Migraine attacks are often brought on by certain triggers. Common triggers include stress, weather changes, some food and beverages, and irregular schedules. Other triggers can include strong emotions, lack of sleep, dehydration, caffeine withdrawal, strong lights, loud noises, heat, humidity, changes in barometric pressure, poor air quality, a menstrual period, and intense exercise, among others. Tracking your triggers with a migraine diary can make it easier for a specialist to help you.
