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##睡眠不足的危害微信微博上到处可见。这本书简单来说就是再次重申睡眠不足对于身体，情绪等各方面的负面影响。我觉得比较有意思的是，原来REM做梦的时候，身体应该是处于paralyzed的状态的，大脑好神奇。还有sleep on it是有科学根据的。有的篇幅略冗余。总结下来睡眠很重要，要重视，说起来比做起来容易，要真正做到不简单。
评分##这是一本安利睡觉的书。十四个小时说了一句话：睡得好让你精神好、心情好、学习好、颜值高、胖不了、创意足、挣钱多、省医疗、开车安全、少得癌晚痴呆、死不了。反过来就是说，不好好睡觉会让你变胖、变丑、变学渣、差领导、开车危险、抑郁跑不了、男的蛋蛋变小娘娘化生不了、早痴呆多得癌、老得快、死得早。
评分##实话实说我感觉比较一般，话题是老生常谈了，睡觉很重要，重要到睡不好会导致种种疾病甚至死亡。也可能是我get不到当中的逻辑。前几个月开始听，一直很催眠，到今天终于决定听完。也许催眠就达成了这本书的目的吧。睡前读纸质书和电子书还是有差的，读电子书会抑制身体释放melatonin。不用错觉自己insomnia，being sleep deprived is not insomnia。不过being sleep deprived也没有比insomnia好到哪里去。
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##六颗星！整本书把所有和“睡觉”有关的科学知识非常想尽的写下来，重点是还写得极其有趣。发现好多设计实验的内容和过程也都特别好玩，包括历史上最早研究人类睡眠周期的科学家把自己关在“暗无天日的”山洞里的故事，等等。唯一的小bug是作者为了强调充足睡眠的重要性，举例说切尔诺贝利事件可能是sleep deprivation造成的，有点失偏颇啦。（当然，按照朋友调侃的话说，你懂这么多，依然也睡不好觉呀，这本书并不能真的帮你解决很多失眠问题，但是依然是本很棒的书呀）
评分##介绍了很多比较新的关于睡眠和梦的实验和理论，挺好的。另外也附有很实用的助睡指南，最关键的一条：每天按时睡觉按时起床。
评分##给自己爱睡觉找到了理由，发现确实如此
