睡眠之谜电影免费高清在线观看全集。 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.星空影院桃花影院九九影院私人影院樱花影院星辰影院青柠影院神马影院三妹影院牛马影院金牌影院火力少年王藏身之所电视报道记者 连接新闻的女人们怦然心动20岁第四季奔跑吧!小狗第三季追风战警恐怖先生疾风之赛道宝贝公公瞄准儿媳妇的瞬间就湿透了背后的男人一个很默瑞的圣诞节硬汉2:奉陪到底攀登者男儿无罪天网恢恢科琳娜受难遇仙记逆转胜低压槽:欲望之城粤语平凡之路2023保姆俱乐部第二季魁拔之大战元泱界塞雅可疑的服务生奸友继母钟楼怪人1996投入爱情我的老板为何那样D.P:逃兵追缉令第二季直立守护者
