‘A woman is not a baby-making machine’: a brief history of South Korea’s 4B movement – and why it’s making waves in America

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/ming-gao-1496188">Ming Gao</a>, <a href="https://theconversation.com/institutions/australian-catholic-university-747">Australian Catholic University</a></em></p> <p>In South Korea, a growing number of young women are rejecting societal expectations of marriage, motherhood and heterosexual relationships, known as the “4B Movement” or the “4 Nos”.</p> <p>The “B” is a homophone for the Korean word <em>bi</em> (비/非), meaning “no”, representing the movement’s four principles: <em>bihon</em> (no marriage), <em>bichulsan</em> (no childbirth), <em>biyeonae</em> (no dating) and <em>bisekseu</em> (no sex).</p> <p>By refusing to marry, have children, engage in romance, or participate in sexual relationships with men, 4B feminists seek to redefine their lives outside the confines of traditional gender roles.</p> <p>In the wake of the reelection of Donald Trump, there has been <a href="https://www.abc.net.au/news/2024-11-10/donald-trump-win-4b-movement-male-supremacists-make-threats/104575732">increased interest</a> in the 4B movement from women in the United States.</p> <p>But what is the 4B Movement, where did it come from, and how is it reshaping the feminist landscape in South Korea and beyond?</p> <h2>Challenges facing young women</h2> <p>The 4B Movement reflects <a href="https://www.khan.co.kr/national/national-general/article/202004140938001">a broader dissatisfaction</a> among young South Korean women who face instability of housing, digital sexual violence, economic disparities and cultural pressures.</p> <p>It emerged in the mid- to late-2010s, following a surge of interest in feminism in South Korea, and spread primarily through women’s online communities.</p> <p>The roots of the 4B Movement lie in South Korea’s rapid economic transformation and the subsequent challenges it posed for younger generations of the 2000s.</p> <p>For young women, economic insecurity is compounded by systemic gender inequality. South Korea <a href="https://www.straitstimes.com/asia/east-asia/south-korea-s-gender-pay-gap-worst-in-oecd">consistently ranks</a> worst in the OECD for the gender wage gap, and social mobility remains limited.</p> <p>Against this backdrop, traditional life paths – marriage, childbearing and homemaking – have become less appealing.</p> <p>Living an alternative life without men emerged as a radical strategy for young digital feminists to challenge the rigid patriarchy in South Korea.</p> <p>The <a href="https://www.khan.co.kr/national/national-general/article/202405172212001">senseless killing</a> in 2016 of a woman in a train station toilet by a man in Seoul shocked the nation and fuelled the movement. Online platforms became spaces where women could share their frustrations, critique patriarchal norms and organise protests.</p> <p>During this period communities like radical feminist online groups gained traction. Among these was the <em><a href="https://www.bbc.com/korean/news-44329328">Tal-Corset</a></em> (escape the corset) movement, which encouraged women to reject societal beauty standards by foregoing makeup, cosmetic surgery and restrictive clothing.</p> <p>The 4B Movement built on this momentum, targeting not only beauty standards but the very institutions that sustain patriarchy.</p> <p>It collectively challenges the notion that women’s value lies in their ability to support men and sustain the family unit.</p> <h2>‘A woman is not a baby-making machine’</h2> <p>The birth rate in South Korea ranks among the <a href="https://worldpopulationreview.com/country-rankings/birth-rate-by-country">lowest in the world</a>. The government has long viewed this as a national crisis. Policies such as subsidised housing for newlyweds and tax incentives for families have sought to encourage marriage and childbearing.</p> <p>In 2016, the government launched a national <a href="https://www.womennews.co.kr/news/articleView.html?idxno=248514">pink birth map</a> visualising the number of women of reproductive age in each district. It sparked outrage. Women criticised it as reducing them to reproductive tools, proclaiming, “<a href="https://www.nocutnews.co.kr/news/4713565">my womb is not national property</a>” and “<a href="https://www.youtube.com/watch?v=6FsEWD1bi3E">a woman is not a baby-making machine</a>”.</p> <p>For many 4B feminists, these policies represent a stark example of how the state prioritises population growth over women’s autonomy. In response, the movement frames its rejection of marriage and motherhood as an act of political resistance.</p> <p>As one <a href="https://www.womennews.co.kr/news/articleView.html?idxno=111598">protest slogan</a> declared: “End population policies! Stop blaming women”.</p> <h2>Living on their own terms</h2> <p>Despite its growing influence, the 4B Movement faces significant challenges.</p> <p>The radical principles have sparked backlash, with critics labelling participants as selfish or anti-social. Swearing off men as a form of protest against patriarchal structures and traditional marital norms is sometimes (mis)interpreted as implicitly favouring <a href="https://brunch.co.kr/brunchbook/radsview2">lesbianism</a>, given its stance against heterosexual relationships.</p> <p>The movement has also attracted negative political attention. <a href="https://www.khan.co.kr/national/national-general/article/202004140938001">Lee Seung-cheon</a>, a 58-year-old Democratic Party candidate, pledged to introduce “measures to reject the 4B Movement” as part of his policy campaign in 2020.</p> <p>Yet 4B feminists remain steadfast in their vision of a future where women can live on their own terms. Their rejection of traditional life paths is not a retreat into isolation but an attempt to create new ways of being free from patriarchal constraints.</p> <p>As one participant noted, rejecting marriage allows women to envision futures beyond societal deadlines like “<a href="https://brunch.co.kr/@404homealone/34">a woman’s age has an expiration date</a>”.</p> <h2>An international movement</h2> <p>The 4B Movement’s radical critique of patriarchy has resonated internationally.</p> <p>4B Movement ideas are starting to strike a chord in the US. The movement’s core principles align with broader feminist critiques of patriarchy and capitalism, which have intensified in response to political developments such as Trump’s rhetoric and debates over reproductive rights.</p> <p>In the US, Trump’s presidency (and now his return) has been a flashpoint for feminist activism. Policies restricting access to abortion, coupled with an increase in conservative rhetoric around women’s rights, have galvanised movements that resist patriarchal structures.</p> <p>For American feminists, the 4B Movement offers a framework for resistance that goes beyond economic precarity. It provides a roadmap for rejecting political conflicts, focusing on reclaiming agency by prioritising autonomy over their own bodies and rights.</p> <p>6B4T is inspired by the 4B Movement and has gained particular attention <a href="https://weibo.com/1263977197/KaFZGjoG4">in China</a>. This version incorporates additional principles, including rejecting consumerism and fostering mutual aid among unmarried women.</p> <p>The spread of 4B ideas across Asia and beyond highlights the universality of feminist struggles. As the movement continues to evolve, its impact extends beyond South Korea, sparking conversations about gender, autonomy and the future of feminism.</p> <p>Whether embraced or contested, the 4B Movement forces society to confront uncomfortable truths about the cost of sustaining patriarchy – and perhaps the possibilities of living without it.</p> <hr /> <p><em>Correction: 6B4T is inspired by the 4B movement and gained attention in China; it did not originate in China.</em><!-- Below is The Conversation's page counter tag.

Teacher's wild salary sparks heated debate

<p>A teacher's hefty salary has sparked a major debate online, with some people arguing that some educators are "extremely overpaid". </p> <p>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. </p> <p>“I’m a teacher and I make just north of $160,000,” he revealed.</p> <p>“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."</p> <p>“School holidays are always good. But when you are working, you’re doing a lot of after hours and things like that.</p> <p>“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."</p> <p>“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."</p> <p>He said, “But you gotta follow your passion first.”</p> <p>The video racked up hundreds of comments, with many stunned at the man’s salary.</p> <p>“There’s no way,” one said, with another adding, “I am in the wrong profession.”</p> <p>In another clip from Getahead, a different woman was quizzed about her salary and it is revealed she is also a teacher.</p> <p>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."</p> <p>While many commenters were stunned by the significant salaries, there were some that even went as far as to claim teachers were being “overpaid”. </p> <p>“Teachers are extremely overpaid,” one claimed. “The most they should be paid is $30k – $40k.”</p> <p>“$110k for a schoolteacher, at this point we are handing out money,” another said.</p> <p>“If they are earning that much money why are they all saying they need more?” another asked, “That’s an excellent wage.”</p> <p>Other teachers sounded shocked at these figures, with many saying they were not making anywhere near that amount.</p> <p>“That’s not close to average, I’m a maths and science teacher at a high school and I earn $84k,” one shared.</p> <p>“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.</p> <p><em>Image credits: TikTok</em></p>

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

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

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

<div class="theconversation-article-body"><em><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></em></p> <p>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>.</p> <p>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.</p> <p>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.</p> <p>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.</p> <h2>Ageing adds urgency to greening</h2> <p>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.</p> <figure class="align-right zoomable"></figure> <p>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.</p> <p>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.</p> <p>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.</p> <h2>What about aged care?</h2> <p>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.</p> <p>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.</p> <p>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.</p> <p>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.</p> <h2>What has our research found?</h2> <p>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.</p> <p>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.</p> <p>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.</p> <p>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.</p> <p>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.<!-- Below is The Conversation's page counter tag.

