What Causes Migraines?

Weather Changes

Weather changes could worsen the severity of migraine symptoms for some patients, and they may also cause serotonin imbalances that trigger a migraine attack. Triggers related to weather changes can vary considerably for each individual. For example, some patients may find their migraines are triggered by bright sunlight or glare from the sun, and high humidity, dry air, and extreme heat or cold could lead to migraines for others. Barometric pressure changes and windy or stormy weather may also trigger or exacerbate migraines. Since weather changes are beyond our control, they can often be one of the most frustrating migraine triggers for patients. To make it easier to cope, doctors recommend patients keep a headache diary with any weather-related symptom changes, and patients might want to monitor the weather daily. If possible, staying inside during stormy weather and periods of extreme heat or cold is recommended to reduce symptoms.
