> <p>The crisis in Rhodes shows us the perils of the just-in-time model of tourism, where you bring in tourists and everything they need –food, water, wine – as they need it.</p> <p>The system is geared to efficiency. But that means there’s little space for contingencies. Rhodes wasn’t able to easily evacuate 19,000 tourists. This approach will have to change to a just-in-case approach, as in other <a href="https://www.forbes.com/sites/willyshih/2022/01/30/from-just-in-time-to-just-in-case-is-excess-and-obsolete-next/?sh=195cd054daf7">supply chains</a>.</p> <p>For <a href="https://www.sciencedirect.com/science/article/abs/pii/S0261517712002063">emergency services</a>, tourists pose a particular challenge. Locals have a better understanding than tourists of risks and escape routes. Plus tourists don’t speak the language. That makes them much harder to help compared to locals.</p> <p>Climate change poses immense challenges in other ways, too. Pacific atoll nations like Kiribati or Tuvalu <a href="https://www.pacificpsdi.org/assets/Uploads/PSDI-TourismSnapshot-TUV3.pdf">would love</a> more tourists to visit. The problem there is water. Sourcing enough water for locals is getting harder. And tourists use a lot of water – drinking it, showering in it, swimming in it. Careful planning will be required to ensure local carrying capacities are not exceeded by tourism.</p> <p>So does this spell the end of mass tourism? Not entirely. But it will certainly accelerate the trend in countries like Spain away from mass tourism, or “overtourism”. In super-popular tourist destinations like Spain’s Balearic Islands, there’s been an increasing pushback from locals against <a href="https://theconversation.com/were-in-the-era-of-overtourism-but-there-is-a-more-sustainable-way-forward-108906">overtourism</a> in favour of specialised tourism with smaller numbers spread out over the year.</p> <p>Is this year a wake-up call? Yes. The intensifying climate crisis means many of us are now more focused on what we can do to stave off the worst of it by, say, avoiding flights. The pressure for change is growing too. Delta Airlines is being sued over its announcement to go carbon neutral by <a href="https://www.theguardian.com/environment/2023/may/30/delta-air-lines-lawsuit-carbon-neutrality-aoe">using offsets</a>, for instance.</p> <h2>Mountains not beaches: future tourism may look a lot different</h2> <p>You can already see efforts to adapt to the changes in many countries. In Italy, for instance, domestic mountain tourism is <a href="https://www.euromontana.org/en/neve-diversa-how-mountain-tourism-can-adapt-to-climate-change/">growing</a>, enticing people from hot and humid Milan and Rome up where the air is cooler – even if the snow is disappearing.</p> <p>China, which doesn’t do things by halves, is investing in mountain resorts. The goal here is to offer cooler alternatives like northern China’s <a href="https://english.news.cn/20230714/9ae6f89a6b7b433ebde3ec689b87f6db/c.html">Jilin province</a> to beach holidays for sweltering residents of megacities such as Beijing and Shanghai.</p> <p>Some mountainous countries are unlikely to seize the opportunity because they don’t want to draw more tourists. Norway is considering a <a href="https://www.forbes.com/sites/davidnikel/2022/12/03/norway-to-consider-introducing-tourist-tax-from-2024/?sh=710871eb1b27">tourist tax</a>.</p> <p>Forward-thinking countries will be better prepared. But there are limits to preparation and adaptation. Mediterranean summer holidays will be less and less appealing, as the region is a <a href="https://www.unep.org/unepmap/resources/factsheets/climate-change">heating hotspot</a>, warming 20% faster than the world average. Italy and Spain are still <a href="https://joint-research-centre.ec.europa.eu/jrc-news-and-updates/severe-drought-western-mediterranean-faces-low-river-flows-and-crop-yields-earlier-ever-2023-06-13_en">in the grip</a> of a record-breaking drought, threatening food and water supplies.

