Woman rescued after getting stuck in between two boulders

A NSW woman found herself stuck in between two boulders after trying to retrieve her phone from a rocky abyss in the Hunter Valley. Emergency services were called to the wine region after reports the woman slipped and got stuck between two boulders down a three-metre crevice. Her friends initially tried to rescue her for an hour before calling Triple Zero for help. Photos shared by NSW Ambulance on Facebook showed the woman's feet poking out as she was wedged inside the crevice. Paramedics had to remove the heavy rocks, including winching out a massive 500kg boulder to create a safe exit. The entire process took around seven hours as the woman had been stuck in a tight "S" bend which made it challenging for the rescue team. "In my 10 years as a rescue paramedic I had never encountered a job quite like this, it was challenging but incredibly rewarding," NSW Ambulance Specialist Rescue Paramedic Peter Watts said. "Every agency had a role, and we all worked incredibly well together to achieve a good outcome for the patient." NSW Ambulance confirmed that the woman was unable to get her phone back.

How to choose a legal decision-maker as you get older – 3 things to consider

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/joseph-ibrahim-252671">Joseph Ibrahim</a>, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> and <a href="https://theconversation.com/profiles/amelia-grossi-1280226">Amelia Grossi</a>, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> “It’s my life and I’ll do what I want,” <a href="https://www.youtube.com/watch?v=HNzmrEgz_GI">sang</a> Eric Burdon of The Animals to the baby boomer generation. Unfortunately, that’s not always the case. As we get older, sometimes we are no longer capable of making our own decisions. Diseases that affect the brain such as dementia, stroke and head injury can impair cognition and thinking. Some people may choose to appoint a <a href="https://www.legislation.vic.gov.au/in-force/acts/medical-treatment-planning-and-decisions-act-2016/008">medical treatment decision-maker</a> or an <a href="https://www.legislation.vic.gov.au/in-force/acts/powers-attorney-act-2014/007">enduring power of attorney</a> to make certain decisions on their behalf. Alternatively, a legal tribunal or court may appoint <a href="https://www.legislation.vic.gov.au/in-force/acts/guardianship-and-administration-act-2019/005">a guardian or trustee</a> to help guide decisions about health care, finances, accommodation and lifestyle. Who is the right person to take on this important role? Is it the family member or partner who knows you best? Or someone with time and energy? Perhaps someone who understands the services you need – like a nurse, accountant or real estate agent? The role of a decision-making representative has <a href="https://www.alrc.gov.au/publication/equality-capacity-and-disability-in-commonwealth-laws-alrc-report-124/3-national-decision-making-principles-2/will-preferences-and-rights-2/#:%7E:text=The%20'best%20interests'%20principle%20is,an%20equal%20basis%20with%20others">changed significantly</a> in recent years, shifting from a paternalistic approach to a more person-centred focus. Our <a href="https://pubmed.ncbi.nlm.nih.gov/35157838/">research</a> looks at the differences between these approaches and how subconscious bias can influence decision-making. <h2>Taking care</h2> These days, guardianship has <a href="https://www.legislation.vic.gov.au/in-force/acts/guardianship-and-administration-act-2019/005">moved</a> from deciding what’s deemed to be in the individual’s “best interests” to what best reflects their “will and preferences”. While <a href="https://www.legislation.vic.gov.au/repealed-revoked/acts/guardianship-and-administration-act-1986/089">previously</a>, decisions were made for the person by their guardian or representative, new laws require representatives to enact the person’s “will and preferences”. That is, to make decisions with them. This is an important difference. The newer model gives the represented person more autonomy over personal, financial and other decisions. It recognises that even though a person may struggle with aspects of decision-making, they should not be excluded from decisions about how they live their life. This fundamental shift was <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6313688/">earlier adopted</a> by the United Nations in the <a href="https://www.ohchr.org/en/hrbodies/crpd/pages/conventionrightspersonswithdisabilities.aspx">Convention on the Rights of Persons with Disability</a>, to which Australia is a signatory. <h2>Challenging in real world situations</h2> The will and preferences <a href="https://supporteddecisionmaking.com.au/wp-content/uploads/sites/4/2021/08/Realising-will-preferences-and-rights-reconciling-differences-on-best-practice-support-for-decision-making.pdf">framework</a> may sound simple, but it can be <a href="https://www.tandfonline.com/doi/full/10.1080/09687599.2021.1941781">challenging in practice</a>, when concepts of empowerment are tricky to define and the will of someone with cognitive difficulties is hard to discern. Representatives <a href="https://supporteddecisionmaking.com.au/wp-content/uploads/sites/4/2021/08/Realising-will-preferences-and-rights-reconciling-differences-on-best-practice-support-for-decision-making.pdf">bring their own biases, perceptions and lived experience</a> to the role of supporting another person to make decisions. This subjectivity is a natural and an inherent part of decision-making. The representative faces the challenge of setting aside their own opinion and, instead, stepping into the shoes of the represented person to give effect to what they want. A mismatch between the age, gender, ethnicity, religion or socioeconomic status of the representative and the represented person can exacerbate this challenge. An older able-bodied female, who is deeply religious and from a middle-to-high income background might find it difficult to represent a young man with a disability who is an atheist and from a working-class background. Now, imagine a scenario where the young man expresses a desire to go bungee-jumping or parachuting, despite previously showing a fear of heights. What’s his representative to do? Older people and women generally <a href="https://www.tandfonline.com/doi/abs/10.1080/1366987032000105315?journalCode=rjrr20">have a lower appetite for risk</a>, as do those who have a faith and with a high socioeconomic status. A heightened perception of danger or a feeling the activity as frivolous, may lead to the representative reframing the situation with their subconscious bias. They may fail to respect the younger person’s will and preferences. Understanding what might shape a representative’s approach to decision-making is essential. Especially when decisions involve <a href="https://theconversation.com/do-you-want-to-be-resuscitated-this-is-what-you-should-think-about-before-deciding-105506">health</a> or <a href="https://theconversation.com/theres-no-need-to-lock-older-people-into-nursing-homes-for-their-own-safety-73954">living arrangements</a>. <h2>3 things to look for when selecting a legal decision-making representative</h2> 1. Deep understanding An intimate understanding of your situation is crucial. An ideal representative is someone who actively listens and has a holistic view of your circumstances. This may come from discussions with you and your loved ones. The representative must be careful your views are not outweighed by those of family or friends who are often more vocal. They should have a deep sense of who you are as an individual. 2. Self-awareness The person you choose should be able to describe their personal views and values and understand how their perspective may influence their decisions. This is vital to mitigate the effects of pre-existing bias. They should be able to reflect on their own lived experiences, to understand how their history shapes their approach to decision-making. They should be able to assess whether what you would do is the same as what they think you should do, and why. 3. Effective documentation A record of conversations between the representative and represented person often helps to illuminate a person’s will and preferences. Writing or recording compels us to commit to an idea and explain what we mean. It helps to clarify what is intended far better than a one-time conversation that may be remembered differently by participants. Further research is needed to better match representatives with represented persons. Improved tools are needed to identify the role of bias in decision-making and evaluate whether the represented person’s wills and preferences are being respected.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/177631/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/joseph-ibrahim-252671">Joseph Ibrahim</a>, Professor, Health Law and Ageing Research Unit, Department of Forensic Medicine, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> and <a href="https://theconversation.com/profiles/amelia-grossi-1280226">Amelia Grossi</a>, , <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

NRL legend calls for help to get newborn baby home

NRL legend Jesse Ramien and his partner Shell are pleading for help to get their newborn baby home after Shell's traumatic birth experience in Bali. The Cronulla Sharks player and his wife travelled to Bali for a friend's wedding while Shell was 33 weeks pregnant, who was cleared by her doctor before their trip. However, after just three days into their holiday, Shell went into early labour which quickly led to an emergency C-section, with mum under anaesthetic and baby boy Teo needing five minutes of resuscitation. Baby Teo was rushed into a neonatal intensive care unit, with his parents not able to meet him until the day after he was born. The family has been torn apart since with the parents still yet to hold Teo, who remains in an incubator, and older son Tallen returning home after Shell’s mother rushed to Bali to help. It is not known when the family can return to Australia, as Teo's condition is still unstable. “There’s just so much uncertainty here. We’ve been told by doctors it could be four weeks before our baby is okay to travel, but that could quickly change to five, six, or seven weeks, who knows,” Ramien told <a href="https://www.dailytelegraph.com.au/sport/nrl/sharks-star-jesse-ramiens-impassioned-plea-for-help-from-the-australian-government-to-source-flight-to-bring-baby-back-to-australia/news-story/1208830641c06ecb8c2450b95eeabece" target="_blank" rel="noopener" data-link-type="article-inline">News Corp</a>. “We’re doing everything to contact the Australian embassy to see how we can get home both as quickly as possible, so that our boy can get the medical attention he needs.” A family friend has set up a <a href="https://www.gofundme.com/f/need-your-help-to-fly-our-boy-teo-home" target="_blank" rel="noopener">GoFundMe</a> page to help the couple get home with their baby on an emergency flight, with $45,000 of their $100,000 goal already raised. “I’ll play for nothing just to get our baby boy home safely,” Ramien said. Shell, who received clearance from her obstetrician and the airline before travelling, ensured her pregnancy was covered by a top travel insurance package, however baby Teo’s medical costs — tallying more than $20,000 so far — are not included, while the total costs to get Baby Teo home could exceed $130,000. Ramien has been sharing updates on Instagram, posting a picture of his new son with the caption, “Home soon my boy,” while Shell added, “Won’t be long my boy, we'll be home soon.” Image credits: Instagram / GoFundMe

Getting antivirals for COVID too often depends on where you live and how wealthy you are

