REM sleep typically begins 90 minutes after you go to sleep. Usually, the initial REM stage lasts for ten minutes. Your later REM stages develop longer and longer, with the final one sometimes lasting up to an hour. Your breathing and heart rate pick up.
The third stage of your sleep cycle is sleep, sometimes referred to as REM sleep. Small, erratic brain waves, quick eye movements, an elevated heart rate, and paralysis of the muscles are its hallmarks. Your body will spend 90 to 110 minutes in REM sleep the first time it happens at night. Your time in this stage extends throughout the night, especially if you use white noise to keep the tone constant.
Since your brain is more active during REM sleep, you may experience vivid dreams. REM is crucial because it activates brain regions that aid in learning and is linked to an increase in the creation of proteins.
Compared to adults, who only spend around 20% of their sleep in the REM state, infants can sleep for as much as 50% of the time.
