Weather changes, especially fluctuating temperatures and humidity, can trigger migraines, and dehydration often plays a key role.
Dehydration reduces blood volume, potentially leading to constricted blood vessels in the brain, which can trigger migraines.
Staying hydrated by drinking plenty of water, consuming hydrating foods, and avoiding sugary drinks can help prevent weather-related migraines.
