American researchers have dispelled the myth that a long weekend sleep can compensate for the lack of sleep during the work week. Moreover, according to scientists, people who sleep on Saturday longer than usual, then do not get enough sleep during the week. It is especially difficult for them to get up on Monday morning.
Dr Gregory Carter, a sleep medicine specialist at the University of Texas Southwestern Medical Center in Dallas, says that a person has daily, or circadian, cycles that control the body’s internal clock.
People can turn their hands on their circadian clock for 1 hour, sleep 1 hour longer on the long-awaited weekend, but the problem is that after a long sleep on the weekend, the circadian clock of the brain can "lag" up to two 2 hours. As a result, it is difficult for a person to fall asleep on Sunday at the usual time, and even more difficult to wake up on Monday morning.
“In order to maintain our internal biological clock in good condition, we need to go to bed 8 hours before our usual time of getting up in the morning,” the researcher said in his speech. “Too many of us go to bed later on Friday and Saturday and sleep in the morning on Saturday and Sunday. This lifestyle, combined with other behavioral factors that interfere with sleep, which may include alcohol consumption or checking your email just before bedtime, makes our awakening on Monday painful. "
Carter says it’s much more effective to go to bed early than to get up later.
