In some places, towns essentially shut down in the afternoon while everyone goes home for a siesta. Unfortunately, in the U.S.—more bound to our corporate lifestyles than our health—a mid-day nap is seen as a luxury and, in some cases, a sign of pure laziness. But before you feel guilty about that weekend snooze or falling asleep during a movie, rest assured that napping is actually good for you and a completely natural phenomena in the circadian (sleep-wake cycle) rhythm.
As our day wears on, even when we get enough sleep at night, our focus and alertness degrade. While this can be a minor inconvenience in modern times, it may have meant life or death for our ancestors. Whether you are finishing up a project for work or hunting for your livelihood, a nap can rekindle your alertness and have your neurons back up and firing on high in as little as 15 to 20 minutes.
Big name (and high-dollar) companies recognize this. Google and Apple are just a few that allow employees to have nap time. Studies have affirmed thatshort naps can improve awareness and productivity. Plus, who wouldn’t love a boss that lets you get a little shut-eye before the afternoon push?
A study from the University of Colorado Boulder found that children who missed their afternoon nap showed less joy and interest, more anxiety, and poorer problem solving skills than other children. The same can be seen in adults that benefit from napping.
Researchers with Berkeley found an hour nap to dramatically increase learning ability and memory. Naps sort of provide a reboot, where the short term memory is cleared out and our brain becomes refreshed with new defragged space.
