Matthew Walker is a professor of neuroscience and psychology at UC Berkeley, the Director of its Sleep and Neuroimaging Lab, and a former professor of psychiatry at Harvard University. He has published over 100 scientific studies and has appeared on 60 Minutes, Nova, BBC News, and NPR’s Science Friday. Why We Sleep is his first book.
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
总之,鼓吹每天睡三小时看四点钟的洛杉矶,是现代人类最愚蠢的观念之一。普通的说,这本书讲的很多新研究结论很有意思,比如晚上喝酒、吃褪黑素对睡眠其实危害巨大。但是我更看重作者的私货:“既然演化让几乎所有动物都具有睡眠这种近乎自杀性的行为,那么一定有什么重要得要命的理由。”作者对这个理由的猜测是我见过的最接近准确的答案:nREM睡眠是腾空临时记忆空间,而REM睡眠是将这些存储转移到永久存储中;而梦的作用是让人对一段记忆安全地去除感情。
评分非常有用也比较有意思的一本书,向所有读者群推荐(NY Times Bestseller)。书以一个问题开始:我们(虫鱼鸟兽一切动物)为什么要睡觉?为什么生物经过这么漫长的进化,还一直保留着睡觉这个看起来会极大降低存活率(比如睡着了很容易被偷袭)的机制?水里需要不停游动的鱼类,或者需要跨洋级别长期飞行的鸟类都各自进化出了一些像一次只睡半边脑之类的 workaround 也无法完全避开睡觉,究竟是为什么? 当然书并没有给出答案的完整刻画,因为完整的刻画应该还是生物研究中的谜题之一,但是书给出了一个很重要的定性答案:睡觉并不(仅仅)是一种休息(比如,像电脑休眠那样,机能停止运行),而是一种 ……(字数限制,见长书评吧。。。)
评分作为一个以研究睡眠为生的人,我最开始觉得,写睡眠的科普书对我还有什么新意?故而虽然早在一年前就听过作者的新鲜空气访谈,还是没有找来看。但真正听完了全书,却意外地发现自己学到很多新东西,也许是因为背景知识储备比较充分,所以新东西容易吸收,但同时确实也是因为作者写得清楚有条理,而且在很多地方,尤其是睡眠在进化中的作用、以及睡眠的神经机制方面有很多独到见解。总之非常推荐。
评分也许并不是动物进化出了睡觉这件事,而是动物最原始的状态就是睡眠状态,进化让动物能周期性地“醒过来”If sleep does not serve an absolutely vital function, then it is the biggest mistake the evolutionary process has ever made. Wake: reception,NREM: reflection (storing&strengthening raw ingredients), REM: integration (interconnecting,building a more accurate model, innovative insights&problem-solving