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

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

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/martin-jucker-379172">Martin Jucker</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a></em></p> <p>Australia’s south and east have seen <a href="https://theconversation.com/southern-australia-is-freezing-how-can-it-be-so-cold-in-a-warming-climate-233977">freezing temperatures</a> and <a href="https://www.theguardian.com/australia-news/article/2024/jul/29/australia-winter-weather-forecast-east-coast-colder-records">wild weather</a> this winter. At the same time, the continent as a whole – and the globe – have <a href="https://www.abc.net.au/news/2024-08-03/australia-suffers-cold-winter-weather-despite-mild-forecast/104176284">continued to warm</a>.</p> <p>What’s going on? As ever, it’s hard to pinpoint a single cause for weather events. But a key player is likely an event unfolding high above Antarctica, which itself may have been triggered by a heatwave at surface level on the frozen continent.</p> <p>Here’s what’s happening – and what it might mean for the rest of this year’s weather.</p> <h2>When the stratosphere heats up</h2> <p>Out story begins in the cold air over Antarctica. July temperatures in the stratosphere, the layer of air stretching between altitudes of around 10 and 50 kilometres, are typically around –80°C.</p> <p>The winds are also very strong, averaging about 300 kilometres per hour in winter. These cold, fast winds loop around above the pole in what is called the <a href="https://sites.krieger.jhu.edu/waugh/research/polarvortex">stratospheric polar vortex</a>.</p> <p>Occasionally, persistent high air pressure in the lower atmosphere can influence large-scale waves that extend around the globe and up into the stratosphere. There they cause the strong winds to slow down, and the air high above the pole to become much warmer than normal.</p> <p>In extreme situations the stratospheric winds can completely break down, in what is called a “sudden stratospheric warming” event. These events occur every few years in the northern hemisphere, but only one has ever been observed in the south, in 2002 (though another <a href="https://theconversation.com/the-air-above-antarctica-is-suddenly-getting-warmer-heres-what-it-means-for-australia-123080">almost happened in 2019</a>).</p> <h2>Pushing polar weather our way</h2> <p>Once the polar vortex is disturbed, it can in turn influence the weather at the surface by steering weather systems from the Southern Ocean towards the Equator. However, this is a slow process.</p> <p>The impact at the surface may not be felt until <a href="https://doi.org/10.1175/JCLI-D-22-0425.1">a few weeks or even months</a> after the initial weakening of the stratospheric polar vortex. Once it begins, the stratospheric influence can prevail for more weeks or months, and helps meteorologists make <a href="https://doi.org/10.5194/acp-22-2601-2022">long-range weather forecasts</a>.</p> <p>In climate science terms, the weak stratospheric winds put an atmospheric system called the <a href="http://www.bom.gov.au/climate/sam/">Southern Annular Mode</a> into a negative phase. The main effect of this on surface weather is to bring westerly winds further north.</p> <p>In winter, this means polar air outbreaks can reach places like Sydney more easily. As a result, we see more <a href="https://doi.org/10.1175/JCLI4134.1">rain over much of southern Australia</a>, and snowfall in alpine regions. In spring and summer it means westerly winds blow over the continent before reaching the east coast, bringing warm and dry air to southeastern Australia.</p> <p>The exact impact of a weaker polar vortex depends on how much and for how long the weather systems are being pushed further northward. It will also depend on other weather influencers such as El Niño and the Indian Ocean Dipole.</p> <h1>This winter’s weirdness</h1> <p>Unpicking exactly why any weather event occurs is tricky at the moment, because global weather has been absolutely crazy over the past 12 months or so. Global temperatures are <a href="https://theconversation.com/we-just-blew-past-1-5-degrees-game-over-on-climate-not-yet-213364">much higher than usual</a>, which is making unusual weather very common.</p> <p>But there are indications that the stratosphere is having some influence on our weather this winter.</p> <p>The stratospheric polar vortex started to warm in mid-July, and is about 20°C warmer than the long-term average. At the time of writing, the winds slowed down to about 230 kilometres per hour, 70 kilometres per hour slower than average.</p> <p>These numbers mean that, technically, the event does not qualify as a sudden stratospheric warming. However, further warming may still occur.</p> <p>If we look at how southern hemisphere winds have evolved in the past few weeks, we see a pattern which looks like what we would expect from a sudden stratospheric warming.</p> <p>First, we see warming in the stratosphere which is <a href="https://doi.org/10.1029/2021GL095270">at first accompanied by a poleward shift of weather systems</a>.</p> <p>The stratosphere’s influence then propagates downward and seems to <a href="https://doi.org/10.1175/JCLI-D-22-0425.1">induce many weeks</a> of weather systems shifted towards the equator.</p> <p>This coincides with the period of cold and rainy weather along Australia’s east coast in late July and the beginning of August. Forecasts suggest the Southern Annular Mode will be a long way from normal conditions in the first half of August – four standard deviations below average, which is extremely rare.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/611211/original/file-20240804-19-sp862a.png?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/611211/original/file-20240804-19-sp862a.png?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/611211/original/file-20240804-19-sp862a.png?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=300&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/611211/original/file-20240804-19-sp862a.png?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=300&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/611211/original/file-20240804-19-sp862a.png?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=300&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/611211/original/file-20240804-19-sp862a.png?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=377&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/611211/original/file-20240804-19-sp862a.png?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=377&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/611211/original/file-20240804-19-sp862a.png?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=377&amp;fit=crop&amp;dpr=3 2262w" alt="Diagram showing atmospheric warming and winds" /></a><figcaption><span class="caption">How initial warming high in the stratosphere ends up changing winds near the surface and pushing polar weather further north.</span> <span class="attribution"><a class="source" href="https://stratobserve.com">Z.D. Lawrence / StratObserve / Annotated by Martin Jucker</a></span></figcaption></figure> <h1>A surface disturbance</h1> <p>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.</p> <p>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>.</p> <p>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.</p> <h1>What should we expect for the rest of the year?</h1> <p>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.</p> <p>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.</p> <p>The seasonal forecasting models from the European Centre for Medium Range Weather Forecasts <a href="https://x.com/drahbutler/status/1819142206348759170?s=46&amp;t=sayfGwpo3_s310BwYpcdcQ">seem to favour this second scenario</a>.<!-- End of code.

<p>The city of Alice Springs has been plunged into a three-night curfew after a wave of violence that saw four police officers allegedly attacked. </p> <p>Northern Territory Police Commissioner Michael Murphy declared the curfew on Monday, which will prevent people of all ages going into the city centre between 10pm and 6am over the next three nights without good reason.</p> <p>"Some of those reasons are if you're fleeing from domestic violence, if you're visiting family, if you have to care for someone, if you're here for employment purposes, if you go into a fast food restaurant or some lawful purpose," Murphy said.</p> <p>He said the curfew area would cover "Anzac Hill, Schwarz Crescent, down to the hospital, from the Stuart Highway across to Leichhardt and Stott Terrace".</p> <p>The curfew is a result of a crime-ridden weekend, where several incidents of violent crime allegedly took place. </p> <p>In the early hours of Sunday morning, a group of four off-duty police officers were allegedly assaulted by a group of 20 young men, while another officer was allegedly run over by a drunk driver outside a bottle shop.</p> <p>"The offending in Alice Springs over the last few days has been unacceptable," NT Chief Minister Eva Lawler said.</p> <p>"The curfew will provide police extra powers to get on top of the situation on the ground in Alice Springs."</p> <p>Commissioner Murphy said he will consider requesting an extension of the curfew if required.</p> <p>"If there is a continuation of harmful conduct, which I hope there is not, we apply some measures now and use the community to help us we should see a turnaround," he said.</p> <p>Lawler said she believed the curfew would be an effective "circuit breaker", but Swinburne University criminology expert Dr Joel McGregor said longer-term measures were required for broader change in the region.</p> <p>"To address any crime problem, interventions that lead to long-term behaviour change are required," he said.</p> <div>"While the Northern Territory curfew may be stopping crimes being perpetuated during the evening, it should not be thought of as a solution to the problems the state is facing."</p> <p><em>Image credits: Shutterstock</em></p> </div>

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

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

Cafe targeted online for charging customer a "heating fee"

<p>A cafe in Melbourne has copped a wave of backlash online after allegedly charging a customer to heat up his muffin for breakfast. </p> <p>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.</p> <p>His post went viral with hundreds of people slamming café etiquette and urging him to go to the ACCC.</p> <p>"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.</p> <p>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.</p> <p>They also said the customer could have simply solved the issue in person rather than blasting them online.</p> <p>"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"><em>Daily Mail Australia</em></a>.</p> <p>"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."</p> <p>The original post racked up more than 870 comments before it was deleted, and more than 1,000 reactions.</p> <p>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. </p> <p>"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.</p> <p>The cafe responded to the growing backlash online by announcing their muffins would be free on Tuesday.</p> <p class="mol-para-with-font" style="margin: 0px 0px 16px; padding: 0px; min-height: 0px;"><em>Image credits: Facebook / Shutterstock </em></p>

What are the four waves of feminism? And what comes next?

