The dos and don’ts of caring for your hearing aids

<p>Proper care and maintenance of your hearing aids is important. It will ensure you to get the most out of your aids, prevent problems and maintain optimum hearing conditions. Here are some guidelines to help you care for them.</p> <p><strong>DO</strong>: clean your hearing aids regularly with a dry cloth or tissue.</p> <p><strong>DON’T</strong>: get your hearing aids wet. That means no wearing them in the shower or when swimming. If they happen to get wet, dry it off immediately.</p> <p><strong>DO</strong>: put your hearing aids in their case when you’re not using them</p> <p><strong>DON’T</strong>: wear your aids when using aftershave, hairspray, perfume, sunscreen, insect repellent and so on. They contain chemicals that could damage it. Allow time for drying before putting back on hearing aids.</p> <p><strong>DO</strong>: use a moisture protection kit/anti-humidity kit. They help with moisture problems (which can affect performance of hearing aids) and extend life of hearing aids.</p> <p><strong>DO</strong>: keep out of reach of pets and visiting grandkids. Dogs have been known to chew them up and if swallowed by either pet or grandkid, can be very dangerous.</p> <p><strong>DON’T</strong>: expose your device to extreme heats. Don’t leave them in a parked car, near a heater or wear while using a hairdryer. </p> <p><strong>DO</strong>: Store your hearing aid in a safe place that's dry and cool.</p> <p><strong>DON’T</strong>: leave your hearing aids switched on when you’re not using them.</p> <p><strong>DO</strong>: change batteries often so you won’t be stuck with aids that have suddenly run out of power.</p> <p><strong>DON’T</strong>: ever insert anything into the sound outlet as it could damage the receiver. If you can’t clean it properly, ask your hearing professional.</p> <p><strong>DO</strong>: remove any earwax that gets into your hearing aid. It could cause permanent damage.</p> <p><em>Image credits: Getty Images </em></p>

Do optimists really live longer? Here’s what the research says

<p><em><a href="https://theconversation.com/profiles/fuschia-sirois-331254">Fuschia Sirois</a>, <a href="https://theconversation.com/institutions/durham-university-867">Durham University</a></em></p> <p>Do you tend to see the glass as half full, rather than half empty? Are you always looking on the bright side of life? If so, you may be surprised to learn that this tendency could actually be good for your health.</p> <p>A <a href="https://content.apa.org/record/2020-71981-001">number of studies</a> have shown that optimists enjoy higher levels of wellbeing, better sleep, lower stress and even better cardiovascular health and immune function. And now, <a href="https://pubmed.ncbi.nlm.nih.gov/35674052/">a recent study</a> has shown that being an optimist is linked to longer life.</p> <p>To conduct their study, researchers tracked the lifespan of nearly 160,000 women aged between 50 to 79 for a period of 26 years. At the beginning of the study, the women completed a <a href="https://local.psy.miami.edu/people/faculty/ccarver/availbale-self-report-instruments/lot-r/">self-report measure of optimism</a>. Women with the highest scores on the measure were categorised as optimists. Those with the lowest scores were considered pessimists.</p> <p>Then, in 2019, the researchers followed up with the participants who were still living. They also looked at the lifespan of participants who had died. What they found was that those who had the highest levels of optimism were more likely to live longer. More importantly, the optimists were also more likely than those who were pessimists to live into their nineties. Researchers refer to this as “exceptional longevity”, considering the average lifespan for women is about 83 years in developed countries.</p> <p>What makes these findings especially impressive is that the results remained even after accounting for other factors known to predict a long life – including education level and economic status, ethnicity, and whether a person suffered from depression or other chronic health conditions.</p> <p>But given this study only looked at women, it’s uncertain whether the same would be true for men. However, <a href="https://www.pnas.org/doi/abs/10.1073/pnas.1900712116">another study</a> which looked at both men and women also found that people with the highest levels of optimism enjoyed a lifespan that was between 11% and 15% longer than those who were the least optimistic.</p> <h2>The fountain of youth?</h2> <p>So why is it that optimists live longer? At first glance it would seem that it may have to do with their healthier lifestyle.</p> <p>For example, <a href="https://www.ahajournals.org/doi/10.1161/CIRCRESAHA.117.310828">research from several studies</a> has found that optimism is linked to eating a healthy diet, staying physically active, and being less likely to smoke cigarettes. These healthy behaviours are well known to improve heart health and <a href="https://www.who.int/news-room/fact-sheets/detail/noncommunicable-diseases">reduce the risk</a> for cardiovascular disease, which is a <a href="https://www.who.int/news-room/fact-sheets/detail/cardiovascular-diseases-(cvds)">leading cause of death</a> globally. Adopting a healthy lifestyle is also <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3857242/">important for reducing the risk</a> of other potentially deadly diseases, such as diabetes and cancer.</p> <p>But having a healthy lifestyle may only be part of the reason optimists live a longer than average life. This latest study found that lifestyle only accounted for 24% of the link between optimism and longevity. This suggests a number of other factors affect longevity for optimists.</p> <p>Another possible reason could be due to the way optimists manage stress. When faced with a stressful situation, optimists tend to deal with it head-on. They <a href="https://pubmed.ncbi.nlm.nih.gov/16859439/">use adaptive coping strategies</a> that help them resolve the source of the stress, or view the situation in a less stressful way. For example, optimists will problem-solve and plan ways to deal with the stressor, call on others for support, or try to find a “silver lining” in the stressful situation.</p> <p>All of these approaches are well-known to reduce feelings of stress, as well as the biological reactions that occur when we feel stressed. It’s these <a href="https://www.apa.org/topics/stress/body">biological reactions to stress</a> –- such as elevated cortisol (sometimes called the “stress hormone”), increased heart rate and blood pressure, and impaired immune system functioning –- that can take a toll on health over time and increase the risk for developing <a href="https://www.sciencedirect.com/science/article/pii/S0889159115004316?via%3Dihub">life-threatening diseases</a>, such as cardiovascular disease. In short, the way optimists cope with stress may help protect them somewhat against its harmful effects.</p> <h2>Looking on the bright side</h2> <p>Optimism is typically viewed by researchers as a relatively stable personality trait that is determined by both <a href="https://www.cambridge.org/core/journals/twin-research-and-human-genetics/article/sex-differences-in-the-genetic-architecture-of-optimism-and-health-and-their-interrelation-a-study-of-australian-and-swedish-twins/58F21AA11943D44B4BA4C63A966E6AC7">genetic</a> and early childhood influences (such as having a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6541423/">secure and warm relationship</a> with your parents or caregivers). But if you’re not naturally prone to seeing the glass as half full, there are some ways you can increase your <a href="https://www.tandfonline.com/doi/abs/10.1080/17439760.2016.1221122?journalCode=rpos20">capacity to be optimistic</a>.</p> <p>Research shows optimism can change over time, and can be cultivated by engaging in simple exercises. For example, visualising and then writing about your “<a href="https://www.psychologytoday.com/us/blog/what-matters-most/201303/what-is-your-best-possible-self">best possible self</a>” (a future version of yourself who has accomplished your goals) is a technique that studies have found can <a href="https://www.tandfonline.com/doi/full/10.1080/17439760.2016.1221122">significantly increase optimism</a>, at least temporarily. But for best results, the goals need to be both positive and reasonable, rather than just wishful thinking. Similarly, simply <a href="https://www.tandfonline.com/doi/abs/10.3200/SOCP.149.3.349-364">thinking about positive future events</a> can also be effective for boosting optimism.</p> <p>It’s also crucial to temper any expectations for success with an accurate view of what you can and can’t control. Optimism is reinforced when we experience the positive outcomes that we expect, and <a href="https://psycnet.apa.org/record/1970-20680-001">can decrease</a> when these outcomes aren’t as we want them to be. Although more research is needed, it’s possible that regularly envisioning yourself as having the best possible outcomes, and taking realistic steps towards achieving them, can help develop an optimistic mindset.</p> <p>Of course, this might be easier said than done for some. If you’re someone who isn’t naturally optimistic, the best chances to improve your longevity is by <a href="https://journals.plos.org/plosmedicine/article?id=10.1371/journal.pmed.1003332">living a healthy lifestyle</a> by staying physically active, eating a healthy diet, managing stress, and getting a good night’s sleep. Add to this cultivating a more optimistic mindset and you might further increase your chances for a long life.<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/184785/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/fuschia-sirois-331254">Fuschia Sirois</a>, Professor in Social &amp; Health Psychology, <a href="https://theconversation.com/institutions/durham-university-867">Durham University</a></em></p> <p><em>Image credits: Shutterstock</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Do parolees really ‘walk free’? Busting common myths about parole

Here’s what the evidence says about three of the most common misconceptions.</p> <h2>Myth 1: people on parole walk free</h2> <p>Parole is the conditional release of an incarcerated person (parolee) by a parole board authority, after they have served their non-parole period (minimum sentence) in jail. This isn’t always reflected in headlines.</p> <p><a href="https://www.9news.com.au/national/snowtown-murders-bodies-in-barrels-murders-mark-haydon-release-south-australia/f4b62a72-ec3d-4238-94d2-64697fbcdef3">Some coverage</a> suggests people on parole are released early and “walk free” without conditions. This is not true.</p> <p>According to the <a href="https://www.adultparoleboard.vic.gov.au/what-parole/purpose-and-benefits">Adult Parole Board of Victoria</a>: "Parole provides incarcerated people with a structured, supported and supervised transition so that they can adjust from prison back into the community, rather than returning straight to the community at the end of their sentence without supervision or support."</p> <p>Parole comes with strict conditions and requirements, such as curfews, drug and alcohol testing, electronic monitoring, program participation, to name a few.</p> <p>People with experience of parole highlight its punitivism and continued extension of surveillance.</p> <h2>Myth 2: most parolees reoffend</h2> <p>Another myth is that the likelihood all parolees reoffend is high. Research over a number of years has consistently found parole reduces reoffending.</p> <p>For example, <a href="https://journals.sagepub.com/doi/abs/10.1177/0004865815585393?journalCode=anja">a 2016 study in New South Wales</a> found at the 12 month mark, a group of parolees reoffended 22% less than an unsupervised cohort.</p> <p>A <a href="https://www.bocsar.nsw.gov.au/Publications/CJB/2022-Report-Effect-of-parole-supervision-on-recidivism-CJB245.pdf">2022 study</a> by the NSW Bureau of Crime Statistics and Research found parole was especially successful in reducing serious recidivism rates among incarcerated people considered to be at a high risk of reoffending.</p> <p>More recently in Victoria, <a href="https://www.adultparoleboard.vic.gov.au/system/files/inline-files/Adult%20Parole%20Board%20Annual%20Report%202022-23_0.pdf">the Adult Parole Board</a> found over 2022–23, no parolees were convicted of committing serious offences while on parole.</p> <p>In contrast, unstructured and unconditional release increases the risk of returning to prison.</p> <h2>Myth 3: parole is easy to get</h2> <p>While the number of parolees reoffending has dropped, so too has the total number of people who are exiting prison on parole.</p> <p>Over a decade ago, Victoria underwent significant parole reforms, largely prompted by high-profile incidents and campaigns. In just five years following Jill Meagher’s tragic death in 2012, the Victorian government passed <a href="https://www.tandfonline.com/doi/full/10.1080/10345329.2018.1556285">13 laws reshaping parole</a>.</p> <p>The result is the number of people on parole in Victoria has halved since 2012, despite incarceration numbers remaining steady.</p> <p><iframe id="maNRy" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/maNRy/" width="100%" height="400px" frameborder="0"></iframe></p> <p>These reforms have made it more difficult for people convicted of serious offences to get parole, as well as preventing individuals or specific groups from being eligible for parole (such as police killers, <a href="https://theconversation.com/no-body-no-parole-laws-could-be-disastrous-for-the-wrongfully-convicted-191083">“no body, no parole” prisoners</a>, and certain high-profile murderers).</p> <p>Similar laws can be found in other states. For example, no body, no parole was introduced in all other Australian states and territories, except for Tasmania and the Australian Capital Territory.</p> <p>As a consequence, more people are being released at the end of their full sentence. This can be detrimental not only for the incarcerated person but the wider community, because they are not receiving the reintegration support parole provides.</p> <p>Aside from restricted access due to political intervention, parole is facing a new crisis, which has nothing to do with eligibility or suitability.</p> <p>Last year, 40% of Victorian parole applications were denied, often due to reasons <a href="https://www.adultparoleboard.vic.gov.au/system/files/inline-files/Adult%20Parole%20Board%20Annual%20Report%202022-23_0.pdf">unrelated to suitability</a>.</p> <p>Housing scarcity played a significant role, with 59% of rejections (or 235 applications) citing a lack of suitable accommodation as one of the reasons parole was denied. This is playing out <a href="https://www.abc.net.au/news/2023-08-11/women-on-bail-parole-increased-risk-of-homelessness-qld/102717002">across the country</a>.</p> <p>Parole is vulnerable to community and media hype, and political knee-jerk reactions in response to high profile incidents involving a person on parole. Because of the actions of a few, parole as a process has been restricted for many.</p> <p>While the wider community are active in advocacy efforts to restrict parole from certain people or groups (for example, this petition for <a href="https://www.change.org/p/lyns-law-no-body-no-parole">Lyn’s Law in NSW</a>), public efforts to restrict parole seem at odds with its purposes.</p> <p>Despite this, research suggests when the public are educated about the purposes and intent of parole, they are more likely to be <a href="https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3125829">supportive of it</a>.</p> <p>The susceptibility of parole to media and community influence results in frequent, impactful changes affecting individuals inside and outside prisons. Headlines such as “walking free” have the potential to mislead the public on the purpose and structure of parole. Coverage should portray parole beyond mere early termination of a sentence by accurately reflecting its purpose and impact.<!-- Below is The Conversation's page counter tag.

