Teacher's wild salary sparks heated debate

A teacher's hefty salary has sparked a major debate online, with some people arguing that some educators are "extremely overpaid". A Melbourne man was quizzed on the street by Getahead, an app that matches workers with employers, as he revealed he has worked as a drama teacher at a high school for decades. “I’m a teacher and I make just north of $160,000,” he revealed. “I’ve been teaching for 27 years,” he added. “Started as an actor and then moved into teaching. The workload is alright, I’m on holidays at the moment." “School holidays are always good. But when you are working, you’re doing a lot of after hours and things like that. “It’s definitely worth it though. I’d encourage anyone to get into it. For any actors out there, drama teaching is the next best thing." “You get to do your craft every day and you get to teach the future of actors. Do what you want to do, until you can’t do it anymore and then find something else that will be good to do." He said, “But you gotta follow your passion first.” The video racked up hundreds of comments, with many stunned at the man’s salary. “There’s no way,” one said, with another adding, “I am in the wrong profession.” In another clip from Getahead, a different woman was quizzed about her salary and it is revealed she is also a teacher. She claims to be raking in $110,000 a year working at a high school, but said the idea teachers get “loads of holidays” is a “total myth”, adding that "the workload is huge." While many commenters were stunned by the significant salaries, there were some that even went as far as to claim teachers were being “overpaid”. “Teachers are extremely overpaid,” one claimed. “The most they should be paid is $30k – $40k.” “$110k for a schoolteacher, at this point we are handing out money,” another said. “If they are earning that much money why are they all saying they need more?” another asked, “That’s an excellent wage.” Other teachers sounded shocked at these figures, with many saying they were not making anywhere near that amount. “That’s not close to average, I’m a maths and science teacher at a high school and I earn $84k,” one shared. “I’ve been teaching for 43 years, I’m head of a subject area and have several post grade qualifications, and I don’t make anywhere near that,” another added.

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

<div class="theconversation-article-body"><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> Extreme heat is a silent killer. 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. 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. 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&type=pdf&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>. <h2>Health risks and heat</h2> <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. 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>. 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 American Journal of Public Health</a> points out that the 1995 heat wave in Chicago likely contributed to hundreds more deaths than had first been attributed to heat itself. <h2>Who is at risk?</h2> 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. 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. 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. 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. <h2>Taking action at the community level</h2> From this Global North perspective, the community members who are most likely to die from extreme heat included: <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> This problem is not going away. 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: <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. Doing this, especially with a fan blowing, can be surprisingly effective.</li> <li>Learn and share the <a href="https://www.canada.ca/en/health-canada/services/publications/healthy-living/fact-sheet-staying-healthy-heat.html">warning signs of heat-related illness</a>.</li> <li>Make sure they drink plenty of water and other replenishing fluids.</li> </ul> While we must do our best to limit climate change to keep our planet from getting ever hotter, we must also make every effort to protect the vulnerable from the impacts of the heat that is already here.<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/236829/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/myles-david-sergeant-1542267">Myles David Sergeant</a>, Assistant Clinical Professor, Department of Family Medicine, <a href="https://theconversation.com/institutions/mcmaster-university-930">McMaster University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

How do we save ageing Australians from the heat? Greening our cities is a good start

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/claudia-baldwin-248780">Claudia Baldwin</a>, <a href="https://theconversation.com/institutions/university-of-the-sunshine-coast-1068">University of the Sunshine Coast</a>; <a href="https://theconversation.com/profiles/jason-byrne-6066">Jason Byrne</a>, <a href="https://theconversation.com/institutions/university-of-tasmania-888">University of Tasmania</a>, and <a href="https://theconversation.com/profiles/tony-matthews-234160">Tony Matthews</a>, <a href="https://theconversation.com/institutions/griffith-university-828">Griffith University</a> Heatwaves have killed more Australians than <a href="https://ama.com.au/ausmed/heatwave-health-warning">road accidents</a>, fires, floods and <a href="https://www.sciencedirect.com/science/article/pii/S1462901114000999">all other natural disasters combined</a>. Although <a href="https://theconversation.com/forget-heatwaves-our-cold-houses-are-much-more-likely-to-kill-us-83030">recent research</a> shows extreme cold is a worry in some parts of Australia, <a href="https://theconversation.com/2018-19-was-australias-hottest-summer-on-record-with-a-warm-autumn-likely-too-112616">our hottest summer on record</a> points to more heat-related deaths to come. The <a href="https://theconversation.com/the-stubborn-high-pressure-system-behind-australias-record-heatwaves-110442">record heatwaves</a> have highlighted the damaging effects of heat stress. Understandably, it’s becoming a major <a href="https://ama.com.au/ausmed/heatwaves-nation%E2%80%99s-deadliest-natural-disaster-0">public health challenge</a>. The risk of extreme heat events and the adverse impacts on older people has been extensively <a href="https://jech.bmj.com/content/64/9/753.short">discussed in research</a>. Remarkably, very little attention has been paid to the role of urban greenery in reducing heat stress for seniors. Older people are particularly at risk of heat stress. Pre-existing medical conditions and limited mobility increase their vulnerability. <a href="http://www.cmaj.ca/content/182/10/1053.short">Deaths of older people increase</a> during extreme heat events. The physical features of urban areas shape the capacity of older adults to engage in many activities when it’s hot. These include vegetation volume and coverage, <a href="https://theconversation.com/building-cool-cities-for-a-hot-future-57489">thermal design</a>, and the extent of shading in public areas and walkways. Increasing urban greenery may offer a way to improve older people’s comfort and social experience. <h2>Ageing adds urgency to greening</h2> It is expected <a href="http://www.un.org/en/sections/issues-depth/ageing/">20% of the global population</a> will be older than 60 by 2050. The figure for Australia <a href="http://www.abs.gov.au/ausstats/abs@.nsf/mediareleasesbyTopic/2CA2134677EF9D03CA257C2E0017283B?OpenDocument">is even higher</a>, at 23%. This means that by 2050 around one in four Australians will be more vulnerable to extreme heat. <figure class="align-right zoomable"></figure> Climate change may make the problem worse by <a href="https://www.sciencedirect.com/science/article/pii/S0749379708006867">fuelling even more extreme heat</a> events. Planning our urban centres to meet the needs of a <a href="https://www.aihw.gov.au/reports/older-people/older-australia-at-a-glance/contents/demographics-of-older-australians">rapidly ageing population</a> is a matter of urgency. Urban greening to reduce their vulnerability to heat stress should be central to this agenda. It can also improve people’s quality of life, reduce <a href="https://www.sciencedirect.com/science/article/abs/pii/S1353829208001172">social isolation and loneliness</a>, and ease the burden on health systems. An important task is matching the design of communities with the needs of an ageing population. Where older adults live and the quality of their local areas strongly influence their lived experiences. Yet <a href="https://journals.sagepub.com/doi/abs/10.1177/0885412217704649">recent research</a> found the experiences of seniors were often not accounted for in research on neighbourhood design. <h2>What about aged care?</h2> People face choices about where they live as they age. The common choices are to “<a href="https://theconversation.com/for-australians-to-have-the-choice-of-growing-old-at-home-here-is-what-needs-to-change-91488">age in place</a>” or to move into aged care. Ageing in place includes living in one’s own home or <a href="https://theconversation.com/co-housing-works-well-for-older-people-once-they-get-past-the-image-problem-79907">co-habiting with relatives or friends</a>. Around 90% of Australian seniors <a href="https://www.pc.gov.au/research/completed/housing-decisions-older-australians/housing-decisions-older-australians.pdf">choose this option</a>, with the remainder opting for aged-care facilities. If one in ten Australian seniors live in aged-care facilities, it is clear these should be designed to minimise heat stress. This isn’t just good for residents; it may also benefit operators by lowering health-care and electricity costs. While these facilities are purpose-built for older people, many in Australia were built well over a decade ago, when heat stress was not such a large concern. Many more facilities are being built now and will be into the future. Yet it is uncertain whether they are being actively designed to reduce the impacts of heat. <h2>What has our research found?</h2> We recently conducted a focus group to investigate this issue. Participants were senior managers from four large corporate providers of aged care in Australia. We investigated if and how providers try to minimise heat stress through design. We also sought to understand the rationales used to support these design approaches. Several participants reported on refurbishments that they expect will have cooling effects. Cited design approaches included green roofs and walls, as well as sensory gardens. Other expected benefits included reducing anxiety and improving the mental health of residents. The fact that single design interventions could produce multiple benefits improved the potential for corporate buy-in. Participants expected that increasing green space and green cover would give their facilities a competitive advantage by attracting more clients and providing a better working environment for staff. Participants also reported on challenges of including greening in their projects. For example, the benefits of trees were weighed against concerns about roots disrupting footpaths and becoming trip hazards. Species selection was another concern, with fears that inappropriate plants could die and undermine support for greening programs. Our research suggests that more can be done to make cities hospitable for older people, especially during extreme heat. Urban greening is a start. Encouraging aged-care providers to adopt green infrastructure will have benefits. But we should also consider reforms to planning systems and urban design to better protect older people who choose to age in place.<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/112613/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/claudia-baldwin-248780">Claudia Baldwin</a>, Associate Professor, Urban Design and Town Planning, Sustainability Research Centre, <a href="https://theconversation.com/institutions/university-of-the-sunshine-coast-1068">University of the Sunshine Coast</a>; <a href="https://theconversation.com/profiles/jason-byrne-6066">Jason Byrne</a>, Professor of Human Geography and Planning, <a href="https://theconversation.com/institutions/university-of-tasmania-888">University of Tasmania</a>, and <a href="https://theconversation.com/profiles/tony-matthews-234160">Tony Matthews</a>, Senior Lecturer in Urban and Environmental Planning, <a href="https://theconversation.com/institutions/griffith-university-828">Griffith University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

