Sleep more when you train

"1/3rd of Americans get 6 hours of sleep a night or less when they really need at least 8 1/2," says James Mass, Ph.D. If you are training, says Maas, shoot for 9 hours. Between the 7th and 8th hour, you go into your last phase of REM sleep. "That's when your mind really restores and repairs itself," he says. Miss that phase and your reaction time and concentration suffer. The best way to work up to the right amount of sleep is to add 15 minutes a night until you start waking up feeling alert and energized all day. Bicycling Magazine, Nov 2001
