Heat, Weather Changes Increase Migraine Risks Among Older Adults

Migraine headaches affect approximately 10% of older adults, with heat and humidity being significant triggers. A study from the American Headache Society found that every 10-degree increase in temperature correlates with a 6% increase in migraine frequency. Weather changes, such as falling barometric pressure from approaching low-pressure systems, also contribute to migraine onset, possibly due to physiological sensors in the nose, sinuses, or inner ear detecting these changes.

Lightning has been linked to a 30% increase in migraine frequency, likely due to changes in air chemical composition. Older adults face heightened health risks during extreme heat due to reduced ability to regulate body temperature, compounded by chronic illnesses and medications that affect hydration and perspiration. For instance, diuretics and some antidepressants can impair the body's cooling mechanisms and increase dehydration risk.

To mitigate summer-related migraine triggers, staying hydrated with water and electrolytes is essential, alongside avoiding bright sunlight—especially for those sensitive to light—and limiting exposure to poor air quality, which has been linked to increased emergency visits for migraine sufferers. Over-the-counter pain relievers can help manage symptoms, but frequent migraines may require preventive medication prescribed by a physician. These insights highlight the intersection of environmental factors, aging physiology, and migraine management, underscoring the importance of tailored healthcare strategies for older populations during warmer months.
