I have hay fever. How can I tell what I’m allergic to?

<p><em><a href="https://theconversation.com/profiles/ryan-mead-hunter-1480189">Ryan Mead-Hunter</a>, <a href="https://theconversation.com/institutions/curtin-university-873">Curtin University</a></em></p> <p>When we think of spring we think of warming weather, birdsong and flowers. But for many people, this also means the return of their seasonal hay fever symptoms.</p> <p>Around <a href="https://www.abs.gov.au/statistics/health/health-conditions-and-risks/health-conditions-prevalence/latest-release">24% of Australians</a> get hay fever, with sneezing, a runny or blocked nose, and itchy or watery eyes the most common symptoms. In <a href="https://www.healthdirect.gov.au/hay-fever#:%7E:text=Key%20facts,dust%20mites%2C%20and%20animal%20fur">severe cases</a>, this may impact sleep and concentration, or be linked to increased frequency of sinus infections.</p> <p>The exact timing of the symptoms depends on your exposure to an allergen – the thing you’re allergic to. Those impacted by tree pollen (from plane trees or cypress pine, for example) may experience symptoms at different times of the year than those impacted by grass pollen (such as rye grass). This will also vary around the country.</p> <p>In Perth, for example, tree pollen (cypress pine) is generally present in August to October, while grass pollen counts tend to be highest in October to November. Other cities and regions may have longer pollen seasons, which may extend further into summer.</p> <h2>Remind me, how does hay fever impact the body?</h2> <p>What we know colloquially as hay fever is called allergic rhinitis. Exposure to a specific allergen (or allergens) triggers an immune response in the body. This leads to inflammation and swelling of the tissue lining the nasal passages in the nose.</p> <p>A range of <a href="https://www.healthdirect.gov.au/hay-fever#:%7E:text=Key%20facts,dust%20mites%2C%20and%20animal%20fur.">allergens</a> may trigger such a response: pollen (from trees, grass or weeds), dust mites, pet fur, dander, mould and some air pollutants.</p> <p>Those with allergies that are only present for part of the year, such as pollen, experience what we call seasonal hay fever, while those with allergies that may be present at any time, such as dust mites and pet dander, experience perennial hay fever.</p> <h2>Getting a diagnosis</h2> <p>Many people with hay fever self-manage their symptoms by limiting exposure to allergens and using over-the-counter <a href="https://theconversation.com/how-do-hay-fever-treatments-actually-work-and-whats-best-for-my-symptoms-213071">antihistamines and steroid nasal sprays</a>.</p> <p>But this may require assistance from your GP and confirmation that what you’re experiencing is hay fever. Your GP can assess your symptoms and medical history, provide a diagnosis, and help with treating and managing your symptoms.</p> <p>Your GP may also be able help you identify potential allergens, based on when you experience symptoms and the environments to which you’re exposed.</p> <p>If symptoms persist, your GP may suggest allergy testing. They may refer you to a specialist called an immunologist, to determine what particular allergen is causing your symptoms, using <a href="https://www.allergy.org.au/patients/allergy-testing/allergy-testing">skin prick tests or blood tests</a>. Tests typically involve controlled exposure to small quantities of suspected allergens.</p> <p>But note, there are a number of tests marketed online that are unproven and not recommended by reputable bodies.</p> <h2>How else can I work out what I’m allergic to?</h2> <p>For those with seasonal hay fever, resources are available to help manage exposures, based on the flowering seasons for common allergy-related species or through pollen forecasting services.</p> <p>The Australian Society of Clinical Immunology and Allergy provides a <a href="https://www.allergy.org.au/patients/allergic-rhinitis-hay-fever-and-sinusitis/guide-to-common-allergenic-pollen">useful pollen guide</a> for each species and when they’re most likely to cause symptoms, broken down for each state and territory.</p> <p>Pollen monitoring and forecasting services – such as <a href="https://www.perthpollen.com.au/">Perth Pollen</a>, <a href="https://www.melbournepollen.com.au/">Melbourne Pollen</a> and <a href="https://www.sydneypollen.com.au/">Sydney Pollen</a>, as well as for other cities – can help you plan outdoor activities.</p> <p>There are also associated phone apps for these services, which can give notifications when the pollen count is high. You can down load these apps (such as <a href="https://airrater.org/">AirRater</a>, Perth Pollen, Melbourne Pollen and Sydney Pollen) from your preferred app store.</p> <p>Apps such as <a href="https://airrater.org/">AirRater</a> also allow you to enter information about your symptoms, which can then be matched to the environmental conditions at the time (pollen count, temperature, smoke, and so on).</p> <p>Using statistical modelling, the app may be able to establish a link between symptoms and exposure. If a sufficiently high correlation is established, the app can send you notifications when the <a href="https://airrater.org/how-does-it-work/">exposure risk</a> is high. This may prompt you to limit outdoor activities and have any medication readily available.</p> <hr /> <p><em>Further information about managing allergic rhinitis is available from <a href="https://www.healthdirect.gov.au/hay-fever">healthdirect</a> and <a href="https://allergyfacts.org.au/__interest/allergic-rhinitis/">Allergy and Anaphylaxis Australia</a></em></p> <p><em><a href="https://theconversation.com/profiles/ryan-mead-hunter-1480189">Ryan Mead-Hunter</a>, Senior lecturer, School of Population Health, <a href="https://theconversation.com/institutions/curtin-university-873">Curtin University</a></em></p> <p><em>Image </em><em>credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Why do I have hay fever? I didn’t have it as a child

<p><em><a href="https://theconversation.com/profiles/janet-davies-103598">Janet Davies</a>, <a href="https://theconversation.com/institutions/queensland-university-of-technology-847">Queensland University of Technology</a> and <a href="https://theconversation.com/profiles/joy-lee-1480523">Joy Lee</a>, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a></em></p> <p>Hay fever (or allergic rhinitis) is a long-term inflammatory condition that’s incredibly common. It affects about <a href="https://www.abs.gov.au/statistics/health/health-conditions-and-risks/national-health-survey-state-and-territory-findings/latest-release">one-quarter</a> of Australians.</p> <p>Symptoms vary but <a href="https://www.allergy.org.au/patients/fast-facts/hay-fever-allergic-rhinitis">can include</a> sneezing, itchy eyes and a runny or blocked nose. Hay fever can also contribute to sinus and ear infections, snoring, poor sleep and asthma, as well as lower performance at school or work.</p> <p>But many people didn’t have hay fever as a child, and only develop symptoms as a teenager or adult.</p> <p>Here’s how a combination of genetics, hormones and the environment can lead to people developing hay fever later in life.</p> <h2>Remind me, what is hay fever?</h2> <p>Hay fever is caused by the nose, eyes and throat coming into contact with a substance to which a person is allergic, known as an allergen.</p> <p>Common sources of outside allergens include airborne grass, weed or tree pollen, and mould spores. Pollen allergens can be carried indoors on clothes, and through open windows and doors.</p> <p>Depending on where you live, you may be exposed to a range of pollen types across the pollen season, but grass pollen is the most common trigger of hay fever. In <a href="https://www.sciencedirect.com/science/article/abs/pii/S0013935122010891?via%3Dihub">some regions</a> the grass pollen season can extend from spring well into summer and autumn.</p> <h2>How does hay fever start?</h2> <p>Hay fever symptoms most commonly start in adolescence or young adulthood. <a href="http://dx.doi.org/10.2147/JAA.S170285">One study</a> found 7% of children aged six had hay fever, but that grew to 44% of adults aged 24.</p> <p>Before anyone has hay fever symptoms, their immune system has already been “sensitised” to specific allergens, often allergens of grass pollen. Exposure to these allergens means their immune system has made a particular type of antibody (known as IgE) against them.</p> <p>During repeated or prolonged exposure to an allergen source such as pollen, a person’s immune system may start to respond to another part of the same allergen, or another allergen within the pollen. Over time, these new allergic sensitisations can lead to development of <a href="https://www.jacionline.org/article/S0091-6749(12)00959-1/fulltext">hay fever</a> and possibly other conditions, such as allergic asthma.</p> <h2>Why do some people only develop hay fever as an adult?</h2> <p><strong>1. Environmental factors</strong></p> <p>Some people develop hay fever as an adult simply because they’ve had more time to become sensitised to specific allergens.</p> <p>Migration or moving to a new location can also change someone’s risk of developing hay fever. This may be due to exposure to different <a href="https://www.sciencedirect.com/science/article/abs/pii/S0048969722076884">pollens</a>, <a href="https://www.sciencedirect.com/science/article/pii/S0048969724060194?via%3Dihub">climate and weather</a>, green space <a href="https://onlinelibrary.wiley.com/doi/epdf/10.1111/all.14177">and/or</a> air quality factors.</p> <p>A number of studies <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0105347">show</a> people who have migrated from low- and middle-income countries to higher-income countries may be at a higher risk of developing hay fever. This may due to local environmental conditions influencing expression of genes that regulate the immune system.</p> <p><strong>2. Hormonal factors</strong></p> <p><a href="http://dx.doi.org/10.1016/j.anai.2015.04.019">Hormonal changes</a> at puberty may also help drive the onset of hay fever. This may relate to sex hormones, such as oestrogen and progesterone, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9392967/#R55">affecting</a> histamine levels, immune regulation, and the response of cells in the lining of the nose and lower airways.</p> <p><strong>3. Genetic factors</strong></p> <p><a href="https://www.nature.com/articles/ng.3985">Our genes</a> underpin <a href="https://www.ncbi.nlm.nih.gov/books/NBK542187/">our risk</a> of hay fever, and whether this and other related allergic disease persists.</p> <p>For instance, babies with the skin condition eczema (known as atopic dermatitis) have a <a href="https://www.annallergy.org/article/S1081-1206(21)00172-1/abstract">three times greater risk</a> of developing hay fever (and asthma) later in life.</p> <p>Having a food allergy in childhood is also a risk factor for developing hay fever later in life. In the case of a peanut allergy, that risk is more than <a href="https://pubmed.ncbi.nlm.nih.gov/27542726/">2.5 times greater</a>.</p> <h2>What are the best options for treatment?</h2> <p>Depending on where you live, avoiding allergen exposures can be difficult. But <a href="https://auspollen.edu.au/auspollensitesmap/">pollen count forecasts</a>, if available, can be useful. These can help you decide whether it’s best to stay inside to reduce your pollen exposure, or to take preventative medications.</p> <p>You may also find <a href="https://www.health.vic.gov.au/environmental-health/epidemic-thunderstorm-asthma-risk-forecast">alerts on thunderstorm asthma</a>, where pollens combine with specific weather conditions to trigger <a href="https://theconversation.com/we-could-see-thunderstorm-asthma-in-south-eastern-australia-this-season-heres-how-to-prepare-215793">breathing difficulties</a>.</p> <p>If you have mild, occasional hay fever symptoms, you can take non-drowsy antihistamines, which you can buy at the pharmacy.</p> <p>However, for more severe or persistent symptoms, intranasal steroid sprays, or an intranasal spray containing a steroid with antihistamine, are the <a href="https://theconversation.com/can-i-take-antihistamines-everyday-more-than-the-recommended-dose-what-if-im-pregnant-heres-what-the-research-says-228390">most effective treatments</a>. However, it is important to use these <a href="https://allergyfacts.org.au/allergic-rhinitis-treatment/">regularly and correctly</a>.</p> <p>Allergen immunotherapy, also known as desensitisation, is an <a href="https://onlinelibrary.wiley.com/doi/10.1111/all.13201">effective treatment</a> for people with severe hay fever symptoms that can reduce the need for medication and avoiding allergens.</p> <p>However, it involves a longer treatment course (about three years), usually with the supervision of an allergy or immunology specialist.</p> <h2>When should people see their doctor?</h2> <p>It is important to treat hay fever, because symptoms can significantly affect a <a href="https://bmjopen.bmj.com/content/10/11/e038870.long">person’s quality of life</a>. A GP can:</p> <ul> <li> <p>recommend treatments for hay fever and can guide you to use them correctly</p> </li> <li> <p>organise blood tests to confirm which allergen sensitisations (if any) are present, and whether these correlate with your symptoms</p> </li> <li> <p>screen for asthma, which commonly exists with hay fever, and may require other treatments</p> </li> <li> <p>arrange referrals to allergy or immunology specialists, if needed, for other tests, such as allergen skin prick testing, or to consider <a href="https://www.allergy.org.au/patients/allergy-treatments/allergen-immunotherapy">allergen immunotherapy</a> if symptoms are severe.</p> </li> </ul> <hr /> <p><em>More information about hay fever is available from the <a href="https://www.allergy.org.au/patients/fast-facts/hay-fever-allergic-rhinitis">Australasian Society of Clinical Immunology and Allergy</a> and <a href="https://allergyfacts.org.au/">Allergy &amp; Anaphylaxis Australia</a>.</em><img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/239409/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/janet-davies-103598">Janet Davies</a>, Respiratory Allergy Stream Co-chair, National Allergy Centre of Excellence; Professor and Head, Allergy Research Group, <a href="https://theconversation.com/institutions/queensland-university-of-technology-847">Queensland University of Technology</a> and <a href="https://theconversation.com/profiles/joy-lee-1480523">Joy Lee</a>, Respiratory Allergy Stream member, National Allergy Centre of Excellence; Associate Professor, School of Translational Medicine, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

