Jasmine and Chrissy from NIU STEAM discussed the link between weather and migraines on the Sound of Science on WNIJ. Many people attribute their migraine symptoms to changes in the weather, but doctors are still studying the triggers, causes, and physiology of these headaches. Some weather-related factors that seem to be connected to migraines include barometric pressure, humidity, temperature, and storms.
Researchers have found that changes in air pressure can cause blood vessels within the brain to widen, releasing serotonin which can trigger migraines. High humidity levels can also lead to the release of serotonin and dehydration, which can cause headaches. People who are 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 reporting headaches after lightning strikes nearby. Studies have produced mixed results, but researchers are using lightning ground-sensors to study the effects of lightning on migraines more precisely. Overall, while the connection between weather and migraines is still being studied, it is clear that some weather-related factors can contribute to their onset.