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

<div class="theconversation-article-body"> <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> 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. 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. 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. <h2>What heat does to your hair</h2> 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. 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. 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. Inside that outer layer is the cortex, which is rich in a protein called keratin. 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. 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. 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>. 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. 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”. This steam bubbling or bursting through the hair can <a href="https://pubmed.ncbi.nlm.nih.gov/21443842/">cause substantial damage</a>. 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. Once heat damage is done, regardless of whether it is severe or mild, the best remaining options are symptom management or a haircut. For all of these reasons, when you’re planning to heat treat your hair, protection is a good idea. <h2>How hair protectants work</h2> When you spray on a hair protectant, many possible key ingredients can go to work. They can have <a href="https://library.scconline.org/v062n01/15">daunting-looking names</a> like polyvinyl pyrrolidone, methacrylates, polyquaterniums, silicones and more. These materials are chosen because they readily stick onto your hair, creating a coating, a bit like this: <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/615002/original/file-20240822-16-beyt90.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/615002/original/file-20240822-16-beyt90.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/615002/original/file-20240822-16-beyt90.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=225&fit=crop&dpr=1 600w, https://images.theconversation.com/files/615002/original/file-20240822-16-beyt90.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=225&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/615002/original/file-20240822-16-beyt90.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=225&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/615002/original/file-20240822-16-beyt90.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=283&fit=crop&dpr=1 754w, https://images.theconversation.com/files/615002/original/file-20240822-16-beyt90.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=283&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/615002/original/file-20240822-16-beyt90.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=283&fit=crop&dpr=3 2262w" alt="A cartoon of coating attached to a strand of hair." /></a><figcaption>Hair protectant applies a coating to your hair.

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"><a href="https://theconversation.com/profiles/martin-jucker-379172">Martin Jucker</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> 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>. 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. Here’s what’s happening – and what it might mean for the rest of this year’s weather. <h2>When the stratosphere heats up</h2> 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. 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>. 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. 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>). <h2>Pushing polar weather our way</h2> 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. 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>. 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. 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. 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. <h1>This winter’s weirdness</h1> 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. But there are indications that the stratosphere is having some influence on our weather this winter. 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. These numbers mean that, technically, the event does not qualify as a sudden stratospheric warming. However, further warming may still occur. 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. 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>. 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. 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. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/611211/original/file-20240804-19-sp862a.png?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/611211/original/file-20240804-19-sp862a.png?ixlib=rb-4.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/611211/original/file-20240804-19-sp862a.png?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=300&fit=crop&dpr=1 600w, https://images.theconversation.com/files/611211/original/file-20240804-19-sp862a.png?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=300&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/611211/original/file-20240804-19-sp862a.png?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=300&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/611211/original/file-20240804-19-sp862a.png?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=377&fit=crop&dpr=1 754w, https://images.theconversation.com/files/611211/original/file-20240804-19-sp862a.png?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=377&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/611211/original/file-20240804-19-sp862a.png?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=377&fit=crop&dpr=3 2262w" alt="Diagram showing atmospheric warming and winds" /></a><figcaption>How initial warming high in the stratosphere ends up changing winds near the surface and pushing polar weather further north. <a class="source" href="https://stratobserve.com">Z.D. Lawrence / StratObserve / Annotated by Martin Jucker</a></figcaption></figure> <h1>A surface disturbance</h1> The main reason for the polar vortex to slow down is disturbances from the surface. Weather over the Amundsen Sea near Antarctica in the South Pacific is <a href="https://doi.org/10.1175/JCLI-D-22-0425.1">an important source</a> of these disturbances. This year, we have seen disturbances of this sort. There have been <a href="https://www.theguardian.com/world/article/2024/aug/01/antarctic-temperatures-rise-10c-above-average-in-near-record-heatwave">near-record surface temperatures around Antarctica</a>. These disturbances may be due to the globally high ocean temperatures, or even lingering effects of the <a href="https://doi.org/10.1175/JCLI-D-23-0437.1">eruption of the Hunga Tonga volcano in 2022</a>. But more research will be required to confirm the causes. <h1>What should we expect for the rest of the year?</h1> There are two pathways until the end of the year. One is that the stratospheric winds and temperatures recover to their usual values and no longer influence surface weather. This is what the forecasts from <a href="https://ozonewatch.gsfc.nasa.gov">Ozone Watch</a> seem to suggest. Another is that the stratosphere keeps warming and the winds keep being slower all the way into summer. In this scenario, we would expect a persistent negative Southern Annular Mode, which would mean a spring and potentially even summer with warmer and drier than usual weather over southeastern Australia, and a small ozone hole. The seasonal forecasting models from the European Centre for Medium Range Weather Forecasts <a href="https://x.com/drahbutler/status/1819142206348759170?s=46&t=sayfGwpo3_s310BwYpcdcQ">seem to favour this second scenario</a>. <a href="https://theconversation.com/profiles/martin-jucker-379172">Martin Jucker</a>, Senior Lecturer in Atmospheric Science, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Your parents’ income doesn’t determine yours – unless you’re ultra rich or extremely poor

