Why is it that some people get headaches when the weather changes?
I've heard that some people get headaches, others get queasy -- the reason, I hear, is always "pressure changes" but what does that mean?

Yes, it's true, and the reason is that atmospheric pressure changes can impact the small air spaces in the head - the sinuses, the eyes, and the ears. If there's an imbalance in the air-filled spaces it can cause pain and pressure intensity causing headaches. It can result in constriction of blood vessels and can cause a lack of oxygen. You can think of it like going into a closed room, how shutting the door forces pressure in the room, may cause curtains to move, may even make a muffled sound of pressure. Why even plastic containers are a good example, how you have to open a corner and squeeze the excess air out. It's all about air filling a cavity, and pressure being applied to that space. Why it happens to some people, don't know, but for some, it can cause regular and chronic issues, even for some, severe pain. I've even seen issues with jaw and teeth pain from the pressure, with an aching pain in the teeth.
