As Jasmine and Chrissy from NIU STEAM discussed on the Sound of Science on WNIJ, many people attribute their migraines to changes in the weather. While doctors are still studying the triggers, causes, and physiology of migraines, they do agree that some weather-related factors can bring on an attack.
Factors such as barometric pressure, humidity, temperature, and storms seem to have a link to headaches that can vary from person to person. As weather patterns move across the globe, changes in air pressure can cause blood vessels within the brain to widen, releasing serotonin which is associated with triggering migraines. High humidity levels can also signal the release of serotonin and dehydrate, which can lead to migraines.
People sensitive to temperature may experience more migraines during certain seasons, although more research is needed to determine the exact connection. Lightning has also been loosely associated with migraine symptoms, with some people experiencing headaches when lightning strikes close by. However, studies have produced mixed results and researchers are using lightning ground-sensors to study the effects of lightning on migraines more precisely.
Overall, while there is still much to learn about the connection between weather and migraines, it is clear that some weather-related factors can contribute to the onset of a migraine.
