翻译人员: Zhouli Chen 校对人员: Zizhuo Liang

你知道有一个全球性的实验

on approximately 1.6 billion people

在75个国家里大约16亿人中

across 75 countries twice a year?

每两年实行一次吗？

It’s called daylight saving time.

它被称为夏令时

[Sleeping with Science]

[与科学共眠]

The sleep-associated consequences are more significant than you may realize.

与睡眠相关的影响 可能比你想象地更重要。

For example in the spring,

比如说在春天，

when we lose one hour of sleep,

当我们缺失一小时的睡眠时间时，

there is a subsequent 24 percent relative increase in heart attacks.

我们患上心脏病的几率 会增加百分之24。

In contrast, in the fall --

反之，在秋天--

in the autumn,

也就是秋季，

when we gain an hour of sleep,

当我们可以多一小时睡眠时间时，

there is a 21 percent reduction in heart attacks.

我们患上心脏病的 概率会降低百分之21。

Isn’t that incredible?

这是不是难以置信？

And I should also note

我还想说的是

that we see similar changes in things such as road traffic accidents,

在道路交通事故等方面 我们也看到了类似的变化

strokes

不幸的是中风

and, tragically, suicide rates as well.

还有自杀率也是如此。

In fact, even the economy suffers

事实上，即使是经济 也会受到影响

with certain stock market returns taking a downswing

因为在夏时制转变后，

following the shift to daylight saving time

某些股票市场的回报率会下降

and that one hour of lost sleep.

与之下降的 还有那一小时睡眠时间。

This is how fragile our brains,

当谈到睡眠缺失时

our bodies

我们的大脑和身体

and even our societies are

就是这样的脆弱

when it comes to sleep loss.

即使是社会也是如此

But said more positively,

但是我们可以乐观地看待这件事

even just small increases in sleep

即使只是增加一点点睡眠时间

can have immediate as well as long-term health benefits.

我们也可以立即享受到 对健康的长效益处。

So rather than thinking of sleep as a cost,

所以还是不要把睡眠 想成是浪费时间

we can instead think of sleep

我们应该认为睡眠

as one of the very best investments we can make.

是我们最值得的投资
