Infrared sauna for fibromyalgia โ natural relief
Infrared sauna for fibromyalgia โ natural relief from pain and stiffness
Chronic pain, stiff muscles and persistent fatigue: fibromyalgia has a profound impact on daily life. More and more people are discovering how infrared heat can bring calm and relief, simply from home.
Fibromyalgia is a chronic condition that causes widespread pain, fatigue and stiffness. Alongside medical treatment, many people look for complementary ways to ease their symptoms. Infrared therapy โ via a sauna or sauna blanket โ is mentioned more and more often. In this article: what fibromyalgia actually is, how heat affects pain and the nervous system, what the science says, and how to use an infrared sauna blanket safely and effectively with fibromyalgia.
What is fibromyalgia?
Fibromyalgia is a chronic pain syndrome characterised by widespread pain throughout the body, accompanied by extreme fatigue, sleep problems, stiff muscles and joints and sometimes concentration problems (also known as "fibro fog"). The condition affects an estimated 2 to 4 percent of the population and is considerably more common in women than in men.
The exact cause of fibromyalgia is not yet fully understood. Researchers suspect it is related to a disturbance in the way the central nervous system processes pain signals. The body then becomes oversensitive to stimuli that would normally cause little or no pain.

Because fibromyalgia cannot be detected through standard blood tests or imaging, the diagnosis is usually made on the basis of symptoms and by ruling out other conditions. This makes the process long and frustrating for many people.
How heat works with fibromyalgia
Heat therapy has been used for centuries for pain relief and muscle relaxation. With fibromyalgia, heat plays an interesting role because it acts on several levels at once: muscles, nervous system and mental relaxation.
When your body is exposed to deep infrared heat, a number of things happen:
- Blood vessels dilate โ circulation improves, so oxygen and nutrients reach muscles and tissues more quickly.
- Muscles relax โ tense, cramped muscles let go, reducing stiffness.
- The nervous system calms down โ the parasympathetic (rest-and-recover) mode is activated.
- Endorphins are released โ these natural painkillers produce a natural feeling of relief.
Infrared works differently from a traditional sauna. In a normal sauna, the hot air warms your skin. With infrared (FIR, Far Infrared Rays), the radiation penetrates deep into your tissues โ a 360-degree warmth from within. Read more about exactly how this works in our explanation of the Flamengo sauna blanket.
What does research say about infrared for fibromyalgia?
Several small-scale studies have looked at the effect of infrared therapy on fibromyalgia. The results are cautiously positive.
A Japanese study published in Internal Medicine followed 13 women with fibromyalgia who used an infrared sauna combined with light exercise twice a week for 12 weeks. Afterwards, all participants reported a significant reduction in pain (on average 31 to 77 percent), and this improvement was largely maintained at long-term follow-up.
Other research suggests that regular use of infrared heat may contribute to better sleep quality, less stress and lower pain levels in people with chronic pain conditions. It is important to stress that this is complementary support, not a replacement for medical advice.
Benefits of an infrared sauna for fibromyalgia
Based on research and user experiences, the following benefits are mentioned most often with regular use of an infrared sauna or sauna blanket.
The deep FIR heat penetrates into the muscles and joints, releasing built-up tension. Many people with fibromyalgia experience less pain in their arms, legs and back after a session โ often right after the first few sessions.
With fibromyalgia, the nervous system is often in a heightened state of alert. Heat helps calm the system, which can have a direct and lasting influence on pain levels and feelings of restlessness.
Improved circulation removes waste products more quickly and brings oxygen and nutrients to the tissues. This supports the body's natural recovery process. Read more in our article on improving blood circulation with infrared.
Sleep problems are one of the most difficult aspects of fibromyalgia. The relaxing effect of a session shortly before bedtime can help you fall asleep faster and sleep more deeply.
Stress is a well-known trigger for fibromyalgia flares. The ritual moment of rest that a sauna session offers helps reduce mental tension and puts the body into rest mode.
For people looking for ways to support (not replace) their medication, regular infrared therapy is a valuable addition to existing pain management โ without side effects or dependency.
Fibromyalgia and rheumatism โ what is the difference?