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/catherine-de-fontenay-5631">Catherine de Fontenay</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> Australia is among the strongest global performers in terms of income mobility between the generations, according to a new <a href="https://www.pc.gov.au/research/completed/fairly-equal-mobility">Productivity Commission report</a>. The country’s long-term economic growth has led to each generation earning more than the last, on average. Our report finds 67% of the so-called <a href="https://www.businessinsider.com/xennials-born-between-millennials-and-gen-x-2017-11">“Xennial”</a> generation – those born in 1976–1982, on the cusp of the Millennial/Gen X divide – earn more than their parents did at a similar age. This is particularly true of those born into poorer families. <hr /> <iframe id="NsmB3" class="tc-infographic-datawrapper" style="border: 0;" src="https://datawrapper.dwcdn.net/NsmB3/" width="100%" height="400px" frameborder="0" scrolling="no"></iframe> <hr /> When we look at where people rank in an income distribution, the picture is a little less rosy. While children with parents at the bottom or top of the income scale are more likely to remain there, almost 15% of people with parents in the lowest income decile, remain there while just 6% move to the top. And those living in poverty - who often include renters, people from migrant backgrounds who don’t speak English at home and single parents - face some of the biggest barriers to improving their economic lot. <a href="https://www.pc.gov.au/research/completed/fairly-equal-mobility">Fairly Equal? Economic mobility in Australia</a>, released on Thursday, measures intergenerational income mobility by examining the relationship between a person’s income and the eventual income of their children. <h2>Measuring inequality</h2> Most countries anxiously monitor income distribution and economic mobility amid concerns inequality may be increasing. And countries with high inequality tend to have low mobility: the rungs of the social ladder are far apart making it difficult to move up to the next level. If mobility is low, the consequences are serious. Low mobility is discouraging, unproductive and unstable. If young people have little chance of achieving their aspirations, their wellbeing is affected. <a href="https://ideas.repec.org/p/cor/louvco/2023026.html">Social unrest is more likely</a>. And the abilities of young people from less affluent backgrounds are under-used. The next tech entrepreneur Steve Jobs may never be discovered, and many other opportunities are lost. In Australia we are used to thinking of ourselves as having inequality and mobility somewhere between Scandinavia and the US; but that comparison is not as comforting as it used to be, if inequality and mobility are worsening in the US. Our report considers people’s income mobility over the course of their lives, and across generations. If income mobility is low, people will struggle to recover from initial disadvantage, and those born into privilege will be financially secure. First we look at whether people move in the income distribution; there is a surprising amount of movement. And we look for evidence people can access opportunities throughout life, after setbacks. <h2>Recovering from setbacks</h2> There is not much evidence of recovery after a person experiences a severe illness or a job loss, perhaps because the causal factors are still at work. More encouragingly, the income of women who experience separation <a href="https://melbourneinstitute.unimelb.edu.au/__data/assets/pdf_file/0020/4815110/HILDA-User-Manual-Release-22.0.pdf">does increase</a>, eventually restoring the buying power of their household. This is in part due to well-targeted government support. For intergenerational mobility, we extended the dataset developed by <a href="https://www.aeaweb.org/articles?id=10.1257/jel.20211413">an analytical dataset</a> to measure the influence parents’ income had on the income their offspring were likely to earn. We found Australia’s intergenerational mobility is actually higher than the <a href="https://onlinelibrary.wiley.com/doi/10.1111/sjoe.12197">Scandinavian</a> countries, and second only to <a href="https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3662560">Switzerland</a> among comparable studies. <hr /> <iframe id="5DFB9" class="tc-infographic-datawrapper" style="border: 0;" src="https://datawrapper.dwcdn.net/5DFB9/" width="100%" height="400px" frameborder="0" scrolling="no"></iframe> <hr /> In all countries studied there was some link between parents’ income mobility and that of children, because parents pass on tastes, ambitions and abilities. And there was greater correlation between the incomes of mothers and daughters, and fathers and sons than with parents of the opposite gender, perhaps because of role model effects. <hr /> <iframe id="BJ4hD" class="tc-infographic-datawrapper" style="border: 0;" src="https://datawrapper.dwcdn.net/BJ4hD/" width="100%" height="400px" frameborder="0" scrolling="no"></iframe> <hr /> While Australia’s strong income mobility between generations is remarkable, it’s concerning there is less mobility among those at the very bottom and top of the income distribution scale. The fact children born into the poorest families were more likely to remain in the lowest deciles, while those born into the top earning families tended to remain in the top deciles, suggests privilege is often passed on. People who grew up in frequently poor households were <a href="https://melbourneinstitute.unimelb.edu.au/__data/assets/pdf_file/0009/3537441/HILDA-Statistical-report-2020.pdf">three time more likely</a> to be poor at age 26 to 32 than those who never experienced poverty. <hr /> <iframe id="SxHBo" class="tc-infographic-datawrapper" style="border: 0;" src="https://datawrapper.dwcdn.net/SxHBo/" width="100%" height="400px" frameborder="0" scrolling="no"></iframe> <hr /> And consistent with <a href="https://www.aihw.gov.au/getmedia/37c2c8b7-328c-41e1-bace-87ed7a551777/australias-welfare-chapter-2-summary-18sept2019.pdf.aspx">other studies</a> we found children whose family received government payments were twice as likely to receive support as adults, compared with those whose families received no help. <h2>Movement in the middle</h2> Taken together, these results suggest some segmentation of opportunities. In the middle of the income distribution, there are opportunities to get ahead, and individuals’ careers are not restricted by their families’ circumstances. At the bottom, things are a lot more “sticky”, and finding opportunities to permanently escape poverty is more difficult. Some of this boils down where people live, peers, school quality and local job options. Researchers <a href="https://www.aeaweb.org/articles?id=10.1257/jel.20211413">Deutscher and Mazumder</a> (2023) have shown regional economic conditions have a big impact on mobility, and we show remoteness limits movement out of poverty. Overall, the mobility picture is extremely good news for most Australians. But this should not blind us how difficult it is to move out of poverty, especially for those in remote areas. Identifying where mobility fails to deliver allows us to focus our policy response.<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/234158/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/catherine-de-fontenay-5631">Catherine de Fontenay</a>, Honorary Fellow, Department of Economics, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

