Detailed explanation-1: -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.
Detailed explanation-2: -As the night goes on, REM stages get longer, especially in the second half of the night. While the first REM stage may last only a few minutes, later stages can last for around an hour. In total, REM stages make up around 25% of sleep in adults.
Detailed explanation-3: -Getting an unusually large amount of REM sleep in a given night is often an indication that you are sleep deprived. Your body routinely gets most of its REM sleep later in the night, during the final hours that you are asleep.
Detailed explanation-4: -Babies spend more time in REM sleep and their sleep cycles are shorter than adults. Time spent in REM sleep decreases and sleep cycles get longer as kids get older.