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/peter-breadon-1348098">Peter Breadon</a>, <a href="https://theconversation.com/institutions/grattan-institute-1168">Grattan Institute</a> Medical experts <a href="https://www.health.gov.au/health-alerts/covid-19/treatments/eligibility">recommend</a> antivirals for people aged 70 and older who get COVID, and for other groups at risk of severe illness and hospitalisation from COVID. But many older Australians have missed out on antivirals after getting sick with COVID. It is yet another way the health system is failing the most vulnerable. <h2>Who missed out?</h2> We <a href="https://grattan.edu.au/wp-content/uploads/2024/10/How-we-analysed-COVID-antiviral-uptake-Grattan-Institute.pdf">analysed</a> COVID antiviral uptake between March 2022 and September 2023. We found some groups were more likely to miss out on antivirals including Indigenous people, people from disadvantaged areas, and people from culturally and linguistically diverse backgrounds. Some of the differences will be due to different rates of infection. But across this 18-month period, many older Australians were infected at least once, and rates of infection were higher in some disadvantaged communities. <h2>How stark are the differences?</h2> Compared to the national average, Indigenous Australians were nearly 25% less likely to get antivirals, older people living in disadvantaged areas were 20% less likely to get them, and people with a culturally or linguistically diverse background were 13% less likely to get a script. People in remote areas were 37% less likely to get antivirals than people living in major cities. People in outer regional areas were 25% less likely. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/620627/original/file-20240920-20-yc7sq5.png?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/620627/original/file-20240920-20-yc7sq5.png?ixlib=rb-4.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/620627/original/file-20240920-20-yc7sq5.png?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=329&fit=crop&dpr=1 600w, https://images.theconversation.com/files/620627/original/file-20240920-20-yc7sq5.png?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=329&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/620627/original/file-20240920-20-yc7sq5.png?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=329&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/620627/original/file-20240920-20-yc7sq5.png?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=413&fit=crop&dpr=1 754w, https://images.theconversation.com/files/620627/original/file-20240920-20-yc7sq5.png?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=413&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/620627/original/file-20240920-20-yc7sq5.png?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=413&fit=crop&dpr=3 2262w" alt="" /></a><figcaption>Dispensing rates by group. Grattan Institute</figcaption></figure> Even within the same city, the differences are stark. In Sydney, people older than 70 in the affluent eastern suburbs (including Vaucluse, Point Piper and Bondi) were nearly twice as likely to have had an antiviral as those in Fairfield, in Sydney’s south-west. Older people in leafy inner-eastern Melbourne (including Canterbury, Hawthorn and Kew) were 1.8 times more likely to have had an antiviral as those in Brimbank (which includes Sunshine) in the city’s west. <h2>Why are people missing out?</h2> COVID antivirals should be taken when symptoms first appear. While awareness of COVID antivirals is generally strong, people often <a href="https://link.springer.com/article/10.1007/s40121-024-01003-3">don’t realise</a> they would benefit from the medication. They <a href="https://www.phrp.com.au/?p=43363">wait</a> until symptoms get worse and it is too late. Frequent GP visits make a big difference. Our analysis found people 70 and older who see a GP more frequently were much more likely to be dispensed a COVID antiviral. Regular visits give an opportunity for preventive care and patient education. For example, GPs can provide high-risk patients with “COVID treatment plans” as a reminder to get tested and seek treatment as soon as they are unwell. Difficulty seeing a GP could help explain low antiviral use in rural areas. Compared to people in major cities, people in small rural towns have about 35% <a href="https://hwd.health.gov.au/resources/data/gp-primarycare.html">fewer</a> GPs, see their GP about half as often, and are 30% more likely to <a href="https://www.abs.gov.au/statistics/health/health-services/patient-experiences/latest-release">report</a> waiting too long for an appointment. Just like for <a href="https://grattan.edu.au/wp-content/uploads/2023/11/A-fair-shot-How-to-close-the-vaccination-gap-Grattan-Institute-Report.pdf">vaccination</a>, a GP’s focus on antivirals probably matters, as does providing care that is accessible to people from different cultural backgrounds. <h2>Care should go those who need it</h2> Since the period we looked at, evidence has emerged that raises <a href="https://url.au.m.mimecastprotect.com/s/FmjFC91ZVBSmBpXpZSEh9CqMtQx?domain=nejm.org">doubts</a> about how effective antivirals are, particularly for people at lower risk of severe illness. That means getting vaccinated is more important than getting antivirals. But all Australians who are eligible for antivirals should have the same chance of getting them. These drugs have cost more than A$1.7 billion, with the vast majority of that money coming from the federal government. While dispensing rates have fallen, more than <a href="http://medicarestatistics.humanservices.gov.au/statistics/do.jsp?_PROGRAM=%2Fstatistics%2Fpbs_item_standard_report&itemlst=%2712910L%27%2C%2712996B%27&ITEMCNT=2&LIST=12910L%2C12996B&VAR=SERVICES&RPT_FMT=6&start_dt=202201&end_dt=202408">30,000</a> packs of COVID antivirals were dispensed in August, costing about $35 million. Such a huge investment shouldn’t be leaving so many people behind. Getting treatment shouldn’t depend on your income, cultural background or where you live. Instead, care should go to those who need it the most. People born overseas have been <a href="https://www.abs.gov.au/articles/covid-19-mortality-australia-deaths-registered-until-31-january-2024#deaths-due-to-covid-19-country-of-birth">40% more likely</a> to die from COVID than those born here. Indigenous Australians have been <a href="https://www.abs.gov.au/articles/covid-19-mortality-australia-deaths-registered-until-31-january-2024#covid-19-mortality-among-aboriginal-and-torres-strait-islander-people">60% more likely</a> to die from COVID than non-Indigenous people. And the most disadvantaged people have been <a href="https://www.abs.gov.au/articles/covid-19-mortality-australia-deaths-registered-until-31-january-2024#deaths-due-to-covid-19-socio-economic-status-seifa-">2.8 times</a> more likely to die from COVID than those in the wealthiest areas. All those at-risk groups have been more likely to miss out on antivirals. It’s not just a problem with antivirals. The same groups are also disproportionately missing out on COVID <a>vaccination</a>, compounding their risk of severe illness. The pattern is repeated for other important preventive health care, such as <a href="https://www.aihw.gov.au/getmedia/54a38a6a-9e3c-4f58-b2f6-cdef977a7d60/aihw-can-155_15sept.pdf?v=20230915162104&inline=true">cancer</a> <a href="https://www.aihw.gov.au/getmedia/27f32443-5206-4189-8775-0c1f55a26bc4/aihw-can-160.pdf?v=20240617095924&inline=true">screening</a>. <h2>A 3-step plan to meet patients’ needs</h2> The federal government should do three things to close these gaps in preventive care. First, the government should make Primary Health Networks (PHNs) responsible for reducing them. PHNs, the regional bodies responsible for improving primary care, should share data with GPs and step in to boost uptake in communities that are missing out. Second, the government should extend its <a href="https://www.health.gov.au/our-work/mymedicare">MyMedicare</a> reforms. MyMedicare gives general practices flexible funding to care for patients who live in residential aged care or who visit hospital frequently. That approach should be <a href="https://grattan.edu.au/report/a-new-medicare-strengthening-general-practice/">expanded</a> to all patients, with more funding for poorer and sicker patients. That will give GP clinics time to advise patients about preventive health, including COVID vaccines and antivirals, before they get sick. Third, team-based pharmacist prescribing should be introduced. Then pharmacists could quickly dispense antivirals for patients if they have a prior agreement with the patient’s GP. It’s an approach that would also <a href="https://theconversation.com/pharmacists-should-be-able-to-work-with-gps-to-prescribe-medicines-for-long-term-conditions-212359">work</a> for medications for chronic diseases, such as cardiovascular disease. COVID antivirals, unlike vaccines, have been <a href="https://theconversation.com/covid-wave-whats-the-latest-on-antiviral-drugs-and-who-is-eligible-in-australia-218423">keeping up</a> with new variants without the need for updates. If a new and more harmful variant emerges, or when a new pandemic hits, governments should have these systems in place to make sure everyone who needs treatment can get it fast. In the meantime, fairer access to care will help close the big and persistent <a href="https://www.aihw.gov.au/getmedia/0cbc6c45-b97a-44f7-ad1f-2517a1f0378c/hiamhbrfhsu.pdf?v=20230605184558&inline=true">gaps</a> in health between different groups of Australians. <a href="https://theconversation.com/profiles/peter-breadon-1348098">Peter Breadon</a>, Program Director, Health and Aged Care, <a href="https://theconversation.com/institutions/grattan-institute-1168">Grattan Institute</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Daylight savings is about to start. But why do the days get longer?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/laura-nicole-driessen-892965">Laura Nicole Driessen</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> The days are getting longer and in Australia, the switch to daylight saving time is almost upon us (for about 70% of the population, anyway). But why do we have longer days in summer and shorter days in winter? <h2>It’s all about the tilt</h2> Earth goes around the Sun in an almost circular orbit. But not everything is lined up perfectly. Earth’s axis is tilted by 23.44 degrees relative to its orbit around the Sun. Imagine Earth’s orbit as a flat frisbee with the Sun in the middle and Earth as a ball on a stick going around the edge. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/623235/original/file-20241003-16-xourdg.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/623235/original/file-20241003-16-xourdg.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/623235/original/file-20241003-16-xourdg.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=400&fit=crop&dpr=1 600w, https://images.theconversation.com/files/623235/original/file-20241003-16-xourdg.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=400&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/623235/original/file-20241003-16-xourdg.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=400&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/623235/original/file-20241003-16-xourdg.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=503&fit=crop&dpr=1 754w, https://images.theconversation.com/files/623235/original/file-20241003-16-xourdg.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=503&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/623235/original/file-20241003-16-xourdg.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=503&fit=crop&dpr=3 2262w" alt="Diagram of Earth's rotation around the sun." /></a><figcaption>Earth goes around the Sun in an almost circular orbit. <a class="source" href="https://www.shutterstock.com/image-vector/earths-orbit-earth-rotation-around-sun-2441275921">Angela Cini/Shutterstock</a></figcaption></figure> If Earth’s axis wasn’t tilted (if its tilt was zero degrees) the stick would be exactly perpendicular to the frisbee. If you grab that perpendicular stick and tip it 23.44 degrees sideways, that’s what Earth’s tilt looks like now. As Earth orbits the Sun, the tilt of the stick does not rotate relative to the Sun. If you were in outer space looking at the Sun and you watched from the exact same position for a whole year, you would see Earth go around the Sun while the stick stayed tilted the same direction. In other words, if the top of the stick was pointing to the right when you started watching Earth go around the Sun, it would stay pointing to the right the whole way around. This tilt gives us longer days in summer and shorter days in winter. Let’s set up the scenario so the Northern Hemisphere is the top of the planet and the Southern Hemisphere is the bottom of the planet. When Earth is on one side of the Sun, the top of the stick is pointed towards the Sun. This is summer in the Northern Hemisphere and winter in the Southern Hemisphere. Six months later, when Earth is on the other side of the Sun, the bottom of the stick is pointed towards the Sun – and the seasons are reversed. <h2>Solstices and equinoxes</h2> Those two points, when the top of the stick is pointing directly towards the Sun or directly away from the Sun, are the solstices. They are the longest and shortest days of the year, depending on your hemisphere. The shortest day of 2024 in Australia was June 21. Looking forward to sunnier times, the longest day of the year in 2024 will be December 21. In between the summer and winter solstice, we have the equinoxes – when days and nights are almost exactly the same length. Those are the days when the stick through Earth is “side-on” to the Sun. The equinox is also the day when the Sun passes directly over Earth’s equator. In 2024 this happened on March 20 at 2:06pm AEDT and September 22 at 10:43pm AEST. That means that since September 22, days have been getting longer than nights in the Southern Hemisphere. <h2>What does daylight savings do?</h2> Earth’s tilt means the Sun both rises earlier and sets later as we head towards summer. When the clocks (in some states) switch to daylight saving time, people in these states all get one hour less of sleep. However, the total length of the day doesn’t change just because we changed our clocks. For me, daylight savings means I need an extra cup of coffee in the morning for about a week before I adjust to the daylight savings-lag (like jet lag, but without the fun of travel). What it really gives us is more daylight in the evening, instead of more daylight in the morning. If you’re already a morning person, this isn’t the way to go. But if you prefer to have a long dinner in the summer sun it’s ideal. <h2>Has it always been this way?</h2> Earth’s axis hasn’t always been tilted at 23.44 degrees. It cycles from a minimum 22.1 degree tilt to a maximum 24.5 degree tilt and back again once every approximately 41,000 years. Earth’s axis also “precesses”, where the stick through it draws a circle once every approximately 26,000 years. You can see this in the animation below. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/622704/original/file-20241001-16-lh8pl9.gif?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/622704/original/file-20241001-16-lh8pl9.gif?ixlib=rb-4.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/622704/original/file-20241001-16-lh8pl9.gif?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=600&fit=crop&dpr=1 600w, https://images.theconversation.com/files/622704/original/file-20241001-16-lh8pl9.gif?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=600&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/622704/original/file-20241001-16-lh8pl9.gif?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=600&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/622704/original/file-20241001-16-lh8pl9.gif?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=754&fit=crop&dpr=1 754w, https://images.theconversation.com/files/622704/original/file-20241001-16-lh8pl9.gif?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=754&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/622704/original/file-20241001-16-lh8pl9.gif?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=754&fit=crop&dpr=3 2262w" alt="A gif of the Earth wobbling in a circle on its axis." /></a><figcaption>Demonstration of the precession of Earth’s axis. <a class="source" href="https://science.nasa.gov/resource/axial-precession-wobble/">NASA/JPL-Caltech</a></figcaption></figure> The length of a day on Earth hasn’t always been the same, either. At the moment, the length of a day is nearly exactly 24 hours. But it’s shifting all the time by tiny amounts. This is tracked very closely by a system of telescopes and satellites. These systems measure “<a href="https://ggos.org/item/earth-orientation-parameter/#:%7E:text=Accordingly%2C%20the%20EOP%20describe%20the,as%20tides%20and%20continental%20drift">Earth orientation parameters</a>” that describe Earth’s exact orientation compared to the position of stars in the sky. These are important to astronomers because the exact location of our telescopes is important for creating accurate maps of the sky. On top of all of this, the gravitational drag from the Moon causes days to become longer by around 2.3 milliseconds every 100 years. A few billion years ago, Earth’s day was a lot shorter – <a href="https://www.earthscope.org/news/a-day-is-not-always-24-hours-how-earths-shifting-systems-cause-day-length-variation/#:%7E:text=Billions%20of%20years%20ago%2C%20the,to%20the%20day%20every%20century">only 19 hours long</a>. Even though some of us are losing an hour of sleep this weekend, at least we get to enjoy 2.3 milliseconds longer every day than our great – and great-great – grandparents did.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/240221/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/laura-nicole-driessen-892965">Laura Nicole Driessen</a>, Postdoctoral researcher in radio astronomy, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