There are new flu vaccines on offer for 2024. Should I get one? What do I need to know?

<p><em><a href="https://theconversation.com/profiles/allen-cheng-94997">Allen Cheng</a>, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a></em></p> <p>Influenza is a common respiratory infection. Although most cases are relatively mild, flu can cause more severe illness in young children and older people.</p> <p>Influenza virtually <a href="https://pubmed.ncbi.nlm.nih.gov/33243355/">disappeared</a> from Australia during the first years of the COVID-19 pandemic when public health restrictions reduced contact between people. Since 2022, it has returned to a seasonal pattern, although the flu season has started and peaked a few months earlier than before 2020.</p> <p>It’s difficult to predict the intensity of the flu season at this point in the year, but we can sometimes get clues from the northern hemisphere. There, the season <a href="https://www.who.int/tools/flunet">started</a> <a href="https://gis.cdc.gov/grasp/fluview/flu_by_age_virus.html">earlier</a> than usual for the third year running (peaking in early January rather than late February/March), with a similar number of reported cases and hospitalisations to the previous year.</p> <p>Influenza vaccines are recommended annually, but there are now an increasing number of different vaccine types. Here’s what to know about this year’s shots, available from <a href="https://www.health.gov.au/topics/immunisation/vaccines/influenza-flu-vaccine">this month</a>.</p> <h2>What goes into a flu vaccine?</h2> <p>Like other vaccines, influenza vaccines work by “training” the immune system on a harmless component of the influenza virus (known as an antigen), so it can respond appropriately when the body encounters the real virus.</p> <p>Influenza strains are constantly changing due to genetic mutation, with the pace of genetic change <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10421855">much higher</a> than for SARS-CoV-2 (the virus that causes COVID). The strains that go into the vaccine are <a href="https://www.who.int/teams/global-influenza-programme/vaccines/who-recommendations">reviewed</a> twice each year by the World Health Organization (WHO), which selects vaccine strains to match the next season’s predicted circulating strains.</p> <p>All current influenza vaccines in <a href="https://www.tga.gov.au/resources/publication/meeting-statements/aivc-recommendations-composition-influenza-vaccines-australia-2024">Australia</a> contain four different strains (known as quadrivalent vaccines). One of the strains appeared to <a href="https://www.nejm.org/doi/full/10.1056/NEJMp2314801">disappear</a> during the COVID pandemic, and the WHO has recently <a href="https://cdn.who.int/media/docs/default-source/influenza/who-influenza-recommendations/vcm-southern-hemisphere-recommendation-2024/202309_qanda_recommendation.pdf?sfvrsn=7a6906d1_5">recommended</a> dropping this strain from the vaccine. It’s expected trivalent (three strain) vaccines will become available in the near future.</p> <h2>What’s different about new flu vaccines?</h2> <p>There are eight brands of flu vaccines <a href="https://www.health.gov.au/resources/publications/atagi-statement-on-the-administration-of-seasonal-influenza-vaccines-in-2024?language=en">available</a> in Australia in 2024. These include egg-based vaccines (Vaxigrip Tetra, Fluarix Tetra, Afluria Quad, FluQuadri and Influvac Tetra), cell-based vaccines (Flucelvax Quad), adjuvanted vaccines (Fluad Quad) and high-dose vaccines (Fluzone High-Dose Quad).</p> <p>Until recently, the process of manufacturing flu vaccines has remained similar. Since the development of the influenza vaccine in the <a href="https://www.who.int/news-room/spotlight/history-of-vaccination/history-of-influenza-vaccination">1940s</a>, influenza viruses were grown in chicken eggs, then extracted, inactivated, purified and processed to make up the egg-based vaccines that are still used widely.</p> <p>However, there have been several enhancements to influenza vaccines in recent years.</p> <p>Older people’s immune systems tend not to respond as strongly to vaccines. In some flu vaccines, adjuvants (components that stimulate the immune system) are included with the influenza antigens. For example, an adjuvant is used in the Fluad Quad vaccine, recommended for over 65s. Studies <a href="https://ncirs.org.au/sites/default/files/2021-02/Adjuvanted%20influenza%20vaccine%20vs%20standard%20dose%20influenza%20vaccine%20SoF%20EP%20E2D%20tables_26%20Feb%202021_Final.pdf">suggest</a> adjuvanted influenza vaccines are slightly better than standard egg-based vaccines without adjuvant in older people.</p> <p>An alternative approach to improving the immune response is to use higher doses of the vaccine strains. An example is Fluzone High-Dose Quad – another option for older adults – which contains the equivalent of four doses of a standard influenza vaccine. Studies <a href="https://ncirs.org.au/sites/default/files/2022-05/HD%20vs%20sIV%20SoF%20EP%20E2D_March%202022_Final.pdf">suggest</a> the high dose vaccine is better than the standard dose vaccine (without an adjuvant) in preventing hospitalisation and complications in older people.</p> <p>Other manufacturers have updated the manufacturing process. Cell-based vaccines, such as Flucelvax Quad, use cells instead of eggs in the manufacturing process. Other vaccines that are <a href="https://www.cdc.gov/flu/prevent/advances.htm">not yet available</a> also use different technologies. In the past, <a href="https://pubmed.ncbi.nlm.nih.gov/31151913/">manufacturing issues</a> with egg-based vaccines have reduced their effectiveness. Using an alternative method of production provides some degree of insurance against this in the future.</p> <h2>What should I do this year?</h2> <p>Given indications this year’s flu season may be earlier than usual, it’s probably safest to get your vaccine early. This is particularly <a href="https://www.health.gov.au/resources/publications/atagi-statement-on-the-administration-of-seasonal-influenza-vaccines-in-2024?language=en">important</a> for those at highest risk of severe illness, including older adults (65 years and over), those with chronic medical conditions, young children (six months to five years) and Aboriginal and Torres Strait Islander people. Influenza vaccines are also recommended in pregnancy to protect both the mother and the baby for the first months of life.</p> <p>Influenza vaccines are widely available, including at GP clinics and pharmacies, while many workplaces have occupational programs. For high-risk groups, <a href="https://www.health.gov.au/topics/immunisation/vaccines/influenza-flu-vaccine">four of the vaccines</a> are subsidised by the Australian government through the <a href="https://www.health.gov.au/our-work/national-immunisation-program">National Immunisation Program</a>.</p> <p>In older people, a number of vaccines are now recommended: <a href="https://www.health.gov.au/sites/default/files/2024-03/atagi-statement-on-the-administration-of-covid-19-vaccines-in-2024.pdf">COVID</a> and influenza, as well as one-off courses of <a href="https://www.health.gov.au/sites/default/files/documents/2020/06/national-immunisation-program-pneumococcal-vaccination-schedule-from-1-july-2020-clinical-advice-for-vaccination-providers.pdf">pneumococcal</a> and <a href="https://www.health.gov.au/topics/immunisation/vaccines/shingles-herpes-zoster-immunisation-service">shingles</a> vaccines. In general, most vaccines can be given in the same visit, but talk to your doctor about which ones you need.</p> <h2>Are there side effects?</h2> <p>All influenza vaccines can <a href="https://www.health.gov.au/topics/immunisation/vaccines/influenza-flu-vaccine">cause</a> a sore arm and sometimes more generalised symptoms such as fever and tiredness. These are expected and reflect the immune system reacting appropriately to the vaccine, and are mostly mild and short-term. These side effects are slightly more common in <a href="https://ncirs.org.au/sites/default/files/2021-02/Adjuvanted%20influenza%20vaccine%20vs%20standard%20dose%20influenza%20vaccine%20SoF%20EP%20E2D%20tables_26%20Feb%202021_Final.pdf">adjuvanted</a> and <a href="https://ncirs.org.au/sites/default/files/2022-05/HD%20vs%20sIV%20SoF%20EP%20E2D_March%202022_Final.pdf">high dose</a> vaccines.</p> <p>As with all medications and vaccines, allergic reactions such as anaphylaxis can occur after the flu vaccine. All vaccine providers are trained to recognise and respond to anaphylaxis. People with egg allergies should discuss this with their doctor, but in general, <a href="https://www.allergy.org.au/patients/food-allergy/egg-allergy-flu-vaccine">studies suggest</a> they can safely receive any (including egg-based) influenza vaccines.</p> <p>Serious side effects from the influenza vaccine, such as Guillain-Barré syndrome, a neurological complication, are very rare (one case per million people vaccinated). They are <a href="https://pubmed.ncbi.nlm.nih.gov/23810252/">thought</a> to be less common after influenza vaccination than after infection with influenza.<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/226623/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/allen-cheng-94997">Allen Cheng</a>, Professor of Infectious Diseases, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a></em></p> <p><em>Image credits: Shutterstock</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Why do airlines charge so much for checked bags? This obscure rule helps explain why

