The recommended seven to eight hours of sleep can be hard to get. But here’s a good excuse to make sure you catch those extra zzz's: a study shows that healthy adults who don’t get enough sleep gained significantly more weight than did their well-rested counterparts.
每天最佳的睡眠时间是7~8小时，但人们却很难做得到。不过，这条新闻大概足以让你找到补觉的动力：一项研究显示，和休息得更好的同龄人相比，睡眠不足的健康成年人更容易长胖。
The research features 225 non-obese subjects in a controlled lab setting. Some were on a restricted sleep schedule, in bed only between the hours of 4 a.m. and 8 a.m. Others had from 10 p.m. to 8 a.m. to lounge in bed.
研究人员招募了225名非肥胖试验者，在严格控制的实验室环境中进行测试。他们限制了其中一部分人的睡眠时间，这些人只能在凌晨4点到早8点间睡觉；而其他试验者则可以从晚上10点一直睡到次日早上8点。
After just five days, those sleeping only four hours a night had gained, on average, more than two pounds, compared to less than a quarter-pound gained by the rested group. Men gained more than women did. The findings are in the journal Sleep.
仅仅五天后，每天只睡4小时的实验组平均增重了2磅以上，而睡眠充足的一组的只长胖了不到1/4磅，与女性相比，男性长得更多。此项研究发表在《睡眠》（Sleep）杂志上。
Why the weighty consequences? Sleep disruption has been linked to high levels of hormones that make people feel hungrier. And the new study found that people filled the extra time they were awake by filling their stomachs. So one step to slimming down might be to rest up.
不同的睡眠时间为什么会有这么明显的差异呢？这是由于，睡眠紊乱会使人大量分泌导致饥饿感的激素。研究人员这次发现，没睡够的人醒来之后，往往都在用食物填塞自己的胃。所以孩子们，想要减肥，就别再熬夜啦！