<p><a href="https://theconversation.com/profiles/sharon-crozier-de-rosa-122804">S<em>haron Crozier-De Rosa</em></a><em>, <a href="https://theconversation.com/institutions/university-of-wollongong-711">University of Wollongong</a></em></p> <p>In Western countries, feminist history is generally packaged as a story of “waves”. The so-called first wave lasted from the mid-19th century to 1920. The second wave spanned the 1960s to the early 1980s. The third wave began in the mid-1990s and lasted until the 2010s. Finally, some say we are experiencing a fourth wave, which began in the mid-2010s and continues now.</p> <p>The first person to use “waves” was journalist Martha Weinman Lear, in her 1968 New York Times article, <a href="https://www.nytimes.com/1968/03/10/archives/the-second-feminist-wave.html">The Second Feminist Wave</a>, demonstrating that the women’s liberation movement was another <a href="https://www.vox.com/2018/3/20/16955588/feminism-waves-explained-first-second-third-fourth">“new chapter</a> in a grand history of women fighting together for their rights”. She was responding to anti-feminists’ framing of the movement as a “<a href="https://www.vox.com/2018/3/20/16955588/feminism-waves-explained-first-second-third-fourth">bizarre historical aberration</a>”.</p> <p><a href="https://www.journals.uchicago.edu/doi/abs/10.1086/718868">Some feminists</a> criticise the usefulness of the metaphor. Where do feminists who preceded the first wave sit? For instance, Middle Ages feminist writer <a href="https://blogs.loc.gov/bibliomania/2023/08/30/christine-de-pizan/">Christine de Pizan</a>, or philosopher <a href="https://plato.stanford.edu/entries/wollstonecraft/">Mary Wollstonecraft</a>, author of <a href="https://www.penguin.com.au/books/a-vindication-of-the-rights-of-woman-9780141441252">A Vindication of the Rights of Woman</a> (1792).</p> <p>Does the metaphor of a single wave <a href="https://www.vox.com/2018/3/20/16955588/feminism-waves-explained-first-second-third-fourth">overshadow</a> the complex variety of feminist concerns and demands? And does this language exclude the <a href="https://www.journals.uchicago.edu/doi/abs/10.1086/718868">non-West</a>, for whom the “waves” story is meaningless?</p> <p>Despite these concerns, countless feminists <a href="https://www.researchgate.net/publication/317322421_Finding_a_Place_in_History_The_Discursive_Legacy_of_the_Wave_Metaphor_and_Contemporary_Feminism">continue to use</a> “waves” to explain their position in relation to previous generations.</p> <h2>The first wave: from 1848</h2> <p>The first wave of feminism refers to the campaign for the vote. It began in the United States in 1848 with the <a href="https://www.loc.gov/exhibitions/women-fight-for-the-vote/about-this-exhibition/seneca-falls-and-building-a-movement-1776-1890/">Seneca Falls Convention</a>, where 300 gathered to debate Elizabeth Cady Stanton’s Declaration of Sentiments, outlining women’s inferior status and demanding suffrage – or, the right to vote.</p> <p>It continued over a decade later, in 1866, in Britain, with the presentation of a <a href="https://www.parliament.uk/about/living-heritage/transformingsociety/electionsvoting/womenvote/parliamentary-collections/1866-suffrage-petition/presenting-the-petition/">suffrage petition</a> to parliament.</p> <p>This wave ended in 1920, when women were granted the right to vote in the US. (Limited women’s suffrage had been introduced in Britain two years earlier, in 1918.) First-wave activists believed once the vote had been won, women could use its power to enact other much-needed reforms, related to property ownership, education, employment and more.</p> <p>White leaders dominated the movement. They included longtime president of the the International Woman Suffrage Alliance <a href="https://cattcenter.iastate.edu/home/about-us/carrie-chapman-catt/">Carrie Chapman Catt</a> in the US, leader of the militant Women’s Social and Political Union <a href="https://www.britannica.com/biography/Emmeline-Pankhurst">Emmeline Pankhurst</a> in the UK, and <a href="https://adb.anu.edu.au/biography/spence-catherine-helen-4627">Catherine Helen Spence</a> and <a href="https://adb.anu.edu.au/biography/goldstein-vida-jane-6418">Vida Goldstein</a> in Australia.</p> <p>This has tended to obscure the histories of non-white feminists like evangelist and social reformer <a href="https://www.britannica.com/biography/Sojourner-Truth">Sojourner Truth</a> and journalist, activist and researcher <a href="https://www.womenshistory.org/education-resources/biographies/ida-b-wells-barnett">Ida B. Wells</a>, who were fighting on multiple fronts – including anti-slavery and anti-lynching –  as well as feminism.</p> <h2>The second wave: from 1963</h2> <p>The second wave coincided with the publication of US feminist Betty Friedan’s <a href="https://www.penguin.com.au/books/the-feminine-mystique-9780141192055">The Feminine Mystique</a> in 1963. Friedan’s “<a href="https://www.smithsonianmag.com/smithsonian-institution/powerful-complicated-legacy-betty-friedans-feminine-mystique-180976931/">powerful treatise</a>” raised critical interest in issues that came to define the women’s liberation movement until the early 1980s, like workplace equality, birth control and abortion, and women’s education.</p> <p>Women came together in “consciousness-raising” groups to share their individual experiences of oppression. These discussions informed and motivated public agitation for <a href="https://www.berghahnbooks.com/title/HaeberlenPolitics">gender equality and social change</a>. Sexuality and gender-based violence were other prominent second-wave concerns.</p> <p>Australian feminist Germaine Greer wrote <a href="https://www.harpercollins.com.au/9780007205011/the-female-eunuch/">The Female Eunuch</a>, published in 1970, which <a href="https://theconversation.com/friday-essay-the-female-eunuch-at-50-germaine-greers-fearless-feminist-masterpiece-147437">urged women to</a> “challenge the ties binding them to gender inequality and domestic servitude” – and to ignore repressive male authority by exploring their sexuality.</p> <p>Successful lobbying saw the establishment of refuges for women and children fleeing domestic violence and rape. In Australia, there were groundbreaking political appointments, including the world’s first Women’s Advisor to a national government (<a href="https://www.nma.gov.au/audio/landmark-women/transcripts/landmark-women-elizabeth-reid-181013.mp3-transcript">Elizabeth Reid</a>). In 1977, a <a href="https://www.whitlam.org/women-and-whitlam">Royal Commission on Human Relationships</a> examined families, gender and sexuality.</p> <p>Amid these developments, in 1975, Anne Summers published <a href="https://theconversation.com/damned-whores-and-gods-police-is-still-relevant-to-australia-40-years-on-mores-the-pity-47753">Damned Whores and God’s Police</a>, a scathing historical critique of women’s treatment in patriarchal Australia.</p> <p>At the same time as they made advances, so-called women’s libbers managed to anger earlier feminists with their distinctive claims to radicalism. Tireless campaigner <a href="https://adb.anu.edu.au/biography/rich-ruby-sophia-14202">Ruby Rich</a>, who was president of the Australian Federation of Women Voters from 1945 to 1948, responded by declaring the only difference was her generation had called their movement “<a href="https://nla.gov.au/nla.obj-296328435/findingaid">justice for women</a>”, not “liberation”.</p> <p>Like the first wave, mainstream second-wave activism proved largely irrelevant to non-white women, who faced oppression on intersecting gendered and racialised grounds. African American feminists produced their own critical texts, including bell hooks’ <a href="https://www.routledge.com/Aint-I-a-Woman-Black-Women-and-Feminism/hooks/p/book/9781138821514">Ain’t I a Woman? Black Women and Feminism</a> in 1981 and Audre Lorde’s <a href="https://www.penguinrandomhouse.com/books/198292/sister-outsider-by-audre-lorde/">Sister Outsider</a> in 1984.</p> <h2>The third wave: from 1992</h2> <p>The third wave was announced in the 1990s. The term is popularly attributed to Rebecca Walker, daughter of African American feminist activist and writer <a href="https://alicewalkersgarden.com/about/">Alice Walker</a> (author of <a href="https://www.hachette.com.au/alice-walker/the-color-purple-now-a-major-motion-picture-from-oprah-winfrey-and-steven-spielberg">The Color Purple</a>).</p> <p>Aged 22, Rebecca proclaimed in a 1992 Ms. magazine <a href="https://web.archive.org/web/20200404030632/http:/heathengrrl.blogspot.com/2007/02/becoming-third-wave-by-rebecca-walker.html">article</a>: “I am not a post-feminism feminist. I am the Third Wave.”