Oh, the power of a good night’s sleep. A whole gamut of positive benefits can be seen from getting enough rest, but for many of us, hitting the sack can be challenging. There’s plenty of advice out there about what to do to get to sleep but what about what not to do? Click through for some of the pre-bedtime activities that could be hurting your chance at getting a good night’s sleep。啊，伟大的睡眠！良好的睡眠能带来极大的好处，但对我们有些人来说，睡觉也不是件容易事。关于“做这几件事能让你睡得好”的建议铺天盖地，但有人讲过“睡觉前不要做以下几件事”吗？看这里吧。我们来告诉你睡觉前绝对不能做的几件事。
1. Exercise锻炼
No, you don’t get to ditch your yoga mat or running shoes all together. Exercise is a vital activity for your health, and can actually contribute to getting better-quality sleep. The problem, though, is that exercising within three hours of bedtime can raise your body temperature, and make dozing off more difficult. Breaking a sweat, then, is best left for earlier in the day!先别急着把瑜伽垫或跑鞋丢了。锻炼对于健康来将很重要，同时也能帮你获得优质的睡眠。但问题在于，睡前3小时的锻炼能提高你的体温，并让你更加清醒。因此，锻炼这事儿最好放在更早些时候进行。
2. Watch TV/Surf the Web看电视或上网
