2024考研英语同源外刊:为什么说半夜醒来不要看时间?
If you wake up in the middle of the night, it might be tempting to check the time and see how many more hours you have left before morning. But this is a bad idea.
如果你在半夜醒来，你可能很想查看时间，看看自己还能睡多久。殊不知，这种行为是错误的。
Looking at any source of light, whether a digital clock or phone, sends signals to the brain to wake up and turn off production of the sleep-promoting hormone melatonin.
无论是用手机还是电子表查看时间，我们都会接受到光源的刺激，这可能会向大脑发送讯号，抑制褪黑素的生成，不利于促进睡眠。
Biological clocks help regulate the timing of bodily processes, including circadian rhythms. Circadian rhythms are 24-hour cycles that are part of the body's internal clock, running in the background to carry out essential functions and processes.
“生物钟”调节着人体的睡眠习惯，使之契合昼夜节律。昼夜节律是指生命活动以24小时左右为周期的变动，它是身体内部时钟的一部分，在后台运行，执行基本功能和过程。
One of the most important and well-known circadian rhythms is the sleep-wake cycle. The circadian rhythm and sleep-wake system are sensitive to light, and even a glance can make falling back to sleep more difficult.
人体的“睡眠-觉醒周期”就是昼夜节律的典型表现之一。昼夜节律和睡眠-觉醒周期对光很敏感，哪怕是瞥一眼时间都有可能造成入睡困难。
But even more importantly, checking can create a feeling of urgency causing additional stress. And that's anything but sleep-inducing.
但更重要的是，看时间可能给我们带来紧迫感，从而产生不必要的压力，这会直接影响我们接下来的睡眠活动。
Dr Nerina Ramlakhan, a physiologist, sleep and stress management expert suggests that checking the time every time you wake up will just lead to a more disturbed night.
生理学家、睡眠和压力管理专家内里娜·拉姆拉克汉博士表示，每次半夜醒来都看一下时间只会让你的睡眠更加不安。
Never check the time if you wake during the night - it is completely normal to wake during the night but if you're a sensitive sleeper then checking the time can send you into a whirl of calculations and worry about how much sleep you will or won't be getting.
半夜醒来时不应看时间——半夜醒来是很正常的，但是如果你比较敏感，那么看时间就可能让你掉入计算时间的漩涡，让你一直担心着自己还有多少睡眠时间。
When the stress takes precedence, cortisol levels increase, and the body becomes alert. This process is counterproductive for maintaining drowsiness.
压力感飙升会导致人体皮质醇水平上升，使大脑更加活跃，不利于保持入睡状态。
重难点词汇：
melatonin [ˌmɛləˈtoʊnən] n. 褪黑激素
circadian [sərˈkeɪdiən] adj. 昼夜的
