Many people skimp on sleep during the week and try to make up for lost time on the weekend. But a study published February 28 in Current Biology shows this strategy won’t necessarily reverse the ill effects of sleep deprivation on your body.
The study, conducted in a sleep lab, tested the health effects of three sleep strategies over a two-week period. Participants in one group were allowed to sleep up to nine hours a night. Those in a second group were limited to five hours a night. People in the third group slept five hours nightly during the week, but were allowed to sleep in on Saturday and Sunday.
