An afternoon nap can make you smarter

Image result for afternoon napNow there's a new reason to enjoy a snooze: An afternoon nap can make you smarter. Researchers gave memory tests to 39 adults at noon and then again at 6pm. Half took a 90 minute nap between the tests. Those who remained awake performed about 10 percent worse than those who napped. Most people's ability to learn declines about 10 percent between noon and 6pm, but the nappers were able to overcome that decline, discovered researchers at the University of California, Berkeley. "Sleep is not just for the body," says Dr. Matthew Walker, author of Why We Sleep. "It's very much for the brain."
