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.
Well, take it. In honor of the beginning of daylight-savings time, and the end of National Sleep Awareness Week, today is National Workplace Napping Day. So go ahead. By most accounts, you'll be a better, more productive worker and a healthier person. Bush is in good company.
