Migraine

Several studies have found some migraines are triggered by changes in weather. One study noted that 62% of the subjects in the study thought that weather was a factor, in fact 51% were actually sensitive to weather changes. Among those whose migraines did occur during a change in weather, the subjects often picked a weather change other than the actual weather data recorded. Most likely to trigger a migraine were, in order:

1. Temperature mixed with humidity. High humidity plus high or low temperature was the biggest cause.
2. Significant changes in weather
3. Changes in barometric pressure