High-speed rail plans may finally end Australia’s 40-year wait to get on board

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/philip-laird-3503">Philip Laird</a>, <a href="https://theconversation.com/institutions/university-of-wollongong-711">University of Wollongong</a> Australia has debated and studied high-speed rail for four decades. The High Speed Rail Authority has begun <a href="https://www.hsra.gov.au/project">work on a project</a> that could finally deliver some high-speed rail in the 2030s. The Albanese government set up the authority in 2022. It also committed A$500 million to plan and protect a high-speed rail corridor between Sydney and Newcastle. This corridor was prioritised due to significant capacity constraints on the existing line, among other reasons. The ultimate plan is for a high-speed rail network to connect Brisbane, Sydney, Canberra, Melbourne and regional communities across the east coast. The network would help Australia in its urgent task to reduce greenhouse gas emissions from transport. These <a href="https://www.infrastructure.gov.au/infrastructure-transport-vehicles/towards-net-zero-transport-and-infrastructure">continue to increase</a> even as emissions from other sectors fall. The authority has now publicly outlined plans for the first stage of this east coast network. After a history of failed proposals dating back to 1984, the new plans provide some cause for optimism that Australia could have some high-speed rail by 2037. <h2>What is high-speed rail and why do we need it?</h2> The International Rail Union of Railways <a href="https://uic.org/passenger/highspeed">defines high-speed rail</a> as new lines designed for speeds of 250km/h or more and upgraded lines for speeds of at least 200km/h. High-speed rail could greatly reduce transport emissions by replacing <a href="https://theconversation.com/wondering-how-to-get-from-brisbane-to-melbourne-without-wrecking-the-climate-our-transport-choices-make-a-huge-difference-237396">air travel in particular</a>. For example, the <a href="https://www.bitre.gov.au/publications/ongoing/domestic_airline_activity-monthly_publications">7.92 million passengers</a> flying between Melbourne and Sydney in 2023-24 produced about 1.5 million tonnes of emissions. Including <a href="https://theconversation.com/how-air-travellers-can-cut-their-door-to-door-emissions-right-now-by-as-much-as-13-on-the-sydney-melbourne-route-211099">travel to and from airports</a> and other flight routes along the corridor (Sydney or Melbourne to Canberra, Albury etc), this adds up to about 2% of <a href="https://www.dcceew.gov.au/climate-change/strategies/annual-climate-change-statement-2023">annual domestic transport emissions</a>. A Sydney–Melbourne high-speed rail link could cut emissions to a fraction of those from <a href="https://theconversation.com/wondering-how-to-get-from-brisbane-to-melbourne-without-wrecking-the-climate-our-transport-choices-make-a-huge-difference-237396">air</a> and <a href="https://theconversation.com/we-compared-land-transport-options-for-getting-to-net-zero-hands-down-electric-rail-is-the-best-234092">road</a> transport. If Australia is to achieve <a href="https://www.dcceew.gov.au/climate-change/emissions-reduction/net-zero">net zero by 2050</a>, a <a href="https://theconversation.com/we-compared-land-transport-options-for-getting-to-net-zero-hands-down-electric-rail-is-the-best-234092">shift to rail will be essential</a>. High-speed city-to-city rail services will be needed to become an attractive alternative to air travel. <h2>What is the authority working on?</h2> Early this year the High Speed Rail Authority gained a new CEO, Tim Parker, with extensive experience in delivering mega-projects. In late August, the authority outlined its plans at an industry briefing in Newcastle. The authority has commissioned eight studies, including a business case for a Sydney–Newcastle line. Significantly, it will include the cost of future highway upgrades if high-speed rail does not proceed. This study, along with a report on how high-speed rail will proceed along Australia’s east coast, is due by the end of this year. Also under way is a <a href="https://minister.infrastructure.gov.au/c-king/media-release/all-aboard-high-speed-rail-accelerates-first-investigation-works">geotechnical study</a> that includes drilling 27 boreholes. It will help determine the proposed depths of two long rail tunnels and guide decisions on crossing the Hawkesbury River and the route to the Central Coast and on to Newcastle. All going well, including land acquisition and agreements with the New South Wales government (which could include funding), work could <a href="https://www.newcastleherald.com.au/story/8743698/newcastle-high-speed-rail-possible-by-2037-as-tunnel-plan-emerges">start in 2027 and be completed by 2037</a>. <h2>Many questions remain</h2> Given the time and money required to deliver a Sydney–Newcastle line, bipartisan support will be needed. However, the federal opposition is yet to make a clear commitment to high-speed rail. There are other uncertainties too. Will the trains be operated by the public or private sector? The latter was the intention for projects that were scrapped decades ago, such as the CSIRO-proposed Very Fast Train (<a href="http://www.repositoryofideas.com/VFT_information.html">VFT</a>) linking Sydney, Canberra and Melbourne, and the Sydney–Canberra <a href="https://trid.trb.org/View/1203853">Speedrail</a>. And how will the engineering projects be delivered? The new authority must learn from the project management <a href="https://www.infrastructure.gov.au/department/media/news/independent-review-inland-rail-released">problems in delivering the Inland Rail</a> freight line. The project is running late and costs have blown out. Some major federally funded government projects have worked well. These include upgrades of the national highway system (by state road authorities and contractors) and the new <a href="https://www.westernsydneyairport.gov.au/">Western Sydney International Airport</a>, which is nearing completion. <h2>And what about a full Sydney–Melbourne line?</h2> The big question is when work will start on a Sydney–Melbourne high-speed rail service. In 2019, International High-Speed Rail Association chairman <a href="https://ara.net.au/media-release/ausrailplus-2019-conference-exhibition-3-5-december-2019-in-sydney/">Masafumi Shukuri estimated</a> building this line could take 20 years. The present line is 60km longer than it should be as the route dates back to the steam age. It also has far too many tight curves. This means train travel on this line is slower than cars and trucks. As former NSW State Rail chief Len Harper <a href="https://theconversation.com/more-than-ever-its-time-to-upgrade-the-sydney-melbourne-railway-187169">said</a> in 1995, this railway was already “inadequate for current and future needs” even back then. When the VFT was proposed in 1984, questions were raised as to whether our population was big enough for such a project. Now, more than 15.5 million people live in NSW, Victoria and the Australian Capital Territory. Melbourne–Sydney is the <a href="https://www.smh.com.au/traveller/travel-news/the-world-s-busiest-flight-routes-and-airports-revealed-20231222-p5et7n.html">world’s fifth-busiest flight route</a>. Advocacy group Fastrack Australia <a href="https://www.fastrackaustralia.net/hsr-implementation-plan">has called</a> for a Sydney–Melbourne track built to high-speed standards and able to carry freight. The estimated travel time is four hours. This group and the <a href="https://www.railfutures.org.au/category/submissions/%20July%202024%20reducing%20emissions%20in%20freight">Rail Futures Institute</a> propose the line be built in stages, with priority given to the section from near Macarthur to Mittagong in NSW. This would reduce the current line’s length by about 18km and allow for better Sydney–Canberra train services. Urgent action is needed to protect the rail corridor from encroaching urban development. <h2>Australia needs to catch up</h2> In June 2023, when the new authority started work, I <a href="https://theconversation.com/can-the-new-high-speed-rail-authority-deliver-after-4-decades-of-costly-studies-206287">observed</a> that Australia must surely hold the world record for studies into high-speed rail with no construction. In stark contrast, this October marks the 60th anniversary of the world’s first dedicated high-speed rail line, the Tokaido Shinkansen in Japan linking Tokyo to Shin-Osaka. The network has since grown in stages to about 3,000km of lines. Today, high-speed rail <a href="https://uic.org/passenger/highspeed/article/high-speed-data-and-atlas">operates in 21 countries</a> over about 60,000km of lines – China has about 40,000km. Indonesia’s high-speed rail service between Jakarta and Bandung started running last year. India and Thailand are in the advanced stages of delivering high-speed rail. It’s also under construction in another 11 countries. Australia could finally join them in the next few years if it starts building the Sydney–Newcastle line.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/238232/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/philip-laird-3503">Philip Laird</a>, Honorary Principal Fellow, <a href="https://theconversation.com/institutions/university-of-wollongong-711">University of Wollongong</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

How you can get the official Australian portraits of The King and Queen

Royal fans nationwide can now request a special keepsake online for free. All Australians are entitled to their very own free portrait of King Charles and Queen Camilla. The way one can obtain the monarchy keepsake is through sending an email to their local federal MP requesting one. The initiative comes under the constituents' request program, which allows registered Australian voters to receive their own printed portrait of the royals. Official portraits of the King and Queen were provided to the Australian Government by Buckingham Palace in July and are available for public access. Photos available include a photo of the royal couple standing together, and seperate ones of the monarch and her majesty posing alone. In the photos the King and Queen both donned royal blue outfits and their Commonwealth Insignia, with the King wearing The Sovereign's Badge of the Order of Australia and the Queen wearing the Wattle Brooch. The portraits were taken by royal photographer Millie Pilkington in Buckingham Palace's White Drawing Room in June. The digital images can be downloaded for free from the Department of the Prime Minister and Cabinet <a href="https://www.pmc.gov.au/government/official-australian-portraits-king-and-queen" target="_blank" rel="noopener">website</a> for private use. Those who want a physical copy can request printed versions through their Federal Member of the House of Representatives or Senator in their state or territory via email. The government-funded program, introduced in the Parliamentary Entitles Act 1990, is available for Australian citizens only. Image: Department of the Prime Minister and Cabinet/ Millie Pilkington

