Exhausted from the mid-week slump? Not the folks at Huffington Post, whose office has not one but two nap rooms. Founder Arianna Huffington advocates for all things sleep-related and for good reason — naps can decrease drowsiness, increase alertness and benefit a person's overall health.

As this illustration from Daily Infographic shows, humans consolidate sleeping time for a long period at night, but we're designed to feel tired in the early morning hours and mid-afternoon, when a 2 p.m. nap would feel awesome. A 2- to 5-minute nap can perk you up and a 5- to 20-minute nap can improve your motor skills and performance. Siesta, anyone?
