打瞌睡能帮助偿还“睡眠债务”吗?

And the answer,unfortunately,is no.Sleep is actually not like the bank.You can’t accumulate a debt and then hope to pay it off at some later point in time.So sleep is an all-or-nothing event in that sense.So you can’t short sleep during the week and then try to binge and oversleep at the weekend.

不幸的是，答案是否定的。睡眠其实和银行不一样。你不能积累债务，然后希望在以后的某个时间点还清。所以在这个意义上睡眠是一件孤注一掷的事。所以你不能在一周内睡眠不足，然后尝试在周末狂欢并在周末睡过头。

So if I were to take a human being and deprive them of sleep for one night,so that they’ve lost eight hours of sleep and then I give them all of the recovery sleep that they want on a second,a third,even a fourth night,they do sleep longer but they never get back that full eight hours that they’ve lost.

如果我剥夺一个人的睡眠,这天晚上,他已经失去了八小时的睡眠,然后我在第二个,第三个,甚至第四个夜晚提供他们想要的所有的睡眠,他们可以睡很长时间,但他们再也找不回失去的睡眠了,整整八个小时,他们已经失去了。

And we can ask then,"Why isn’t there some kind of a credit system in the brain?Why don’t we have a cell that can actually store up that sleep?"

我们可以这样问，“为什么大脑中没有某种信用系统?”为什么我们没有一个能储存这种睡眠的细胞呢?

Because there is precedent for this.We actually have a storage system for calories within in the body and they’re called,"fat cells."Because there was a time during the evolutionary process where we had feast and where we had famine.And when we had feast,we would store that caloric energy and fat cells that when we went into a debt during that caloric famine,we could actually survive.

因为这是有先例的。我们实际上在体内有一个储存卡路里的系统，它们被称为“脂肪细胞”。因为在进化的过程中，我们有过盛宴，也有过饥荒。当我们享用盛宴的时候，我们有能量和脂肪细胞可以储存卡路里，当我们在卡路里饥荒中负债时，我们就能生存下来。

Human beings are the only species that deliberately deprive themselves of sleep for no apparent reason.And that means that Mother Nature has never had to face the challenge of sleep deprivation during the course of evolution and therefore,she’s never had to come up with a safety net mechanism that overcomes a sleep debt.

人类是唯一故意剥夺自己睡眠的物种。这意味着，大自然母亲在进化过程中从来没有遇到过睡眠剥夺的挑战，因此，她从来没有需要建立一个安全的机制来克服睡眠债。