The internet is worse than it used to be. How did we get here, and can we go back?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/marc-cheong-998488">Marc Cheong</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> and <a href="https://theconversation.com/profiles/wonsun-shin-1300054">Wonsun Shin</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> When it comes to our experience of the internet, “the times, <a href="https://en.wikipedia.org/wiki/The_Times_They_Are_a-Changin%27_(song)">they are a-changin’</a>”, as Bob Dylan would say. You can’t quite recall how, but the internet certainly feels different these days. To some, it is “<a href="https://www.npr.org/2024/01/16/1224878097/everyday-users-are-complaining-that-the-internet-is-more-chaotic-than-ever">less fun and less informative</a>” than it used to be. To others, online searches are made up of “<a href="https://www.theverge.com/c/23998379/google-search-seo-algorithm-webpage-optimization?src=longreads">cookie cutter</a>” pages that drown out useful information and are saturated with scams, spam and content generated by artificial intelligence (AI). Your social media feeds are full of eye-catching, provocative, hyper-targeted, or anger-inducing content, from <a href="https://theconversation.com/the-dead-internet-theory-makes-eerie-claims-about-an-ai-run-web-the-truth-is-more-sinister-229609">bizarre AI-generated imagery</a> to robot-like comments. You’re lucky if your video feeds are not solely made up of exhortations to “subscribe”. How did we get here? And can we claw our way back? <h2>Commercial interests rule</h2> One major factor contributing to the current state of the internet is its over-commercialisation: financial motives drive much of the content. This has arguably led to the prevalence of sensationalism, prioritising virality over information quality. Covert and deceptive advertising is widespread, blurring the line between commercial and non-commercial content to attract more attention and engagement. Another driving force is the dominance of tech giants like Google, Meta and Amazon. They reach billions worldwide and wield immense power over the content we consume. Their platforms use advanced tracking technologies and opaque algorithms to generate hyper-targeted media content, powered by extensive user data. This creates <a href="https://www.campaignasia.com/article/the-echo-chamber-effect-how-algorithms-shape-our-worldview/491762">filter bubbles</a>, where users are exposed to limited content that reinforces their existing beliefs and biases, and <a href="https://philarchive.org/archive/NGUECA">echo chambers</a> where other viewpoints are actively discredited. Bad actors like <a href="https://abcnews.go.com/Technology/ai-fuel-financial-scams-online-industry-experts/story?id=103732051">cyber criminals and scammers</a> have been an enduring problem online. However, evolving technology like generative AI has further empowered them, enabling them to create highly realistic fake images, deepfake videos and <a href="https://www.newyorker.com/science/annals-of-artificial-intelligence/the-terrifying-ai-scam-that-uses-your-loved-ones-voice">voice cloning</a>. AI’s ability to automate content creation has also flooded the internet with low-quality, misleading and harmful material at an unprecedented scale. In sum, the accelerated commercialisation of the internet, the dominance of media tech giants and the presence of bad actors have infiltrated content on the internet. The rise of AI further intensifies this, making the internet more chaotic than ever. <h2>Some of the ‘good’ internet remains</h2> So, what was the “good internet” some of us long for with nostalgia? At the outset, the internet was meant to be a free egalitarian space people were meant to “surf” and “browse”. Knowledge was meant to be shared: sites such as Wikipedia and The Internet Archive are continuing bastions of knowledge. Before the advent of filter bubbles, the internet was a creative playground where people explored different ideas, discussed varying perspectives, and collaborated with individuals from “outgroups” – those outside their social circles who may hold opposing views. Early social media platforms were built on the ethos of reconnecting with long-lost classmates and family members. Many of us have community groups, acquaintances and family we reach out to via the internet. The “connection” aspect of the internet remains as important as ever – as we all saw during the COVID pandemic. What else do we want to preserve? Privacy. A New Yorker cartoon joke in 1993 stated that “<a href="https://web.archive.org/web/20051029045942/http://www.unc.edu/depts/jomc/academics/dri/idog.html">on the internet, nobody knows you’re a dog</a>”. Now everyone – especially advertisers – wants to know who you are. To quote the <a href="https://www.oaic.gov.au/privacy/your-privacy-rights/your-personal-information/what-is-privacy">Office of the Australian Information Commissioner</a>, one of the tenets of privacy is “to be able to control who can see or use information about you”. At the very least, we want to control what big tech knows about us, especially if they could stand to profit from it. <h2>Can we ever go back?</h2> We can’t control “a changin’” times, but we can keep as much of the good parts as we can. For starters, we can vote with our feet. Users can enact change and bring awareness to problems on existing platforms. In recent times, we have seen this with the <a href="https://theconversation.com/thinking-of-breaking-up-with-twitter-heres-the-right-way-to-do-it-195002">exodus of users</a> from X (formerly Twitter) to other platforms, and the <a href="https://www.economist.com/the-economist-explains/2023/06/26/why-reddit-users-are-protesting-against-the-sites-leadership">platform-wide protest against Reddit</a> for changing its third-party data access policies. However, voting with our feet is only possible when there’s competition. In the case of X, various other platforms – from Mastodon to Threads to Bluesky – enable users to pick one that aligns with their preferences, values and social circles. Search engines have alternatives, too, such as DuckDuckGo or Ecosia. But competition can only be created by moving to decentralised systems and removing monopolies. This actually happened in the early days of the internet during the 1990s “<a href="https://thehistoryoftheweb.com/browser-wars/">browser wars</a>”, when Microsoft was eventually accused of illegally monopolising the web browser market in <a href="https://en.wikipedia.org/wiki/United_States_v._Microsoft_Corp.">a landmark court case</a>. As users of technology, all of us must remain vigilant about threats to our privacy and knowledge. With cheap and ubiquitous generative AI, misleading content and scams are more realistic as ever. We must exercise healthy scepticism and ensure those most at risk from online threats – such as children and older people – are educated about potential harms. Remember, the internet is not optimised for your best interests. It’s up to you to decide how much power you give to the tech giants who are fuelling theirs.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/236513/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/marc-cheong-998488">Marc Cheong</a>, Senior Lecturer of Information Systems, School of Computing and Information Systems; and (Honorary) Senior Fellow, Melbourne Law School, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> and <a href="https://theconversation.com/profiles/wonsun-shin-1300054">Wonsun Shin</a>, Associate Professor in Media and Communications, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Outrage as Paralympian gets disqualified for "unfair" reason

Elena Congost, had just finished the T12/B2 run in third place, but was disqualified and had the bronze medal taken from her, for this one simple move. The 36-year-old was running in the vision-impaired category with guide Mia Carol Bruguera. When her guide faltered with a cramp in the final metres before the finish line, Congost instinctively helped him from falling over and let go of the rope that binds them together. This is not allowed within Paralympic rules as all runners must be connected to their guide via a tether. As a result, Japan’s Misato Michishita was elevated to the bronze medal after finishing fourth. In a heartbreaking interview after the race, a devastated Congost said: “It’s unfair, surreal.” “The next athlete was three minutes behind me. It was just a reflex action that any human being would have done – holding on to someone who is falling.” “But that doesn’t mean that there is any kind of benefit or help. In fact, it is clear that I stop dead. “I can’t find any explanation for this. It’s sad because, in addition, I had just been without a scholarship. And I’m not going to get one now. They will leave me out of everything again when I have shown everything I can do. “I have not been disqualified for cheating, but for being a person, for helping someone.” In a separate interview with Spanish outlet Marca, she said that despite being disqualified, she is proud of her actions. “I would like everyone to know that I have not been disqualified for cheating, but rather I have been disqualified for being a person and for an instinct that comes to you when someone is falling and is to help or support them,” she said. “I’m devastated, to be honest, because I had the medal. I’m super proud of everything I’ve done and in the end they disqualify me because 10 metres from the finish line I let go of the rope for a second because a person next to me fell face first to the ground and I grabbed the rope again and we crossed the finish line. “The next athlete is three minutes away from me, so it was a reflex action of any human being to hold on to a person who is falling next to you.” Fans around the world were outraged at the disqualification verdict and have called for officials to overturn it. “Shame on you. Give the medal back to Elena Congost,” one fan wrote on X, formerly Twitter. “Where is the Olympic spirit? Elena Congost was disqualified after running 42km and helping her guide not to fall to the ground. She has lost the bronze medal and her sports scholarship. Disgusting," another wrote. "Give the medal to Elena Congost. This decision ruins the paralympics. How can you be called inclusive if you can’t help a person from falling?” a third added. Image: X

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/sathana-dushyanthen-1169328">Sathana Dushyanthen</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> It has been a long winter, filled with many viruses and cost-of-living pressures, on top of the usual mix of work, study, life admin and caring responsibilities. Stress is an inevitable part of life. In short bursts, our stress response has evolved as a survival mechanism to help us be more alert in <a href="https://theconversation.com/no-you-cant-blame-all-your-health-issues-on-high-cortisol-heres-how-the-hormone-works-203162">fight or flight situations</a>. But when stress is chronic, it weakens the immune system and makes us more vulnerable to illnesses such as the <a href="https://www.healthline.com/health/can-stress-make-you-sick#:%7E:text=The%20common%20cold&text=Inflammation%20has%20been%20linked%20to,to%20the%20cold%2Dcausing%20germs.">common cold</a>, <a href="https://journals.lww.com/psychosomaticmedicine/abstract/1999/03000/psychological_stress,_cytokine_production,_and.9.aspx">flu</a> and <a href="https://onlinelibrary.wiley.com/doi/abs/10.1002/smi.3017">COVID</a>. <h2>Stress makes it harder to fight off viruses</h2> When the immune system starts to break down, a virus that would normally have been under control starts to flourish. Once you begin to feel sick, the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4465119/">stress response</a> rises, making it harder for the immune system to fight off the disease. You may be sick more often and for longer periods of time, without enough immune cells primed and ready to <a href="https://link.springer.com/chapter/10.1007/978-3-030-16996-1_6">fight</a>. In the 1990s, American psychology professor Sheldon Cohen and his colleagues conducted a number of <a href="https://www.cmu.edu/common-cold-project/">studies</a> where healthy people were exposed to an upper respiratory infection, through drops of virus placed directly into their <a href="https://www.nejm.org/doi/full/10.1056/NEJM199108293250903">nose</a>. These participants were then quarantined in a hotel and monitored closely to determine who became <a href="https://theconversation.com/stress-less-it-might-protect-you-from-covid-153361">ill</a>. One of the most important factors predicting who got sick was prolonged psychological <a href="https://journals.sagepub.com/doi/full/10.1177/1745691620942516">stress</a>. <h2>Cortisol suppresses immunity</h2> “Short-term stress” is stress that lasts for a period of minutes to hours, while “chronic stress” persists for several hours per day for <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5964013/#:%7E:text=Therefore%2C%20a%20major%20distinguishing%20characteristic,weeks%20or%20months%20%5B9%5D.">weeks or months</a>. When faced with a perceived threat, psychological or physical, the hypothalamus region of the brain sets off an alarm system. This signals the release of a surge of hormones, including adrenaline and <a href="https://www.embopress.org/doi/full/10.15252/msb.20209510">cortisol</a>. <figure class="align-center "><img src="https://images.theconversation.com/files/616892/original/file-20240903-18-blrqoz.png?ixlib=rb-4.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/616892/original/file-20240903-18-blrqoz.png?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=472&fit=crop&dpr=1 600w, https://images.theconversation.com/files/616892/original/file-20240903-18-blrqoz.png?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=472&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/616892/original/file-20240903-18-blrqoz.png?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=472&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/616892/original/file-20240903-18-blrqoz.png?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=593&fit=crop&dpr=1 754w, https://images.theconversation.com/files/616892/original/file-20240903-18-blrqoz.png?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=593&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/616892/original/file-20240903-18-blrqoz.png?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=593&fit=crop&dpr=3 2262w" alt="Human brain illustration" /><figcaption>The hypothalamus sets off an alarm system in response to a real or perceived threat. <a class="source" href="https://www.shutterstock.com/image-illustration/hypothalamus-causes-vasoconstriction-illustration-medical-brain-435142264">stefan3andrei/Shutterstock</a></figcaption></figure> In a typical stress response, <a href="https://www.sciencedirect.com/science/article/abs/pii/S147149060300173X">cortisol levels</a> quickly increase when stress occurs, and then rapidly drop back to normal once the stress has subsided. In the short term, cortisol suppresses inflammation, to ensure the body has enough energy available to respond to an <a href="https://www.frontiersin.org/journals/immunology/articles/10.3389/fimmu.2019.00245/full">immediate threat</a>. But in the longer term, chronic stress can be harmful. A Harvard University study <a href="https://jamanetwork.com/journals/jamapsychiatry/fullarticle/2796097">from 2022</a> showed that people suffering from psychological distress in the lead up to their COVID infection had a greater chance of experiencing long COVID. They <a href="https://jamanetwork.com/journals/jamapsychiatry/fullarticle/2796097">classified</a> this distress as depression, probable anxiety, perceived stress, worry about COVID and loneliness. Those suffering distress had close to a <a href="https://jamanetwork.com/journals/jamapsychiatry/fullarticle/2796097">50% greater risk</a> of long COVID compared to other <a href="https://theconversation.com/being-stressed-out-before-you-get-covid-increases-your-chances-of-long-covid-heres-why-190649">participants</a>. Cortisol has been shown to be high in the most severe cases of <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7102614/">COVID</a>. <h2>Stress causes inflammation</h2> <a href="https://stories.uq.edu.au/imb/the-edge/inflammation/what-is-inflammation/index.html">Inflammation</a> is a short-term reaction to an injury or infection. It is responsible for trafficking immune cells in your body so the right cells are present in the right locations at the right times and at the right <a href="https://link.springer.com/article/10.1007/s12026-014-8517-0">levels</a>. The immune cells also store a memory of that threat to respond faster and more effectively the next <a href="https://theconversation.com/being-stressed-out-before-you-get-covid-increases-your-chances-of-long-covid-heres-why-190649">time</a>. Initially, circulating immune cells detect and flock to the site of <a href="https://www.nature.com/articles/ni1275">infection</a>. Messenger proteins, known as pro-inflammatory cytokines, are released by immune cells, to signal the danger and recruit help, and our immune system responds to neutralise the <a href="https://stories.uq.edu.au/imb/the-edge/inflammation/what-is-inflammation/index.html">threat</a>. During this response to the infection, if the immune system produces too much of these inflammatory chemicals, it can trigger symptoms such as nasal congestion and runny <a href="https://journals.sagepub.com/doi/full/10.1177/1745691620942516">nose</a>. <h2>What about chronic stress?</h2> Chronic stress causes persistently high cortisol secretion, which remains high even in the absence of an immediate <a href="https://theconversation.com/no-you-cant-blame-all-your-health-issues-on-high-cortisol-heres-how-the-hormone-works-203162">stressor</a>. The immune system becomes desensitised and unresponsive to this <a href="https://www.sciencedirect.com/science/article/abs/pii/S1043661816307435">cortisol suppression</a>, increasing low-grade “silent” inflammation and the production of pro-inflammatory cytokines (the messenger proteins). Immune cells become exhausted and start to <a href="https://www.fxmedicine.com.au/blog-post/adrenal-immune-connection">malfunction</a>. The body loses the ability to turn down the inflammatory <a href="https://journals.sagepub.com/doi/full/10.1177/1745691620942516">response</a>. Over time, the immune system changes the way it responds by reprogramming to a “<a href="https://www.unimelb.edu.au/newsroom/news/2021/april/how-stress-can-stop-immune-cells-in-their-tracks">low surveillance mode</a>”. The immune system misses early opportunities to destroy threats, and the process of recovery can take <a href="https://theconversation.com/being-stressed-out-before-you-get-covid-increases-your-chances-of-long-covid-heres-why-190649">longer</a>. <h2>So how can you manage your stress?</h2> We can actively strengthen our immunity and natural defences by managing our <a href="https://theconversation.com/stuck-in-fight-or-flight-mode-5-ways-to-complete-the-stress-cycle-and-avoid-burnout-or-depression-218599">stress levels</a>. Rather than letting stress build up, try to address it early and frequently by: 1) Getting enough sleep Getting enough sleep reduces <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3132857/">cortisol levels</a> and inflammation. During sleep, the immune system <a href="https://link.springer.com/chapter/10.1007/978-1-4939-6578-6_12">releases</a> <a href="https://theconversation.com/sleep-wont-cure-the-coronavirus-but-it-can-help-our-bodies-fight-it-134674">cytokines</a>, which help fight infections and inflammation. 2) Taking regular exercise Exercising helps the lymphatic system (which balances bodily fluids as part of the immune system) circulate and allows immune cells to monitor for threats, while sweating flushes <a href="https://www.healthline.com/nutrition/does-exercise-boost-immune-system">toxins</a>. Physical activity also lowers stress hormone levels through the release of positive brain <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7387807/">signals</a>. 3) Eating a healthy diet Ensuring your diet contains enough nutrients – such as the B vitamins, and the full breadth of minerals like magnesium, iron and zinc – during times of stress has a positive impact on overall stress <a href="https://www.ncbi.nlm.nih.gov/pubmed/22782571">levels</a>. Staying hydrated helps the body to flush out <a href="https://theconversation.com/a-strong-immune-system-helps-ward-off-colds-and-flus-but-its-not-the-only-factor-99512">toxins</a>. 4) Socialising and practising meditation or mindfulness These activities increase endorphins and serotonin, which improve mood and have <a href="https://www.sciencedirect.com/science/article/pii/S2949834123000351">anti-inflammatory effects</a>. Breathing exercises and meditation stimulate the parasympathetic nervous system, which calms down our stress responses so we can “reset” and reduce <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4940234/">cortisol levels</a>.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/237456/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/sathana-dushyanthen-1169328">Sathana Dushyanthen</a>, Academic Specialist & Lecturer in Cancer Sciences & Digital Health| Superstar of STEM| Science Communicator, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Strength training has a range of benefits for women. Here are 4 ways to get into weights

