To Nap or Not To Nap?

Nap wisely...

If you have trouble sleeping, avoid naps, especially in the afternoon. Power napping may help you get through the day, but if you find that you can't fall asleep at bedtime, eliminating even short naps may help.

When done right, a little daytime snooze won't destroy your nighttime slumber, and can boost memory, alertness and job performance while you're at it. Just make sure you limit yourself to about 10 to 30 minutes and make it during the mid-afternoon.

Tip: Overcome an afternoon energy slump with a short walk, a glass of ice water, or a phone call with a friend.
