The scientific evidence for weather being a trigger factor for migraine attacks is inconclusive. We investigated the association between weather components and the onset and severity of attacks. Headache diaries of 20 migraineurs were analyzed retrospectively and correlated in 4-h intervals to atmospheric air pressure, temperature, and relative air humidity in Berlin (Germany) for a period of 12 consecutive months. Absolute values and relative changes within the preceding 24 h were analyzed. Migraine attacks started most frequently at 4 a.m. and reached the highest intensity between 4 and 8 a.m. A highly significant association between meteorological variables and the occurrence of migraine attacks was found in six patients. The onset of an attack as well as high headache intensity was associated with lower temperature and higher humidity. Our data indicate that a subgroup of migraineurs is highly sensitive to changes of certain weather components.
天气是否是偏头痛发作的触发因素，其科学证据尚无定论。我们研究了天气因素与偏头痛发作的开始和严重程度之间的关系。回顾性分析了 20 名偏头痛患者的头痛日记，并在柏林（德国）连续 12 个月的 4 小时间隔内与大气气压、温度和相对空气湿度相关联。分析了前 24 小时内的绝对值和相对变化。偏头痛发作最常发生在凌晨 4 点，在凌晨 4 点至 8 点之间达到最高强度。在六名患者中发现气象变量与偏头痛发作的发生之间存在高度显著的关联。发作的开始和高头痛强度与较低的温度和较高的湿度有关。我们的数据表明，偏头痛患者中有一个亚组对某些天气因素的变化非常敏感。