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/erin-kelly-1497598">Erin Kelly</a>, <a href="https://theconversation.com/institutions/university-of-canberra-865">University of Canberra</a> Picture a gym ten years ago: the weights room was largely a male-dominated space, with women mostly doing cardio exercise. Fast-forward to today and you’re likely to see women of all ages and backgrounds confidently navigating weights equipment. This is more than just anecdotal. According to data from the <a href="https://app.powerbi.com/view?r=eyJrIjoiZGU1YWFhZDgtMmRhZi00YTgyLThhMzItYjc2ODk5NTg0MTg1IiwidCI6IjhkMmUwZjRjLTU1ZjItNGNiMS04ZWU3LWRhNWRkM2ZmMzYwMCJ9">Australian Sports Commission</a>, the number of women <a href="https://www.clearinghouseforsport.gov.au/research/ausplay/results#portal">participating in weightlifting</a> (either competitively or not) grew nearly five-fold between 2016 and 2022. Women are discovering what research has long shown: strength training offers benefits beyond sculpted muscles. <h2>Health benefits</h2> <a href="https://www.womenshealth.gov/a-z-topics/osteoporosis">Osteoporosis</a>, a disease in which the bones become weak and brittle, affects more women than men. Strength training increases <a href="https://www.mayoclinic.org/healthy-lifestyle/fitness/in-depth/strength-training/art-20046670">bone density</a>, a crucial factor for <a href="https://bmcmedicine.biomedcentral.com/articles/10.1186/1741-7015-8-47">preventing osteoporosis</a>, especially for women negotiating menopause. Strength training also improves <a href="http://link.springer.com/10.1007/s40279-015-0379-7">insulin sensitivity</a>, which means your body gets better at using insulin to manage blood sugar levels, reducing the risk of type 2 diabetes. Regular strength training contributes to better <a href="https://doi.org/10.1139/apnm-2020-0245">heart health</a> too. There’s a mental health boost as well. Strength training has been linked to reduced symptoms of <a href="https://doi.org/10.1001/jamapsychiatry.2018.0572">depression</a> and <a href="http://link.springer.com/10.1007/s40279-017-0769-0">anxiety</a>. <h2>Improved confidence and body image</h2> Unlike some forms of exercise where progress can feel elusive, strength training offers clear and tangible measures of success. Each time you add more weight to a bar, you are reminded of your ability to meet your goals and <a href="https://www.tandfonline.com/doi/full/10.1080/2159676X.2019.1634127">conquer challenges</a>. This sense of achievement doesn’t just stay in the gym – it can change how women see themselves. A <a href="https://linkinghub.elsevier.com/retrieve/pii/S1755296623000194">recent study</a> found women who regularly lift weights often feel more empowered to make positive changes in their lives and feel ready to face life’s challenges outside the gym. Strength training also has the potential to positively impact <a href="https://journals.lww.com/nsca-jscr/abstract/2002/11000/Relations_of_Strength_Training_to_Body_Image_Among.25.aspx">body image</a>. In a world where women are often judged on appearance, lifting weights can shift the focus <a href="http://journals.sagepub.com/doi/10.1177/0193732502238256">to function</a>. Instead of worrying about the number on the scale or fitting into a certain dress size, women often come to appreciate their bodies for what they can do. “Am I lifting more than I could last month?” and “can I carry all my groceries in a single trip?” may become new measures of physical success. Lifting weights can also be about challenging outdated ideas of how women “should” be. Qualitative <a href="https://journals.humankinetics.com/view/journals/wspaj/aop/article-10.1123-wspaj.2022-0088/article-10.1123-wspaj.2022-0088.xml">research</a> I conducted with colleagues found that, for many women, strength training becomes a powerful form of rebellion against unrealistic beauty standards. As one participant told us: <blockquote> I wanted something that would allow me to train that just didn’t have anything to do with how I looked. </blockquote> Society has long told women to be small, quiet and not take up space. But when a woman steps up to a barbell, she’s pushing back against these outdated rules. One woman in our study said: <blockquote> We don’t have to […] look a certain way, or […] be scared that we can lift heavier weights than some men. Why should we? </blockquote> This shift in mindset helps women see themselves differently. Instead of worrying about being objects for others to look at, they begin to see their bodies as capable and strong. Another participant explained: <blockquote> Powerlifting changed my life. It made me see myself, or my body. My body wasn’t my value, it was the vehicle that I was in to execute whatever it was that I was executing in life. </blockquote> This newfound confidence often spills over into other areas of life. As one woman said: <blockquote> I love being a strong woman. It’s like going against the grain, and it empowers me. When I’m physically strong, everything in the world seems lighter. </blockquote> <h2>Feeling inspired? Here’s how to get started</h2> 1. Take things slow Begin with bodyweight exercises like squats, lunges and push-ups to build a foundation of strength. Once you’re comfortable, add external weights, but keep them light at first. Focus on mastering <a href="https://theconversation.com/what-are-compound-exercises-and-why-are-they-good-for-you-228385">compound movements</a>, such as deadlifts, squats and overhead presses. These exercises engage multiple joints and muscle groups simultaneously, making your workouts more efficient. 2. Prioritise proper form Always prioritise proper form over lifting heavier weights. Poor technique can lead to injuries, so learning the correct way to perform each exercise is crucial. To help with this, consider working with an exercise professional who can provide personalised guidance and ensure you’re performing exercises correctly, at least initially. 3. Consistency is key Like any fitness regimen, consistency is key. Two to three sessions a week are plenty for most women to see benefits. And don’t be afraid to occupy space in the weights room – remember you belong there just as much as anyone else. 4. Find a community Finally, join a community. There’s nothing like being surrounded by a group of strong women to inspire and motivate you. Engaging with a supportive community can make your strength-training journey more enjoyable and rewarding, whether it’s an in-person class or an online forum. <h2>Are there any downsides?</h2> Gym memberships can be expensive, especially for specialist weightlifting gyms. Home equipment is an option, but quality barbells and weightlifting equipment can come with a hefty price tag. Also, for women juggling work and family responsibilities, finding time to get to the gym two to three times per week can be challenging. If you’re concerned about getting too “bulky”, it’s very difficult for <a href="https://journals.sagepub.com/doi/epub/10.1177/0031512520967610">women</a> to bulk up like male bodybuilders without pharmaceutical assistance. The main risks come from poor technique or trying to lift too much too soon – issues that can be easily avoided with some guidance.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/221307/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/erin-kelly-1497598">Erin Kelly</a>, Lecturer and PhD Candidate, Discipline of Sport and Exercise Science, <a href="https://theconversation.com/institutions/university-of-canberra-865">University of Canberra</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Larry Emdur gets tattooed live on air

Larry Emdur has stayed true to his promise and tattooed the initials of the other Gold Logie nominees on his bum, live on The Morning Show. After being nominated for the coveted award, Emdur said last Thursday that he would get the <a href="https://oversixty.com.au/entertainment/tv/larry-emdur-s-crazy-pledge-ahead-of-logies" target="_blank" rel="noopener">tattoo</a>, saying: “I’m so confident I won’t win, I’ll happily get all the nominees’ name initials tattooed on my a*** on the show (The Morning Show) on Monday.” Emdur was up against Tony Armstrong, Andy Lee, Sonia Kruger, Robert Irwin, Julia Morris, and Asher Keddie for the highly-coveted award, but beat them all out to take home the accolade. On Monday, Emdur followed through with the outrageous promise, lazing on a massage bench in the studio. “Kylie, I can’t see what’s happening!” Larry said. <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-permalink="https://www.instagram.com/reel/C-1Q0KCvfpU/?utm_source=ig_embed&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/reel/C-1Q0KCvfpU/?utm_source=ig_embed&utm_campaign=loading" target="_blank" rel="noopener">A post shared by The Morning Show On 7 (@morningshowon7)</a> </div> </blockquote> The design included the outline of a Logie, with the initials of all the other nominees in the plaque. Larry debuted the tattoo live on air after trying to keep cool during the tattoo process. During an interview on Sunrise earlier that morning, Emdur told Nat and Shirvo it was the “dumbest promise he was ever made” after his win, laughing off the challenge as he confirmed he would be going through with the ink. Reflecting on his Gold Logie speech, Larry said it was a “surreal” moment in his career. “I knew I needed to thank my work family and my family family — I knew I wanted to thank the other nominees,” Emdur said. “It was so surreal. I was standing up there just looking down at all these famous people. I was thinking it was really a moment. “I was so humbled, thrilled and honoured … you just go wow, all of TV is in this room. Everything I worked for and everything I wanted to be part of.” Image credits: The Morning Show

No, your aches and pains don’t get worse in the cold. So why do we think they do?

