Here's Why You Should Drink Coffee Before You NapA leading sleep expert says caffeine actually helps high-performing people feel more rested, as long as they don't nap too long.

Caffeine is known to stave off sleep, but some experts say drinking a cup of Joe right before taking a 25-minute nap will make you feel more rested.

"I call it a Nap A Latte," says Michael Breus, Ph.D. (akaThe Sleep Doctor), a clinical psychologist and fellow of The American Academy of Sleep Medicine. "Get a cup of black drip coffee, throw three cubes in it merely to cool it down, slug it as fast as you can, and take a nap immediately."
