Why We Sleep

Matthew Walker

Why We Sleep examines what sleep does, how circadian timing and accumulating sleep pressure organize it, and what happens when modern life fragments it. It connects sleep with memory, emotion, health, development, and dreaming, then considers practical and institutional changes that could restore sleep’s place in daily life.
