The Science of Sleep

Most people fall into the category called “monophasic sleepers” because they sleep once a day. Then there are a few people that fall into the “biphasic sleeper” category as they sleep two times a day, usually taking a nap in the afternoon, and then there’s “polyphasic sleepers” meaning people that sleep more than two times a day.

“But why would they do that?”, you may say, “It seems like such a waste of time.”

Well, what if I told you it’s not? It actually saves time.

Polyphasic sleeping is a series of schedules one must follow in order to sleep less without experiencing sleep deprivation and it does that by prioritizing quality of sleep over quantity.

But first, let’s talk about sleep, shall we?

Sleep is divided into two categories: REM sleep and non-REM sleep.

REM sleep or Rapid Eye Movement is the sleeping stage in which you dream and it’s called like that because people noticeably move their eyeballs behind their eyelids during this stage in a rapid manner. Yes, you do it too!

Non-REM sleep is also divided into two stages:

The first one is SWS (Slow Wave Sleep) or Delta Sleep and it’s the stage in which your brain has the least brain activity/ slowest frequency (Delta waves). During this stage it is hard or impossible to wake someone up and for that it is also called “deep sleep”. This is also when your body repairs tissues, builds bone and muscle, and strengthens the immune system.
