How to Catch Up On Sleep Sleep is a precious commodity for most of us. Many don't get enough during the work week, so they try to make up for it during the weekends. Recent research shows that catching up on sleep won't undo the damage already done. It is common knowledge that being sleep-deprived is not good for someone's health, but a new study mimics how a lot of people live. For five days, volunteers were only allowed six hours of a sleep each night. Then for two days, they were allowed to sleep in, getting a solid 10 hours a night. During that time, researchers measured their stress and inflammation as well as performance levels and found that sleeping in doesn't really help. The study shows that after being sleep-deprived for five days, and getting two days of "recovery" sleep, your performance does not improve back to baseline.
