Myth: You can catch up on lost sleep on the weekend

Sorry, but you can’t make up for too little sleep by sleeping more on the weekends. A Harvard study found that even if you snooze for an extra 10 hours on the weekend to compensate for only sleeping six hours a night for two weeks, those extra hours won’t improve your reaction times or ability to focus.
