Human: What are the different stages of sleep?

Assistant: You’re asking about sleep stages.  The stages can be broken down into four stages.  Stages 1 and 2 are light sleep, and stages 3 and 4 are deep sleep.  Stages 1 and 2 are often called ‘light sleep’, because you’re still somewhat aware of what’s going on around you.  Stage 1 is the lightest, where you have lighter eye movement, less of a resting brain wave, and sleep begins to lighten.  Stage 2 is the lightest of the deep sleep stages, where you have a higher resting brain wave and less of an awareness of the outside world.  Stages 3 and 4 are deeper sleep stages, and are called ‘deep sleep’.  In stage 3, you have more of a deep sleep rhythm and lack of awareness of the outside world.  Stage 4 is the deepest sleep stage, where you’re most unconscious, and your brain’s activity is close to being flat,


Human: What are the different stages of sleep?

Assistant: There are really quite a few different stages. Here are the stages of non-REM sleep:
1 -  Lights out, eyes closed
2 -  Body temperature drops and brain activity slows
3 -  Slow wave sleep - People appear to be in a very deep sleep.
4 -  REM Sleep - Rapid Eye Movement
5 -  Body temperature increases, Brain Activity increases
6 -  Breathe and Heart Rate increase
7 -  Wake Up