<p><em><a href="https://theconversation.com/profiles/jay-l-zagorsky-152952">Jay L. Zagorsky</a>, <a href="https://theconversation.com/institutions/boston-university-898">Boston University</a></em></p> <p>Five out of the six <a href="https://www.oag.com/blog/biggest-airlines-in-the-us">biggest U.S. airlines</a> have <a href="https://www.cnbc.com/2024/03/05/delta-is-the-latest-airline-to-raise-its-checked-bag-fee.html">raised their checked bag fees</a> since January 2024.</p> <p>Take American Airlines. In 2023, it cost US$30 to check a standard bag in with the airline; <a href="https://www.usatoday.com/story/travel/airline-news/2024/02/20/american-airlines-bag-fees-mileage-earning/72669245007/">today, as of March 2024, it costs $40</a> at a U.S. airport – a whopping 33% increase.</p> <p>As a <a href="https://www.bu.edu/questrom/">business school</a> <a href="https://www.bu.edu/questrom/profile/jay-zagorsky/">professor who studies travel</a>, I’m often asked why airlines alienate their customers with baggage fees instead of bundling all charges together. <a href="https://www.vox.com/2015/4/16/8431465/airlines-carry-on-bags">There are</a> <a href="https://www.usatoday.com/story/travel/columnist/2023/06/21/bag-fees-will-stay-a-while-cruising-altitude/70338849007/">many reasons</a>, but an important, often overlooked cause is buried in the U.S. tax code.</p> <h2>A tax-law loophole</h2> <p>Airlines pay the federal government <a href="https://www.ecfr.gov/current/title-26/chapter-I/subchapter-D/part-49/subpart-D">7.5% of the ticket price</a> when <a href="https://www.pwc.com/us/en/services/tax/library/aircraft-club-nov-2023-air-transport-excise-tax-rates-for-2024.html">flying people domestically, alongside other fees</a>. The airlines dislike these charges, with their <a href="https://www.airlines.org/dataset/government-imposed-taxes-on-air-transportation/">trade association arguing</a> that they boost the cost to the consumer of a typical air ticket by around one-fifth.</p> <p>However, the U.S. Code of Federal Regulations <a href="https://www.ecfr.gov/current/title-26/chapter-I/subchapter-D/part-49/subpart-D/section-49.4261-8">specifically excludes baggage</a> from the 7.5% transportation tax as long as “the charge is separable from the payment for the transportation of a person and is shown in the exact amount.”</p> <p>This means if an airline charges a combined $300 to fly you and a bag round-trip within the U.S., it owes $22.50 in tax. If the airline charges $220 to fly you plus separately charges $40 each way for the bag, then your total cost is the same — but the airline only owes the government $16.50 in taxes. Splitting out baggage charges saves the airline $6.</p> <p>Now $6 might not seem like much, but it can add up. Last year, passengers took <a href="https://www.transtats.bts.gov/Data_Elements.aspx?Data=1">more than 800 million trips on major airlines</a>. Even if only a fraction of them check their bags, that means large savings for the industry.</p> <p>How large? The government has <a href="https://www.bts.dot.gov/topics/airlines-and-airports/baggage-fees-airline-2023">tracked revenue from bag fees</a> for decades. In 2002, airlines charged passengers a total of $180 million to check bags, which worked out to around 33 cents per passenger.</p> <p>Today, as any flyer can attest, bag fees are a lot higher. Airlines collected over 40 times more money in bag fees last year than they did in 2002.</p> <p>When the full data is in for 2023, <a href="https://www.bts.dot.gov/baggage-fees">total bag fees</a> will likely top $7 billion, which is about $9 for the average domestic passenger. <a href="https://viewfromthewing.com/the-real-reason-airlines-charge-checked-bag-fees-and-its-not-what-you-think">By splitting out the cost of bags</a>, airlines avoided paying about half a billion dollars in taxes just last year.</p> <p>In the two decades since 2002, flyers paid a total of about $70 billion in bag fees. This means separately charging for bags saved airlines about $5 billion in taxes.</p> <p><iframe id="88MYD" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/88MYD/2/" width="100%" height="400px" frameborder="0"></iframe></p> <p>It seems clear to me that tax savings are one driver of the unbundling of baggage fees because of a quirk in the law.</p> <p>The U.S. government doesn’t apply the 7.5% tax to <a href="https://www.ecfr.gov/current/title-26/chapter-I/subchapter-D/part-49/subpart-D/section-49.4261-3">international flights that go more than 225 miles</a> beyond the nation’s borders. Instead, there are fixed <a href="https://www.airlines.org/dataset/government-imposed-taxes-on-air-transportation">international departure and arrival taxes</a>. This is why major airlines charge $35 to $40 <a href="https://www.aa.com/i18n/travel-info/baggage/checked-baggage-policy.jsp">for bags if you’re flying domestically</a>, but don’t charge a bag fee when you’re flying to Europe or Asia.</p> <h2>Do travelers get anything for that money?</h2> <p>This system raises an interesting question: Do baggage fees force airlines to be more careful with bags, since customers who pay more expect better service? To find out, I checked with the Bureau of Transportation Statistics, which has been <a href="https://www.bts.gov/content/mishandled-baggage-reports-filed-passengers-largest-us-air-carriersa">tracking lost luggage for decades</a>.</p> <p>For many years, it calculated the number of mishandled-baggage reports per thousand airline passengers. The government’s data showed mishandled bags peaked in 2007 with about seven reports of lost or damaged luggage for every thousand passengers. That means you could expect your luggage to go on a different trip than the one you are taking about once every 140 or so flights. By 2018, that estimate had fallen to once every 350 flights.</p> <p>In 2019, the government <a href="https://www.bts.gov/topics/airlines-and-airports/number-30a-technical-directive-mishandled-baggage-amended-effective-jan">changed how it tracks</a> mishandled bags, calculating figures based on the total number of bags checked, rather than the total number of passengers. The new data show about six bags per thousand checked get lost or damaged, which is less than 1% of checked bags. Unfortunately, the data doesn’t show improvement since 2019.</p> <p>Is there anything that you can do about higher bag fees? Complaining to politicians probably won’t help. In 2010, two senators <a href="https://www.nj.com/business/2010/04/us_senators_present_bill_to_ba.html">tried to ban bag fees</a>, and their bill went nowhere.</p> <p>Given that congressional action failed, there’s a simple way to avoid higher bag fees: <a href="https://www.cnn.com/travel/article/packing-expert-travel-world-handbag/index.html">travel light</a> and <a href="https://www.nytimes.com/2023/07/08/opinion/carry-on-packing-airlines-lost-luggage.html">don’t check any luggage</a>. It may sound tough not to have all your belongings when traveling, but it might be the best option as bag fees take off.<!-- Below is The Conversation's page counter tag.

6 major benefits of doing yoga every day, from experts

<h2>Positive effects of yoga</h2> <p style="font-size: medium; font-weight: 400;">Sometimes it’s the simplest daily practice that can have the biggest impact on your health, and yoga is proof of that. Although most forms of yoga aren’t considered to be as intense as other workout regimens (think your average cycling class!), practising yoga on a daily basis has been scientifically demonstrated to help you mentally and physically. Through breath work, meditation and holding poses that increase strength and flexibility, the body and mind reap benefits from yoga that positively impact your long-term health. It’s no wonder people have been practising yoga for over 5000 years, and that the number of Australians practising yoga doubled between 2008 and 2017 to over two million, according to the Australian Bureau of Statistics.</p> <p style="font-size: medium; font-weight: 400;">In order to get the full scope of what practising yoga daily can really do for your body, we spoke with several experts who have seen the ways yoga has positively benefited their students, patients… and even themselves.</p> <p style="font-size: medium; font-weight: 400;"><a href="https://gaiam.innovations.co.nz/p/gaiam-yoga/mats?affiliate=GAIAM60" target="_blank" rel="noopener">Keen to try? You’ll need a mat. There’s a range of mats to suit every yoga level, check out these we recommend.</a></p> <h2>Yoga assists with mood regulation</h2> <p style="font-size: medium; font-weight: 400;"><img src="https://oversixtydev.blob.core.windows.net/media/2024/03/6benefitsyoga_getty2.jpg" alt="" width="1280" height="720" /></p> <p style="font-size: medium; font-weight: 400;">Yoga teacher, Jenni Tarma, shares, “We have a wealth of research demonstrating that a regular mindfulness practice – the act of paying attention to the sensation in the body, thoughts and emotions without judgment – can reduce stress and help us to feel calmer, more productive, and generally more even-keeled in our daily lives.”</p> <p style="font-size: medium; font-weight: 400;">After evaluating yoga history and research, one 2014 review published in Frontiers in Human Neouroscience concluded that regular yoga practice can help facilitate self-regulation (the ability to understand and manage your behaviour and reactions). Another study of adolescents between the ages of 13 and 18 found that practising yoga positively benefited emotional regulation and self-esteem. “Movement releases beneficial neurotransmitters in the brain, which helps us feel good as well as assist in mood regulation,” says yoga instructor, Evan Lawrence. “One of the things that I like about yoga specifically is that there is simultaneously a focus on physical movement and breathing.”</p> <p style="font-size: medium; font-weight: 400;"><a href="https://www.readersdigest.co.nz/culture/23-instant-mood-boosters-you-wont-want-to-live-without" target="_blank" rel="noopener">Don’t miss these instant mood boosters you won’t want to live without.</a></p> <h2>Yoga builds up your core strength</h2> <p style="font-size: medium; font-weight: 400;"><img src="https://oversixtydev.blob.core.windows.net/media/2024/03/6benefitsyoga_shutterstock3.jpg" alt="" width="1280" height="720" /></p> <p style="font-size: medium; font-weight: 400;">Personal trainer and yoga teacher, Gina Newton, says, “From a physical perspective, yoga is so great for increasing our core strength, which should be a non-negotiable part of every human’s workout.” Newton adds, “We all need our core – and especially women who have been pregnant or had children, our core strength is something we need to care for and nurture to hold us up.”</p> <p style="font-size: medium; font-weight: 400;">According to Harvard Medical School, a stronger core benefits the body in multiple ways, including providing better posture, balance, stability, relief for lower back pain, and support through daily tasks like cleaning, working, and athletic activities or exercise.</p> <p style="font-size: medium; font-weight: 400;">Wearing comfortable yoga gear will help you get the most out of your workout. <a href="https://gaiam.innovations.co.nz/p/gaiam-apparel/apparel?affiliate=GAIAM60" target="_blank" rel="noopener">Check out these yoga clothes from Gaiam.</a></p> <h2>Yoga reduces stress</h2> <p style="font-size: medium; font-weight: 400;"><img src="https://oversixtydev.blob.core.windows.net/media/2024/03/6benefitsyoga_getty4.jpg" alt="" width="1280" height="720" /></p> <p style="font-size: medium; font-weight: 400;">“Yoga and meditation are powerful tools for stress resilience and strengthening mental health,” says holistic healthcare practitioner and yoga instructor, Nicole Renée Matthews.  “Doing yoga regularly promotes mental clarity and calmness, centres and relaxes the mind, helps to relieve stress patterns and anxiety, and boosts concentration and focus.”</p> <p style="font-size: medium; font-weight: 400;">One 2010 study from the Journal of Alternative and Complementary Medicine concluded that practising yoga can improve mood and decrease anxiety even more than a regular walking practice after participants finished a 12-week program. Researchers have also found that the breath-taking techniques involved with yoga can be part of what benefits decreased anxiety during practice.</p> <p style="font-size: medium; font-weight: 400;">“Breath awareness, another key component of yoga, has been shown to reduce physiological markers of stress, especially when using techniques such as ‘belly breathing’ – breathing deeply so that the abdomen expands, rather than exclusively using a shallow chest breath – and elongating the exhalation,” says Tarma. “These techniques help to activate the parasympathetic nervous system, which in turn leads to less anxiety, jitteriness, and improved sleep; all things that can improve our mental health on a day-to-day basis.”</p> <p style="font-size: medium; font-weight: 400;"><a href="https://www.readersdigest.co.nz/healthsmart/conditions/mental-health/10-science-backed-ways-to-lower-your-stress-this-instant-really" target="_blank" rel="noopener">Don’t miss these science-backed ways to lower your stress this instant (really!).</a></p> <h2>Yoga improves brain health</h2> <p style="font-size: medium; font-weight: 400;"><img src="https://oversixtydev.blob.core.windows.net/media/2024/03/6benefitsyoga_getty5.jpg" alt="" width="1280" height="720" /></p> <p style="font-size: medium; font-weight: 400;">According to associate professor of psychiatry, Dr Gail Saltz, practising yoga “improves overall blood flow to the body, including the brain, [which is] helpful for cognition and memory.”</p> <p style="font-size: medium; font-weight: 400;">One 2019 review published in Brain Plasticity concluded that behavioural interventions like yoga can help “mitigate age-related and neurodegenerative decline” due to the positive effects a daily practice has on different parts of the functioning brain, like the hippocampus (which plays a major role in learning and memory) and the prefrontal cortex (cognitive control functions).</p> <p style="font-size: medium; font-weight: 400;">Staying hydrated is key to maintaining optimum brain health. <a href="https://gaiam.innovations.co.nz/p/takeya/water-bottles-actives-range?affiliate=GAIAM60" target="_blank" rel="noopener">These drink bottles can help you keep your water intake up throughout the day.</a></p> <h2>Yoga improves flexibility and mobility</h2> <p style="font-size: medium; font-weight: 400;"><img src="https://oversixtydev.blob.core.windows.net/media/2024/03/6benefitsyoga_shutterstock6.jpg" alt="" width="1280" height="720" /></p> <p style="font-size: medium; font-weight: 400;">“Physically, daily yoga practice allows us to engage our muscles and move through larger ranges of joint motion than we do typically moving through life,” says Lawrence. “This helps to keep us limber and flexible.”</p> <p style="font-size: medium; font-weight: 400;">“Dedicated, daily yoga practice helps with flexibility and strength, which can help improve your posture, as well as balance,” says yoga instructor, Samantha Hoff. “On the physical side, it also helps with joint mobility since you’ll take your joints through most – or all – of their ranges of motion.”</p> <p style="font-size: medium; font-weight: 400;"><a href="https://www.readersdigest.co.nz/healthsmart/12-best-yoga-poses-to-strengthen-bones" target="_blank" rel="noopener">Here are the best yoga poses to strengthen bones.</a></p> <h2>Yoga strengthens muscle and endurance</h2> <p style="font-size: medium; font-weight: 400;"><img src="https://oversixtydev.blob.core.windows.net/media/2024/03/6benefitsyoga_getty7.jpg" alt="" width="1280" height="720" /></p> <p style="font-size: medium; font-weight: 400;">“From a musculoskeletal perspective,” says Tarma, “yoga loads our bodies and joints in a wide variety of positions and scenarios: think longer static holds in poses that challenge our tissues’ endurance, or controlled transitions between shapes that develop strength, control and coordination. These different facets of our movement capabilities all contribute to better overall function and load-tolerance capacity. As an added bonus, because most styles of yoga are bodyweight only and move at a very moderate speed, yoga is also a generally very accessible and safe movement modality.”</p> <p style="font-size: medium; font-weight: 400;">Yoga is the ultimate self-care activity. <a href="https://gaiam.innovations.co.nz/p/gaiam-yoga/accessories/27-73312-gaiam-performance-hold-everything-yoga-backpack-bag?affiliate=GAIAM60" target="_blank" rel="noopener">Whether you do it at a studio or in the park, this handy yoga backpack bag stores everything you need for a calm yoga workout.</a></p> <p style="font-size: medium; font-weight: 400;"><strong>This article, written by </strong><span style="font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen, Ubuntu, Cantarell, 'Open Sans', 'Helvetica Neue', sans-serif; font-size: medium;"><strong>Kiersten Hickman,</strong> </span><strong style="font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen, Ubuntu, Cantarell, 'Open Sans', 'Helvetica Neue', sans-serif;">originally appeared on <a href="https://www.readersdigest.co.nz/culture/6-major-benefits-of-doing-yoga-every-day-from-experts" target="_blank" rel="noopener">Reader's Digest</a>.</strong></p> <p style="font-size: medium; font-weight: 400;"><em>Images: Shutterstock | Getty</em></p>

Why do I need to get up during the night to wee? Is this normal?

