This test measures whether a person can stay awake during a time when she or he is normally awake. [ 2 ] [ 4 ] Like the MSLT, the MWT is performed in a sleep diagnostic center over 4 - 5 nap periods. A mean sleep onset latency of less than 10 minutes is suggestive of excessive daytime sleepiness.
The 'maintenance of wakefulness test' (MWT) is a test that measures the ability to stay awake. [45] It is used to diagnose disorders of excessive somnolence, such as hypersomnia, narcolepsy or obstructive sleep apnea. [45] [46] During that test, patients sit comfortably and are instructed to try to stay awake. [45]
The Maintenance of Wakefulness Test (MWT) measures a person's ability to stay awake for a certain period of time, essentially measuring the time one can stay awake during the day. The test isolates a person from factors that can influence sleep such as temperature, light, and noise.

Process S represents the drive for sleep, increasing during wakefulness and decreasing during sleep until a defined threshold level, while Process C is the oscillator responsible for these levels. When being sleep deprived, homeostatic pressure accumulates to the point that waking functions will be degraded even at the highest circadian drive ...
The test is based on subjectivity and therefore may not be accurate when factors such as: the test takers opinions on their sleep, how others view their sleepiness, education level, and others are considered. [11] The test can be biased as pre-emptive discussion of results can have an effect on the responses while the test is being taken. [4]
A second wind may come more readily at certain points of the circadian (24hr) biological clock than others.. Second wind (or third wind, fourth wind, etc.), a colloquial name for the scientific term wake maintenance zone, is a sleep phenomenon in which a person, after a prolonged period of staying awake, temporarily ceases to feel drowsy, often making it difficult to fall asleep when exhausted.
The word is formed from "alert", which comes from the Italian all'erta (on the watch, literally: on the height; 1618). [citation needed] Wakefulness refers mainly to differences between the sleep and waking states; vigilance refers to sustained alertness and concentration. Both terms are sometimes used synonymously with alertness.
