Does Weather Affect Your Joints?: The Cold’s Impact on Pain

As we enter the heart of the winter months, many people may start to notice and increase in stiff and achy joints. Joint discomfort is common in colder temperatures, especially for those who already live with musculoskeletal (MSK) conditions such as arthritis or previous, unrecovered injuries.

Although studies have not yet found definitive answer, many patients report changes in the weather does have an effect on their joint pain.

But what is it about cold weather that seems to cause us trouble?

Below are some possible causes of joint pain and stiffness:

1. Joint Fluid Gets Thicker — and Joints Get Stiffer

Your joints are cushioned and lubricated by synovial fluid. When the temperature drops, this fluid can become more viscous, meaning it does not cushion or lubricate our joints as well. This results in joints feeling stiffer, especially first thing in the morning or after sitting still for a while.

For people with arthritis, where the joint surfaces may already be roughened or inflamed, this thickening can make an already tricky movement feel even tighter.

2. Muscles Tighten in the Cold

Your muscles naturally contract more in cold weather as your body works to conserve heat. This extra tension can reduce the flexibility around your joints and increase the sensation of discomfort.

If you have existing MSK conditions, for example a long-standing back issue or previous knee injury, your muscles may already be doing more work than usual to support the area. Add cold-induced tension on top of this, and your joints can feel even more pressured.

3. Reduced Blood Flow

When you are cold, your body directs blood away from your extremities (like hands, feet, and knees) to protect your core temperature. Decreased blood flow means less warmth and slower oxygen delivery to the tissues that support your joints. This can make tendons and ligaments feel tight and less responsive.

People with Raynaud’s phenomenon, autoimmune conditions, or chronic soft-tissue problems often feel this most intensely.

4. Atmospheric Pressure Drops

Drops in barometric pressure, which are common before cold, wet weather, may allow tissues in the joint to expand slightly. For joints that are already inflamed or arthritic, even tiny changes can irritate surrounding nerves and increase pain sensitivity.

5. Reduced Activity in Winter

Cold weather often leads to reduced activity. We curl up indoors, skip the walks, and generally move less. But movement is one of the best ways to lubricate your joints, maintain muscle strength, and keep tissues healthy.

When activity drops, stiffness increases.

What Can You Do to Help Your Joints in Cold Weather?

• Warm up gradually every morning - Gentle mobility exercise, such as seated marching or cat-cows, can work wonders.

• Dress in layers to keep joints warm, especially knees and hands.

• Stay active, even if it is indoor stretching or walking breaks from your desk.

• Heat therapy (heat packs, warm baths) can ease stiffness.

• Strength training helps support and protect your joints—especially in winter.

Cold weather may not cause MSK conditions, but it can definitely amplify them. Understanding why your joints act up in winter can help you plan ahead and keep you comfortable.

With the right habits, winter joint pain does not have to be something you simply live with. This habits can help you reduce stiffness and manage pain through the winter months.
