The Stanford researcher Cheri D. Mah found that when she got male basketball players to sleep 10 hours a night, their performances in practice dramatically improved: free-throw and three-point shooting each increased by an average of 9 percent.
Daytime naps have a similar effect on performance. When night shift air traffic controllers were given 40 minutes to nap — and slept an average of 19 minutes — they performed much better on tests that measured vigilance and reaction time.
Longer naps have an even more profound impact than shorter ones. Sara C. Mednick, a sleep researcher at the University of California, Riverside, found that a 60- to 90-minute nap improved memory test results as fully as did eight hours of sleep.
Research confirms that, counterintuitively, relaxing makes you more productive. Of course, Thomas Edison knew that sleep is the key to success.
