Sleep is one of the most important aspects of our life, health and longevity and yet it is increasingly neglected in twenty-first-century society, with devastating consequences: every major disease in the developed world - Alzheimer's, cancer, obesity, diabetes - has very strong causal links to deficient sleep.
In this book, the first of its kind written by a scientific expert, Professor Matthew Walker explores twenty years of cutting-edge research to solve the mystery of why sleep matters. Looking at creatures from across the animal kingdom as well as major human studies, Why We Sleep delves into everything from what really happens during REM sleep to how caffeine and alcohol affect sleep and why our sleep patterns change across a lifetime, transforming our appreciation of the extraordinary phenomenon that safeguards our existence.

APPLE BOOKS REVIEW
Irony alert: this book will keep you up at night worrying about how much sleep you’re getting. Neuroscientist Matthew Walker’s must-read book examines America’s “sleep loss epidemic” and “the greatest public health challenge we face in the 21st century.” Walker is a man on a mission, determined to spread the gospel of sleep’s health benefits. Memory retention, mood, creativity, problem-solving skills, disease prevention—it turns out that slumber is the Swiss Army knife of well-being. Exuberant, fact-rich and surprisingly accessible, Why We Sleep also offers useful tips for achieving a better night of shut-eye.
