Why We Sleep: Unlocking the Power of Sleep and Dreams by Matthew WalkerA New York Times bestseller
The first sleep book by a leading scientific expert—Professor Matthew Walker, Director of UC Berkeley’s Sleep and Neuroimaging Lab—reveals his groundbreaking exploration of sleep, explaining how we can harness its transformative power to change our lives for the better.
Sleep is one of the most important but least understood aspects of our life, wellness, and longevity. Until very recently, science had no answer to the question of why we sleep, or what good it served, or why we suffer such devastating health consequences when we dont sleep. Compared to the other basic drives in life—eating, drinking, and reproducing—the purpose of sleep remained elusive.
An explosion of scientific discoveries in the last twenty years has shed new light on this fundamental aspect of our lives. Now, preeminent neuroscientist and sleep expert Matthew Walker gives us a new understanding of the vital importance of sleep and dreaming. Within the brain, sleep enriches our ability to learn, memorize, and make logical decisions. It recalibrates our emotions, restocks our immune system, fine-tunes our metabolism, and regulates our appetite. Dreaming mollifies painful memories and creates a virtual reality space in which the brain melds past and present knowledge to inspire creativity.
Walker answers important questions about sleep: how do caffeine and alcohol affect sleep? What really happens during REM sleep? Why do our sleep patterns change across a lifetime? How do common sleep aids affect us and can they do long-term damage? Charting cutting-edge scientific breakthroughs, and synthesizing decades of research and clinical practice, Walker explains how we can harness sleep to improve learning, mood, and energy levels; regulate hormones; prevent cancer, Alzheimer’s, and diabetes; slow the effects of aging; increase longevity; enhance the education and lifespan of our children, and boost the efficiency, success, and productivity of our businesses. Clear-eyed, fascinating, and accessible, Why We Sleep is a crucial and illuminating book.

Why We Sleep
Access thebmj. One of the professors at Edinburgh Medical School, where I was taught from , was a world expert on sleep, but I remember hearing little about sleep at medical school. We were taught about sleeping pills, and I remember routinely prescribing them for patients undergoing surgery the next day—with no understanding of the damage I was doing. Generally, like most doctors, I thought little about sleep. His core argument about the public health challenge is that we all need at least seven and preferably eight hours sleep a night because sleep is vital for many functions of the brain and body, including memory, problem solving, attention, immune function, growth, and the effective and efficient functioning of most of our organs. Lack of sleep leads to dementia, raised blood pressure, heart disease, stroke, cancer, road traffic and other injuries, and proneness to infection—in other words to all the commonest causes of morbidity and mortality. Yet many people in the developed world are not getting seven to eight hours sleep a night, and crucially he shows that you cannot catch up on lost sleep—sleeping late at the weekend will not undo the damage done during the week.