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

<div class="theconversation-article-body"><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> 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>. 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. 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. So why doesn’t drinking water help make that spicy feeling go away? And what would work better instead? <h2>Water-loving and water-hating molecules</h2> 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. Look what happens when you try to mix hydrophobic sand with water. <figure><iframe src="https://www.youtube.com/embed/H8cj9CpHW7w?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> On the other hand, hydrophilic molecules love water and are very happy to mix with it. 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. If you try to wash hydrophobic capsaicin away with water, it won’t be very effective, because hydrophilic and hydrophobic substances don’t mix. 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. 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”. 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: <figure><iframe src="https://www.youtube.com/embed/s5yfs-Pr_y8?wmode=transparent&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> A swig of oil would likely be effective, but is perhaps not so palatable. Milk makes for an ideal choice for two reasons. The first is that milk contains hydrophobic fats, which the capsaicin will more easily dissolve in, allowing it to be washed away. 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: <figure><iframe src="https://www.youtube.com/embed/S4XeQhZRLDE?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> 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>. <h2>OK but I hate drinking milk. What else can I try?</h2> 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. Ice cream would also work, as it contains both casein and large amounts of hydrophobic substances. 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. What about reaching for that ice cold beer? 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. 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. Your curry and beer may taste great together, but that’s likely the only benefit. 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.<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/226624/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/daniel-eldridge-1494633">Daniel Eldridge</a>, Senior Lecturer in Chemistry, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Cafe targeted online for charging customer a "heating fee"

A cafe in Melbourne has copped a wave of backlash online after allegedly charging a customer to heat up his muffin for breakfast. The disgruntled diner took to Facebook to complain about the extra fee on his $7 muffin at the cafe and claimed the first he knew of it was when he saw it on his receipt. His post went viral with hundreds of people slamming café etiquette and urging him to go to the ACCC. "A f***ing dollar to heat my muffin? It's cr*p like this that just makes you shake your head and question where it is all going," the customer wrote in his original post. The cafe has since hit back at the post, and the angry customer who wrote it, saying the extra charge had been an error despite Heat Standard $1.00 being written on the receipt. They also said the customer could have simply solved the issue in person rather than blasting them online. "We do not nor have we ever charged for any heating of our wonderful baked treats," the café spokesperson told <a href="https://www.dailymail.co.uk/femail/real-life/article-13465591/Melbourne-cafe-targeted-angry-mob-charging-1-heating-fee-muffin-Aussies-reveal-hidden-charges-theyve-hit-amid-cost-living-crisis.html" target="_blank" rel="noopener">Daily Mail Australia</a>. "Unfortunately this has become a mountain of an issue that could have easily been resolved without a lynch mob caused by negligence at the hands of an influential keyboard warrior who ironically sells the idea of spiritual life practices and being grounded yet flipped out over a muffin." The original post racked up more than 870 comments before it was deleted, and more than 1,000 reactions. Some of those who saw it went on to slam the cafe by sending them threatening messages, commenting on posts on Instagram and calling their business phone to hurl abuse. "It's a sad world when a local cafe that aims for nothing more then customer satisfaction and community values to be upheld gets threatening messages from rogue vigilantes about wanting to see us go out of business over a muffin being prepared and served to quality standards," the cafe owners said. The cafe responded to the growing backlash online by announcing their muffins would be free on Tuesday. Image credits: Facebook / Shutterstock