An unbroken night’s sleep is a myth. Here’s what good sleep looks like

They’re in good company – many Australians hold <a href="https://doi.org/10.1016/j.jpsychores.2014.09.011">the same belief</a>.</p> <p>In reality, healthy sleep is cyclic across the night, as you move in and out of the different stages of sleep, often waking up several times. Some people remember one or more of these awakenings, others do not. Let’s consider what a healthy night’s sleep looks like.</p> <h2>Sleep cycles are a roller-coaster</h2> <p>As an adult, our sleep moves through <a href="https://www.sleepfoundation.org/stages-of-sleep">different cycles</a> and brief awakenings during the night. Sleep cycles last roughly 90 minutes each.</p> <p>We typically start the night with lighter sleep, before moving into deeper sleep stages, and rising again into rapid eye movement (REM) sleep – the stage of sleep often linked to vivid dreaming.</p> <p>If sleeping well, we get most of our deep sleep in the first half of the night, with <a href="https://www.nhlbi.nih.gov/health/sleep/stages-of-sleep#:%7E:text=During%20REM%20sleep%2C%20your%20eyes,from%20acting%20out%20your%20dreams">REM sleep</a> more common in the second half of the night.</p> <p>Adults usually move through five or six sleep cycles in a night, and it is entirely <a href="https://doi.org/10.1016/j.jpsychores.2014.09.011">normal</a> to wake up briefly at the end of each one. That means we might be waking up five times during the night. This can increase with older age and still be healthy. If you’re not remembering these awakenings that’s OK – they can be quite brief.</p> <h2>What does getting a ‘good’ sleep actually mean?</h2> <p>You’ll often hear that adults <a href="https://www.sleephealthfoundation.org.au/sleep-topics/how-much-sleep-do-you-really-need#:%7E:text=Sleep%20requirements%20stabilise%20in%20early,their%20best%20the%20next%20day">need between seven and nine hours</a> of sleep per night. But good sleep is about more than the number of hours – it’s also about the quality.</p> <p>For most people, sleeping well means being able to fall asleep soon after getting into bed (within around 30 minutes), sleeping without waking up for long periods, and waking feeling rested and ready for the day.</p> <p>You shouldn’t be feeling excessively sleepy during the day, especially if you’re regularly getting at least seven hours of refreshing sleep a night (this is a rough rule of thumb).</p> <p>But are you noticing you’re feeling physically tired, needing to nap regularly and still not feeling refreshed? It may be worthwhile touching base with your general practitioner, as there a range of possible reasons.</p> <h2>Common issues</h2> <p>Sleep disorders are common. Up to <a href="https://pubmed.ncbi.nlm.nih.gov/35478719/">25% of adults</a> have insomnia, a sleep disorder where it may be hard to fall or stay asleep, or you may wake earlier in the morning than you’d like.</p> <p>Rates of common sleep disorders such as insomnia and <a href="https://www.mayoclinic.org/diseases-conditions/sleep-apnea/symptoms-causes/syc-20377631">sleep apnoea</a> – where your breathing can partially or completely stop many times during the night – also increase with age, affecting <a href="https://pubmed.ncbi.nlm.nih.gov/32280974/">20% of early adults</a> and 40% of people in <a href="https://pubmed.ncbi.nlm.nih.gov/35082023/">middle age</a>. There are effective treatments, so asking for help is important.</p> <p>Beyond sleep disorders, our sleep can also be disrupted by chronic health conditions – such as <a href="https://www.sciencedirect.com/science/article/abs/pii/S0012369218311139">pain</a> – and by <a href="https://onlinelibrary.wiley.com/doi/10.1111/jsr.13075">certain medications</a>.</p> <p>There can also be other reasons we’re not sleeping well. Some of us are woken by children, pets or traffic noise during the night. These “<a href="https://www.tandfonline.com/doi/full/10.1080/07420528.2021.2003375">forced awakenings</a>” mean we may find it harder to get up in the morning, take longer to leave bed and feel less satisfied with our sleep. For some people, night awakenings may have no clear cause.</p> <p>A good way to tell if these awakenings are a problem for you is by thinking about how they affect you. When they cause feelings of frustration or worry, or are impacting how we feel and function during the day, it might be a sign to seek some help.</p> <p>We also may struggle to get up in the morning. This could be for a range of reasons, including not sleeping long enough, going to bed or waking up at irregular times – or even your own <a href="https://www.sleephealthfoundation.org.au/sleep-categories/circadian-rhythm-disorders#:%7E:text=The%20circadian%20rhythms%20throughout%20the,regulation%20of%20our%20sleeping%20patterns">internal clock</a>, which can influence the time your body prefers to sleep.</p> <p>If you’re regularly struggling to get up for work or family needs, it can be an indication you may need to seek help. Some of these factors can be explored with a sleep psychologist if they are causing concern.</p> <h2>Can my smart watch help?</h2> <p>It is important to remember sleep-tracking devices can <a href="https://www.nature.com/articles/s41746-024-01016-9">vary in accuracy</a> for looking at the different sleep stages. While they can give a rough estimate, they are not a perfect measure.</p> <p>In-laboratory <a href="https://pubmed.ncbi.nlm.nih.gov/31277862/">polysomnography</a>, or PSG, is the best standard measure to examine your sleep stages. A PSG examines breathing, oxygen saturation, brain waves and heart rate during sleep.</p> <p>Rather than closely examining nightly data (including sleep stages) from a sleep tracker, it may be more helpful to look at the patterns of your sleep (bed and wake times) over time.</p> <p><a href="https://jcsm.aasm.org/doi/10.5664/jcsm.8356">Understanding your sleep patterns</a> may help identify and adjust behaviours that negatively impact your sleep, such as your bedtime routine and sleeping environment.</p> <p>And if you find viewing your sleep data is making you feel worried about your sleep, this may not be useful for you. Most importantly, if you are concerned it is important to discuss it with your GP who can refer you to the appropriate specialist sleep health provider.<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/238069/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/amy-reynolds-424346">Amy Reynolds</a>, Associate Professor in Clinical Sleep Health, <a href="https://theconversation.com/institutions/flinders-university-972">Flinders University</a>; <a href="https://theconversation.com/profiles/claire-dunbar-1651340">Claire Dunbar</a>, Research Associate, Sleep Health, <a href="https://theconversation.com/institutions/flinders-university-972">Flinders University</a>; <a href="https://theconversation.com/profiles/gorica-micic-187159">Gorica Micic</a>, Postdoctoral Research Fellow, Clinical Psychologist, <a href="https://theconversation.com/institutions/flinders-university-972">Flinders University</a>; <a href="https://theconversation.com/profiles/hannah-scott-424633">Hannah Scott</a>, Research Fellow in Sleep Health, <a href="https://theconversation.com/institutions/flinders-university-972">Flinders University</a>, and <a href="https://theconversation.com/profiles/nicole-lovato-60684">Nicole Lovato</a>, Associate Professor, Adelaide Institute for Sleep Health, <a href="https://theconversation.com/institutions/flinders-university-972">Flinders University</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

I have a stuffy nose, how can I tell if it’s hay fever, COVID or something else?

<p><em><a href="https://theconversation.com/profiles/deryn-thompson-1449312">Deryn Thompson</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a></em></p> <p>Hay fever (also called allergic rhinitis) affects <a href="https://www.abs.gov.au/statistics/health/health-conditions-and-risks/national-health-survey-state-and-territory-findings/latest-release">24%</a> of Australians. <a href="https://www.allergy.org.au/patients/allergic-rhinitis-hay-fever-and-sinusitis/allergic-rhinitis-or-hay-fever">Symptoms</a> include sneezing, a runny nose (which may feel blocked or stuffy) and itchy eyes. People can also experience an itchy nose, throat or ears.</p> <p>But COVID is still <a href="https://theconversation.com/xec-is-now-in-australia-heres-what-we-know-about-this-hybrid-covid-variant-239292">spreading</a>, and <a href="https://theconversation.com/i-feel-sick-how-do-i-know-if-i-have-the-flu-covid-rsv-or-something-else-234266">other viruses</a> can cause cold-like symptoms. So how do you know which one you’ve got?</p> <h2>Remind me, how does hay fever cause symptoms?</h2> <p><a href="https://www.allergy.org.au/hp/papers/allergic-rhinitis-clinical-update">Hay fever</a> happens when a person has become “sensitised” to an allergen trigger. This means a person’s body is always primed to react to this trigger.</p> <p>Triggers can include allergens in the air (such as pollen from trees, grasses and flowers), mould spores, animals or house dust mites which mostly live in people’s mattresses and bedding, and feed on shed skin.</p> <p>When the body is exposed to the trigger, it produces IgE (immunoglobulin E) antibodies. These cause the release of many of the body’s own chemicals, including histamine, which result in hay fever symptoms.</p> <p>People who have asthma may find their asthma symptoms (cough, wheeze, tight chest or trouble breathing) worsen when exposed to airborne allergens. Spring and sometimes into summer can be the worst time for people with grass, tree or flower allergies.</p> <p>However, animal and house dust mite symptoms usually happen year-round.</p> <h2>What else might be causing my symptoms?</h2> <p>Hay fever does not cause a fever, sore throat, muscle aches and pains, weakness, loss of taste or smell, nor does it cause you to cough up mucus.</p> <p>These symptoms are likely to be caused by a virus, such as COVID, influenza, respiratory syncytial virus (RSV) or a “cold” (often caused by rhinoviruses). These conditions can occur all year round, with some overlap of symptoms:</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/624085/original/file-20241007-16-xf6euv.png?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/624085/original/file-20241007-16-xf6euv.png?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/624085/original/file-20241007-16-xf6euv.png?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=582&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/624085/original/file-20241007-16-xf6euv.png?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=582&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/624085/original/file-20241007-16-xf6euv.png?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=582&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/624085/original/file-20241007-16-xf6euv.png?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=731&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/624085/original/file-20241007-16-xf6euv.png?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=731&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/624085/original/file-20241007-16-xf6euv.png?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=731&amp;fit=crop&amp;dpr=3 2262w" alt="" /></a><figcaption><span class="attribution"><a class="source" href="https://theconversation.com/i-feel-sick-how-do-i-know-if-i-have-the-flu-covid-rsv-or-something-else-234266">Natasha Yates/The Conversation</a></span></figcaption></figure> <p>COVID still <a href="https://theconversation.com/xec-is-now-in-australia-heres-what-we-know-about-this-hybrid-covid-variant-239292">surrounds</a> us. <a href="https://www.sahealth.sa.gov.au/wps/wcm/connect/public+content/sa+health+internet/about+us/health+statistics/surveillance+of+notifiable+conditions/respiratory+infections+dashboard">RSV and influenza</a> rates appear higher than before the COVID pandemic, but it may be <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10888990/#:%7E:text=Increases%20in%20RSV%20patient%20volume,with%20an%20RSV%20diagnosis%20occurred">due to more testing</a>.</p> <p>So if you have a fever, sore throat, muscle aches/pains, weakness, fatigue, or are coughing up mucus, stay home and avoid mixing with others to limit transmission.</p> <p>People with COVID symptoms can take a rapid antigen test (<a href="https://www.health.gov.au/sites/default/files/2024-04/coronavirus-covid-19-rapid-antigen-tests.pdf">RAT</a>), ideally when <a href="https://www.cochrane.org/CD013705/INFECTN_how-accurate-are-rapid-antigen-tests-diagnosing-covid-19">symptoms start</a>, then isolate until symptoms disappear. <a href="https://www.mja.com.au/journal/2023/219/11/covid-19-rapid-antigen-tests-approved-self-testing-australia-published">One negative RAT alone</a> can’t rule out COVID if symptoms are still present, so test again 24–48 hours after your initial test if symptoms persist.</p> <p>You can now test yourself for COVID, RSV and influenza in a <a href="https://www.tga.gov.au/sites/default/files/2024-02/covid-19-rapid-antigen-self-tests-are-approved-australia-ifu-406813.PDF">combined RAT</a>.

