缺乏睡眠成為全球流行病的今天，
我們需要超強睡眠顧問沃克傳授的睡眠全書。
這本書總結數十年來的睡眠研究成果以及最新科學突破，
告訴我們睡眠複雜又迷人的真相。
睡眠與做夢的功能，超乎想像：
．學習之前的睡眠，幫助腦準備形成新記憶；
學習之後的睡眠，可以鞏固記憶、避免遺忘。
．夢提供虛擬實境，讓過去與現在的知識融合，激發創意。
．夢還能撫慰痛苦的記憶，幫助我們走出創傷。
睡眠不足的壞處，不容輕視：
．只要一晚睡四小時，對付癌症的自然殺手細胞數量剩下不到一半。
．腦中的清潔大隊運作不良，無法清除阿茲海默症的毒性蛋白。
．連續清醒十九小時後開車，你的精神狀態和酒駕沒兩樣。
．容易覺得肚子餓，吃飽了卻還想再吃，體重居高不下。
睡眠對專業領域和職場的驚人影響：
．NBA籃球運動員一晚睡眠超過八小時，每分鐘得分會提升近三成。
．NASA發現，短短二十六分鐘的小睡，就能使太空人的表現更好。
．企業中，睡眠不足的員工會缺乏生產力與創意；
管理階層睡得不好，第二天員工的生產力也會降低。
我們的身體健康、心理健康、記憶力、學習力、創意、生產力、
領導力、決策力、智商與情商、吸引力、運動表現，甚至食慾，
這些讓日間生活更精采的能力，
原來都與夜間那場神祕的睡眠有關係。
沃克是傑出的神經科學家，他熱愛睡眠，研究睡眠，
為我們描繪出當前科學對於睡眠的全盤了解，
最後還告訴我們如何睡好覺的訣竅。

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 don't sleep. Compared to the other basic drives in life—eating, drinking, and reproducing—the purpose of sleep remained elusive.

But 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. Among so many other things, 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 immensely accessible, Why We Sleep is the crucial account on sleep that will forever change readers’ minds on the subject.
