That suggests that catch-up sleep may undo some but not all of the damage that sleep deprivation causes, which is encouraging, given how many adults don't get the hours they need each night.

这表明补觉可以弥补部分但不是全部睡眠缺乏造成的损害，考虑到有很多成年人每晚都没有得到他们所需的睡眠时间，这令人鼓舞。

It takes different forms: some people can get to sleep on time, but wake up much too early; others get a full night's sleep but still feel exhausted when they wake up.

失眠症有不同的形式：有些人可以准时睡着，但是形来太早；其他人睡了整个晚上，但醒来时仍旧觉得筋疲力尽。

I never understood why some people would work late into the night and sleep most of their mornings away, but now that I am sitting here, at 1am, listening to the same song on repeat, I get it.

我一直不理解为什么有些人晚上会工作到很晚，然后将早上的大部分时间用来睡觉，但是现在，已经凌晨1点了，我坐在这里，反反复复听着同一首歌，终于明白了。
