The Science & Practice of Perfecting Your Sleep

Canon

Walker: exercise is the most potent sleep aid available. It increases deep sleep (slow-wave sleep) more than any pharmaceutical, and it works within one session.

Highlights

Sleep deprivation mimics Alzheimer's pathology — the glymphatic system
Walker: during deep sleep, the glymphatic system clears beta-amyloid and tau proteins from the brain. One night of poor sleep increases beta-amyloid levels measurably. Chronic sleep loss accelerates neurodegeneration.
