Taking more than 5 pills a day? ‘Deprescribing’ can prevent harm – especially for older people

As societies continue to grow older, one pressing concern is the use of multiple medications, a phenomenon known as <a href="https://www.who.int/docs/default-source/patient-safety/who-uhc-sds-2019-11-eng.pdf">polypharmacy</a>.</p> <p>About <a href="https://onlinelibrary.wiley.com/doi/full/10.5694/mja2.50244">1 million older Australians</a> experience polypharmacy and this group is increasing. They may wake up in the morning and pop a pill for their heart, then another one or two to control blood pressure, a couple more if they have diabetes, a vitamin pill and maybe one for joint pain.</p> <p>Polypharmacy is usually <a href="https://www.safetyandquality.gov.au/sites/default/files/2021-04/fourth_atlas_2021_-_6.1_polypharmacy_75_years_and_over.pdf">defined</a> as taking five or more different medications daily. In aged care homes, <a href="https://doi.org/10.1016/j.archger.2022.104849">90% of residents</a> take at least five regular medications every single day. That can put their health at risk with increased costs for them and the health system.</p> <h2>Adding up over time</h2> <p>As people age, the effects of medications can change. Some medications, which were once beneficial, might start to do more harm than good or might not be needed anymore. About <a href="https://www.psa.org.au/wp-content/uploads/2020/02/Medicine-Safety-Aged-Care-WEB-RES1.pdf">half of older Australians</a> are taking a medication where the likely harms outweigh the potential benefits.</p> <p>While polypharmacy is sometimes necessary and helpful in managing multiple health conditions, it can lead to unintended consequences.</p> <p><a href="https://www.nps.org.au/living-with-multiple-medicines/costs">Prescription costs</a> can quickly add up. Taking multiple medications can be difficult to manage particularly when there are specific instructions to crush them or take them with food, or when extra monitoring is needed. There is also a risk of <a href="https://www.nps.org.au/consumers/understanding-drug-interactions">drug interactions</a>.</p> <p>Medications bought “over the counter” without a prescription, such as vitamins, herbal medications or pain relievers, can also cause <a href="https://onlinelibrary.wiley.com/doi/abs/10.5694/mja11.10698">problems</a>. Some people might take an over-the-counter medication each day due to previous advice, but they might not need it anymore. Just like prescription medications, over-the-counter medications add to the overall burden and cost of polypharmacy as well as drug interactions and side effects.</p> <p>Unfortunately, the more medications you take, the more likely you are to have <a href="https://www.nps.org.au/consumers/managing-your-medicines#risks-of-taking-multiple-medicines">problems with your medications</a>, a reduced quality of life and increased risk of falls, hospitalisation and death. Each year, <a href="https://www.psa.org.au/wp-content/uploads/2019/01/PSA-Medicine-Safety-Report.pdf">250,000 Australians</a> are admitted to hospital due to medication-related harms, many of which are preventable. For example, use of multiple medications like sleeping pills, strong pain relievers and some blood pressure medications can cause drowsiness and dizziness, potentially resulting in a <a href="https://betterhealthwhileaging.net/preventing-falls-10-types-of-medications-to-review/">fall</a> and broken bones.</p> <h2>Prescribing and deprescribing are both important</h2> <p>Ensuring safe and effective use of medications involves both prescribing, and <a href="https://www.racgp.org.au/clinical-resources/clinical-guidelines/key-racgp-guidelines/view-all-racgp-guidelines/silver-book/part-a/deprescribing">deprescribing</a> them.</p> <p><a href="https://www.australiandeprescribingnetwork.com.au/474-2/">Deprescribing</a> is a process of stopping (or reducing the dose of) medications that are no longer required, or for which the risk of harm outweighs the benefits for the person taking them.</p> <p>The process involves reviewing all the medications a person takes with a health-care professional to identify medications that should be stopped.</p> <p>Think of deprescribing as spring cleaning your medicine cabinet. Just like how you tidy up your house and get rid of objects that are causing clutter without being useful, deprescribing tidies up your medication list to keep only the ones truly required.</p> <h2>But care is needed</h2> <p>The process of deprescribing requires close monitoring and, for many medications, slow reductions in dose (tapering).</p> <p>This helps the body adjust gradually and can prevent sudden, unpleasant changes. Deprescribing is often done on a trial basis and medication can be restarted if symptoms come back. Alternatively, a safer medication, or non-drug treatment may be started in its place.</p> <p>Studies show deprescribing is a safe process when managed by a health-care professional, both for people living at <a href="https://link.springer.com/article/10.1007/s11606-020-06089-2">home</a> and those in <a href="https://doi.org/10.1016/j.jamda.2018.10.026">residential aged care</a>. You should always talk with your care team before stopping any medications.</p> <p>Deprescribing needs to be a team effort involving the person, their health-care team and possibly family or other carers. Shared decision-making throughout the process empowers the person taking medications to have a say in their health care. The team can work together to clarify treatment goals and decide which medications are still serving the person well and which can be safely discontinued.</p> <p>If you or a loved one take multiple medications you might be eligible for a free visit from a pharmacist (<a href="https://www.nps.org.au/assets/NPS/pdf/NPSMW2390_Anticholinergics_HMR_Factsheet.pdf">a Home Medicines Review</a>) to help you get the best out of your medications.</p> <h2>What’s next?</h2> <p>Health care has traditionally focused on prescribing medications, with little focus on when to stop them. Deprescribing is not happening as often as it should. <a href="https://www.australiandeprescribingnetwork.com.au/">Researchers</a> are working hard to develop tools, resources and service models to support deprescribing in the community.</p> <p>Health-care professionals may think older adults are not open to deprescribing, but about <a href="https://academic.oup.com/biomedgerontology/article/77/5/1020/6352400">eight out of ten people</a> are willing to stop one or more of their medications. That said, of course some people may have concerns. If you have been taking a medication for a long time, you might wonder why you should stop or whether your health could get worse if you do. These are important questions to ask a doctor or pharmacist.</p> <p>We need more <a href="https://shpa.org.au/news-advocacy/MedsAware">public awareness</a> about polypharmacy and deprescribing to turn the tide of increasing medication use and related harms. <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/211424/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/emily-reeve-1461339">Emily Reeve</a>, Senior Research Fellow in the Centre for Medicine Use and Safety , <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a>; <a href="https://theconversation.com/profiles/jacinta-l-johnson-1441348">Jacinta L Johnson</a>, Senior Lecturer in Pharmacy Practice, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a>; <a href="https://theconversation.com/profiles/janet-sluggett-146318">Janet Sluggett</a>, Enterprise Fellow, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a>, and <a href="https://theconversation.com/profiles/kate-ohara-1462183">Kate O'Hara</a>, PhD student, Clinical Pharmacology and Toxicology, <a href="https://theconversation.com/institutions/university-of-newcastle-1060">University of Newcastle</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.

‘Psychological debriefing’ right after an accident or trauma can do more harm than good – here’s why

<p><em><a href="https://theconversation.com/profiles/richard-bryant-161">Richard Bryant</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a></em></p> <p>The recent <a href="https://www.abc.net.au/news/2023-06-18/hunter-valley-wedding-bus-crash-survivors-remain-in-hospital/102487630">tragic bus accident</a> in the New South Wales Hunter Valley has again raised the issue of how we address the potential psychological effects of traumatic events.</p> <p>It is interesting we revisit the same debate after each disaster, and few lessons have apparently been learned after decades of research. After the Hunter Valley accident, immediate psychological counselling was <a href="https://www.theguardian.com/australia-news/2023/jun/15/hunter-valley-bus-crash-company-issued-with-defect-notices-after-police-raid">offered to those affected</a>.</p> <p>While we can’t say what form of counselling was offered, the traditional approach is known as “<a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1118833/">psychological debriefing</a>”. This typically involves counsellors providing trauma survivors with a single counselling intervention within days of the event.</p> <p>Although the content of the intervention can vary, it usually involves education about stress reactions, encouragement to disclose their memories of the experience, some basic stress-coping strategies and possibly referral information.</p> <p>But the evidence shows this approach, however well-meaning, may not help – or worse, do harm.</p> <h2>The belief that feelings must be shared</h2> <p>The encouragement of people to discuss their emotional reactions to a trauma is the result of a long-held notion in psychology (dating back to the classic writings of Sigmund Freud) that disclosure of one’s emotions is invariably beneficial for one’s mental health.</p> <p>Emanating from this perspective, the impetus for psychological debriefing has traditionally been rooted in the notion trauma survivors are vulnerable to psychological disorders, such as post-traumatic stress disorder (PTSD), if they do not “talk through their trauma” by receiving this very <a href="https://journals.sagepub.com/doi/full/10.1177/1529100610387086">early intervention</a>.</p> <p>The scenario of trauma counsellors appearing in the acute aftermath of traumatic events has been commonplace for decades in Australia and elsewhere.</p> <p>Following the 9/11 terrorist attacks in New York City in 2001, up to 9,000 counsellors were mobilised and more than <a href="https://www.nytimes.com/2002/07/22/nyregion/finding-cure-for-hearts-broken-sept-11-is-as-difficult-as-explaining-the-cost.html">US$200 million</a> was projected to meet a surge in mental health needs. But fewer people than expected sought help under this program and $90 million remained <a href="https://theconversation.com/9-11-anniversary-a-watershed-for-psychological-response-to-disasters-2975">unspent</a>.</p> <h2>What do we know about psychological reactions to disasters?</h2> <p>The overwhelming evidence indicates the majority of people will <a href="http://www.psychologicalscience.org/publications/journals/pspi/weighing-the-costs-of-disaster.html">adapt</a> to traumatic events without any psychological intervention.</p> <p>Long-term studies indicate approximately 75% of trauma survivors will not experience any long-term distress. Others will experience short-term distress and subsequently adapt. A minority (usually about 10%) will <a href="https://journals.sagepub.com/doi/10.1177/1529100610387086">experience chronic psychological problems</a>.</p> <p>This last group are the ones who require care and attention to reduce their mental health problems. Experts now agree other trauma survivors can rely on their own <a href="https://www.rcpsych.ac.uk/mental-health/problems-disorders/coping-after-a-traumatic-event">coping resources and social networks</a> to adapt to their traumatic experience.</p> <p>The finding across many studies that most people adapt to traumatic experiences <a href="https://journals.sagepub.com/doi/10.1177/1529100610387086">without formal mental health interventions</a> has been a major impetus for questioning the value of psychological debriefing in the immediate aftermath of disasters.</p> <p>In short, the evidence tells us universal interventions – such as psychological debriefing for everyone involved in a disaster – that attempt to prevent PTSD and other psychological disorders in trauma survivors are not indicated. These attempts <a href="https://journals.sagepub.com/doi/10.1177/1529100610387086#bibr448-1529100610387086">do not prevent</a> the disorder they are targeting.</p> <h2>Not a new conclusion</h2> <p>In the aftermath of the 2004 Indian Ocean earthquake and tsunami, the World Health Organization listed a warning (which <a href="https://www.who.int/teams/mental-health-and-substance-use/treatment-care/mental-health-gap-action-programme/evidence-centre/other-significant-emotional-and-medical-unexplained-somatic-complaints/psychological-debriefing-in-people-exposed-to-a-recent-traumatic-event">still stands</a>) that people should not be given single-session psychological debriefing because it is <a href="https://journals.sagepub.com/doi/10.1177/1529100610387086#bibr448-1529100610387086">not supported</a> by evidence.</p> <p>Worse than merely being ineffective, debriefing can be <a href="https://www.jenonline.org/article/S0099-1767(19)30453-2/fulltext#:%7E:text=It%20is%20for%20these%20reasons,%2C%20anxiety%20or%20depressive%20symptoms.%E2%80%9D">harmful for some people</a> and may increase the risk of PTSD.</p> <p>The group of trauma survivors that are most vulnerable to the toxic effects of debriefing are those who are more distressed in the acute phase right after the trauma. This group of people have worse mental health outcomes if they are provided with early debriefing.</p> <p>This may be because their trauma memories are over-consolidated as a result of the emotional disclosure so shortly after the event, when <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3181836/#:%7E:text=Brain%20areas%20implicated%20in%20the,norepinephrine%20responses%20to%20subsequent%20stressors.">stress hormones</a> are still highly active.</p> <p>In normal clinical practice a person would be assessed in terms of their suitability for any psychological intervention. But in the case of universal psychological debriefing there is no prior assessment. Therefore, there’s no assessment of the risks the intervention may pose for the person.</p> <h2>Replacing debriefing</h2> <p>Most international bodies have shifted away from psychological debriefing. Early intervention might now be offered as “<a href="https://www.sciencedirect.com/topics/medicine-and-dentistry/psychological-first-aid">psychological first aid</a>”.</p> <p>This newer approach is meant to provide <a href="https://www.who.int/publications/i/item/9789241548205">fundamental support and coping strategies</a> to help the person manage the immediate aftermath of adversity. One of the most important differences between psychological first aid and psychological debriefing is that it does not encourage people to disclose their emotional responses to the trauma.</p> <p>But despite the increasing popularity of psychological first aid, it is difficult to assess its effectiveness as it does not explicitly aim to prevent a disorder, such as PTSD.</p> <h2>Wanting to help</h2> <p>So if there is so much evidence, why do we keep having this debate about the optimal way to assist psychological adaptation after disasters? Perhaps it’s because it’s human nature to want to help.</p> <p>The evidence suggests we should monitor the most vulnerable people and target resources towards them when they need it – usually some weeks or months later when the dust of the trauma has settled. Counsellors might want to promote their activities in the acute phase after disasters, but it may not be in the best interest of the trauma survivors.</p> <p>In short, we need to develop better strategies to ensure we are meeting the needs of the survivors, rather than the counsellors.</p> <hr /> <p><em>If this article has raised issues for you, or if you’re concerned about someone you know, call Lifeline on 13 11 14.<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/208139/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></em></p> <p><em><a href="https://theconversation.com/profiles/richard-bryant-161">Richard Bryant</a>, Professor &amp; Director of Traumatic Stress Clinic, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a></em></p> <p><em>Image credits: Getty Images </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Gastro or endometriosis? How your GP discusses uncertainty can harm your health

