The first nap bar in Texas is opening next month in Houston. The nap bar’s target clients are modern day professionals, entrepreneurs and globetrotters. Experts say napping can boost creativity, memory, alertness and overall productivity. The owner says she got the idea after doing a wellness workshop with NASA employees. NASA did a sleep study on weary pilots, and she learned that a 26-minute power nap helped improve their performance and alertness by 54 percent.
