The scientists say that circadian clocks play an important part in healing.

科学家指出，昼夜节律在治疗方面有着重要的作用。

Everyone has something called an internal or circadian clock which tells you when your body is ready to do different things.

每个人都有体内生物钟，它会告诉身体何时做什么事。

Participants reading the iPad took about 10 minutes longer to fall asleep, secreted less sleep-inducing melatonin, and shifted their internal circadian clock.

而平板组要花大约10多分钟才能入睡，睡眠中分泌的褪黑激素也比较少，而且自身内在的生物钟也受到影响。

Let's take, for example, the circadian clock.

让我们以生物钟为例。

This is the first time that the circadian clock within individual cells has been shown to determine how effectively they respond to injuries, he said.

他说，“这项研究首次显示出，个体细胞内的昼夜节律能够对伤口作出有效反映”。

" If you catch up during weekends, you habitually eat later, because the circadian clock is shifting, " Polotsky said. " Add in after-dinner snacks; the sleep-deprived eat much more after dinner, as well."

“如果你在周末补觉，你通常会更晚进食，因为生物钟往后推了。还有饭后零食，缺觉者在饭后吃的零食会多得多。”

One of Kleitman's best-known experiments involved spending 32 days in a dark cave as he worked to shed light on the limits of the body's inbuilt circadian clock.

Kleitman 最著名的实验之一是在黑暗的洞穴中度过 32 天，努力揭示人体内置生物钟的极限。

Pretty much all the cells in the body have little circadian clocks and they help kind of optimise our function, so lack of sleep can throw those out, and it can definitely affect your immune response.

体内几乎所有细胞都没有生物钟， 它们有助于优化我们的功能，因此睡眠不足会导致这些细胞消失，并且肯定会影响您的免疫反应。
