Don't nap too close to bedtime. It can disrupt your nighttime slumber. Don't nap if you're an insomniac or have a sleep disorder. The extra zzz's might satisfy last night's sleep loss, but they cut into your sleep requirement for that evening. Opt for a nap instead of a coffee break.
Some sleep is better than none.

A quarter of the population never naps, and 30 percent nap more than four times a week. Scientists say it takes as little as 15 minutes to rejuice our batteries for the next three to four hours. Still, we're a country in need of some zzz's.
