The new findings were presented this week in San Antonio, Texas, at a meeting of the Associated Professional Sleep Societies.
A separate study found that more sleep may even make a person run faster. The study was small -- seven players on the Stanford University football team. For the study, they aimed for at least ten hours of sleep each night during the season.
After seven to eight weeks of more sleep, the players ran faster in short training races. They also felt less sleepy during the day.
Stanford sleep researcher Cheri Mah says sleep should be part of an athlete's training program. This is some of her advice: Before competition, extend your nightly sleep for several weeks to reduce a sleep debt. Adults should try to get seven to eight hours of sleep a night. Teenagers and young adults should aim for nine hours or more. Go to bed and wake up at the same times every day. And take brief naps during the day to get extra sleep.
