Someone who can't sleep is called an insomniac.

无法睡着的人被称为失眠症。

An insomniac is someone who can't sleep easily.

失眠症是指无法轻易入睡的人。

Really tired insomniacs who can't focus get up at 4 a.m. too.

凌晨4点起床的也是真的很累的失眠症。

So does this chatty insomniac have a name?

哦 那这个健谈的失眠症叫什么啊？

If you're an insomniac – someone who can't sleep easily – it's tempting to open up your laptop and start shopping.

如果你是失眠症——一个很难入睡的人——那么打开你的笔记本电脑开始购物是很有诱惑力的。

While that happens to everyone every once in awhile, people with insomnia have to deal with these symptoms night after night.

个人都有过这样的一段时间，而有失眠症的需要一晚一晚地抵抗这些症状。

So, I think it will really lead to a complete redefinition of the diagnosis of people who have idiopathic hypersomnia or insomnia.

因此，我认为这将真正导致对特发性嗜睡症或失眠症的诊断进行彻底的重新定义。

Another condition is called fatal familial insomnia, where patients have symptoms such as progressive insomnia, weight loss, extreme body temperatures, and rapidly progressing dementia.

Blocko：另一种情况称为致死性家族性失眠症，会出现进行性失眠、体重减轻、体温过高和快速进展性痴呆等症状。

And the evidence is in the professional literature, in books and journal papers, etc. And if you're an insomniac, you're welcome to look at all that.

证据在专业文献 书籍和期刊论文中 等等 如果你是失眠症 你以看看这些。

While most insomniacs somehow manage to drag themselves through the day and function at acceptable, although not optimal levels, --- this is not so for people who suffer from hypersomnia.

虽然大多数失眠症设法以某种方式勉强自己度过一天并在接受的水平上工作，尽管不是最佳水平，但对于有嗜睡症的人来说并非如此。
