Did you know that there is a global experiment performed

譯者: Lilian Chiu 審譯者: Helen Chang

你可知道，有一項全球性的實驗，

on approximately 1.6 billion people

對象有大約十六億人，

across 75 countries twice a year?

來自七十五個國家， 且實驗一年進行兩次？

It’s called daylight saving time.

這個實驗叫做日光節約時間。

[Sleeping with Science]

〔從科學談睡眠〕

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

它和睡眠相關的後果，

比你所想的還要重大。

For example in the spring,

比如，在春天， 我們少掉一小時的睡眠。

when we lose one hour of sleep,

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

後續心臟病發作的機率 就會相對增加 24%。

In contrast, in the fall --

相對的，在秋天時，

in the autumn,

when we gain an hour of sleep,

我們多了一小時的睡眠，

there is a 21 percent reduction in heart attacks.

心臟病發作的機率就降低 21%。

Isn’t that incredible?

很不可思議，對吧？

And I should also note

我也應該提一下， 類似的改變也出現在

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

比如交通意外事故、

strokes

中風，

and, tragically, suicide rates as well.

還有，很不幸的，自殺率。

In fact, even the economy suffers

事實上，連經濟也受牽連，

with certain stock market returns taking a downswing

某些股票市場報酬會突然向下掉，

following the shift to daylight saving time

且是緊接在轉換到日光節約時間

and that one hour of lost sleep.

以及少了一小時睡眠之後。

This is how fragile our brains,

我們的大腦、我們的身體，

our bodies

甚至我們的社會，就是如此脆弱，

and even our societies are

when it comes to sleep loss.

會受到睡眠喪失的影響。

But said more positively,

但，從正面的角度來看，

even just small increases in sleep

只要稍微增加一點點睡眠，

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

就能產生立即且長期的健康益處。

So rather than thinking of sleep as a cost,

所以，不要把睡眠想成是成本，

we can instead think of sleep

我們可以換個方式，把睡眠想成

as one of the very best investments we can make.

我們能做的最佳投資之一。