<p>You wake with stomach pain that worsens during the day and decide to see your doctor. You describe your symptoms and your doctor examines you. Then the doctor says, “From what I hear, I think you could just have a stomach bug. Rest and come back in three days.”</p> <p>This might be a less definitive answer than you’re after. But doctors can’t always be sure of a diagnosis straight away. As <a href="https://link.springer.com/article/10.1007/s11606-022-07768-y">my review</a> shows, doctors use various ways of communicating such uncertainty.</p> <p>Sometimes there is a mismatch between what doctors say when they’re uncertain and how patients interpret what they say, which can have harmful consequences.</p> <h2>Why does uncertainty matter?</h2> <p>Doctors <a href="https://link.springer.com/article/10.1007/s11606-017-4164-1">cannot always explain</a> what your health problem is or what caused it. Such diagnostic uncertainty is a normal and <a href="https://doi.org/10.1001/jama.2022.2141">ever-present part</a> of the processes leading to a diagnosis. For instance, doctors often have to rule out other possible diagnoses before settling on one that’s most likely.</p> <p>While doctors ultimately get the diagnosis right <a href="http://dx.doi.org/10.1136/bmjqs-2012-001615">in 85-90%</a> of cases, diagnostic uncertainty can lead to diagnostic delays and is a huge contributor to harmful or even deadly misdiagnoses.</p> <p>Every year, <a href="https://www.mja.com.au/system/files/issues/213_07/mja250771.pdf">an estimated</a> 21,000 people are seriously harmed and 2,000-4,000 people die in Australia because their diagnosis was delayed, missed or wrong. That could be because the wrong treatment was provided and caused harm, or the right treatment was not started or given after the condition had already considerably progressed. More than <a href="https://www.mja.com.au/system/files/issues/213_07/mja250771.pdf">80% of diagnostic errors</a> could have been prevented.</p> <p>Three medical conditions – infections, cancer and major vascular events (such as strokes or heart attacks) – are the so-called “<a href="https://doi.org/10.1515/dx-2019-0019">Big Three</a>” and cause devastating harm if misdiagnosed.</p> <p>In my review, the top three symptoms – fever, chest pain and abdominal pain – were most often linked to diagnostic uncertainty. In other words, most of us will have had at least one of these very common symptoms and thus been at risk of uncertainty and misdiagnosis.</p> <p>Some groups are less likely to be diagnosed correctly or without inappropriate delay than others, leading to <a href="https://doi.org/10.1001/jama.2022.7252">diagnostic inequities</a>. This may be the case for <a href="https://www.liebertpub.com/doi/10.1089/whr.2022.0052">women</a>, and other groups marginalised because of their <a href="https://onlinelibrary.wiley.com/doi/10.1111/acem.14142">race or ethnicity</a>, <a href="https://doi.org/10.1016/j.socscimed.2020.113609">sexual orientation or gender identity</a>, or <a href="https://doi.org/10.1001/jama.2022.7252">language proficiency</a>.</p> <h2>How often do you hear ‘I don’t know’?</h2> <p>My research showed doctors often make diagnostic uncertainty clear to patients by using explicit phrases such as: “I don’t know.”</p> <p>But doctors can also keep quiet about any uncertainty or signal they’re uncertain in more subtle ways.</p> <p>When doctors believe patients prefer clear answers, they may only share the most likely diagnosis. They say: “It’s a stomach bug” but leave out, “it could also be constipation, appendicitis or endometriosis”. </p> <p>Patients leave thinking the doctor is confident about the (potentially correct or incorrect) diagnosis, and remain uninformed about possible other causes. </p> <p>This can be especially frustrating for patients with chronic symptoms, where such knowledge gaps can lead to lengthy diagnostic delays, as reported for <a href="https://doi.org/10.1016/j.ajog.2018.12.039">endometriosis</a>.</p> <p>Subtle ways of communicating uncertainty include hedging with certain words (could, maybe) or using introductory phrases (my guess, I think). Other implicit ways are consulting a colleague or the Internet, or making follow-up appointments.</p> <p>If patients hear “I think this could be a stomach bug” they may think there’s some uncertainty. But when they hear “come back in three days” the uncertainty may not be so obvious.</p> <p>Sharing uncertainty implicitly (rather than more directly), can leave patients unaware of new symptoms signalling a dangerous change in their condition.</p> <h2>What can you do about it?</h2> <p><strong>1. Ask about uncertainty</strong></p> <p>Ask your doctor to share any <a href="http://dx.doi.org/10.1515/dx-2021-0086">uncertainty and other diagnostic reasoning</a>. Ask about alternative diagnoses they’re considering. If you’re armed with such knowledge, you can better engage in your care, for example asking for a review when your symptoms worsen.</p> <p><strong>2. Manage expectations together</strong></p> <p>Making a diagnosis can be an evolving process rather than a single event. So ask your doctor to outline the diagnostic process to help manage any <a href="http://dx.doi.org/10.1136/ebm.14.3.66">mismatched expectations</a> about how long it might take, or what might be involved, to reach a diagnosis. Some conditions need time for symptoms to evolve, or further tests to exclude or confirm.</p> <p><strong>3. Book a long appointment</strong></p> <p>When we feel sick, we might get anxious or find we experience heightened levels of fear and other emotions. When we hear our doctor isn’t certain about what’s causing our symptoms, we may get even more anxious or fearful.</p> <p>In these cases, it can take time to discuss uncertainty and to learn about our options. So book a long appointment to give your doctor enough time to explain and for you to ask questions. If you feel you’d like some support, you can ask a close friend or family member to attend the appointment with you and to take notes for you.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://theconversation.com/gastro-or-endometriosis-how-your-gp-discusses-uncertainty-can-harm-your-health-196943" target="_blank" rel="noopener">The Conversation</a>. </em></p>

So we cannot jump to the conclusion COVID infections have given rise to these and other viral infections.</p> <p>But evidence is building of the negative impact of COVID on a healthy individual’s immune system, several weeks after symptoms have subsided.</p> <h2>What happens when you catch a virus?</h2> <p>There are three possible outcomes after a viral infection:</p> <p>1) your immune system clears the infection and you recover (for instance, with <a href="https://www.healthychildren.org/English/health-issues/conditions/ear-nose-throat/Pages/Rhinovirus-Infections.aspx" target="_blank" rel="noopener">rhinovirus</a> which causes the common cold)</p> <p>2) your immune system fights the virus into “latency” and you recover with a virus dormant in our bodies (for instance, <a href="https://www.healthdirect.gov.au/chickenpox" target="_blank" rel="noopener">varicella zoster virus</a>, which causes chickenpox)</p> <p>3) your immune system fights, and despite best efforts the virus remains “chronic”, replicating at very low levels (this can occur for <a href="https://www.who.int/news-room/fact-sheets/detail/hepatitis-c" target="_blank" rel="noopener">hepatitis C virus</a>).</p> <p>Ideally we all want option 1, to clear the virus. In fact, most of us <a href="https://biosignaling.biomedcentral.com/articles/10.1186/s12964-022-00856-w" target="_blank" rel="noopener">clear SARS-CoV-2</a>, the virus that causes COVID. That’s through a complex process, using many different parts of our immune system.</p> <p>But international evidence suggests changes to our immune cells after SARS-CoV-2 infection may have other impacts. It may affect our ability to fight other viruses, as well as other pathogens, such as bacteria or fungi.</p> <h2>How much do we know?</h2> <p>An <a href="https://bmcmedicine.biomedcentral.com/articles/10.1186/s12916-021-02228-6" target="_blank" rel="noopener">Australian study</a> has found SARS-CoV-2 alters the balance of immune cells up to 24 weeks after clearing the infection.</p> <p>There were changes to the relative numbers and types of immune cells between people who had recovered from COVID compared with healthy people who had not been infected.</p> <p>This included changes to cells of the <a href="https://www.khanacademy.org/test-prep/mcat/organ-systems/the-immune-system/a/innate-immunity" target="_blank" rel="noopener">innate immune system</a> (which provides a non-specific immune response) and the <a href="https://www.ncbi.nlm.nih.gov/books/NBK21070/" target="_blank" rel="noopener">adaptive immune system</a> (a specific immune response, targeting a recognised foreign invader).</p> <p><a href="https://journals.plos.org/plospathogens/article?id=10.1371/journal.ppat.1009742" target="_blank" rel="noopener">Another study</a> focused specifically on <a href="https://www.immunology.org/public-information/bitesized-immunology/cells/dendritic-cells" target="_blank" rel="noopener">dendritic cells</a> – the immune cells that are often considered the body’s “first line of defence”.</p> <p>Researchers found fewer of these cells circulating after people recovered from COVID. The ones that remained were less able to activate white blood cells known as <a href="https://www.britannica.com/science/T-cell" target="_blank" rel="noopener">T-cells</a>, a critical step in activating anti-viral immunity.</p> <p>Other studies have found different impacts on T-cells, and other types of white blood cells known as <a href="https://askabiologist.asu.edu/b-cell" target="_blank" rel="noopener">B-cells</a> (cells involved in producing antibodies).</p> <p>After SARS-CoV-2 infection, one study <a href="https://doi.org/10.1172/JCI140491" target="_blank" rel="noopener">found evidence</a> many of these cells had been activated and “exhausted”. This suggests the cells are dysfunctional, and might not be able to adequately fight a subsequent infection. In other words, sustained activation of these immune cells after a SARS-CoV-2 infection may have an impact on other inflammatory diseases.</p> <p><a href="https://www.nature.com/articles/s41392-021-00749-3#citeas" target="_blank" rel="noopener">One study</a> found people who had recovered from COVID have changes in different types of B-cells. This included changes in the cells’ metabolism, which may impact how these cells function. Given B-cells are critical for producing antibodies, we’re not quite sure of the precise implications.</p> <p>Could this influence how our bodies produce antibodies against SARS-CoV-2 should we encounter it again? Or could this impact our ability to produce antibodies against pathogens more broadly – against other viruses, bacteria or fungi? The study did not say.</p> <h2>What impact will these changes have?</h2> <p>One of the main concerns is whether such changes may impact how the immune system responds to other infections, or whether these changes might worsen or cause other chronic conditions.</p> <p>So more work needs to be done to understand the long-term impact of SARS-CoV-2 infection on a person’s immune system.</p> <p>For instance, we still don’t know how long these changes to the immune system last, and if the immune system recovers. We also don’t know if SARS-CoV-2 triggers other chronic illnesses, such as <a href="https://www.healthdirect.gov.au/chronic-fatigue-syndrome-cfs-me" target="_blank" rel="noopener">chronic fatigue syndrome</a> (myalgic encephalomyelitis). Research into this is ongoing.</p> <p>What we do know is that having a healthy immune system and being vaccinated (when a vaccine has been developed) is critically important to have the best chance of fighting any infection.</p> <p><strong>This article originally appeared on <a href="https://theconversation.com/ive-had-covid-and-am-constantly-getting-colds-did-covid-harm-my-immune-system-am-i-now-at-risk-of-other-infectious-diseases-188899" target="_blank" rel="noopener">The Conversation</a>.</strong></p> <p><em>Image: Shutterstock</em></p>

Research shows it’s harmful to smack your child, so what should parents do instead?

