Fuel Memory Loss

加速记忆丧失

You probably know that on the days when you are mosttired, you're forgetful and unfocused -- but sleep deprivation can lead to permanent cognitive issues.

你可能已经感觉到：在特别累的时候，自己总是很健忘、且注意力不集中。但睡眠缺乏能直接带来永久性的认知问题。

The less we sleep, the less we benefit from thememory-storing properties of sleep.

我们睡得越少，我们从睡眠中受益就越少，睡眠则能够帮助记忆恢复。

But additionally, a lack of sleep can cause"brain deterioration," according to a 2013 study, which may at leastin part explain memory loss in seniors.

此外，据一项2013年度的研究显示，睡得太少还会导致“大脑退化”，这个机制至少解释了一些老年人中存在记忆力下降的原因。