How extreme dieting can affect bone health

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/adam-taylor-283950">Adam Taylor</a>, <a href="https://theconversation.com/institutions/lancaster-university-1176">Lancaster University</a> In a recent Instagram post, the actor Jameela Jamil revealed she has poor bone density, despite only being in her 30s. Jamil blamed this finding on 20 years of dieting – urging her followers to be aware of the harms diet culture can do to your health. Bone density is important for many reasons, primarily because it acts as a reservoir for many of the important minerals our bones need to function well. Many factors can affect your bone density – and as Jamil has pointed out, diet is one component that has a significant effect on bone health. Bone is a living tissue. This means our skeleton <a href="https://www.sciencedirect.com/science/article/abs/pii/S1521690X08000869">grows and remodels itself</a> according to the stresses and strains it’s put under. Everything from fractures to exercise require our bones to change their shape or density. This is why a weightlifter’s skeleton is <a href="https://link.springer.com/article/10.1007/BF00298721">much denser</a> than a marathon runner’s. The biggest skeletal changes we experience happen in our younger years. But bones keep changing throughout our lives depending on how active we are, what our diet consists of, and if we’ve suffered an injury or disease. Bones are <a href="https://www.niams.nih.gov/health-topics/what-bone">made of proteins</a>, such as collagen, as well as minerals – largely calcium. This is a <a href="https://www.ncbi.nlm.nih.gov/books/NBK430714/">key mineral</a> for us, as it keeps our bones and teeth strong and helps repair and rebuild any injured bones. But other minerals and vitamins are also important. For example, vitamin D supports calcium, playing a key role in <a href="https://jamanetwork.com/journals/jamapediatrics/fullarticle/2761808">bone mineralisation</a>. This is where calcium <a href="https://www.ncbi.nlm.nih.gov/books/NBK279023/">combines with phosphate</a> in our bones to create the mineral crystal <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7264100/">hydroxyapatite</a>. This crystal is crucial to our bone mineral density (also known as “bone mass”), as it helps bones remodel and maintain their structural strength. <a href="https://www.nhs.uk/conditions/dexa-scan/">Dexa scans</a> – the type of scan Jamil referred to in her post – can measure the density of these crystals in bones. The <a href="https://theros.org.uk/information-and-support/osteoporosis/scans-tests-and-results/bone-density-scan-dxa/">more hydroxyapatite crystals</a> detected, the healthier the bones are. <figure class="align-center "><img src="https://images.theconversation.com/files/591182/original/file-20240430-18-u30byz.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/591182/original/file-20240430-18-u30byz.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=338&fit=crop&dpr=1 600w, https://images.theconversation.com/files/591182/original/file-20240430-18-u30byz.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=338&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/591182/original/file-20240430-18-u30byz.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=338&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/591182/original/file-20240430-18-u30byz.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=424&fit=crop&dpr=1 754w, https://images.theconversation.com/files/591182/original/file-20240430-18-u30byz.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=424&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/591182/original/file-20240430-18-u30byz.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=424&fit=crop&dpr=3 2262w" alt="The interior of bones, showing four depictions of bone density – from healthy to severe osteoporosis." /><figcaption>The more crystals detected, the better your bone density. <a class="source" href="https://www.shutterstock.com/image-illustration/osteoporosis-4-stages-one-picture-3d-524364046">Crevis/ Shutterstock</a></figcaption></figure> We hit peak bone mineral density in our <a href="https://pubmed.ncbi.nlm.nih.gov/35869910/">late teens and early 20s</a>, when our body has grown to full size and our metabolism is working its best. From here, it’s possible to maintain <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5684300/">stable bone mass</a> into your late 30s for women and early 40s for men, with the right diet and activity. But after this point, it begins to decline. <h2>Bone density</h2> We accrue calcium over many years. It initially comes from our mother, then later from our diet. Our body accrues calcium so it can adapt to times when calcium demand is greater than what we can get from our diet – such as during pregnancy, when the foetus needs calcium to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3355895/">build its own bones</a>. However, relying solely on this skeletal calcium reserve can’t be sustained for lengthy or repeated periods, because of how long it takes to be replenished. This is why diet is so important for bone density – and why a poor diet can cause extreme damage, especially when certain food groups or minerals are consistently left out. For instance, studies have shown consuming soft drinks, (<a href="https://pubmed.ncbi.nlm.nih.gov/17023723/">particularly cola</a>), more than four times a week is linked with <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7071508/">lower bone density</a> and increased fracture risk. This is true even after adjusting for many other variables that affect bone density. These carbonated and energy drinks contain <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2966367/">varying levels of vitamins</a> – often with none of the minerals, including calcium, that the body needs to function optimally. This causes the body to draw on its reserves if calcium isn’t being delivered elsewhere in the diet. Diets high in added sugar can also have a detrimental affect on the skeleton. Excess sugar causes inflammation and other physiological changes, such as <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9471313/">obesity</a>. Consuming high amounts of sugar is linked with <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2748414/">reduced calcium intake</a>, especially in children who substitute milk for sugary drinks. Excess sugar consumption also causes the body to <a href="https://jps.biomedcentral.com/articles/10.1007/s12576-016-0487-7">excrete excess calcium</a>, instead of reabsorbing it in the kidney as the body normally would. <a href="https://pubmed.ncbi.nlm.nih.gov/25491765/">Low- and high-fat diets</a> have also been associated with increased risk of <a href="https://www.nhs.uk/conditions/osteoporosis/">osteoporosis</a> (a condition that weakens bones) in women – though larger studies are needed to better understand the effects of removing whole food groups on bone health. <a href="https://www.nhs.uk/mental-health/conditions/anorexia/overview/">Anorexia nervosa</a> also has a significant affect on <a href="https://pubmed.ncbi.nlm.nih.gov/30817009">bone density</a> – affecting a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6959847/">majority of people</a> with the condition. Low bone mineral density – especially in the spine – puts people with anorexia at <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6959847/">increased risk of fractures</a> because their bone thickness is reduced, increasing the likelihood of developing osteoporosis, which is associated with increased fractures. Anorexia in young adulthood is particularly challenging. This is the stage where the skeleton is building itself to reach peak <a href="https://pubmed.ncbi.nlm.nih.gov/15574617/">bone mass</a>, so it’s depositing calcium at a record pace. When diet is insufficient and the body already starts drawing on its mineral reserves, there’s a potential that the bone density or calcium reserves in the body will never be optimal – increasing fracture risk for the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6746661/">rest of that person’s life</a>. <h2>Can bone health be fixed?</h2> Optimal bone health starts in utero, but our prepubescent years are key to <a href="https://pubmed.ncbi.nlm.nih.gov/26884506/">setting our skeleton up</a> for later life. People who are behind the curve in early life may have difficulty achieving their peak, as poor bone mineral density can affect everything from our appetite to how efficient our gastrointestinal tract is at absorbing <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6971894/">important nutrients</a> (including calcium). Supplements have a limited effect because our body can only absorb a set amount of any <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8746734/">vitamin or mineral at a time</a>. While it’s possible to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5684300/">limit some of the decline</a> in bone density that naturally happens as we age, some of the choices we make – such as not consuming enough calcium – can accelerate the decline. Biological sex also has a significant impact on our bone health in old age – with post-menopausal women at greater risk of osteoporosis because they <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5643776/">produce less oestrogen</a>, which helps keep the cells that <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3424385">degrade bone</a> in check.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/228321/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/adam-taylor-283950">Adam Taylor</a>, Professor and Director of the Clinical Anatomy Learning Centre, <a href="https://theconversation.com/institutions/lancaster-university-1176">Lancaster University</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

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

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

Heated argument between economy passengers reignites plane etiquette debate

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. The viral video which was originally posted on TikTok and then re-shared on X, has racked up over 8 million views since Thursday. In the video, a frustrated woman was calling out another female passenger for pushing her seat the entire flight, right after they landed. “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. “You seen it. You know she did.” “I’m allowed to put my seat back," she yelled repeatedly. 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.” A few were on the woman's side and praised her for standing up for herself. “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. “She was patient enough to wait till flight landed," they added. “If the seat is reclinable, recline it,” another commented. "What she’s saying is right. The woman has a right to put her seat back without someone kicking it," a third agreed. <blockquote class="twitter-tweet"> 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> — Ian Miles Cheong (@stillgray) <a href="https://twitter.com/stillgray/status/1719881310351863952?ref_src=twsrc%5Etfw">November 2, 2023</a></blockquote> 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. “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. “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. “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. One user understood both sides of the argument, and blamed the airlines for making the seats so cramped. "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. "You don't kick the seat like a baby. Blame the airline, not the person doing what the airline says is fine." Images: Twitter

Extreme weather is landing more Australians in hospital – and heat is the biggest culprit

