Your brain and body will go through a different cycle of sleep when you fall asleep, and each cycle includes five distinct stages.
Adults need to complete at least 5 or 6 sleep cycles per night. On average, you may need 10-20 minutes to fall asleep, and it takes about 90 minutes to go through each sleep cycle.
Five cycles are about 7.5 hours of sleep a night, while six full cycles are about 9 hours of sleep. Ideally, you usually feel more refreshed when you wake up at the end of a sleep cycle.
Sleeping time are based on your wake-up time, five or six complete sleep cycles and 15 minutes to fall asleep.
