We all know sleep matters for job performance. After a week of vacation, you may find your work better than ever. It wouldn't surprise anyone that sleep affects attention, memory and cognition — important factors in the workplace. But striking new research suggests the effect of additional sleep has a high monetary value.

我们都知道睡眠能影响工作表现。外出度假一周，你可能就会发现自己的工作相比从前有所起色。如果说睡眠能影响工作中一些重要元素，如注意力、记忆力和认知水平，没有人会感到谅异。但是一项惊人的新研究表明：多睡觉能带来巨大的货币价值。

A paper — from Matthew Gibson of Williams College and Jeffrey Shrader of the University of California at San Diego, based on data from Jawbone, the fitness- and sleep-tracker company — says that additional time sleeping can translate into thousands of dollars in wages.

威廉姆斯学院的马修·吉普森和加州大学圣迭戈分校的杰弗里·施雷德根据健身和睡眠跟踪公司Jawbone的数据作了一篇论文，认为多出的睡眠时间可以转化成数千美元的薪资。

In fact, they calculate that a one-hour increase in weekly sleep raises wages by about half as much as an additional year of education.

事实上，根据他们的计算，每周多睡1小时增加的工资，相当于多上1年学涨薪水平的1/2。

Now, the story is not so simple. Don't think you can start to sleep more and you will instantly make more money. It's more about the subtle interplay between how people schedule their lives, how much time they have available to sleep and how that affects worker performance and, ultimately, earnings.

呃……事情其实没那么简单。不要以为你可以开始多睡觉，然后就能立刻赚到更多钱。这里面还有一些微妙的互动调整，关乎人们如何计划他们的生活、他们有多少时间可以用来睡觉、睡眠如何影响工作表现，还有最后如何影响到薪水。

They find that a one-hour increase in average weekly sleep in a location increases wages by 1.3 percent in the short run, which include changes of less than a year, and 5 percent in the long run. By moving to a location where a sunset is one hour earlier, a worker will make an additional $1,570 a year.

他们发现，在一个固定地区，每周平均多睡1小时，薪水短期（1年内）会涨1.3%，长期会涨5%。而如果搬到一个日落早1小时的地区，每人每年可多赚1570美元。

Not all of these wage differences are due directly to sleep, the researchers caution. Some could be due to the cumulative influence of other people. If the workers around you are made slightly more productive by sleeping better, that could make your work more productive, too.

研究人员提醒说，并非所有的薪资水平差异都与睡眠直接相关，其中一部分可能源于其他人带来的总体影响。如果你周围的人能因为睡得更好而变得更有效率一点，你也会变得更有效率。
