With winter now in full swing, many people are once again noticing minor joint discomfort: stiffer knees, less agile hands, and a stiff neck. But does the cold really affect joint pain, or is it just a cliché?
Dr. Gabriella Santalena, a rheumatology specialist at the Orthopedic Rehabilitation Unit of the San Siro Clinical Institute, sheds light on the situation, explaining what happens to the body when temperatures drop and how to protect ourselves during the coldest months.
With age, cartilage loses elasticity and shock-absorbing ability. Cold temperatures further stiffen cartilage, joints, muscles, and tendons, making movement more painful. This is why people with osteoarthritis often experience worse symptoms in fall and winter: temperature and humidity directly affect cartilage and bones, intensifying pain.
Cold causes muscles to contract, producing heat. If contraction persists, it leads to tension, pain, and reduced function. Muscle stiffness and inflammation increase in winter, even among young people, especially those working outdoors or participating in sports.
Cold strongly worsens fibromyalgia symptoms, increasing widespread muscle pain and stiffness, particularly in the neck, shoulders, knees, and elbows. Muscle stiffness increases joint tension, creating a cycle of worsening pain.
In rheumatoid and psoriatic arthritis, cold is not a direct cause of flare-ups, but many patients feel worse in winter due to reduced physical activity and less light exposure.
Cold constricts blood vessels, causing fingers to turn white, then blue, then red, often with pain and possible fingertip ulcers. It is common in autoimmune diseases, but can also appear in healthy people (primary Raynaud’s). Even stress or sudden temperature changes can trigger it.
How to protect yourself:
• Dress warmly and keep the body dry, especially the neck
• Exercise regularly with gentle activities (walking, stretching)
• Use heat therapies (hot baths, mud therapy, massages)
• Keep hands and feet warm; avoid sudden, intense heat on frozen skin
• Severe cases may require vasodilator treatments in winter
If pain is severe, persistent, or limits daily activities. Raynaud’s phenomenon should always be evaluated to rule out autoimmune diseases.
