is a nap the same as meditation?
A study two years ago, led by Prashant Kaul of the University of Kentucky does some way to prove that they are. Following a series of tests, when the researchers tested the alertness of volunteers, they found that meditation proved more effective than naps, exercise or caffeine.
Actually, naps are good for most people, Mednick says. Her research shows a napâdefined as daytime sleeping that lasts between 15 and 90 minutesâcan improve brain functions ranging from memory to focus and creativity. âFor some people, naps are as restorative as a whole night of sleep,â she adds.
