Weather Triggers Migraine Headaches

June 21, 2012 -- Weather triggers migraine headaches, especially mild ones, a new study shows. Sixty-six people with a history of migraine headaches kept a diary of their triggers for one year. Of these, slightly more than half reported that they had a sensitivity to temperature change. Researchers found that temperature change was actually the culprit about a fifth of the time, and this association was more obvious on cold days than warm days. "Our study provides evidence of a link between the perception of temperature sensitivity and headache incidence in migraine patients," study author Shuu-Jiun Wang, MD, of Taipei Veterans Hospital in Taiwan, says in a news release. Weather more commonly triggered mild headaches than moderate to severe migraines, the study shows. The findings are to be presented at the 54th Annual Scientific Sessions of the American Headache Society in Los Angeles.