<a href="https://theconversation.com/profiles/amy-peden-1136424">Amy Peden</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> Hospital admissions for injuries directly attributable to extreme weather events – such as heatwaves, bushfires and storms – have increased in Australia over the past decade. A new <a href="https://www.aihw.gov.au/reports/injury/extreme-weather-injuries/contents/about">report</a> from the Australian Institute of Health and Welfare (AIHW) shows 9,119 Australians were hospitalised for injuries from extreme weather from 2012-22 and 677 people died from these injuries in the decade up to 2021. In 2021-22, there were 754 injury hospitalisations directly related to extreme weather, compared to 576 in 2011-12. Extreme heat is responsible for most weather-related injuries. Exposure to prolonged natural heat can result in physical conditions ranging from mild heat stroke, to organ damage and <a href="https://www.dea.org.au/wp-content/uploads/2021/01/DEA-Fact-Sheet_HeatwavesWEB.pdf">death</a>. As Australia heads into summer with an El Niño, it’s important understand and prepare for the health risks associated with extreme weather. <h2>A spike every three years</h2> Extreme weather-related hospitalisations have spiked at more than 1,000 cases every three years, with the spikes becoming progressively higher. There were: <ul> <li>1,027 injury hospitalisations in 2013–14</li> <li>1,033 in 2016–17</li> <li>1,108 in 2019–20.</li> </ul> <iframe id="vLaas" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/vLaas/1/" width="100%" height="400px" frameborder="0"></iframe> In each of these three years, extreme heat had the biggest impact on hospital admissions and deaths. <iframe id="P03sm" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/P03sm/1/" width="100%" height="400px" frameborder="0"></iframe> Extreme heat accounted for 7,104 injury hospitalisations (78% of all injury hospitalisations) and 293 deaths (43% of all injury deaths) in the ten year period analysed. In 2011-12, there were 354 injury hospitalisations directly related to extreme heat. This rose to 579 by 2021-22. <h2>El Niño and La Niña</h2> Over the past three decades, extreme weather events have increased in <a href="https://www.ipcc.ch/report/ar5/syr/">frequency</a> and <a href="http://www.bom.gov.au/state-of-the-climate/">severity</a>. In Australia, El Niño drives a period of reduced rainfall, warmer temperatures and increased bushfire danger. La Niña, on the other hand, is associated with above average rainfall, cooler daytime temperatures and increased chance of tropical cyclones and flood events. Although similar numbers of heatwave-related hospitalisations occurred in El Niño and La Niña years studied, the number of injuries related to bushfires was higher in El Niño years. During the 2019–20 bushfires, in the week beginning January 5 2020, there were 1,100 more hospitalisations than the previous five-year average, an 11% increase. Although El Niño hasn’t directly been proved as the cause for these three spikes, according to the Bureau of Meteorology, two of the three years (2016-17 and 2019-20) were El Niño summers. And the other year (2013-14) was the warmest neutral year on record at that time. <h2>Regional differences</h2> Exposure to excessive natural heat was the most common cause leading to injury hospitalisation for all the mainland states and territories. From 2019 to 2022, there were 2,143 hospital admissions related to extreme heat, including: <ul> <li>717 patients from Queensland</li> <li>410 from Victoria</li> <li>348 from NSW</li> <li>267 from South Australia</li> <li>266 from Western Australia</li> <li>73 from the Northern Territory</li> <li>23 from the ACT</li> <li>19 from Tasmania.</li> </ul> <figure class="align-center "><img src="https://images.theconversation.com/files/556987/original/file-20231101-27-3c98xm.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/556987/original/file-20231101-27-3c98xm.png?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=632&fit=crop&dpr=1 600w, https://images.theconversation.com/files/556987/original/file-20231101-27-3c98xm.png?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=632&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/556987/original/file-20231101-27-3c98xm.png?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=632&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/556987/original/file-20231101-27-3c98xm.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=794&fit=crop&dpr=1 754w, https://images.theconversation.com/files/556987/original/file-20231101-27-3c98xm.png?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=794&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/556987/original/file-20231101-27-3c98xm.png?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=794&fit=crop&dpr=3 2262w" alt="" /><figcaption><a class="source" href="https://www.aihw.gov.au/reports-data/latest-reports">AIHW National Hospital Morbidity Database</a>, <a class="license" href="http://creativecommons.org/licenses/by/4.0/">CC BY</a></figcaption></figure> The report also includes state and territory data on hospitalisations related to extreme cold and storms. During the ten-year period analysed, there were 773 injury hospitalisations and 242 deaths related to extreme cold. Extreme rain or storms accounted for 348 injury hospitalisations and 77 deaths. From 2019 to 2022, there were 191 hospitalisations related to extreme cold, with Victoria recording the highest number (51, compared to 40 in next-placed NSW). During the same period there were 111 hospitalisations related to rain and storms, with 52 occurring in NSW and 28 in Queensland. <h2>What about for bushfires?</h2> Over the ten-year period studied, there were 894 hospitalisations and 65 deaths related to bushfires. Bushfire-related injury hospitalisations and deaths peaked in 2019–20, an El Niño year with 174 hospitalisations and 35 deaths. The two most common injuries that result from bushfires are smoke inhalation and burns. During the 2019–20 bushfires, in the week beginning 5 January 2020 there were 1,100 more respiratory hospitalisations than the previous five-year average, an 11% increase. The greatest increase in the hospitalisation rate for burns was 30% in the week beginning December 15 2019 — 0.8 per 100,000 persons (about 210 hospitalisations), compared with the previous 5-year average of 0.6 per 100,000 (an average of 155 hospitalisations). <h2>Some people are particularly vulnerable</h2> Anyone can be affected by extreme weather-related injuries but some population groups are more at risk than others. This includes older people, children, people with disabilities, those with pre-existing or chronic health conditions, outdoor workers, and those with greater <a href="https://www.mdpi.com/2071-1050/15/1/813">socioeconomic disadvantage</a>. People in these groups may have reduced capacity to avoid or reduce the health impacts of extreme weather conditions, for example older people taking medication may be less able to regulate their body temperature. “Thermal inequity” includes people living in poor quality housing who have difficulty accessing adequate heating and cooling. For heat-related injuries between 2019–20 and 2021–22, people aged 65 and over were the most commonly admitted to hospital, followed by people aged 25–44. Across age groups, men had higher numbers of heat related injury hospitalisations than women. This difference was most notable among those aged 25-44 and 45-64 years, where over twice as many men were hospitalised due to extreme heat as women. <h2>We still don’t have a full picture</h2> The AIHW data only includes injuries which were serious enough for patients to be admitted to hospital; it doesn’t include cases where patients treated in an emergency department and sent home without being admitted. It includes injuries that were directly attributable to weather-related events but does not include injuries that were indirectly related. For example, it doesn’t include injuries from road traffic accidents that occur due to wet weather, since the primary cause of injury would be recorded as “transport”. Improved surveillance of weather-related injuries could help the health system and the community better prepare for responding to extreme weather conditions. For example, better data aids communities in predicting what resources will be needed during periods of extreme weather. A more complete picture of injuries during weather events could also be used to inform people of actions they can take to protect their own health. Given a predicted hot summer, this could be a matter of life or death.

