Identify the benefits of sleep

Identify the benefits of sleep. Please include the stages of sleep and any specific benefits that are identified with a specific stage.

What is the importance of sleep and sleep stages?
Each sleep stage plays a part in allowing the mind and body to wake up refreshed. Understanding the sleep cycle also helps explain how certain sleep disorders, including insomnia and obstructive sleep apnea, can impact a person’s sleep and health
What are the benefits of Stage 2 sleep?
In stage 2, brain wave continues to slow with bursts of rapid brain activity called sleep spindles and K complexes. These bursts are thought to play a role in long term memory consolidation and sensory processing, and to protect the brain from waking up from sleep. Body temperature decreases and heart rate slows down.
