Answer 2

Answer:

If you're prone to getting headaches, you could find that grey skies, high humidity, rising temperatures and storms can all bring on head pain. Pressure changes that cause weather changes are thought to trigger chemical and electrical changes in the brain. This irritates nerves, leading to a headache.
