Each individual nap should be long enough to provide at least 45 continuous minutes of sleep, although longer naps (2 hours) are better. In general, the shorter each individual nap is, the more frequent the naps should be (the objective remains to acquire a daily total of 8 hours of sleep). [28]
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.

It is used to measure the time it takes from the start of a daytime nap period to the first signs of sleep, called sleep latency. Subjects undergo a series of five 20-minute sleeping opportunities with an absence of alerting factors at 2-hour intervals on one day.
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. [45] 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.