Parents under fire for taking their sick toddler on a long-haul flight

<p>A couple has come under fire after documenting their experience online of boarding a long-haul flight with their toddler, despite the child being sick. </p> <p>Alina and her husband were excited to go on their long-awaited holiday to Thailand with their one-year-old son in tow, taking off on their first big family trip. </p> <p>However, shortly before they were set to take off, their child developed a raging fever, and they decided to go on the trip anyway. </p> <p>Taking the experience to social media, Alina said her son’s temperature soared to around 40 degrees, with their little boy’s condition escalating so rapidly that the parents were considering calling off their entire trip. </p> <p>“My husband and I even wanted to cancel the flight,” she confessed in the video, which has received around 1.4 million views.</p> <p>However, after realising they would be out of pocket by several thousands of dollars if they cancelled the trip at such short notice, they decided to take the risk and board the plane. </p> <p>“Our tickets would have been wasted, and the trip that cost us $3,000 would have been wasted,” the mum wrote. "One plus of this flight was that the flight was at night, and the child could sleep and recover.”</p> <p>In the clip, the parents were seen walking their son around the plane, cradling the sick toddler as he cried uncontrollably.</p> <p>Luckily, the parents “managed to bring down the temperature”, but they weren’t convinced their son would keep quiet for the rest of the trip. </p> <p>“We were so worried about how the baby would feel on an eight-hour flight,” she continued, walking the baby up and down the corridors of the airport, trying to calm him down. </p> <p>As they tried to settle the child, they realised that their hopes that he would sleep the whole way were misguided. </p> <p>“The flight turned out to be difficult,” Alina confessed. “The baby kept waking and crying.” </p> <p>In the middle of the night, their son’s fever returned, which forced the parents to “bring the temperature down again” and left them “very worried” about their son’s health. </p> <p>Their baby’s fever took a toll on the parents as well, who complained of feeling “squeezed like a lemon” while trying to keep his temperature down, as Alina recalled, “We took turns looking after the baby so each of us could sleep.”</p> <p>In a later video, the parents defended their choice to take their son on the flight despite his intense fever and blamed it on his teething, not sickness. </p> <p>“Our baby wasn’t sick, he was teething, and that’s why he had a fever,” she said. “If our child had been sick, we would have cancelled everything … I consider myself a wonderful mother.”</p> <p>Despite the mother's clarification of her son's fever, the parents were slammed for even considering taking a sick child on such a long flight. </p> <p>“It’s OK, don’t worry about making anyone else on that flight sick,” a sarcastic comment read. “This is so tremendously selfish, you are appalling for doing this to him and others.” </p> <p>“I was in the same situation,” another parent said. “I lost all bookings, but who cares, my daughter comes first always and forever, no matter the amount of money!”</p> <p>“Trips come and go; your baby’s health is priceless!” read another comment. “Forty degrees is a hospital admission! Not a flight to Thailand!”</p> <p>However, not everyone was as judgmental, with many parents extending their sympathies to the first-time parents, as one person wrote, “You know what’s best for your baby. Everyone will say things. But only you will know when you are in that situation.”</p> <p>“Everyone is a first-time parent,” another defended. “This was a lesson learned. A baby’s health is of utmost importance. No holiday is more important than that. I hope he is OK now.”</p> <p><em>Image credits: TikTok</em></p>

Heading to Bali or somewhere tropical these holidays? Here’s what you need to know about dengue fever

<p><em><a href="https://theconversation.com/profiles/cameron-webb-6736">Cameron Webb</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>If you’re looking to escape the Australian winter for your next holiday, don’t forget where there’s warmth, there will also be mosquitoes.</p> <p>In turn, tropical destinations can be hot spots of mosquito-borne diseases such as dengue. In fact, Australian health authorities have warned travellers to Bali <a href="https://www.health.wa.gov.au/Media-releases/2024/May/Dengue-fever-warning-for-Western-Australian-travellers">to be aware</a> of the risk of dengue, with cases surging in the region.</p> <p>So here’s how to protect yourself and your family on holidays.</p> <h2>What is dengue?</h2> <p><a href="https://www.who.int/news-room/fact-sheets/detail/dengue-and-severe-dengue">Dengue virus infection</a> (commonly known as dengue fever, or just dengue) is caused by viruses spread by the bite of a mosquito. The mosquito species that typically transmit dengue are <em>Aedes aegypti</em> and <em>Aedes albopictus</em>.</p> <p>There are four strains of dengue virus. Each has the potential to cause illness that can range from <a href="https://www.cdc.gov/dengue/signs-symptoms/index.html">mild to severe and potentially life threatening</a>.</p> <p>Symptoms <a href="https://www.health.nsw.gov.au/Infectious/factsheets/Pages/dengue.aspx">typically include</a> rash, fever, chills, headache, muscle and joint pain, and fatigue. People also often report abdominal pain, nausea and vomiting.</p> <p>While infection with just one of these viruses can make you sick, subsequent exposure to other strains can have more <a href="https://theconversation.com/explainer-what-are-antibodies-and-why-are-viruses-like-dengue-worse-the-second-time-68227">serious health implications</a>. In these cases, symptoms can also include the presence of blood in vomit, bleeding gums and breathing difficulties.</p> <p>Dengue infection must be confirmed via a blood test, but there are <a href="https://www.healthdirect.gov.au/dengue-fever">no specific treatments</a>. Most people will recover on their own however <a href="https://www.cdc.gov/dengue/treatment/index.html">staying hydrated is crucial</a> and pain relief can help with symptoms. If more severe illness occurs, seek urgent medical care.</p> <h2>Are travellers at risk?</h2> <p>The disease is now endemic in around 100 countries and <a href="https://www.cdc.gov/dengue/areas-with-risk/index.html">an estimated 4 billion people</a> are considered at risk. Asian countries represent <a href="https://www.who.int/news-room/fact-sheets/detail/dengue-and-severe-dengue">around 70%</a> of the global disease burden. Even <a href="https://theconversation.com/how-the-paris-olympics-could-become-a-super-spreader-event-for-dengue-231853">Europe is at risk</a>.</p> <p><a href="https://www.who.int/emergencies/disease-outbreak-news/item/2023-DON498">One of the worst years</a> on record was 2023, but the burden of dengue continues to grow. In the first four months of 2024, Indonesia reported <a href="https://www.who.int/emergencies/disease-outbreak-news/item/2024-DON518">three times as many cases</a> of dengue compared to the same period in 2023.</p> <p>Dengue is not a new risk to Australian travellers. Before COVID disrupted international travel, the number of Australians returning from tropical destinations with dengue <a href="https://europepmc.org/article/med/23692160">was steadily increasing</a>.</p> <p>For example, between 2010 and 2016, there was an average <a href="https://www.mdpi.com/2414-6366/3/1/9">annual increase of 22%</a> of travellers returning to Victoria with dengue. Almost half of these people contracted the illness in Indonesia. Bali is well documented as posing <a href="https://academic.oup.com/jtm/article/25/1/tay061/5065180?login=false">a risk of dengue</a> to travellers.</p> <p>International travel restrictions due to COVID <a href="https://academic.oup.com/jtm/article/31/2/taae014/7577676">abruptly stopped this trend</a>. But now Australians are again embracing international travel, <a href="https://www.dailymail.co.uk/news/article-13303747/Worrying-reason-Aussie-travellers-Bali-coming-sick.html">cases are rising once more</a>.</p> <p>Bali isn’t the only destination with <a href="https://www.washingtonpost.com/health/2024/06/30/dengue-puerto-rico-mosquito-climate-change/">a surge in dengue</a>, but we know it’s a popular holiday destination for Australian travellers. There’s little doubt plenty of families will be heading to Bali these school holidays.</p> <h2>How about the risk in Australia?</h2> <p>Not all mosquitoes can spread dengue viruses. This is why the risk is different in Bali and other tropical regions compared to Australia.</p> <p>Although there are more than 40 Australian mosquito species known or suspected to be transmitting local pathogens, such as <a href="https://journals.plos.org/plospathogens/article?id=10.1371/journal.ppat.1005070">Ross River virus</a>, Australia is generally free of local dengue risk due to the limited spread of <em>Aedes aegypti</em> and <em>Aedes albopictus</em>.</p> <p>While <em>Aedes aegypti</em> is found in <a href="https://www.health.qld.gov.au/clinical-practice/guidelines-procedures/diseases-infection/diseases/mosquito-borne/dengue/virus-fever">parts of Queensland</a>, thanks to interventions by the <a href="https://www.worldmosquitoprogram.org/en/global-progress/australia/cairns-and-surrounds">World Mosquito Program</a> and local authorities dengue risk is low. These interventions include the release of laboratory-bred mosquitoes that prevent mosquitoes in the environment <a href="https://www.worldmosquitoprogram.org/en/work/wolbachia-method">spreading viruses</a>, as well as <a href="https://www.sciencedirect.com/science/article/pii/S2221169115309096">community education</a>. But <a href="https://theconversation.com/after-decades-away-dengue-returns-to-central-queensland-117821">local cases</a> occasionally occur.</p> <p><em>Aedes albopictus</em> is not currently found <a href="https://theconversation.com/how-we-kept-disease-spreading-asian-tiger-mozzies-away-from-the-australian-mainland-72873">on the Australian mainland</a> but is present in the islands of the Torres Strait. A dengue outbreak <a href="https://www.torres-cape.health.qld.gov.au/about-us/news/further-cases-of-dengue-fever-on-mer">has occurred</a> there this year.</p> <h2>Keep mozzies away during the day, not just at night</h2> <p>While there is a vaccine available, it’s not recommended for <a href="https://onlinelibrary.wiley.com/doi/full/10.5694/mja2.50471">short-term travellers</a>. There are <a href="https://www.health.gov.au/resources/publications/atagi-advice-on-the-use-of-dengvaxiar-for-australians">strict eligibility criteria</a> for its use, so speak to a health professional for advice.</p> <p>For the majority of travellers, preventing mosquito bites is the only way to prevent disease.</p> <p>But there are differences in the behaviour of dengue mosquitoes that mean the normal measures to avoid mosquito bites may not be as effective.</p> <p>During the Australian summer, mosquitoes found in local wetlands can be <a href="https://theconversation.com/the-worst-year-for-mosquitoes-ever-heres-how-we-find-out-68433">incredibly abundant</a>. We tend to need to reach for the repellent and cover up to stop bites as soon as the sun starts going down.</p> <p><em>Aedes aegypti</em> and <em>Aedes albopictus</em> <a href="https://journals.plos.org/plosntds/article?id=10.1371/journal.pntd.0010818">can aggressively bite people</a> but they’re not as abundant as the swarms of summer mosquitoes back home.</p> <p>They also bite during the day, not just at night. So for those travelling to Bali or other areas at risk of dengue, putting insect repellent on <a href="https://www.smartraveller.gov.au/news-and-updates/global-dengue-fever-outbreaks">throughout the day</a> is recommended.</p> <h2>What to pack for protection</h2> <p>If you’re staying in a major resort, there’s likely to be a mosquito control program in place. This may include minimising available water for mosquito breeding in combination with insecticide use. Mosquitoes are also less likely to be an issue in air-conditioned accommodation.</p> <p>But if you’re planning to spend time out and about visiting local villages, markets, or in nature, it’s best to protect against bites.</p> <p>Light coloured and <a href="https://www.health.wa.gov.au/Media-releases/2024/May/Dengue-fever-warning-for-Western-Australian-travellers">loose fitting clothing</a> will help stop mosquito bites (and help keep you cool). Covered shoes can help too – dengue mosquitoes <a href="https://www.npr.org/sections/goatsandsoda/2016/02/22/465594861/why-zika-spreading-mosquitoes-love-ankles">love smelly feet</a>.</p> <p>Finally, it’s best to take some insect repellent with you. There may not be any available at your destination, and formulations on sale might not have been through the same thorough testing as products <a href="https://www.apvma.gov.au/">approved in Australia</a>.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/233670/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/cameron-webb-6736"><em>Cameron Webb</em></a><em>, Clinical Associate Professor and Principal Hospital Scientist, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Still fab after 60 years: how The Beatles’ A Hard Day’s Night made pop cinema history

