時差N小時:運動會引發(fā)頭痛嗎? Does Exercise Trigger Headache?
親愛的科學(xué)一刻：我喜歡運動，但我患有偏頭痛，擔(dān)心去健身房運動到出汗會引發(fā)頭痛。
Am I right to be cautious?
我應(yīng)該這么謹(jǐn)慎嗎?
Good question.
問得好。
For some people, exercise can in fact lead to amigraine.
對一些人來說，運動其實能導(dǎo)致偏頭痛。
But most studies have shown that, onaverage, exercise may actually help ward off migraines.
但絕大多數(shù)研究顯示，一般而言，運動可能實際上能幫你遠離偏頭痛。
At the very least, exercise doesn't seemto hurt most migraine sufferers.
至少可以肯定，運動并不會對大多數(shù)偏頭痛患者造成損害。
Right,one study done in Sweden put more than ninety migraine prone folks into threegroups:one that exercised for around forty minutes three times a week, another that was givena drug toprevent migraines, and a third had regular relaxation sessions.
正好，瑞典有一項研究將90名患有偏頭痛的人分成3組：一組一周進行3次約40分鐘的運動;另一組服用藥物來防止偏頭痛;第三組則進行定時放松活動。
After three months, and then anadditional six months of follow up, the study found thatmigraines were reduced for people in allthree groups.
3個月后的研究結(jié)果及另外6個月的跟蹤調(diào)查顯示，3組人的偏頭痛都有所緩解。
Another, smaller study examined more than twenty-five migraine sufferers before, during,andafter working out on stationary bikes.
另一項規(guī)模較小的研究對25名偏頭痛患者在健身車上運動前、運動中和運動后的情況進行了調(diào)查。
After three months, the subjects all experienced fewerheadaches.
3個月后，所有的研究對象發(fā)生偏頭痛的次數(shù)都更少了。
So at least according to these studies, exercise appears to be a viable alternative tomigrainedrugs.
因此，至少就這些研究結(jié)論來說，用運動來代替服用偏頭痛藥物似乎是可行的。
To be clear, though, this doesn't mean that working out never triggers migraines.
盡管如此，需要明確的是，這并不意味著鍛煉不會引發(fā)偏頭痛。
Especially if you don't exercise regularly, it's probably best to ease into it and see how yourheadreacts.
尤其當(dāng)你不經(jīng)常運動時，最好是循序漸進地進行運動，并看看你頭部的反應(yīng)。
If working up a sweat doesn't appear to trigger a headache, then you can gradually buildup tohigher intensity workouts.
如果運動到出汗并未引發(fā)頭痛，你就可以逐步進行更大強度的鍛煉。
