关于睡眠的10大误解和迷思

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 Part of the problem is we have outdated information and beliefs about this all-important health need.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。

10. More Sleep Is Better for You
10. 睡得越多越好

There could be such a thing as too much sleep. The amount of sleep we need varies by person and also changes as we age. Harvard researchers found that a lot of sleep (9 hours or more) is linked with poor sleep quality. So don’t aim for more sleep—even on the weekends. Aim for better sleep.
睡太多可能会导致睡眠过度。每个人需要的睡眠时间都不一样，且会随着年龄增长而变化。哈佛大学研究员发现，睡得过多（9个小时以上）和睡眠质量差有关。所以不要以睡得更久为目标——即便是在周末，而是要力图提升睡眠质量。
