Thirty people in Harvard University were tested four times a day on how quickly they could process information. They were shown flashing images of diagonal lines on the screen and asked to identify which direction they were slanted. The performance of ten people who stayed awake the entire day declined by 50%, while the people who napped for an hour in the early afternoon did as well as on their last test as on their first. Even those who napped for half an hour did better than the ones who didn't sleep.
