Question: Why do my joints seem to ache more in the cold or wet?
Answer: A review of recent studies suggests that there is indeed an association between atmospheric pressure and osteoarthritic (joint ‘wear and tear’) pain. However, the evidence for a link between temperature and osteoarthritic pain is less clear. Confusingly, some studies have found increased atmospheric pressure associated with increased joint pain, while others have found people report more pain with decreased atmospheric pressure. We do know that the experience of pain is individual and complex, being influenced by psychological stress, duration of pain, health history and many other variables. It may be that decreasing atmospheric pressure (often when a storm is approaching) could allow the joint capsule (fibrous wrapping) to expand, leading to increased swelling inside the joint. Decreased temperature inside a joint may cause synovial fluid (the joint lubricant) to become more viscous and less effective. For pain with reduced atmospheric pressure, try a compressive joint wrap, but not at night – you don’t want deep vein thrombosis. Or hydrotherapy (water exercise) which can provide relief through water pressure, warmth and buoyancy.
If lower temperatures cause you to have more joint pain, wear warm clothing, use an electric blanket and try performing gentle exercise before you go outdoors.
