Detailed explanation-1: -During sleep, the body goes through multiple sleep cycles. Each cycle consists of four stages: three stages of non-rapid eye movement (non-REM) sleep and one stage of rapid eye movement (REM) sleep. A person will cycle through the stages of non-REM and REM sleep 4–6 times per night, on average.
Detailed explanation-2: -The idea is to align your bedtime to your 90 minute sleep cycles, so you wake after a complete cycle in REM sleep (when we have structured dreams) and thus feel more refreshed.
Detailed explanation-3: -In a typical night, a person goes through four to six sleep cycles. See Full Reference . Not all sleep cycles are the same length, but on average they last about 90 minutes each.
Detailed explanation-4: -An average sleep cycle lasts about 90 minutes. Ideally, you need four to six cycles of sleep every 24 hours to feel fresh and rested. Each cycle contains four individual stages: three that form non-rapid eye movement (NREM) sleep and one rapid eye movement (REM) sleep.
Detailed explanation-5: -Sleep cycles are around 90 minutes and we tend to go through around five a night.
