Are you fresh when you get up in the morning? If not, it is a sign that you have not slept enough.

On the other hand, it is not so obvious that it can be harmful not to sleep enough, despite the fact that you feel fresh. It's the american ­sleep doctor Lawrance j. Epstein of Harvard Medical School, who, among other things. is for the father of the book "Guide to a Good night's Sleep", which draws attention to this problem.

The exact sleep ­ needs vary, but as a starting point, the adults need 7-10 hours of sleep each night.

Researchers from the University of Pennsylvania has previously conducted experiments in which participants only got 6 hours sleep every night for 2 weeks. At the end of this experiment, it turned out that brain activity was similar to that of a person who hadn't slept for 2 whole days.

Sleep is important as it is the time where your body and cells get to grow, regenerate and repair themselves.