It’s one of the most commonly reported <a href="https://pubmed.ncbi.nlm.nih.gov/32249998/">bothersome urinary symptoms</a> (others include urgency and poor stream).</p> <p>So what causes nocturia, and how can it affect wellbeing?</p> <h2>A range of causes</h2> <p>Nocturia can be caused by a variety of <a href="https://www.health.gov.au/sites/default/files/nocturia-going-to-the-toilet-at-night_0.pdf">medical conditions</a>, such as heart or kidney problems, poorly controlled diabetes, bladder infections, an <a href="https://www.nature.com/articles/s41598-023-44916-8">overactive bladder</a>, or gastrointestinal issues. Other causes include pregnancy, <a href="https://onlinelibrary.wiley.com/doi/10.1002/nau.24839">medications</a> and consumption of alcohol or caffeine before bed.</p> <p>While nocturia causes disrupted sleep, the reverse is true as well. Having broken sleep, or <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4055528/">insomnia</a>, can also cause nocturia.</p> <p>When we sleep, an antidiuretic hormone is released that slows down the rate at which our <a href="https://theconversation.com/is-urine-sterile-do-urine-therapies-work-experts-debunk-common-pee-myths-191862">kidneys produce urine</a>. If we lie awake at night, less of this hormone <a href="https://journals.physiology.org/doi/full/10.1152/ajprenal.00025.2023">is released</a>, meaning we continue to produce normal rates of urine. This can accelerate the rate at which we fill our bladder and need to get up during the night.</p> <p>Stress, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4153377/">anxiety</a> and watching television <a href="https://www.ncbi.nlm.nih.gov/books/NBK518987">late into the night</a> are common causes of insomnia.</p> <h2>Effects of nocturia on daily functioning</h2> <p>The recommended amount of sleep for adults is between <a href="https://www.nhlbi.nih.gov/health/sleep/how-much-sleep">seven and nine hours</a> per night.

Why and how often do I need to wash makeup brushes and sponges?

<p><em><a href="https://theconversation.com/profiles/enzo-palombo-249510">Enzo Palombo</a>, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a> and <a href="https://theconversation.com/profiles/rosalie-hocking-1428271">Rosalie Hocking</a>, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a></em></p> <p>From the bristles of brushes to the porous surfaces of sponges, your makeup kit can harbour a host of bacteria and fungi.</p> <p>These potentially hazardous contaminants can originate not only from the cosmetics themselves, but also from the very surface of our skin.</p> <p>So, how can we keep things hygienic and avoid microbial growth on makeup brushes and sponges? Here’s what you need to know.</p> <h2>How do germs and fungi get in my brushes and sponges?</h2> <p>Germs and fungi can make their way into your makeup kit in lots of ways.</p> <p>Ever flushed a toilet with the lid open with your makeup brushes nearby? There’s a good chance <a href="https://theconversation.com/mobile-phones-are-covered-in-germs-disinfecting-them-daily-could-help-stop-diseases-spreading-135318">faecal particles</a> have landed on them.</p> <p>Perhaps a family member or housemate has used your eyeshadow brush when you weren’t looking, and transferred some microbes across in the process.</p> <p>Bacteria that trigger a pimple outbreak can be easily transferred from the surface of your skin to a makeup brush or sponge.</p> <p>And tiny little mites called Demodex mites, which have been linked to certain rashes and acne, live on your skin, as well, and so may end up in your sponge or brushes.</p> <p>Bacterial contamination of <a href="https://pubmed.ncbi.nlm.nih.gov/38020232/">lip cosmetics</a>, in particular, can pose a risk of skin and eye infections (so keep that in mind if you use lip brushes). Lipsticks are frequently contaminated with bacteria such as <em>Staphylococcus aureus</em>, <em>E. coli</em>, and <em>Streptococcus pneumoniae</em>.</p> <p>Low-quality cosmetics are more likely to have higher and more diverse microbial growth compared to <a href="https://www.sciencedirect.com/science/article/pii/S1319562X23002978?pes=vor">high-quality cosmetics</a>.</p> <p>Brushes exposed to sensitive areas like the eyes, mouth and nose are particularly susceptible to being potential sources of infection.</p> <p>The range of conditions caused by these microorganisms includes:</p> <ul> <li> <p>abscesses</p> </li> <li> <p>skin and soft tissue infections</p> </li> <li> <p>skin lesions</p> </li> <li> <p>rashes</p> </li> <li> <p>and dermatitis.</p> </li> </ul> <p>In severe cases, infections can lead to invasion of the bloodstream or deep tissues.</p> <p>Commercially available cosmetics contain varying amounts and types of preservatives aimed at inhibiting the growth of fungi and bacteria.</p> <p>But when you apply makeup, different cosmetics with unique formulations of preservatives can become mixed. When a preservative meant for one product mixes with others, it might not work as well because they have different water amounts or pH levels.</p> <p>So preservatives are not foolproof. We also need to observe good hygiene practices when it comes to brushes and other cosmetics applicators.</p> <h2>Keeping brushes clean</h2> <p>Start with the basics: never <a href="https://www.semanticscholar.org/paper/Isolation-of-Pathogenic-Microbes-from-Beauty-Salons-Hassan-Hamad/0199635290628fe326fcd04a2b8a2422884a8240">share makeup brushes or sponges</a>. Everyone carries different microbes on their skin, so sharing brushes and sponges means you are also sharing germs and fungi.</p> <p>If you need to share makeup, use something disposable to apply it, or make sure any shared brushes are washed and sterilised before the next person uses it.</p> <p>Clean makeup brushes by washing with hot soapy water and rinsing thoroughly.</p> <p>How often? Stick to a cleaning routine you can repeat with consistency (as opposed to a deep clean that is done annually). <a href="https://www.aad.org/public/everyday-care/skin-care-secrets/routine/clean-your-makeup-brushes#:%7E:text=To%20protect%20your%20skin%20and,every%207%20to%2010%20days.">Once a week</a> might be a good goal for some, while others may need to wash more regularly if they are heavy users of makeup.</p> <p>Definitely wash straight away if someone else has used your brushes or sponges. And if you’ve had an eye infection such as conjunctivitis, ensure you clean applicators thoroughly after the infection has resolved.</p> <p>You can use bactericidal soap, 70% ethanol or chlorhexidine solutions to wash. Just make sure you wash very thoroughly with hot water after, as some of these things can irritate your skin. (While some people online say alcohol can degrade brushes and sponges, opinion seems to be mixed; in general, most disinfectants are unlikely to cause significant corrosion.)</p> <p>For some brushes, heating or steaming them and letting them dry may also be an effective sterilisation method once they are washed with detergent. Microwaving sponges isn’t a good idea because while the heat generated by a domestic microwave would kill microbes, it would need temperatures approaching 100°C for a decent period of time (at least several minutes). The heat could melt some parts of the sponge and hot materials could be a scalding hazard.</p> <p>Once clean, ensure brushes and sponges are stored in a dry place away from water sources (and not near an open toilet).</p> <p>If you’re having makeup applied professionally, brushes and applicators should be sterilised or changed from person to person.</p> <h2>Should I wash them with micellar water?</h2> <p>No.</p> <p>Not only is this expensive, it’s unnecessary. The same benefits can be achieved with cheaper detergents or alcohol (just rinse brushes carefully afterwards).</p> <p>Disinfection methods such as using bactericidal soap, 70% ethanol, or chlorhexidine are all very good at reducing the amount of microbes on your brushes and sponges.<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/220280/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/enzo-palombo-249510"><em>Enzo Palombo</em></a><em>, Professor of Microbiology, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a> and <a href="https://theconversation.com/profiles/rosalie-hocking-1428271">Rosalie Hocking</a>, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a></em></p> <p><em>Image credits: Getty Images </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

I want to eat healthily. So why do I crave sugar, salt and carbs?

<p><em><a href="https://theconversation.com/profiles/hayley-oneill-1458016">Hayley O'Neill</a>, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a></em></p> <p>We all want to eat healthily, especially as we reset our health goals at the start of a new year. But sometimes these plans are sabotaged by powerful cravings for sweet, salty or carb-heavy foods.</p> <p>So why do you crave these foods when you’re trying to improve your diet or lose weight? And what can you do about it?</p> <p>There are many reasons for craving specific foods, but let’s focus on four common ones:</p> <h2>1. Blood sugar crashes</h2> <p>Sugar is a key energy source for all animals, and its taste is one of the most basic sensory experiences. Even without specific sweet taste receptors on the tongue, a strong preference for sugar can develop, indicating a mechanism beyond taste alone.</p> <p>Neurons <a href="https://www.nature.com/articles/s41593-021-00982-7">responding to sugar</a> are activated when sugar is delivered to the gut. This can increase appetite and make you want to consume more. Giving into cravings also drives an appetite for more sugar.</p> <p>In the long term, research suggests a high-sugar diet can affect <a href="https://www.bmj.com/content/369/bmj.m2382">mood</a>, digestion and <a href="https://pubmed.ncbi.nlm.nih.gov/33339337/">inflammation</a> in the <a href="https://www.science.org/doi/10.1126/scitranslmed.aay6218?url_ver=Z39.88-2003&amp;rfr_id=ori:rid:crossref.org&amp;rfr_dat=cr_pub%20%200pubmed">gut</a>.</p> <p>While there’s a lot of <a href="https://www.sciencedirect.com/science/article/pii/S0149763402000040?via%3Dihub#aep-section-id23">variation between individuals</a>, regularly eating sugary and high-carb foods can lead to <a href="https://pubmed.ncbi.nlm.nih.gov/30951762/">rapid spikes and crashes</a> in blood sugar levels. When your blood sugar drops, your body can respond by craving quick sources of energy, often in the form of sugar and carbs because these deliver the fastest, most easily accessible form of energy.</p> <h2>2. Drops in dopamine and serotonin</h2> <p>Certain neurotransmitters, such as <a href="https://pubmed.ncbi.nlm.nih.gov/30595479/">dopamine</a>, are involved in the reward and pleasure centres of the brain. Eating sugary and carb-rich foods can trigger the release of dopamine, creating a pleasurable experience and reinforcing the craving.</p> <p>Serotonin, the feel-good hormone, suppresses <a href="https://www.sciencedirect.com/science/article/pii/S1569733910700886">appetite</a>. Natural changes in serotonin can influence daily fluctuations in mood, energy levels and attention. It’s also associated with eating more <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5829131/">carb-rich snacks in the afternoon</a>.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/21985780/">Low carb diets</a> may reduce serotonin and lower mood. However, a recent systematic review suggests little association between these diets and risk for <a href="https://www.sciencedirect.com/science/article/pii/S0165032722013933?via%3Dihub">anxiety and depression</a>.</p> <p>Compared to men, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4189179/">women tend to crave more carb rich foods</a>. Feeling irritable, tired, depressed or experiencing carb cravings are part of premenstrual <a href="https://pubmed.ncbi.nlm.nih.gov/29218451/">symptoms</a> and could be <a href="https://www.ncbi.nlm.nih.gov/books/NBK560698/">linked to</a> reduced <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9928757/">serotonin levels</a>.</p> <h2>3. Loss of fluids and drops in blood sugar and salt</h2> <p>Sometimes our bodies crave the things they’re missing, such as hydration or even salt. A low-carb diet, for example, <a href="https://www.ncbi.nlm.nih.gov/books/NBK537084/">depletes</a> insulin levels, decreasing sodium and water retention.</p> <p><a href="https://www.sciencedirect.com/science/article/pii/S1933287419302673">Very low-carb diets</a>, like ketogenic diets, induce “ketosis”, a metabolic state where the body switches to using fat as its primary energy source, moving away from the usual dependence on carbohydrates.</p> <p>Ketosis is often associated with increased urine production, further contributing to potential fluid loss, electrolyte imbalances and salt cravings.</p> <h2>4. High levels of stress or emotional turmoil</h2> <p><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4214609/">Stress</a>, boredom and emotional turmoil can lead to cravings for comfort foods. This is because stress-related hormones can impact our appetite, satiety (feeling full) and food preferences.</p> <p>The stress hormone <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3425607/">cortisol</a>, in particular, can drive cravings for <a href="https://www.sciencedirect.com/science/article/abs/pii/S0306453000000354">sweet comfort foods</a>.</p> <p>A <a href="https://www.sciencedirect.com/science/article/abs/pii/S0306453000000354">2001 study</a> of 59 premenopausal women subjected to stress revealed that the stress led to higher calorie consumption.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/37295418/">A more recent study</a> found chronic stress, when paired with high-calorie diet, increases food intake and a preference for sweet foods. This shows the importance of a healthy diet during stress to prevent weight gain.</p> <h2>What can you do about cravings?</h2> <p>Here are four tips to curb cravings:</p> <p><strong>1) don’t cut out whole food groups.</strong> Aim for a well-balanced diet and make sure you include:</p> <ul> <li> <p><em>sufficient protein</em> in your meals to help you feel full and reduce the urge to snack on sugary and carb-rich foods. Older adults should aim for 20–40g protein per meal with a particular focus on <a href="https://onlinelibrary.wiley.com/doi/epdf/10.1111/jhn.12838">breakfast and lunch</a> and an overall daily protein intake of at least <a href="https://apps.who.int/iris/handle/10665/43411">0.8g</a> per kg of body weight for <a href="https://pubmed.ncbi.nlm.nih.gov/35187864/">muscle health</a></p> </li> <li> <p><em>fibre-rich foods</em>, such as vegetables and whole grains. These make you feel full and <a href="https://pubmed.ncbi.nlm.nih.gov/32142510/">stabilise your blood sugar</a> levels. Examples include broccoli, quinoa, brown rice, oats, beans, lentils and bran cereals. Substitute refined carbs high in sugar like processed snack bars, soft drink or baked goods for more complex ones like whole grain bread or wholewheat muffins, or nut and seed bars or energy bites made with chia seeds and oats</p> </li> </ul> <p><strong>2) manage your stress levels.</strong> Practise stress-reduction techniques like meditation, deep breathing, or yoga to manage emotional triggers for cravings. Practising <a href="https://pubmed.ncbi.nlm.nih.gov/30570305/">mindful eating</a>, by eating slowly and tuning into bodily sensations, can also reduce daily calorie intake and curb cravings and stress-driven eating</p> <p><strong>3) get enough sleep.</strong> Aim for <a href="https://pubmed.ncbi.nlm.nih.gov/33054337/">seven to eight</a> hours of quality sleep per night, with a minimum of seven hours. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9031614/">Lack of sleep</a> can disrupt hormones that regulate hunger and cravings</p> <p><strong>4) control your portions.</strong> If you decide to indulge in a treat, control your portion size to avoid overindulging.</p> <p>Overcoming cravings for sugar, salt and carbs when trying to eat healthily or lose weight is undoubtedly a formidable challenge. Remember, it’s a journey, and setbacks may occur. Be patient with yourself – your success is not defined by occasional cravings but by your ability to manage and overcome them.<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/212114/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/hayley-oneill-1458016">Hayley O'Neill</a>, Assistant Professor, Faculty of Health Sciences and Medicine, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a></em></p> <p><em>Image credits: Getty Images </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Why do I keep getting urinary tract infections? And why are chronic UTIs so hard to treat?