4 ways to support someone with dementia during extreme heat

Extreme heat and bushfires bring unique challenges for someone with dementia. Bushfires have a significant impact on older people’s mental health. But they generally <a href="https://www.health.act.gov.au/sites/default/files/2023-03/PATH_Impact%20of%202019-20%20Bushfires%20on%20a%20Cohort%20of%20Older%20Adults_REPORT_V3_0.pdf">bounce back</a> quickly. However, for someone with dementia, extreme heat can lead to a <a href="https://www.sciencedirect.com/science/article/pii/S0013935119305110">significant deterioration</a> in their overall health and they may not recover. Emergency evacuations can also be confusing and distressing for a person with dementia, so it is important to think ahead. <h2>Why are people with dementia more at risk?</h2> Dementia can affect the parts of the brain that help <a href="https://academic.oup.com/brain/article/138/11/3360/332653?login=true">regulate</a> our body temperature. Some <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0243665">medications</a> can also increase someone’s sensitivity to heat. Problems with memory and thinking associated with dementia <a href="https://www.alzheimers.org.uk/get-support/daily-living/drinking-hydration">means</a> remembering to drink or communicating you are thirsty can be challenging. Heat can affect everyone’s mood. But if someone with dementia becomes dehydrated this can <a href="https://www.alzdiscovery.org/cognitive-vitality/blog/can-dehydration-impair-cognitive-function">increase</a> confusion and agitation, making it harder for them to know how to cool down. A person with dementia can also wander and become lost, which can be dangerous in extreme heat. <h2>4 ways to support someone with dementia</h2> 1. Avoid dehydration and heatstroke Try to avoid dehydration by encouraging someone to drink throughout the day. It’s better to have <a href="https://pubmed.ncbi.nlm.nih.gov/31769256/">small amounts</a> of liquid regularly instead of a large amount all at once. Little and often will help maximise hydration while avoiding sudden trips to <a href="https://www.betterhealth.vic.gov.au/health/conditionsandtreatments/dementia-continence-issues#causes-of-incontinence-in-people-with-dementia">the bathroom</a>. Try to offer different types of drinks, or ice blocks. Placing drinks in sight can help as a reminder to drink. Choose foods with a high liquid content, such as fruit, salads, cool broths and yoghurt. Look out for <a href="https://www.nia.nih.gov/health/hot-weather-safety-older-adults#:%7E:text=Signs%20of%20heat%20stroke%20are,as%20under%20shade%20or%20indoors.">signs of heatstroke</a>, such as increased confusion beyond what the person would usually experience. Heatstroke may be more difficult to spot in someone living with dementia so it is important to check in when possible and to help them cool down if needed. 2. Cool the home Try to modify their home to make it easier to stay cool. Some air-conditioners have complex settings so make sure the temperature is set appropriately and the person with dementia knows how to use the controls. It is important to keep blinds and curtains shut where possible to reduce heat. However, ensure the <a href="https://www.scie.org.uk/dementia/supporting-people-with-dementia/dementia-friendly-environments/lighting.asp">lighting is adequate</a> to avoid falls. Try to support the person to make suitable clothing choices for the season by having cool, lightweight options easily available. 3. Think about communications early If someone with dementia lives alone, consider how you will maintain contact in an emergency. Some people may not realise many landlines don’t work in a power outage, and of course, mobile phones can’t be recharged. Ensure the person with dementia has access to an <a href="https://www.telstra.com.au/support/category/home-phone/uninterruptible-power-supply">uninterruptable power supply</a>. This can help maintain communication for a few hours in a blackout. 4. Have an evacuation plan In case of fire, flash flooding or severe storm, <a href="https://dementiaresearch.org.au/wp-content/uploads/2017/10/2447_DCRC_Prep_natural_disaster_EBook_5.pdf">have an evacuation plan</a>. If the person with dementia attends a day or respite centre, know their plan too. The situation can change quickly in an emergency, and this can be particularly overwhelming for people with cognitive issues. Understand that someone with dementia may become distressed when their routine is disrupted. So be prepared with some simple activities or comfort items, current medications, and any specific medical information. Stay up-to-date with <a href="http://www.bom.gov.au/">current warnings</a> and act early whenever possible. <h2>We can all help</h2> It’s not just carers of people with dementia who can help. We can all ensure people with dementia stay safe and cool this spring and summer. So remember to check in on your relatives, friends and neighbours or arrange for someone to do so on your behalf.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/213987/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/nikki-anne-wilson-342631">Nikki-Anne Wilson</a>, Postdoctoral Research Fellow, Neuroscience Research Australia (NeuRA), <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