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/alison-blair-223267">Alison Blair</a>, <a href="https://theconversation.com/institutions/university-of-otago-1304">University of Otago</a></em></p> <p>I first saw A Hard Day’s Night at a film festival over 20 years ago, at the insistence of my mum. By then, it was already decades old, but I remember being enthralled by its high-spirited energy.</p> <p>A Beatles fan, mum had introduced me to the band’s records in my childhood. At home, we listened to Please Please Me, the band’s 1963 single, and the Rubber Soul album from 1965, which I loved.</p> <p>Television regularly showed old black-and-white scenes of Beatlemania that, to a ten-year-old in the neon-lit 1980s, seemed like ancient history. But then, I’d never seen a full-length Beatles film. I had no idea what I was in for.</p> <p>When the lights went down at Dunedin’s Regent Theatre, the opening chord of the film’s title song announced its intentions: an explosion of youthful vitality, rhythmic visuals, comical high jinks and the electrifying thrill of Beatlemania in 1964.</p> <p>This time, it didn’t seem ancient at all.</p> <p>Since that first viewing, I’ve returned to A Hard Day’s Night again and again. I now show it to my students as a historically significant example of pop music film making – visually inventive cinema, emblematic of a fresh era in youth culture, popular music and fandom.</p> <h2>Beatlemania on celluloid</h2> <p>A musical comedy depicting a chaotic 36 hours in the life of the Beatles, A Hard Day’s Night has now reached its 60th anniversary.</p> <p>Directed by <a href="https://www.imdb.com/name/nm0504513/">Richard Lester</a>, the film premiered in London on July 6 1964, with its first public screening a day later (incidentally, also Ringo Starr’s birthday), and the <a href="https://www.discogs.com/master/24003-The-Beatles-A-Hard-Days-Night">album of the same name</a> released on July 10.</p> <p>The band’s popularity was by then reaching dizzying heights of hysteria, all reflected in the film. The Beatles are chased by hordes of fans, take a train trip, appear on TV, run from the police in a Keystone Cops-style sequence, and play a televised concert in front of screaming real-life Beatles fans.</p> <p>Side one of the album provides the soundtrack, and the film inspired pop music film and video from then on, from the <a href="https://www.imdb.com/title/tt0060010/">Monkees TV series</a> (1966–68) to the Spice Girls’ <a href="https://www.imdb.com/title/tt0120185/">Spice World</a> (1997) and music videos as we know them today.</p> <h2>The original music video</h2> <p>Postwar teen culture and consumerism had been on the rise since the 1950s. In 1960s Britain, youth music TV programmes, notably <a href="https://www.imdb.com/title/tt0196287/">Ready Steady Go!</a> (1963–66), meant pop music now had a developing visual culture.</p> <p>The youthful zest and vitality of ‘60s London was reflected in the pop-cultural sensibility, modern satirical humour and crisp visual impact of A Hard Day’s Night.</p> <p>Influenced by <a href="https://nofilmschool.com/french-new-wave-cinema">French New Wave</a> film making, and particularly the early 1960s work of <a href="https://www.imdb.com/name/nm0000419/">Jean-Luc Godard</a>, A Hard Day’s Night employs <em><a href="https://indiefilmhustle.com/cinema-verite/">cinéma vérité</a></em>-style hand-held cinematography, brisk jump cuts, unusual framing and dynamic angles, high-spirited action, and a self-referential nonchalance.</p> <p>The film also breaks the “fourth wall”, with characters directly addressing the audience in closeup, and reveals the apparatus of the visual performance of music: cameras and TV monitors are all part of the frame.</p> <p>Cutting the shots to the beat of the music – as in the Can’t Buy Me Love sequence – lends a visual rhythm that would later become the norm in music video editing. Lester developed this technique further in the second Beatles film, <a href="https://www.imdb.com/title/tt0059260/">Help!</a> (1965).</p> <p>The closing sequence of A Hard Day’s Night is possibly the film’s most dynamic: photographic images of the band edited to the beat in the style of stop-motion animation. Sixty years on, it still feels fresh, especially as so much contemporary film making remains hidebound by formulaic Hollywood rules.</p> <figure class="align-center "><img src="https://images.theconversation.com/files/604790/original/file-20240704-17-ov77mn.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/604790/original/file-20240704-17-ov77mn.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=453&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/604790/original/file-20240704-17-ov77mn.jpg?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=453&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/604790/original/file-20240704-17-ov77mn.jpg?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=453&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/604790/original/file-20240704-17-ov77mn.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=569&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/604790/original/file-20240704-17-ov77mn.jpg?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=569&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/604790/original/file-20240704-17-ov77mn.jpg?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=569&amp;fit=crop&amp;dpr=3 2262w" alt="A Hard Day's Night movie poster" /><figcaption><span class="caption">A new pop aesthetic: original film poster for A Hard Day’s Night.</span> <span class="attribution"><span class="source">Getty Images</span></span></figcaption></figure> <h2>Slapstick and class awareness</h2> <p>As with much popular culture from the past, the humour in A Hard Day’s Night doesn’t always doesn’t land the way it would have in 1964. And yet, there are moments that seem surprisingly modern in their razor-sharp irony.</p> <p>In particular, the band’s Liverpudlian working-class-lad jibes and chaotic energy contrast brilliantly with the film’s upper-class characters. Actor Victor Spinetti’s comically over-anxious TV director, constantly hand-wringing over the boys’ rebelliousness, underscores the era-defining change the Beatles represented.</p> <p>Corporate pop-culture consumerism is also satirised. John Lennon “snorts” from a Coca-Cola bottle, a moment so knowingly silly it registers as more contemporary than it really is. George Harrison deflects a journalist’s banal questions with scathingly witty answers, and cuts a fashion company down to size by describing their shirt designs as “grotesque”.</p> <p>And there is Paul McCartney’s running joke that his grandfather – played by Wilfred Brambell from groundbreaking sitcom <a href="https://www.imdb.com/title/tt0057785/">Steptoe and Son</a> (1962–74) – is “very clean”.</p> <p>Even the film’s old-fashioned visual slapstick still holds up in 2024. Showing the film to this year’s students, I didn’t expect quite as much laughter when Ringo’s attempts to be chivalrous result in a fall-down-a-hole mishap.</p> <p>In 2022, the <a href="https://www.criterion.com/">Criterion Collection</a> released a high-resolution restoration of the film, so today A Hard Day’s Night can be seen in all its fresh, black-and-white, youthful vigour.</p> <p>Happy 60th, A Hard Day’s Night. And happy 84th, Ringo. Both still as lively and energetic as ever.<!-- Below is The Conversation's page counter tag.

10 tips for a better night’s sleep in a hotel room

<p>From noisy neighbours to unbearable bedding, a good night’s sleep in a hotel room can be hard to come by. Here are 10 tips to help you get decent shut eye.</p> <p><strong>1. Book a room midway down a hallway</strong></p> <p>This is generally the quietest part of the floor, way from ice and wending machines, laundry facilities, exits, closets and any other places where sudden noises might occur.</p> <p><strong>2. Try to avoid rooms facing a pool</strong></p> <p>While the view is something to admire, pools can also be the sight of noise generating late-night gathering and any sounds generally echo loudly off the water.</p> <p><strong>3. Inquire at the front desk about pillow options</strong></p> <p>If the wrong pillow gives you back or neck pain have a chat to the front desk when checking in. Most hotels stock pillows of varying firmness, and can offer a better fit.</p> <p><strong>4. Pack earplugs and eyeshades</strong></p> <p>When you’re struggling to get to sleep the tiniest noise or ray of light can end up being a huge distraction. Nip this in the bud by packing earplugs and eyeshades.</p> <p><strong>5. Turn your mobile phone off</strong></p> <p>Mobile notifications can be a huge distraction (particularly when they’re coming from friends and family in different time zones). Turn your phone off, and enjoy the bliss. </p> <p><strong>6. Make use of your ‘do not disturb’ sign</strong></p> <p>If you’re planning to sleep in make sure you put your ‘do not disturb’ sign on the outside doorknob, otherwise you might get a rude awakening from a housekeeper.</p> <p><strong>7. Report any noises immediately</strong></p> <p>Sometimes a quick pound of the wall will quiet down a noisy neighbour, but this doesn’t always work. If the people in the room next to you won’t keep quiet, make sure you let the front desk know and they can take the necessary actions.</p> <p><strong>8. Adjust the room temperature</strong></p> <p>Most people sleep better in a cooler room, so make sure you adjust the temperature to whatever is the best fit for you to get sleep. Even just opening the window a tiny little crack can make a big difference in terms of your overall comfort levels.</p> <p><strong>9. Ask the front desk about blackout shades</strong></p> <p>Particularly if you’re staying in a city that’s full of lights, noises and distractions, blackout shades can provide you with a level of peace and comfort that will help you sleep.</p> <p><strong>10. Consider bringing your own sheets</strong></p> <p>Particularly if you’ve got skin sensitives, it’s generally a good idea to bring your own sheets (if you’ve got enough space). The familiar scent and feel will really help you sleep.</p> <p><em>Image credits: Shutterstock</em></p>

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

<p><em><a href="https://theconversation.com/profiles/christian-moro-121754">Christian Moro</a>, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a> and <a href="https://theconversation.com/profiles/charlotte-phelps-1187658">Charlotte Phelps</a>, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a></em></p> <p>It can be normal to wake up once or even twice during the night to wee, especially as we get older.</p> <p>One in three adults over 30 makes <a href="https://pubmed.ncbi.nlm.nih.gov/30085529">at least two</a> trips to the bathroom every night.</p> <p>Waking up from sleep to urinate on a regular basis is called <a href="https://www.ncbi.nlm.nih.gov/books/NBK518987/">nocturia</a>. It’s one of the most commonly reported <a href="https://pubmed.ncbi.nlm.nih.gov/32249998/">bothersome urinary symptoms</a> (others include urgency and poor stream).</p> <p>So what causes nocturia, and how can it affect wellbeing?</p> <h2>A range of causes</h2> <p>Nocturia can be caused by a variety of <a href="https://www.health.gov.au/sites/default/files/nocturia-going-to-the-toilet-at-night_0.pdf">medical conditions</a>, such as heart or kidney problems, poorly controlled diabetes, bladder infections, an <a href="https://www.nature.com/articles/s41598-023-44916-8">overactive bladder</a>, or gastrointestinal issues. Other causes include pregnancy, <a href="https://onlinelibrary.wiley.com/doi/10.1002/nau.24839">medications</a> and consumption of alcohol or caffeine before bed.</p> <p>While nocturia causes disrupted sleep, the reverse is true as well. Having broken sleep, or <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4055528/">insomnia</a>, can also cause nocturia.</p> <p>When we sleep, an antidiuretic hormone is released that slows down the rate at which our <a href="https://theconversation.com/is-urine-sterile-do-urine-therapies-work-experts-debunk-common-pee-myths-191862">kidneys produce urine</a>. If we lie awake at night, less of this hormone <a href="https://journals.physiology.org/doi/full/10.1152/ajprenal.00025.2023">is released</a>, meaning we continue to produce normal rates of urine. This can accelerate the rate at which we fill our bladder and need to get up during the night.</p> <p>Stress, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4153377/">anxiety</a> and watching television <a href="https://www.ncbi.nlm.nih.gov/books/NBK518987">late into the night</a> are common causes of insomnia.</p> <h2>Effects of nocturia on daily functioning</h2> <p>The recommended amount of sleep for adults is between <a href="https://www.nhlbi.nih.gov/health/sleep/how-much-sleep">seven and nine hours</a> per night. The more times you have to get up in the night to go to the bathroom, the more this impacts <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3602727/#:%7E:text=Nocturia%20is%2C%20however%2C%20an%20important,(QoL)%20and%20general%20health.">sleep quantity and quality</a>.</p> <p>Decreased sleep can result in increased <a href="https://hqlo.biomedcentral.com/articles/10.1186/s12955-019-1251-5">tiredness</a> during the day, poor concentration, forgetfulness, changes in mood and impaired <a href="https://pubmed.ncbi.nlm.nih.gov/28425062/">work performance</a>.</p> <p>If you’re missing out on quality sleep due to nighttime trips to the bathroom, this can affect your quality of life.</p> <p>In more severe cases, nocturia has been compared to having a similar impact on <a href="https://www.racgp.org.au/getattachment/b43c05ba-e29e-47c3-b816-ec47ceeafe97/Nocturia-a-guide-to-assessment-and-management.aspx">quality of life</a> as diabetes, high blood pressure, chest pain, and some forms of arthritis. Also, frequent disruptions to quality and quantity of sleep can have longer-term health impacts.</p> <p>Nocturia not only upsets sleep, but also increases the risk of <a href="https://www.auajournals.org/doi/10.1097/JU.0000000000000459">falls</a> from moving around in the dark to go to the bathroom.</p> <p>Further, it can affect sleep partners or others in the household who may be disturbed when you get out of bed.</p> <h2>Can you have a ‘small bladder’?</h2> <p>It’s a common misconception that your trips to the bathroom are correlated with the size of your bladder. It’s also unlikely your bladder is <a href="https://youtu.be/blVmyrBPves">smaller</a> relative to your other organs.</p> <p>If you find you are having to wee more than your friends, this could be due to body size. A smaller person drinking the same amount of fluids as someone larger will simply need to go the bathroom more often.</p> <figure><iframe src="https://www.youtube.com/embed/blVmyrBPves?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">Can you have a small bladder?</span></figcaption></figure> <p>If you find you are going to the bathroom quite a lot during the day and evening (<a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5903463/">more than eight times</a> in 24 hours), this could be a symptom of an overactive bladder. This often presents as frequent and sudden urges to urinate.</p> <p>If you are concerned about any lower urinary tract symptoms, it’s worth having a chat with your family GP.</p> <p>There are some medications that can assist in the management of nocturia, and your doctor will also be able to help identify any underlying causes of needing to go to the toilet during the night.</p> <h2>A happy and healthy bladder</h2> <p>Here are some tips to maintain a happy and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3206217/">healthy</a> bladder, and reduce the risk you’ll be up at night:</p> <ul> <li> <p>make your <a href="https://theconversation.com/what-position-should-i-sleep-in-and-is-there-a-right-way-to-sleep-189873">sleep environment comfortable</a>, with a suitable mattress and sheets to suit the temperature</p> </li> <li> <p>get to bed early, and limit <a href="https://www.ncbi.nlm.nih.gov/books/NBK518987/">screens</a>, or activites before bed</p> </li> <li> <p>limit foods and drinks that irritate the bladder, such as <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9811496/">coffee or alcohol</a>, especially before bedtime</p> </li> <li> <p>sit in a <a href="https://theconversation.com/does-it-matter-if-you-sit-or-stand-to-pee-and-what-about-peeing-in-the-shower-206869">relaxed position</a> when urinating, and allow time for the bladder to completely empty</p> </li> <li> <p>practice <a href="https://www.continence.org.au/about-continence/continence-health/pelvic-floor">pelvic floor muscle exercises</a></p> </li> <li> <p>drink an adequate amount of fluids during the day, and avoid becoming <a href="https://www.health.gov.au/sites/default/files/nocturia-going-to-the-toilet-at-night_0.pdf">dehydrated</a></p> </li> <li> <p>maintain a healthy lifestyle, eat <a href="https://journals.physiology.org/doi/full/10.1152/advan.00052.2023">nutritious foods</a> and do not do anything harmful to the body such as smoking or using illicit drugs</p> </li> <li> <p>review your medications, as the time you take some <a href="https://www.health.gov.au/sites/default/files/nocturia-going-to-the-toilet-at-night_0.pdf">pharmaceuticals</a> may affect urine production or sleep</p> </li> <li> <p>if you have <a href="https://pubmed.ncbi.nlm.nih.gov/28675633/">swollen legs</a>, raise them a few hours before bedtime to let the <a href="https://www.racgp.org.au/afp/2012/june/nocturia-a-guide-to-assessment-and-management">fluid drain</a>.<!-- Below is The Conversation's page counter tag.

