WEATHER

Q: Do changes in barometric pressure affect people? For instance, it sometimes appears to cause headaches in sensitive individuals (like me). I often notice a headache coming on when the weather is changing from a high to low or vice versa, or when it's about to rain. Is this my imagination or what?

Q: Do weather conditions, such as humidity or barometric pressure, effect body parts causing arthritis or other pain?

A: There seems to be no doubt that changes in barometric pressure and humidity along with other weather factors do affect people.

Hippocrates, the great Greek physician of around 400 BC, wrote about weather effects on people. Humidity could have a direct effect on the skin, with the skin expanding slightly with rising humidity and contracting when the air becomes drier. This could explain why humidity changes are painful to people with scar tissue, especially people who have had limbs amputated. Air pressure changes and temperature changes affect people with rheumatoid arthritis. It's easy to imagine how pressure changes could cause headaches, but I don't know exactly how.
