Research shows that the more hours you work continuously, the greater the toll on your performance. So you could greatly improve your productivity by leaps and stay sharper just by grabbing a few Zzzzzzzzs…

Think taking a nap at work is crazy? Here are three ways to make it happen:

Schedule a time. Between 1 p.m. and 3 p.m. is the best time. Mark it in your calendar so you are more likely to take it.

Find a quiet place. Close your door and put up a "do not disturb" sign. If you work in a cubicle, look for a conference room, or a local coffee shop or library. (Really? People do this in public?)

Tune out. Turn off your technology and set an alarm for 20 or 30 minutes (longer naps can leave you hazy). Close your eyes and breathe deeply. Even if you don't fall asleep, this relaxation will ensure you rest.

Of course, you'll probably have to sell the idea to your boss first…

What's the weirdest thing you've ever done at work?