</p> <p>Third wavers didn’t think gender equality had been more or less achieved. But they did share <a href="https://journals.sagepub.com/doi/10.1177/1464700119842555">post-feminists</a>’ belief that their foremothers’ concerns and demands were obsolete. They argued women’s experiences were now shaped by <a href="https://www.tandfonline.com/doi/full/10.1080/14680777.2016.1190046">very different</a> political, economic, technological and cultural conditions.</p> <p>The third wave has been described as “an <a href="https://www.smh.com.au/lifestyle/beauty/meet-the-woman-who-coined-the-term-third-wave-feminism-20180302-p4z2mw.html">individualised feminism</a> that can not exist without diversity, sex positivity and intersectionality”.</p> <p>Intersectionality, <a href="https://chicagounbound.uchicago.edu/cgi/viewcontent.cgi?article=1052&amp;context=uclf">coined</a> in 1989 by African American legal scholar Kimberlé Crenshaw, recognises that people can experience intersecting layers of oppression due to race, gender, sexuality, class, ethnicity and more. Crenshaw notes this was a “lived experience” before it was a term.</p> <p>In 2000, Aileen Moreton Robinson’s <a href="https://www.uqp.com.au/books/talkin-up-to-the-white-woman-indigenous-women-and-feminism-20th-anniversary-edition">Talkin’ Up to the White Woman: Indigenous Women and Feminism</a> expressed Aboriginal and Torres Strait Islander women’s frustration that white feminism did not adequately address the legacies of dispossession, violence, racism, and sexism.</p> <p>Certainly, the third wave accommodated <a href="https://paromitapain.com/wp-content/uploads/2019/12/10.10072F978-3-319-72917-6.pdf#page=112%22">kaleidoscopic views</a>. Some scholars claimed it “grappled with fragmented interests and objectives” – or micropolitics. These included ongoing issues such as sexual harassment in the workplace and a scarcity of women in positions of power.</p> <p>The third wave also gave birth to the <a href="https://www.nme.com/blogs/nme-blogs/brief-history-riot-grrrl-space-reclaiming-90s-punk-movement-2542166">Riot Grrrl</a> movement and “girl power”. Feminist punk bands like <a href="https://bikinikill.com/about/">Bikini Kill</a> in the US, <a href="https://www.theguardian.com/music/2022/nov/28/pussy-riot-beaten-jailed-exiled-taunting-putin">Pussy Riot</a> in Russia and Australia’s <a href="https://www.vice.com/en/article/mbknev/little-ugly-girls-tractor-album-single-premiere-2018">Little Ugly Girls</a> sang about issues like homophobia, sexual harassment, misogyny, racism, and female empowerment.</p> <p>Riot Grrrl’s <a href="https://www.historyisaweapon.com/defcon1/riotgrrrlmanifesto.html">manifesto</a> states “we are angry at a society that tells us Girl = Dumb, Girl = Bad, Girl = Weak”. “Girl power” was epitomised by Britain’s more sugary, phenomenally popular Spice Girls, who were accused of peddling “<a href="https://www.theguardian.com/tv-and-radio/2021/sep/14/spice-girls-how-girl-power-changed-britain-review-fabulous-and-intimate">‘diluted feminism’ to the masses</a>”.</p> <figure><iframe src="https://www.youtube.com/embed/tAbhaguKARw?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">Riot Grrrrl sang about issues like homophobia, sexual harassment, misogyny and racism.</span></figcaption></figure> <h2>The fourth wave: 2013 to now</h2> <p>The fourth wave is epitomised by “<a href="https://vc.bridgew.edu/jiws/vol25/iss2/10/">digital or online feminism</a>” which gained currency in about <a href="https://www.vox.com/2018/3/20/16955588/feminism-waves-explained-first-second-third-fourth">2013</a>. This era is marked by mass online mobilisation. The fourth wave generation is connected via new communication technologies in ways that were not previously possible.</p> <p>Online mobilisation has led to spectacular street demonstrations, including the #metoo movement. #Metoo was first founded by Black activist <a href="https://www.womenshistory.org/education-resources/biographies/tarana-burke">Tarana Burke</a> in 2006, to support survivors of sexual abuse. The hashtag #metoo then went viral during the 2017 Harvey Weinstein <a href="https://www.npr.org/2022/10/28/1131500833/me-too-harvey-weinstein-anniversary">sexual abuse scandal</a>. It was used at least <a href="https://www.sciencedirect.com/science/article/abs/pii/S0747563221002193">19 million times</a> on Twitter (now X) alone.</p> <p>In January 2017, the <a href="https://www.womensmarch.com/">Women’s March</a> protested the inauguration of the decidedly misogynistic Donald Trump as US president. <a href="https://www.britannica.com/event/Womens-March-2017">Approximately 500,000</a> women marched in Washington DC, with demonstrations held simultaneously in <a href="https://www.routledge.com/Remembering-Womens-Activism/Crozier-De-Rosa-Mackie/p/book/9781138794894">81 nations</a> on all continents of the globe, even Antarctica.</p> <p>In 2021, the <a href="https://catalogue.nla.gov.au/catalog/8564388">Women’s March4Justice</a> saw some 110,000 women rallying at more than 200 events across Australian cities and towns, protesting workplace sexual harassment and violence against women, following high-profile cases like that of Brittany Higgins, revealing <a href="https://www.theguardian.com/australia-news/2023/nov/29/brittany-higgins-bruce-lehrmann-defamation-trial-evidence-stand-rape-allegations-liberal-party-ntwnfb#:%7E:text=Bruce%20Lehrmann%20has%20brought%20a,Wilkinson%20are%20defending%20the%20case.">sexual misconduct</a> in the Australian houses of parliament.</p> <p>Given the prevalence of online connection, it is not surprising fourth wave feminism has reached across geographic regions. The Global Fund for Women <a href="https://www.globalfundforwomen.org/movements/me-too/">reports</a> that #metoo transcends national borders. In China, it is, among other things, #米兔 (translated as “<a href="https://www.ft.com/content/61903744-9540-11e8-b67b-b8205561c3fe">rice bunny</a>”, pronounced as “mi tu”). In Nigeria, it’s <a href="https://www.youtube.com/watch?v=we-F0Gi0Lqs">#Sex4Grades</a>. In Turkey, it’s #<a href="https://ahvalnews.com/sexual-harrasment/dozens-turkish-womens-organisations-issue-statement-backing-latest-metoo-movement">UykularınızKaçsın</a> (“may you lose sleep”).</p> <p>In an inversion of the traditional narrative of the Global North leading the Global South in terms of feminist “progress”, Argentina’s “<a href="https://www.auswhn.com.au/blog/colour-green/">Green Wave</a>” has seen it decriminalise abortion, as has Colombia. Meanwhile, in 2022, the US Supreme Court <a href="https://theconversation.com/us-supreme-court-overturns-roe-v-wade-but-for-abortion-opponents-this-is-just-the-beginning-185768">overturned historic abortion legislation</a>.</p> <p>Whatever the nuances, the prevalence of such highly visible gender protests have led some feminists, like <a href="https://www.tandfonline.com/doi/abs/10.1080/14680777.2020.1804431">Red Chidgey</a>, lecturer in Gender and Media at King’s College London, to declare that feminism has transformed from “a dirty word and publicly abandoned politics” to an ideology sporting “a new cool status”.</p> <h2>Where to now?</h2> <p>How do we know when to pronounce the next “wave”? (Spoiler alert: I have no answer.) Should we even continue to use the term “waves”?</p> <p>The “wave” framework was first used to demonstrate feminist continuity and solidarity. However, whether interpreted as disconnected chunks of feminist activity or connected periods of feminist activity and inactivity, represented by the crests and troughs of waves, some believe it encourages binary thinking that produces <a href="https://www.tandfonline.com/doi/full/10.1080/14680777.2016.1190046">intergenerational antagonism</a>.</p> <p>Back in 1983, Australian writer and second-wave feminist Dale Spender, who died last year, <a href="https://www.historyworkshop.org.uk/feminism/radical-books-dale-spender-theres-always-been-a-womens-movement-this-century-1983/">confessed her fear</a> that if each generation of women did not know they had robust histories of struggle and achievement behind them, they would labour under the illusion they’d have to develop feminism anew. Surely, this would be an overwhelming prospect.</p> <p>What does this mean for “waves” in 2024 and beyond?</p> <p>To build vigorous varieties of feminism going forward, we might reframe the “waves”. We need to let emerging generations of feminists know they are not living in an isolated moment, with the onerous job of starting afresh. Rather, they have the momentum created by generations upon generations of women to build on.<!-- Below is The Conversation's page counter tag.

