Climate change may cause migraines, experts say

Experts have found that weather changes can trigger migraines or other types of headaches.

According to experts, this is because weather changes are related to the human body's nervous system, hormonal balance, and blood vessels.

When the weather changes—especially before rain or stormy weather—there is a decrease or increase in air pressure. This causes the arteries around the brain to expand or contract, which can trigger migraines.

In extreme heat or cold, blood flow in the body is affected. Dehydration in hot weather can also aggravate migraines, while high humidity puts a burden on the body's system, especially if you are sweating and dehydrated. For some people, this triggers headaches.

Similarly, in the spring or fall, pollen, dust, or other allergen-causing particles increase in the air. Scientists believe that nasal allergies and inflammation can trigger migraines by affecting the nerve pathways in the brain.

Additionally, bright sunlight, bright lights, or light coming through clouds can also affect the visual sense in some people, triggering an “aura migraine.”

Weather changes also affect sleep-wake patterns, and lack or excess sleep can aggravate migraines.
