内容要义
NOVA: Mysteries of Sleep Like virtually every other animal, humans need sleep to survive. But why? What do we gain from spending nearly a third of our lives in such a defenseless state? And what's at stake if we sleep poorly? The functions of sleep have long been something of a mystery. But now scientists are peering deep into the brain to see what happens while we snooze. One study reveals that well-timed bursts of pink noise can nudge a person's brain waves, extending periods of slow-wave, or deep, sleep. And toddlers learning new words show that taking even a short nap after learning something new can help the information stick. And when it comes to sleeping poorly, it may turn out that having interrupted sleep can be just as harmful as missing sleep altogether. As scientists come to understand the powerful role that sleep -- or lack of it -- plays in everything from memory to trauma to emotion regulation, one thing is clear: This biological function is as crucial as it is complex.

也没啥新进展
感觉还可以，但是这个学科大概进展的还不那么多，感觉收获不是很大。
睡觉，狗命重要，感觉大部分人都没有熬夜基因，多睡基因倒是挺常见
what》播客 和我一起入梦播主 Drew Ackerman 焦虑症引起的睡眠问题
pink noise今晚用起来。slow wave和rem是交替来的，周期约90分钟。睡眠不良的人会在rem期间经历arousal，杏仁核在睡眠后未得到休息（经历紧张事件后应该做转移注意力放松活动再去睡觉）。相对而言，海马体储存短期记忆，在睡眠中转入大脑皮层，午睡有利于提高记忆力和认知水平。microsleep大脑休息几秒，驾驶中0.2秒失去注意力就会导致车祸。不要抵抗“sleep pressure”，消除腺苷酸的最好方法就是好好睡觉。