<p>Today, if a parent smacks a child mid-tantrum in the supermarket, they are likely to get looks of disapproval from other shoppers. Smacking is not as socially acceptable as it used to be.</p> <p>Recent <a href="https://www.australianchildmaltreatmentstudy.org/the-prevalence-of-corporal-punishment-in-australia/" target="_blank" rel="noopener">research</a> shows only 15% of people aged 16-24 view physical discipline as necessary to properly raise children. This compares with 38% of people over 65.</p> <p>But it still happens – and it is very harmful to children. So we need to help parents find alternative methods of discipline.</p> <h2>It is more common than you might think</h2> <p>In 2017, the royal commission into child sexual abuse recommended a national study on how common child abuse is in Australia. Early findings <a href="https://www.australianchildmaltreatmentstudy.org/the-prevalence-of-corporal-punishment-in-australia/" target="_blank" rel="noopener">released last month</a> revealed 61% of those aged 16-24 said they were physically hit for discipline four or more times during their childhood.</p> <p>The research also found those who were hit had almost double the risk of depression and anxiety. This partly because those who had been smacked as a child may have also experienced other forms of mistreatment, such as harsh parental reactions, neglect or insufficient support.</p> <p>This fits with other research showing negative consequences if children are smacked or hit. A 2016 <a href="https://doi.org/10.1037/fam0000191" target="_blank" rel="noopener">review</a> of more than 70 international studies showed it was linked to reduced compliance with parents’ instructions over time, children having increased aggression and antisocial behaviour, mental health problems, and lower self-esteem.</p> <p>In adulthood, it is also linked to antisocial behaviour and being either a victim or perpetrator of intimate partner violence.</p> <h2>What does the law say?</h2> <p>Currently, the use of reasonable force for the purpose of discipline in the home remains lawful under <a href="https://aifs.gov.au/resources/resource-sheets/physical-punishment-legislation" target="_blank" rel="noopener">criminal law provisions</a> or common law principles made by courts. This is despite the fact it is illegal in most Australian states and territories in other settings such as schools, or between adults – where it is classed as assault.</p> <p>Many countries are changing their laws because they understand the harms and because it is a violation of <a href="https://www.ohchr.org/en/instruments-mechanisms/instruments/convention-rights-child" target="_blank" rel="noopener">children’s right</a> to live a life free from violence. Already, <a href="https://endcorporalpunishment.org/countdown/" target="_blank" rel="noopener">63 countries</a> have banned corporal punishment for children, including New Zealand, Sweden, Denmark, South Korea, Wales, Scotland, France and Japan.</p> <p>Parenting and family researchers have <a href="https://theconversation.com/lets-talk-about-making-smacking-children-illegal-16399" target="_blank" rel="noopener">long been pushing</a> for an end to corporal punishment <a href="https://www.3aw.com.au/growing-calls-to-make-smacking-children-illegal-as-england-considers-move/" target="_blank" rel="noopener">in Australia</a> as well.</p> <h2>Parenting is stressful</h2> <p>But this is not just about law reform. Raising kids can be challenging at the best of times. Kids misbehave or may not be in control of their emotions, and parents need to provide guidance to their children about what is appropriate behaviour.</p> <p>The good news is there are <a href="https://rdcu.be/cEvhu" target="_blank" rel="noopener">evidence-based alternatives</a> to smacking. These are <a href="https://www.bbc.com/future/article/20220607-what-should-you-do-when-a-child-misbehaves" target="_blank" rel="noopener">strategies</a> that aim to help children understand what behaviours are expected, teach them to work through their feelings and learn how to repair a situation or solve a problem.</p> <p>These approaches lead to much better outcomes for parents and children, including more realistic expectations on the part of the parent and a better relationship between the parent and child. They also improve a child’s well-being and mental health.</p> <h2>So, what are the alternatives to smacking?</h2> <p>Here are some approaches to consider with your child:</p> <p>1. Give clear and consistent limits about what you expect</p> <p>Children need to know how you want them to behave and for this to be clear. An example might be: “It’s not OK to hit your brother” or “You can’t take lollies off the supermarket shelves without asking me first.”</p> <p>2. Manage your own emotions</p> <p>Anger is contagious, so try not to lose your temper in front of your kids. Instead, pause before you react: take three deep breaths, have a cold drink of water, or step outside for a moment.</p> <p>3. Be a good role model for your child when you don’t manage situations well</p> <p>Parents need to show how they manage their own emotions - or make amends when they act in less-than-ideal ways. Parents should be brave enough to say “I’m sorry I got angry and shouted at you. I wasn’t very patient.”</p> <p>4. Explore the emotions behind behaviour</p> <p>Kids can be uncertain or confused by their emotions. So, try and help them understand their feelings. This could include saying something like “I can see you felt left out and jealous”.</p> <p>Also validate their emotions because this helps them feel accepted by you while learning to understand and manage their feelings. For example, say “It’s difficult when this happens”.</p> <p>When they are calmer, you could explore other feelings behind their actions.</p> <p>This is about separating feelings (jealousy, frustration) from behaviour (hitting). All feelings are okay, but not all behaviours.</p> <p>5. Resolve problems when everyone is calm</p> <p>No one can think, talk or listen properly if they are upset. Take time to do some breathing or something soothing with your child. Or perhaps they need a run around to release strong feelings.</p> <p>6. Support children to make amends</p> <p>When everyone is calmer, help them work out the solution or next step. This teaches them how to resolve situations, repair relationships and take responsibility for their behaviour. You might say something like, “It can be embarrassing saying sorry to someone you’ve been angry with. What do you think might help?”</p> <p>7. Explore natural consequences</p> <p>If something is broken, children might need to fix it, use pocket money to replace it, or explore what might make the situation better.</p> <p>Children need family rules about behaviour and it can be useful to discuss what should happen if these are broken.</p> <p>Getting discipline right is not easy as a parent, grandparent or carer. And this can be especially difficult if you were brought up with smacking (and have older relatives telling you it is “fine”).</p> <p>It’s worth remembering a <a href="https://www.childmatters.org.nz/downloads/CUB.pdf" target="_blank" rel="noopener">slogan</a> frequently used when we talk about an end to smacking: “children are unbeatable”. They deserve the same protection from violence as adults.</p> <p><strong>This article originally appeared in <a href="https://theconversation.com/research-shows-its-harmful-to-smack-your-child-so-what-should-parents-do-instead-186739" target="_blank" rel="noopener">The Conversation</a>. </strong></p> <p><em>Image: Shutterstock</em></p>

Why over-cleansing can do more harm than good

<p dir="ltr">As we all know, taking off your makeup and sunscreen at the end of the day is a vital part of anyone’s skincare routine.</p><p dir="ltr">This process not only helps you feel fresh and relaxed to get a good night’s sleep, but is also an essential step to remove dirt, oil and dead skin cells that can lead to skin feeling congested, breakouts and lasting dullness. </p><p dir="ltr">While most people opt for a makeup remover, such as wipes or cleansing serums, it turns out this process could be doing more harm than good - especially with ageing skin. </p><p dir="ltr">According to Dr Mike Bell, Head of Science and Research for the holy grail UK skincare brand No7, “The over-cleansing of skin - sometimes with harsh high surfactant foaming cleansers or high alcohol-based toners - can be as harmful as the over-use of make-up or ineffective removal of make-up.” </p><p dir="ltr">“The skin’s essential barrier can become stripped of important ceramides and lipids, leaving it more sensitive and vulnerable to the environment."</p><p dir="ltr">Dr Bell’s solution? Turn to a cleanser that gets the job done, without all the harsh ingredients. </p><p dir="ltr">"Effective removal does rely on cleansers with mild but effective surfactants as well as the right type of emollient oils that together can dissolve even the most stubborn make-up.”</p><p dir="ltr">“Branched ester emollients like isononyl isononanoate are particularly effective as is dimethicone for dissolving some of the higher waterproof make-ups. These are combined with olive oil-based emulsifiers to take your make-up off seamlessly without harming the skin," he says. </p><p dir="ltr">Luckily, No7 offers a huge range of cleansers for all skin types, with tested formulas that will help remove makeup with ease, and not damage your skin in the process. </p><p dir="ltr"><a href="https://www.priceline.com.au/no7-biodegradable-cleansing-wipes-30-wipes">No7 Biodegradable Cleansing Wipes</a> are a tested favourite, with the soft and gentle wipes helping to clear pores and banish all traces of impurity with ease. </p><p><img src="https://oversixtydev.blob.core.windows.net/media/2022/02/cleansing-No7.jpg" alt="" width="1280" height="720" /></p><p dir="ltr"><em>Image credit: Supplied - No7</em></p><p><span id="docs-internal-guid-1437face-7fff-1449-341c-422b054a5c8a">For a gentle eye makeup remover that won’t leave behind traces of your favourite mascara, look no further than <a href="https://www.priceline.com.au/brand/no7/no7-radiant-results-revitalising-eye-make-up-remover-100-ml">No7 Radiant Results Revitalising Eye Make-Up Remover</a>.</span></p><p><img src="https://oversixtydev.blob.core.windows.net/media/2022/02/eye-No7.jpg" alt="" width="1280" height="720" /></p><p dir="ltr"><em>Image credit: Supplied - No7</em></p><p dir="ltr">A gentle pre-cleanse is essential for any deep clean, with<a href="https://www.priceline.com.au/no7-radiant-results-revitalising-micellar-cleansing-water-200-ml"> No7 Radiant Results Revitalising Micellar Cleansing Water</a> working to capture make-up, impurities and pollutants, drawing them away from the skin in an instant. </p><p><span id="docs-internal-guid-a40944fa-7fff-b343-129f-ea8e24d6b524"><img src="https://oversixtydev.blob.core.windows.net/media/2022/02/micellar-No7.jpg" alt="" width="1280" height="720" /></span></p><p dir="ltr"><em>Image credit: Supplied - No7</em></p><p dir="ltr">Available at <a href="https://www.priceline.com.au/brand/no7">Priceline</a>, these three holy grail products are available for under $20 each, making them a must have to everyone’s skincare regime. </p><p dir="ltr"><em>Image credits: Getty Images / No7</em><span id="docs-internal-guid-3157a1b6-7fff-2307-ef31-e41d41e5893c"></span></p>