"What a FIGHTER!": Susan Boyle reveals secret health scare during comeback

<p>Singing sensation Susan Boyle surprised her fans with an unexpected appearance on<em> Britain’s Got Talent </em>for the competition’s extravagant final. </p> <p>Boyle, who had previously appeared on the show herself in 2009, took to the stage with the cast of the West End’s <em>Les Miserables</em> for a performance of the song ‘I Dreamed a Dream’ - the same one she auditioned with when she was a competitor. </p> <p>And fans were treated to one more song, with the ensemble joining Boyle for a rendition of ‘Do You Hear The People Sing?’ too. </p> <p>Once the crowd’s delighted applause had quietened, Britain’s Got Talent hosts Ant and Dec approached Boyle, gushing over her as they welcomed her back to the stage. </p> <p>“It is so lovely to see you,” Dec declared. “It’s hard to believe you appeared on this show in 2009 - fourteen years ago. How does it feel to be back at <em>BGT</em>?” </p> <p>“It feels great,” Susan told him, to further cheering from the audience. </p> <p>She went on to share that the whole affair was “extra special” to her, before revealing that “last April there, I suffered a minor stroke.”</p> <p>The theatre was quiet, everyone taken by surprise, before Boyle announced that she’d “fought like crazy to get back on stage, and I have done it.”</p> <p>As Dec shared that they were “thrilled” to hear of her triumphant return, cheers rang out once again, and applause echoed throughout the room in celebration of Boyle. </p> <p>When judge Simon Cowell - who was present for Boyle’s audition as well - was asked how it felt to see her back on the stage, he noted that it was “unbelievable”. </p> <p>“Susan, we owe you so much,” he said, “and I knew you weren't well, but if anyone was going to come back, you were going to come back, because we wouldn't be the same without you. You are amazing."</p> <p>And when clips from her performance, and following reveal, made it online, fans wasted no time in sharing their love and support for the singer. </p> <p>“Huge huge respect for Susan Boyle,” one wrote. “Post stroke and absolutely smashing it on BGT tonight! Incredible!”</p> <p>“Good for her! Great to see her back!” another said. “Never ever be defined by an illness or disability. Never.”</p> <p>“Aww! Susan Boyle is an absolute superstar in every sense of the word, so humble,” one gushed. “It’s so good to see her back with her microphone!”</p> <p>And as someone else put it, “bless Susan Boyle, she spent her entire life not realising her full potential as a West End singer, to then go on to be one of the biggest stars to come out of #BGT. Her performance tonight had passion; she has real HEART and her having a stroke last year - what a FIGHTER!”</p> <blockquote class="twitter-tweet"> <p dir="ltr" lang="en">⭐ STAGEY SMILE OF THE DAY ⭐</p> <p>Here's Lucie Jones &amp; Susan Boyle performing "I Dreamed A Dream" from Les Misérables, for the BGT grand final 🇫🇷 ✨ X x x <a href="https://t.co/nmIB5eo29c">pic.twitter.com/nmIB5eo29c</a></p> <p>— Theatre Fan (@ShaunTossell) <a href="https://twitter.com/ShaunTossell/status/1665467122053443586?ref_src=twsrc%5Etfw">June 4, 2023</a></p></blockquote> <p><em>Images: Twitter</em></p>

How to keep your pets cool in the heat

<p>Now that the weather is warm, extra precautions in the sun are necessary not just for yourself, but for your furry companion. Try these useful tips to help keep Fido and Fluffy safe and cool in the heat all summer long.</p> <p><strong>Give them a trim –</strong> If your pet has long hair, consider grooming them seasonally, as shorter hair makes a big difference in their overall temperature.</p> <p><strong>Keep water handy –</strong> If you leave the house with your pet, always be sure to have water on you as well as a receptacle from which they can drink to keep your pet cool and hydrated. You can even set up a kiddy pool in your backyard for your dog to play in.</p> <p><strong>Look for shade –</strong> If you’re out with your dog midday, try to avoid direct sunlight by locating a shady area for a rest.</p> <p><strong>Follow their lead –</strong> If you dog or cat seems most content to stay indoors and enjoy the air conditioning, let them. They can tell if it’s too hot outside for them.</p> <p><strong>Time it right –</strong> Avoid going out midday when possible, and take your dog for walks during the mornings and evenings instead.</p> <p><strong>Never leave them in the car –</strong> Many animals die every year because irresponsible owners leave them in a car, leading to over-heating. Even if the day seems moderate in temperature, a car can still heat up drastically due to solar heat beaming in through the windows. If you’ll be leaving your car alone, leave your pet at home.</p> <p><strong>Act according to breed –</strong> If your pet has a flat-shaped face, such as a pug or Persian cat, they are especially susceptible to the heat as they are unable to cool down through panting as effectively as other breeds can. If in doubt, bring them inside where it is cooler.</p> <p><em>Image credit: Shutterstock</em></p>

"It was a loud wake-up call": Aaron Sorkin's serious health scare

<p dir="ltr">Award-winning screenwriter and director Aaron Sorkin has revealed he suffered a stroke last November.</p> <p dir="ltr">In an interview with <em>The New York Times</em>, the 61-year-old, who holds three Golden Globes and five Emmys, said the experience was so intense it made him think he might never work again.</p> <p dir="ltr">"There was a minute when I was concerned that I was never going to be able to write again," Sorkin said.</p> <p dir="ltr">Sorkin revealed that the stroke occurred two months before rehearsals for his upcoming musical – a re-written version of <em>Camelot</em>.</p> <p dir="ltr">The <em>West Wing</em> creator said that the symptoms showed up in the middle of the night when he realised that he kept crashing into walls on his way to the kitchen.</p> <p dir="ltr">The symptoms carried on the next day, when he found himself continually spilling a glass of orange juice in his home office.</p> <p dir="ltr">When he went to the doctors they said his blood pressure was so high, he was "supposed to be dead".</p> <p dir="ltr">Sorkin also shared that he’s still suffering from the side effects as he hasn’t been able to taste food properly since the stroke.</p> <p dir="ltr">A month after the stroke, Sorkin struggled to type and was slurring his words, it’s only recently that he finally built up the coordination to be able to sign his name again.</p> <p dir="ltr">The director shared that the stroke has led him to make some major lifestyle changes.</p> <p dir="ltr">"Mostly it was a loud wake-up call," he said. "I thought I was one of those people who could eat whatever he wanted, smoke as much as he wanted, and it's not going to affect me. Boy, was I wrong," he said.</p> <p dir="ltr">Sorkin has since given up smoking, works out twice a day and has incorporated a healthier diet. "I take a lot of medicine. You can hear the pills rattling around in me," he added.</p> <p dir="ltr">The screenwriter is currently preparing for the opening of his new musical, <em>Camelot</em>, which is his fourth Broadway production.</p> <p><em>Image: Getty Images</em></p>

