What happens every time we get a bit of shut eye? Sleep occurs in a recurring cycle of 90 to 110 minutes and is divided into two categories: non-REM (which is further split into four stages) and REM sleep. Non-REM sleep. Stage one: Light Sleep. During the first stage of sleep, we're half awake and half asleep. Our muscle activity slows down and slight twitching may occur. This is a period of light sleep, meaning we can be awakened easily at this stage.
What Happens During Sleep? We spend (or at least are supposed to spend) a third of our day sleeping. Sleep is much more than a passive activity; we need that time to clear our minds and restore our bodies. If we donât get enough rest each night, we become cognitively impaired, just as if we had been drinking alcohol.
