Why We Sleep

This book delves into the purpose and power of sleep, explaining how it affects every aspect of our physical and mental well-being.

Walker discusses how sleep enriches our ability to learn, memorize, and make logical decisions, recalibrates our emotions, restocks our immune system, fine-tunes our metabolism, and regulates our appetite.

He also explores the consequences of sleep deprivation and provides actionable steps to improve sleep quality, including ways to prevent cancer, Alzheimer’s, and diabetes, slow the effects of aging, and increase longevity.