7 harmful beauty product ingredients that you should swap out

<p><strong>How harmful are your beauty products?</strong></p> <p><span>A study found there are as many as 126 potentially harmful ingredients in the average adult’s daily beauty routine. </span></p> <p><span>From synthetics in your shampoo to chemicals in your concealer, find out which ingredients you should swap out and why.</span></p> <p><strong>Fragrance</strong></p> <p>“If you only change one thing in your beauty routine, the ingredient you should avoid is fragrance,” says Lindsay Coulter, the David Suzuki Foundation’s resident green living expert.</p> <p>Fragrance isn’t just in colognes or perfumes; in fact, it’s added to everything from body wash to shampoo to face creams. Even unscented products can contain fragrance compounds that act as masking agents.</p> <p>“It shows up as one word [on the ingredients label], but it can be a concoction of hundreds of different ingredients,” Coulter explains.</p> <p>According to research published by the Canadian Cosmetic, Toiletry and Fragrance Association, these anonymous chemical compounds can trigger allergies and asthma, cause hormone disruption, and in many cases, are harmful to fish and other wildlife after they get washed down the drain.</p> <p>Not ready to give up smelling pretty? There are still plenty of green alternatives, says naturopath Jen Newell. “I recommend that people opt for products with essential oils or other natural scents,” Newell says.</p> <p><strong>Parabens</strong></p> <p><span>Parabens are preservatives that can be found in everything from makeup to moisturisers to fragrances. Problem is, numerous studies have shown that these chemicals – which are easily absorbed through the skin – have the potential to interfere with hormone function and have been linked with breast cancer. </span></p> <p><span>How do you rid your beauty routine of this particularly harmful ingredient? Keep an eye out for products that are labelled “paraben-free,” and study the ingredient list carefully, as these pesky preservatives can be listed in different ways, including “methylparaben” or “propylparaben.”</span></p> <p><strong>Triclosan</strong></p> <p>Triclosan is an antibacterial agent that can be found in antibacterial soaps, body washes, hand sanitisers, toothpaste and mouthwash.</p> <p>The issue with triclosan, Coulter says, is that it kills all bacteria – good and bad. Although this ingredient is not yet regulated in Australia, the Food and Drug Administration in the United States banned its use in September 2016 on the grounds that it could pose health risks, including bacterial resistance and hormonal effects.</p> <p>The good news? It’s easy to steer clear of this harmful ingredient, as triclosan is listed on product labels.</p> <p>For an alternative to triclosan, Coulter suggests alcohol-based sanitisers or old-fashioned castile soap and water.</p> <p><strong>Sodium lauryl sulphate</strong></p> <p><span>Sodium lauryl sulphate (SLS, sometimes also known as SLES) is a chemical additive that makes super-foamy bubbles and suds. </span></p> <p><span>It’s often listed as a main ingredient in soap, shampoo, face wash and dish soaps, says Coulter. The reason that SLS should be avoided is that it can be contaminated with ethylene oxide, which the International Agency for Research on Cancer lists as a known human carcinogen (cancer-causing chemical). </span></p> <p><span>Check your soaps for this ingredient before purchasing and don’t fret if the SLS-free product you try doesn’t produce a rich lather like your old shampoo or body wash. </span></p> <p><span>A lack of suds doesn’t mean it’s not doing its job, says Coulter; it simply means you’re skipping out on a harmful chemical.</span></p> <p><strong>Phthalates</strong></p> <p>Phthalates are commonly found in fragrance compounds, says Newell. Research suggests they can disrupt hormones during critical periods of human development (such as a baby’s development in utero) and they’ve also been associated with male infertility.</p> <p>If you’re having trouble identifying which products might contain harmful ingredients such as phthalates, Newell recommends downloading the Think Dirty App to your smartphone.</p> <p>It allows you to scan the bar codes of the products in your daily beauty regimen, and then assesses their degree of safety.</p> <p><strong>Oxybenzone</strong></p> <p><span>Oxybenzone is the active ingredient in many popular sunscreens, but Newell recommends avoiding it when possible – and for good reason. </span></p> <p><span>According to a study published in the </span><em>International Journal of Andrology</em><span>, oxybenzone has been linked to skin reactions and it may even disrupt hormones. </span></p> <p><span>There have also been studies indicating that when oxybenzone is exposed to sunlight it can form free radicals that cause skin cell damage. </span></p> <p><span>This doesn’t mean you should skip sunscreen altogether, of course. It’s easy to avoid this chemical if you stick with mineral-based zinc or titanium oxide sunscreens.</span></p> <p><strong>Petrolatum</strong></p> <p>Petrolatum or petroleum jelly is often used in moisturisers, lip balms and hair products because it acts as a moisture barrier and creates a sheen.</p> <p>The David Suzuki Foundation lists petrolatum as one of its “Dirty Dozen” harmful ingredients to avoid, as it can be contaminated with polycyclic aromatic hydrocarbons (PAHs), which the European Union lists as a carcinogen.</p> <p>If you want to skip petrolatum just to be on the safe side, try organic coconut oil or shea butter to moisturise your skin.</p> <p>If you’re feeling overwhelmed when it comes to “greening” your beauty routine, begin the transition slowly. “Start with the products you use most often and then eventually replace those items that you only use every once in a while,” recommends Newell.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a rel="noopener" href="https://www.readersdigest.com.au/healthsmart/beauty/7-harmful-beauty-product-ingredients-that-you-should-swap-out" target="_blank">Reader's Digest</a>.</em></p>

Nutrient supplements do no good, may do harm

<div class="copy">The only vitamins that help are the ones you get from food, a new study suggests.</div> <div class="copy"> <p>Researchers at Tufts University in the US find that vitamin and mineral supplements are at best a waste of money, and at worst are correlated with increased mortality rates.</p> </div> <div class="copy"> <p>The study, led by nutrition specialist Fang Fang Zhang and <a href="https://dx.doi.org/10.7326/M18-2478">published</a> in the journal Annals of Internal Medicine, finds that adequate intakes of vitamin K and magnesium are associated with lower all-cause mortality rates, but the findings hold true only for intake from food sources, not from vitamin supplements.</p> <p><span style="font-family: inherit;">On the other hand, excess calcium intake, including from supplements, was linked to a higher rate of cancer mortality. </span></p> <p><span style="font-family: inherit;">Vitamin D supplement intake for individuals with no vitamin D deficiency was linked to higher all-cause mortality rates. </span></p> <p>“As potential benefits and harms of supplement use continue to be studied, some studies have found associations between excess nutrient intake and adverse outcomes, including increased risk of certain cancers,” Zhang says.</p> <p>“It is important to understand the role that the nutrient and its source might play in health outcomes, particularly if the effect might not be beneficial.”</p> <p>The study is based on data from 27,725 adults who had answered a range of health and nutrition questions and completed at least one 24-hour food log for the US National Health and Nutrition Examination Survey between 2006 and 2011.</p> <p>More than half of the participants had used at least one dietary supplement within the previous 30 days, with over 38% using a multivitamin or mineral product.</p> <p>Supplement users were more likely than the rest of the population to get nutrients through their food.</p> <p>They were also disproportionately older, wealthier, whiter, more educated, physically active, and female.</p> <p>They were less likely to smoke, drink heavily, or be obese.</p> <p>In other words, they were people with the resources and inclination to take care of their bodies.</p> <p><span style="font-family: inherit;">“Our results support the idea that, while supplement use contributes to an increased level of total nutrient intake, there are beneficial associations with nutrients from foods that aren’t seen with supplements,” said Zhang. </span></p> <p>“This study also confirms the importance of identifying the nutrient source when evaluating mortality outcomes.”</p> <p><em>Image credit: Shutterstock</em></p> <p><em>This article was originally published on <a rel="noopener" href="https://cosmosmagazine.com/health/nutrient-supplements-do-no-good-may-do-harm/" target="_blank">cosmosmagazine.com</a> and was written by Samantha Page.</em></p> </div>

Spanking does more harm than good, study finds

<p><span style="font-weight: 400;">A review of 69 studies from across the world has found physical punishment doesn’t appear to improve a child’s behaviour of social competence in the long run.</span></p> <p><span style="font-weight: 400;">The review was published in </span><span style="font-weight: 400;">The Lancet</span><span style="font-weight: 400;">, one of the world’s oldest and best-known medical journals.</span></p> <p><span style="font-weight: 400;">Elizabeth Gershoff, a professor in human development and family science at The University of Texas at Austin and senior author of the review, said physical punishments such as spanking are “harmful to children’s development and well-being”.</span></p> <p><span style="font-weight: 400;">“Parents hit their children because they think doing so will improve their behaviour,” Professor Gershoff said. “Unfortunately for parents who hit, our research found clear and compelling evidence that physical punishment does not improve children’s behaviour and instead makes it worse.”</span></p> <p><span style="font-weight: 400;">In their research on the impact of spanking and other physical punishments parents might choose to use to discipline a child, the review excluded verbal and “severe” types of punishment that would be classified as child abuse.</span></p> <p><span style="font-weight: 400;">Though some studies included in the review found mixed results - where some positive and negative effects were associated with physical punishment - the majority showed a significant negative impact across a child’s life and behaviours.</span></p> <p><span style="font-weight: 400;">In 13 of 19 independent studies, the most consistent finding was that spanking and other forms of punishment created external problem behaviours over time, Professor Gershoff said, such as “increased aggression, increased antisocial behaviour, and increased disruptive behaviour in school.”</span></p> <p><span style="font-weight: 400;">The review also found that children who were physically punished acted out no matter their sex, race, or ethnicity.</span></p> <p><span style="font-weight: 400;">One study included in the review, conducted in Colombia in South America, found that physically-punished young children gained “fewer cognitive skills” than those who were not.</span></p> <p><span style="font-weight: 400;">Seven of the studies the team reviewed examined the association between a child’s negative behaviour and the frequency of punishment over time, with five finding a “dose-response effect”.</span></p> <p><span style="font-weight: 400;">“In other words, as physical punishment increased in frequency, so did its likelihood of predicting worse outcomes over time,” Professor Gershoff said.</span></p> <p><span style="font-weight: 400;">Other studies in the review found that conduct problems and signs of oppositional defiant disorder - characterised by temper tantrums, argumentative and defiant behaviour, spitefulness, and vindictiveness - were increased by physical punishment.</span></p> <p><span style="font-weight: 400;">In addition to these findings, the review also saw that four of the five studies that considered the influence of parenting styles found that an overall warm and positive parenting style “did not buffer the effect of physical punishment on an increase in behaviour problems.”</span></p> <p><strong>Alternatives to spanking</strong></p> <p><span style="font-weight: 400;">The American Academy of Pediatrics recommends a variety of alternative methods of discipline, which depend on the child’s age.</span></p> <p><span style="font-weight: 400;">“During the first year what infants need is love while they discover new abilities such as crying and making messes,” Dr Robert Sege, a professor and medical doctor who specialises in the study of child abuse, said in an earlier interview. “So parents should distract, by giving them other things to do that are less disruptive or picking them up and moving them to a different place. That’s all they can do.”</span></p> <p><span style="font-weight: 400;">As they become toddlers and continue doing things you don’t want them to, Dr Sege said the best technique is to tap into their need for attention.</span></p> <p><span style="font-weight: 400;">“Toddlers crave their parent’s attention, so use that to your advantage,” he said. “Pay attention to the things your children do that are wonderful; reward them for those with praise. Then when they do something you don’t like, put them in time-out and take the attention away. Use that. That’s how time-outs work.”</span></p> <p><span style="font-weight: 400;">As they get older, he suggests letting children learn the natural consequences of their behaviour.</span></p> <p><span style="font-weight: 400;">“Instead of shielding, help them learn the lesson, as long as they are not in danger,” he said. “Things like, ‘You didn’t put your toys away, so instead of playing, you have to clean them up before we can play.’ It takes parents out of the loop.”</span></p> <p><span style="font-weight: 400;">Teens also need to learn how to take responsibility for their actions, he said.</span></p> <p><span style="font-weight: 400;">“And you do that by calling them out on their behaviour and its consequences and then help them figure out how to resolve those consequences.</span></p> <p><span style="font-weight: 400;">“It’s hard, because it requires, at least at first, a level of mindfulness and thought on what you are doing as a parent,” Dr Sege said. “Parenting isn’t easy. The good thing is that our children excuse us for the mistakes we make.”</span></p>

Turn off the porch light: 6 easy ways to stop light pollution from harming our wildlife