Is my medicine making me feel hotter this summer? 5 reasons why

<p>If you’re really feeling the heat this summer, it might be down to more than the temperature outside.</p> <p>Some types of medicines can increase your core body temperature or make you feel hotter than you really are. Some can affect your body’s ability to cool down.</p> <p>Here’s what you need to know about heat intolerance and medicines.</p> <h2>What is heat intolerance?</h2> <p>Some people simply dislike the feeling of feeling hot, while others feel hot at temperatures most people find comfortable. Both are examples of <a href="https://www.medicalnewstoday.com/articles/325232#symptoms">heat intolerance</a>.</p> <p>Typical symptoms during warm weather include excessive sweating (or not sweating enough), exhaustion and fatigue, nausea, vomiting or dizziness, and changes in mood.</p> <p>A number of factors can cause heat intolerance.</p> <p>This includes the disorder <a href="https://my.clevelandclinic.org/health/diseases/6004-dysautonomia">dysautonomia</a>, which affects people’s autonomic nervous system – the part of the body that regulates the automatic functions of the body, including our response to heat. </p> <p>Conditions such as diabetes, alcohol misuse, <a href="https://theconversation.com/what-causes-parkinsons-disease-what-we-know-dont-know-and-suspect-57579">Parkinson’s disease</a>, the autoimmune disease <a href="https://theconversation.com/explainer-what-is-guillain-barre-syndrome-and-is-it-caused-by-the-zika-virus-53884">Guillain-Barré syndrome</a> and <a href="https://theconversation.com/explainer-what-are-mitochondria-and-how-did-we-come-to-have-them-83106">mitochondrial disease</a> can cause dysautonomia. People in old age, those with some neurological conditions, or people less physically fit may also have it.</p> <p>But importantly, medications can also contribute to heat intolerance.</p> <h2>1. Your body temperature rises</h2> <p>Some medicines directly increase your body temperature, which then increases the risk of heat intolerance. </p> <p>These include <a href="https://bpspubs.onlinelibrary.wiley.com/doi/epdf/10.1111/bph.15465">stimulant medications</a> to treat ADHD (attention deficit hyperactivity disorder), such as methylphenidate, dexamfetamine and lisdexamfetamine.</p> <p><a href="https://www.healthdirect.gov.au/antipsychotic-medications">Antipsychotic medications</a> (such as clozapine, olanzapine and quetiapine) used to treat mental health conditions, such as schizophrenia and bipolar disorder, are other examples. </p> <p>These ADHD and antipsychotic medicines raise your temperature by acting on the hypothalamus, the region of the brain essential for cooling.</p> <p>The drug levothyroxine, used to treat an under-active thyroid, also increases your body temperature, this time by <a href="https://www.ncbi.nlm.nih.gov/books/NBK500006/">increasing your metabolism</a>.</p> <h2>2. Your blood flow is affected</h2> <p>Other medicines constrict (tighten) blood vessels, decreasing blood flow to the skin, and so prevent heat from escaping this way. This means your body can’t regulate its temperature as well in the heat. </p> <p>Examples include <a href="https://www.healthdirect.gov.au/beta-blockers">beta-blockers</a> (such as metoprolol, atenolol and propranolol). These medications are used to treat conditions such as high blood pressure, angina (a type of chest pain), tachycardia (fast heart rate), heart failure, and to prevent migraines. </p> <p><a href="https://www.nhs.uk/conditions/decongestants/">Decongestants</a> for blocked noses (for example, pseudoephedrine and phenylephrine), triptans for migraines (such as sumatriptan and zolmitriptan) and the ADHD medications mentioned earlier can also act to decrease blood flow to the skin.</p> <h2>3. You can get dehydrated</h2> <p>Other medicines can cause dehydration, which then makes you more susceptible to heat intolerance. The best examples are <a href="https://www.mayoclinic.org/diseases-conditions/high-blood-pressure/in-depth/diuretics/art-20048129">diuretics</a> such as furosemide, hydrochlorothiazide, acetazolamide and aldosterone.</p> <p>These are used to control high blood pressure and heart failure by forcing your kidneys to remove more fluid from your body. </p> <p>Laxatives, such as senna extract and bisacodyl, also remove water from your body and so have a similar effect.</p> <h2>4. You can sweat less</h2> <p>Other medicines have a drying effect. This can be needed for medicines to do their job (for instance, to dry up a runny nose). For others, it is an unwanted side effect. </p> <p>This drying reduces the amount you sweat, making it harder to lose heat and regulate your core temperature. A number of medicines have these effects, including:</p> <ul> <li>some antihistamines (such as promethazine, doxylamine and diphenhydramine)</li> <li>certain antidepressants (such as amitriptyline, clomipramine and dothiepin)</li> <li>medicines used to treat <a href="https://www.healthdirect.gov.au/urinary-incontinence#:%7E:text=Urinary%20incontinence%2C%20or%20poor%20bladder%20control%2C%20is%20very%20common%20in,to%20cure%20or%20improve%20it.">urinary incontinence</a> (for example, oxybutynin and solifenacin) </li> <li>nausea medicine (prochlorperazine)</li> <li>medicines for stomach cramps and spasms (for instance, hyoscine) </li> <li>the antipsychoptics chlorpromazine, olanzapine, quetiapine and clozapine.</li> </ul> <h2>5. You don’t feel thirsty</h2> <p>Finally, some medicines, such as the antipsychotics haloperidol and droperidol, can aggravate heat intolerance by reducing your ability to feel thirsty. </p> <p>If you don’t feel thirsty, you drink less and are therefore at risk of dehydration and feeling hot.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://theconversation.com/is-my-medicine-making-me-feel-hotter-this-summer-5-reasons-why-199085" target="_blank" rel="noopener">The Conversation</a>. </em></p>

