NREM Stage Four
Are beta waves emitted in Stage 4?
Yes

Microsleep
Sleep protects and helps us recover, restore, and repair brain and body tissure:
Restorative Theory
Sleep helps us remember because it provides our brains with time to restore and rebuild fading memories:
Memory Consolidation Theory
Sleep provides the body with time to grow because the pituitary gland releases the growth hormone while one is asleep:
Growth Theory
