1. Napping is only for the lazy -- or those under 5. A short snooze can boost everything from alertness and memory to creativity and productivity.
2. If I take a nap, I'll only wake up feeling worse. Experts generally agree that a nap should last no longer than 30 minutes. Next time you're in the mood for a snooze, set your alarm for 20 to 30 minutes, tops.
3. You definitely shouldn't nap at work. More and more employers come around to the idea that a well-rested workforce is a more productive workforce. If your office doesn't offer a place to lay your head, try to find an empty conference room where you can close a door and dim the lights. Take a snooze on your lunch break in your car.
