Cold weather influences the body in multiple ways, causing old bone injuries to hurt more. Be it an old sprain or a major fracture, or simply arthritis– winters make it worse. The interplay of decreased physical activity, alterations in atmospheric pressure, and heightened sensitivity to cold worsen discomfort in injured areas among several other reasons. Here is a lowdown of the same.

Heightened Pain Sensitivity

One key reason injuries tend to feel worse in winter is the impact of cold temperatures on our nerves. As temperatures fall, nerve endings become more sensitive, increasing our vulnerability to pain.This heightened sensitivity can intensify the pain signals transmitted to our brain, making injuries feel more severe than they would in higher temperatures.
In a conversation with the OnlyMyHealth team, Dr Pramod Bhor, Director of Orthopedics and Robotic Joint Replacement Surgeon, Fortis Hospital, Vashi, Navi Mumbai explains that in colder conditions, atmospheric pressure changes affect the fluid in our bodies, particularly around the knees and ankles. A reduction in barometric pressure may also contribute to amplified joint pain for some individuals.
Thicker Synovial Fluid
Cold weather can lead to an increase in the thickness, or viscosity, of synovial fluid within your joints. This fluid acts as a lubricant for joints. When it becomes thicker, the tissues in joints may grind against one another more, resulting in pain.
Decreased Blood Flow and Stiffness
Colder temperatures often cause people to move less or exercise minimally, which can result in a decline in muscle strength and flexibility, leading to soaring joint pain.
Engaging in physical activity can alleviate arthritis pain and enhance functionality, as per a study published in PubMed Central. However, reduced activity, such as when it’s cold and dreary outside, may lead to more discomfort and stiffness.
Increased Inflammation
Inflammation, a typical reaction to injury, may worsen in cold conditions. Cold temperatures cause blood vessels to constrict, potentially trapping inflammatory substances in the affected area and leading to greater discomfort for those with old injuries. A review of previous research indicates that lower temperatures can influence pain sensitivity or tolerance. In specific cases, they might also contribute to nerve inflammation.
The joints most likely to feel pain are the:
- Knees
- Hips
- Spine
- Hands and feet
Increased Inflammation
Inflammation is the body’s natural response to injury, but it can worsen during winter. Cold temperatures cause blood vessels to narrow, which can trap inflammatory substances in the affected areas. This can heighten pain for those with old injuries. In some cases, cold weather can even lead to inflammation of the nerves, further worsening discomfort.

Conclusion
To reduce discomfort, try maintaining an active lifestyle with gentle exercises to improve blood flow and flexibility. Dress warmly to keep your joints protected from the cold, and consult a doctor for persistent or severe pain.
Cold weather significantly impacts old bone injuries and joint pain due to changes in nerve sensitivity, joint lubrication, and blood flow. Understanding these factors and staying active can help alleviate the discomfort and keep your joints healthy during the winter months.
