Close your eyes and relax for 2 minutes.
How to do it
It doesn't have to be a nap, per se, and it doesn't even have to be on a bed! Try the lounge chair in the den, the sofa in the restroom at work, or even a reclined seat in your car. Set the timer on your watch or cell phone for two minutes. Relax and just close your eyes, and focus on taking deep breaths.
Why it matters
Our body clocks naturally dip into a lull in the early afternoon, or about seven hours after awakening. Quick naps can help you get through the lull without turning to caffeine or sugar. Studies show that naps as short as just 10 minutes can improve performance and alertness, and may also have unexpected health benefits, such as reducing your heart attack risk. Naps any longer than 20 to 30 minutes are said to be less beneficial; they can leave you groggy and interfere with nighttime sleep.
A number of notable figures in history are known to have been regular nap-takers, including Winston Churchill, John F. Kennedy, Leonardo Di Vinci, Thomas Edison, and Albert Einstein.
