How Sleep Cleanses Your Brain and Helps Reduce Dementia Risk

Are you tracking your sleep quality each night?

Here’s one reason to keep an eye on this important metric: Your sleep quality may impact your brain's ability to efficiently wash away waste products.

As you rest, your brain goes to work clearing proteins and toxins that accumulate during the day—a process that may help lower the risk of dementia.

There’s long been a connection between poor sleep and dementia, but the potential explanation wasn’t found until 2012. That’s when scientists discovered the glymphatic system, a waste clearance system for our central nervous system.

How it works:

  • While you’re awake, proteins called amyloid-betas accumulate in the brain. 

  • These proteins are toxic to neurons in the brain and their accumulation has been linked to a higher risk of dementia.

  • While you sleep, your brain flushes these amyloid-betas, preventing them from forming into plaque.

  • Scientists believe that this system works more efficiently when you’re in deep, non-REM sleep.
