The brain is more useful for a vacation day

Many people who sleep on weekdays, no more than six hours, then expect to catch up and catch up on sleep on the weekends. But scientists warn that compensate for the lack of sleep for the body so it does not turn.

No matter how much you do not sleep on Saturdays and Sundays, it still does not help your body to endure the stress of the "lack of sleep" working days, as scientists have found in the US. Our activities are getting worse if we do not get eight hours night sleep . And the two "full" nights a week does not change the situation.

Long leaves in night sleep on weekends a few clears the brain, but not drastically improve the situation - we still remain inhibited and awkward. American researcher Alexandros Vgontzas Medicine from the College of Staten Penn in Pennsylvania, sleep expert and professor of psychiatry, has attracted a number of young men and women as volunteers. 13 consecutive days, they slept in his laboratory.

The first four nights of the study participants received a full eight hours of sleep, then no more than six hours for six days, and at the end of the three "ten-hour" night. During the day they worked in the usual way, and work performance   these people was recorded by scientists.

"After one working week to six-hour period of sleep was followed by two reducing night - says Professor Vgontzas. - It has helped people get rid of the feeling of drowsiness, but had no effect on their overall activity. Thus, it is safe to say that attempts to catch up on output are useless. It is necessary to put to bed the amount of time every day. "

For those who still can not get at night for more than six hours of sleep, scientists are advised to find time during the day. Breaks slumber lasting 30-40 minutes is very important and refresh the brain increase   work performance .
