110 wrong things about sleep by Researchers of NY
Let’s talk about 10 wrong things about sleep. What they thought about the dream can be nothing more than an impossible dream.
Many of us have notions about sleep that, in fact, have little basis and can even be harmful to our health, according to researchers at the School of Medicine at Langone Health University of New York, who conducted a study published on Tuesday in the journal Sleep Health.
“There is a link between good sleep and our waking success,” said the study’s principal investigator, Rebecca Robbins, a postdoctoral researcher at the Department of Population Health at NYU Langone Health. “And yet, we often find ourselves discrediting myths, whether to the media, friends, relatives or a patient.”
Robbins and his colleagues reviewed 8,000 websites to discover what we thought we knew about healthy sleep habits and then presented those beliefs to a carefully selected team of sleep medicine experts. They determined which were myths and then classified them by the degree of falsehood and importance to health.
Here are 10 very wrong and unhealthy assumptions that we usually make about sleep, an act in which we spend approximately one third of our lives or, if we live to 100, about 12,227 combined days.
Stop yawning It’s time to put these erroneous dream myths to sleep.
1. Adults need five or less hours of sleep
“If you would like to have the ability to perform in the best possible way during the day, not be sick, be mentally strong, be able to have the lifestyle you would enjoy, how many hours do you have to sleep?” Asked the study’s principal investigator, Girardin Jean-Louis, professor in the Department of Population Health.
“It turns out that a lot of people felt that sleeping less than five hours a night was fine,” he said. “That is the most problematic assumption we find.”
We’re supposed to sleep between seven and 10 hours each night, depending on our age, but the US Centers for Disease Control and Prevention. UU They say that a third of Americans sleep less than seven hours per night. According to World Sleep Day statistics , lack of sleep threatens the health of up to 45% of the world’s population.
“We have ample evidence showing that sleeping five hours a night or less, consistently, increases your risk of suffering adverse health consequences, including cardiovascular disease and early mortality,” Robbins said.
In a longitudinal study of 10,308 British public officials published in 2007, researchers found that those who reduced their sleep from seven to five hours or less per night were almost twice as likely to die from all causes, especially cardiovascular disease.
Science has also linked lack of sleep with high blood pressure, a weakened immune system, weight gain, lack of libido, mood swings, paranoia, depression and an increased risk of diabetes, stroke, dementia and some types of Cancer.
2. It is healthy to be able to fall asleep “anywhere, anytime”
Falling asleep as soon as the car / train / plane starts to move is not a sign of a well-rested person, sleep experts say. In fact, it’s the opposite.
“Falling asleep instantly anywhere, anytime, is a sign that you are not getting enough sleep and that you are falling into episodes of” micro-sleep “or mini-sleep,” said Robbins. “It means that your body is so exhausted that every time you have a moment, you will begin to pay your sleep debt.”
You feel drowsy from the accumulation of a chemical called adenosine in the brain, which develops throughout the day as night falls. Sleeping deeply reduces that chemical, so that when you get up, the levels are at their lowest level and you feel refreshed.
But the longer you stay awake and the less you sleep, the more your adenosine levels will increase, which is what is called a sleep load or a sleep debt.
Do you want to check your level of drowsiness? Look at the Epworth Sleepiness Scale and, if you’re worried, consult a sleep doctor who can perform more extensive tests in a sleep lab.
