Does Exercise Trigger Headache?

运动会引发头痛吗？

Dear A Moment of Science,

亲爱的片刻科学家，

I like to exercise, but I suffer from migraines and worry that getting my sweat on at the gym could trigger a headache. Am I right to be cautious?

我喜欢锻炼身体，但是我患有偏头痛，担心在健身房流汗会引起头痛。我这样顾忌对吗？

Good question.

问得好。

For some people, exercise can in fact lead to a migraine. But most studies have shown that, on average, exercise may actually help ward off migraines. At the very least, exercise doesn’t seem to hurt most migraine sufferers.

对于一些人来说，事实上锻炼的确会引发片头痛。但是大多研究表明，平均来说，锻炼确实可以规避偏头痛。至少，锻炼不会伤害到大多数的偏头痛患者。

Right,one study done in Sweden put more than ninety migraine prone folks into three groups: one that exercised for around forty minutes three times a week, another that was given a drug to prevent migraines, and a third had regular relaxation sessions. After three months, and then an additional six months of follow up, the study found that migraines were reduced for people in all three groups.

是的，一个在瑞典的研究把90个有偏头痛倾向的人分成3组：一组一周三次运动约40分钟，另一组会领到防治偏头痛的药物，第三组进行有规律的放松练习。三个月以后，再继续6个月，研究发现三组的偏头痛患者都减少了。

Another, smaller study examined more than twenty-five migraine sufferers before, during, and after working out on stationary bikes. After three months, the subjects all experienced fewer headaches.

还有一个比较小型的研究，之前25以上的偏头痛患者，三个月后，在户外骑健身车过程中和以后，被研究者头痛的情况减少了。

So at least according to these studies, exercise appears to be a viable alternative to migraine drugs. To be clear, though, this doesn’t mean that working out never triggers migraines.

因此至少按照这些研究，锻炼身体可以看成是另外一种治疗偏头痛的药物。更清楚地说，尽管这不意味着锻炼身体了就不会头痛了。

Especially if you don’t exercise regularly, it’s probably best to ease into it and see how your head reacts. If working up a sweat doesn’t appear to trigger a headache, then you can gradually build up to higher intensity workouts.

特别是如果你没有有规律锻炼，这可能是最好的逐步适应的方式，再看看你的头是什么反应。如果流汗没有引发头痛，那么你能逐步开始强度更大的锻炼。
