Why sleep 6 hours a day as bad as no sleep at all
The habit of sleeping only six hours is as bad for your health and productivity as a few sleepless nights. Except you don’t even notice it…
Lack of sleep is harmful to health, and for productivity. You’ve probably heard about it many times. But if do you feel that your skills have deteriorated? It turns out, no.
In 2004, at the medical school of the University of Pennsylvania in Philadelphia conducted an interesting experiment to prove it. 48 adults were involved in the research of sleep deprivation. The sleep from two weeks was reduced to four, six or eight hours. Other haven’t slept for two days.
All this time the group of subjects was tested be the researchers every two hours in the laboratory (with the exception of the hours allotted for sleep), checked cognitive function and reaction time. They were also asked how they themselves assess their condition, how sleepy they were feeling.
Why six hours of sleep is not enough
As you know, the group of subjects who slept eight hours a day, had the best performance of cognitive processes. People who slept four hours a day, every day thinking worse and worse.
And those who slept for six hours kept mental abilities at a high level until about the tenth day of the experiment. That’s only in the last few days, these subjects performed the test task is just as bad as people deprived of sleep at all.
It turns out that, resting only six hours, you are as bad as the people two days in a row not closing eyes.
One of the most impressive results of the research — the fact that people who slept for six hours did not feel sleepy themselves. They didn’t even know how much worse their results.
People deprived of sleep felt more and more sleepy and talked about it. At the end of the experiment, they wanted to sleep in two times more than in the beginning. But after six hours sleep, the subjects felt only a little sleepy. Although their performance cognitive performance did not differ from that of those who didn’t sleep.
This discovery raises an important question: how do people cope with the lack of sleep if they don’t even know what it is?
We do not know how we sleep actually
A study of the University of Chicago showed that people often overestimate the amount of sleep as underestimating him. Another study showed that people overestimate the sleep time on average 0.8 hours.
So, if you think that you have slept seven hours, it is possible that, in fact, you have slept for only six hours.
Turns out, no one can say exactly how much he sleeps and when you sleep. All believe that sleep more than it actually is.
To determine how much you sleep is not as easy as it seems. But there are a few common tips that will definitely help you sleep better:
- Go to bed at the same time.
- Do not use the gadgets for half an hour before bedtime.
- Do not drink alcohol.
- Add physical activity throughout the day.
Another tip, which is less common: to sleep better, you need to lose weight. According to BestAdvisor, evening jogging promotes weight loss.