Stop your makeup melting in the heat

<p>Party season and soaring temperatures mean one thing – melting makeup! Make sure you don’t end up looking like Alice Cooper this summer with our guide to a face that stays put even when the mercury rises.</p> <p><strong>Blank canvas </strong></p> <p>Exfoliate so that your face is ultra-smooth and products will stay on evenly, rather than migrating to one particularly dry area. </p> <p>After your usual moisturizer, make sure you apply SPF30+ or SPF50+ sunscreen. After all, there’s no point in going to all this trouble if you’re just going to end up looking like a tomato anyway! </p> <p>Then use a primer to take away shine. Another layer might seem counter-productive, but you can imagine what happens to make-up that’s applied to a slippery surface.</p> <p><strong>Dare to bare</strong></p> <p>Too much powder and sweat aren’t a good mix, literally. Powders can clog and looked caked when we start to ‘glow’ on scorching days. Similarly, long-lasting foundations can be too heavy and textured and look too much like make-up.</p> <p>Instead, opt for a light coverage foundation or illuminating tinted moisturiser to keep your look sheer and natural. </p> <p><strong>Cheeks </strong></p> <p>Using a brush, apply a cream blush to the apples of your cheeks. The beauty of a cream blush is that if it starts to budge, you can just blend it back in with your finger.</p> <p>Go easy on the bronzer.  Use a shade that’s just one shade darker than your natural skin tone and apply it only where the sun would naturally catch your face. </p> <p><strong>Eye</strong></p> <p>Smokey eyes soon become raccoon eyes in the heat, so keep the natural look going with a creamy, slightly shimmery eye shadow in a coppery shade. Stick-style shadows stay in place very well and are easy to reapply on-the-go. </p> <p>Liquid eyeliner is best avoided in the heat. Use a pencil or at least a waterproof formulation.</p> <p>To avoid your eyebrows melting, go for a light pencil rather than a wax, then finish your eyes with waterproof mascara. </p> <p><strong>Lips</strong></p> <p>Thick gloss can feel a bit gloopy when the temperatures soar, and a heavy lipstick will overwhelm the natural look on your eyes and cheeks. Try a light chubby-stick style lip stain or a tinted lip balm with SPF in it to provide sheer colour and sun protection in one.</p> <p><strong>Staying power</strong></p> <p>It’s really important to ‘set’ your face after you’ve applied it, but it’s a fine line between setting it and adding powder that’s just going to cake.</p> <p>Use a good quality translucent powder just on your T-zone. A little goes a long way so dab it on the back of your hand first, then apply from there.</p> <p>Finally, keep some blotting papers in your handbag. Blotting papers don’t just mattify shine- they actually soak up excess oil and sweat, so they’re perfect for hot days!</p> <p><em>Image credits: Getty Images</em></p>