<p>As winter approaches, marine turtle nesting in the far north of Australia <a href="https://www.environment.gov.au/system/files/resources/2eb379de-931b-4547-8bcc-f96c73065f54/files/national-light-pollution-guidelines-wildlife.pdf">will peak</a>. When these baby turtles hatch at night, they crawl from the sand to the sea, using the relative brightness of the horizon and the natural slope of the beach as their guide.</p> <p>But when artificial lights outshine the moon and the sea, these hatchlings become disorientated. This leaves them vulnerable to predators, exhaustion and even traffic if they head in the wrong direction.</p> <p>Baby turtles are one small part of the larger, often overlooked, story of how light pollution harms wildlife across the <a href="https://theconversation.com/getting-smarter-about-city-lights-is-good-for-us-and-nature-too-69556">land</a> and <a href="https://theconversation.com/bright-city-lights-are-keeping-ocean-predators-awake-and-hungry-68965">underwater</a>.</p> <p>Green Turtle’s Battle For Survival | Planet Earth | BBC Earth.</p> <p>Today, more than 80% of people – and 99% of North American and European human populations – <a href="https://advances.sciencemag.org/content/2/6/e1600377">live under light-polluted skies</a>. We have transformed the night-time environment over substantial portions of the Earth’s surface in a very short time, relative to evolutionary timescales. Most wildlife hasn’t had time to adjust.</p> <p>In January, Australia released the <a href="https://www.environment.gov.au/biodiversity/publications/national-light-pollution-guidelines-wildlife">National Light Pollution Guidelines for Wildlife</a>. These guidelines provide a framework for assessing and managing the impacts of artificial light.</p> <p>The guidelines also identify practical solutions that can be used globally to manage light pollution, both by managers and practitioners, and by anyone in control of a light switch.</p> <p>The guidelines outline six easy steps anyone can follow to minimise light pollution without compromising our own safety.</p> <p>Although light pollution is a global problem and true darkness is hard to come by, we can all do our part to reduce its impacts on wildlife by changing how we use and think about light at night.</p> <p><strong>1. Start with natural darkness. Only add light for a specific purpose</strong></p> <p>Natural darkness should be the default at night. Artificial light should only be used if it’s needed for a specific purpose, and it should only be turned on for the necessary period of time.</p> <p>This means it’s okay to have your veranda light on to help you find your keys, but the light doesn’t need to stay on all night.</p> <p>Similarly, indoor lighting can also contribute to light pollution, so turning lights off in empty office buildings at night, or in your home before you go to sleep, is also important.</p> <p><strong>2. Use smart lighting controls</strong></p> <p>Advances in smart control technology make it easy to manage how much light you use, and adaptive controls make meeting the goals of Step 1 more feasible.</p> <p>Investing in smart controls and LED technology means you can remotely manage your lights, set timers or dimmers, activate motion sensor lighting, and even control the colour of the light emitted.</p> <p>These smart controls should be used to activate artificial light at night only when needed, and to minimise light when not needed.</p> <p><strong>3. Keep lights close to the ground, directed and shielded</strong></p> <p>Any light that spills outside the specific area intended to be lit is unnecessary light.</p> <p>Light spilling upward contributes directly to artificial sky glow – the glow you see over urban areas from cumulative sources of light. Both sky glow and light spilling into adjacent areas on the ground can disrupt wildlife.</p> <p>Installing <a href="https://www.ledlightexpert.com/Light-Shields-Explained--Outdoor-Parking-Lot-Light-Shielding_b_42.html">light shields</a> allow you to direct the light downward, which significantly reduces sky glow, and to direct the light towards the specific target area. Light shields are recommended for any outdoor lighting installations.</p> <p><strong>4. Use the lowest intensity lighting</strong></p> <p>When deciding how much light you need, consider the intensity of the light produced (lumens), rather than the energy required to make it (watts).</p> <p>LEDs, for example, are often considered an “environmentally friendly” option because they’re relatively energy efficient. But because of their energy efficiency, LEDs produce between two and five times as much light as incandescent bulbs for the same amount of energy consumption.</p> <p>So, while LED lights save energy, the increased intensity of the light can lead to greater impacts on wildlife, if not managed properly.</p> <p><strong>5. Use non-reflective, dark-coloured surfaces.</strong></p> <p>Sky glow has been shown to <a href="https://www.nature.com/articles/srep01722">mask lunar light rhythms</a> of wildlife, interfering with the celestial navigation and migration of <a href="https://science.sciencemag.org/content/313/5788/837">birds</a> and <a href="https://www.nature.com/articles/424033a">insects</a>.</p> <p>Highly polished, shiny, or light-coloured surfaces – such as structures painted white, or polished marble – are good at reflecting light and so contribute more to sky glow than darker, non-reflective surfaces.</p> <p>Choosing darker coloured paint or materials for outdoor features will help reduce your contribution to light pollution.</p> <p><strong>6. Use lights with reduced or filtered blue, violet and ultra-violet wavelengths</strong></p> <p>Most animals are sensitive to short-wavelength light, which creates blue and violet colours. These short wavelengths are known to suppress melatonin production, which is known to disrupt sleep and interfere with circadian rhythms of many animals, <a href="https://www.mdpi.com/2071-1050/11/22/6400/htm">including humans</a>.</p> <p>Choosing lighting options with little or no short wavelength (400-500 nanometres) violet or blue light will help to avoid unintended harmful effects on wildlife.</p> <p>For example, compact fluorescent and LED lights have a high amount of short wavelength light, compared low or high-pressure sodium, metal halide, and halogen light sources.</p> <p><em>Written by Emily fobert, Katherine Dafforn and Mariana Mayer-Pinto.

Could taking hydroxychloroquine for coronavirus be more harmful than helpful?

<p>A <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(20)31180-6/fulltext">paper published in <em>The Lancet</em></a> has cast fresh controversy on the use of the malaria drug hydroxychloroquine as a potential treatment for COVID-19.</p> <p>The study’s authors reported they were “unable to confirm a benefit” of using the drug, while also finding COVID-19 patients in hospital treated with hydroxychloroquine were more likely to die or suffer life-threatening heart rhythm complications.</p> <p>The publication prompted the World Health Organisation to <a href="https://www.abc.net.au/news/2020-05-26/who-pauses-trial-of-hydroxychloroquine-for-coronavirus-patients/12285652">suspend its testing of hydroxychloroquine to treat COVID-19</a>, while a <a href="https://www.ascot-trial.edu.au/blogs/news/statement-on-the-status-of-australasian-covid-19-trial-ascot">similar Australian trial</a> has paused recruitment.</p> <p><strong>A bit of background</strong></p> <p>Hydroxychloroquine has been used since the 1940s to treat malaria, but has been making headlines as a <a href="https://www.nps.org.au/media/hydroxychloroquine-and-covid-19">potential treatment for COVID-19</a>. US President Donald Trump recently declared <a href="https://theconversation.com/donald-trump-is-taking-hydroxychloroquine-to-ward-off-covid-19-is-that-wise-139031">he was taking it daily</a>, while Australian businessman and politician Clive Palmer <a href="https://www.sbs.com.au/news/the-feed/clive-palmer-has-bought-30-million-doses-of-an-anti-malaria-drug-to-fight-covid-19-but-experts-warn-this-may-not-be-the-cure-all">pledged to create a national stockpile</a> of the drug.</p> <p>The drug alters the human immune system (it’s an <a href="https://www.nps.org.au/hcq-and-covid-19">immunomodulator, not an immunosuppressant</a>) and has an important role in helping people with rheumatoid arthritis and lupus.</p> <p>It does have a range of serious <a href="https://www.tga.gov.au/alert/new-restrictions-prescribing-hydroxychloroquine-covid-19">possible side-effects</a>, including eye damage and altered heart rhythm, which require monitoring.</p> <p><a href="https://www.nature.com/articles/s41421-020-0156-0">Laboratory studies</a> suggest hydroxychloroquine may disrupt replication of the SARS-CoV-2 virus that causes COVID-19. It’s also possible hydroxychloroquine could reduce “<a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7161506/">cytokine storm</a>” – the catastrophic immune system overreaction that happens in some people with severe COVID-19.</p> <p>A huge global effort is underway to investigate whether hydroxychloroquine is safe and effective for preventing or treating COVID-19, especially to improve recovery and reduce the risk of death. Previous studies have been inconclusive as they were anecdotal, observational or small randomised trials.</p> <p>Doubts about hydroxychloroquine’s effectiveness have been increasing, with a large observational study from New York <a href="https://www.nejm.org/doi/full/10.1056/NEJMoa2012410">showing it had no benefit</a> in treating people with COVID-19.</p> <p>The new <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(20)31180-6/fulltext"><em>Lancet</em> study</a>, published last week, has found it could increase the risk of death among COVID-19 patients in hospital. But there’s more to the story.</p> <p><strong>What did the new study do?</strong></p> <p>The <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(20)31180-6/fulltext"><em>Lancet</em> study</a> collected real-world data on more than 96,000 hospitalised patients with COVID-19 from more than 600 hospitals across six continents.</p> <p>About 15,000 patients were treated with hydroxychloroquine (or a closely related drug, chloroquine) alone or in combination with an antibiotic.</p> <p>Using a global registry the researchers investigated the safety of these treatments. They looked at whether people died in hospital, as well as the risk of developing life-threatening heart rhythm problems (called ventricular arrhythmias).</p> <p><strong>What did the study find?</strong></p> <p>Treatment with hydroxychloroquine was associated with increased rates of death in people with COVID-19, even after the researchers adjusted for other factors (age, other health conditions, suppressed immune system, smoking, and severity of the COVID-19 infection) that might increase the risk of death.</p> <p>About 18% of people who received hydroxychloroquine died in hospital, compared with 9% of people with COVID-19 who did not receive these treatments. The risk of death was even higher (24%) in people receiving hydroxychloroquine in combination with either of the antibiotics azithromycin or clarithromycin.</p> <p>Hydroxychloroquine (6%) and chloroquine (4%) treatment was also associated with more cases of dangerous heart rhythm problems when compared with untreated people with COVID-19 (0.3%).</p> <p>Any evidence of benefit, while not the focus of this study, was unclear.</p> <p><strong>How can we interpret the results?</strong></p> <p>This was an observational study, so it can only explore the association between treatments and death – rather than telling us hydroxychloroquine <em>caused</em> these patients to die.</p> <p>It is <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(20)31174-0/fulltext">unclear</a> why the death rate for patients treated with hydroxychloroquine and chloroquine was double that of those who weren’t, as the cause of death was not reported in this study.</p> <p>Importantly, the study cannot account for all the factors that might contribute to death in these hospitalised patients and how these factors interact with each other. However, the researchers did a good job of “<a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3144483/">matching</a>” the characteristics of people who were receiving hydroxychloroquine with those who were not receiving the drug, which makes the results more reliable.</p> <p>But there may still be other factors, or medicines, that contributed to these findings. So there remains uncertainly about whether hydroxychloroquine causes, or even contributes to, the death of people with COVID-19.</p> <p>Further, it was not possible to have careful control over the hydroxychloroquine dose people received – or other medicines people might be taking such as antivirals or other medicines for heart conditions (which potentially interact in sick hospitalised patients).</p> <p>The average dose of hydroxychloroquine in this study was at the upper end of the regular recommended dose range for rheumatoid arthritis and lupus. But the wide range of hydroxychloroquine (and chloroquine) doses in this study makes interpretation of the findings difficult, especially when we know <a href="https://www1.racgp.org.au/ajgp/coronavirus/hydroxychloroquine-use-during-the-covid-19-pandemi">harmful effects</a> are associated with larger doses.</p> <p><strong>Broader implications</strong></p> <p>This study provides important information about the safety of hydroxychloroquine in treating vulnerable people with COVID-19 receiving hospital care.</p> <p>While the implications for using hydroxychloroquine to treat COVID-19 in the community or for prevention of COVID-19 remain unclear, if nothing else this study highlights the need to carefully monitor people receiving the drug.</p> <p>Some hydroxychloroquine trials are continuing, such as the very large <a href="https://www.recoverytrial.net/for-site-staff/site-staff/#alert">RECOVERY trial</a> in the UK.</p> <p>This new information must be considered when balancing harm and potential benefit of these trials and will likely result in renewed safety monitoring.</p> <p>We’ll need to see results from <a href="https://www.mja.com.au/journal/2020/clinical-trials-prevention-and-treatment-coronavirus-disease-2019-covid-19-current">ongoing</a> high-quality randomised controlled trials to truly know if hydroxychloroquine is effective and safe in treating or preventing COVID-19.</p> <p>Further questions about what dose should be used, and which patients will benefit most, are topics under active investigation.</p> <p>You <a href="https://www.tga.gov.au/alert/new-restrictions-prescribing-hydroxychloroquine-covid-19">should not take hydroxychloroquine</a> for COVID-19 unless you’re part of a clinical trial. <strong>– Andrew McLachlan and Ric Day</strong></p> <p><strong>Blind peer review</strong></p> <p>This is a fair and reasonable review of the Lancet paper, its relationship to previous studies, and its impact on ongoing clinical trials.</p> <p>As stated in the review the Lancet article adds to the body of knowledge, including recent substantial studies in the <em><a href="https://www.nejm.org/doi/full/10.1056/NEJMoa2012410">New England Journal of Medicine</a> </em>and the <em><a href="https://www.bmj.com/content/369/bmj.m1849">British Medical Journal</a></em>, that hydroxychloroquine is without significant effect in treatment trials.</p> <p>The high death rate is concerning but not unprecedented, given that a clinical trial in Brazil was <a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2765499">halted</a> because of adverse effects on the heart.

