Most experts agree on an average of twenty minutes for the perfect nap. But Dr. Kent Smith, D-ABDSM, ASBA, president of the American Sleep and Breathing Academy and the founder of Sleep Dallas, says that it "depends on the reason for the nap, but fifteen to forty-five minutes is considered an optimal duration, as longer than that can put you into a REM cycle, making you feel groggy."
The trick is to avoid entering deep sleep, which takes time. This is why shorter naps are optimal. Smith says, "If you have only five minutes to nap? Go for it. Even that short period has been shown to improve alertness and certain memory processes."
