Summary
Many people in the U.S. who have migraines say weather changes can trigger their headaches. Researchers and doctors are still trying to fully understand why this happens, but they know that shifts in air pressure, temperature, and humidity can affect the brain and lead to pain.
Key Facts
- About 39 million Americans experience migraines, with 30% to 50% reporting weather as a trigger.
- Weather changes such as shifts in barometric pressure, temperature extremes, and high humidity can trigger migraines.
- Barometric pressure is the weight of air above us, and drops in pressure, like before a storm, are often linked to migraines.
- Some people might experience migraines due to sensitivity to light and rapid changes in sensory input.
- Air pollutants, bright sunlight, and even lightning can also trigger headaches for some individuals.
- The nervous system in individuals with migraines is more sensitive, making them more affected by environmental changes.
- To manage weather-related migraines, people can track headache patterns and adjust habits like diet and sleep.
- Creating a comfortable home environment on days with extreme weather may help reduce migraine frequency.
