Weather Conditions & Migraine Attacks

Meta-analysis of 31 studies

Journal of Neurology - April 2025

Li S, Liu Q, Ma M, Fang J, He L

Key Research Findings:

⟲

Weather Changes

Significant trigger factor for migraine attacks (RD = 0.47)

°F

Temperature

Associated with migraine attacks (OR = 1.15)

hPa

Ambient Pressure

Associated with migraine attacks (OR = 1.07)

Air Pollutants Associated with Migraine Attacks

PM10

OR = 1.07

CO

OR = 1.08

PM2.5

OR = 1.04

O3

OR = 1.12

NO2

OR = 1.08

SO2

OR = 1.02*

*Not statistically significant

Conclusion

This meta-analysis found that weather conditions, especially temperature and ambient pressure changes as well as increased levels of certain air pollutants (PM10, PM2.5, NO2, CO, and O3), are significantly associated with triggering migraine attacks.

What This Means For Migraine Patients

Weather Forecasting

Consider using weather forecasting apps that specifically track migraine triggers. Being prepared for upcoming weather changes could help you take preventive measures before an attack occurs.

Air Quality Monitoring

Air pollutants such as PM10, PM2.5, NO2, CO, and O3 are linked to increased migraine attacks. Consider monitoring local air quality indexes and limiting outdoor activities on high-pollution days.

Temperature Control

Sudden temperature changes can trigger migraine attacks. Maintain consistent indoor temperatures and dress appropriately when heading outdoors during extreme weather conditions.

Pressure Changes

Barometric pressure changes may trigger migraine attacks. Consider tracking your symptoms alongside pressure changes to identify your personal threshold and prepare accordingly.