COVID is surging in Australia – and only 1 in 5 older adults are up to date with their boosters

<p><em><a href="https://theconversation.com/profiles/adrian-esterman-1022994">Adrian Esterman</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a></em></p> <p>Do you have family members or friends sick with a respiratory infection? If so, there’s a good chance it’s COVID, caused by the JN.1 variant currently circulating in Australia.</p> <p>In particular, New South Wales is reportedly experiencing its <a href="https://www.abc.net.au/news/2024-01-09/nsw-sydney-covid-variant-virus-pandemic-hospitalisations/103298610">highest levels</a> of COVID infections in a year, while Victoria is said to be facing a “<a href="https://www.9news.com.au/national/victoria-in-midst-of-double-wave-of-covid19--as-jn1-triggers-infections-surge/4dada2cb-7d56-436a-9490-cad1d908a29a">double wave</a>” after a surge late last year.</p> <p>But nearly four years into the pandemic, data collection is less comprehensive than it was, and of course, fewer people are testing. So what do we know about the extent of this wave? And importantly, are we adequately protected?</p> <h2>Difficulties with data</h2> <p>Tracking COVID numbers was easier in the first half of last year, when each state and territory provided a weekly update, giving us data on case notifications, hospitalisations, ICU numbers and deaths.</p> <p>In the second half of the year some states and territories switched to less frequent reporting while others stopped their regular updates. As a result, different jurisdictions now report at different intervals and provide varying statistics.</p> <p>For example, <a href="https://www.health.vic.gov.au/infectious-diseases/victorian-covid-19-surveillance-report">Victoria</a> still provides weekly reports, while NSW publishes <a href="https://www.health.nsw.gov.au/Infectious/covid-19/Documents/respiratory-surveillance-20240106.pdf">fortnightly updates</a>.</p> <p>While each offer different metrics, we can gather – particularly from data on hospitalisations – that both states are experiencing a wave. We’re also seeing high levels of COVID <a href="https://www.health.vic.gov.au/infectious-diseases/victorian-covid-19-surveillance-report">in wastewater</a>.</p> <p>Meanwhile, <a href="https://health.nt.gov.au/covid-19/data">Northern Territory Health</a> simply tell you to go to the Australian government’s Department of Health website for COVID data. This houses the only national COVID <a href="https://www.health.gov.au/topics/covid-19/reporting?language=und">data collection</a>. Unfortunately, it’s not up to date, difficult to use, and, depending on the statistic, often provides no state and territory breakdowns.</p> <p>Actual case notifications are provided on a separate <a href="https://nindss.health.gov.au/pbi-dashboard/">website</a>, although given the lack of testing, these are likely to be highly inaccurate.</p> <p>The <a href="https://www.health.gov.au/topics/covid-19/reporting?language=und">Department of Health website</a> does provide some other data that gives us clues as to what’s happening. For example, as of one month ago, there were 317 active outbreaks of COVID in aged care homes. This figure has been generally rising since September.</p> <p>Monthly prescriptions for antivirals on the Pharmaceutical Benefits Scheme were increasing rapidly in November, but we are not given more recent data on this.</p> <p>It’s also difficult to obtain information about currently circulating strains. Data expert Mike Honey provides a regularly updated <a href="https://github.com/Mike-Honey/covid-19-genomes?tab=readme-ov-file#readme">snapshot</a> for Australia based on data from GISAID (the Global Initiative on Sharing All Influenza Data) that shows JN.1 rising in prevalence and accounting for about 40% of samples two weeks ago. The proportion is presumably higher now.</p> <h2>What’s happening elsewhere?</h2> <p>Many other countries are currently going through a COVID wave, probably driven to a large extent by JN.1. These include <a href="https://www.rnz.co.nz/news/national/506301/covid-19-complacency-waning-immunity-contribute-to-fifth-wave-epidemiologist">New Zealand</a>, <a href="https://www.independent.co.uk/news/world/europe/facemasks-mandatory-spain-hospitals-b2475563.html">Spain, Greece</a> and the United States.</p> <p>According to cardiologist and scientist Eric Topol, the US is currently experiencing its <a href="https://www.latimes.com/opinion/story/2024-01-04/covid-2024-flu-virus-vaccine">second biggest wave</a> since the start of the pandemic, linked to JN.1.</p> <h2>Are vaccines still effective?</h2> <p>It’s expected the current COVID vaccines, which target the omicron variant XBB.1.5, are still <a href="https://www.gavi.org/vaccineswork/seven-things-you-need-know-about-jn1-covid-19-variant">effective</a> at reducing hospitalisations and deaths from JN.1 (also an omicron offshoot).</p> <p>The Australian Technical Advisory Group on Immunisation (ATAGI) updated their <a href="https://www.health.gov.au/news/atagi-update-on-the-covid-19-vaccination-program">advice</a> on booster shots in September last year. They recommended adults aged over 75 should receive an additional COVID vaccine dose in 2023 if six months had passed since their last dose.</p> <p>They also suggest all adults aged 65 to 74 (plus adults of any age who are severely immunocompromised) should consider getting an updated booster. They say younger people or older adults who are not severely immunocompromised and have already had a dose in 2023 don’t need further doses.</p> <p>This advice is very confusing. For example, although ATAGI does not recommend additional booster shots for younger age groups, does this mean they’re not allowed to have one?</p> <p>In any case, as of <a href="https://www.health.gov.au/resources/publications/covid-19-vaccine-rollout-update-8-december-2023?language=en">December 6</a>, only 19% of people aged 65 and over had received a booster shot in the last six months. For those aged 75 and over, this figure is 23%. Where is the messaging to these at-risk groups explaining why updating their boosters is so important?</p> <h2>Should we be concerned by this wave?</h2> <p>That depends on who we mean by “we”. For those who are vulnerable, absolutely. Mainly because so few have received an updated booster shot and very few people, including the elderly, are wearing masks.</p> <p>For the majority of people, a COVID infection is unlikely to be serious. The biggest concern for younger people is the risk of long COVID, which research suggests <a href="https://www.nature.com/articles/s41591-022-02051-3">increases</a> with each reinfection.</p> <h2>What should we expect in 2024?</h2> <p>It’s highly likely we will see repeated waves of infections over the next 12 months and beyond, mainly caused by waning immunity from previous infection, vaccination or both, and new subvariants.</p> <p>Unless a new subvariant causes more severe disease (and at this stage, there’s no evidence JN.1 does), we should be able to manage quite well, without our hospitals becoming overwhelmed. However, we should be doing more to protect our vulnerable population. Having only one in five older people up to date with a booster and more than 300 outbreaks in aged care homes is not acceptable.</p> <p>For those who are vulnerable, the usual advice applies. Make sure you’re up to date with your booster shots, wear a P2/N95 mask when out and about, and if you do get infected, take antivirals as soon as possible.<!-- Below is The Conversation's page counter tag.

5 ultimate tips before you schedule heating and cooling maintenance in Adelaide

<p><span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">In Adelaide's climate, a reliable heating and cooling system isn't just a luxury – it's a must-have! Beyond comfort, maintaining these lifesavers at peak efficiency helps you tackle the temperature swings. But how do you ensure they're up to snuff year-round?</span></p> <p><span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">Walk about our </span><a style="text-decoration: none;" href="https://www.metropolitanheatingandcooling.com.au/blog/how-often-should-i-schedule-heating-and-cooling-maintenance/"><span style="font-size: 11pt; font-family: Arial,sans-serif; color: #1155cc; background-color: transparent; font-weight: bold; font-style: normal; font-variant: normal; text-decoration: underline; -webkit-text-decoration-skip: none; text-decoration-skip-ink: none; vertical-align: baseline; white-space: pre-wrap;">Maintenance and Routine Services Guide</span></a><span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">. They'll arm you with everything from understanding your unique system, spotting trouble early on, the cleaning nitty-gritty, right to zeroing in on the best time for that crucial maintenance in Adelaide.</span></p> <p><span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">Now, let’s dive into these handy pointers and get you sorted, shall we?</span></p> <h2 dir="ltr" style="line-height: 1.38; margin-top: 18pt; margin-bottom: 4pt;"><span style="font-size: 17pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: bold; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">What You Need to Remember</span></h2> <p><img src="https://oversixtydev.blob.core.windows.net/media/2023/12/HeatingCooling02.jpg" alt="" width="1280" height="720" /></p> <p><span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">Aside from air conditioner repairs and ducted gas heating repairs, diligently scheduling heating and cooling maintenance in Adelaide is just as important. Whether it's your first time scheduling one or you've done this before, these five tips can surely help you.</span></p> <h3 dir="ltr" style="line-height: 1.38; margin-top: 14pt; margin-bottom: 4pt;"><span style="font-size: 13pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: bold; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">Tip #1: Understand Your Air Conditioning System</span></h3> <p><span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">The kind of air conditioning unit you have can make a big difference to your maintenance schedule. Could be split systems, ducted gas heating systems, or the lot. Most Adelaide homes use evaporative coolers, and servicing these units is quite a different ball game compared to reverse-cycle systems.</span></p> <h3 dir="ltr" style="line-height: 1.38; margin-top: 14pt; margin-bottom: 4pt;"><span style="font-size: 13pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: bold; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">Tip #2: Recognise Signs of Trouble</span></h3> <p><span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">Today's air conditioning units are excellent at giving you a heads-up about an upcoming hassle. If it's not putting out enough cool air, or it's not running as it should, it might be time to call someone for those heating and cooling repairs. Nipping these problems in the bud is what you should be aiming for.</span></p> <h3 dir="ltr" style="line-height: 1.38; margin-top: 14pt; margin-bottom: 4pt;"><span style="font-size: 13pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: bold; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">Tip #3: Regular Cleaning and Air Filter Changes</span></h3> <p><span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">Keeping your air conditioners' filters clean and changing them regularly is a clever way to keep your air conditioning service in tip-top shape. The air filters, in particular, play a big role in this. Blocked air filters can lead to poor airflow and overworking of the system, which bumps your running costs up the wall.</span></p> <p><span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">However, don't stop at just swapping out the generic filters. Give the other components like the coils and fins in your air conditioner system a good clean as well.</span></p> <h3 dir="ltr" style="line-height: 1.38; margin-top: 14pt; margin-bottom: 4pt;"><span style="font-size: 13pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: bold; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">Tip #4: Regular Cooling and Heating System Checks</span></h3> <p><span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">Keeping up with regular air conditioning repair services makes sure your system is always raring to go. Your system needs to be a ripper, ready to go the minute you need it. Maintenance involves cleaning and checking big brands like Mitsubishi Electric, making sure any faults are out of the picture.</span></p> <h3 dir="ltr" style="line-height: 1.38; margin-top: 14pt; margin-bottom: 4pt;"><span style="font-size: 13pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: bold; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">Tip #5: Knuckling Down the Right Time for Check-up</span></h3> <p><span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">The best time to schedule air conditioning services or ducted gas, heating, and cooling systems repairs is before peak use - early autumn for heating systems and early spring for your cooling systems. This way, you're sorted with a climate-controlled environment just when you need it.</span></p> <h2 dir="ltr" style="line-height: 1.38; margin-top: 18pt; margin-bottom: 4pt;"><span style="font-size: 17pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: bold; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">The Importance of Scheduling Heating and Cooling Maintenance</span></h2> <p><img src="https://oversixtydev.blob.core.windows.net/media/2023/12/HeatingCooling03.jpg" alt="" width="1280" height="720" /></p> <p><span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">We have our busy days, and there are times when scheduling maintenance for our heating and cooling unit is the last thing on our list. However, there are plenty of reasons why sticking to heating and cooling maintenance like glue is so important:</span></p> <h3 dir="ltr" style="line-height: 1.38; margin-top: 14pt; margin-bottom: 4pt;"><span style="font-size: 13pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: bold; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">It Keeps Your Systems Efficient</span></h3> <p><span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">Routine maintenance keeps your system running efficiently. A well-maintained unit uses less energy to run and is therefore less likely to punch a hole in your wallet when the energy bill shows up.</span></p> <h3 dir="ltr" style="line-height: 1.38; margin-top: 14pt; margin-bottom: 4pt;"><span style="font-size: 13pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: bold; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">It Helps Prevent Breakdowns</span></h3> <p><span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">Regular maintenance can spot potential problems and get them sorted before you're left stuck without climate control on a stinking hot day or a freezing cold night. It's a lot cheaper and less hassle to prevent problems than to fix them once they've happened.</span></p> <h3 dir="ltr" style="line-height: 1.38; margin-top: 14pt; margin-bottom: 4pt;"><span style="font-size: 13pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: bold; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">It Prolongs the Life of Your Unit</span></h3> <p><span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">Frequent maintenance can extend the lifespan of your heating and cooling system.

