Lack of sleep is harmful to health, and productivity. Surely you've heard this many times. But if you can feel that your skills have deteriorated? The answer is no.
In 2004 an interesting experiment was conducted at the University Of Pennsylvania Medical School in Philadelphia, that proves next. 48 adults participated in the study of sleep deprivation. Some of them sleep at two to four weeks reduced the six or eight hours. Others have not slept for two days.
Why six hours of sleep is not enough
As you can imagine, the subjects who slept for eight hours a day, had the best performance of cognitive processes. People who are slept four hours a day every day was acting worse and worse. And those who slept for six hours retain mental capacity at a high level until about the tenth day of the experiment. That's only in the last few days, the subjects performed the test items is as bad as people deprived of sleep in general. It turns out that, just resting for six hours, you are acting just as bad as the people who did not close their eyes for two days. One of the most impressive results of the study is that people should not feel sleepy slept for six hours. If you want to relax a bit – you can visit one of this wonderful top ten webcam sites.
They do not even know how their results have deteriorated.
People deprived of sleep, feel more and more sleepy, and talked about it. At the end of the experiment they wish to sleep in two times higher than at the beginning. But after six hours of sleep the subjects feel a little sleepy. Although, you’re cognitive performance is not much different from person who don’t sleep at all. This finding raises an important question: how people cope with lack of sleep, if they do not even realize it?
We do not know how much we sleep actually
University of Chicago study found that people often overestimate the same amount of sleep as underestimating it. Other research has shown that people overestimate sleep time by an average of 0.8 hours. So if you think you slept seven hours it is quite possible that you are actually rested only six hours. It turns out, no one can say exactly how much he sleeps and when he sleeps enough. All believe that sleeping more than it actually is.
