The Expansion Effect

Joints hurt when cold air pressure around your body increases, allowing your body’s tissues to slightly expand.

The Sensitivity Factor

In a healthy joint, this expansion is negligible. However, arthritis and cold weather lead to the expansion of tendons, muscles, and scar tissue, which can put extra pressure on the joint, leading to increased pain.

Synovial Fluid Thickening

Both cold weather and joint pain can make these fluids more viscous (thicker). Essentially, thicker fluid doesn’t flow as easily, which can lead to that morning stiffness.

Nerve Sensitivity