Europe warming at double the rate of other continents

<p>Europe is the fastest-warming continent in the world, according to a newly released report from the World Meteorological Organization.</p> <p>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.</p> <p>Climate change events were also responsible for more than US$50 billion in damages.</p> <p>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.</p> <p>That rate is twice as high as the next fastest warming continent.</p> <p>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.</p> <p>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.</p> <h2>But are carbon emissions decreasing in Europe?</h2> <p>Fuel prices and the COVID-19 pandemic were major influences on the continent’s carbon emissions reduction, the WMO found.</p> <p>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.</p> <p>2021 also marked the introduction of EU legislation to make net zero by 2050 a legally-binding target for member nations.</p> <p>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.</p> <p>And observers will keenly await the release of next year’s 2022 appraisal, after record summer droughts and heatwaves heaped pressure on European nations.</p> <p>Even now, regions across the continent are recording their hottest temperatures for November on record. </p> <blockquote class="twitter-tweet"> <p dir="ltr" lang="en">(2) More November records in Europe.<br />France had 21 records today (left column), the most important were: Aigues Mortes (POR since 1872), Aix en Provence and Valence (1st class stations).<br />In Austria 4 records beaten the highest was 23.3C at Hohe Wand (right column).<br />tb continued.. <a href="https://t.co/DjmR7oR0oR">pic.twitter.com/DjmR7oR0oR</a></p> <p>— Extreme Temperatures Around The World (@extremetemps) <a href="https://twitter.com/extremetemps/status/1587481854680219653?ref_src=twsrc%5Etfw">November 1, 2022</a></p></blockquote> <p>“[Europe] reminds us that even well-prepared societies are not safe from impacts of extreme weather events,” says WMO secretary-general Professor Petteri Taalas.</p> <p>“This year, like 2021, large parts of Europe have been affected by extensive heatwaves and drought, fuelling wildfires. In 2021, exceptional floods caused death and devastation.</p> <p>“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.”</p> <h2>Future outlook</h2> <p>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.</p> <p>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.</p> <p>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.</p> <p>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.</p> <p><strong>This article originally appeared on <a href="https://cosmosmagazine.com/earth/europe-warming-at-double-the-rate-of-other-continents/" target="_blank" rel="noopener">cosmosmagazine.com</a> and was written by Matthew Agius.</strong></p> <p><em>Image: Getty</em></p>