<p><em><a href="https://theconversation.com/profiles/iris-lim-1204657">Iris Lim</a>, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a></em></p> <p>Dealing with chronic urinary tract infections (UTIs) means facing more than the occasional discomfort. It’s like being on a never ending battlefield against an unseen adversary, making simple daily activities a trial.</p> <p>UTIs happen when bacteria sneak into the urinary system, causing pain and frequent trips to the bathroom.</p> <p>Chronic UTIs take this to the next level, coming back repeatedly or never fully going away despite treatment. <a href="https://www.ncbi.nlm.nih.gov/books/NBK557479/">Chronic UTIs</a> are typically diagnosed when a person experiences two or more infections within six months or three or more within a year.</p> <p>They can happen to anyone, but some are more prone due to their <a href="https://www.urologyhealth.org/urology-a-z/u/urinary-tract-infections-in-adults">body’s makeup or habits</a>. Women are more likely to get UTIs than men, due to their shorter urethra and hormonal changes during menopause that can decrease the protective lining of the urinary tract. Sexually active people are also at greater risk, as bacteria can be transferred around the area.</p> <p>Up to <a href="https://www.urologyhealth.org/urology-a-z/u/urinary-tract-infections-in-adults#Related%20Resources">60% of women</a> will have at least one UTI in their lifetime. While effective treatments exist, <a href="https://www.health.harvard.edu/bladder-and-bowel/when-urinary-tract-infections-keep-coming-back#:%7E:text=Your%20urine%20might%20be%20cloudy,they%20take%20on%20your%20life.">about 25%</a> of women face recurrent infections within six months. Around <a href="https://sciendo.com/article/10.33073/pjm-2019-048?tab=article">20–30%</a> of UTIs don’t respond to standard antibiotic. The challenge of chronic UTIs lies in bacteria’s ability to shield themselves against treatments.</p> <h2>Why are chronic UTIs so hard to treat?</h2> <p>Once thought of as straightforward infections cured by antibiotics, we now know chronic UTIs are complex. The cunning nature of the bacteria responsible for the condition allows them to hide in bladder walls, out of antibiotics’ reach.</p> <p>The bacteria form biofilms, a kind of protective barrier that makes them nearly impervious to standard antibiotic treatments.</p> <p>This ability to evade treatment has led to a troubling <a href="https://theconversation.com/rising-antibiotic-resistance-in-utis-could-cost-australia-1-6-billion-a-year-by-2030-heres-how-to-curb-it-149543">increase in antibiotic resistance</a>, a global health concern that renders some of the conventional treatments ineffective.</p> <p>Antibiotics need to be advanced to keep up with evolving bacteria, in a similar way to the flu vaccine, which is updated annually to combat the latest strains of the flu virus. If we used the same flu vaccine year after year, its effectiveness would wane, just as overused antibiotics lose their power against bacteria that have adapted.</p> <p>But fighting bacteria that resist antibiotics is much tougher than updating the flu vaccine. Bacteria change in ways that are harder to predict, making it more challenging to create new, effective antibiotics. It’s like a never-ending game where the bacteria are always one step ahead.</p> <p>Treating chronic UTIs still relies heavily on antibiotics, but doctors are getting crafty, changing up medications or prescribing low doses over a longer time to outwit the bacteria.</p> <p>Doctors are also placing a greater emphasis on thorough diagnostics to accurately identify chronic UTIs from the outset. By asking detailed questions about the duration and frequency of symptoms, health-care providers can better distinguish between isolated UTI episodes and chronic conditions.</p> <p>The approach to initial treatment can significantly influence the likelihood of a UTI becoming chronic. Early, targeted therapy, based on the specific bacteria causing the infection and its antibiotic sensitivity, may reduce the risk of recurrence.</p> <p>For post-menopausal women, <a href="https://link.springer.com/article/10.1007/s00192-020-04397-z">estrogen therapy</a> has shown promise in reducing the risk of recurrent UTIs. After menopause, the decrease in estrogen levels can lead to changes in the urinary tract that makes it more susceptible to infections. This treatment restores the balance of the vaginal and urinary tract environments, making it less likely for UTIs to occur.</p> <p>Lifestyle changes, such as <a href="https://journals.lww.com/co-nephrolhypertens/FullText/2013/05001/Impact_of_fluid_intake_in_the_prevention_of.1.aspx">drinking more water</a> and practising good hygiene like washing hands with soap after going to the toilet and the recommended front-to-back wiping for women, also play a big role.</p> <p>Some swear by cranberry juice or supplements, though researchers are still figuring out <a href="https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD001322.pub2/full">how effective these remedies truly are</a>.</p> <h2>What treatments might we see in the future?</h2> <p>Scientists are currently working on new treatments for chronic UTIs. One promising avenue is the development of <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10052183/pdf/pathogens-12-00359.pdf">vaccines</a> aimed at preventing UTIs altogether, much like flu shots prepare our immune system to fend off the flu.</p> <p>Another new method being looked at is called <a href="https://link.springer.com/article/10.1007/s12223-019-00750-y">phage therapy</a>. It uses special viruses called bacteriophages that go after and kill only the bad bacteria causing UTIs, while leaving the good bacteria in our body alone. This way, it doesn’t make the bacteria resistant to treatment, which is a big plus.</p> <p>Researchers are also exploring the potential of <a href="https://www.mdpi.com/2079-6382/12/1/167">probiotics</a>. Probiotics introduce beneficial bacteria into the urinary tract to out-compete harmful pathogens. These good bacteria work by occupying space and resources in the urinary tract, making it harder for harmful pathogens to establish themselves.</p> <p>Probiotics can also produce substances that inhibit the growth of harmful bacteria and enhance the body’s immune response.</p> <p>Chronic UTIs represent a stubborn challenge, but with a mix of current treatments and promising research, we’re getting closer to a day when chronic UTIs are a thing of the past.<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/223008/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/iris-lim-1204657">I<em>ris Lim</em></a><em>, Assistant Professor, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a></em></p> <p><em>Image credits: Getty Images</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

The one thing you must do before retirement

<p>When you think about planning for retirement, the standard advice is to take a thorough look at your superannuation and finances. Although money is undoubtedly an important aspect of retirement planning, making a plan for your emotion and physical wellbeing is just as crucial.</p> <p>New research from the UK has found that retirement can have a negative impact on your mental and physical health. The study, published by the Institute of Economic Affairs, looked at the impact of retirement on 7,000 people aged 50 to 70, and found that while retirement gives most people a small health booth, over the medium to long-term it causes a “drastic decline in health”. </p> <p>For both men and women, retirement decreases the likelihood of "very good” or "excellent" self-reported health by 40 per cent, increases risk for depression by 40 per cent, and diagnosis of a physical illness by 60 per cent. The study’s lead author, Gabriel Sahlgren, noted: "Work, especially paid work, gives many people a sense of purpose. Losing that may lead to declines in health."</p> <p>The lesson: Make a plan for your emotional and physical health.</p> <p>“Don't wait until you retire to decide how you're going to keep busy,” Dave Bernard, retirement blogger and author of Are You Just Existing and Calling it a Life?, told Prevention, adding, “And you need to look well beyond the first six months.”</p> <p>Just as it’s necessary to make sure your finances are in order before retirement, it’s crucial to ask yourself: What will my new sense of purpose in retirement be?</p> <p>“Many times, adults might not think about what it actually means to be retired, or they think about retirement in abstract terms,” says Angela Curl, an assistant professor in the University of Missouri School of Social Work.</p> <p>She says you need to make concrete plans for retirement. “If you want to volunteer when you are retired, ask yourself where and how often. Having specific plans and steps to follow will help you enter retirement more easily,” says Curl.</p> <p>Creating a plan of how you’ll spend your time when you retire will keep you mentally and physically strong, ensuring that you’ll be healthy enough to enjoy your well-deserved retirement.</p> <p><em>Image credits: Getty Images </em></p>

What ‘psychological warfare’ tactics do scammers use, and how can you protect yourself?

