The Night Shift: How Sleep Cleans Your Brain

The Glymphatic System
Scientists recently discovered that during sleep, the brain's 'waste management system' turns on. Cerebrospinal fluid (CSF) flows rapidly through the brain to clear out metabolic waste like amyloid-beta. This is why you feel 'foggy' when you don't sleep enough!
