Sleep isn’t downtime for your brain. It’s a flush cycle — William Wallace
Sleep isn’t downtime for your brain. It’s a flush cycle.
During sleep, the spaces between brain cells expand ~60%. CSF flows through and washes out metabolic waste, including β-amyloid, the peptide that aggregates in Alzheimer’s. Clearance is ~2x faster than during wake.
Mechanism characterized by Nedergaard’s lab in 2013 (Xie et al., Science). Called the glymphatic system. The brain has no conventional lymphatics. This is the workaround.
Sleep duration is the lever you actually control.