<p><em><a href="https://theconversation.com/profiles/mike-johnstone-106590">Mike Johnstone</a>, <a href="https://theconversation.com/institutions/edith-cowan-university-720">Edith Cowan University</a> and <a href="https://theconversation.com/profiles/georgia-psaroulis-1513050">Georgia Psaroulis</a>, <a href="https://theconversation.com/institutions/edith-cowan-university-720">Edith Cowan University</a></em></p> <p>Not a day goes by without a headline <a href="https://www.vice.com/en/article/qjvaym/people-share-worst-scam-stories">about a victim being scammed</a> and losing money. We are constantly warned about new scams and staying safe from cybercriminals. Scamwatch has <a href="https://www.scamwatch.gov.au/research-and-resources/tools-resources/online-resources/spot-the-scam-signs">no shortage of resources</a>, too.</p> <p>So why are people still getting scammed, and sometimes spectacularly so?</p> <p>Scammers use sophisticated psychological techniques. They exploit our deepest human vulnerabilities and bypass rational thought to tap into our emotional responses.</p> <p>This “<a href="https://www.thecut.com/article/amazon-scam-call-ftc-arrest-warrants.html">psychological warfare</a>” coerces victims into making impulsive decisions. Sometimes scammers spread their methods around many potential victims to see who is vulnerable. Other times, criminals focus on a specific person.</p> <p>Let’s unpack some of these psychological techniques, and how you can defend against them.</p> <h2>1. Random phone calls</h2> <p>Scammers start with small requests to establish a sense of commitment. After agreeing to these minor requests, we are more likely to comply with larger demands, driven by a desire to act consistently.</p> <p>The call won’t come from a number in your contacts or one you recognise, but the scammer may pretend to be someone you’ve engaged to work on your house, or perhaps one of your children using a friend’s phone to call you.</p> <p>If it is a scammer, maybe keeping you on the phone for a long time gives them an opportunity to find out things about you or people you know. They can use this info either immediately or at a later date.</p> <h2>2. Creating a sense of urgency</h2> <p>Scammers fabricate scenarios that require immediate action, like claiming a bank account is at risk of closure or an offer is about to expire. This tactic aims to prevent victims from assessing the situation logically or seeking advice, pressuring them into rushed decisions.</p> <p>The scammer creates an artificial situation in which you are frightened into doing something you wouldn’t ordinarily do. Scam calls <a href="https://theconversation.com/we-have-filed-a-case-under-your-name-beware-of-tax-scams-theyll-be-everywhere-this-eofy-162171">alleging to be from the Australian Tax Office</a> (ATO) are a great example. You have a debt to pay (apparently) and things will go badly if you don’t pay <em>right now</em>.</p> <p>Scammers play on your emotions to provoke reactions that cloud judgement. They may threaten legal trouble to instil fear, promise high investment returns to exploit greed, or share fabricated distressing stories to elicit sympathy and financial assistance.</p> <h2>3. Building rapport with casual talk</h2> <p>Through extended conversation, scammers build a psychological commitment to their scheme. No one gets very far by just demanding your password, but it’s natural to be friendly with people who are friendly towards us.</p> <p>After staying on the line for long periods of time, the victim also becomes cognitively fatigued. This not only makes the victim more open to suggestions, but also isolates them from friends or family who might recognise and counteract the scam.</p> <h2>4. Help me to help you</h2> <p>In this case, the scammer creates a situation where they help you to solve a real or imaginary problem (that they actually created). They work their “IT magic” and the problem goes away.</p> <p>Later, they ask you for something you wouldn’t normally do, and you do it because of the “social debt”: they helped you first.</p> <p>For example, a hacker might attack a corporate network, causing it to slow down. Then they call you, pretending to be from your organisation, perhaps as a recent hire not yet on the company’s contact list. They “help” you by turning off the attack, leaving you suitably grateful.</p> <p>Perhaps a week later, they call again and ask for sensitive information, such as the CEO’s password. You <em>know</em> company policy is to not divulge it, but the scammer will ask if you remember them (of course you do) and come up with an excuse for why they really need this password.</p> <p>The balance of the social debt says you will help them.</p> <h2>5. Appealing to authority</h2> <p>By posing as line managers, officials from government agencies, banks, or other authoritative bodies, scammers exploit our natural tendency to obey authority.</p> <p>Such scams operate at varying levels of sophistication. The simple version: your manager messages you with an <em>urgent</em> request to purchase some gift cards and send through their numbers.</p> <p>The complex version: your manager calls and asks to urgently transfer a large sum of money to an account you don’t recognise. You do this because <a href="https://www.wsj.com/articles/fraudsters-use-ai-to-mimic-ceos-voice-in-unusual-cybercrime-case-11567157402">it sounds exactly</a> like your manager on the phone – but the scammer <a href="https://www.forbes.com/sites/thomasbrewster/2021/10/14/huge-bank-fraud-uses-deep-fake-voice-tech-to-steal-millions/?sh=1329b80e7559">is using a voice deepfake</a>. In a recent major case in Hong Kong, such a scam even involved a <a href="https://edition.cnn.com/2024/02/04/asia/deepfake-cfo-scam-hong-kong-intl-hnk/index.html">deepfake video call</a>.</p> <p>This is deeply challenging because artificial intelligence tools, such as Microsoft’s VALL-E, can create <a href="https://arstechnica.com/information-technology/2023/01/microsofts-new-ai-can-simulate-anyones-voice-with-3-seconds-of-audio/">a voice deepfake</a> using just three seconds of sampled audio from a real person.</p> <h2>How can you defend against a scam?</h2> <p>First and foremost, <strong>verify identity</strong>. Find another way to contact the person to verify who they are. For example, you can call a generic number for the business and ask to be connected.</p> <p>In the face of rampant voice deepfakes, it can be helpful to <strong>agree on a “safe word” with your family members</strong>. If they call from an unrecognised number and you don’t hear the safe word just hang up.</p> <p>Watch out for <strong>pressure tactics</strong>. If the conversation is moving too fast, remember that someone else’s problem is not yours to solve. Stop and run the problem past a colleague or family member for a sanity check. A legitimate business will have no problem with you doing this.</p> <p>Lastly, if you are not sure about even the slightest detail, the simplest thing is to hang up or not respond. If you really owe a tax debt, the ATO will write to you.<!-- Below is The Conversation's page counter tag.

How to navigate a parent’s cancer diagnosis – like Princes William and Harry will now have to do

<p><em><a href="https://theconversation.com/profiles/lydia-harkin-1510450">Lydia Harkin</a>, <a href="https://theconversation.com/institutions/nottingham-trent-university-1338">Nottingham Trent University</a></em></p> <p>King Charles’ <a href="https://www.bbc.co.uk/news/uk-68209998">cancer diagnosis</a> means the royal family has joined the approximately 3 million families in the UK affected by the disease. His family has already gathered around in support. William, Prince of Wales, has taken over some public duties for his father. And younger son Harry, who lives in California, flew to the UK to visit after the diagnosis was announced.</p> <p>If you, like William and Harry, are navigating a parent’s diagnosis, you are not alone. Around 400,000 people are <a href="https://www.macmillan.org.uk/about-us/what-we-do/research/cancer-statistics-fact-sheet">diagnosed</a> each year. This can be a <a href="https://doi.org/10.1002/pon.4287">frightening</a> and difficult time for families, and can change family dynamics.</p> <p>Adult children may find themselves offering emotional and practical support for a parent in a way that has not been required before, through managing medications and symptoms, travel to medical appointments, help with meal preparation and financial support.</p> <p>It can be rewarding to support a loved one and an important way to actively work together, but it can also be stressful. <a href="https://doi.org/10.1002/pon.4056">Studies have found</a> that family caregivers are generally more anxious and more likely to hide their emotional distress when compared with their family member with cancer.</p> <h2>Being a supportive family, even in conflict</h2> <p>Family support can act as a <a href="https://doi.org/10.1002/ejsp.2333">“social cure”</a> against the stress of a life-changing illness. The social cure theory proposes that being a part of a social group (or multiple groups) has benefits for our health and wellbeing. Social groups, particularly those with whom we strongly identify, like families, provide support and help us to combat times of stress.</p> <p>The key psychological component here is that people feel they belong to and identify with their groups. While undergoing cancer treatment, someone may not be able to participate in their usual social groups – through work or hobbies – as much as they used to. These groups may then become incompatible with a person’s new identity as a cancer survivor.</p> <p>Of course, not all families work together harmoniously, and may be in conflict through divorce, separation or estrangement. Social psychologists have <a href="https://doi.org/10.1111/bjso.12155">found that</a> “incompatible” social groups can lead to poorer mental health.</p> <p>Separated families can still come together and be a helpful social group, but they must offer the kind of support that their loved one needs. To figure this out, it is important to think about the person’s <a href="https://doi.org/10.1002/ejsp.2333">identity</a> within the family.</p> <p>For example, a father may view his identity as an advisor, but a cancer diagnosis requires him to be cared for and to seek advice. He may feel a sense of loss for his typical family role, a loss of meaning and of control.</p> <p>However, if his family communicates openly about the difficulties they are all facing, the father may be able to continue to advise his family, in addition to receiving their advice. This can help to maintain his sense of identity as an advisor within his family, while navigating a new status as a cancer survivor.</p> <h2>Communication and support networks</h2> <p>Cancer throws patients and their loved ones into a complex health system, often for the first time, where medical decisions and terminology become important every day. Understanding <a href="https://doi.org/10.1016/j.ejon.2014.03.012">the “language of cancer”</a> can help families feel more in control after a diagnosis.</p> <p>Equally important is communication within a family. Talking about the cancer, rather than treating it as a taboo topic, can improve <a href="https://doi.org/10.1016/j.ejon.2020.101841">mental health for both patients and their families</a>. It may also be an opportunity to empower patients and their loved ones to seek outside support, such as counselling.</p> <p>Families spread across geographical distances (like the royal family) can offer emotional support through regular phone calls or online tools. During the pandemic, <a href="https://doi.org/10.2196/42172">I developed</a> and trialled an app to help older adults combat loneliness. The app allowed them to see a digital map of their social groups, including family members.</p> <p>Your family member with cancer may feel like a burden. This is a common fear in older adulthood generally. But reminding them of how many people are in their lives – and how many people they support – can combat this feeling.</p> <p>Social media is one way to get more involved in these reciprocal support networks. In my work, families affected by cancer have reported using online communities to <a href="https://doi.org/10.1007/s11764-017-0616-1">better understand what their family is going through</a>. Private social media groups <a href="https://doi.org/10.1177/2055207619898993">dedicated to illness</a> can be helpful spaces to meet other patients and families, share experiences and normalise cancer.</p> <p>Cancer communities exist on <a href="https://doi.org/10.4103%2Fijpvm.IJPVM_36_19">Instagram</a>, on <a href="https://doi.org/10.1007/s00345-018-2254-2">YouTube and X/Twitter</a> and through registered cancer charities like <a href="https://www.macmillan.org.uk/">Macmillan Cancer Support</a>. These online resources all provide a way to build a network following a cancer diagnosis.</p> <p>Just as group identification is important within families, having more groups to connect to can act as a buffer during stressful times and help you all cope with your new reality.<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/223214/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/lydia-harkin-1510450"><em>Lydia Harkin</em></a><em>, Principal Lecturer in Psychology, <a href="https://theconversation.com/institutions/nottingham-trent-university-1338">Nottingham Trent University</a></em></p> <p><em>Image credits: Getty Images </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

How much weight do you actually need to lose? It might be a lot less than you think

<p><em><a href="https://theconversation.com/profiles/nick-fuller-219993">Nick Fuller</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>If you’re one of the <a href="https://www.finder.com.au/new-years-resolutions-statistics">one in three</a> Australians whose New Year’s resolution involved losing weight, it’s likely you’re now contemplating what weight-loss goal you should actually be working towards.</p> <p>But type “setting a weight loss goal” into any online search engine and you’ll likely be left with more questions than answers.</p> <p>Sure, the many weight-loss apps and calculators available will make setting this goal seem easy. They’ll typically use a body mass index (BMI) calculator to confirm a “healthy” weight and provide a goal weight based on this range.</p> <p>Your screen will fill with trim-looking influencers touting diets that will help you drop ten kilos in a month, or ads for diets, pills and exercise regimens promising to help you effortlessly and rapidly lose weight.</p> <p>Most sales pitches will suggest you need to lose substantial amounts of weight to be healthy – making weight loss seem an impossible task. But the research shows you don’t need to lose a lot of weight to achieve health benefits.</p> <h2>Using BMI to define our target weight is flawed</h2> <p>We’re a society fixated on numbers. So it’s no surprise we use measurements and equations to score our weight. The most popular is BMI, a measure of our body weight-to-height ratio.</p> <p>BMI classifies bodies as underweight, normal (healthy) weight, overweight or obese and can be a useful tool for weight and health screening.</p> <p>But it shouldn’t be used as the single measure of what it means to be a healthy weight when we set our weight-loss goals. This is <a href="https://theconversation.com/using-bmi-to-measure-your-health-is-nonsense-heres-why-180412">because</a> it:</p> <ul> <li> <p>fails to consider two critical factors related to body weight and health – body fat percentage and distribution</p> </li> <li> <p>does not account for significant differences in body composition based on gender, ethnicity and age.</p> </li> </ul> <h2>How does losing weight benefit our health?</h2> <p>Losing just 5–10% of our body weight – between 6 and 12kg for someone weighing 120kg – can significantly improve our health in four key ways.</p> <p><strong>1. Reducing cholesterol</strong></p> <p>Obesity increases the chances of having too much low-density lipoprotein (LDL) cholesterol – also known as bad cholesterol – because carrying excess weight changes how our bodies produce and manage lipoproteins and triglycerides, another fat molecule we use for energy.</p> <p>Having too much bad cholesterol and high triglyceride levels is not good, narrowing our arteries and limiting blood flow, which increases the risk of heart disease, heart attack and stroke.</p> <p>But <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4987606/">research</a> shows improvements in total cholesterol, LDL cholesterol and triglyceride levels are evident with just 5% weight loss.</p> <p><strong>2. Lowering blood pressure</strong></p> <p>Our blood pressure is considered high if it reads more than 140/90 on at least two occasions.</p> <p>Excess weight is <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7082272/">linked to</a> high blood pressure in <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7082272/">several ways</a>, including changing how our sympathetic nervous system, blood vessels and hormones regulate our blood pressure.</p> <p>Essentially, high blood pressure makes our heart and blood vessels work harder and less efficiently, damaging our arteries over time and increasing our risk of heart disease, heart attack and stroke.</p> <p>Like the improvements in cholesterol, a 5% weight loss <a href="https://onlinelibrary.wiley.com/doi/10.1002/oby.21358">improves</a> both systolic blood pressure (the first number in the reading) and diastolic blood pressure (the second number).</p> <p>A <a href="https://www.ahajournals.org/doi/10.1161/01.hyp.0000094221.86888.ae">meta-analysis of 25 trials</a> on the influence of weight reduction on blood pressure also found every kilo of weight loss improved blood pressure by one point.</p> <p><strong>3. Reducing risk for type 2 diabetes</strong></p> <p>Excess body weight is the primary manageable risk factor for type 2 diabetes, particularly for people carrying a lot of visceral fat around the abdomen (belly fat).</p> <p>Carrying this excess weight can cause fat cells to release pro-inflammatory chemicals that disrupt how our bodies regulate and use the insulin produced by our pancreas, leading to high blood sugar levels.</p> <p>Type 2 diabetes can lead to serious medical conditions if it’s not carefully managed, including damaging our heart, blood vessels, major organs, eyes and nervous system.</p> <p><a href="https://www.nejm.org/doi/full/10.1056/nejmoa012512">Research</a> shows just 7% weight loss reduces risk of developing type 2 diabetes by 58%.</p> <p><strong>4. Reducing joint pain and the risk of osteoarthritis</strong></p> <p>Carrying excess weight can cause our joints to become inflamed and damaged, making us more prone to osteoarthritis.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/21425246/">Observational studies</a> show being overweight doubles a person’s risk of developing osteoarthritis, while obesity increases the risk fourfold.</p> <p>Small amounts of weight loss alleviate this stress on our joints. <a href="https://pubmed.ncbi.nlm.nih.gov/15986358/">In one study</a> each kilogram of weight loss resulted in a fourfold decrease in the load exerted on the knee in each step taken during daily activities.</p> <h2>Focus on long-term habits</h2> <p>If you’ve ever tried to lose weight but found the kilos return almost as quickly as they left, you’re not alone.</p> <p>An <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5764193/">analysis</a> of 29 long-term weight-loss studies found participants regained more than half of the weight lost within two years. Within five years, they regained more than 80%.</p> <p>When we lose weight, we take our body out of its comfort zone and trigger its survival response. It then counteracts weight loss, triggering several <a href="https://pubmed.ncbi.nlm.nih.gov/25896063/">physiological responses</a> to defend our body weight and “survive” starvation.</p> <p>Just as the problem is evolutionary, the solution is evolutionary too. Successfully losing weight long-term comes down to:</p> <ul> <li> <p>losing weight in small manageable chunks you can sustain, specifically periods of weight loss, followed by periods of weight maintenance, and so on, until you achieve your goal weight</p> </li> <li> <p>making gradual changes to your lifestyle to ensure you form habits that last a lifetime.</p> </li> </ul> <p>Setting a goal to reach a healthy weight can feel daunting.

