More than half of migraine sufferers are affected by weather. The most common weather factors that affect migraines are:
Major weather changes over one or two days
Changes in barometric pressure
Some migraines attributed to weather are not related to it at all. Many people tend to pin their headaches on weather patterns, when other triggers, such as excessive consumption of caffeine or changes in sleep patterns, may actually be the cause. If weather truly is a trigger for you, watch the forecasts. Then you can take preventive medications when troublesome weather lies ahead. Please consult with your health care provider about the general use of preventive medications for migraine.