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

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

Here’s what to know about COVID antivirals as we navigate this <a href="https://www.smh.com.au/national/a-slightly-more-dangerous-place-australia-is-in-its-eighth-covid-wave-20231030-p5eg5k.html">eighth COVID wave</a>.</p> <h2>What antivirals are available?</h2> <p><a href="https://www.tga.gov.au/resources/artg/389801">Paxlovid</a> is a combination of two different drug molecules, nirmatrelvir and ritonavir. The nirmatrelvir works by blocking an enzyme called a protease that the virus needs to replicate. The ritonavir is included in the medicine to protect the nirmatrelvir, stopping the body from breaking it down.</p> <p>Molnupiravir, marketed as <a href="https://www.tga.gov.au/resources/artg/372650">Lagevrio</a>, works by forcing errors into the RNA of SARS-CoV-2 (the virus that causes COVID) as it replicates. As these errors build up, the virus becomes less effective.</p> <p>This year in Australia, the <a href="https://theconversation.com/were-in-a-new-covid-wave-what-can-we-expect-this-time-216820">XBB COVID strains</a> have dominated, and acquired a couple of key mutations. When COVID mutates into new variants, it doesn’t affect the ability of either Paxlovid or Lagevrio to work because the parts of the virus that change from the mutations aren’t those targeted by these two drugs.</p> <p>This is different to the <a href="https://app.magicapp.org/#/guideline/L4Q5An/section/E8kMVn">monoclonal antibody-based medicines</a> that were developed against specific strains of the virus. These drugs are not thought to be effective for any variant of the virus <a href="https://www.who.int/activities/tracking-SARS-CoV-2-variants">from omicron XBB.1.5 onwards</a>, which includes the current wave. This is because these drugs recognise certain proteins expressed on the surface of SARS-CoV-2, which have changed over time.</p> <h2>What does the evidence say?</h2> <p>As Lagevrio and Paxlovid are relatively new medicines, we’re still learning how well they work and which patients should use them.</p> <p>The latest <a href="https://app.magicapp.org/#/guideline/L4Q5An/section/L0OPkj">evidence</a> suggests Paxlovid decreases the risk of hospitalisation if taken early by those at <a href="https://www.nsw.gov.au/covid-19/testing-managing/antivirals">highest risk of severe disease</a>.</p> <p>Results from <a href="https://www.nejm.org/doi/10.1056/NEJMoa2116044">a previous trial</a> suggested Lagevrio might reduce COVID deaths. But a more recent, <a href="https://papers.ssrn.com/sol3/papers.cfm?abstract_id=4237902">larger trial</a> indicated Lagevrio doesn’t significantly reduce hospitalisations or deaths from the virus.</p> <p>However, few people at highest risk from COVID were included in this trial. So it could offer some benefit for patients in this group.</p> <p>In Australia, Lagevrio is not routinely <a href="https://app.magicapp.org/#/guideline/L4Q5An/section/L0OPkj">recommended</a> and Paxlovid is preferred. However, not all patients can take Paxlovid. For example, people with medical conditions such as <a href="https://www.paxlovidhcp.com/moderate-renal-impairment">severe kidney or liver impairment</a> shouldn’t take it because these issues can affect how well the body metabolises the medication, which increases the risk of side effects.</p> <p>Paxlovid also can’t be taken alongside some <a href="https://www.cec.health.nsw.gov.au/__data/assets/pdf_file/0020/702821/Information-for-patients-family-and-carers-nirmatrelvir-and-ritonavir.PDF">other medications</a> such as those for certain heart conditions, mental health conditions and cancers. For high-risk patients in these cases, Lagevrio can be considered.</p> <p>Some people who take COVID antivirals will experience side effects. Mostly these are not serious and will go away with time.</p> <p>Both <a href="https://www.cec.health.nsw.gov.au/__data/assets/pdf_file/0020/702821/Information-for-patients-family-and-carers-nirmatrelvir-and-ritonavir.PDF">Paxlovid</a> and <a href="https://www.cec.health.nsw.gov.au/__data/assets/pdf_file/0008/702818/Information-for-patients-family-and-carers-molnupiravir.PDF">Lagevrio</a> can cause diarrhoea, nausea and dizziness. Paxlovid can also cause side effects including muscle aches and weakness, changes in taste, loss of appetite and abdominal pain. If you experience any of these, you should contact your doctor.</p> <p>More serious side effects of both medicines are allergic reactions, such as shortness of breath, swelling of the face, lips or tongue and a severe rash, itching or hives. If you experience any of these, call 000 immediately or go straight to the nearest emergency department.</p> <h2>Be prepared</h2> <p>Most people will be able to manage COVID safely at home without needing antivirals. However, those at higher risk of severe COVID and therefore <a href="https://www.nsw.gov.au/covid-19/testing-managing/antivirals#:%7E:text=Both%20are%20available%20in%20NSW,Lagevrio%C2%AE%20(molnupiravir)launch.">eligible for antivirals</a> should seek them. This includes people aged 70 or older, people aged 50 or older or Aboriginal people aged 30 or older with one additional risk factor for severe illness, and people 18 or older who are immunocompromised.</p> <p>If you are in any of these groups, it’s important you <a href="https://www.health.nsw.gov.au/Infectious/covid-19/Documents/translated/plan-ahead-covid-flu-english.pdf">plan ahead</a>. Speak to your health-care team now so you know what to do if you get COVID symptoms.</p> <p>If needed, this will ensure you can start treatment as soon as possible. It’s important antivirals are started within <a href="https://www.nsw.gov.au/covid-19/testing-managing/antivirals#:%7E:text=Both%20are%20available%20in%20NSW,Lagevrio%C2%AE%20(molnupiravir)launch.">five days of symptom onset</a>.</p> <p>If you’re a high-risk patient and you test positive, contact your doctor straight away.

We’re in a new COVID wave. What can we expect this time?

