PSYCHOLOGY OF EMOTIONS

Detailed explanation-1: -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-2: -Our sleep cycles are made up of different stages, and it’s crucial to complete a full cycle for optimal muscle gains and recovery, and mental rejuvenation and well-being. And cycles of 90 minutes of sleep seem to be the perfect amount of time to complete a full sleep cycle.

Detailed explanation-3: -Ideally, you should try to get more than 90 minutes of sleep. Sleeping between 90 and 110 minutes gives your body time to complete one full sleep cycle and can minimize grogginess when you wake.

Detailed explanation-4: -Each cycle lasts 90 minutes on average, and the recommended sleep time for adults is 7-8 hours. You can fit five complete 90-minute cycles during that time. If you sleep more or less, you risk interrupting these cycles and not resting well enough.

Detailed explanation-5: -A full sleep cycle takes about 90 to 110 minutes. Your first REM period is short. As the night goes on, you’ll have longer REM sleep and less deep sleep.