Cold homes increase the risk of severe mental health problems – new study

<p>Concerns about <a href="https://theconversation.com/energy-crisis-the-uk-is-still-heading-for-widespread-fuel-poverty-despite-the-governments-price-cap-190290" target="_blank" rel="noopener">fuel poverty</a> and people not being able to heat their homes adequately are not new in the UK, but these worries have been <a href="https://www.theguardian.com/uk-news/2022/oct/26/warm-banks-open-wolverhampton-cost-of-living-crisis" target="_blank" rel="noopener">heightened</a> by significant increases in energy costs and the <a href="https://theconversation.com/the-cost-of-living-crisis-has-been-many-years-in-the-making-but-politicians-on-both-sides-ignore-this-189483" target="_blank" rel="noopener">cost-of-living crisis</a>. And as winter approaches, things are about to get a lot worse.</p> <p>Despite a relatively mild climate, the UK has higher levels of excess winter deaths – deaths associated with cold weather – than <a href="https://linkinghub.elsevier.com/retrieve/pii/S0140673614621140" target="_blank" rel="noopener">many colder countries</a>. This greater exposure to cold, despite milder weather, is related to poor housing quality, the high cost of heating homes and poverty.</p> <p>We know quite a lot about how living in a home that you can’t keep warm enough affects your physical health. Colder temperatures <a href="https://www.instituteofhealthequity.org/resources-reports/the-health-impacts-of-cold-homes-and-fuel-poverty/the-health-impacts-of-cold-homes-and-fuel-poverty.pdf" target="_blank" rel="noopener">suppress the immune system</a>, for example. But we know relatively little about the effects on mental health. <a href="https://doi.org/10.1016/j.socscimed.2022.115461" target="_blank" rel="noopener">Our new research</a> shows that living in a cold home is a significant mental health risk.</p> <p>Living in a cold home can affect your mental health in several ways. For many, heating costs are a source of stress and financial strain. Not being able to keep your home and family comfortably warm reduces feelings of control and autonomy over your environment. People who are unable to heat their home often adopt coping mechanisms that <a href="https://onlinelibrary.wiley.com/doi/10.1111/j.1365-2524.2005.00558.x" target="_blank" rel="noopener">limit socialising</a> – for example, not inviting friends over and going to bed early to keep warm. And many people are just worn down by the drudgery of a whole winter of being uncomfortably cold.</p> <p>Using <a href="https://www.understandingsociety.ac.uk/" target="_blank" rel="noopener">data</a> from a large representative sample of adults in the UK, we followed people over many years and tracked the effect of being unable to keep your home warm on mental health.</p> <p>When people’s homes became cold, their risk of severe mental distress significantly increased. For people who previously had no mental health problems, the odds of severe mental distress doubled when they had a cold home, while for those who had some (but not severe) mental health symptoms, the risk tripled (see chart below). We found these effects even after taking into account many other factors associated with mental health, including income.</p> <p><strong>Odds of reporting severe mental distress following transition into cold housing compared to those who remained in warm homes</strong></p> <figure class="align-center "><img src="https://images.theconversation.com/files/492381/original/file-20221028-61968-sxkqgr.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/492381/original/file-20221028-61968-sxkqgr.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=483&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/492381/original/file-20221028-61968-sxkqgr.png?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=483&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/492381/original/file-20221028-61968-sxkqgr.png?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=483&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/492381/original/file-20221028-61968-sxkqgr.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=607&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/492381/original/file-20221028-61968-sxkqgr.png?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=607&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/492381/original/file-20221028-61968-sxkqgr.png?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=607&amp;fit=crop&amp;dpr=3 2262w" alt="" /><figcaption><span class="attribution">author provided</span></figcaption></figure> <p>Sadly, the risk of living in a cold home differs greatly across the UK population. Lone parents and people who are unemployed or long-term sick are much more likely to live in cold homes. There is also significant inequality across ethnic groups – more than 12% of black people live in cold homes compared with under 6% of white British people, for example. Those who rent rather than own their home are also far more likely to live in cold homes, for social renters this is despite the, on average, <a href="https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/1088447/EHS_Housing_quality_and_condition_report_2020.pdf" target="_blank" rel="noopener">higher quality and</a><a href="https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/1091144/Energy_Report_2020_revised.pdf" target="_blank" rel="noopener">efficiency</a> of social rented homes.</p> <p>Putting on another jumper won’t be enough to get many in the UK through the coming winter. And mental health distress is just one consequence. Cold homes cause issues with significant personal and societal costs – from individual health effects to the increased pressure on the NHS, as well as broader economic loss due to missed work. Rishi Sunak’s new government needs to help people live in adequately warm homes this winter. But how?</p> <p>The older age of housing in the UK is <a href="http://www.instituteofhealthequity.org/projects/the-health-impacts-of-cold-homes-and-fuel-poverty" target="_blank" rel="noopener">heavily implicated</a> in the UK’s high levels of cold. Support for energy efficiency improvements is therefore a possible means of reducing cold homes. This will also mean tackling the so-called “split incentive” in the private rented sector, which houses a significant proportion of households. The split incentive refers to the challenge of the benefits of improvements not being experienced by the property owners but by tenants, reducing the incentive for owners to invest. This results in poorer quality and more expensive homes for renters.</p> <p><strong>Heat or eat? Most can’t afford either</strong></p> <p>The high proportion of cold homes in the social housing sector – despite having the best average energy efficiency due to insulation and building types (flats) – shows that energy efficiency improvements alone will not eliminate cold. <a href="https://www.resolutionfoundation.org/publications/the-living-standards-outlook-2022/" target="_blank" rel="noopener">Incomes in the UK are falling</a>. Benefit levels are <a href="https://theconversation.com/raising-benefits-in-line-with-earnings-will-make-the-poor-worse-off-heres-why-192880" target="_blank" rel="noopener">painfully low</a> and worsened by policies including the benefit cap, two-child limit and sanctions. Years of cuts and <a href="https://www.jrf.org.uk/file/59072/download?token=acsEgZp7&amp;filetype=briefing" target="_blank" rel="noopener">below inflation rises</a> mean that the term “heat or eat”, used to describe difficult spending decisions for low-income households, is now out of date, as <a href="https://www.jrf.org.uk/file/59191/download?token=PCFIM8W9&amp;filetype=briefing" target="_blank" rel="noopener">many can afford neither</a>.</p> <p>The combination of low household incomes with surging energy costs has created devastating pressure on household budgets. While the energy cap has limited energy cost increases below the worst estimates, energy bills have still <a href="https://theconversation.com/energy-crisis-the-uk-is-still-heading-for-widespread-fuel-poverty-despite-the-governments-price-cap-190290" target="_blank" rel="noopener">more than doubled in the past year</a>. And prepayment meters mean that those the with the least end up paying the most.</p> <p>There are, therefore, many areas for potential government intervention, and clear evidence that failing to intervene will cause harm to health.<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/193125/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em>Writen by Amy Clair.

