A growing body of evidence suggests that employers should seriously consider to install nap rooms in their offices. A new University of Michigan study finds that taking a nap may be an effective strategy to counteract impulsive behavior and to boost tolerance for frustration. The researchers investigated the effects of a nap in a group of 40 study participants, divided in a group that was allowed to take a 60-minute nap during work-time, and a group that was not. It turned out that the nap group was more patient when it came to completing difficult computer tasks, taking their time solving any issues that came up compared to the non-nappers.