Hello hay fever – why pressing under your nose could stop a sneeze but why you shouldn’t

<p><em><a href="https://theconversation.com/profiles/theresa-larkin-952095">Theresa Larkin</a>, <a href="https://theconversation.com/institutions/university-of-wollongong-711">University of Wollongong</a> and <a href="https://theconversation.com/profiles/jessica-nealon-1481995">Jessica Nealon</a>, <a href="https://theconversation.com/institutions/university-of-wollongong-711">University of Wollongong</a></em></p> <p>If you have <a href="https://theconversation.com/sniffles-sneezing-and-cough-how-to-tell-if-its-a-simple-allergy-rather-than-the-virus-139657">hay fever</a>, you’ve probably been sneezing a lot lately.</p> <p>Sneezing is universal but also quite unique to each of us. It is a protective reflex action outside our conscious control, to remove irritants from inside our nose.</p> <p>The <a href="https://www.healthline.com/health/holding-in-a-sneeze">pressure in the airways</a> during a sneeze is more than 30 times greater than heavy breathing during exercise. Estimates of how fast a sneeze travels range from <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0059970">5 metres a second</a> to <a href="https://pubmed.ncbi.nlm.nih.gov/19617285/">more than 150 kilometres per hour</a>.</p> <p>You can sometimes stop a sneeze by holding your nose or pressing underneath it. This is related to the <a href="https://www.sciencedirect.com/topics/medicine-and-dentistry/gate-control-theory">gate control theory of pain</a> and the idea you can change neural responses with external stimulation. But given the velocity of a sneeze, it might not be a good idea to stop it after it has started.</p> <h2>An involuntary reflex</h2> <p>A sneeze is initiated when sensory nerves in our nose are <a href="https://journals.sagepub.com/doi/10.1177/1753465809340571?url_ver=Z39.88-2003&amp;rfr_id=ori:rid:crossref.org&amp;rfr_dat=cr_pub%20%200pubmed">stimulated by an irritant</a> such as allergens, viruses, bacteria or even fluid.</p> <p>The sensory nerves then carry this irritant information to the brain.</p> <p>When a threshold amount of irritant signals reach the brain, the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2077498/">sneeze reflex is triggered</a>. A sneeze first involves a deep intake of breath and a <a href="https://www.scientificamerican.com/article/why-do-we-sneeze/">build-up of pressure inside the airways</a>. This is then followed by <a href="https://www.healthline.com/health/back-pain/back-pain-when-sneezing#sneezing-as-a-cause">contraction of the diaphragm</a> and rib muscles, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2077498/">reflex closing of the eyes</a> and a strong exhalation.</p> <p>These are the “ah” and the “tchoo” phases of a sneeze.</p> <p>On the exhalation of a sneeze, your tongue is lifted to the roof of your mouth. This <a href="https://www.atsjournals.org/doi/10.1164/rccm.202004-1263PP">closes off the back of the mouth</a> so the air is forced mostly through your nose. The air expelled through the nose flushes out the irritants that caused the sneeze.

The interneurons are the “gates” of the <a href="https://www.physio-pedia.com/Gate_Control_Theory_of_Pain#:%7E:text=and%20trigger%20%E2%80%A2-,Introduction,be%20let%20through%20or%20restricted.">gate control theory of pain</a>.</p> <p>A nerve carrying a pain signal tells the interneuron to “open the gate” for the pain signal to reach the brain.

These actions can stimulate the trigeminal touch nerves and reduce pain signals via the gate control mechanism.</p> <h2>So does putting your finger under your nose stop a sneeze?</h2> <p>There are <a href="https://www.healthline.com/health/how-to-stop-sneezing">many suggestions</a> of how to stop a sneeze. These include pulling your ear, putting your tongue to the roof of your mouth or the back of your teeth, touching your nose, or even sticking your finger in your nose.</p> <p>All of these stimulate the trigeminal touch nerves with the goal of telling the interneurons to “close the gate”.

All the reasons you might be having night sweats – and when to see a doctor

<p><em><a href="https://theconversation.com/profiles/siobhan-banks-18473">Siobhan Banks</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a> and <a href="https://theconversation.com/profiles/linda-grosser-1461631">Linda Grosser</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a></em></p> <p>You’ve finished a workout, so you’re hot and drenched with perspiration – but soon you begin to feel cool again. Later, it’s a sweltering summer evening and you’re finding it hard to sleep, so you kick off the covers.</p> <p>Sweating is a normal part of the body’s cooling system, helping to release heat and maintain optimal body temperature. But regularly waking up during the night, soaked through from excessive sweating is not.</p> <p>Night sweats are <a href="https://www.mayoclinic.org/symptoms/night-sweats/basics/definition/sym-20050768">repeated episodes</a> of excessive or intense sweating at night. They are an unpleasant part of life for many people.</p> <p>Many conditions and factors can trigger night sweats by changing the body’s tightly regulated temperature set point, at which the body attempts to maintain its <a href="https://www.tandfonline.com/doi/full/10.4161/temp.29702">core temperature</a>. Some triggers are harmless (a hot bedroom) or even related to positive lifestyle changes (exercise). Others have an underlying cause like menopause, infection, disease or medication.</p> <h2>Temperature control and sweating</h2> <p>The hypothalamus, located in the brain, is part of the <a href="https://www.hormones-australia.org.au/the-endocrine-system/">endocrine system</a> and the temperature control centre for the body. It contains <a href="https://www.statpearls.com/point-of-care/29920#ref_19631766">temperature sensors</a> that receive information from nerve cells (thermoreceptors) located centrally (in the organs) and peripherally in the skin.</p> <p>Thermoreceptors detect changes in body temperature, sending signals back to the hypothalamus. These <a href="https://www.sciencedirect.com/science/article/pii/S1876034111000256">signals</a> will either activate sweating to cool the body or shivering to warm the body.</p> <h2>Hormones and night sweats</h2> <p>Anyone, regardless of age or gender, can experience night sweats. But women experience night sweats more often than men, largely because menopause and associated changing hormone levels are <a href="https://www.tandfonline.com/doi/abs/10.3109/13697137.2011.608596">a leading cause</a>.</p> <p>Approximately 80% of women experience <a href="https://link.springer.com/article/10.1007/s00737-007-0209-5">hot flashes</a> (also called hot flushes) or night sweats after <a href="https://www.menopause.org.au/hp/information-sheets/what-is-menopause">menopause</a> (when periods have ceased for 12 months) and during <a href="https://www.healthdirect.gov.au/perimenopause">perimenopause</a> (the time leading up to it).</p> <p>While both hot flashes and night sweats produce a feeling of overheating, they are different experiences associated with menopause. Hot flashes occur during the day, are transient episodes of flushing and may involve sweating. Night sweats occur at night and involve an intense period of <a href="https://www.proquest.com/docview/2821423865?accountid=14649">sweating</a>. Changing oestrogen levels are thought to impact norepinephrine and serotonin levels, two neurotransmitters that influence <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6459071/#:%7E:text=%5B21%5D%20Estrogens%20stimulate%20the%20production,norepinephrine%20which%20disturbs%20hypothalamic%20thermostat">temperature regulation</a> in the hypothalamus.</p> <p>Hormones also influence night sweats in men, particularly those with low <a href="https://www.healthdirect.gov.au/testosterone">testosterone</a> levels, known as <a href="https://www.hormones-australia.org.au/endocrine-diseases/hypogonadism/">hypogonadism</a>. Around 38% of men aged 45 years or older have low testosterone <a href="https://www.scielo.br/j/ibju/a/RZqqfTn5tY6BFpV6rp3GMxJ/">levels</a> but it can affect men at any age.</p> <h2>Infections, disease and medications</h2> <p>When fighting infection, our body temperature often <a href="https://europepmc.org/article/nbk/nbk562334">rises</a>. This can stimulate sweating to cool and decrease body <a href="https://www.sciencedirect.com/science/article/pii/S1876034111000256">temperature</a>.</p> <p>Minor infections like the common cold can cause night sweats. They are also a symptom of serious infections such as human immunodeficiency virus (HIV) and diseases such as <a href="https://www.aafp.org/pubs/afp/issues/2020/0101/p34.html">Hodgkin’s</a> and <a href="https://link.springer.com/article/10.2165/00002018-200831020-00002">non-Hodgkin’s lymphoma</a>. However, night sweats are rarely the only symptom present.</p> <p>Medications such as selective serotonin reuptake inhibitors (SSRIs), corticosteroids, thyroid hormone replacement and methadone can cause night sweats. These medications affect parts of the <a href="https://link.springer.com/article/10.2165/00002018-200831020-00002">brain</a> and neurotransmitters that control and stimulate sweating.</p> <p>Regular alcohol (particularly alcohol dependence) and recreational drug use can also <a href="https://link.springer.com/article/10.2165/00002018-200831020-00002">increase the risk</a> of night sweats.</p> <h2>Stress, snoring and strenuous exercise</h2> <p>Night sweats are commonly reported by people with <a href="https://karger.com/spp/article-abstract/26/2/92/295722/Psychological-Sweating-A-Systematic-Review-Focused?redirectedFrom=fulltext">anxiety</a>.</p> <p>Psychological stress activates the body’s fight or flight system releasing neurotransmitters that increase heart rate, respiration, and blood pressure. This causes the body to heat up, at which point it starts sweating to cool the body back down. Night sweats may also increase anxiety, causing more sweating which in turn leads to less sleep and more anxiety.</p> <p>If anxiety causes night sweats and this causes distress, it’s best to get up, move around and engage in a <a href="https://www.calmclinic.com/anxiety/symptoms/night-sweats">calming routine</a>, preferably in a dark or dimly lit room.</p> <p>Night sweats have similarly been connected with sleep disorders like <a href="https://www.healthdirect.gov.au/obstructive-sleep-apnoea">obstructive sleep apnoea</a>, where the airway is repeatedly blocked during sleep and there is loud snoring. About one third of people with obstructive sleep apnoea regularly <a href="https://link.springer.com/article/10.1007/s11325-011-0502-4">experience night sweats</a>. The exact cause is undetermined but research shows it is linked with low blood oxygen levels (<a href="https://link.springer.com/article/10.1007/s11325-022-02701-3">hypoxemia</a>) and/or <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/j.1365-2869.2009.00743.x">high blood pressure</a>.</p> <p>People can experience night sweats after high-intensity workouts. Vigorous exercise can stimulate the thyroid, <a href="https://www.ncbi.nlm.nih.gov/books/NBK500006/#:%7E:text=Thyroid%20hormone%20increases%20the%20basal,respiration%20rate%2C%20and%20body%20temperature">increasing basal metabolic rate</a> and body temperature for up to <a href="https://journals.lww.com/acsm-msse/Fulltext/2011/09000/A_45_Minute_Vigorous_Exercise_Bout_Increases.6.aspx">14 hours post exercise</a>. So night sweats can occur even after a vigorous morning workout.</p> <p>Night sweats can indicate overtraining and/or under-fuelling. If not enough calories are consumed to support the increase in training, blood sugar could drop and you could experience <a href="https://www.aafp.org/pubs/afp/issues/2003/0301/p1019.pdf">hypoglycaemia</a>, which can cause night sweats.</p> <h2>When to seek help and 5 things to try</h2> <p>There are <a href="https://www.aafp.org/pubs/afp/issues/2020/1001/p427.html">numerous</a> health conditions and medications that can cause night sweats and interfere with sleep.</p> <p>If night sweats are regular, distressing, interfere with sleep or are accompanied by symptoms such as fatigue or weight loss (not related to lifestyle or diet changes) talk to a doctor to help determine the cause. They might suggest alternative medications to any you’re taking or recommend tests or investigations.</p> <p>In the meantime, you can try the following ideas:</p> <p><strong>1.</strong> sleep in a cool room and use a fan if needed</p> <p><strong>2.</strong> don’t overdress for bed. Wear breathable cotton or linen pyjamas</p> <p><strong>3.</strong> choose lightweight bedding you can kick off.

