What are some triggers for migraines?

There are many types of triggers for migraines. They are often hard to study because not everyone has the same triggers and people can have many different types of triggers. Some of the common triggers include things like alcohol, wine, aged cheese, stress, or what we call stress letdown, when the stressful event is over. Poor sleep, skipping or delaying a meal can be a trigger. In women, hormonal changes or menstrual cycles can be a trigger as well.
