Headache Triggers

The most common trigger of headaches is stress. Studies have found that it is the day-to-day stresses, not major life changes (such as moving, getting married, or having a baby), that are most often linked to headaches. Foods can also be a headache trigger. Some scientists believe that certain foods contain chemicals that can constrict the arteries and initiate a migraine, or that some foods can cause headaches by setting off an allergic reaction. Other common headache triggers can include strong odors, a lack of food, and dehydration.
