Hi Vickie

Thanks for your question! 

There are several stages in sleep, divided in REM sleep and non REM sleep. REM stands for Rapid Eye Movement. 

REM sleep is our lighter sleep, happening closer to when we first fall asleep rather than hours into it. We can wake more easily at this time because our brains haven't really shut down as much as it does after several hours. 

After about two to three hours we move into a much deeper sleep that has four parts, each becoming a deeper sleep. 

Stage 4 of non REM sleep is the deepest kind of sleep you can be in. Have you ever been woken up and found it hard to focus and understand what's going on for a few minutes? That's stage 4. 

Has this helped?

That's interesting, Vicki. 

Was this concluded from a sleep lab that you attended? 

Is you life affected by this?
