Top 8 sleep myths that can harm your health

Top 8 sleep myths that can harm your healthTop 8 sleep myths that can harm your healthHumans spend roughly one-third of their lives sleeping. Despite this, sleep still remains something of a mystery.However, we do know that sleep is deeply connected to our well-being, mood, and health.A night of bad sleep means more than just being grumpy in the morning. In the short term, it can mean poor performance at work or school. But chronic sleep deprivation can lead toserious health problemsincluding increasing a parties risk of heart attack and early mortality.Sleep scientists say that more needs to be done to educate the public about healthy sleep behaviors - and dispel rumors about unhealthy ones.Follow Ladders on FlipboardFollow Ladders magazines on Flipboard covering Happiness, Productivity, Job Satisfaction, Neuroscience, and moreA new study published in the journalSleep Healthis doing just that by taking on pervasive sleep myths and debunking them.In their study, researchers put toge ther an exhaustive list of misconceptions of sleep and narrowed them down to 20.The myths were ranked according to two different characteristics how false they were and their potential impact on public health.These are the top eight most harmful sleep myths from that list.Myth 1 Many adults need only five hours or less of sleep for general healthResearchers rated this myth as having the most potential harm on public health by far.Habitual sleep deprivation is associated with diverse andfar-reaching health effects and none of them are good.Sleep deprivation will affect your heart (increasing risk of hypertension and heart attack) and your mind (decreasing cognitive functioning and increasing risk of depression). Risk of diabetes and obesity also increase.For adults,the Centers for Disease Control and Prevention (CDC) recommendsbetween seven and nine hours of sleep per night, and there really isnt a shortcut to get around it.There may be variability in how much sleep an individual nee ds but I dont know that in an individual you can change that very much. I think you can get used to less sleep, but youre getting used to being miserable, saidDr. Steven H. Feinsilver, director of the Center for Sleep Medicine at Lenox Hill Hospital in New York City. Feinsilver was notlage affiliated with the research.Myth 2 Watching television is a good way to relax before bedYoure probably already aware that this one is a no-no. And it goes for more than just television. Cellphones, tablets, and all kinds of personal electronics are not a good idea when youre getting ready for bed.Researchers have increasingly focused onblue light emitted by screensand its effect on sleep and negative sleep-related health outcomes.Beds are for sleeping, with one exception. Watching television and the internet are not it, said Feinsilver.Myth 3 In terms of your health, it doesnt matter what time of day you sleepOur bodies tend to follow a natural rhythm of wakefulness and sleep that is attuned to s unrise and sunset for a reason.However, due to our careers, families, and social lives, we dont always do our sleeping during the night.While some missed sleep here and there isnt necessarily a big deal, shifting your sleep schedule long term isnt healthy.The study authors write that individuals who work night-shift jobs often experience circadian rhythm desynchronization and lower quality sleep. They also have a higher risk for health outcomes including depression and diabetes.Timing of sleep is important, said the studys author Rebecca Robbins, PhD, a postdoctoral fellow at NYU School of Medicine in the Center for Healthful Behavior Change, Thats why we see health risks cluster among individuals who work on shift schedules.Myth 4 Lying in bed with eyes closed is almost as good as sleepingYou may feel like youre getting sufficient rest lying in bed, even if you cant quite get to sleep, but researchers rated this myth as majorly false as well as potentially harmful.Everything from y our brain to your heart to your lungs function differently when sleeping compared to being awake. If you know youre awake, the rest of your body does too.One is either sleeping or awake with little overlap, write the authors. Available evidence is showing that cognitive activity when a person is sleeping is distinctly different from wake with eyes closed.Myth 5 Being able to fall asleep anytime and anywhere is a sign of a healthy sleep systemA healthy sleeper actually takes a couple of minutes to fall asleep. We do see that if people fall asleep right away that can be a sign that they are not getting quite enough sleep, said Robbins.Yes, it may seem like a gift, but falling asleep instantly, whether on an airplane or in a boring meeting, could actually mean that youre sleep deprived.Feinsilver even calls this myth dangerous, because it minimizes the idea of excessive daytime sleeping as being bad for you or being a sign of something thats bad for you.Myth 6 Alcohol before bed will i mprove your sleepA Pernod digestif after dinner. A nip of brandy before bed. Some of grandpas old cough medicine. Whatever your poison, it wont help you sleep any better. In fact, it will likely make you feel worse the next day.Not only is that tremendously wrong, but its also pretty dangerous. Its really terrible for sleep, said Feinsilver.He also notes that a nightcap can alsocause sleep apnea or make it worse.Myth 7 Your brain and body can learn to function just as well with less sleepBetween work, friends, and family, who has time for a full nights sleep?Its just this common belief that if you try a little bit harder, you might be able to survive the consequences of insufficient sleep. You just adapt a little bit more or you have another cup of coffee and youll be able to get by and power through. We hear that all the time, said Robbins.However, its just not true. As much as wed like to think we can train our bodies to need less sleep, the science says the opposite.All of the ev idence shows, without a shadow of a doubt, that chronic insufficient sleep, of five-six hours or less, is associated with a host of unfavorable consequences, she said.Myth 8 Although annoying for bed partners, loud snoring is mostly harmlessLoud snoring is actually one of the most common symptoms of sleep apnea, a disorder in which an individual can actually stop breathing while asleep.Chronic loud snoring can indicate that the airway is being blocked at night. But not all snoring is a sign of sleep apnea.Sleep apnea affects quality of sleep. Soif you snore loudly and you suffer from fatigueor sleepiness during the day, those symptoms together could mean you have it.Individuals with other health conditions including being overweight or obese, having high blood pressure, or being a smoker increase the risk of sleep apnea.The bottom lineIn a new publication, researchers say that common misconceptions about sleep can lead to unhealthy sleep behaviors. To fight back against behauptung s leep myths, they debunked 20 of the most common of these myths, including things like watching television before bed is a good way to relax, and adults need five hours or less sleep for general health.Sleep quality is associated with both positive and negative health outcomes. Researchers hope that by debunking these myths, individuals will gain a better understanding of sleep and improve their own sleep behaviors, thereby also improving their health.We believe that these myths are one reason that the population hasnt yet warmed to the idea of making sleep a priority, said Rebecca Robbins, PhD, a postdoctoral fellow at NYU School of Medicine in the Center for Healthful Behavior Change.If we dont do the intervention work or the public health campaign work to annihilate these myths or address them head on, debunk them, and help people realize and kind of motivate to put into practice the evidence-based behaviors, were limiting our potential for good sleep and ultimately good health, s he said.This article first appeared on Healthline.You might also enjoyNew neuroscience reveals 4 rituals that will make you happyStrangers know your social class in the first seven words you say, study finds10 lessons from Benjamin Franklins daily schedule that will double your productivityThe worst mistakes you can make in an interview, according to 12 CEOs10 habits of mentally strong people
