练习双语：睡觉时你的身体正在做这6件事 我们一生当中的三分之一都是在睡眠中度过的。当你睡觉的时候，你大概不知道，你 的身体依旧忙碌得很呢！今天我们就来了解下，你睡着之后身体都在忙些啥呢？ 1. KEEPING TIME 1、生物钟仍在运行 You might be asleep but your hypothalamus is not. Its carefully keeping time for you as part of your circadian rhythm. This not only helps you feel tired so that you go to sleep with the release of melatonin, but a protein called PER is released in the morning that gradually wakes you up, often right before your alarm clock is set to go off. 你也许睡着了，但你的下丘脑并没有睡。它还在一丝不苟地运行着生物钟。下丘脑会分 泌褪黑激素，让你感到困倦，到了早晨，则会释放一种名为PER的蛋白质，让你逐渐苏醒, 通常会在闹钟快响时把你叫醒。 SPOUTING OFF 2、说梦话 What do you have to say when youre asleep? Sleep-talking or somniloquy can range from random noises to complete sentences. About 5 percent of adults do it (its slightly more common in children), and it can happen during any stage of sleep.

This habit, called bruxism, can be caused by emotional or psychological states like stress or anxiety, from an abnormal bite (misalignment of your teeth), or even from sleep apnea. Most people are unaware they do this until their dentist notices evidence of unusual wear. If youre damaging your teeth at night, your dentist can give you a mouth guard to prevent it. 多数人在睡觉的时候都会磨牙，至少总有那么儿次。这种磨牙症可能是由压力或焦虑等 情感或心理状态引发的，也可能是由牙齿不齐导致的，甚至可能和睡眠呼吸暂停有关。在牙 医发现不寻常的磨损痕迹之前，多数人都没有意识到自己磨牙。如果你睡觉的时候磨牙，牙 医可以给你一个口腔防护器来预防损伤。 CLEARING YOUR BRAIN 4、清理大脑垃圾 You think youre resting, but your brain is doing some serious housekeeping every single
