What's that orange thing on your computer screen?
你电脑屏幕上那个橙色的东西是什么?
It's something I bought yesterday. It's plastic sheet that blocks blue light. I have one that I use to cover my phone screen too.
这是我昨天买的东西。这是一块能阻挡蓝光的塑料片。我还有一块用来遮盖手机屏幕。
What do you mean by blue light?
你说的蓝光是什么意思?
Blue light includes natural light, but it also includes light that isn't natural, for example, from computers, phones, televisions, and other electronic devices.
蓝光包括自然光，但也包括非自然光，例如来自电脑、电话、电视和其他电子设备的光。
So blue light is harmful, and that's why you want to block it?
蓝光是有害光，这就是你要阻挡它的原因吗？
It isn't that simple. Blue light isn't necessarily bad for us.
没那么简单。蓝光不一定对我们有害。
In fact, we need blue light during the day to be healthy, but too much blue light, especially from electronic devices, can harm our health by weakening our vision and making it harder for us to fall asleep.
事实上，我们白天需要蓝光来保持健康，但过多的蓝光，尤其是来自电子设备的蓝光，会削弱我们的视力，使我们入睡变得困难，从而损害我们的健康。
And poor sleep can cause all sorts of health problems.
而且睡眠不好会导致各种健康问题。
I'm not so sure that sleep is nearly as important as people always say it is.
我不确定睡眠是否像人们常说的那样重要。
I haven't slept enough in months because I have too much work to do.
我已经几个月没睡饱了，因为我有太多的工作要做。
And I feel fine. It's the same for most of my friends.
我感觉还好。我的大多数朋友都是这样。
Poor sleep might be a problem for older people, but surely young people can handle late nights.
睡眠不好可能是老年人的问题，但年轻人肯定应付得了熬大夜。
Well, the research I've read shows that sleep is probably even more important than we thought.
我读过的研究表明，睡眠可能比我们想象的还要重要。
And that not having enough sleep can contribute to serious health problems like obesity and heart disease.
睡眠不足会导致严重的健康问题，如肥胖和心脏病。
And all the artificial blue light from electronic devices means we have to try harder to sleep well.
电子设备发出的人造蓝光意味着我们必须更加努力地睡个好觉。
Maybe you're right. I'm on my computer very late most nights and that's probably why I don't sleep enough.
也许你是对的。大多数晚上，我都在电脑前待到很晚，这可能就是我睡眠不足的原因。