Why celebrity concern about bushfires could do more harm than good

<p>From Australian superstars such as Cate Blanchett, Russell Crowe, Chris Hemsworth and Nicole Kidman to Hollywood heavyweights including Ellen DeGeneres and Bette Midler, a lengthening list of celebrities are helping to shine a spotlight on Australia’s bushfires.</p> <p>Some have donated <a href="https://www.businessinsider.com.au/aussie-celebrities-and-sports-stars-are-pledging-big-donations-to-bushfire-relief-efforts-2020-1">large sums of money </a>and used social media to publicise their donations, encouraging fans to follow suit. Some have used their profile and platforms such as the Golden Globes awards to draw attention to the fires. Others are donating items for auction or appearing in charity events.</p> <p>For attracting attention and money to a cause, celebrity-driven attention is hard to beat. But there’s also a downside. If that interest is superficial and fleeting, it may actually hinder recovery efforts in disaster-ravaged regions.</p> <p>Our research into <a href="https://espace.library.uq.edu.au/view/UQ:263209">disaster recovery efforts for Victoria’s Gippsland region</a> after the deadly “Black Saturday” fires in 2009 suggests celebrities’ best contribution needs to be in the weeks and months to come – and requires them putting “boots on the ground”.</p> <p><strong>Negative implications</strong></p> <p>Studies confirm the influence of messages from celebrities, be it <a href="https://espace.library.uq.edu.au/view/UQ:227015">brand choice</a>, <a href="https://www.researchgate.net/publication/235261651_If_Kate_voted_Conservative_would_you_The_role_of_celebrity_endorsements_in_political_party_advertising">political opinion</a> or <a href="https://news.rutgers.edu/news-release/celebrity-endorsements-lead-increases-charitable-donations-public/20130926#.Xh5oEFczaUk">charitable giving</a>.</p> <p>It’s great that celebrities want to use their influence for good causes. Not all celebrity advocacy, though, should be applauded uncritically. One study has suggested it is <a href="https://journals.sagepub.com/doi/pdf/10.1177/1367877914528532">less effective than sometimes supposed</a> for development causes, and can simplify a complex issue to a single outcome – usually giving money. This fails to address how people can make an ongoing difference in other ways.</p> <p>In terms of natural disasters, a very practical way to help communities recover is the resumption of tourism. Perceptions play a big part in this, and celebrities can play a big part in <a href="https://www.tandfonline.com/doi/pdf/10.1300/J073v02n02_12">forming images</a>. It’s why they have long featured in tourism campaigns, from Paul Hogan in the 1980s to Kylie Minogue and others in the humorously idealised imagery presented by Tourism Australia to Britons a few weeks ago.</p> <div class="embed-responsive embed-responsive-16by9"><iframe class="embed-responsive-item" src="https://www.youtube.com/embed/QMAq8F8N2Fg"></iframe></div> <p>Now these images are being replaced by the message globally that Australia is “<a href="https://www.nbcnews.com/science/environment/australia-fire-literally-so-are-its-climate-politics-n1104351">on fire, literally</a>”, and that much of the country is an “<a href="https://www.greenqueen.com.hk/australia-is-literally-on-fire-because-of-climate-change-so-why-wont-more-governments-act/">apocalyptic nightmare</a>”.</p> <p><strong>Tourism effects</strong></p> <p>Even if celebrities have the best of intentions, their emotional appeals and shared of images of red skies and smoke-filled cities along with heartbreaking images of devastation and loss can contribute to fans cancelling holidays plans, even while they’re donating to bushfire appeals.</p> <p><a href="https://www.sbs.com.au/news/tourism-industry-suffers-as-bushfire-images-scare-off-international-travellers">There are already reports</a>, for example, of tourists aborting plans for visits months away. The <a href="https://qualitytourismaustralia.com/">Australian Tourism Industry Council</a> says cancelled bookings in towns unaffected by the bushfires <a href="https://www.smh.com.au/politics/federal/tourism-industry-takes-1b-hit-as-australians-cancel-their-holidays-20200115-p53rr1.html">are up to 60%</a>. The <a href="https://www.atec.net.au/">Australian Tourism Export Council</a> estimates the loss of international bookings will cost the nation <a href="https://www.afr.com/companies/tourism/tourism-loses-4-5b-to-bushfires-as-overseas-visitors-cancel-20200116-p53s0s">at least A$4.5 billion</a> in 2020, hurting regional areas the most.</p> <p>It doesn’t help when <a href="https://www.abc.net.au/news/2020-01-08/misleading-fire-maps-go-viral-during-australian-bushfire-crisis/11850948">misleading information</a> is spread, as the American singer Rihanna inadvertently did when she <a href="https://www.abc.net.au/news/2020-01-08/misleading-fire-maps-go-viral-during-australian-bushfire-crisis/11850948">shared an image on Twitter</a> that exaggerated the size of the bushfires. This image suggested huge swathes of Australia were no-go zones.</p> <p>Ellen Degeneres did something similar in telling her audience “<a href="https://www.youtube.com/watch?v=gSWveTGTMBA">nearly a third of their habitat has been destroyed</a>”. This was an exaggerated misstatement of Australia’s environment minister saying <a href="https://www.abc.net.au/radio/programs/am/govt-is-working-to-address-threats-to-native-species:-ley/11828480">a third of koala habitat in New South Wales</a> had been destroyed.</p> <p><a href="https://www.sciencedirect.com/science/article/pii/S1447677016300626">Our research confirms</a> the further someone is from a destination in crisis, the more likely they are to be confused about the location and think a greater area is affected.</p> <p>Fires in the Blue Mountains area of New South Wales, for example, were called “the "Sydney fires” elsewhere in Australia. Overseas they were referred to as the “Australian bushfires”, confusing domestic and international tourists.</p> <p><strong>Where celebrities can really help</strong></p> <p>So while celebrities might have the very best of motivations, their contribution in generating donations in the short term might be offset by the longer-term effect of amplifying the misconception that Australia is not safe for tourists.</p> <p>This is demonstrated by past experience. After Victoria’s 2009 Black Saturday fires, the Gippsland region experienced a major tourism downturn, despite just 5% of the region being directly affected.</p> <p>But celebrites can also use their mass-pull to aid tourism recovery.</p> <p><a href="https://www.tandfonline.com/doi/abs/10.1080/10548408.2012.638565">Our research</a> suggests their star power is unmatched as a means to encourage tourists back to regions recovering from disaster.</p> <p>In the case of Gippsland, <a href="https://www.tandfonline.com/doi/full/10.1080/10548408.2012.638565">we surveyed 691 people</a> with nine different advertising messages. Themes included solidarity, community readiness and even short-term discounts. We found celebrity endorsement made the greatest impression, with test subjects indicating it made them more likely to visit the region.</p> <p>In the months after the Black Saturday bushfires, former Miss Universe Jennifer Hawkins and legendary cricketer Shane Warne <a href="https://thenewdaily.com.au/news/national/2019/02/07/black-saturday-media-moments/">visited affected towns</a>. These highly publicised events sent the message these towns were ready to welcome visitors again.</p> <p>So celebrities can definitely help in the coming weeks and months.</p> <p>They can share positive stories about local communities’ resilience, and maybe even visit.</p> <p>This is likely to do more for recovery efforts in the long term than helping to spruik for donations.<!-- Below is The Conversation's page counter tag.

Before you hit ‘share’ on that cute animal photo – consider the harm it can cause

<p>Limbani the chimpanzee has about 650,000 Instagram followers. In recent months the account has featured viral photos and videos of the captive young ape playing the guitar, bouncing on a trampoline and wearing a giant banana costume.</p> <p>Fans are also offered real-life encounters with the chimp at a Miami facility, paying US$700 for a ten-minute session.</p> <p>Experts, including renowned primatologist <a href="https://news.janegoodall.org/2019/04/25/inappropriate-videos-on-social-media-are-hurting-chimpanzees/">Dr Jane Goodall</a>, have raised <a href="http://primatesanctuaries.org/wp-content/uploads/2018/07/Limbani-Chimp-Video-Letter-1.pdf">concerns about Limbani’s care</a>. They question why he is not in the company of other chimpanzees, and say his exposure to humans could cause stress and other health issues.</p> <p>So before you click on or share wildlife content online, it’s worth considering how you might affect a species’ welfare and conservation in the wild.</p> <p><strong>Smiling chimps are actually stressed</strong></p> <p><a href="https://www.tandfonline.com/doi/abs/10.1080/08927936.2018.1406197">Chimpanzees</a> are frequently depicted in greeting cards, advertisements, film, television and internet images. They are often clothed, in human-like poses and settings. These performing animals <a href="https://www.janegoodall.org.au/great-apes/#eluid6c5879d2">are usually taken from their mothers</a> as infants, physically disciplined in training, and can spend their retirement in poorly regulated roadside attractions or breeding facilities.</p> <p>For example the chimpanzee, who appeared with Leonardo DiCaprio in <em>The Wolf of Wall Street</em> <a href="https://www.thesun.co.uk/news/4451790/chance-the-chimp-who-starred-in-wolf-of-wall-street-with-leonardo-dicaprio-tethered-in-a-roadside-zoo-and-yanked-round-by-the-neck/">has reportedly</a> since been kept in a roadside zoo, dragged around by the neck and forced to perform circus tricks.</p> <p>Primates are complex social animals, and the trauma they suffer when forced to perform is often clear. <a href="https://www.taylorfrancis.com/books/9781351243131/chapters/10.4324/9781351243131-12">Research has shown</a> the “cheeky chimp grins” we associate with happiness are actually a sign of fear or submission.</p> <p>But it’s not just primates who are suffering. Earlier this year US banking giant JPMorgan Chase s<a href="https://www.mediapost.com/publications/article/338072/jpmorgan-chase-pulls-elephant-ads.html">uspended an advertising campaign</a> featuring captive elephants. The move followed an outcry from conservationists, <a href="https://www.thedrum.com/news/2019/07/12/jp-morgan-axes-campaign-filmed-with-captive-elephants">who explained</a> that elephants are often trained “using harsh and cruel methods” to perform unnatural behaviours and interact directly with people.</p> <p><strong>Endangered in the wild</strong></p> <p>Images of wildlife in human-like poses and environments can also skew public perception about their status in the wild.</p> <p>For example, the International Union for Conservation of Nature <a href="https://www.iucnredlist.org/species/15933/129038584">classifies chimpazees as endangered</a>. In the last century their numbers have decreased from some <a href="https://www.worldchimpanzeeday.org/">1-2 million to as few as 350,000.</a></p> <p>However research has shown that the prevalence of chimpanzees in media and entertainment can lull viewers into believing wild populations are thriving. This undermines both the need and urgency for in-situ conservation.</p> <p>A 2008 article published in <a href="https://science.sciencemag.org/content/319/5869/1487">Science</a> reported on the findings of two surveys where participants were asked to identify which of three great apes were endangered. In the first, 66% of respondents thought chimpanzees were endangered (compared with 95% for gorillas, and 91% for orangutans). In the second, 72% believed chimpanzees to be endangered (compared with 94% for gorillas and 92% for orangutans).</p> <p>Participants in both studies said the prevalence of chimpanzees in television, advertisements and movies meant they must not be in jeopardy in the wild.</p> <p>A PETA video objecting to a chimp appearing in the film Wolf of Wall Street.</p> <p><strong>Suitability as pets</strong></p> <p>Images of animals in close proximity with humans also affects their perceived desirability as exotic pets. Such images include <a href="https://d31j74p4lpxrfp.cloudfront.net/sites/default/files/ca_-_en_files/amazon_selfies_report_-_canada.pdf">“wildlife selfies”</a> shared on social media by tourists, pet collectors and celebrities.</p> <p>The demand for exotic pets drives the illicit trade in live animals. In Japan, unprecedented demand for otters as pets <a href="https://www.otterspecialistgroup.org/osg-newsite/wp-content/uploads/2018/10/otter-alert-vfinal-web-100-1.pdf">is likely fuelled by an increase</a> in the visibility of pet otters in social and mass media. The pet trade has been identified as <a href="https://d2ouvy59p0dg6k.cloudfront.net/downloads/otter_report_060618_1.pdf">a pressing threat to the survival of otters</a>.</p> <p>Social media provides an easy way for traffickers and buyers to connect. Over six weeks in 2017 in France, Germany, Russia and the UK, the <a href="https://d1jyxxz9imt9yb.cloudfront.net/resource/223/attachment/regular/disrupt-wildlife-cybercrime.pdf">International Fund for Animal Welfare</a> identified more than 11,000 protected wildlife specimens for sale via more than 5,000 advertisements and posts. They included live otters, tortoises, parrots, owls, primates and big cats.</p> <p><a href="https://www.cnbc.com/2018/04/10/facebook-puts-ads-on-pages-illegally-selling-animal-parts.html">Facebook is also allegedly</a> profiting from advertisements on pages illicitly selling parts and derivatives of threatened animals, including elephant ivory, rhino horn and tiger teeth.</p> <p><strong>Slow progress</strong></p> <p>Social media giants have gone some way to recognising the harmful impact of their wildlife content.</p> <p>Facebook and Instagram are partners of the <a href="https://www.endwildlifetraffickingonline.org/">Coalition to End Wildlife Trafficking Online</a> which aims to reduce wildlife trafficking online by 80% by 2020. Both platforms also banned the sale of animals in 2017 – however it is not well policed, and the advertisements persist.</p> <p>In 2017, Instagram <a href="https://www.nationalgeographic.com/news/2017/12/wildlife-watch-instagram-selfie-tourism-animal-welfare-crime/">encouraged users</a> not to harm plants or animals in pursuit of a selfie, and consider the potential animal abuse behind photo opportunities with exotic animals.</p> <p>But there are <a href="https://news.mongabay.com/2019/10/holding-social-media-companies-accountable-for-facilitating-illegal-wildlife-trade-commentary/">persistent claims</a> these measures aren’t proactive or effective enough.</p> <p>There is cause for cautious optimism. Researchers and social media platforms are collaborating to develop <a href="https://theconversation.com/how-machine-learning-can-help-fight-illegal-wildlife-trade-on-social-media-115021">artificial intelligence to help in wildlife trafficking investigations</a> and <a href="https://www.bbc.com/news/science-environment-46945302">facial recognition</a> technology is being used to track individual animals.</p> <p>Social media users are also key in promoting respect and safety for wildlife.

