Why We Sleep | Matthew Walker

Why it is here:

This book destroys the myth of the "sleepless hustler."

Walker, a neuroscientist, provides the non-negotiable biology of rest.

He reveals that sleep is not a period of dormancy, but an active "cleaning cycle" where the glymphatic system flushes out neurotoxins (like amyloid plaques) and the brain consolidates memory and emotional regulation.

We include this because a thriving culture often treats sleep deprivation as a badge of honor.

Walker provides the scientific ammunition to treat sleep as a Performance Enhancing Drug.

It proves that getting 8 hours is not a luxury or a sign of weakness; it is the biological cost of sanity.

Without it, empathy, creativity, and immune function all collapse.