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/manuela-ferreira-161420">Manuela Ferreira</a>, <a href="https://theconversation.com/institutions/george-institute-for-global-health-874">George Institute for Global Health</a> and <a href="https://theconversation.com/profiles/leticia-deveza-1550633">Leticia Deveza</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> It’s cold and wet outside. As you get out of bed, you can feel it in your bones. Your right knee is flaring up again. That’ll make it harder for you to walk the dog or go to the gym. You think it must be because of the weather. It’s a common idea, but a myth. When we looked at the evidence, <a href="https://www.sciencedirect.com/science/article/pii/S0049017224000337">we found</a> no direct link between most common aches and pains and the weather. In the first study of its kind, we found no direct link between the temperature or humidity with most joint or muscle aches and pains. So why are so many of us convinced the weather’s to blame? Here’s what we think is really going on. <h2>Weather can be linked to your health</h2> The weather is often associated with the risk of new and ongoing health conditions. For example, cold temperatures <a href="https://pubmed.ncbi.nlm.nih.gov/27021573/">may worsen</a> asthma symptoms. Hot temperatures <a href="https://www.thelancet.com/journals/lanplh/article/PIIS2542-5196(22)00117-6/fulltext">increase the risk</a> of heart problems, such as arrhythmia (irregular heartbeat), cardiac arrest and coronary heart disease. Many people are also convinced the weather is linked to their aches and pains. For example, <a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/j.1479-8077.2004.00099.x?casa_token=jvpSbA4szqoAAAAA%3ATyHyGaqXmfevWyuJe6LW_3Pap3IPHC8HSMTl3RN63mFzNO0X7ozQjBb6Bi3yVFuPjqkrf-WlB-J5A1q1">two in every three</a> people with knee, hip or hand osteoarthritis <a href="https://bmcmusculoskeletdisord.biomedcentral.com/articles/10.1186/1471-2474-15-66">say</a> cold temperatures trigger their symptoms. Musculoskeletal conditions affect more than <a href="https://www.aihw.gov.au/reports/chronic-musculoskeletal-conditions/musculoskeletal-conditions-comorbidity-australia/summary">seven million Australians</a>. So we set out to find out whether weather is really the culprit behind winter flare-ups. <h2>What we did</h2> Very few studies have been specifically and appropriately designed to look for any direct link between weather changes and joint or muscle pain. And ours is the first to evaluate data from these particular studies. We looked at data from more than 15,000 people from around the world. Together, these people reported more than 28,000 episodes of pain, mostly back pain, knee or hip osteoarthritis. People with rheumatoid arthritis and gout were also included. We then compared the frequency of those pain reports between different types of weather: hot or cold, humid or dry, rainy, windy, as well as some combinations (for example, hot and humid versus cold and dry). <h2>What we found</h2> We found changes in air temperature, humidity, air pressure and rainfall do not increase the risk of knee, hip or lower back pain symptoms and are not associated with people seeking care for a new episode of arthritis. The results of this study suggest we do not experience joint or muscle pain flare-ups as a result of changes in the weather, and a cold day will not increase our risk of having knee or back pain. In order words, there is no direct link between the weather and back, knee or hip pain, nor will it give you arthritis. It is important to note, though, that very cold air temperatures (under 10°C) were rarely studied so we cannot make conclusions about worsening symptoms in more extreme changes in the weather. The only exception to our findings was for gout, an inflammatory type of arthritis that can come and go. Here, pain increased in warmer, dry conditions. Gout has a very different underlying biological mechanism to back pain or knee and hip osteoarthritis, which may explain our results. The combination of warm and dry weather may lead to increased dehydration and consequently increased concentration of uric acid in the blood, and deposition of uric acid crystals in the joint in people with gout, resulting in a flare-up. <h2>Why do people blame the weather?</h2> The weather can influence other factors and behaviours that consequently shape how we perceive and manage pain. For example, some people may change their physical activity routine during winter, choosing the couch over the gym. And we know <a href="https://pubmed.ncbi.nlm.nih.gov/28700451/">prolonged sitting</a>, for instance, is directly linked to worse back pain. Others may change their sleep routine or sleep less well when it is either too cold or too warm. Once again, a bad night’s sleep can trigger your <a href="https://link.springer.com/article/10.1007/s00586-021-06730-6">back</a> and <a href="https://www.sciencedirect.com/science/article/pii/S1063458421007020">knee</a> pain. Likewise, changes in mood, often experienced in cold weather, trigger increases in both <a href="https://link.springer.com/article/10.1007/s00586-021-06730-6">back</a> and <a href="https://www.sciencedirect.com/science/article/pii/S1063458421007020">knee</a> pain. So these changes in behaviour over winter may contribute to more aches and pains, and not the weather itself. Believing our pain will feel worse in winter (even if this is not the case) may also make us feel worse in winter. This is known as the <a href="https://link.springer.com/article/10.1186/s12891-018-1943-8">nocebo effect</a>. <h2>What to do about winter aches and pains?</h2> It’s best to focus on risk factors for pain you can control and modify, rather than ones you can’t (such as the weather). You can: <ul> <li> become more physically active. This winter, and throughout the year, aim to walk more, or talk to your health-care provider about gentle exercises you can safely do at home, with a physiotherapist, personal trainer or at the pool </li> <li> lose weight if obese or overweight, as this is linked to <a href="https://jamanetwork.com/journals/jama/article-abstract/2799405">lower levels</a> of joint pain and better physical function </li> <li> keep your body warm in winter if you feel some muscle tension in uncomfortably cold conditions. Also ensure your bedroom is nice and warm as we tend to sleep <a href="https://www.sciencedirect.com/science/article/pii/S0033350623003359">less well</a> in cold rooms </li> <li> maintain a healthy diet and <a href="https://www.thelancet.com/journals/lanrhe/article/PIIS2665-9913(23)00098-X/fulltext">avoid smoking</a> or drinking high levels of alcohol. These are among <a href="https://ard.bmj.com/content/annrheumdis/82/1/48.full.pdf">key lifestyle recommendations</a> to better manage many types of arthritis and musculoskeletal conditions. For people with back pain, for example, a healthy lifestyle is linked with <a href="https://pubmed.ncbi.nlm.nih.gov/36208321/">higher levels</a> of physical function.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/235117/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> </li> </ul> <a href="https://theconversation.com/profiles/manuela-ferreira-161420">Manuela Ferreira</a>, Professor of Musculoskeletal Health, Head of Musculoskeletal Program, <a href="https://theconversation.com/institutions/george-institute-for-global-health-874">George Institute for Global Health</a> and <a href="https://theconversation.com/profiles/leticia-deveza-1550633">Leticia Deveza</a>, Rheumatologist and Research Fellow, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

If Australia had an aviation ombudsman, passengers could get compensation for cancelled flights

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/justin-wastnage-489752">Justin Wastnage</a>, <a href="https://theconversation.com/institutions/griffith-university-828">Griffith University</a> The financial difficulties of <a href="https://www.abc.net.au/news/2024-08-02/rex-airlines-staff-notified-of-termination/104172020">Rex Airlines</a>, coming so soon after the bankruptcy of <a href="https://www.abc.net.au/news/2024-06-26/bonza-directors-accused-of-trading-while-insolvent/104022496">Bonza</a>, have brought into sharp focus one of the federal government’s key priorities for aviation: enhancing passenger rights. In each case, passengers were left with tickets for flights that did not fly. In the case of Rex, tickets were honoured by rivals Virgin Australia and Qantas, possibly trying to recapture the small toehold Rex had established in the Brisbane-Sydney-Melbourne golden triangle. The Bonza story was more complex as the fledgling airline, which collapsed in May, had sought to exploit under-serviced routes to smaller leisure-based cities including Maroochydore and Port Macquarie. In many cases, passengers were left out-of-pocket and stranded. <h2>Support for an ombudsman</h2> These failures will have emboldened the federal government’s plans to introduce stronger passenger protections and an airline ombudsman. The release of its <a href="https://www.infrastructure.gov.au/infrastructure-transport-vehicles/aviation/aviation-white-paper">policy white paper</a> is imminent. The paper covers aviation issues including competition between airports and airlines, the sector’s environmental impact and better mechanisms for consultation. After years of opposition, <a href="https://www.travelweekly.com.au/article/qantas-and-virgin-change-tune-on-aviation-ombudsman-ahead-of-white-paper-release/">Qantas and Virgin quietly fell in behind the idea in May</a>, signalling a deal is close to being announced. The ombudsman is designed to protect consumer rights in what is often monopolistic or quasi-monopolistic operating environments. With the exception of residents of southeast Queensland and the western suburbs of Melbourne, <a href="https://www.sciencedirect.com/science/article/abs/pii/S0967070X18302063">most Australians only have one airport from which to fly.</a> This, coupled with an effective airline duopoly, can lead to higher prices and poorer service for consumers, the <a href="https://www.accc.gov.au/system/files/Airline%20competition%20in%20Australia%20-%20June%202023%20report.pdf">Australian Consumer and Competition Commission (ACCC)</a> has argued. The ACCC has been calling for better passenger rights for more than a decade. But its calls grew louder after it fined Qantas <a href="https://theconversation.com/qantas-has-finally-settled-its-ghost-flights-lawsuit-for-120-million-whats-next-229368">A$120 million for selling “ghost” flights in May</a>. Passengers did receive refunds, but the process was not easy compared to many overseas jurisdictions where compensation is automatic and based on distance travelled. Australia is rare among developed countries for not having automatic compensation if a flight is cancelled or delayed. <h2>The EU model</h2> The leader in air passenger rights, as in many areas of consumer protection, is the European Union. <a href="https://eur-lex.europa.eu/eli/reg/2004/261/oj">The EU Passenger Rights regulation</a> is 20 years old and now also applies to rail and bus passengers. The regulation favours the passenger and awards compensation <a href="https://www.airhelp.com/en-int/ec-regulation-261-2004/">of up to €600 (almost A$1,000) for delays or cancellations</a>. There are clauses for when a delay is unavoidable, but generally airlines have now built the scheme into their costs of doing business. The scheme is well publicised and in 2022, about <a href="https://schengen.news/8-million-passengers-affected-by-flight-cancellations-airport-strikes-are-eligible-for-compensation-of-up-to-e600/">eight million passengers were eligible for refunds</a>. Air passenger rights in the UK continued in the EU mould after Brexit and were even strengthened. But in a 2023 review into the UK scheme, <a href="https://www.gov.uk/government/consultations/reforming-aviation-consumer-policy-protecting-air-passenger-rights/outcome/response-to-the-aviation-consumer-policy-reform-consultation#chapter-3-compensation-for-delays-and-cancellations">some airlines argued</a> “private insurance was a better option for some passengers”, particularly those with disabilities. The same reasoning led to the removal of Australia’s previous consumer protection scheme for airline passengers, the <a href="https://www.travelmanagers.com.au/peaceofmind/#:%7E:text=The%20Travel%20Compensation%20Fund%20continued,and%20until%2030%20June%202014.">Travel Compensation Fund</a>, which refunded customers when airlines or travel agencies went bankrupt. The scheme was ended under the Abbott government in June 2014, with travellers told instead to take out their own travel insurance. Labor is expected to reintroduce an element of corporate responsibility for airline delays, not least since Brazil, Canada and Türkiye have also followed the EU’s lead. Brazil’s scheme is particularly generous, with up to R7,500 (A$1,950) available to passengers who have to pay for last minute accommodation if their flight is cancelled. Lawmakers there countered claims by airlines that low cost airline passengers could stay in cheaper hotels, by applying the compensation uniformly, regardless of travel class. <h2>Popular with voters</h2> Air passenger rights can be a vote winner, too. Before he withdrew his bid for reelection, US President Joe Biden trumpeted the <a href="https://www.transportation.gov/briefing-room/biden-harris-administration-announces-final-rule-requiring-automatic-refunds-airline">automatic airline compensation scheme</a> the US Department for Transportation will bring in this year. Until now, airline compensation was mandated by the states without coordinated processes meaning some airlines used vouchers, some credits and a few cash to compensate customers. Despite this, about <a href="https://www.transportation.gov/briefing-room/biden-harris-administration-announces-final-rule-requiring-automatic-refunds-airline">US$3 billion (A$4.6 billion)</a> in refunds have been issued to US passengers since 2020, including more than US$600 million to Southwest Airlines passengers alone. This was due to a serious scheduling crisis which forced the low-cost carrier to cancel almost 60% of its flights in the 2022 summer. By contrast, in Australia, air passengers have only had basic protections under <a href="https://consumer.gov.au/australian-consumer-law/legislation">consumer rights law</a> since deregulation in 2002. There is no guarantee of a seat or even flight the consumer purchased. This has led consumer advocates including <a href="https://www.choice.com.au/consumer-advocacy/policy/policy-submissions/2023/november/aviation-green-paper">Choice</a> to support calls for an airline ombudsman and automatic delay and cancellation compensation.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/235679/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/justin-wastnage-489752">Justin Wastnage</a>, Adjunct Industry Fellow, Griffith Institute for Tourism, <a href="https://theconversation.com/institutions/griffith-university-828">Griffith University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

"Get over yourself": Sports fans call out Aussie Olympian's "privileged" rant

Aussie sports fans have seemingly turned on swimming champion Ariarne Titmus after she called out the standard of living in the Olympic village. Titmus, who took home the gold medal in the 400m freestyle, labelled the conditions for athletes in Paris "ridiculous". "Living in the Olympic village makes it hard to perform," the 23-year-old said in an interview on Sunday. "It's definitely not made for high performance, so it's about who can really keep it together in the mind." Some sports fans haven't received her comments well, with many taking to social media to accuse the athlete of whinging. "Give me a break, why is it always the Aussies that make excuses?" one person fumed. Another posted, "Get over yourself, remember how privileged you are to be there ... to complain is really petty." Others argued that all the athletes in Paris are "in the same boat" so there is no point in complaining. "Our athletes are becoming a bunch of spoiled whining Australian representatives. If you don't like your situation just leave go home and find a job!" one person said. Another wrote, "I'm not very impressed if the competitors think that blaming their accommodation for their performance ... get over yourselves, and remember how privileged you are to have the chance to be there." Australian Swimming head coach Rohan Taylor has also spoken about the conditions of the Olympic village, but said being adaptable is crucial for competitors in France to succeed. "The Olympics has always been a challenge," he said. "Every Olympics I've been a part of, every Olympic Games that you see, is a test of athletes' ability to come here, compete and perform when it matters." "It's about how you manage yourself and whatever environments are presented, whatever the beds are, whatever the food is, everybody deals with it." "The Olympics has always been this way and that's the way it is. And that's the beauty of it." Image credits: Panoramic/SIPA/Shutterstock Editorial

What happens in my brain when I get a migraine? And what medications can I use to treat it?

