具体描述
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

##昨天读了之后 得到了久违的9小时睡眠... demystify了很多问题 比如REM做梦其实是很有用的 像是一种overnight therapy 帮你去重组处理日间的不良情绪；比如喝酒根本无法让你“睡得更好” 只是让你进入了一种麻醉状态而已；比如褪黑素只能帮助你提前召唤来睡觉的时间 具体质量是帮不了的；比如咖啡真的是一种被我们abuse的兴奋剂；比如真的有晨型人和夜型人。我们都会因为各种原因遇到一些sleeping difficulties 但不代表我们有insomnia 减少睡前蓝光的接受 带着好心态 好好睡觉吧
评分##给自己爱睡觉找到了理由，发现确实如此
评分##最主要是两点收获：1、科学的阐述了费洛伊德解析梦那套的误导与错误，有从地方天圆到地圆天方的醍醐灌顶之感，原来做做梦是伴随REM sleep对mental health有各种效果的生理特征，失恋、离婚后的梦并不是简单的日有所思，而是它在帮助我们消化情绪。2、睡眠跟饮食、锻炼一样，并非铁板一块，而是各个阶段的配合，熬夜损失3小时的REM sleep并不是第二天多睡4小时能弥补的，是失去了70%的REM sleep时间，要跟饮食分蔬菜、蛋白、水果、碳水一样认真对待睡眠。sleep deprivation比日常大家防癌的那些细节更致癌以及增加各种慢性病的风险，一直后悔高中沉默网游耽搁学业读完这本书第一次后悔耽搁了自己青春期的宝贵睡眠。从今往后，中午12点后不喝咖啡，晚上10后尽量不看LED。
评分总之，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##大量关于睡眠的科学研究知识。总而言之一句话：千万要睡足觉啊！！！！
评分##二十一世纪梦的解析，再见弗洛伊德式idiosyncrasy
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
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##Rem is important. Deep sleep is important. Regular sleep time is important.
