Brains Cleans Toxins During Sleep

[shahina]

While the brain sleeps, it clears out harmful toxins, the flow of cerebrospinal fluid in the brain increases and washes away harmful waste proteins that build up between brain cells during waking hours.

The scientists noticed that during sleep, the system that circulates cerebrospinal fluid through the brain and nervous system pumps fluid into the brain and removes fluid from the brain in a very rapid pace. During sleep brain cells shrank, making it easier for fluid to circulate.
