AdvertisementIf you’ve noticed that as the weather has shifted, you’ve been getting more headaches, there might be a relatively simple explanation. For some people, thunderstorms, pressure changes and high humidity can cause a different kind of discomfort – a headache that can feel like a tension headache, sinus headache, or, in more severe cases, even migraines. During a thunderstorm, cold and warm air collide, creating an extreme difference in air pressure. AdvertisementHeadaches occur when the air pressure changes affect the small, confined, air-filled systems in our body such as those in the ears or sinuses. AdvertisementAlmost three-quarters (73%) of frequent headache sufferers cite weather and air pressure changes as one of the main causes of their headaches and migraines, according to a survey by the National Headache Foundation.
