If so, you’re in good company. According to the National Sleep Foundation, John F. Kennedy, Winston Churchill, Napoleon, and Albert Einstein each fancied afternoon naps. Youngsters nap, and so do many seniors. But by and large, humans are part of the minority of mammals that do not sleep for short periods of time throughout the day, instead dividing their days between sleep and wakefulness. However, there are some benefits to catching a midday snooze. The Mayo Clinic says napping can be a way to catch up on sleep lost during the night or if a person is feeling sleep-deprived. It also may be a way to relax, increase alertness and improve mood. Naps should take place before 3 p.m. and not exceed 20 minutes. The longer and later one naps, the greater the potential it will interfere with nighttime sleeping or backfire and cause daytime grogginess.
