Most of our internal clocks are a little bit slow, and in the absence of consistent light cues — like when you travel across time zones — the pacemaker cells in your body want to have a longer day, said Michelle Girvan, a physicist at the University of Maryland who worked on the model published in the journal Chaos on Tuesday.

马里兰大学的物理学家米歇尔‧葛文(MichelleGirvan)参与了建构这套模型的工作,研究成果周二时在《混沌》(Chaos)期刊上发表。葛文表示,我们体内大部分生物钟都稍微慢些,在没有持续稳定的光源信号时,比如跨时区旅行的时候,体内的节律细胞就会想让一天更长一些。

“This is all because the body’s internal clock has a natural period of slightly longer than 24 hours, which means that it has an easier time traveling west and lengthening the day than traveling east and shortening the day,” Dr. Girvan said.

“这全是因为人体内建时钟的自然周期比24小时稍长一些,也就是说,在向西旅行、导致一天的长度拉长时,感觉会比向东旅行导致一天缩短时更好受一些。”

【经典句式】

internal clock生物钟

lengthen拉长

shorten缩短

Jetlag can be resolved by matching your internal clockto your destination’sclock as soon as possible. (There’s an app for that). So the researchers built a model that considers all of your pacemaker cells, how sensitive you are to light, the brightness of light, multiple time zones and people’s slightly off kilter internal clocks. They hope the model offers a simple way of explaining how a typical body might recover from jet lag with no intervention. That is, how its pacemaker cells try to synchronize in the presence of different light cues (like sunshine, artificial light or dim light from clouds) when arriving at various time zones three hours, six hours, nine hours and 12 hours away either to the east or west.

要解决时差问题,你可以让生物钟尽快调整到与目的地的时间同步(有个手机应用可以帮忙)。所以研究人员建立了一个模型,将你的节律细胞、你对光线的敏感度、光线强度、跨越时区的多寡,以及我们稍稍失准的体内时钟全都纳入考虑。他们希望这个模型可以提供一个简洁的方式,来解释正常人的身体如何在没有外在干预的情况下,把时差倒回来。也就是说,我们在抵达与出发地相差3小时、6小时、9小时、12小时的目的地之后,不论旅程是向东或向西,身体节律细胞是如何根据新地点不同的光线信号(比如阳光、人造光,或云层筛落的黯淡光线)进行同步的。

The model confirms what was already known: Generally, westward recovery is easier than eastward. But it also helps us understand that flying across more time zones can sometimes beeasier than traveling across fewer.

这个模型证实了我们已知的事实:一般来说,向西飞行导致的时差会比向东飞行的时差更容易克服。但它也让我们了解到,有时跨度大的时差反而会比差距较小的时差更容易适应。

【经典句式】

confirm证实

recovery恢复
