9. Immediate Entry into REM Sleep
On average, adults spend about 20% or one and a half hours in REM sleep each night. REM sleep is recognized as one of the most essential stages of the sleep cycle. REM, or Rapid Eye Movement, is the restorative part of our sleep and is when most of our dreaming occurs. Monophasic sleepers spend about 65% in NREM (non-REM) sleep, or light sleep; some polyphasic sleepers believe that light sleep is useless, and thus try to lessen it as much as possible to dive right into a deep REM sleep cycle.
8. Become a Night Owl and Early Riser
Do you find yourself to be a night owl or an early riser? Perhaps you’re stuck in the middle and think you may be a bit of both. With polyphasic sleep schedules, you are able to embrace both night owl and early riser behaviors. Not only are you active in the early morning hours, but you find yourself ready to go once the sun sets as and you finish up one of those power naps.
7. Multiple Brain Breaks Throughout the Day

A polyphasic schedule allows your mind and body to rest for short periods multiple times throughout the day. Imagine having three lunch breaks during your workday? Talk about ideal! With a majority of polyphasic sleeping involving the REM cycle, the brain is restored various times in one single day.
6. Improve Overall Sleep Quality
Let’s be honest; it is best to focus on quality rather than quantity. We’ve all gotten a full 12-hours of sleep and yet have woken up groggy and still tired. Sleeping polyphasically helps to improve sleep density and stability. You can think of a polyphasic schedule as more quality sleep rather than quantity since you are generally getting less sleep than monophasic or biphasic sleepers, but getting an overall stronger sleep.
