Fibromyalgia and weather: how does it affect affect your pain?

What is fibromyalgia? 

Fibromyalgia is a chronic condition characterized by widespread pain in the muscles and joints, intense fatigue and sleep disorders. It mainly affects women and can have a profound impact on daily, professional and social life. Patients often experience additional symptoms such as headaches, cognitive disorders or increased sensitivity to temperature changes, noise or light.

Although its exact causes remain poorly understood, fibromyalgia involves a disruption of the central nervous system, which amplifies pain perception and makes the body more sensitive to stimuli, including climatic variations. This hypersensitivity is the key to understanding why weather can sometimes make pain and discomfort worse.

Why does weather affect fibromyalgia pain? 

The role of atmospheric pressure and humidity 

Changes in atmospheric pressure are often mentioned as one of the reasons for discomfort by people with fibromyalgia. When pressure drops, body tissues can expand slightly, putting additional strain on muscles, joints and nerves that are already hypersensitive. This could explain why some people experience more pain before rain or during sudden changes in weather.

Humidity, on the other hand, tends to increase muscle stiffness and the feeling of heaviness in the body. It can also influence nerve conductivity and aggravate the perception of pain. While scientists remain divided on the direct link between weather and symptom intensity, patient reports are numerous and consistent: high humidity and changes in pressure often cause an increase in pain.

Cold, humidity, heat: what is their impact on your body? 

Cold naturally causes muscle contraction in order to preserve body heat. In people with fibromyalgia, this reaction can increase muscle tension and pain, also leading to fatigue.

In addition to its mechanical effects, humidity often creates a feeling of tightness in the joints and tissues. Some people describe diffuse pain and increased stiffness, particularly upon waking or after a period of inactivity.

Conversely, heat is often perceived as soothing. It promotes muscle relaxation and improves blood circulation. However, in some patients, excessive heat can also increase fatigue, cause headaches or accentuate general discomfort. The ideal weather for fibromyalgia patients is therefore very personal and depends on each person's sensitivity.

Hypersensitivity of the central nervous system 

Fibromyalgia is primarily caused by a disorder of the central nervous system: the brain and spinal cord process pain signals in an amplified manner. This hypersensitivity, known as ‘hyperalgesia’, makes the body more reactive to various stimuli, including climatic variations.

Some researchers suggest there is a link with neurotransmitters, particularly serotonin and dopamine, which are involved in regulating pain, mood and sleep. When the weather changes, variations in pressure or temperature can be interpreted by the brain as a danger signal, triggering an exaggerated response. In other words, the brain ‘perceives’ these changes as more intense than they really are, thereby amplifying the pain.

The seasons and fibromyalgia: when the pain gets worse 

Winter: not an easy season

Winter is often a difficult season for people with fibromyalgia. Cold weather, humidity and lack of light can exacerbate muscle stiffness, widespread pain and fatigue. The decrease in natural light also disrupts the production of melatonin and serotonin, affecting both sleep and mood.

Many patients also report seasonal affective disorder, a low mood that also amplifies the perception of pain. Short days, lack of outdoor activity and isolation reinforce this vicious circle of pain, fatigue and low mood.

Summer heat: friend or foe? 

While heat can relieve muscle tension, summer does not always bring relief. Excessive heat can cause headaches or a drop in energy, especially in case of dehydration. Sleep can also be disrupted, which increases fatigue and pain.

Each person with fibromyalgia reacts differently: some feel better in hot, dry climates, while others suffer more because of the heat. The key is to learn to listen to your body and adapt.

Spring and fall: difficult transitional periods

These two seasons, with their rapid changes in temperature and atmospheric pressure, can be particularly uncomfortable. The body struggles to adapt, and these fluctuations can reactivate joint and muscle pain. Many patients describe the worsening of symptoms during these sudden changes in weather.

How can you manage your fibromyalgia despite weather and climate change? 

Adjusting your environment 

Maintaining a stable indoor environment is essential. A mild, constant temperature, good insulation and moderate humidity help reduce discomfort. Using hot water bottles, thermal clothing or heated blankets helps to relieve tense muscles. Ensuring good air quality by regularly ventilating rooms and limiting humidity also improves overall well-being.

Taking care of your body 

Gentle physical activity, such as yoga, walking or swimming in warm water, helps maintain muscle flexibility and reduce pain. An anti-inflammatory diet, rich in fruit, vegetables and omega-3 and low in refined sugars, can also have a beneficial effect.

Staying well hydrated is essential, as is getting a good night's sleep. Regular routines, going to bed at set times and a calm environment promote better recovery.

Taking care of your mental health 

Stress amplifies pain. Learning to manage stress through meditation, conscious breathing or sophrology techniques can help relieve tension.

Getting therapy or joining patient support groups can also help you feel understood and less isolated.

This is important! 

• Fibromyalgia is a chronic condition characterized by widespread pain, fatigue and sleep disorders, linked to hypersensitivity of the central nervous system.
  
• Cold weather, humidity and changes in atmospheric pressure can exacerbate pain and muscle stiffness.
  
• Each season has its own characteristics: winter and the transitional seasons (spring and fall) are often more difficult, while heat can provide relief but also cause fatigue in some patients.
  
• Adjusting your environment, engaging in gentle physical activity, adopting an anti-inflammatory diet and ensuring restful sleep are key levers for reducing the impact of weather.
  
• Stress management, therapy and support groups can help improve your pain management and thus quality of life.
