具體描述
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.
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

##二十一世紀夢的解析，再見弗洛伊德式idiosyncrasy
評分##反正就是要多睡覺。
評分##二十一世紀夢的解析，再見弗洛伊德式idiosyncrasy
評分##給自己愛睡覺找到瞭理由，發現確實如此
評分##大量關於睡眠的科學研究知識。總而言之一句話：韆萬要睡足覺啊！！！！
評分##非常有用也比較有意思的一本書，嚮所有讀者群推薦（NY Times Bestseller)。書以一個問題開始：我們（蟲魚鳥獸一切動物）為什麼要睡覺？為什麼生物經過這麼漫長的進化，還一直保留著睡覺這個看起來會極大降低存活率（比如睡著瞭很容易被偷襲）的機製？水裏需要不停遊動的魚類，或者需要跨洋級彆長期飛行的鳥類都各自進化齣瞭一些像一次隻睡半邊腦之類的 workaround 也無法完全避開睡覺，究竟是為什麼？ 當然書並沒有給齣答案的完整刻畫，因為完整的刻畫應該還是生物研究中的謎題之一，但是書給齣瞭一個很重要的定性答案：睡覺並不（僅僅）是一種休息（比如，像電腦休眠那樣，機能停止運行），而是一種 ……（字數限製，見長書評吧。。。）
評分##A must-read for everyone! Can’t stress enough how important an 8-hour sleep is!
評分##Rem is important. Deep sleep is important. Regular sleep time is important.
評分總之，鼓吹每天睡三小時看四點鍾的洛杉磯，是現代人類最愚蠢的觀念之一。普通的說，這本書講的很多新研究結論很有意思，比如晚上喝酒、吃褪黑素對睡眠其實危害巨大。但是我更看重作者的私貨：“既然演化讓幾乎所有動物都具有睡眠這種近乎自殺性的行為，那麼一定有什麼重要得要命的理由。”作者對這個理由的猜測是我見過的最接近準確的答案：nREM睡眠是騰空臨時記憶空間，而REM睡眠是將這些存儲轉移到永久存儲中；而夢的作用是讓人對一段記憶安全地去除感情。
