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

##Rem is important. Deep sleep is important. Regular sleep time is important.

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。

##也許並不是動物進化齣瞭睡覺這件事,而是動物最原始的狀態就是睡眠狀態,進化讓動物能周期性地“醒過來”If sleep does not serve an absolutely vital function, then it is the biggest mistake the evolutionary process has ever made.

##關於睡眠這件事情非常全麵的科普和解析。我覺得印象最深刻的是,作者得齣一個推論,既然我們現代社會的人類,幾乎睡眠不足在城市人口中是常態,那麼也就意味著我們很多人其實一直是在一個sub-optimal的狀態下生活瞭很久,而自己接受瞭自己更低的performance standard,並且還不自知,認為這是正常的。這是一個非常讓人concerning的發現。
