9.Nature:睡不够,记忆力差怎么办?饿着
熬夜刷题饿了,胡吃海喝一顿后接着复习?但是身体很诚实地想睡觉 。事实上,这与人懒惰无关,而是进化的结果 ——饱腹之后睡觉是便于更好地巩固记忆 。
2020 年 12 月 2 日,来自宾夕法尼亚大学医学院的 Amita Sehgal 团队在Nature杂志上发表论文Availability of food determines the need for sleep in memory consolidation,研究发现生物体即使不进食,在饥饿状态下也能形成记忆 。然而一旦吃饱,就得通过睡觉巩固记忆 。换句话说,也就是只要吃了东西就得睡觉,否则记忆力更差 。

10. 熬夜伤身体,最伤肠道...
在人们的固有认知中,睡眠不足更多的是影响神经系统的功能 。2020 年 6 月 4 日,来自哈佛大学医学院的研究团队,在Cell上在线发表了题为Sleep Loss Can Cause Death through Accumulation of Reactive Oxygen Species in the Gut的研究成果 。
该研究在一定程度上刷新了人们的认识 ——睡眠剥夺会通过肠道中活性氧自由基(Reactive Oxygen Species,ROS)的积累来导致死亡 。(「听说昨天修仙又死一个」Cell 重磅研究,睡眠不足致死的机制竟然在于肠道?)

看到上述研究,作为科研民工的小编默默地流下泪水:吃得多记忆力差,睡得少性命不保,太难了!