Are you a frequent flyer? Solar storm radiation can be harmful

<p>Space weather <a href="https://theconversation.com/solar-eruption-could-help-earth-prepare-for-technology-melt-down-18747">impacts</a> many modern-day technologies. But one of the most concerning – and least reported – space weather effects is the increased radiation exposure to passengers on commercial long-distance flights during so-called “<a href="http://www.spaceweather.com/glossary/srs.html">solar radiation storms</a>”.</p> <p>The NASA-funded Nowcast of Atmospheric Ionizing Radiation System (<a href="http://sol.spacenvironment.net/~nairas/">NAIRAS</a>) is the computer system tasked with providing a real-time data-driven climatology of the aviation radiation environment.</p> <p>Recently, a series of papers published in the journal [Space Weather] estimate that when NAIRAS was turned off during the US government shutdown last year – which went into effect just as a solar radiation storm began – <a href="http://onlinelibrary.wiley.com/doi/10.1002/2013SW001015/abstract">500,000 people</a> received increased radiation doses.</p> <p>It has also been estimated that this event is likely to eventually result in four cancer-related deaths.</p> <p><strong>What is a solar radiation storm?</strong></p> <p>Disturbances on the surface of the sun are commonly the cause of geomagnetic disturbances here on Earth; such as power grid faults/failures and increased errors in GPS navigation and positioning.</p> <p>Associated with some of these solar disturbances is the ejection of extremely fast plasma into the solar wind that, when aimed directly towards the Earth, causes the onset of increased geomagnetic and ionospheric activity.</p> <p>The Earth-bound solar energetic particles ejected into the solar wind eventually penetrate into the Earth’s magnetosphere.</p> <p>When inside the magnetosphere, they orbit the planet across the Earth’s magnetic field lines until they are scattered by various complicated magnetospheric processes and interactions.</p> <p>Once scattered, these solar particles then travel down the magnetic field lines until they impact the Earth’s upper atmosphere, where they are effectively absorbed.</p> <p>The penetration depth of these particles primarily depends on their kinetic energy, which is governed by their mass and velocity.</p> <p>The less energetic particles are stopped by the Earth’s atmosphere typically between 100 and 400km altitude, causing the well-known <a href="http://spaceweathergallery.com/aurora_gallery.html">aurora</a> in the northern and southern high-latitude regions.</p> <p>The atmosphere increases in density exponentially as the particle falls. This normally prevents particles penetrating to lower altitudes where they are harmful to living organisms.</p> <p>The more energetic particles, called “solar energetic particles”, caused by these solar disturbances can <a href="http://www.dartmouth.edu/~barrel/index.html">penetrate</a> to below 10km, near of commercial flights.</p> <p>During such events, the danger posed by the increased radiation levels is easily averted by decreasing the cruising altitudes of the aircraft. Pilots can also divert their flight paths to areas less affected by the increased radiation levels (more equatorward latitudes).</p> <p><strong>Several chest X-rays worth of radiation</strong></p> <p>The aviation radiation monitoring performed in real-time by computer systems such as NAIRAS can effectively be used to issue such warnings to aircraft.</p> <p>This will help remove the threat posed to hundreds of thousands of people across the globe during such space weather events.</p> <p>The geomagnetic activity levels associated with the solar radiation storm that occurred during the US government shutdown were only minor (a minimum <a href="https://theconversation.com/solar-eruption-could-help-earth-prepare-for-technology-melt-down-18747">Dst</a> of -54nT).</p> <p>This means the technologies normally classified as being <a href="https://theconversation.com/divert-power-to-shields-the-solar-maximum-is-coming-11228">vulnerable</a> to extreme space weather events are not likely to have been significantly affected.</p> <p>The solar energetic particle levels observed by <a href="http://www.ngdc.noaa.gov/stp/satellite/goes/index.html">geostationary satellites</a> classifies this as an <a href="http://www.spaceweather.com/glossary/srs.html">S2</a>solar radiation storm. It lasted more than 24 hours, and took about four days to fully subside (see video below).</p> <p>Some controversy exists around the exact method used by the scientists of the first <a href="http://onlinelibrary.wiley.com/doi/10.1002/2013SW001015/abstract">study</a>into this event. There has been doubt around the estimation of the number of eventual cancer fatalities related to this solar radiation storm.</p> <p>Even though the radiation levels air travellers were exposed to during this event are much higher than they might have been had an appropriate warning been issued, they were still comparatively low – on par with the dose that one would receive from a number of chest X-rays.</p> <p>Arguments put forward by some <a href="http://onlinelibrary.wiley.com/doi/10.1002/2014SW001074/abstract">researchers</a> err on the side of caution. They indicate that some people who would be considered more vulnerable to increased radiation exposure (such as frequent flyers and unborn children) should have access to this radiation monitoring information.</p> <p>This would enable them to make educated decisions about appropriate air travel times in much the same way that non-urgent X-rays may be postponed during pregnancy.</p> <p><a href="http://onlinelibrary.wiley.com/doi/10.1002/2014SW001061/abstract">Other researchers</a> have erred on the opposite side, with the view that the radiation doses during this event were too small to be considered a serious threat.</p> <p>Independent of whether or not this particular space weather event exposed air travellers to dangerous levels of radiation, these studies are in clear agreement that increasing radiation monitoring is a must in the future.</p> <p>This is especially important for the aviation industry, and the provision of such information must not be hindered by short-term political partisan interests.</p> <p><em>Written by Brett Carter.

How streaming music could be harming the planet

<p><span style="font-weight: 400;">Two professors at the University of Oslo have concluded that music streaming has had more of a negative impact on the environment than purchasing a physical product (such as a C.D).</span></p> <p><span style="font-weight: 400;">The study was on the economic and environmental costs of the music industry since the 1970s</span></p> <p><span style="font-weight: 400;">“Intuitively you might think that less physical product means far lower carbon emissions. Unfortunately, this is not the case,” Kyle Devine, an associate at the University of Oslo says.</span></p> <p><span style="font-weight: 400;">Despite the decline in CDs, which has fallen 18.5 per cent since last year, the decline doesn’t offset the environmental cost of maintaining streaming services, such as YouTube, Spotify, Apple Music and Pandora.</span></p> <p><span style="font-weight: 400;">As streaming services utilise large amounts of computing power, servers, storage and cloud capabilities, the increased power usage means more greenhouse gas emissions (GHGs).</span></p> <p><span style="font-weight: 400;">Devine calculated that 140 million kilograms of GHGs were emitted in 1977, which was calculated by converting past plastic production to emissions.</span></p> <p><span style="font-weight: 400;">Using the same formula, it was discovered that the recorded music industry emitted between 200 million and 350 million kg of GHGs in 2016.</span></p> <p><span style="font-weight: 400;">Devine revealed to </span><a href="https://www.express.co.uk/news/science/1120086/Climate-change-plastic-CD-listen-music-global-warming-study-Spotify-Apple-Amazon"><span style="font-weight: 400;">Express</span></a><span style="font-weight: 400;"> that he was surprised by the results.</span></p> <p><span style="font-weight: 400;">“I am a bit surprised. The hidden environmental cost of music consumption is enormous.”</span></p> <p><span style="font-weight: 400;"> He reveals more in his book </span><span style="font-weight: 400;">Decomposed: The Political Ecology of Music.</span><span style="font-weight: 400;"> A brief summary of the book reads:</span></p> <p><span style="font-weight: 400;">“Today, recordings exist as data-based audio files. Devine describes the people who harvest and process these materials, from women and children in the Global South to scientists and industrialists in the Global North.</span></p> <p><span style="font-weight: 400;">“He reminds us that vinyl records are oil products, and that the so-called vinyl revival is part of petrocapitalism.</span></p> <p><span style="font-weight: 400;">“The supposed immateriality of music as data is belied by the energy required to power the internet and the devices required to access music online.</span></p> <p><span style="font-weight: 400;">“We tend to think of the recordings we buy as finished products. Devine offers an essential backstory.”</span></p>