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/mark-slee-1343982">Mark Slee</a>, <a href="https://theconversation.com/institutions/flinders-university-972">Flinders University</a> and <a href="https://theconversation.com/profiles/anthony-khoo-1525617">Anthony Khoo</a>, <a href="https://theconversation.com/institutions/flinders-university-972">Flinders University</a> Migraine is many things, but one thing it’s not is “just a headache”. “Migraine” <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1029040/">comes from</a> the Greek word “hemicrania”, referring to the common experience of migraine being predominantly one-sided. Some people experience an “aura” preceding the headache phase – usually a visual or sensory experience that evolves over five to 60 minutes. Auras can also involve other domains such as language, smell and limb function. Migraine is a disease with a <a href="https://www.thelancet.com/journals/laneur/article/PIIS1474-4422(18)30322-3/fulltext">huge personal and societal impact</a>. Most people cannot function at their usual level during a migraine, and anticipation of the next attack can affect productivity, relationships and a person’s mental health. <h2>What’s happening in my brain?</h2> The biological basis of migraine is complex, and varies according to the phase of the migraine. Put simply: The earliest phase is called the prodrome. This is associated with activation of a part of the brain called the hypothalamus which is thought to contribute to many symptoms such as nausea, changes in appetite and blurred vision. <figure class="align-center "><img src="https://images.theconversation.com/files/608985/original/file-20240723-17-rgqc7v.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/608985/original/file-20240723-17-rgqc7v.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=485&fit=crop&dpr=1 600w, https://images.theconversation.com/files/608985/original/file-20240723-17-rgqc7v.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=485&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/608985/original/file-20240723-17-rgqc7v.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=485&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/608985/original/file-20240723-17-rgqc7v.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=610&fit=crop&dpr=1 754w, https://images.theconversation.com/files/608985/original/file-20240723-17-rgqc7v.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=610&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/608985/original/file-20240723-17-rgqc7v.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=610&fit=crop&dpr=3 2262w" alt="" /><figcaption>The hypothalamus is shown here in red. <a class="source" href="https://www.shutterstock.com/image-vector/brain-cross-section-showing-basal-ganglia-329843930">Blamb/Shutterstock</a></figcaption></figure> Next is the aura phase, when a wave of neurochemical changes occur across the surface of the brain (the cortex) at a rate of 3–4 millimetres per minute. This explains how usually a person’s aura progresses over time. People often experience sensory disturbances such as flashes of light or tingling in their face or hands. In the headache phase, the trigeminal nerve system is activated. This gives sensation to one side of the face, head and upper neck, leading to release of proteins such as CGRP (calcitonin gene-related peptide). This causes inflammation and dilation of blood vessels, which is the basis for the severe throbbing pain associated with the headache. Finally, the postdromal phase occurs after the headache resolves and commonly involves changes in mood and energy. <h2>What can you do about the acute attack?</h2> A useful way to conceive of <a href="https://www.migraine.org.au/factsheets">migraine treatment</a> is to compare putting out campfires with bushfires. Medications are much more successful when applied at the earliest opportunity (the campfire). When the attack is fully evolved (into a bushfire), medications have a much more modest effect. <iframe id="Pj1sC" class="tc-infographic-datawrapper" style="border: 0;" src="https://datawrapper.dwcdn.net/Pj1sC/" width="100%" height="400px" frameborder="0" scrolling="no"></iframe> Aspirin For people with mild migraine, non-specific anti-inflammatory medications such as high-dose aspirin, or standard dose non-steroidal medications (NSAIDS) can be very helpful. Their effectiveness is often enhanced with the use of an anti-nausea medication. Triptans For moderate to severe attacks, the mainstay of treatment is a class of medications called “<a href="https://assets.nationbuilder.com/migraineaus/pages/595/attachments/original/1678146819/Factsheet_15_2023.pdf?1678146819">triptans</a>”. These act by reducing blood vessel dilation and reducing the release of inflammatory chemicals. Triptans vary by their route of administration (tablets, wafers, injections, nasal sprays) and by their time to onset and duration of action. The choice of a triptan depends on many factors including whether nausea and vomiting is prominent (consider a dissolving wafer or an injection) or patient tolerability (consider choosing one with a slower onset and offset of action). As triptans constrict blood vessels, they should be used with caution (or not used) in patients with known heart disease or previous stroke. Gepants Some medications that block or modulate the release of CGRP, which are used for migraine prevention (which we’ll discuss in more detail below), also have evidence of benefit in treating the acute attack. This class of medication is known as the “gepants”. Gepants come in the form of injectable proteins (monoclonal antibodies, used for migraine prevention) or as oral medication (for example, rimegepant) for the acute attack when a person has not responded adequately to previous trials of several triptans or is intolerant of them. They do not cause blood vessel constriction and can be used in patients with heart disease or previous stroke. Ditans Another class of medication, the “ditans” (for example, lasmiditan) have been approved overseas for the acute treatment of migraine. Ditans work through changing a form of serotonin receptor involved in the brain chemical changes associated with the acute attack. However, neither the gepants nor the ditans are available through the Pharmaceutical Benefits Scheme (PBS) for the acute attack, so users must pay out-of-pocket, at a <a href="https://www.migraine.org.au/cgrp#:%7E:text=While%20the%20price%20of%20Nurtec,%2D%24300%20per%208%20wafers.">cost</a> of approximately A$300 for eight wafers. <h2>What about preventing migraines?</h2> The first step is to see if <a href="https://assets.nationbuilder.com/migraineaus/pages/595/attachments/original/1677043428/Factsheet_5_2023.pdf?1677043428">lifestyle changes</a> can reduce migraine frequency. This can include improving sleep habits, routine meal schedules, regular exercise, limiting caffeine intake and avoiding triggers such as stress or alcohol. Despite these efforts, many people continue to have frequent migraines that can’t be managed by acute therapies alone. The choice of when to start preventive treatment varies for each person and how inclined they are to taking regular medication. Those who suffer disabling symptoms or experience more than a few migraines a month <a href="https://www.nejm.org/doi/full/10.1056/NEJMra1915327">benefit the most</a> from starting preventives. Almost all migraine <a href="https://assets.nationbuilder.com/migraineaus/pages/595/attachments/original/1708566656/Factsheet_16_2024.pdf?1708566656">preventives</a> have existing roles in treating other medical conditions, and the physician would commonly recommend drugs that can also help manage any pre-existing conditions. First-line preventives include: <ul> <li>tablets that lower blood pressure (candesartan, metoprolol, propranolol)</li> <li>antidepressants (amitriptyline, venlafaxine)</li> <li>anticonvulsants (sodium valproate, topiramate).</li> </ul> Some people have none of these other conditions and can safely start medications for migraine prophylaxis alone. For all migraine preventives, a key principle is starting at a low dose and increasing gradually. This approach makes them more tolerable and it’s often several weeks or months until an effective dose (usually 2- to 3-times the starting dose) is reached. It is rare for noticeable benefits to be seen immediately, but with time these drugs <a href="https://pubmed.ncbi.nlm.nih.gov/26252585/">typically reduce</a> migraine frequency by 50% or more. <hr /> <iframe id="jxajY" class="tc-infographic-datawrapper" style="border: 0;" src="https://datawrapper.dwcdn.net/jxajY/" width="100%" height="400px" frameborder="0" scrolling="no"></iframe> <hr /> <h2>‘Nothing works for me!’</h2> In people who didn’t see any effect of (or couldn’t tolerate) first-line preventives, new medications have been available on the PBS since 2020. These medications <a href="https://pubmed.ncbi.nlm.nih.gov/8388188/">block</a> the action of CGRP. The most common PBS-listed <a href="https://assets.nationbuilder.com/migraineaus/pages/595/attachments/original/1708566656/Factsheet_16_2024.pdf?1708566656">anti-CGRP medications</a> are injectable proteins called monoclonal antibodies (for example, galcanezumab and fremanezumab), and are self-administered by monthly injections. These drugs have quickly become a game-changer for those with intractable migraines. The convenience of these injectables contrast with botulinum toxin injections (also <a href="https://www.migraine.org.au/botox">effective</a> and PBS-listed for chronic migraine) which must be administered by a trained specialist. Up to half of adolescents and one-third of young adults are <a href="https://deepblue.lib.umich.edu/bitstream/handle/2027.42/147205/jan13818.pdf">needle-phobic</a>. If this includes you, tablet-form CGRP antagonists for migraine prevention are hopefully not far away. Data over the past five years <a href="https://pubmed.ncbi.nlm.nih.gov/36718044/">suggest</a> anti-CGRP medications are safe, effective and at least as well tolerated as traditional preventives. Nonetheless, these are used only after a number of cheaper and more readily available <a href="https://assets.nationbuilder.com/migraineaus/pages/595/attachments/original/1677043425/Factsheet_2_2023.pdf?1677043425">first-line treatments</a> (all which have decades of safety data) have failed, and this also a criterion for their use under the PBS.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/227559/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/mark-slee-1343982">Mark Slee</a>, Associate Professor, Clinical Academic Neurologist, <a href="https://theconversation.com/institutions/flinders-university-972">Flinders University</a> and <a href="https://theconversation.com/profiles/anthony-khoo-1525617">Anthony Khoo</a>, Lecturer, <a href="https://theconversation.com/institutions/flinders-university-972">Flinders University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

You don’t need a doctor to get more physically active – here are 10 simple steps you can take by yourself

