You’ve probably heard someone claim they can predict the weather because their knees start to ache. While it sounds like a myth, there is actual science behind why your joints feel stiff and painful as the seasons change.

As we move through October and the temperature begins to plummet, you might notice that your old injuries or arthritic joints start to flare up. Here is a look at why this happens and what you can do to protect your spine and joints this fall.

The Science of “Weather Pain”

There are two main culprits behind cold-weather aches:

• Barometric Pressure: This is the weight of the air pressing against our bodies. When a cold front moves in, barometric pressure often drops. This decrease in pressure allows the tissues inside your body to expand slightly. If you already have inflammation or arthritis, this subtle expansion takes up valuable space inside the joint capsule, putting painful pressure on your nerves.
• “Sludgy” Synovial Fluid: Your joints are lubricated by something called synovial fluid. Think of it like motor oil in a car. When it gets cold outside, this fluid thickens and becomes less viscous (like cold syrup). This increases friction in your joints, making them feel stiff and creaky.

When to Seek Care

A little extra stiffness on a cold, damp morning is common. However, if the pain is preventing you from completing your daily activities, if a joint is visibly swollen and red, or if the stiffness lasts for several hours, give the clinic a call.
