During autumn and winter, low temperatures can increase muscle stiffness and joint discomfort, especially in athletes who train outdoors or sustain a high training load. Cold affects the functioning of connective tissue and can hinder its regeneration. How to take care of your joints in the cold months?
Why do joints hurt more when it's cold?
Cold causes vasoconstriction, a reduction in blood flow to muscles and joints. This means that less oxygen and fewer nutrients reach the tissues, which can lead to a feeling of stiffness and less mobility. In addition, low temperatures reduce muscle temperature and synovial fluid—which lubricates the joints— making movement less fluid.
It's not that the cold causes injuries, but it can aggravate minor previous discomfort or delay recovery.
Which areas are most affected in the cold months?
The most exposed joints or those with the highest mechanical load are the ones that notice it the most:
- Knees and ankles, from repeated impact in running or jumping sports.
- Hips, due to muscle tension and loss of mobility.
- Shoulders and elbows, in strength sports or swimming.
The cold acts as an "amplifier" of small overloads that already exist.
How do joints regenerate naturally?
The body repairs connective tissue daily through the synthesis of collagen, a structural protein that needs certain nutrients:
- Amino acids (glycine, proline, lysine), from meat, fish, eggs or legumes.
- Vitamin C, essential for forming collagen, present in citrus fruits, kiwi, pepper or broccoli.
- Minerals such as zinc and copper, which help stabilize the structure, are present in seafood, nuts and whole grains.
A balanced diet is essential for these nutrients to be available and for the body to maintain its ability to repair.
Why does the cold hinder this regeneration process?
Because vasoconstriction reduces the arrival of nutrients and oxygen just when the body needs them most.
With less blood flow, connective tissue repair slows down, and mechanical stress from training can build up.
In addition, the body responds to this situation with a slight local inflammation, a natural reaction to protect the tissues, but if prolonged it can increase stiffness and discomfort.
What role does inflammation play in joint pain during cold?
Inflammation is part of the recovery process: it helps remove waste and repair damaged tissues.
The problem arises when this inflammation remains active for too long, which is common when there is a low temperature, repeated effort or poor recovery.
A good strategy to modulate it includes a diet rich in natural antioxidants (fruits, vegetables, extra virgin olive oil, nuts) and compounds with an anti-inflammatory effect, such as the curcumin present in turmeric.
Scientific evidence indicates that these compounds help reduce discomfort without interfering with training adaptations.
Taking care of inflammation does not mean eliminating it, but keeping it under control to promote recovery.
What role does collagen play in joint health?
Collagen is the protein that gives structure, elasticity and resistance to connective tissues.
With age or training load, their production decreases, which can result in less regenerative capacity.
An adequate supply of collagen – together with a diet rich in vitamin C and quality proteins – promotes the repair of cartilage and tendons and helps maintain mobility and joint strength.
What habits help prevent joint discomfort in winter?
- Warm up well before exercise to activate circulation.
- Keep the muscles warm with appropriate clothing or active movements between sets.
- Take care of hydration, even if the feeling of thirst is less.
- Get enough sleep, as tissue regeneration occurs mostly during a night's rest.
- Follow a diet rich in fruits, vegetables, proteins and healthy fats, which provides all the nutrients involved in the repair of connective tissue.
