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.《睡眠之谜》于2020年美国上映，由Terri,Randall导演，杰伊·桑德斯等主演的一部记录片！星辰影院提供《睡眠之谜》免费在线观看，《睡眠之谜》完整未删减版在线观看。星辰影院所有迅雷下载资源以及在线观看资源由云端程序自动抓取，如果你喜欢《睡眠之谜》最新一期，欢迎分《睡眠之谜》给你的好友，本片只做交流学习，请勿用于商业利益行为，请支持《睡眠之谜》正版影片！请下载观看后24小时内删除，感谢支持！
