Stage 5 - REM Sleep: REM sleep usually occurs in cycles during the last 5-6 hours of an 8-hour nightâs sleep. So how much sleep we get in this stage will depend on how much sleep we get for the night. During REM sleep, eye movements increase, heart rate increases, and the normal body processes also increase.
Typically, a 5- to 10-minute period of N2 precedes the initial REM sleep episode. REM sleep comprises about 20 to 25 percent of total sleep in typical healthy adults. NREM sleep and REM sleep continue to alternate through the night in a cyclical fashion. Most slow-wave NREM sleep occurs in the first part of the night; REM sleep episodes, the first of which may last only one to five minutes, generally become longer through the night.
