The 20-minute power nap -- sometimes called the stage 2 nap -- is good for alertness and motor learning skills like typing and playing the piano. What happens if you nap for more than 20 minutes? Research shows longer naps help boost memory and enhance creativity.
Aim to nap for only 10 to 30 minutes. The longer you nap, the more likely you are to feel groggy afterward. Take naps in the afternoon. The best time for a nap is usually midafternoon, around 2 or 3 p.m. This is the time of day when you might experience post-lunch sleepiness or a lower level of alertness. In addition, naps taken during this time are less likely to interfere with nighttime sleep.
