Things We Need To Understand About Non-REM and REM sleep cycles
Usually, a person goes through four stages of sleep during a complete sleep cycle. The most important being the Non REM and the REM sleep cycle. Let us check out some details about both these sleep cycles and why they are important.
A normal sleeper goes through four stages of sleep, stage 1,2 and 3 are the Non-Rem sleep and the REM sleep. A sleep cycle is a change that a sleeper goes through from the Non-REM sleep to the REM sleep. First, a sleeper starts with the N-REM sleep and then a shorter period of REM sleep. A sleeper does not go straight to the REM stage of sleep, they first start with light sleep to deep sleep and then return back to a light sleep. The sleep cycle process would be around 4 to 5 cycles throughout the night, which would last for 90 to 120 minutes.
