Sleep is fundamental to our health, longevity, and overall well-being, yet it is increasingly undervalued in modern society. This book, authored by a leading scientific expert, delves into twenty years of research to uncover the critical importance of sleep. It examines sleep across the animal kingdom and in human studies, exploring topics from REM sleep to the effects of caffeine and alcohol, and how sleep patterns evolve throughout life.