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

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

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

<a href="https://theconversation.com/profiles/josh-ettinger-1302389">Josh Ettinger</a>, <a href="https://theconversation.com/institutions/university-of-oxford-1260">University of Oxford</a> Record-breaking heatwaves are <a href="https://public.wmo.int/en/media/news/simultaneous-heatwaves-hit-northern-hemisphere-summer-of-extremes">sweeping across the northern hemisphere</a>, affecting large parts of southern Europe, the US and China. On July 24, Sicily recorded blistering temperatures <a href="https://www.bbc.com/news/world-europe-66302472">of more than 47.5℃</a> and wildfires are currently <a href="https://www.theguardian.com/world/2023/jul/25/how-bad-are-wildfires-in-greece-what-caused-them-visual-guide-heatwave">tearing through Greece</a>. The heatwaves come as <a href="https://www.reuters.com/graphics/CANADA-WILDFIRE/HISTORIC/znvnzebmavl/">record numbers of fires continue to burn</a> across Canada. A <a href="https://www.bbc.co.uk/news/science-environment-66289489">study by the World Weather Attribution group</a> found that these heatwaves would have been “virtually impossible” without climate change. In fact, the heatwave that is affecting parts of China was made 50 times more likely by global warming. This is exactly what climate scientists have been warning us about for decades – climate change makes many types of extreme weather event <a href="https://www.carbonbrief.org/explainer-what-the-new-ipcc-report-says-about-extreme-weather-and-climate-change/">more likely, more intense and longer lasting</a>. As a PhD researcher examining extreme weather events and climate change communication, I have spent the past four years exploring how extreme weather events may affect the way the public feels, thinks and acts on climate change. One area of interest to researchers is how extreme weather events might reduce the <a href="https://www.sciencedirect.com/science/article/pii/S0272494422000676">“psychological distance”</a> associated with climate change. While climate change can feel abstract and vague, extreme weather is something people can experience firsthand. But <a href="https://iopscience.iop.org/article/10.1088/1748-9326/ab466a/meta">research offers contrasting results</a>. Some studies have found that extreme weather events lead to an <a href="https://www.journals.uchicago.edu/doi/full/10.1017/S0022381612000448?casa_token=dTns6Kvds1AAAAAA%3AkQcleVJ95vJUyh5Pg2vxvFEDbzfR1RsuOI131QCMO0wvdtIiLSVEq4EW6fZYwC7Yhraxj-NB9g">increased belief</a> that human-driven climate change is occurring and <a href="https://link.springer.com/article/10.1007/s10584-016-1837-4">greater support for climate action</a>. Others <a href="https://link.springer.com/article/10.1007/s10584-021-03176-z">find no effects</a> or suggest that these effects are <a href="https://www.sciencedirect.com/science/article/abs/pii/S0959378017309135?via%3Dihub">only temporary</a>. However, <a href="https://www.nature.com/articles/s41467-022-32412-y">we often underestimate</a> how much the public already cares about climate change. In Britain, <a href="https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/1164127/desnz-pat-spring-2023-net-zero-and-climate-change.pdf">just 4% of the public</a> say they are not at all concerned about climate change, while only <a href="https://climatecommunication.yale.edu/about/projects/global-warmings-six-americas/">11% of Americans</a> dismiss the issue. Given that <a href="https://www.pewresearch.org/short-reads/2019/04/18/a-look-at-how-people-around-the-world-view-climate-change/">most people</a> are already concerned about climate change, an important question now is how to shift these existing concerns into action. <a href="https://theconversation.com/how-to-talk-to-your-family-and-friends-about-the-new-ipcc-report-five-tips-from-climate-change-communication-research-202306">Talking about climate change</a> is a powerful way of mobilising climate action, and extreme weather events provide helpful climate conversation starters. We can use these moments as opportunities to <a href="https://journals.sagepub.com/doi/10.1177/20563051231177930">engage our families, friends and communities</a> in discussions about how climate change may relate to these events and <a href="https://drawdown.org/solutions">what we can do about it</a>. So, if you decide to engage people you know in discussions about extreme weather and climate change, here are a few thoughts and guidelines to keep in mind. <h2>1. Listen and share perspectives</h2> <a href="https://www.sciencedirect.com/science/article/abs/pii/S0887618520300773">Extreme weather events can be traumatic</a> and climate change can evoke a wide range of emotional responses. If the person you are talking to is comfortable discussing the topic, ask them about their experiences and observations. Encourage them to tell stories and affirm the validity of their emotional response – whether they are afraid, angry, hopeful or worried. There is no one right way to feel about climate change, so listen to what they have to say and then share your own perspective too. <h2>2. Talk about planning and preparation</h2> When discussing extreme weather events, some people may link their experiences to climate change, while others focus on various local factors that contribute to extreme weather risks. The risks associated with extreme weather arise from a <a href="https://www.ipcc.ch/report/ar6/wg2/chapter/summary-for-policymakers/">combination</a> of factors. These include the weather itself, which can be influenced by climate change, the level of exposure of people and places to extreme weather and the vulnerability of those to harm. Climate change, for instance, can affect the frequency, intensity and duration of wildfires. But emergency responses, evacuation procedures, firefighting and healthcare systems are crucially important to reduce risks. There are also significant equity and justice implications of extreme weather as different populations are <a href="https://link.springer.com/article/10.1007/s41885-020-00060-5">affected disproportionally</a>. It’s also important to bear in mind that while climate change affects many extreme weather events, it <a href="https://www.carbonbrief.org/climate-change-not-the-main-driver-of-madagascar-food-crisis-scientists-find/">does not necessarily affect every instance</a>. Weather systems are complex and there are <a href="https://theconversation.com/heres-why-climate-change-isnt-always-to-blame-for-extreme-rainfall-206958">meteorological processes</a> that scientists are still trying to understand. We also need to make sure the roles of local planning and preparation in minimising the impact of these events are not overlooked. <h2>3. Challenge arguments about politicising the weather</h2> In May 2023, Republican governor of Florida, Ron DeSantis, dismissed concerns about global warming by claiming that he rejects the <a href="https://www.independent.co.uk/news/world/americas/us-politics/desantis-climate-change-fox-news-b2346211.html">“politicisation of the weather”</a>. Ontario premier, Doug Ford, recently <a href="https://www.cbc.ca/news/canada/toronto/ontario-climate-change-forest-fires-politics-ford-stiles-1.6869071">made a similar argument</a> about Canada’s wildfires. In conversations, it’s possible that someone might accuse you too of “politicising” the weather. You can (respectfully) push back against this claim. This argument is a <a href="https://www.cambridge.org/core/journals/global-sustainability/article/discourses-of-climate-delay/7B11B722E3E3454BB6212378E32985A7">discourse of climate delay</a>. Rather than denying the existence of human-driven climate change, climate delay discourses try to shut down climate discussions and cast doubt on the need to act very quickly. These arguments disingenuously assert that acting on climate is too expensive, too late or that someone else should take care of it – and they are <a href="https://theconversation.com/climate-change-multi-country-media-analysis-shows-scepticism-of-the-basic-science-is-dying-out-198303">becoming increasingly common</a>. If we shouldn’t discuss climate change when extreme weather occurs, then when is the right time? If we want to protect lives, we need to talk about – and act upon – the risks associated with extreme weather events and the disasters they can cause. If talking about climate change politicises the weather, so be it. The politics of climate denial and delay affected this summer’s weather, and our current decisions will shape our planet for thousands of years. The science is clear. Act now or face increasingly dire consequences.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/210412/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/josh-ettinger-1302389">Josh Ettinger</a>, Doctoral researcher, School of Geography and the Environment, <a href="https://theconversation.com/institutions/university-of-oxford-1260">University of Oxford</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

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

<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> 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. 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>. <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. 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. <h2>How does this ban help?</h2> 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. 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. The government appears to be offering wide support to ensure these changes happen, but this will need to be monitored closely. 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. 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. 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. <h2>Challenges of change must be managed</h2> 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. 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). 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. In addition, existing housing may face building quality and performance issues. Some may require electrical wiring upgrades as part of the transition. 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. Consumer education and modifications to appliances and buildings may be needed to increase acceptance and avoid backlash. 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. 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. 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. Continued planning reforms are also essential to ensure environmentally sustainable development of housing and communities. Other urgent priorities include urban cooling and greening, and <a href="https://theconversation.com/turning-the-housing-crisis-around-how-a-circular-economy-can-give-us-affordable-sustainable-homes-208745">circular economy approaches</a> to reduce the material and waste impacts of housing and thus the carbon that goes into building and running homes.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/210649/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/trivess-moore-12580">Trivess Moore</a>, Senior Lecturer, School of Property, Construction and Project Management, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a>; <a href="https://theconversation.com/profiles/alan-pears-52">Alan Pears</a>, Senior Industry Fellow, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a>, and <a href="https://theconversation.com/profiles/joe-hurley-157161">Joe Hurley</a>, Associate Professor, Sustainability and Urban Planning, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

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>. 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. 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. 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>. 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. <h2>What will climate change do to mass tourism?</h2> 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. 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. 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. 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>. 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. 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. <h2>What does this mean for countries reliant on tourism?</h2> 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. 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>. 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. 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. 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. 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. <h2>Mountains not beaches: future tourism may look a lot different</h2> 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. 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. 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>. 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. The future of tourism is going to be very different. <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/210282/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/susanne-becken-90437">Susanne Becken</a>, Professor of Sustainable Tourism, Griffith Institute for Tourism, <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> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

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

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