Just when we think coffee can’t get any more miraculous, here comes the coffee nap.
It sure seems like an oxymoron. How is it possible to pair up getting wide-eyed with getting shut-eye?
It works like this: In the afternoon when fatigue sets in, you drink a cup of coffee, set your alarm for 20 to 30 minutes, then doze off. That's the perfect amount of time to let the caffeine kick in. You'll wake up alert and refreshed. Science says so.
