Common myths around sleep like snoring is harmless or having a drink helps fall asleep not only shape poor habits but may also pose a significant public health threat, say researchers.

The claim by some people that they can get by on five hours of sleep was among the top myths researchers were able to dispel based on scientific evidence.

This myth also poses the most serious risk to health from long-term sleep deficits, said the study published online in Sleep Health journal on Tuesday.

“Sleep is a vital part of life that affects our productivity, mood, and general health and well-being,” said study lead investigator Rebecca Robbins at New York University Langone Health.

“Dispelling myths about sleep promotes healthier sleep habits which, in turn, promote overall better health,” she added.

To reach this conclusion, researchers reviewed more than 8,000 websites to identify the 20 most common assumptions about sleep.

With a team of sleep medicine experts, they ranked them based on whether each could be dispelled as a myth or supported by scientific evidence, and on the harm that the myth could cause.

Another common myth relates to snoring.

While snoring can be harmless, it can also be a sign of sleep apnea, a potentially serious sleep disorder.

The authors encourage patients not to dismiss loud snoring, but rather to see a doctor since this sleep behaviour may lead to heart stoppages or other illnesses.

The study authors also found sufficient evidence that, despite beliefs to the contrary, drinking alcoholic beverages before bed is indeed unhealthy for sleep.

“Sleep is important to health, and there needs to be greater effort to inform the public regarding this important public health issue,” noted study senior investigator Girardin Jean Louis.

Robbins and her colleagues suggest creating a consistent sleep schedule and spending more time, at least seven hours, asleep. (IANS)

Lack of Sleep Alters Fat Metabolism, Says Study

Nonetheless, according to Buxton, the study gives worthwhile insight into how we handle fat digestion

Lack of sleep can be harmful as it can make participants feel less full after eating and metabolise the fat in food differently, says a study, adding to the mounting evidence that how harmful lack of sleep can be.

The study, published in the journal of Lipid Research, by Pennsylvania State University found that sleep disruption has been known to be have harmful effects on metabolism for some time.

Orfeu Buxton, a professor at Penn State, added that long-term sleep restriction puts people at a higher risk of obesity and diabetes.

Kelly Ness, now a postdoctoral fellow at the University of Washington, ran the study when she was a graduate student in Buxton’s lab.

She and other researchers not only collected data but also spent time, “interacting with the subjects, playing games with them, talking with them — helping to keep them awake and engaged and positive.”

To find out how the uncomfortable schedule affected metabolism, the researchers gave participants a standardized high-fat dinner, a bowl of chili mac, after four nights of sleep restriction.

“It was very palatable — none of our subjects had trouble finishing it — but very calorically dense,” Ness said, adding that most participants felt less satisfied after eating the same rich meal while sleep deprived than, when they had eaten it well-rested.

Researchers then compared blood samples from the study participants. They found that sleep restriction affected the postprandial lipid response, leading to faster clearance of lipids from the blood after a meal. That could predispose people to put on weight.

“The lipids weren’t evaporating — they were being stored,” Buxton explained.

This study was highly controlled, which makes it an imperfect model for the real world, Ness said.

It focused on healthy young people, who are usually at a lower risk of cardiovascular disease, and all of the participants were men.

The researchers also wondered whether giving more recovery time would change the magnitude of recovery they observed.
