Author's Note: How Sleep Deprivation Works

Tired? A 26-minute nap, it turns out, is a better booster than a cup of coffee (or a few cups of coffee). It can boost your mental performance by as much as 34 percent and your overall alertness by 54 percent for more than three hours post-nap. Jon Stewart may have called insomnia his greatest inspiration, but I have to wonder what he could do if he embraced napping instead.
