A power nap, also known as a Stage 2 nap, is a short slumber of 20 minutes or less which terminates before the occurrence of deep slow-wave sleep, intended to quickly revitalize the napper. The expression "power nap" was coined by Cornell University social psychologist James Maas. [2] The 20-minute nap increases alertness and motor skills. [2]
A nap is a short period of sleep, typically taken during daytime hours as an adjunct to the usual nocturnal sleep period. Naps are most often taken as a response to drowsiness during waking hours. A nap is a form of biphasic or polyphasic sleep, where the latter terms also include longer periods of sleep in addition to one period. For years ...
He is best known for coining the term "power nap". [1] He holds a B.A. from Williams College and an M.A. and Ph.D. from Cornell University. Maas has also produced numerous film specials on sleep research for PBS, BBC, and others. For 48 years, Maas taught psychology as a professor at Cornell University. [2]
There’s nothing like a midday nap to recharge your batteries. It can give you more energy to do the things you love. But the perks go even further: A nap can be good for your brain. “Sleep and ...

Longer naps were found to be better, with some cognitive functions benefiting more from napping than others. Vigilance and basic alertness benefited the least while working memory benefited greatly. Naps in the individual subjects' biological daytime worked well, but naps in their nighttime were followed by much greater sleep inertia lasting up ...
The optimal nap duration is around 10–20 minutes, as researchers have proven that it takes at least 30 minutes to enter slow-wave sleep, the deepest period of sleep. [44] Napping too long and entering the slow wave cycles can make it difficult to awake from the nap and leave one feeling unrested. This period of drowsiness is called sleep inertia.
However, Winter says that naps will likely help, too. "Any sleep counts, although sleep that is regular in its scheduling is far more effective," he says. "So trying to nap 'on a schedule' can ...