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/nerys-m-astbury-410114">Nerys M Astbury</a>, <a href="https://theconversation.com/institutions/university-of-oxford-1260">University of Oxford</a> We all know physical activity has many <a href="https://www.nhs.uk/live-well/exercise/exercise-health-benefits/">health benefits</a>, including for mental health. It helps <a href="https://theconversation.com/exercise-can-reduce-stress-and-improve-sleep-particularly-for-women-with-breast-cancer-186144">manage stress</a>, ease joint or back pain, and boost energy levels. Exercise can also improve <a href="https://theconversation.com/exercise-and-the-brain-three-ways-physical-activity-changes-its-very-structure-150203">brain function</a> and <a href="https://theconversation.com/exercise-really-can-help-you-sleep-better-at-night-heres-why-that-may-be-192427">sleep</a>, and lift mood. In contrast, inactivity or spending too much time <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6308180/">sedentary</a> is a leading factor in developing a range of diseases. The <a href="https://www.who.int/publications/i/item/9789240015128">World Health Organization</a> recommends we should do a weekly minimum of 150-300 minutes of moderate intensity physical activity, such as walking, or 75 minutes of vigorous physical activity, such as swimming, jogging or an exercise class – as well as <a href="https://theconversation.com/strength-training-could-be-the-answer-to-one-of-the-worlds-worst-killers-228665">regular strength training</a>. However, many people <a href="https://www.who.int/teams/health-promotion/physical-activity/global-status-report-on-physical-activity-2022">fail to meet these guidelines</a>. So what to do about this <a href="https://www.weforum.org/agenda/2022/12/lack-exercise-inactivity-preventable-diseases/">health crisis</a>? There is already <a href="https://www.bmj.com/content/376/bmj-2021-068465">evidence</a> that when GPs give patients guidance and continued support to increase physical activity, this encourages them to be more physically active – at least in the short term. However, we don’t yet know the best way for doctors to communicate with patients to help them sustain these increased activity levels so the current guidance and support on offer to patients isn’t as effective as it could be. <figure><iframe src="https://www.youtube.com/embed/vCCD1xHKpZc?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> For example, my <a href="https://www.bmj.com/content/386/bmj-2023-078713">latest research</a> examines the <a href="https://www.bmj.com/content/340/bmj.c1900">“motivational interviewing” (MI)</a> method GPs currently use to encourage patients to change their lifestyle. MI is a patient-centred, non-confrontational communication style that helps patients address any problem behaviour by exploring their ambivalence towards changing it. MI has been shown to help patients with a host of health problems, including <a href="https://pubmed.ncbi.nlm.nih.gov/25577724/">addiction issues</a>, <a href="https://pubmed.ncbi.nlm.nih.gov/23001832/">eating disorders</a>, <a href="https://pubmed.ncbi.nlm.nih.gov/25726920/">smokers</a> and those with <a href="https://pubmed.ncbi.nlm.nih.gov/33637368/">diabetes</a> to change their behaviour. However, I found that while MI programmes can help patients increase their total amount of physical activity – the benefits are only short term. <h2>Ten simple ways to be more physically active</h2> If you want more physical activity in your life, then, there are many self-directed things you can do to help yourself, without joining a programme or seeing your GP. Here are ten simple and effective ways to help you become – and stay – more physically active: 1) Don’t sit, stand We <a href="https://theconversation.com/sitting-is-bad-for-your-health-and-exercise-doesnt-seem-to-offset-the-harmful-effects-225056">sit a lot</a>. In fact, it’s likely you’re sitting right now – and you needn’t be. Sitting for long periods has been <a href="https://doi.org/10.1016/j.amepre.2010.05.024">linked</a> with many adverse health outcomes, so try to stand more. <figure><iframe src="https://www.youtube.com/embed/wUEl8KrMz14?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> 2) Take the stairs Being physically active needn’t mean expensive gym memberships. Try building physical activity into your daily routine. One easy way to do this is by swapping the lift or escalator for the stairs. 3) Make it fun If you like doing something, you’re <a href="https://theconversation.com/why-you-shouldnt-let-guilt-motivate-you-to-exercise-220342">more likely</a> to continue doing it. Why not try an activity you liked doing as a child, or even something new? Who knows, you might enjoy it. 4) Phone a friend Exercising <a href="https://theconversation.com/exercise-can-be-punishing-but-heres-how-to-stop-thinking-of-it-as-a-punishment-76167">with a friend</a> or loved one is a great way to stay motivated, and it can make physical activity more fun too. 5) Do less, more often <a href="https://pilotfeasibilitystudies.biomedcentral.com/articles/10.1186/s40814-023-01272-8">“Snacktivity”</a> – a term for breaking up your activity into shorter <a href="https://theconversation.com/forget-the-gym-in-january-exercise-snacking-is-the-way-forward-69702">activity “snacks”</a> – can help you increase activity in convenient, manageable bursts while reaping the health benefits. 6) Track your progress Activity trackers aren’t a fad. There is <a href="https://doi.org/10.1016/S2589-7500(22)00111-X">evidence</a> that just using an activity tracker such as a pedometer to count steps or a smart watch that logs activity can help increase your activity levels, reduce body fat and increase muscle mass – and increase your overall physical fitness. 7) Get into a habit We know it takes about ten weeks to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3505409/">form a habit</a>. Repetition is key – so stick with it and keep going. Once you’ve formed a physical activity habit, it will be <a href="https://www.psychologytoday.com/gb/basics/habit-formation#:%7E:text=Building%20healthy%20habits%20can%20involve,listening%20to%20music%20while%20exercising">hard to shake it off</a>.). 8) Hold still Try to incorporate <a href="https://en.wikipedia.org/wiki/Isometric_exercise">isometric exercises</a> like the plank or wall squats into your routine. These exercises, which need no equipment, require you to tighten muscles and hold still – and have been shown to <a href="https://bjsm.bmj.com/content/57/20/1317">lower your blood pressure</a>. 9) Set a goal Give yourself an achievable target to work towards – it will <a href="https://theconversation.com/three-tips-to-help-you-stay-motivated-to-keep-exercising-all-year-long-175868">motivate you</a> to reach your goal. 10) Reward yourself And don’t forget to reward yourself when you meet that goal. You can also build in rewards to mark your progress along the way. After all, who doesn’t like to treat themselves when they’ve done well?<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/231991/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/nerys-m-astbury-410114">Nerys M Astbury</a>, Associate professor, <a href="https://theconversation.com/institutions/university-of-oxford-1260">University of Oxford</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Cheeky diet soft drink getting you through the work day? Here’s what that may mean for your health

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/lauren-ball-14718">Lauren Ball</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> and <a href="https://theconversation.com/profiles/emily-burch-438717">Emily Burch</a>, <a href="https://theconversation.com/institutions/southern-cross-university-1160">Southern Cross University</a> Many people are <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7230225/">drinking less</a> sugary soft drink than in the past. This is a great win for public health, given the <a href="https://jamanetwork.com/journals/jamainternalmedicine/fullarticle/2749350">recognised risks</a> of diets high in sugar-sweetened drinks. But over time, intake of diet soft drinks has <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7230225/">grown</a>. In fact, it’s so high that these products are now regularly <a href="https://www.sciencedirect.com/science/article/pii/S0160412020319188">detected in wastewater</a>. So what does the research say about how your health is affected in the long term if you drink them often? <h2>What makes diet soft drinks sweet?</h2> The World Health Organization (WHO) <a href="https://www.who.int/news/item/04-03-2015-who-calls-on-countries-to-reduce-sugars-intake-among-adults-and-children">advises</a> people “reduce their daily intake of free sugars to less than 10% of their total energy intake. A further reduction to below 5% or roughly 25 grams (six teaspoons) per day would provide additional health benefits.” But most regular soft drinks contain <a href="https://www.actiononsugar.org/surveys/2014/sugar-sweetened-beverages/">a lot of sugar</a>. A regular 335 millilitre can of original Coca-Cola contains at least <a href="https://www.coca-cola.com/ng/en/about-us/faq/how-much-sugar-is-in-cocacola-original-taste">seven</a> teaspoons of added sugar. Diet soft drinks are designed to taste similar to regular soft drinks but without the sugar. Instead of sugar, diet soft drinks contain artificial or natural sweeteners. The artificial sweeteners include aspartame, saccharin and sucralose. The natural sweeteners include stevia and monk fruit extract, which come from plant sources. Many artificial sweeteners are much sweeter than sugar so less is needed to provide the same burst of sweetness. Diet soft drinks are marketed as healthier alternatives to regular soft drinks, particularly for people who want to reduce their sugar intake or manage their weight. But while surveys of Australian <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7551593/">adults</a> and <a href="https://www.cambridge.org/core/journals/public-health-nutrition/article/adolescents-knowledge-and-beliefs-regarding-health-risks-of-soda-and-diet-soda-consumption/32F3E0FD6727F18F04C63F0390595131">adolescents</a> show most people understand the benefits of reducing their sugar intake, they often aren’t as aware about how diet drinks may affect health more broadly. <h2>What does the research say about aspartame?</h2> The artificial sweeteners in soft drinks are considered safe for consumption by food authorities, including in the <a href="https://www.fda.gov/food/food-additives-petitions/aspartame-and-other-sweeteners-food">US</a> and <a href="https://www.foodstandards.gov.au/consumer/additives/aspartame">Australia</a>. However, some <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4899993/">researchers</a> have raised concern about the long-term risks of consumption. People who drink diet soft drinks regularly and often are <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4446768/">more likely</a> to develop certain metabolic conditions (such as diabetes and heart disease) than those who don’t drink diet soft drinks. The link was found even after accounting for other dietary and lifestyle factors (such as physical activity). In 2023, the WHO announced reports had found aspartame – the main sweetener used in diet soft drinks – was “<a href="https://www.who.int/news/item/14-07-2023-aspartame-hazard-and-risk-assessment-results-released">possibly carcinogenic to humans</a>” (carcinogenic means cancer-causing). Importantly though, the report noted there is not enough current scientific evidence to be truly confident aspartame may increase the risk of cancer and emphasised it’s safe to consume occasionally. <h2>Will diet soft drinks help manage weight?</h2> Despite the word “diet” in the name, diet soft drinks are not strongly linked with weight management. In 2022, the WHO conducted a <a href="https://www.who.int/news/item/15-05-2023-who-advises-not-to-use-non-sugar-sweeteners-for-weight-control-in-newly-released-guideline">systematic review</a> (where researchers look at all available evidence on a topic) on whether the use of artificial sweeteners is beneficial for weight management. Overall, the randomised controlled trials they looked at suggested slightly more weight loss in people who used artificial sweeteners. But the observational studies (where no intervention occurs and participants are monitored over time) found people who consume high amounts of artificial sweeteners tended to have an increased risk of higher body mass index and a 76% increased likelihood of having obesity. In other words, artificial sweeteners may not directly help manage weight over the long term. This resulted in the WHO <a href="https://www.who.int/news/item/15-05-2023-who-advises-not-to-use-non-sugar-sweeteners-for-weight-control-in-newly-released-guideline">advising</a> artificial sweeteners should not be used to manage weight. <a href="http://www.cell.com/cell-metabolism/fulltext/S1550-4131(16)30296-0">Studies</a> in animals have suggested consuming high levels of artificial sweeteners can signal to the brain it is being starved of fuel, which can lead to more eating. However, the evidence for this happening in humans is still unproven. <h2>What about inflammation and dental issues?</h2> There is <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10817473/">some early evidence</a> artificial sweeteners may irritate the lining of the digestive system, causing inflammation and increasing the likelihood of diarrhoea, constipation, bloating and other symptoms often associated with irritable bowel syndrome. However, this study noted more research is needed. High amounts of diet soft drinks have <a href="https://bmcpublichealth.biomedcentral.com/articles/10.1186/s12889-023-17223-0">also been</a> linked with liver disease, which is based on inflammation. The consumption of diet soft drinks is also <a href="https://link.springer.com/article/10.1007/s40368-019-00458-0#:%7E:text=Diet%20soft%20drinks%20often%20have,2006">associated</a> with dental erosion. Many soft drinks contain phosphoric and citric acid, which can damage your tooth enamel and contribute to dental erosion. <h2>Moderation is key</h2> As with many aspects of nutrition, moderation is key with diet soft drinks. Drinking diet soft drinks occasionally is unlikely to harm your health, but frequent or excessive intake may increase health risks in the longer term. Plain water, infused water, sparkling water, herbal teas or milks remain the best options for hydration.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/233438/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/lauren-ball-14718">Lauren Ball</a>, Professor of Community Health and Wellbeing, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> and <a href="https://theconversation.com/profiles/emily-burch-438717">Emily Burch</a>, Accredited Practising Dietitian and Lecturer, <a href="https://theconversation.com/institutions/southern-cross-university-1160">Southern Cross University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

"They lied": Kerri-Anne Kennerley blasts I’m A Celeb

Kerri-Anne Kennerley has opened up on her dramatic appearance on I’m A Celebrity … Get Me Out Of Here! last year, claiming that she was "lied to" ahead of her decision to sign up. Speaking to Tammin Sursok on her podcast, The Sh*t Show, Kennerly alleged that Network Ten made promises they couldn't keep. “[Ten] came to me and promised me this, this and this … and I had nothing else to do at the time,” the TV veteran claimed. “I got promised a bunch of stuff and they lied. And so instead of being in there, the three weeks I committed to, I got out in three days. They lied.” Sursok asked her to elaborate on the promises they made, but Kennerley refused. “I don’t want to go into it now. History. And I’m even dumbfounded that I said to myself after I’ve gone, oh my God. I avoided exactly what happened for 10 years. “ … If I had thought about it for one more nanosecond and the things that were said to me were not said to me, I wouldn’t have done it in a heartbeat.” Kennerley tearfully quit I'm A Celebrity last year after clashing with MAFS star Domenica Calarco, who she claimed called her "the most self-centred b***h” she’d ever met during an eating challenge. The TV veteran added that going on the show was the "dumbest" decision she has ever made. “Comes out as absolutely number one dumb and as backed by several of my friends – especially straight after [I left IAC], them going, ‘You didn’t tell us, we would’ve locked you in a room if you had said you were going’,” she admitted. “But I don’t know … I’ve always thought I was pretty bulletproof, and then you get wounded and move on. But no … dumb, dumb, dumb – and lies. That’s what I put it down to.” Images: Ten