How do hay fever treatments actually work? And what’s best for my symptoms?

<p><em><a href="https://theconversation.com/profiles/mary-bushell-919262">Mary Bushell</a>, <a href="https://theconversation.com/institutions/university-of-canberra-865">University of Canberra</a></em></p> <p>Spring has sprung and many people are welcoming longer days and more time outdoors. But for <a href="https://www.aihw.gov.au/reports/chronic-respiratory-conditions/allergic-rhinitis-hay-fever/contents/allergic-rhinitis">almost one in five Australians</a>, spring also brings the misery of watery, itchy red eyes, a runny, congested nose, and sneezing.</p> <p>Hay fever (also known as allergic rhinitis) is caused when an allergen enters the nose or eyes. Allergens are harmless airborne substances the body has incorrectly identified as harmful. This triggers an immune response, which leads to the release of inflammatory chemicals (mediators) – one of which is histamine.</p> <p>Allergens that trigger hay fever differ from person to person. Common seasonal allergens include tree, grass and weed pollens (year-round allergens include dust mites, mould and pet dander). It’s now <a href="https://www.sciencedirect.com/science/article/pii/S132602002302191X">pollen season</a> in many parts of Australia, with pollen counts at their highest and hay fever cases surging.</p> <p>So what medicines can prevent or reduce hay fever symptoms, and how do they work?</p> <h2>Antihistamines</h2> <p>Knowing the release of histamine is a cause of hay fever symptoms, it’s unsurprising that <em>anti</em>-histamines are one of the most frequently recommended medicines to treat hay fever.</p> <p>Antihistamines block histamine from binding to histamine receptors in the body and having an effect, reducing symptoms.</p> <p>In Australia, we broadly have two types. The older sedating (introduced in the <a href="https://www.tga.gov.au/news/safety-alerts/first-generation-antihistamines-winter-warning">1940s</a>) and newer, less-sedating (introduced in the 1980s) antihistamines.</p> <p>Less-sedating antihistamines used to treat allergic rhinitis include bilastine (Allertine), cetirizine (Zyrtec), loratadine (Claratyne) and fexofenadine (Telfast). Bilastine, which came onto the Australian market only last year, is only available from a pharmacy, on recommendation from a pharmacist. The others have been around longer and are available at supermarkets and in larger quantities from pharmacies. Cetirizine is the <a href="https://www.tga.gov.au/resources/publication/scheduling-decisions-interim/scheduling-delegates-interim-decisions-and-invitation-further-comment-accsacms-november-2016/35-cetirizine-hydrochloride#:%7E:text=Risks%20of%20cetirizine%20hydrochloride%20use,significant%20at%20the%20proposed%20doses.">most likely</a> (of the less-sedating antihistamines) to cause sedation.</p> <p>The older sedating antihistamines (such as promethazine) cross the blood-brain barrier, causing drowsiness and even brain fog the next day. They have lots of side effects and potential drug interactions, and as such have little place in the management of hay fever.</p> <p>The newer less-sedating antihistamines are <a href="https://australianprescriber.tg.org.au/articles/antihistamines-and-allergy.html#:%7E:text=Less%20sedating%20antihistamines%20are%20equally,an%20ongoing%20good%20safety%20profile">equally effective</a> as the older sedating ones.</p> <p>Antihistamines are usually taken orally (as a tablet or solution) but there are also topical preparations such as nasal sprays (azelastine) and eye drops. Antihistamine nasal sprays have <a href="https://www.sciencedirect.com/science/article/abs/pii/S108112061000743X">equal to or better efficacy</a> than oral antihistamines.</p> <p>The individual response to antihistamines varies widely. For this reason, you may need to trial several different types of antihistamines to see which one works best for you.</p> <p>Increasing the dose of an antihistamine, or combining an oral and topical antihistamine, does not provide any additional benefit. Paying extra for a brand name doesn’t offer any more or less effect than the generic (both have the same active ingredient and are <a href="https://www.tga.gov.au/news/news/generic-prescription-medicines-fact-sheet">bioequivalent</a>, which means they have the same outcomes for patients).</p> <h2>Steroid nasal sprays</h2> <p>If your symptoms don’t improve from antihistamines alone, a nasal spray containing a corticosteroid is often recommended.</p> <p>Corticosteroids prevent the release of several key chemicals that cause inflammation. How they work is complex: in part, corticosteroids “turn off” the production of late phase inflammatory mediators (cytokines and chemokines). This reduces the future release of more inflammatory mediators, which reduces inflammation.</p> <p>Corticosteroids and antihistamines have different mechanisms of action. Research shows corticosteroid nasal sprays are <a href="https://journals.sagepub.com/doi/full/10.2500/ajra.2016.30.4397">more effective</a> than antihistamines in controlling an itchy, runny, congested nose. But when instilled into the nose, corticosteroids <a href="https://aao-hnsfjournals.onlinelibrary.wiley.com/doi/10.1016/j.otohns.2007.10.027">also reduce</a> the eye symptoms of hay fever.</p> <p>There are also nasal sprays that contain both an antihistamine and corticosteroid.</p> <p>While there are a range of corticosteroid nasal sprays containing different active ingredients, a large study published this year shows they are all <a href="https://www.frontiersin.org/articles/10.3389/fphar.2023.1184552/full">about as effective as each other</a>, and work best when they have been taken for several days.</p> <h2>Sodium cromoglycate</h2> <p>Another medicine used to treat hay fever symptoms is sodium cromoglycate, which is available as an eye drop and over-the-counter in pharmacies.</p> <p>This medicine is known as a mast cell stabiliser. As the name suggests, it stabilises or prevents mast cells from breaking down. When mast cells break down, they release histamine and other chemicals that cause inflammation.</p> <p>This eye drop is both a preventative and treatment medicine, usually used before allergies strike. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9375451/">Evidence shows</a> it is effective at reducing the symptoms of allergic conjunctivitis (eye inflammation from allergies).</p> <h2>Decongestants</h2> <p>Decongestants constrict blood vessels. They can be taken orally, administered as a nasal spray, or instilled into the eyes. When administered into the eyes it will reduce redness, and when administered into the nose, it will stop it from running.</p> <p>However, decongestants should be used for a short duration only and are not for long term use. In fact, if a nasal spray decongestant is used for more than five days, you can experience something called “rebound congestion”: a severe stuffy nose.</p> <h2>Saline</h2> <p>Saline (saltwater) nasal sprays or irrigation products are also available to flush out the allergens and provide hay fever relief. While there are not many studies in the area, there is evidence that saline irrigation <a href="https://www.cochrane.org/CD012597/ENT_nasal-saline-allergic-rhinitis#:%7E:text=Saline%20irrigation%20may%20reduce%20patient,any%20outcomes%20beyond%20three%20months">may reduce hay fever symptoms</a>.

How to stay awake after a terrible night’s sleep

<p><strong>How to stay awake </strong></p> <p>There are ideals and then there’s real life. In truth, you will at times find yourself tired but still obligated to stay alert. Here’s how to stay awake and make those moments as painless as possible.</p> <p><strong>Play music</strong></p> <p>This brain hack works best if you opt for something cheery, with a beat that’s strong and fast but not exhausting (100 to 130 beats per minute). Music with heart-rate lowering tempos – think 60 beats per minute or less – can actually induce sleep, so consider yourself warned.</p> <p><strong>Go outside or place yourself near a bright light</strong></p> <p>Your body takes its sleep-wake cues from light, so draw back the curtains and let in the sunshine. If it’s not a sunny day, fool your system into thinking it is by cranking the dimmer switch up to maximum, and ensuring your workspace is properly illuminated with task lighting.</p> <p><strong>Drink water</strong></p> <p>Dehydration increases sleepiness. According to Harvard Health, keeping yourself hydrated can help to curb fatigue. It doesn’t necessarily have to be water, either – there are plenty of hydrating drinks that can count towards your daily fluid intake, even caffeinated beverages!</p> <p><strong>Exercise</strong></p> <p>Aerobic activity pumps oxygen through your system and releases hormones that give you energy. There are plenty of other health benefits from increasing your physical activity level, of course.</p> <p><strong>Stimulate your mind </strong></p> <p>Boredom itself promotes fatigue. Break the cycle by starting a conversation, engaging in a new activity, or reading an article about a topic that interests you.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.co.nz/healthsmart/how-to-stay-awake-after-a-terrible-nights-sleep" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

What to eat before bed if you want a good night’s sleep

<p><strong>What to eat before bed</strong></p> <p>It’s after 8 pm and you can feel your stomach grumbling. Should you stick it out until morning or head to the kitchen? Night-time eating tends to get a bad reputation – people often worry it causes weight gain, heartburn, indigestion or all three. But it all depends on what you reach for, says nutritionist Nishta Saxena.</p> <p>Saxena says there isn’t a clear-cut time of day that we have to stop eating. Studies have found that it’s not when you’re eating, but how much and what you’re eating which matters. Super salty snacks at the end of the day can, for example, make you dehydrated and interrupt your sleep – and they’re not the only culprits that can affect whether you have a good night’s rest.</p> <p>In general, it’s best to eat small portions before bed. Also try to stay away from foods high in protein or fat, which can be harder for our bodies to digest and can interrupt the natural cadence of our systems, which slow down for the night by producing sleep-inducing hormones like melatonin. Excessive sugar can also act like a stimulant – a bad choice if you’re trying to catch some Zzzs.</p> <p>Saxena suggests eating something that’s high in carbohydrates, which can promote sleep and help you to relax. This is because carbs don’t require as much blood flow or work from your body to digest and are therefore unlikely to interrupt your sleep. If you find yourself with an after-dinner case of the munchies, follow these tips on what to eat before bed.</p> <p><strong>Kiwis</strong></p> <p>Kiwis can help to promote sleep because they are rich in serotonin and antioxidants (such as Vitamins C and E). Serotonin helps to make you feel relaxed and certain antioxidants have sleep-promoting qualities. </p> <p>Plus, these fuzzy fruits are extremely high in vitamin C and our bodies can digest them quickly, says Saxena. They also support heart and digestive health as well as natural immunity.</p> <p><strong>Tart cherries</strong></p> <p>Tart cherries and tart cherry juice contain concentrated amounts of melatonin, a hormone that helps your body regulate sleep-wake cycles, says Saxena. Studies show that they can help to reduce insomnia, plus they also contain other sleep-inducing agents like tryptophan (a precursor of serotonin). </p> <p>Since tart cherries can be a little bit harder to find than other fruits, Saxena suggests keeping some in your freezer and using them to make a smoothie.</p> <p><strong>Nuts</strong></p> <p>Nuts are great for a variety of health benefits, says Saxena, and they’re also a good late-night snack. Just don’t dish out a whole cup of nuts, she warns, because they do contain surprising amounts of protein and fat. </p> <p>In particular, she recommends walnuts and almonds – they contain natural melatonin as well as magnesium, which has the potential to reduce insomnia in adults.</p> <p><strong>Popcorn</strong></p> <p>While pre-packaged microwave popcorn most likely contains too much salt to be a good bedtime snack, popping your own can satisfy people who are craving snack foods like chips. </p> <p>Popcorn is also relatively filling – just don’t drown your bowl in butter and salt.</p> <p><strong>Yoghurt</strong></p> <p>Dairy products, while not consumed by everyone, have a lot of components that stimulate sleep, says Saxena. Something like yoghurt doesn’t require a lot of digestive processes, and even full fat yoghurt doesn’t have a ton of fat in it, making it easy to digest. </p> <p>Plus, it’s filled with amino acids, like tryptophan, which promote sleep.</p> <p><strong>Green bananas</strong></p> <p>Saxena says a greenish banana, “almost the colour of a tulip stem,” is a great evening snack. At this point, the banana is full of starch, which means it hasn’t yet become sugar, and this can be great for our gut bacteria and also helps to promote sleep. </p> <p>She adds that the banana should be firm and have a tiny bit of yellow in the midsection. If it has black spots, it’s too ripe to help with sleep and won’t provide a benefit.</p> <p><strong>Warm milk</strong></p> <p>The benefits of warm milk for sleep are well-documented, says Saxena. This is in part because milk contains tryptophan, an amino acid that promotes sleep. Warm fluids in general can relax our digestive muscles. </p> <p>“It can be a self-care moment when you’re having something warm,” Saxena says. “Your hands are wrapped around the mug and it’s a sensory experience.”</p> <p><strong>Cottage cheese</strong></p> <p>While cottage cheese has lots of protein, it also has the benefits of dairy, including amino acids, that help to promote sleep. It’s also nutrient-dense, containing calcium, magnesium, iron, and phosphorus, which are essential for bodily function. </p> <p>It can also be a good late-night snack for athletes, because it’s high in the protein casein, which helps to reduce muscle breakdown overnight. Still, stay away from other cheeses before bed – most are very high in fat and easy to overeat, warns Saxena.</p> <p><strong>Oatmeal</strong> </p> <p>While people often think of oatmeal as a breakfast food, oats are high in melatonin and so can make a good bedtime snack. Like dairy products, oats also contain the amino acid tryptophan. </p> <p>You can also spice up your oatmeal with many of the other foods that are okay to eat before bed – tart cherries, yogurt, or almond butter, for example.</p> <p><strong>Pasta</strong></p> <p>If you’re really hungry, try some pasta – but keep the portion small and be careful to not load your dish with toppings that are high in protein or fat. </p> <p>For example, you don’t want to have a super-cheesy meatball pasta before bed, says Saxena. But a small serving of plain pasta with pesto sauce might do the trick.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.com.au/healthsmart/conditions/sleep/what-to-eat-before-bed-if-you-want-a-good-nights-sleep?pages=1" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

