A recent study published in *Neurology* reveals a significant link between record heatwaves and an increased risk of migraine headaches. The ten-year study, involving over 7,000 participants, identified air pollution, temperature fluctuations, and humidity as key weather-related triggers. High levels of air pollution were correlated with increased hospital visits for migraines, while exposure to high UV radiation and fluctuating humidity were linked to more frequent migraine occurrences. The article emphasizes the importance of understanding personal migraine triggers, especially as climate change exacerbates these environmental conditions.
