Does cold weather affect fibromyalgia pain?
In the United Kingdom, it is a common clinical observation that cold weather significantly impacts the severity of fibromyalgia symptoms. Many patients experience what is often termed a ‘winter flare,’ where pain becomes more intense, stiffness increases, and fatigue deepens as temperatures drop. While the exact biological mechanism is still being researched, the NHS and NICE guidelines recognise that environmental factors play a crucial role in managing chronic primary pain. In a sensitised nervous system, cold temperatures can act as a physical stressor, ‘turning up the volume’ on pain signals and making it harder for the body to maintain its internal balance.

The ‘Fight or Flight’ response to cold
For individuals with fibromyalgia, the central nervous system is often in a state of hyper-vigilance. Cold weather is perceived by the brain not just as a temperature change, but as a physical threat. When the skin detects a significant drop in temperature, it triggers the sympathetic nervous system, the ‘fight or flight’ response.
This response causes the blood vessels to constrict (vasoconstriction) to keep the core warm, and it increases muscle tension. In a healthy person, this is a minor adjustment. In someone with fibromyalgia, this added tension can trigger a significant increase in widespread pain and lead to a state of systemic exhaustion as the body uses up limited energy reserves trying to stay warm.
Barometric pressure and joint pain
It isn’t just the temperature that changes in the UK during winter; it is also the barometric pressure (the weight of the air). When a cold front approaches, the air pressure often drops. This drop in pressure can cause the tissues and fluids within the joints and muscles to expand slightly.
In a sensitised system, even this microscopic expansion can be detected as pain. This is why many patients report feeling ‘stiff to the bone’ or experiencing a deep, aching pain in their joints just before a storm or a cold snap. The NICE guidelines for chronic pain highlight that physical environment is a key factor in how pain is perceived and managed.
Temperature Dysregulation
Many people with fibromyalgia suffer from temperature dysregulation, meaning their body struggles to maintain a steady internal temperature. This often manifests as ‘Raynaud ’s-like’ symptoms, where fingers and toes become painfully cold and turn white or blue, or as a general inability to ‘get warm’ once chilled.
This dysregulation is linked to the autonomic nervous system. Because the body is working so hard to manage pain, it has fewer resources left to manage basic functions like temperature control. Once a person with fibromyalgia becomes cold, it can take hours of total rest and external heat to return their nervous system to a stable, less painful state.
Strategies for managing the ‘Winter Flare’
In the UK, management focuses on ‘shielding’ the nervous system from the cold to prevent the pain-tension cycle from starting:
- Layering and Fabrics: Wearing multiple thin layers is more effective than one thick layer, as it traps warm air. Natural fibres like wool or specialized thermal fabrics are recommended to help the body regulate temperature without overheating.
- External Heat Sources: Using electric blankets, wheat bags, or hot water bottles can provide the ‘manual’ heat the body is struggling to produce. Taking a warm (not hot) bath before bed can also help relax the ‘guarding’ muscles.
- Pacing Your Warmth: Don’t wait until you are shivering to add a layer. Proactively keeping your environment at a steady, comfortable temperature (around 18°C to 21°C) helps prevent the nervous system from entering a state of ‘cold-stress.’
Conclusion
Cold weather is a significant and documented trigger for fibromyalgia pain in the UK. By understanding that your body perceives the cold as a biological stressor, you can take proactive steps to protect your ‘energy envelope.’ Whether through careful layering, the use of external heat, or adjusting your pacing during the winter months, the goal is to keep your nervous system as calm as possible. While you cannot change the British weather, you can change how you insulate your body against its effects, helping to reduce the severity of winter flares and maintain a better quality of life throughout the colder season.

Why does my ‘brain fog’ get worse in the winter?
The brain uses a massive amount of energy to keep the body warm. If your system is struggling with the cold, it has fewer resources available for cognitive tasks like memory and concentration.
Is it safe to use a TENS machine in the cold?
Yes. Many patients find that using a TENS machine on a low setting helps to ‘distract’ the nervous system from the cold-induced pain signals.
Can Vitamin D deficiency make winter pain worse?
Absolutely. In the UK, we get very little Vitamin D from sunlight in winter. Low Vitamin D can cause deep bone and muscle pain that mimics or worsens fibromyalgia. The NHS recommends a daily supplement during autumn and winter.
Can my GP prescribe anything specific for winter flares?
While there isn’t a ‘winter-specific’ pill, your GP may review your dosage of medications like amitriptyline, which can help with sleep and pain modulation during more difficult months.
What is the ‘Raynaud’s’ connection?
While they are separate conditions, many fibromyalgia patients have Raynaud’s Phenomenon. Keeping your core warm is the best way to prevent the painful constriction of blood vessels in your hands and feet.
