Sleep Stages

Sleep isn’t all the same. As we sleep our body enters different stages;  light sleep, deep sleep and R.E.M sleep. It’s important that your body is able to enter each of the stages and complete a full sleep cycle. This will help you to feel fully refreshed and it will help you to learn.

This video has some tricky language in it. It talks about Brain Waves, which is information gathered from a medical machine. You can either a) ignore it or b) do your own research to find out more. Watch it with your teacher, a group of friends or an adult so that you can get the most out of it!

As you’re drifting off to sleep, it doesn’t seem like much is happening . . . the room is getting fuzzy and your eyelids feel heavier and heavier. But what happens next? A lot!


Stage 1


Stage 2


Stage 3


Stage 4


Stage 5: R.E.M


While you’re asleep, you repeat stages 2, 3, 4, and R.E.M. about every 90 minutes until you wake up in the morning. For most kids, that’s about four or five times a night. Who said sleep was boring?
