The process may play a role in preventing neurodegenerative conditions such as Alzheimer’s disease..

What happens to our brains while we sleep?

Specifically, it allows your neurons, or nerve cells, to reorganize. When you sleep, your brain’s glymphatic (waste clearance) system clears out waste from the central nervous system. It removes toxic byproducts from your brain, which build up throughout the day. This allows your brain to work well when you wake up.

What parts of the brain shut down during sleep?

What are the 4 stages of sleep?

During an ideal night’s sleep, your body has enough time to go through four to five 90-minute cycles that sample different phases of sleep as the night progresses. In general, each cycle moves sequentially through each stage of sleep: wake, light sleep, deep sleep, REM, and repeat.
