Exploring the role of barometric pressure, the relationship between cold temperatures and joint sensitivity, humidity and the "Winter Blues".
Do you have arthritis at the base of your thumb?
Noticing more pain or stiffness now that the weather’s turned colder? You’re not imagining things, and you’re definitely not alone.
As we move into the winter months, many people with arthritis report a noticeable increase in joint discomfort.
While there’s no single explanation that fits everyone, there are a few scientifically supported reasons why your symptoms might feel worse this time of year. Let’s break them down.
The Role of Barometric Pressure
One of the most common explanations for increased joint pain in winter is barometric pressure. This is the pressure of the air around us that changes with the weather.
Cold air is denser than warm air. This means it weighs more and creates higher atmospheric pressure. When the pressure is high, it presses against your body and may help keep your tissues more compact. But when barometric pressure drops, such as before a cold front, storm, or snowfall, there is less external pressure holding tissues in. This allows tissues around your joints to expand slightly, which may irritate nearby nerves or inflamed areas, especially in already-sensitive joints like the base of the thumb.
Although winter tends to have higher average barometric pressure than summer, it is also when we see more rapid and dramatic fluctuations.
These sudden drops, more common in winter due to passing weather systems, are often when people notice joint pain and stiffness increase. In contrast, summer barometric pressure may be lower overall, but it is usually more stable.
This could explain why some people feel better in the warmer months.
In short, it is not just the cold that affects your joints. It is the changes in pressure, especially the sudden drops, that may be triggering your symptoms.
Cold Temperatures and Joint Sensitivity
The direct relationship between cold weather and arthritis pain is still being studied. Some research suggests a connection, while other studies do not find a clear link. However, many people consistently report feeling worse in the cold, and there are a few reasonable explanations for that.
Lower temperatures can reduce blood flow to the extremities, making joints and muscles feel stiffer and slower to move. Cold can also increase muscle tension, which might aggravate joint pain. On top of that, tissues around arthritic joints may expand and contract with temperature shifts, which can stimulate pain receptors.
Humidity: The Hidden Culprit?
Humidity appears to play a stronger role than temperature alone. Several studies suggest that high humidity, particularly when combined with cold, increases pain and stiffness in people with arthritis. Damp, chilly conditions, such as rainy winter mornings, seem to be especially uncomfortable.
The Winter Blues and Pain Perception
Many people experience seasonal depression during the winter. Depression is known to heighten the brain’s sensitivity to pain. This means your joints may feel worse even if the physical inflammation has not changed. Poor sleep, reduced sunlight, and lower activity levels can all contribute to this effect.
The Good News: You Can Manage This
The seasonal changes will not make your arthritis progress faster, but they can affect how you feel. Fortunately, there are plenty of ways to manage your symptoms:
Apply warmth
Use a heat pack or run your hand under warm water to soothe the joint.
Wear supportive gloves
Thermoskin or compression gloves can provide warmth and gentle pressure, which many people find helpful.
Stay active
Movement keeps your joints lubricated and mobile. Even if the weather tempts you to slow down, sticking to your hand therapy exercises is key. Activity can also improve your mood!
Talk to your hand therapist
They can adjust your exercise program, recommend customised thermoplastic splints, or suggest other strategies to keep you comfortable during colder months.
