New page

* Sleep is entered through NREM sleep.
* Sleep cycles of 90 minutes, 4-6 cycles per night sleep.
* [[Non-REM 3]] predominates in the first third of the night and is linked to the initiation of sleep.
* [[REM sleep]] predominates in the last third of the night

* Wakefulness in sleep usually accounts for less than 5% of the night.
* [[Non-REM 1]] sleep approximately 2% to 5% of sleep.
* [[Non-REM 2]] sleep approximately 45% to 55% of sleep.
* [[Non-REM 3]] sleep approximately 15% to 20% of sleep.
* Non REM sleep, therefore, is usually 75% to 80% of sleep.
* [[REM sleep]] is usually 20% to 25% of sleep, occurring in four to six episodes.
