Napping has been found to be beneficial. Napping for 20 minutes can help refresh the [[mind]], improve overall alertness, boost [[mood]] and increase productivity. Napping may benefit the [[heart]]. In a six-year study of [[Greek]] adults, [[researchers]] found that men who took naps at least three times a week had a 37 percent lower risk of [[heart]]-related [[death]]. Napping may also relieve headaches.

[[Scientists]] have been investigating the benefits of napping for years: the 20-minute nap, as well as [[sleep]] durations of 1–2 hours. [[Performance]] across a wide range of [[cognitive]] [[processes]] have been tested. Studies [[demonstrate]] that naps are as [[good]] as a night of [[sleep]] for some types of [[memory]] tasks. A [http://en.wikipedia.org/wiki/NASA NASA] [[study]] led by David F. Dinges, professor at the [http://en.wikipedia.org/wiki/University_of_Pennsylvania_School_of_Medicine University of Pennsylvania School of Medicine], found that naps can improve certain [[memory]] [[functions]] and that long naps are better than short ones. In that NASA [[study]], volunteers spent several days living on one of 18 different [[sleep]] schedules, all in a [[laboratory]] setting. To [[measure]] the effectiveness of the naps, tests probing [[memory]], alertness, response time, and other [[cognitive]] [[skills]] were used.
