What is the #1 reason cold weather affects joint pain?
- A) The cold air causes muscles to freeze.
- B) A drop in barometric pressure causes tissues to expand.
- C) Lack of Vitamin D makes bones more brittle.
- D) Blood flow increases to the joints to keep them warm.
As barometric pressure drops, it puts less external pressure on the body, allowing sensitive tissues (like those around your joints) to swell. This expansion can irritate the nerves, which is why many people feel like they can "predict the weather" in their knees or back.
