Keep a daily journal. One way to figure out what might be causing migraines is to keep a journal and record everything from foods eaten to stressful situations. Over time, common triggers could emerge. Avoid triggers. These vary by individual but the best way to fend off a migraine is to be mindful of what sets them off. Once triggers are identified, they can be dealt with or avoided. Yoga. Because stress is often a trigger for migraines, the meditative aspects of yoga could decrease attacks. Studies show that yoga increases serotonin, which relaxes tight blood vessels in the brain. Biofeedback. Biofeedback involves relaxation training aimed at reducing muscle tension in the head and neck. Patients are guided through a series of sessions that teach them to control their breathing, which in turn relieves stress.