How do I handle it if my parent is refusing aged care? 4 things to consider

<p><em><a href="https://theconversation.com/profiles/lee-fay-low-98311">Lee-Fay Low</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>It’s a shock when we realise our parents aren’t managing well at home.</p> <p>Perhaps the house and garden are looking more chaotic, and Mum or Dad are relying more on snacks than nutritious meals. Maybe their grooming or hygiene has declined markedly, they are socially isolated or not doing the things they used to enjoy. They may be losing weight, have had a fall, aren’t managing their medications correctly, and are at risk of getting scammed.</p> <p>You’re worried and you want them to be safe and healthy. You’ve tried to talk to them about aged care but been met with swift refusal and an indignant declaration “I don’t need help – everything is fine!” Now what?</p> <p>Here are four things to consider.</p> <h2>1. Start with more help at home</h2> <p>Getting help and support at home can help keep Mum or Dad well and comfortable without them needing to move.</p> <p>Consider drawing up a roster of family and friends visiting to help with shopping, cleaning and outings. You can also use home aged care services – or a combination of both.</p> <p>Government subsidised home care services provide from one to 13 hours of care a week. You can get more help if you are a veteran or are able to pay privately. You can take advantage of things like rehabilitation, fall risk-reduction programs, personal alarms, stove automatic switch-offs and other technology aimed at increasing safety.</p> <p>Call <a href="https://www.myagedcare.gov.au/">My Aged Care</a> to discuss your options.</p> <h2>2. Be prepared for multiple conversations</h2> <p>Getting Mum or Dad to accept paid help can be tricky. Many families often have multiple conversations around aged care before a decision is made.</p> <p>Ideally, the older person feels supported rather than attacked during these conversations.</p> <p>Some families have a meeting, so everyone is coming together to help. In other families, certain family members or friends might be better placed to have these conversations – perhaps the daughter with the health background, or the auntie or GP who Mum trusts more to provide good advice.</p> <p>Mum or Dad’s main emotional support person should try to maintain their relationship. It’s OK to get someone else (like the GP, the hospital or an adult child) to play “bad cop”, while a different person (such as the older person’s spouse, or a different adult child) plays “good cop”.</p> <h2>3. Understand the options when help at home isn’t enough</h2> <p>If you have maximised home support and it’s not enough, or if the hospital won’t discharge Mum or Dad without extensive supports, then you may be <a href="https://academic.oup.com/gerontologist/article/60/8/1504/5863160">considering a nursing home</a> (also known as residential aged care in Australia).</p> <p>Every person has a legal right to <a href="https://humanrights.gov.au/our-work/9-your-right-choose-where-you-live">choose where we live</a> (unless they have lost capacity to make that decision).</p> <p>This means families can’t put Mum or Dad into residential aged care against their will. Every person also has the right to choose to take risks. People can choose to continue to live at home, even if it means they might not get help immediately if they fall, or eat poorly. We should respect Mum or Dad’s decisions, even if we disagree with them. Researchers call this “dignity of risk”.</p> <p>It’s important to understand Mum or Dad’s point of view. Listen to them. Try to figure out what they are feeling, and what they are worried might happen (which might not be rational).</p> <p>Try to understand what’s really important to their quality of life. Is it the dog, having privacy in their safe space, seeing grandchildren and friends, or something else?</p> <p>Older people are often understandably concerned about losing independence, losing control, and having strangers in their personal space.</p> <p>Sometimes families prioritise physical health over psychological wellbeing. But we need to consider both when considering nursing home admission.</p> <p><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9826495/">Research</a> suggests going into a nursing home temporarily increases loneliness, risk of depression and anxiety, and sense of losing control.</p> <p>Mum and Dad should be involved in the decision-making process about where they live, and when they might move.</p> <p>Some families start looking “just in case” as it often takes some time to <a href="https://www.abc.net.au/everyday/questions-to-ask-when-choosing-an-aged-care-home-for-a-loved-one/10302590">find the right nursing home</a> and there can be a wait.</p> <p>After you have your top two or three choices, take Mum or Dad to visit them. If this is not possible, take pictures of the rooms, the public areas in the nursing home, the menu and the activities schedule.</p> <p>We should give Mum or Dad information about their options and risks so they can make informed (and hopefully better) decisions.</p> <p>For instance, if they visit a nursing home and the manager says they can go on outings whenever they want, this might dispel a belief they are “locked up”.</p> <p>Having one or two weeks “respite” in a home may let them try it out before making the big decision about staying permanently. And if they find the place unacceptable, they can try another nursing home instead.</p> <h2>4. Understand the options if a parent has lost capacity to make decisions</h2> <p>If Mum or Dad have lost capacity to choose where they live, family may be able to make that decision in their best interests.</p> <p>If it’s not clear whether a person has capacity to make a particular decision, a medical practitioner can assess for that capacity.</p> <p>Mum or Dad may have appointed an <a href="https://www.tag.nsw.gov.au/wills/appoint-enduring-guardian/what-enduring-guardian">enduring guardian</a> to make decisions about their health and lifestyle decisions when they are not able to.</p> <p>An enduring guardian can make the decision that the person should live in residential aged care, if the person no longer has the capacity to make that decision themselves.</p> <p>If Mum or Dad didn’t appoint an enduring guardian, and have lost capacity, then a court or tribunal can <a href="https://www.tag.nsw.gov.au/guardianship/information-about-guardianship">appoint</a> that person a private guardian (usually a family member, close friend or unpaid carer).</p> <p>If no such person is available to act as private guardian, a public official may be appointed as public guardian.</p> <h2>Deal with your own feelings</h2> <p>Families often feel <a href="https://link.springer.com/article/10.1007/s12144-023-04538-9">guilt and grief</a> during the decision-making and transition process.</p> <p>Families need to act in the best interest of Mum or Dad, but also balance other caring responsibilities, financial priorities and their own wellbeing.<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/221210/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/lee-fay-low-98311"><em>Lee-Fay Low</em></a><em>, Professor in Ageing and Health, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p><em>Image credits: Getty Images </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

More than a third of people with dementia don’t know they have it – what to do if you suspect your partner has the condition

<p><em><a href="https://theconversation.com/profiles/kate-irving-1493654">Kate Irving</a>, <a href="https://theconversation.com/institutions/dublin-city-university-1528">Dublin City University</a></em></p> <p>Around <a href="https://www.bbc.co.uk/news/uk-england-67613465">36% of people</a> in England with dementia are unaware they have the condition, according to a new report from the Dementia Commission.</p> <p><a href="https://chamberuk.com/wp-content/uploads/2023/12/231127-Dementia-Commission-Report-Embargoed.pdf">The report</a> suggests things health and care professionals can do to improve spotting early signs of dementia. But what can you do if you think your partner has the condition? And how can you broach the topic with them?</p> <p>If you are worried about your partner having dementia, here are some useful things to know.</p> <p>Dementia is a term for a range of diseases (for example, Alzheimer’s) which develop over time (months and years) and cause problems with memory and reasoning, communication, changes in personality and a reduction in a person’s ability to carry out daily activities, such as shopping, washing, paying bills or cooking.</p> <p>Dementia can present very differently in each person, so it’s about knowing what’s normal for your loved one. A person who has always been conscientious and organised starting to unravel is very different from a scatterbrained person just being slightly more scatterbrained.</p> <p>Grief and stress can affect memory yet not be the start of dementia. But they can also mask the start of dementia: we call this “diagnostic over-shadowing”.</p> <p>There are also age-related changes to cognition. For example, we take longer to learn when we get older. But a one-off event – no matter how dramatic – is not necessarily dementia. It’s about looking for a pattern of decline.</p> <p>If you see these changes happen in a short space of time (weeks or days) it is unlikely to be dementia and could be something more serious. This requires urgent investigation by a doctor.</p> <h2>Greatest fear</h2> <p>Dementia is one of the greatest fears of our age. The horror of perceived loss of self can cause people to avoid discussing the issue, discussing it in an unhelpful way (such as criticising or inadvertently humiliating) or discussing it with other relatives, but not the person they are noticing changes in.</p> <p>Over time, this can cause a lack of trust to develop. Discussing memory problems openly with the person at the point of a memory failure or if they raise the concern is best. Of course, it takes courage and makes us face our own vulnerability.</p> <p>Sometimes the person will be in denial or lack insight into the memory problems (this can be a symptom of dementia, but isn’t always). If someone raises a concern about their memory issues, I would urge you not to minimise this, as it probably took courage to admit their concerns.</p> <p>I heard a relative say to my mother: “Oh, you left the pot on the stove. I lost the car in the multistory the other day.” My mother had dementia – the relative did not.</p> <p>If they are adamant that they do not have concerns, this is harder to deal with. One approach is to say: “I know you are not concerned, but I am concerned and I wonder if you would see a doctor to ease my worries?”</p> <p>Also explaining that memory problems can at least to some extent have reversible causes means a visit to the doctor to at least rule these out is an important step. It may also be encouraging to say to the person: “If there is something with your memory that will get worse over time, would you want to know?” (Most people <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2408568/">answer yes</a> to this).</p> <h2>Seeing a GP</h2> <p>If your partner agrees to visit a GP, it is helpful to prepare by filling in a diary for a week with the kind of memory (or other) problems experienced, what was happening at the time and the effect of the memory failure. This can be shared with a GP to help them to understand the issues.</p> <p>When people hear even the suggestion of the word dementia, they are faced with the uncertainties of what will become of them, of what they will lose, what they can keep up and where they will end up. These uncertainties are often shared with family members. But research shows that positive aspects of timely diagnosis <a href="https://www.scie.org.uk/dementia/symptoms/diagnosis/early-diagnosis.asp">outweigh fears</a> over time.</p> <p>At the same time, there are often ongoing stresses to do with memory impairments or confusion. With these stresses, everyday life can be troublesome, family relationships can suffer, and people can find it difficult to be supportive of each other.</p> <p>Being honest and open is the best policy. Stating that we are in this together, I want to help, let’s meet whatever happens head on, can help. If a person becomes resistant, it may be there is another family member who might better assist the person.<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/219172/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/kate-irving-1493654"><em>Kate Irving</em></a><em>, Professor of Clinical Nursing, <a href="https://theconversation.com/institutions/dublin-city-university-1528">Dublin City University</a></em></p> <p><em>Image credits: Getty Images</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