<p><a href="https://theconversation.com/profiles/james-wood-107417">James Wood</a>, <em><a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a></em>; <a href="https://theconversation.com/profiles/bette-liu-1484488">Bette Liu</a>, <em><a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a></em>; <a href="https://theconversation.com/profiles/katie-louise-flanagan-1066858">Katie Louise Flanagan</a>, <em><a href="https://theconversation.com/institutions/university-of-tasmania-888">University of Tasmania</a></em>, and <a href="https://theconversation.com/profiles/stuart-turville-1273716">Stuart Turville</a>, <em><a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a></em></p> <p>Australia is now into its <a href="https://www.abc.net.au/news/2023-11-02/nsw-sydney-covid-christmas-fresh-wave/103051190">next COVID wave</a>. We’ve seen hints of this for a while. Case numbers and indicators of severe disease began rising in Victoria in August. But it has taken several months for a consistent pattern to emerge across Australia.</p> <p>Now we see evidence of this new wave via <a href="https://www.health.vic.gov.au/sites/default/files/2023-11/victorian-covid-19-surveillance-report-03-november-2023.pdf">wastewater surveillance</a> for traces of SARS-CoV-2, the virus that causes COVID. We also see <a href="https://www.health.gov.au/topics/covid-19/weekly-reporting">rises</a> in COVID-related hospital admissions and antiviral prescriptions. Compared to past waves, this one has built up slowly and over a longer period.</p> <p>Here’s what we know about this new wave and what to expect over the coming weeks.</p> <h2>How do we know we’re in a new COVID wave?</h2> <p>In earlier waves, when more people were testing for COVID and reporting their results, we were more confident case numbers were a reasonable reflection of how COVID was tracking.</p> <p>However, now, a more useful indicator for COVID nationally is to look at trends in the number of prescriptions for the antiviral medications ritonavir (Paxlovid) and molnupiravir (Lagevrio) on the Pharmaceutical Benefits Scheme (PBS).</p> <p>In the graph below, which is drawn from <a href="https://www.health.gov.au/topics/covid-19/weekly-reporting">national prescribing data</a>, you can clearly see script numbers rising.</p> <p><iframe id="3d26e" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/3d26e/1/" width="100%" height="400px" frameborder="0"></iframe></p> <h2>When will we hit the peak?</h2> <p>It has become more difficult to predict the size and timing of the peak. Reduced access to COVID testing and fewer requirements or opportunities to report test results, combined with the slow growth rate for this wave, give a wider range of possibilities.</p> <p>The wave is also likely to differ between states and territories, as some got off to a later start.</p> <p>However, given the wave’s slow growth rate and further increases in hybrid immunity (immunity from both vaccination and infection) over 2023, it’s reasonable to expect this to be the smallest Omicron wave so far.</p> <p>We also expect it will be over by early in the summer holiday period. That’s when rates of community contact decline significantly, as work and school contacts are much reduced. That means fewer opportunities for the virus to spread between networks of family and friends.</p> <h2>Why now?</h2> <p>It’s unlikely this latest COVID wave stems from changes in behaviour. People are generally out and about, fewer people are wearing masks in public. But we don’t see any dramatic shifts in this type of behaviour in 2023 compared with 2022.</p> <p>It’s not a seasonal cause, given respiratory viruses tend to spread better in winter, when we’re cooped up indoors with others.</p> <p>It’s unlikely it’s our <a href="https://www.medrxiv.org/content/10.1101/2023.08.26.23294679v1">waning immunity</a> from infection or vaccination that’s prompting these successive waves.</p> <p>Instead, we’re seeing the result of a constantly mutating virus. Successful SARS-CoV-2 variants are gradually acquiring mutations. Some of these changes reduce the ability of existing antibodies to bind to and neutralise the virus. So it appears it’s still the “immune escape” variants that are behind these latest waves.</p> <h2>Which variants are to blame?</h2> <p>The primary viral lineage in Australia this year has been XBB. Over the past six months, its two most influential mutations have been:</p> <ul> <li> <p>the F456L mutation that led to the rise of EG.5.1, also known as Eris</p> </li> <li> <p>more recently, the paired “FLip” mutations F456L+L455F. We see these in offspring of Eris and in much-less closely related lineages. This is a clear sign these mutations help the virus spread better.</p> </li> </ul> <p>Both the single and paired mutations make existing antibodies less effective at blocking SARS-CoV-2 from binding to critical receptors on our cells. This increases our susceptibility to infection.</p> <p> </p> <p>The novel BA.2.86 lineage – colloquially known as Pirola – was first reported in Denmark in August and has many unique mutations. It has not been influential so far in this wave in Australia. But it has continued to evolve. And we may see it play a much bigger role in Australia in 2024.</p> <h2>Who is most at risk during this COVID wave?</h2> <p>Since the start of the pandemic, rates of COVID-related death and severe disease have greatly declined. That’s due to <a href="https://www.thelancet.com/journals/laninf/article/PIIS1473-3099(22)00801-5/fulltext">widespread</a> vaccination and hybrid immunity, and a major change in the Omicron variant that’s made the virus less-likely to <a href="https://pubmed.ncbi.nlm.nih.gov/35104837/">infect the lung</a>.</p> <p>However, provisional statistics show there have been about <a href="https://www.abs.gov.au/statistics/health/causes-death/provisional-mortality-statistics/latest-release">3,000</a> registered COVID deaths in Australia from January to July 2023.</p> <p>Older people and those with weaker immune systems are expected to remain at <a href="https://www.sciencedirect.com/science/article/pii/S2468266723000798">greatest risk</a> of developing severe COVID during this current wave.</p> <p>This is the rationale for the Australian Technical Advisory Group on Immunisation’s (ATAGI) September <a href="https://www.health.gov.au/news/atagi-update-on-the-covid-19-vaccination-program">recommendation</a> for people aged 75 or older to get boosted if more than six months had passed since their last vaccine dose.</p> <p>ATAGI also recommended people aged 65-74, and people 18 years and over with severe immunocompromising conditions, consider having another booster.</p> <p>But, by the end of October 2023, <a href="https://www.health.gov.au/sites/default/files/2023-10/covid-19-vaccine-rollout-update-27-october-2023.pdf">it was estimated</a> only one-quarter of Australians aged 65-74, one-third of people aged 75 or over and fewer than half (45%) of people in aged care had received a COVID vaccine in the past six months.</p> <figure class="align-center "><img src="https://images.theconversation.com/files/558309/original/file-20231108-19-5fu6vv.jpg?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/558309/original/file-20231108-19-5fu6vv.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=249&fit=crop&dpr=1 600w, https://images.theconversation.com/files/558309/original/file-20231108-19-5fu6vv.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=249&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/558309/original/file-20231108-19-5fu6vv.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=249&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/558309/original/file-20231108-19-5fu6vv.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=313&fit=crop&dpr=1 754w, https://images.theconversation.com/files/558309/original/file-20231108-19-5fu6vv.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=313&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/558309/original/file-20231108-19-5fu6vv.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=313&fit=crop&dpr=3 2262w" alt="Woman receives vaccination" /><figcaption><span class="caption">People with immunocompromising conditions should get boosted.</span> <span class="attribution"><a class="source" href="https://www.shutterstock.com/image-photo/woman-wearing-protective-face-mask-getting-1966499908">Shutterstock</a></span></figcaption></figure> <h2>Which vaccines are available?</h2> <p>Currently available bivalent vaccines protect against the original ancestral strain of SARS-CoV-2 (now extinct) plus the newer BA.1 or BA.4/5 variants. These bivalent vaccines also protect us against <a href="https://assets.publishing.service.gov.uk/media/6527f0bfaea2d0000d219c69/vaccine-surveillance-report-2023-week-41.pdf">severe disease</a> from the Omicron variants circulating now, such as XBB.</p> <p>But we can expect newer monovalent XBB.1.5 vaccines soon, now the Therapeutic Goods Administration has <a href="https://www.tga.gov.au/products/covid-19/covid-19-vaccines/covid-19-vaccines-regulatory-status">approved them</a>. These are expected to provide <a href="https://www.medrxiv.org/content/10.1101/2023.10.04.23296545v1.full.pdf">better protection</a> against newer Omicron variants than the currently available <a href="https://www.sciencedirect.com/science/article/pii/S2213260023003065">bivalent vaccines</a>.</p> <p>In the meantime, boosting with any available COVID vaccine will provide <a href="https://assets.publishing.service.gov.uk/media/6527f0bfaea2d0000d219c69/vaccine-surveillance-report-2023-week-41.pdf">good protection</a> for vulnerable people.</p> <h2>What might we expect from COVID in 2024?</h2> <p>The Northern Hemisphere appears to have settled into an approximate seasonal pattern of COVID infections in 2023 and it’s plausible Australia will follow suit.</p> <p>If so, we should plan for overlapping seasonal epidemics of our three most important respiratory viruses: SARS-CoV-2, influenza and respiratory syncytial virus (RSV). So hospitals may need to plan ahead for larger peaks in admissions.</p> <p>Hopefully, new <a href="https://www.cdc.gov/vaccines/hcp/acip-recs/vacc-specific/rsv.html">vaccines for RSV</a>, and more broadly protective <a href="https://www.nih.gov/news-events/nih-research-matters/research-context-progress-toward-universal-vaccines">flu and COVID vaccines</a> to be developed over the next decade, should help.<!-- Below is The Conversation's page counter tag.

Heated argument between economy passengers reignites plane etiquette debate

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

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

<p><em><a href="https://theconversation.com/profiles/amy-peden-1136424">Amy Peden</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a></em></p> <p>Hospital admissions for injuries directly attributable to extreme weather events – such as heatwaves, bushfires and storms – have increased in Australia over the past decade.</p> <p>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.</p> <p>In 2021-22, there were 754 injury hospitalisations directly related to extreme weather, compared to 576 in 2011-12.</p> <p>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>.</p> <p>As Australia heads into summer with an El Niño, it’s important understand and prepare for the health risks associated with extreme weather.</p> <h2>A spike every three years</h2> <p>Extreme weather-related hospitalisations have spiked at more than 1,000 cases every three years, with the spikes becoming progressively higher. There were:</p> <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> <p><iframe id="vLaas" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/vLaas/1/" width="100%" height="400px" frameborder="0"></iframe></p> <p>In each of these three years, extreme heat had the biggest impact on hospital admissions and deaths.</p> <p><iframe id="P03sm" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/P03sm/1/" width="100%" height="400px" frameborder="0"></iframe></p> <p>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.</p> <p>In 2011-12, there were 354 injury hospitalisations directly related to extreme heat. This rose to 579 by 2021-22.</p> <h2>El Niño and La Niña</h2> <p>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>.</p> <p>In Australia, El Niño drives a period of reduced rainfall, warmer temperatures and increased bushfire danger.</p> <p>La Niña, on the other hand, is associated with above average rainfall, cooler daytime temperatures and increased chance of tropical cyclones and flood events.</p> <p>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.</p> <p>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.</p> <p>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.</p> <h2>Regional differences</h2> <p>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:</p> <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&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/556987/original/file-20231101-27-3c98xm.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=632&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/556987/original/file-20231101-27-3c98xm.png?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=632&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/556987/original/file-20231101-27-3c98xm.png?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=632&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/556987/original/file-20231101-27-3c98xm.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=794&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/556987/original/file-20231101-27-3c98xm.png?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=794&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/556987/original/file-20231101-27-3c98xm.png?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=794&amp;fit=crop&amp;dpr=3 2262w" alt="" /><figcaption><span class="attribution"><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></span></figcaption></figure> <p>The report also includes state and territory data on hospitalisations related to extreme cold and storms.</p> <p>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.</p> <p>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.</p> <h2>What about for bushfires?</h2> <p>Over the ten-year period studied, there were 894 hospitalisations and 65 deaths related to bushfires.</p> <p>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.</p> <p>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.</p> <p>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).</p> <h2>Some people are particularly vulnerable</h2> <p>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>.</p> <p>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.</p> <p>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.</p> <p>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.</p> <h2>We still don’t have a full picture</h2> <p>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.</p> <p>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”.</p> <p>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.</p> <p>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.</p> <p><em>This article was co-authored by Sarah Ahmed and Heather Swanston from the Injuries and System Surveillance Unit at the Australian Institute of Health and Welfare.</em><!-- Below is The Conversation's page counter tag.

