How our bodies clear toxins from our brains while we sleep, scientists explain


Synchronized brain waves of non-REM sleep might prevent toxins from accumulating in a person's brain.
Study done in 2013 on mice showed that while the rodents slept, toxins like beta-amyloid got swept away.
Study participants had to lie down and fall asleep inside an MRI machine.
Participants wore an EEG cap so researchers could look at the electrical currents flowing through their brains.
During non-REM sleep, large, slow waves of cerebrospinal fluid were washing over the brain.
Study could have clinical applications for treating Alzheimer’s.

Cerebrospinal fluid might be involved in the process of cleaning out the toxins
