Scientists have long known that sleep is essential for memory, but only recently have they understood how it works. During deep sleep, the brain replays the day's experiences, transferring them from short-term to long-term storage. People who sleep less than six hours a night consistently perform worse on memory tests than those who sleep seven to eight hours.
