即使是少量运动,也能带来幸福感

但那些研究关注的是锻炼和抑郁或焦虑这些心理问题之间的关系。以往的研究很少探索身体活动和乐观情绪之间的联系，尤其是对那些心理本来就健康的人。而且以往那些研究通常只看单一年龄组或某一运动类型。

On their own, they do not tell us much about the amounts or types of exercise that might best lift our moods, or whether most of us might expect to find greater happiness with regular exercise or only certain groups of people.

单一地看，它们并不能告诉我们，多少运动量或哪些运动类型最能帮助我们提高情绪，抑或是否大多数人都可以通过经常性的锻炼来得到更大的幸福感，还是只有某一类人可以。

So for the new review, in The Journal of Happiness Studies, researchers at the University of Michigan decided to aggregate and analyze multiple past studies of working out and happiness.

因此，在《幸福研究期刊》(Journal of Happiness Studies)上的这篇新综述里，密歇根大学(University of Michigan)的研究人员决定汇总并分析过去多个关于锻炼和幸福的研究。

They began by combing research databases for relevant studies and wound up with 23 published since 1980. Most of those were observational, meaning that the scientists simply looked at a group of people, asking them how much they worked out and how happy they were. A few of the studies were experiments in which people started exercising and researchers measured their happiness before and after.