How to enjoy wildlife without harming it

<p>The next time you want to take a selfie with a tiger, ride an elephant or swim with dolphins, stop to consider the consequences.</p> <p>That's what animal welfare groups have been saying for a long time. Now, more and more tour operators, online travel agencies and social media sites are starting to listen.</p> <p>Wildlife tourist attractions account for 20 to 40 per cent of global tourism, which produces more than US$1 trillion a year, according to a report from PLOS One, a peer-reviewed scientific journal.</p> <p>But advocacy groups say many animals - especially endangered species - end up being exploited to entertain their guests.</p> <p>"Well-meaning people are often duped by 'wildlife' attractions, unaware of the cruelty that animals endure in captivity," says Ben Williamson, senior international media director at People for the Ethical Treatment of Animals (PETA). Williamson advises travellers to steer clear of any venue that lets you "ride, hug, or take a selfie with an elephant, tiger, dolphin, or other wild animal".</p> <p>There is still disagreement around the world about engaging in certain wildlife tourist activities. For instance, elephant rides continue to be offered in Thailand, India and many other countries.</p> <p>But in the US, online travel agencies TripAdvisor and Expedia no longer sell experiences that involve the unethical treatment of animals. Instagram late last year started flagging particular wildlife-related hashtags and notifying users of the abuse some animals experience when being posed for photos. Other travel companies such as Trafalgar and Worldwide Expeditions have also altered their policies.</p> <p>TripAdvisor, parent company of Viator travel agency, introduced its new animal welfare policy in late 2016, removing ticket sales for attractions that put travellers in physical contact with wild captive animals and endangered species.</p> <p>Earlier this week, the company revised its policy to include a ban on certain types of animal shows that it considers demeaning to animals, such as dressing up orangutans as boxers in Asia.</p> <p>"There isn't really a universally agreed to criteria on what's on the right side or wrong side of the line," says James Kay, associate director of TripAdvisor. "We needed to say where we stood and where the line was for us."</p> <p>The line for Williamson is clear. He recommends that people be cautious of animal mistreatment when considering camel rides at the Pyramids of Giza in Egypt, donkey rides at Blackpool beach in the United Kingdom, and horse rides at Taal Volcano in the Philippines, to name a few. Sometimes the animals are not given enough food or water, or suffer other forms of physical abuse.</p> <p>Even zoos and circuses have come under fire for the way they handle animals. In 2016, SeaWorld ended its orca, or killer whale, breeding program. That same year, Ringling Brothers stopped parading elephants and sent them to a Florida conservation centre.</p> <p>The treatment of elephants, in particular, has disturbed the animal welfare community. A World Animal Protection report last year found that more than 3/4 of nearly 3000 elephants used for entertainment in Asia are kept in cruel conditions.</p> <p>Many elephants at tourist attractions were typically kept chained day and night. They had poor diets and got limited veterinary care, the report found.</p> <p>The problem has become more visible in the digital age. Taking a selfie is often considered innocuous, but for many animals, it can cause stress and suffering, according to another World Animal Protection report. The animals are often beaten, taken away from their mothers and kept in dirty environments, the report said. There is also an illegal trade involving poachers going into the wilderness to capture exotic or endangered animals.</p> <p>Elizabeth Hogan, campaign manager for oceans and wildlife at World Animal Protection, advises that travellers think about the circumstances that led to the animal ending up in a photo op.</p> <p>"This is a wild animal," she says. "Your actions, your desire for that photo, that selfie means that animal is not engaging in its natural behaviour. If you're holding a two week-old tiger cub and feeding it with a bottle, where is that animal's mother?"</p> <p>Instagram revised its policy last year after a World Animal Protection report found that there was a 292 per cent increase in the number of wildlife selfies posted on Instagram between 2014 and last year. More than 40 per cent of those were "bad" selfies, showing someone hugging, holding or inappropriately interacting with a wildlife animal.</p> <p>"Social media is definitely playing a role here in shaping the way people are seeing wildlife," Hogan says.</p> <p>That's not to say that all wildlife tourism outside of wild lands is bad. There are plenty of wildlife sanctuaries around the world that let animals live as naturally as possible without physically encountering visitors.</p> <p>While not all zoos and aquariums are accredited, those in the US and across the world that earn it have to undergo rigorous standards. In the US, the Association of Zoos and Aquariums requires the facilities to participate in conservation and research activities. The American Humane Association also sends independent audit teams into zoos and aquariums.</p> <p>Christopher Dold, chief zoological officer at SeaWorld Parks and Entertainment, says the the mission of any zoo or aquarium is to expose people to animals they have never seen before as a way to make them care enough to want to keep that species alive.</p> <p>"Those opportunities are critically important for conservation," Dold says. "Can we engage as much of the public, as much of a society to care for and understand and know about these animals as much as possible?"</p> <p>Still it's hard for a traveller to discern what is the right thing to do when it comes to wildlife when tour companies around are still offering excursions such as swimming with dolphins.</p> <p>Williamson, of PETA, says the best way to take the guesswork out of planning is to book your trip through an agency that specialises in animal-friendly travel, such as Humane Travel.</p> <p>Many of the travel companies that have adopted new animal welfare procedures also have educational components to them. Activities that involve any animals on TripAdvisor and Viator have paw print icons affixed next to them that send users to an education portal.</p> <p>The portal includes articles from the dozen or so animal advocacy groups TripAdvisor consulted with when first introducing its new policy. They include Global Wildlife Conservation, the Association of Zoos and Aquariums, Oxford University WILDCRU, Think Elephants, and Sustainable Travel International.</p> <p>"Where we can have the greatest impact is having consumers as informed as possible and having them making ethical choices they are comfortable with," Kay says.</p> <p>Do you agree with this?</p> <p><em>Written by Nancy Trejos.

7 bedtime mistakes that are harming your skin

<p>While we sleep, our skin makes the most of the downtime to repair and rejuvenate. But there are a few common bedtime practices that you might be doing that could be making it hard for this to happen. See if you are making any of these mistakes.</p> <p><strong>1. Going to bed without cleansing your face</strong></p> <p>There is a reason this is number one – it’s the most important! Even if you don’t wear makeup, your skin takes on pollutants, dust and grime throughout the day which need to be removed. If you don’t, you’re going to bed with skin that can’t breathe, let alone get rid of dead skin cells. A simple cleanse over the sink is all you need.</p> <p><strong>2. Using too-hot or too-cold water</strong></p> <p>But when you do clean your face, keep the water at a gentle temperature. Too much extreme in terms of very hot or very cold water is too harsh on your delicate skin.</p> <p><strong>3. Waiting until bedtime to wash your face</strong></p> <p>Normally people scrub just before bed, but why wait? If you wash your face as soon as you get home, it gives your skin a few extra hours to breathe a bit easier before you retire for the night. </p> <p><strong>4. Only using moisturiser</strong></p> <p>Once we hit 30, our skin needs more support in the form of retinoid cream. This is in addition to a moisturiser or night cream. You don’t need to head to the dermatologist though, you can pick one up from most department stores or chemists.</p> <p><strong>5. Using too many products</strong></p> <p>If you are in the ‘more is better’ camp, you could be spending money you don’t need to on the latest eye creams, scrubs, cleansers and moisturisers. Try sticking to just a couple of products, ideally from the same range so that you know they compliment each other rather than compete.</p> <p><strong>6. Forgetting other areas of your body </strong></p> <p>It’s easy to focus on the face, but you want to remember to moisturise all of your skin. Use your face creams all the way down your neck and chest. Then at least once a week, moisturise your whole body after a shower.</p> <p><strong>7. Drinking coffee or wine before bed</strong></p> <p>Hydration is the key to softer skin, so it’s best to avoid moisture-suckers like caffeine or alcohol if you want to look your best. Go for a herbal tea instead that will support a good night’s sleep, such as chamomile or valerian. </p> <p>Have you got any tips for younger looking skin that you would like to share?

Do antibacterial products do more harm than good?

<p><span>Most hand sanitiser products brand their products with the claim that it “kills 99.9 per cent of household germs”.</span></p> <p><span>However, Professor Liz Harry, director of the ithree institute (Infection, immunology and innovation) at the University of Technology Sydney, says this claim is giving consumers a false sense of security.</span></p> <p><span>“It's not the percentage of germs that matters but the absolute numbers – if there are billions of germs and you kill 99.9 per cent of them, the remaining one per cent can still represent a lot of germs – and you don't know whether they're harmful or not," she told th</span><em><span>e Sydney Morning Herald.</span></em></p> <p><span>Professor Harry believes that the widespread use of antibiotics and antibacterial products is empowering germs to outsmart us.</span></p> <p><span>"Bacteria have been around for billions of years – they've learned to defend themselves and have developed genes that resist antibiotics as well as genes that resist antibacterial chemicals. They can also spread these genes to other neighbouring bacteria within minutes," she said.</span></p> <p><span>Germs not only pass their resistance to antibiotics and antibacterial chemicals from one generation to another, but they pass it on to their neighbours too.</span></p> <p><span>"There are times when you need antibacterial solutions but we don't need to spread them around willy nilly. If you use a lot of antibacterial products you risk enriching your home with more bacteria that are resistant to antibiotics and antibacterial chemicals," she added.</span></p> <p><span>"The US has banned a number of antibacterial chemicals including triclosan for domestic use because they're not needed in the home and their overuse can make them less effective in hospitals. I think we need to be stricter about regulating some of these chemicals in Australia."</span></p> <p><span>Beneficial bacteria can also be killed off in the overuse of antibacterial products.</span></p> <p><span>"Microbes are part of our world. Most of our body is made up of microbes – and we need most of them to live," said Professor Harry. "They play a role in our defence systems – they stimulate the immune system and help protect our skin, for example."  </span></p> <p><span>Like Professor Harry, Professor Peter Collignon from the Australasian College of Infection Prevention and Control believes that antibacterial products are giving us a false sense of security and are making us less vigilant about doing things like handwashing with regular soap.</span></p> <p><strong>What to do</strong></p> <p><span>"In most situations hot soapy water will do the job along with elbow grease – it's the vigorous physical scrubbing that helps remove bacteria. Alcohol hand rubs are useful when someone is sick or when you're travelling. Vinegar is a useful disinfectant and like alcohol is biodegradable," he said.</span></p> <p><span>Vinegar won’t kill salmonella so surfaces and objects used for raw meat, poultry or fish need cleaning with hot soapy water.</span></p> <p><span>He recommends washing kitchen sponges frequently in hot soapy water or in the dishwasher, and letting them dry out before use.</span></p> <p><span>It is also important to wash hands frequently with hot water.</span></p> <p><span>"Use hot water and normal soap, not antibacterial soap – and scrub your hands like a surgeon," Liz Harry said.</span></p> <p><span>Do you use a lot of antibacterial products in your home and hand sanitiser when travelling or out in public?

Fashion choices that are causing you harm

<p>Throughout our lives, many of us, will make some kind of sacrifice in the name of fashion. Whether financial or physical, forgoing a certain level of comfort in a quest to look our best is par for the course, right? You may have already guessed, but allowing your body to suffer for fashion could be doing lasting damage to it. Let’s take a look at some of the things you should avoid or limit and why.</p> <p><strong>1. High heel shoes</strong></p> <p>This one’s a no-brainer. We’ve known for years that high heels aren’t great for your posture, despite the way they appear to make women stand up taller when wearing them. According to the <a href="http://www.thespinehealthinstitute.com/news-room/health-blog/how-high-heels-affect-your-body" target="_blank"><strong><span style="text-decoration: underline;">Spine Health Institute</span></strong></a>, heels can “take their toll on your spine, hips, knees, ankles and feet, while altering your posture and gait.” Phew, that’s a lot just for one pair of shoes. Wearing high heels will cause a woman to push her chest and lower back forwards, throwing the hips and spine out of alignment, places excess pressure on the knees and balls of the feet. The Spine Health Institute recommends women avoid wearing high heels for long periods, and setting a two-inch limit, as well as mixing footwear up with flats and sneakers to give your feet a break.</p> <p><strong>2. Skinny jeans</strong></p> <p>The British Chiropractic Association (BCA) <a href="http://www.dailymail.co.uk/wires/pa/article-4312282/Skinny-jeans-heavy-hoodies-hurt-chiropractors-warn.html" target="_blank"><strong><span style="text-decoration: underline;">have revealed</span></strong></a> that many seem unaware of the negative impact the popular “skinny jean” can have on a body. The tight-fitting denim “restrict free movement in areas such as the hips and knees, affecting the way we hold our bodies.” This restricted movement can have a negative impact on postures, as well as the spine, as well as limiting the “bounce” in one’s stride, causing pressure on joints throughout the body.</p> <p><strong>3. Shapewear</strong></p> <p>In the never-ending quest to achieve the “perfect silhouette”, many women turn to constricting undergarments, often known as “shapewear”, to press their bodies into submission. However, the tightness can lead to incredible pain and even numbness. In some cases, the fabrics can harbor bacteria, leading to nasty things like yeast infections.</p> <p><strong>4. Heavy handbags</strong></p> <p>Large handbags, which lend themselves to being filled up with everyday bits and pieces, cause back, shoulder and elbow problems. While it can seem convenient to have everything one could possible need within reach at all times, the reliance on handbags to contain one’s life could end up sending you to the chiropractor. The BCA recommend investing in a backpack or cross-body bag for days when you have a lot of necessities.</p> <p>Tell us in the comments below about a fashion choice you’ve made at the expense of your comfort or health.</p>
