Compensating sleep debts
Most of us believe that we can recover this so-called “sleep debt” during the weekend if they sleep late on Saturday or Sunday. A new investigation shows that reality couldn’t be further from the truth in this case, e Science News reports.
The research shows that indeed sleeping for 10 hours or more on one weekend night has some beneficial health effects. However, these effects are not, by far, sufficient to compensate for the chronic sleep restriction people have experienced throughout the week. In other words, it takes a lot more than a single night to recover the sleep debt. The conclusion appears in the August 1 issue of the esteemed medical journal Sleep. The investigation was conducted by scientists at the University of Pennsylvania in Philadelphia, who were led by expert David F. Dinges, PhD.
Lifestyles that involve chronic sleep restriction during the workweek and during days off work may result in continuing buildup of sleep pressure and in an increased likelihood of loss of alertness and increased errors say Dinges.
The additional hour or two of sleep in the morning after a period of chronic partial sleep loss has genuine benefits for continued recovery of behavioral alertness. Adequate recovery sleep duration is important for coping with the effects of chronic sleep restriction on the brain, the expert adds.
