The average length of the first NREM-REM sleep cycle is 70 to 100 minutes. The second, and later, cycles are longer lasting—approximately 90 to 120 minutes (Carskadon and Dement, 2005). In normal adults, REM sleep increases as the night progresses and is longest in the last one-third of the sleep episode.

What is the difference between deep sleep and REM?

Deep sleep is often confused with REM sleep but there are differences between the two. This third stage of sleep is non-rapid eye movement sleep.
