Know Your Triggers

Be aware that you may have more than 1 trigger, and that some triggers may work together. Common migraine triggers include:

  • Food and nutrition. Skipping meals or not drinking enough water can trigger headaches. So can certain foods, such as caffeine, monosodium glutamate (MSG), aged cheese, or sausage.

  • Alcohol. Red wine and other alcoholic beverages are common migraine triggers.

  • Chemicals. Scents, cleaning products, gasoline, glue, perfume, and paint can be triggers. So can tobacco smoke, including secondhand smoke.

  • Emotions. Stress can trigger headaches or make them worse once they begin.

  • Sleep disruption. Staying up late, sleeping late, and traveling across time zones can disrupt your sleep cycle, triggering headaches.

  • Hormones. Many women notice that migraines tend to occur at a certain point in their menstrual cycle. Birth control pills or hormone replacement therapy may also trigger migraines.

  • Environment and weather. Air travel, changes in altitude, air pressure changes, hot sun, or bright or flashing lights can be triggers.

Control Your Triggers

These are some of the things you can do to try to control triggers:

  • Avoid triggers if you can. For example, stay clear of alcohol and foods that trigger your headaches. Use unscented household products. Keep regular sleep habits. Manage stress to help control emotional triggers.

  • Change your behavior at times when triggers can't be avoided. For example, make sure to get enough rest and drink plenty of water while you're traveling. Make sure to carry a hat, sunglasses, and your medications. Be alert for migraine symptoms so you can treat a migraine early if it happens.