With the strokes of a guitar solo, Joni Mitchell showed us how our female music elders are super punks

<p>The iconic Joni Mitchell’s recent surprise performance at the <a href="https://www.youtube.com/watch?v=jxiluPSmAF8&amp;feature=youtu.be">2022 Newport Folk Festival</a> prompted a world-wide outpouring of love and respect. </p> <p>This was her first musical performance since suffering from a brain aneurysm in 2015 that left her unable to walk and talk. Last year, she spoke of having <a href="https://www.nme.com/en_au/news/music/joni-mitchell-addresses-health-issues-in-rare-speech-at-2021-kennedy-center-honors-3112447">polio as a child</a> as “a rehearsal for the rest of my life”. </p> <p>The tributes for Mitchell celebrated her triumph from illness to recovery, but they also paid homage to Mitchell’s career that has pivoted on protest. </p> <p>Mitchell is largely associated with folk scenes of the 60s and 70s. She has produced a prolific body of work, advocating for social change. As a committed activist she has spoken against environmental degradation, war, LGBTQI+ discrimination, and most recently, removed <a href="https://www.theverge.com/2022/1/29/22907696/joni-mitchell-spotify-joe-rogan-podcast-misinformation-covid-19">her music catalogue</a> from Spotify in a protest against anti-vaccine propaganda. </p> <p>Now, with the <a href="https://www.youtube.com/watch?v=G7wOdpxGctc">strokes of a guitar solo</a> she repositioned herself from folk hero to punk provocateur, defying the “permissible” ways older women “should” behave. </p> <p>In commanding public space and using one of the most traditionally masculinised expressions of popular music practice, she directly challenged the sorts of expectations many people have around gendered norms, particularly what women in their elder years look and sound like.</p> <h2>Not everyone gets to age on stage</h2> <p>Some of the most persistent social restrictions placed on women and gender diverse musicians are in relation to age. </p> <p>Ongoing expectations of older women are to be passive, quiet and very much in the background. They are rarely asked, or expected, to “take up space” in the same ways their male counterparts do. </p> <p>Whereas men step through phases of youthful experimentation into established music legends, there are tiresome obstacles for female and gender diverse people to do the same. </p> <p>And while exceptions are often exceptional, they are not plentiful.</p> <p>It’s not just age. Women have long been sidelined when it comes to acknowledging their skills on the electric guitar. Much like Mitchell.</p> <p>The electric guitar has been an important part of rock and punk genres. There is a symbiotic relationship between how these genres – and the instrumentation that defines them – have unwittingly become gendered. The electric guitar solo in particular has come to be associated with machismo: fast, loud, expert, brave. </p> <p>If you like to imagine a world where women don’t exist, google “best guitar solos ever”. </p> <p>A recent <a href="https://www.nytimes.com/interactive/2022/04/02/opinion/grammys-rock-guitar-solo.html">New York Times article</a> suggested things are starting to change. Citing guitarists like Taja Cheek and Adrianne Lenker, the Times suggested the guitar solo has shifted from a macho institution into a display of vulnerability, a moment (perhaps many) of connectivity. </p> <p>Mitchell’s performance sits somewhere in this domain. </p> <p>For the hundreds of thousands of women and gender diverse guitarists world-wide, myself included, the electric guitar and the genres it is entwined with offer a cool, optional extra: to test the cultural norms of gender with other markers of identity like class, culture, sexuality and age, to blur ideas of what we should and shouldn’t do.</p> <h2>Australian women to the front</h2> <p>Australian women and gender diverse rock and punk musicians are often subject to a double act of erasure – missing from localised histories, and also from broader canons of contemporary music, which often remain persistently rooted in the traditions of the UK and the US.</p> <p><a href="https://www.goodreads.com/en/book/show/55669013-my-rock-n-roll-friend">Tracey Thorn’s brilliant biography</a> of the Go-Between’s drummer Lindy Morrison is a love lettered homage that steps out the complex local, emotional, personal and structural ways that Australian women and gender diverse people are often omitted from cultural spaces. </p> <p>“We are patronised and then we vanish,” writes Thorn.</p> <p>The work of women and gender diverse artists is often compared to the glossy pedestal of the male creative genius.</p> <p>In this light, we don’t play right, we don’t look right, we don’t sound right. </p> <p>And then, somehow, we don’t age right. </p> <p>Other reasons are far more mundane. Women contribute around <a href="https://www2.deloitte.com/au/en/blog/economics-blog/2019/Value-unpaid-work-care.html">13 hours more unpaid work</a> than men each week. </p> <p>Carrying plates overflowing with generous gifts of labour, the maintenance of a music practice – a largely underpaid endeavour – is often the first to fall by the wayside. </p> <p>Add to the mix ingrained social networks of knowledge sharing, and the dominance of men making decisions higher up the chain, and it is easy to see how women and gender diverse musicians stay submerged as men rise to the limited real estate of music elders. </p> <p>The problem isn’t so much about starting up. It’s about finding the time to keep up.</p> <h2>Our female and gender diverse music elders</h2> <p>There are so many Australian female and gender diverse music elders. Some are visible, but many ripple beneath the surface. </p> <p>Regardless of genre, in maintaining decades-long practice, they are the super punks whose legacy can be heard in venues across the country. </p> <p>The challenge now is to support the current crop of excellent musicians beyond the flushes of youth so that we have a more sustainable, textured and diverse Australian music culture. One where Mitchell’s defiance of expectations represents the status quo of how older women should and can be.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://theconversation.com/with-the-strokes-of-a-guitar-solo-joni-mitchell-showed-us-how-our-female-music-elders-are-super-punks-188075" target="_blank" rel="noopener">The Conversation</a>. </em></p>

