A recent study published in the journal Neurology suggests that exposure to air pollution could significantly increase migraine activity, with both short-term spikes and long-term exposure contributing to the risk.
Led by researcher Ido Peles from Ben-Gurion University of the Negev, the study tracked over 7,000 individuals suffering from migraines in Be’er Sheva for nearly a decade. The research examined how daily exposure to pollutants—originating from traffic, industrial activity, and dust storms—along with weather conditions, influenced migraine-related hospital and clinic visits.
Findings revealed that days with the highest number of migraine-related medical visits coincided with significantly elevated pollution levels. Notably, coarse particulate matter (PM10) and fine particles (PM2.5) were much higher on these days compared to average levels. Long-term exposure to PM2.5 increased the likelihood of higher migraine medication use by 9%, while elevated nitrogen dioxide (NO₂), commonly linked to vehicle emissions, raised it by 10%.
Conversely, days with lower pollution levels recorded fewer migraine-related visits, reinforcing the connection. The study also highlighted the role of climate: heat and low humidity intensified the impact of NO₂, while cold and humid conditions worsened the effects of PM2.5.
Researchers emphasized that environmental factors act both as triggers and amplifiers of migraine episodes, particularly for individuals already prone to the condition. With climate change expected to increase the frequency of heatwaves, dust storms, and pollution events, experts suggest incorporating environmental risk awareness into migraine management strategies.
Preventive steps such as limiting outdoor exposure during high-risk periods, using air filtration, and timely medication could help individuals better manage symptoms.