"A night in hospital and a trip to the burns unit later”: Concerned mum's warning against popular fruit

<p><em><strong>Warning: This article contains images that some readers may find distressing.</strong></em></p> <p>An Aussie mum has taken to the internet and shared photos of her son’s severe burns that came as a result of him playing with a popular fruit. “A night in hospital and a trip to the burns unit later.” She began in her Facebook post.</p> <p>Her son Otis was playing happily outside with a lime in the sunshine, but the next day horror ensued.</p> <p>“It wasn’t until the next day that we noticed a rash appeared.” The mother said.</p> <p>The parents had assumed the rash must’ve been an allergic reaction to the lime juice, however, the rash quickly developed into a “horrific burn,” she added.</p> <p>The parents took Otis to the hospital where they were informed their son was suffering from a condition called phytophotodermatitis.</p> <blockquote class="instagram-media" style="background: #FFF;

Hot flushes, night sweats, brain fog? Here’s what we know about phytoestrogens for menopausal symptoms

<p><a href="https://theconversation.com/profiles/caroline-gurvich-473295">Caroline Gurvich</a>, <em><a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a></em>; <a href="https://theconversation.com/profiles/jane-varney-963066">Jane Varney</a>, <em><a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a></em>, and <a href="https://theconversation.com/profiles/jayashri-kulkarni-185">Jayashri Kulkarni</a>, <em><a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a></em></p> <p>While some women glide through menopause, <a href="https://pubmed.ncbi.nlm.nih.gov/26271251/">more than 85%</a> experience one or more unpleasant symptoms, which can impact their physical and mental health, daily activities and quality of life.</p> <p>Hot flushes and night sweats are the most common of these, affecting <a href="https://pubmed.ncbi.nlm.nih.gov/29393299/">75% of women</a> and the symptom for which most women seek treatment. Others include changes in weight and body composition, skin changes, poor sleep, headaches, joint pain, vaginal dryness, depression and brain fog.</p> <p>While menopause hormone therapy is the most effective treatment for menopausal symptoms, it is sometimes not recommended (such as following breast cancer, as there is conflicting evidence about the safety of menopause hormone therapy following breast cancer) or avoided by people, who may seek non-hormonal therapies to manage symptoms. In Australia it is estimated <a href="https://pubmed.ncbi.nlm.nih.gov/26224187/">more than one-third</a> of women seek complementary or alternative medicines to manage menopausal symptoms.</p> <p>But do they work? Or are they a waste of time and considerable amounts of money?</p> <h2>What’s on the market?</h2> <p>The <a href="https://pubmed.ncbi.nlm.nih.gov/30868921/">complementary or alternative interventions</a> for menopausal symptoms are almost as varied as the symptoms themselves. They include everything from mind-body practices (hypnosis, cognitive behavioural therapy and meditation) to alternative medicine approaches (traditional Chinese medicine and acupuncture) and natural products (herbal and dietary supplements).</p> <p>There is some evidence to support the use of <a href="https://pubmed.ncbi.nlm.nih.gov/23435026/">hypnosis</a> and <a href="https://pubmed.ncbi.nlm.nih.gov/22336748/">cognitive behaviour therapy</a> for the treatment of hot flushes. Indeed these therapies are recommended in <a href="https://www1.racgp.org.au/getattachment/bfaa5918-ddc4-4bcb-93cc-d3d956c1bbfd/Making-choices-at-menopause.aspx">clinical treatment guidelines</a>. But there is less certainty around the benefit of other commonly used complementary and alternative medicines, particularly nutritional supplements.</p> <p>The most popular <a href="https://pubmed.ncbi.nlm.nih.gov/26224187/">nutritional supplements</a> for hot flushes are phytoestrogens (or plant estrogens). This trend has been driven in part by <a href="https://www.dailymail.co.uk/femail/article-11915645/HRT-not-supplement-created-experts-women-RAVING-effects.html">supplement companies</a> that promote such agents as a safer or more natural alternative to hormone therapy.</p> <h2>What are phytoestrogens?</h2> <p>Phytoestrogens are plant-derived substances that can show oestrogen-like activity when ingested.</p> <p>There are numerous types including isoflavones, coumestans and lignans. These can be consumed in the form of food (from whole soybeans, soy-based foods such as tofu and soy milk, legumes, wholegrains, flaxseeds, fruits and vegetables) and in commercially produced supplements. In the latter category, extracts from soy and red clover yield isoflavones and flaxseed gives us lignans.</p> <p>Because declining oestrogen levels drive menopausal symptoms, the theory is that consuming a “natural”, plant-based substance that acts like oestrogen will provide relief.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/528788/original/file-20230529-17-mh3zlk.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/528788/original/file-20230529-17-mh3zlk.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/528788/original/file-20230529-17-mh3zlk.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=400&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/528788/original/file-20230529-17-mh3zlk.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=400&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/528788/original/file-20230529-17-mh3zlk.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=400&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/528788/original/file-20230529-17-mh3zlk.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=503&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/528788/original/file-20230529-17-mh3zlk.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=503&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/528788/original/file-20230529-17-mh3zlk.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=503&amp;fit=crop&amp;dpr=3 2262w" alt="Soy-rich foods on a table: edamame, soy milk, soy sauce" /></a><figcaption><span class="caption">Phytoestrogens can be consumed in foods like tofu or soy milk.</span> <span class="attribution"><a class="source" href="https://www.shutterstock.com/image-photo/soy-bean-tofu-other-products-187030769">Shutterstock</a></span></figcaption></figure> <h2>What does the evidence say?</h2> <p>In the case of isoflavones, initial support came from <a href="https://pubmed.ncbi.nlm.nih.gov/23562010/">epidemiological data</a> showing <a href="https://pubmed.ncbi.nlm.nih.gov/15919681/">women in Asian countries</a>, consuming a traditional, phytoestrogen-rich diet (that is, one including tofu, miso and fermented or boiled soybeans), experienced fewer menopausal symptoms than women in Western countries.</p> <p>However, several factors may influence the effect of dietary phytoestrogens on menopausal symptoms. This includes gut microbiota, with research showing only around <a href="https://pubmed.ncbi.nlm.nih.gov/15919681/">30% of women</a> from Western populations possess the gut microbiota needed to convert isoflavones to their active form, known as equol, compared to an estimated 50–60% of menopausal women from Japanese populations.</p> <p>Circulating oestrogen levels (which drop considerably during menopause) and the <a href="https://academic.oup.com/humupd/article/11/5/495/605995">duration of soy intake</a> (longer-term intake being more favourable) may also influence the effect of dietary phytoestrogens on menopausal symptoms.</p> <p>Overall, evidence regarding the benefit of phytoestrogens for hot flushes is fairly mixed. A <a href="https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD001395.pub4/full">Cochrane review</a> synthesised study results and failed to find conclusive evidence phytoestrogens, in food or supplement form, reduced the frequency or severity of hot flushes or night sweats in perimenopausal or postmenopausal women.</p> <p>The review did note genistein extracts (an isoflavone found in soy and fava beans) may reduce the number of hot flushes experienced by symptomatic, postmenopausal women, though to a lesser extent than hormone therapy.</p> <p>Another <a href="https://pubmed.ncbi.nlm.nih.gov/36253903/">recent study</a> showed marked reductions in hot flushes in women following a low fat, vegan diet supplemented with daily soybeans. However, it was questioned whether concurrent weight loss contributed to this benefit.</p> <p>In Australia, <a href="https://ranzcog.edu.au/wp-content/uploads/2022/05/Managing-menopausal-symptoms.pdf">clinical guidelines</a> do not endorse the routine use of phytoestrogens. <a href="https://www.nice.org.uk/guidance/ng23/chapter/Recommendations#managing-short-term-menopausal-symptoms">Guidelines for the United Kingdom</a> note some support for the benefit of isoflavones, but highlight multiple preparations are available, their safety is uncertain and interactions with other medicines have been reported.</p> <h2>Can phytoestrogens help the psychological symptoms of menopause?</h2> <p>Less research has explored whether phytoestrogens improve psychological symptoms of menopause, such as depression, anxiety and <a href="https://theconversation.com/brain-fog-during-menopause-is-real-it-can-disrupt-womens-work-and-spark-dementia-fears-173150">brain fog</a>.</p> <p>A recent systematic review and <a href="https://pubmed.ncbi.nlm.nih.gov/33987926/">meta-analysis</a> found phytoestrogens reduce depression in post- but not perimenopausal women. Whereas a more <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9022873/">recent clinical trial</a> failed to find an improvement.</p> <p>Some research suggests phytoestrogens may reduce the <a href="https://www.sciencedirect.com/science/article/pii/S0960076015301254?via=ihub">risk of dementia</a>, but there are no conclusive findings regarding their effect on menopausal brain fog.</p> <h2>The bottom line</h2> <p>At present there is uncertainty about the benefit of phytoestrogens for menopause symptoms.</p> <p>If you do wish to see if they might work for you, start by including more phytoestrogen-rich foods in your diet. Examples include tempeh, soybeans, tofu, miso, soy milk (from whole soybeans), oats, barley, quinoa, flaxseeds, sesame seeds, sunflower seeds, almonds, chickpeas, lentils, red kidney beans and alfalfa.</p> <p>Try including one to two serves per day for around three months and monitor symptoms. These are nutritious and good for overall health, irrespective of the effects on menopausal symptoms.</p> <p>Before you trial any supplements, discuss them first with your doctor (especially if you have a history of breast cancer), monitor your symptoms for around three months, and if there’s no improvement, stop taking them.<!-- Below is The Conversation's page counter tag.

John Travolta’s iconic suit snatches a sweaty sum at auction

<p>John Travolta’s sweat stains have hit the market, snagging a staggering sum, alongside the iconic <em>Saturday Night Fever</em> white three-piece suit.</p> <p>The look rose to international fame when Travolta - as Tony Manero - took to the dancefloor in the 1977 classic, joining Stephanie Mangano for an intense disco dance competition. </p> <p>But it was the film’s promotional imagery that truly immortalised the suit - despite popular, yet incorrect, belief that Travolta had flaunted it during his solo ‘Night Fever’ dance. In posters - as well as on VCR, DVD, and CD covers - Travolta can be seen with his right arm in the air, on a dancefloor, white polyester front and centre. </p> <p>As Costume designer Patrizia von Brandenstein explained to the <em>New York Post</em>, they were looking for “a white, three-piece suit: dressy, inexpensive and polyester. There was a producer who thought a black suit would be more elegant. But heroes wear white; it’s as simple as that. </p> <p>“The pastel suits were nice and pretty, but John’s character is very much a hero. Plus, it needed to be something that a boy who works in a paint store would be able to afford. I think the suit sold for $150 or $200.”</p> <p>Initially purchased off the rack in Brooklyn for $100, the jacket - with matching waistcoat, flared trousers, black shirt, and Travolta’s 45-year-old sweat stains - was expected to fetch up to $250,000 USD (~$374,000 AUD) when it went under the hammer at Los Angeles’ Julien’s Auctions.</p> <p>Despite its distinct lack of a thorough cleaning, the suit did find a new home, with a buyer dishing out a total of approximately $388,692 AUD to call it their own.</p> <p>As a spokesperson for the auction house explained, “This suit is considered to be one of the most iconic costumes in cinema history. It is one of only two known to exist that was used during production. It has never been exhibited or sold at auction before.</p> <p>“It has become emblematic of not only the film but of the whole disco era.”</p> <p>The suit in question was actually one of a few purchased by the film’s costume designer - two were used on set, rotated in and out while the other dried, and another was used for promotional material - and was given to Julien’s Auctions by an anonymous collector who had received it from <em>Saturday Night Fever</em>’s director, John Badham in 1991. </p> <p>As for why the iconic outfit was being sold in its unique condition, the executive director of Julien’s Auctions had a simple explanation. </p> <p>“The sweat is how you know it’s authentic,” Martin J Nolan told <em>The Guardian</em>.</p> <p>“It was incredibly hot during filming, so you can still see the sweat marks around his waist. We never wash memorabilia. People want the stains, the DNA, particularly when a suit like this one hasn’t been auctioned before.”</p> <p><em>Images: Getty</em></p>