Australian women are less likely to receive pre-hospital stroke care than men

<p>Paramedics are failing to recognise strokes in women as much as they do for men, according to a new <a href="https://newsroom.unsw.edu.au/news/health/women-less-likely-receive-pre-hospital-stroke-care-men" target="_blank" rel="noreferrer noopener">study</a> of New South Wales stroke patients. Researchers suggest that clinician sex bias might be the cause.</p> <p>In 2018 it was <a href="https://www.aihw.gov.au/reports/heart-stroke-vascular-diseases/hsvd-facts/contents/heart-stroke-and-vascular-disease-and-subtypes/stroke" target="_blank" rel="noreferrer noopener">estimated</a> that 387,000 Australians aged over 15 years had experienced a stroke at some point in their lives. The success of treatment is very time dependent, so it’s critical that patients suffering from stroke are identified as soon as possible, preferably before arriving at hospital.</p> <p>But according to the study by Australian researchers, women (aged under 70) suffering with stroke were less likely than men to receive stroke care management prior to hospital admission – despite being more likely to arrive at hospital by ambulance.</p> <p>This is concerning, as other research shows stroke outcomes are <a href="https://pubmed.ncbi.nlm.nih.gov/31719135/" target="_blank" rel="noreferrer noopener">generally worse</a> for women than men – with greater stroke-related disability and poorer subsequent quality of life.</p> <p>“Our study suggests that better recognition of stroke symptoms in women by ambulance staff could ensure the right treatment is started as early as possible and give them the best opportunity for recovery,” says lead author Dr Xia Wang, research fellow at The George Institute for Global Health in Sydney.</p> <p>There are two types of stroke: ischaemic stroke occurs when a vessel supplying blood to the brain becomes blocked, and haemorrhagic stroke occurs when one ruptures and begins to bleed. This can cause parts of the brain to die – resulting in impairment that can affect things like speech, movement, and communication – or can often be fatal.</p> <p>Thanks to development in medical research <a href="https://www.nhs.uk/conditions/stroke/treatment/" target="_blank" rel="noreferrer noopener">treatment for stroke</a> is changing, but the efficacy of these treatments is highly time-dependent and rapid and accurate pre-hospital assessment is critical for successful outcomes.</p> <p>“When stroke is not recognised early, delays can have serious consequences,” says co-author Dr Cheryl Carcel, senior research fellow and academic lead of the George Institute’s Global Brain Health Initiative.</p> <p>“Procedures for in-ambulance stroke care ensure patients with stroke symptoms are brought to a high-level specialised facility quickly to receive life-saving treatment.”</p> <p>In a population-based cohort study, researchers analysed data from more than  200,0000 patients (51% women) admitted to NSW hospitals between July 2005 and December 2018 and subsequently diagnosed as having a stroke.</p> <p>Just over half of all stroke patients were taken to hospital via ambulance, with women (52.4%) more likely than men (47.9%) to arrive this way.</p> <p>Despite this, women were less likely to receive stroke care management prior to hospital admission.</p> <p>“Among patients under 70 years of age, women were less likely than men to be assessed by paramedics as having a stroke, but there was no significant difference for older patients,” the authors say.</p> <p>Instead, they were more frequently assessed by paramedics as having conditions which mimic stroke – like headache or migraine, anxiety, and unconsciousness – which contributed to a delay in the recognition and treatment of stroke.</p> <p>There was no significant difference for older patients.</p> <p>Health professionals know that on initial presentation, <a href="https://pubmed.ncbi.nlm.nih.gov/31114842/" target="_blank" rel="noreferrer noopener">atypical clinical symptoms of stroke</a> occur more frequently in women. So, these findings could be due to a difference in symptoms, although it’s also possible that implicit sex bias exists amongst healthcare providers.</p> <p>“While there aren’t any studies looking at clinician sex bias in stroke, we have evidence from other countries where it is happening in <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3810172/" target="_blank" rel="noreferrer noopener">coronary artery disease</a>,” explains Carcel.</p> <p>This has also been <a href="https://www.sciencedirect.com/science/article/abs/pii/S0002870321001885?via%3Dihub" target="_blank" rel="noreferrer noopener">found</a> to be the case for myocardial infarction (heart attack), with women less likely to be assessed by paramedics as having MI than men.</p> <p>“Greater awareness among all health professionals about differences in symptom presentation between men and women could help address this bias,” concludes Carcel. “In the case of stroke, this is particularly important for ambulance staff, so that women are identified early and treatment is commenced even before they reach the hospital.”</p> <p>This article originally appeared on <a href="https://cosmosmagazine.com/people/australian-women-stroke-care/" target="_blank" rel="noopener">Cosmos</a>. </p> <p><em>Image: Getty</em></p>
