What are the 4 stages of sleep?

Sleep has been traditionally divided into 4 categories: awake, light, deep, and REM sleep. Each one plays an essential role in maintaining your mental and physical health.

What happens to the body in stage 4 sleep?

By stage 4, the brain almost exclusively produces delta waves. Delta waves promote immune function and help us feel restored. During deep sleep, the body repairs muscles and tissues, stimulates growth and boosts immune function. You won’t experience any eye movement or muscle activity during these stages.

Why does REM sleep decrease with age?

As people get older, they sleep less and wake up more frequently. As the brain ages, neurons and circuits in the areas that regulate sleep slowly degrade, resulting in a decreased amount of non-REM sleep. Since non-REM deep sleep plays a key role in maintaining memory and cognition, that’s a problem.