“Do not panic”: Passenger trapped in plane bathroom for entire flight

<p dir="ltr">A passenger has received the ultimate downgrade on a plane after becoming trapped in the bathroom for an entire flight. </p> <p dir="ltr">The unnamed flyer was travelling from Mumbai to Bengaluru in India on budget airline SpiceJet, when his one-hour-and-45-minute night flight turned into a nightmare. </p> <p dir="ltr">Shortly after takeoff, the man went to use the lavatory and discovered he had become stuck in the bathroom when he attempted to leave.</p> <p dir="ltr">The crew and other passengers desperately attempted to free the flyer from the unfortunate position, but to no avail. </p> <p dir="ltr">As a result, he was relegated to the toilet in the sky for nearly the entire flight.</p> <p dir="ltr">In an attempt to calm the passenger during his in-flight solitary confinement, crew members slid a note under the door to reassure the man.</p> <p dir="ltr">“Sir we tried our best to open the door, however, we could not,” the letter read. </p> <p dir="ltr">“Do not panic. We are landing in a few minutes, so please close the commode lid and sit on it and secure yourself. As soon as the main door is open, an engineer will come. Do not panic.”</p> <p dir="ltr">After landing, two engineers boarded the aircraft and broke open the door, rescuing the captive who later received “immediate medical support.”</p> <p dir="ltr">The airline has since issued the flyer a full reimbursement and shared an apology for the unique flying experience. </p> <p dir="ltr">“SpiceJet regrets and apologises for the inconvenience caused to the passenger,” they said. “The passenger is being provided a full refund.”</p> <p dir="ltr"><em>Image credits: Getty Images / X (Twitter)</em></p>

"You don’t know why they’re filming or what they’ll do with it": flight attendants on being unwilling stars of viral videos

<p><em><a href="https://theconversation.com/profiles/liz-simmons-1376255">Liz Simmons</a>, <a href="https://theconversation.com/institutions/griffith-university-828">Griffith University</a>; <a href="https://theconversation.com/profiles/gui-lohmann-1476773">Gui Lohmann</a>, <a href="https://theconversation.com/institutions/griffith-university-828">Griffith University</a>, and <a href="https://theconversation.com/profiles/rawan-nimri-1482182">Rawan Nimri</a>, <a href="https://theconversation.com/institutions/griffith-university-828">Griffith University</a></em></p> <p>As any frequent social media user knows, airline passengers often record and post in-flight incidents – from frightening turbulence to unruly members of the public.</p> <p>Often, these viral videos feature flight attendants just trying to do their duties, while being filmed without their consent.</p> <p>These videos usually portray flight attendants either as heroes effortlessly managing difficult passengers or “villains” accused of being rude and unprofessional. Either way, the trend is emerging as an industrial issue, with unions arcing up about it and airlines bringing in new rules aimed at curbing the practice.</p> <h2>Unkind comments about appearance and age</h2> <p>Going to work knowing that at any moment you may become the unwilling star of a viral video can exact a considerable toll on the wellbeing of flight attendants.</p> <p>I (Liz Simmons) speak daily with flight attendants in Australia and abroad as part of my PhD research. From these discussions, I’ve heard from attendants who worry often about discovering videos of themselves featuring unkind comments about their appearance, age or employer.</p> <p>One flight attendant, Kate*, described the disconcerting feeling of someone aiming a smartphone camera at her while she was simply trying to do her job, saying: "You don’t know why they’re filming or what they’ll do with it."</p> <p>Marie spoke of being featured in a TikTok video during a safety demonstration, with viewers making fun of her appearance.</p> <p>Charlotte, after refusing to serve more alcohol to an intoxicated passenger, had a camera thrust in her face, accompanied by threats to her job.</p> <p>Mark told of how uncomfortable he felt having to ask a passenger to stop taking photos of the crew during service.</p> <p>These personal accounts illustrate the <a href="https://www.news.com.au/travel/travel-updates/health-safety/flight-attendant-reveals-creepy-passenger-behaviour/news-story/3b2b1ad25f758e24ef37b74794684ea6">distress</a> flight attendants can experience when being filmed or photographed without their knowledge.</p> <h2>A broader industrial issue</h2> <p>This issue is drawing the attention of policymakers, airlines and the unions that represent flight attendants.</p> <p>Japan recently introduced <a href="https://japannews.yomiuri.co.jp/society/crime-courts/20230408-102309/">laws</a> aimed at curbing sneak photography in a range of settings, which may be used to prevent passengers voyeuristically filming flight attendants. <a href="https://mondortiz.com/japan-flight-attendants-call-for-action-versus-stolen-photo-taking/">Research</a> by Japan’s aviation workers union found that about 70% of the 1,573 flight attendants surveyed believed they’d had their pictures taken surreptitiously while they were working.</p> <p>Passengers have been arrested in <a href="https://www.jpost.com/israel-news/crime-in-israel/article-748799">Turkey</a> and <a href="https://www.dailymail.co.uk/travel/travel_news/article-3554181/IndiGo-passenger-arrested-recording-video-flight-attendants.html">India</a> after unauthorised filming.</p> <p>And flight attendant unions in <a href="https://www.japantimes.co.jp/news/2023/03/09/national/crime-legal/flight-attendant-photo/">Japan</a>, <a href="https://www.thestandard.com.hk/breaking-news/section/4/204104/Union-says-flight-attendants-can-ask-passengers-to-delete-photos-and-videos-taken-without-consent">Hong Kong</a> and <a href="https://www.stuff.co.nz/travel/news/300750512/why-you-shouldnt-film-your-cabin-crew">Australia</a> have voiced concerns about the issue.</p> <p>Of course, videos can occasionally play a crucial role in understanding what transpired during an <a href="https://www.nbcnews.com/news/us-news/passenger-assault-attendant-detained-fbi-american-airlines-mexico-cabo-rcna48884">in-flight incident</a>, and flight attendants themselves can also be found on social media sharing their stories, consenting to the video. But many videos still feature airline staff simply going about their job (while being filmed, without their consent).</p> <h2>Unclear rules</h2> <p>News <a href="https://www.smh.com.au/traveller/reviews-and-advice/why-you-shouldnt-film-your-cabin-crew-20221122-h2813d.html">reports</a> suggest staff aboard Dutch carrier KLM “now commonly make an announcement during the safety briefing asking passengers not to take photos of any crew members.”</p> <p>The <a href="https://www.klm.com.au/information/legal/conditions-carriage">rules</a> on the KLM website are less clear, saying only that, "Recording videos and/or taking photographs other than personal videos and photographs is prohibited on board the aircraft."</p> <p>Virgin Australia’s rules state anyone travelling on their planes must "use cameras or photographic devices (including mobile phones) for personal use only. You must comply with the directions of flight crew when using cameras or photographic devices while on board.</p> <p>In November 2023, Qantas introduced new <a href="https://www.qantas.com/au/en/book-a-trip/flights/conditions-of-carriage.html#conduct-during-flight">rules</a> requiring passengers to "seek consent before filming or photographing Qantas Group staff, contractors or other customers."</p> <p>This is a start. For most airlines, however, there is a notable absence of clear guidelines against recording and publishing footage of flight attendants in their workplace. The existing rules are often buried in the fine print of terms and conditions, which few passengers take the time to read. This underscores the necessity for airlines to reconsider how these restrictions are communicated to passengers.</p> <p>Looking ahead, it may be timely for more airlines to establish clearer rules on filming cabin crew while they work. There should be an acknowledgement that unsolicited filming is frequently unfair, invasive and distressing. Developing a framework to enforce these provisions and enhancing communication about these rules would help inform passengers about how to respect the privacy and comfort of flight attendants in their workplace.</p> <p><em>* All names have been changed to protect identities.</em><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/217089/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/liz-simmons-1376255">Liz Simmons</a>, PhD Candidate, <a href="https://theconversation.com/institutions/griffith-university-828">Griffith University</a>; <a href="https://theconversation.com/profiles/gui-lohmann-1476773">Gui Lohmann</a>, Professor in Air Transport and Tourism Management, <a href="https://theconversation.com/institutions/griffith-university-828">Griffith University</a>, and <a href="https://theconversation.com/profiles/rawan-nimri-1482182">Rawan Nimri</a>, Lecturer in Tourism and Hospitality, <a href="https://theconversation.com/institutions/griffith-university-828">Griffith University</a></em></p> <p><em>Image credits: </em><em>Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Why are my muscles sore after exercise? Hint: it’s nothing to do with lactic acid

The truth is far more interesting, but also a bit more complex.</p> <h2>It’s not lactic acid</h2> <p>We’ve known for decades that lactic acid has <a href="https://pubmed.ncbi.nlm.nih.gov/27409551/">nothing to do with</a> muscle soreness after exercise.</p> <p>In fact, as one of us (Robert Andrew Robergs) has long <a href="https://journals.physiology.org/doi/full/10.1152/ajpregu.00114.2004">argued</a>, cells produce lactate, not lactic acid. This process actually <a href="https://journals.physiology.org/doi/full/10.1152/physiol.00033.2017">opposes</a> not causes the build-up of acid in the muscles and bloodstream.</p> <p>Unfortunately, historical inertia means people still use the term “lactic acid” in relation to exercise.</p> <p>Lactate <a href="https://www.science.org/doi/10.1126/science.1101141">doesn’t cause major problems</a> for the muscles you use when you exercise.

And being less wrecked by exercise makes it more enjoyable and more easy to stick to a routine or habit.</p> <p>Finally, remove “lactic acid” from your exercise vocabulary. Its supposed role in muscle soreness is a myth that’s hung around far too long already.<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/214638/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/robert-andrew-robergs-435390"><em>Robert Andrew Robergs</em></a><em>, Associate Professor - Exercise Physiology, <a href="https://theconversation.com/institutions/queensland-university-of-technology-847">Queensland University of Technology</a> and <a href="https://theconversation.com/profiles/samuel-l-torrens-1476404">Samuel L.

"Do you hear it?": Worldwide hum global mystery baffles scientists

<p>A perplexing phenomenon known as "The Worldwide Hum" has been capturing the attention of scientists and citizens alike, as an unusual low-frequency noise continues to puzzle experts.</p> <p>This mysterious hum, first recorded in 2012, has been reported by thousands of people worldwide, sparking investigations, online discussions and even <a href="https://www.thehum.info/" target="_blank" rel="noopener">the creation of an interactive map</a> documenting instances of the enigmatic sound. As researchers strive to unravel the mystery, individuals share their experiences, raising questions about its origin and effects.</p> <p>Described as a low rumbling or droning sound, "the hum" is often likened to the idling of a car or truck engine. What makes this phenomenon particularly intriguing is that it is not universally heard, with reports of the hum being exclusive to certain individuals.</p> <p>Some claim it is more pronounced at night than during the day, and louder indoors than outdoors. One Reddit user even compared it to the low-frequency vibrations felt when a passenger jet flies overhead.</p> <p>Since its first documentation, more than 6,500 instances of the hum have been reported globally, with new cases continually emerging. The interactive user-generated World Hum Map and Database Project <span style="font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen, Ubuntu, Cantarell, 'Open Sans', 'Helvetica Neue', sans-serif;">captures the experiences of those who have encountered the sound, providing a comprehensive overview of its widespread occurrence. In some regions, authorities such as the Environment Protection Authority (EPA) have conducted investigations, as was the case in the NSW Waverley Council ten years ago. Despite these efforts, the source of the hum remains elusive.</span></p> <p>Individuals affected by the mysterious noise often find solace in online communities, where they share their experiences and discuss possible explanations. Some describe feeling as though they are "going insane", and say that the psychological impact of the persistent hum is actually very severe.</p> <p>Facebook support groups have become a platform for individuals to connect, share anecdotes and speculate about the origin of the sound. Theories range from the mundane – such as the use of headphones causing collective tinnitus – to more complex environmental factors.</p> <p>While tinnitus, a symptom of auditory system issues, has been proposed as a potential explanation, it does not account for the collective experience of the hum. Various theories, including industrial plants, ocean waves, lightning strikes and the proliferation of mobile phone towers, have been suggested over the years. However, none of these explanations have gained widespread acceptance or provided a conclusive answer.</p> <p>Dr Glen MacPherson, who initiated the World Hum Map and Database Project, experienced the hum firsthand on Canada's Sunshine Coast. Having debunked the idea of "hum hotspots", Dr MacPherson theorises that the hum may be a subjective phenomenon, akin to tinnitus, originating from within the individual rather than an external source. His 11 years of research highlight the complexity of the mystery, challenging initial assumptions and pointing towards the need for further investigation.</p> <p>As "The Worldwide Hum" continues to captivate the curiosity of scientists and citizens worldwide, the quest for understanding remains elusive. While theories abound, the true origin of the hum remains unknown, leaving both experts and individuals alike intrigued by a phenomenon that transcends geographic boundaries and defies conventional explanations.</p> <p><em>Image: Getty</em></p>
