Guilty about that afternoon nap? Don't be. It's good for you.

You may be familiar with that feeling of overwhelming sleepiness during the mid-afternoon. It's common, occurs whether you've eaten lunch or not, and is caused by a natural dip in alertness from about 1 to 3pm. So, if you find yourself fighting off sleep in the middle of the day and you're somewhere where you can have a nap, then do it.
Taking the time for a brief nap will relieve the sleepiness almost immediately and improve alertness for several hours after waking. And there are many other benefits too.
