I love to sleep in on the weekends (when Tabs lets me), and when I get a few extra hours of shuteye, I feel like a brand new girl!
But a recent study published in the journal Sleep suggests that getting a little extra rest on one of the weekend days, while helpful, may not fully make up for a week of inadequate sleep.
Behavioral, subjective and physiological measures of alertness improved significantly after a night of recovery sleep, with larger doses of sleep producing greater gains. Yet some neurobehavioral deficits continued to linger after the maximum recovery dose of 10 hours in bed, during which participants slept for an average of about nine hours. The study suggests that complete recovery from sustained sleep restriction may require even more sleep during one night or multiple nights of extended sleep. -source
The body’s circadian rhythm will probably prevent a lot of people from even getting much more than 8-10 hours in one fell swoop. A better recipe for catching up on sleep may be to shoot for an extra hour on both days of the weekend, as opposed to two extra hours just once.
Wha? More sleep is better than less? I know — it may not be particularly groundbreaking, but the research shows that recovery from a bout of bad sleep isn’t as simple as previously thought.
The effects of sleep depravation can be dramatic, so try to get some extra shuteye as often as you can. Not getting enough doesn’t just darken under-eye circles (GAH!), it also dramatically impairs alertness, attention span, and can even increase your risk of heart disease.