Sleepless nights can affect your memory

<p>One-third of a life span is a massive slice of time to spend with our eyes closed, but there's a very good reason humans need so much sleep.</p> <p>We just don't know what it is.</p> <p>What does sleep do to our brains? Like a sleep-deprived student trying to muddle through a morning exam, scientists trying to unravel this enduring mystery have been labouring in a heavy fog.</p> <p>But a new study could help answer this fundamental question, suggesting those hours of slumber allow the brain to rewire the crucial connections between the brain's neurons that clog up when we're awake.</p> <p>This nightly reset is vital for building and preserving memory, as well as our ability to learn new skills and engage with our waking realities, according to the German researchers.</p> <p>But just one sleepless night may be all it takes to stop the brain's ability to recalibrate its connections, overloading its synaptic activity and ultimately hampering its ability to form and retain new memories, according to the research paper published on Wednesday in <strong><em><span style="text-decoration: underline;"><a href="http://nature.com/articles/doi:10.1038/ncomms12455" target="_blank" rel="noopener">Nature Communications</a></span></em></strong>.</p> <p>The researchers set out to test the "synaptic homeostasis hypothesis" that a good night's sleep allows the brain's neuron signals to cut through the chaotic "noise" and improve its capacity to encode, or remember, new information.</p> <p>It is virtually impossible directly test this theory in humans.</p> <p>Using non-invasive transcranial magnetic stimulation (TMS), the research team was able to indirectly compare the synaptic activity in the brains of 20 individuals (aged between 19 and 25) after one night's sleep or after one night of sleep deprivation.</p> <p>The research team used small magnetic pulses to zap the motor cortex - the region responsible for movement - to trigger a muscle twitch in participant's left hands.</p> <p>After their sleepless night, participants needed a much lower pulse to activate the hand muscles compared their well-rested counterparts, suggesting their sleep-deprived brains were more excitable, said the researchers lead by psychiatrists Dr Christoph Nissen at Freiburg University, Germany.</p> <p>The researchers then used the magnetic pulses to imitate the brain activity used to encode new memories. The sleep-deprived participants showed a weaker synaptic response and performed worse in a word-pair memory exercise.</p> <p>Their blood samples also showed reduced BDNF, a molecule that regulates synaptic plasticity needed for memory and learning.</p> <p>"Our study provides the first evidence for sleep-wake-dependent dissociation of associative and homeostatic synaptic plasticity in humans," the researchers concluded.</p> <p>The results may pave the way for effective treatments for neuropsychiatric disorders.</p> <p>There is some evidence the experimental treatment - therapeutic sleep deprivation - can improve mood among people with major depression.</p> <p>The findings suggest the therapy shifts the brain of a depressed patient "into a more favourable window of associative plasticity", the authors suggested.</p> <p>Overall, "the findings were a significant step towards a better understanding of basic mechanisms for health performance and potential alterations in neuropsychiatric disorders," they concluded.</p> <p>What’s the minimum amount of sleep you can survive on before your cognitive performance is affected?

Here’s how you can bag a night at Bag End

<p dir="ltr">While many visitors to New Zealand’s Hobbit movie set have gone there and back again, no-one has had the chance to stay overnight - until now that is.</p> <p dir="ltr">In celebration of the 10th anniversary of <em>The Hobbit: An Unexpected Journey</em>, Airbnb will be offering a few lucky fans the opportunity to spend the night at the original movie set.</p> <p dir="ltr">Winners will score one of three overnight stays at the set in Waikato, with access to the Hobbit Holes, Millhouse and The Green Dragon Inn, a private tour of the movie set, and an evening banquet in the Green Dragon - think beef and ale stew, fresh bread, chickens and ale.</p> <p dir="ltr">Two decades after the working farm caught the attention of <em>Lord of the Rings</em> director Peter Jackson, the farm’s owner Russell Alexander said he was excited to offer guests the experience of living like a Hobbit.</p> <p dir="ltr">“We’ve welcomed millions of passionate fans to the Hobbiton Movie Set, but never before has anyone had the opportunity to spend a night in Middle-earth,”he said. </p> <p dir="ltr">“I am delighted to share the beauty of my family’s farm and pleased to be hosting this iconic location on Airbnb for fans from around the world.”</p> <p dir="ltr">The three two-night stays will come with a four-guest limit and cost $10 a night to mark the 10th anniversary.</p> <p dir="ltr">Each of the stays will take place on March 2-4, 9-11 and 16-18.</p> <p dir="ltr">Unsurprisingly, there are some rules for the lucky guests who stay on-set, with plenty of references to the <em>Hobbit </em>and <em>Lord of the Rings</em> sagas, including “no unexpected parties”, “magical rings permitted, but keep them secret, keep them safe”, “straying far at night is discouraged, thanks to multiple troll sightings of late”, and “pony parking” available only at the Green Dragon Inn.</p> <p dir="ltr">To go in the running, applicants can request to book one of the stays from Wednesday December 14.</p> <p dir="ltr">Applicants must have a history of positive reviews on Airbnb, have an Airbnb profile and be over the age of 18.</p> <p dir="ltr">To enter, head <a href="https://news.airbnb.com/hobbiton/" target="_blank" rel="noopener">here</a>.</p> <p><span id="docs-internal-guid-60557783-7fff-febe-b850-1e33b85026da"></span></p> <p dir="ltr"><em>Images: Airbnb</em></p>

What position should I sleep in, and is there a ‘right’ way to sleep?

<p>After 50 years of research, eminent Stanford University sleep researcher William Dement reportedly <a href="https://www.physoc.org/magazine-articles/book-review-why-we-sleep-by-matthew-walker/" target="_blank" rel="noopener">said</a> the only solid explanation he knows for why we sleep is “because we get sleepy”.</p> <p>Even though sleep may be, as one researcher <a href="https://www.nationalgeographic.com/science/article/to-discover-the-point-of-sleep-scientists-breed-flies-that-nod-off-on-demand" target="_blank" rel="noopener">put</a> it, “the only major behaviour in search of a function”, it clearly does <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4434546" target="_blank" rel="noopener">matter</a> for our health and wellbeing.</p> <p>But are we doing it right? What does the research say about sleeping position?</p> <h2>Is there a correct position to sleep in?</h2> <p>Most people <a href="https://nsuworks.nova.edu/ijahsp/vol2/iss1/7/" target="_blank" rel="noopener">prefer</a> to sleep on their <a href="https://doi.org/10.2147/NSS.S145777" target="_blank" rel="noopener">side</a>. This is good to hear, as those who lie on their backs are more likely to be <a href="https://doi.org/10.1093/sleep/6.1.52" target="_blank" rel="noopener">poor sleepers</a> or have <a href="https://doi.org/10.1378/chest.118.4.1018" target="_blank" rel="noopener">breathing difficulties</a> during the night.</p> <p>In most cases, we tend to move around quite a lot during the night. <a href="https://doi.org/10.2147/NSS.S145777" target="_blank" rel="noopener">One study</a> of 664 sleepers found, on average, that participants spent about 54% of their time in bed sleeping on their side, about 37% on their back, and about 7% on their front.</p> <p>Males (especially those aged under 35) tend to be most restless, with <a href="https://doi.org/10.2147/NSS.S145777" target="_blank" rel="noopener">more</a> position shifts, and arm, thigh, and upper-back movements during the night.</p> <p>This may not be a bad thing, as allowing your body to move during the night is generally a good idea.</p> <p>During sleep, your body will keep track of any pain or discomfort and adjust position accordingly. This is why we usually avoid developing <a href="https://journals.sagepub.com/doi/10.1177/15347346221081603" target="_blank" rel="noopener">bedsores</a> (or pressure ulcers) in everyday life.</p> <p>If you find you can’t move because your partner (or dog) is taking up too much room in the bed, consider switching sides or getting a larger bed.</p> <p>And don’t tuck yourself in too tightly; give yourself some room to move around on either side.</p> <p>Being comfortable is key. There is <a href="https://www.oarsijournal.com/article/S1063-4584(19)30543-6/fulltext" target="_blank" rel="noopener">no quality research</a> providing clear evidence for an “optimal sleep position”. Your age, weight, environment, activities and whether you’re pregnant, all <a href="https://academic.oup.com/sleep/article/15/2/143/2742862" target="_blank" rel="noopener">play a role</a> in which sleep position is best for your body.</p> <p>Ideally, we can find a position that helps us get a good night’s sleep, and one that avoids us waking up in any pain.</p> <p>Even with our chosen position, some layouts are better than others. In one <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0260582" target="_blank" rel="noopener">study</a>, people who rested in a position where there is a rotation of the spine (such as the unsupported side position), woke up with more pain in the morning.</p> <p>Nonetheless, although some forms of side-sleeping may cause a bit of load on the spine, it appears the side positions, in general, are still better than the <a href="https://nsuworks.nova.edu/ijahsp/vol5/iss1/6/" target="_blank" rel="noopener">other options</a>.</p> <h2>What pillow should I choose?</h2> <p>Choosing the right pillow is vital for a good night’s sleep.</p> <p>A lack of support for the head and neck during sleep has been found to severely impact <a href="https://theconversation.com/whats-a-t7-vertebra-and-what-happens-when-you-injure-it-2-experts-explain-156947" target="_blank" rel="noopener">spine</a> alignment, and cause <a href="https://www.clinbiomech.com/article/S0268-0033(21)00083-8/fulltext" target="_blank" rel="noopener">muscle problems</a> such as neck pain, shoulder pain and <a href="https://www.youtube.com/watch?v=ZqwGTso2Wmc" target="_blank" rel="noopener">muscle stiffness</a>.</p> <p>Promisingly, the pillow <a href="https://doi.org/10.1016/j.clinbiomech.2021.105353" target="_blank" rel="noopener">material</a> does not appear to affect the spine. Instead, the shape and the height is what matters. A U-shaped pillow may help you have a <a href="https://www.sciencedirect.com/science/article/abs/pii/S0003687015300338" target="_blank" rel="noopener">longer night’s sleep</a>, and a roll-shaped pillow can reduce morning pain and bedtime pain in those suffering from <a href="https://pubmed.ncbi.nlm.nih.gov/9502063/" target="_blank" rel="noopener">chronic pain</a>.</p> <p>Unfortunately, science has not given us an answer on what is the <a href="https://www.oarsijournal.com/article/S1063-4584(19)30543-6/fulltext" target="_blank" rel="noopener">optimal mattress</a>. With everyone sleeping differently, this would be hard to compare over the long term.</p> <p>However, there are bad mattresses. If your bed is sagging, has lost its firmness, develops noisy springs, or shows clear signs of wear and tear, consider changing your mattress.</p> <p>Rotating the mattress can help with its longevity and improve comfort. This should be done <a href="https://www.sleepfoundation.org/mattress-information/should-you-flip-or-rotate-your-mattress" target="_blank" rel="noopener">at least</a> one to two times per year.</p> <h2>Other tips for a restful night’s sleep</h2> <p>Set a cooler room temperature. The ideal temperature for sleep is <a href="https://www.sleepfoundation.org/bedroom-environment/best-temperature-for-sleep" target="_blank" rel="noopener">18.3℃</a> (ranging between 15-19℃); <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5446217/" target="_blank" rel="noopener">higher temperatures</a> can affect sleep.</p> <p>Allow some airflow in the room. Besides bringing nice, fresh air, it also clears away any accumulated heat, keeping us nice and <a href="https://link.springer.com/article/10.1007/s00484-007-0120-9" target="_blank" rel="noopener">cool</a> during the night.</p> <p>Some medications, such as certain types of <a href="https://www.frontiersin.org/articles/10.3389/fphys.2022.841181/full" target="_blank" rel="noopener">antihistamines</a>, may make it easier to get to sleep. On the other hand, stimulants such as caffeine can drastically affect the <a href="https://pubmed.ncbi.nlm.nih.gov/27527212/" target="_blank" rel="noopener">quality</a> of your sleep.</p> <p>Finally, be sure not to go to bed with a full bladder, as having to get up at night to <a href="https://onlinelibrary.wiley.com/doi/epdf/10.1002/nau.24839" target="_blank" rel="noopener">wee</a> can impact sleep.</p> <p><strong>This article originally appeared on <a href="https://theconversation.com/what-position-should-i-sleep-in-and-is-there-a-right-way-to-sleep-189873" target="_blank" rel="noopener">The Conversation</a>. </strong></p> <p><em>Image: Shutterstock</em></p>
