Learn How To Sleep Better By Understanding Sleep Cycles Stages 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 sleep cycle is the period of time when your brain and body rotate through sleep stages, moving from light to deep sleep to rem sleep. in a typical night, most people go through four to six sleep cycles, each lasting between 80 and 110 minutes. the four stages of sleep occur in one of two phases: non rapid eye movement (nrem) sleep and rapid.
Understanding The Sleep Cycle Stages Of Sleep Infographic Stage 3. stage 3 sleep is also known as n3 or deep sleep, and it is harder to wake someone up if they are in this phase. muscle tone, pulse, and breathing rate decrease in n3 sleep as the body relaxes even further. the brain activity during this period has an identifiable pattern of what are known as delta waves. Sleep needs change with age as shown on the chart above. initially, babies sleep 16 18 hours a day. school age children and teens need about 9.5 hours of sleep each night. most adults require 7 9 hours of sleep at night. however, older adults (age 60 and above) tend to sleep for shorter periods at night. Stage 4 is rem sleep. – stage 1 n1: this is the “dozing off” period, which typically lasts one to five minutes. the body hasn’t fully relaxed yet, and it’s easy to wake up during this time. – stage 2 n2: this is when the body enters a more relaxed state; temperature drops and breathing and heart rate slow. Rem. stage 4. rem sleep. 10 60 minutes. in stage 1, you’ve just dozed off and started transitioning to stage 2, which involves further slowing of activity in the brain and body. it’s much easier to be awoken during these early stages of the sleep cycle. stage 3 is the deepest part of nrem sleep. in this stage, your muscles and body relax.

As you sleep, your brain cycles through four stages of sleep. the first three are considered non rapid eye movement (nrem) sleep, also known as quiet sleep. the fourth is rapid eye movement (rem) sleep, also known as active sleep. each sleep stage has a unique function and role in maintaining your brain’s overall cognitive performance. 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.