4 ways to support someone with dementia during extreme heat

<p><em><a href="https://theconversation.com/profiles/nikki-anne-wilson-342631">Nikki-Anne Wilson</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a></em></p> <p>Our ability to adapt our behaviour to changes in temperature takes a significant amount of thought and decision making. For example, we need to identify suitable clothing, increase our fluid intake, and understand how to best keep the house cool.</p> <p>A person with dementia may find some or all these things challenging. These and other factors mean, for someone with dementia, extreme heat <a href="https://pubmed.ncbi.nlm.nih.gov/31520832/#:%7E:text=Conclusion%3A%20Heatwaves%20increased%20the%20risk,heat%2Drelated%20Alzheimer's%20disease%20burden.">can be deadly</a>.</p> <p>But as the temperature rises, friends, relatives and carers can help.</p> <h2>El Niño means there are challenges ahead</h2> <p>The recent declaration of <a href="https://www.abc.net.au/news/2023-09-19/bureau-of-meteorology-el-nino-blog/102875154">another El Niño</a> means we need to think about how we can best support those more vulnerable to be safe during the warmer months.</p> <p>Extreme heat and bushfires bring unique challenges for someone with dementia.</p> <p>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.</p> <p>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.</p> <p>Emergency evacuations can also be confusing and distressing for a person with dementia, so it is important to think ahead.</p> <h2>Why are people with dementia more at risk?</h2> <p>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.</p> <p>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.</p> <p>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.</p> <p>A person with dementia can also wander and become lost, which can be dangerous in extreme heat.</p> <h2>4 ways to support someone with dementia</h2> <p><strong>1. Avoid dehydration and heatstroke</strong></p> <p>Try to avoid dehydration by encouraging someone to drink throughout the day. It’s better to have <a href="https://pubmed.ncbi.nlm.nih.gov/31769256/">small amounts</a> of liquid regularly instead of a large amount all at once. Little and often will help maximise hydration while avoiding sudden trips to <a href="https://www.betterhealth.vic.gov.au/health/conditionsandtreatments/dementia-continence-issues#causes-of-incontinence-in-people-with-dementia">the bathroom</a>.</p> <p>Try to offer different types of drinks, or ice blocks. Placing drinks in sight can help as a reminder to drink. Choose foods with a high liquid content, such as fruit, salads, cool broths and yoghurt.</p> <p>Look out for <a href="https://www.nia.nih.gov/health/hot-weather-safety-older-adults#:%7E:text=Signs%20of%20heat%20stroke%20are,as%20under%20shade%20or%20indoors.">signs of heatstroke</a>, such as increased confusion beyond what the person would usually experience. Heatstroke may be more difficult to spot in someone living with dementia so it is important to check in when possible and to help them cool down if needed.</p> <p><strong>2. Cool the home</strong></p> <p>Try to modify their home to make it easier to stay cool. Some air-conditioners have complex settings so make sure the temperature is set appropriately and the person with dementia knows how to use the controls.</p> <p>It is important to keep blinds and curtains shut where possible to reduce heat. However, ensure the <a href="https://www.scie.org.uk/dementia/supporting-people-with-dementia/dementia-friendly-environments/lighting.asp">lighting is adequate</a> to avoid falls.</p> <p>Try to support the person to make suitable clothing choices for the season by having cool, lightweight options easily available.</p> <p><strong>3. Think about communications early</strong></p> <p>If someone with dementia lives alone, consider how you will maintain contact in an emergency.</p> <p>Some people may not realise many landlines don’t work in a power outage, and of course, mobile phones can’t be recharged. Ensure the person with dementia has access to an <a href="https://www.telstra.com.au/support/category/home-phone/uninterruptible-power-supply">uninterruptable power supply</a>. This can help maintain communication for a few hours in a blackout.</p> <p><strong>4. Have an evacuation plan</strong></p> <p>In case of fire, flash flooding or severe storm, <a href="https://dementiaresearch.org.au/wp-content/uploads/2017/10/2447_DCRC_Prep_natural_disaster_EBook_5.pdf">have an evacuation plan</a>. If the person with dementia attends a day or respite centre, know their plan too.</p> <p>The situation can change quickly in an emergency, and this can be particularly overwhelming for people with cognitive issues.</p> <p>Understand that someone with dementia may become distressed when their routine is disrupted. So be prepared with some simple activities or comfort items, current medications, and any specific medical information.</p> <p>Stay up-to-date with <a href="http://www.bom.gov.au/">current warnings</a> and act early whenever possible.</p> <h2>We can all help</h2> <p>It’s not just carers of people with dementia who can help. We can all ensure people with dementia stay safe and cool this spring and summer.</p> <p>So remember to check in on your relatives, friends and neighbours or arrange for someone to do so on your behalf.<!-- Below is The Conversation's page counter tag.

Lisa Curry's emotional post sparks a wave of support and love

<p>Lisa Curry has shared a heartfelt tribute on the third anniversary of her daughter Jaimi's death. </p> <p>Jaimi passed away in 2020 after a long health battle, at just 33 years old, and is the daughter of Lisa and former Ironman Grant Kenny. </p> <p>Lisa took to Instagram to commemorate her daughter with a painting of Jaimi that she commissioned to a local artist, and share her grief journey. </p> <p>"3 years ago, our beautiful daughter Jaimi took her last breath. We all love you and miss you everyday Jaimi and hope you’re at peace. It still feels like yesterday," she began the long and emotional post. </p> <p>“We all love you and miss you every day Jaimi and hope you’re at peace.</p> <p>“It’s been a s*** and sad week, where I’ve needed lots of hugs and am constantly wiping my tears away. I tell myself to breathe because I know it’s a bad day, not a bad life.</p> <p>“I’m doing ok ... but feeling sad on the inside while trying to be happy on the outside is overwhelming and feels exhausting," she added. </p> <p>Lisa also said that sometimes she can barely recognise herself in the mirror because she looks like "a mess" and other times she sees "the old Lisa." </p> <p>"The path to recovery is long and can only be done in my own time.</p> <p>"The last 3 years has been a long, slow, painful, uneventful decline in my health and my soul. I talk out loud, frustratingly scolding myself to get my s*** together. There are days when I don’t care about anything.</p> <p>"I need to change that talk to be more positive and give myself permission that it’s ok to move forward.</p> <p>"Moving on doesn’t mean letting go. I will never let her go," she added. </p> <blockquote class="instagram-media" style="background: #FFF; border: 0; border-radius: 3px; box-shadow: 0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15); margin: 1px; max-width: 540px; min-width: 326px; padding: 0; width: calc(100% - 2px);" data-instgrm-captioned="" data-instgrm-permalink="https://www.instagram.com/p/CxJb9jkhg5C/?utm_source=ig_embed&amp;utm_campaign=loading" data-instgrm-version="14"> <div style="padding: 16px;"> <div style="display: flex; flex-direction: row; align-items: center;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 40px; margin-right: 14px; width: 40px;"> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 100px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 60px;"> </div> </div> </div> <div style="padding: 19% 0;"> </div> <div style="display: block; height: 50px; margin: 0 auto 12px; width: 50px;"> </div> <div style="padding-top: 8px;"> <div style="color: #3897f0; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: 550; line-height: 18px;">View this post on Instagram</div> </div> <div style="padding: 12.5% 0;"> </div> <div style="display: flex; flex-direction: row; margin-bottom: 14px; align-items: center;"> <div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(0px) translateY(7px);"> </div> <div style="background-color: #f4f4f4; height: 12.5px; transform: rotate(-45deg) translateX(3px) translateY(1px); width: 12.5px; flex-grow: 0; margin-right: 14px; margin-left: 2px;"> </div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(9px) translateY(-18px);"> </div> </div> <div style="margin-left: 8px;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 20px; width: 20px;"> </div> <div style="width: 0; height: 0; border-top: 2px solid transparent; border-left: 6px solid #f4f4f4; border-bottom: 2px solid transparent; transform: translateX(16px) translateY(-4px) rotate(30deg);"> </div> </div> <div style="margin-left: auto;"> <div style="width: 0px; border-top: 8px solid #F4F4F4; border-right: 8px solid transparent; transform: translateY(16px);"> </div> <div style="background-color: #f4f4f4; flex-grow: 0; height: 12px; width: 16px; transform: translateY(-4px);"> </div> <div style="width: 0; height: 0; border-top: 8px solid #F4F4F4; border-left: 8px solid transparent; transform: translateY(-4px) translateX(8px);"> </div> </div> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center; margin-bottom: 24px;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 224px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 144px;"> </div> </div> <p style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; line-height: 17px; margin-bottom: 0; margin-top: 8px; overflow: hidden; padding: 8px 0 7px; text-align: center; text-overflow: ellipsis; white-space: nowrap;"><a style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: normal; line-height: 17px; text-decoration: none;" href="https://www.instagram.com/p/CxJb9jkhg5C/?utm_source=ig_embed&amp;utm_campaign=loading" target="_blank" rel="noopener">A post shared by Lisa Curry AO (@lisacurry)</a></p> </div> </blockquote> <p>Lisa then said that she needed to start looking after herself so she can be "the mother, grannie, wife and friend that I should be." </p> <p>She then thanked local artist Donna Munro for the beautiful painting of her daughter, before asking her fans if they were okay, after noting that it was  R U OK Day. </p> <p>She reminded fans to talk to someone and sent “Love and strength to everyone who’s struggling for whatever reason.”</p> <p>Her followers flocked to the comments to offer their love and support, and thanked her for being open and vulnerable. </p> <p>“Do what you can today Lisa and let tomorrow take care of the rest.
