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). [29]
Naps: students taking a nap of one to two hours in the early evening hours (between 6:45–8:30 p.m.) had no cortisol awakening response, suggesting cortisol awakening response only occurs after night sleep. [12] Waking up in the light: cortisol awakening response is larger when people wake up in light rather than darkness. [14] [15]
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.

The timing of sleep in humans depends upon a balance between homeostatic sleep propensity, the need for sleep as a function of the amount of time elapsed since the last adequate sleep episode, and circadian rhythms which determine the ideal timing of a correctly structured and restorative sleep episode. The homeostatic pressure to sleep starts ...
The nap trial begins when the lights are turned off. [9] The patient is asked to perform simple tasks to test that the equipment is working properly. The patient is asked to nap for 20 minutes, and then is awakened. The nap process is repeated every 2 hours for a total of four or five times.
