You’d think the human race would have sleep down to a science by now, but many of us are still sleeping poorly (and so we need top 10 guides to getting better sleep). Part of the problem is we have outdated information and beliefs about this all-important health need. Let’s set the facts straight. Here are 10 things you might have been told about sleep but aren’t completely true.
你觉得人类已经对睡眠了解得很透彻了，但是仍然有很多人睡不好觉（所以我们需要睡眠十大指南）。一部分问题是，睡眠对我们的健康如此重要，但我们掌握的信息和对它的了解已经过时了。来，让我们把事实弄清楚。下面列举了你可能听说过的有关睡眠的十件事，这些都不是完全正确的。