Many people wonder what the difference is between fibromyalgia and rheumatism. The symptoms often look similar at first glance โ both cause pain and stiffness โ but they are fundamentally different conditions.
| Feature | Fibromyalgia | Rheumatism (rheumatoid arthritis) |
|---|---|---|
| Nature | Central pain syndrome | Autoimmune disease |
| Main symptom | Widespread pain + fatigue | Inflamed joints |
| Detectable | No blood marker | Blood tests + imaging |
| Damage | No permanent tissue damage | Can cause joint damage |
| Does heat help? | Often yes | Yes, for chronic complaints |
Both conditions can benefit from heat therapy, but for different reasons. With fibromyalgia, heat helps calm the oversensitive nervous system. With rheumatism, heat can relax cramped muscles around inflamed joints โ although for acute inflammation, cold is often recommended instead. If in doubt, consult your doctor or rheumatologist.
The Flamengo toolkit for fibromyalgia
For people with fibromyalgia, we see three tools from our range that are used most โ each for a different aspect of the complaints: the whole body (sauna blanket), back, neck and shoulders (InfraStretch massage mat) and specific joints (InfraPulse vibration massage).
Three Flamengo tools for relief with fibromyalgia โ for the whole body, the upper body and the joints.
How do you best use them together?
Many customers with fibromyalgia follow a fixed weekly rhythm โ this gives the best effect and prevents overstimulation.
| Moment | Tool | What it does |
|---|---|---|
| Morning stiffness | InfraStretch (15 min) | Loosens back and neck with morning stiffness |
| For joint pain | InfraPulse on the painful spot | Targeted heat and vibration on knee, shoulder or elbow |
| 3-5x per week, evening | Sauna blanket (30-45 min) | Deep relaxation of the nervous system and muscles |
| With severe tension | Sauna blanket + light stretching | Releases muscle tension in combination with heat |
This sounds like a lot โ but these are calm sessions in which you simply lie and relax. Total active effort: minimal. Effect on complaints: significant, provided you keep it up consistently.
How do you use a sauna blanket with fibromyalgia?
People with fibromyalgia can be extra sensitive to temperature. That is why it is important to start carefully and build up your sessions gradually.
Three phases for safe, gradual use of an infrared sauna blanket with fibromyalgia.
Recommended temperature
Always start at 50 to 60 degrees. Your body gradually gets used to the deep heat and you can sense how you respond. After a few sessions you can carefully build up to 60 to 65 degrees. An infrared sauna blanket feels different from a traditional sauna: the warmth comes from within, not through hot air. Many people with fibromyalgia find this more comfortable.
Session length
Start with 20 minutes per session and gradually build up to 30 to 45 minutes. A maximum of 60 minutes is enough. Always listen to your body: if you feel dizzy, uncomfortable or too hot, stop immediately.
Frequency
For the best effect we recommend 2 to 3 sessions per week at the start. Once you notice that your body responds well, you can build up to 3 to 5 sessions per week. A fixed rhythm gives the best results. You can read more about this in how often using a sauna is healthy.
Tips for people with fibromyalgia
- Drink plenty of water before and after each session โ good hydration is essential.
- Start at a lower temperature than someone without fibromyalgia would.
- Plan a calm transition โ no busy activities straight after a session.
- Build a fixed rhythm: the same time of day helps your body adapt.
- Combine with deep breathing or light meditation for extra relaxation.
Sauna blanket or sauna cabin for fibromyalgia?
For people with fibromyalgia, a sauna blanket can be more practical than a traditional sauna or cabin. Here are the reasons at a glance.
| Aspect | Sauna blanket | Sauna cabin |
|---|---|---|
| Comfort when in pain | Lying down, body supported | Sitting upright |
| Access from home | Always available | Away from home or cabin needed |
| Energy costs | Low (650W) | High |
| Investment | From โฌ449 | โฌ2,000+ |
| Storage | Foldable | Fixed location |
For those who regularly suffer from fibromyalgia flares, it is valuable to have quick access to heat therapy โ without having to leave the house. A sauna blanket offers that flexibility, even on days when being physically active is difficult.
What should you watch out for?
Although an infrared sauna blanket is safe for most people, there are situations in which extra caution is needed.
- are pregnant;
- have heart problems or high blood pressure;
- have diabetes or reduced sensitivity to heat;
- have a pacemaker or metal implants where the blanket is placed;
- take medication that affects your response to heat;
- experience heat intolerance as part of your fibromyalgia;
- have recently had surgery or have an open wound.
A small proportion of people with fibromyalgia experience "heat intolerance", where heat actually triggers more pain or fatigue. If that applies to you, a lower temperature or shorter session can make the difference. Stop immediately if you feel unwell and discuss this with your healthcare provider.
Frequently asked questions about infrared and fibromyalgia
Limited scientific research points to a positive effect on pain, fatigue and stiffness in people with fibromyalgia. For many people it works as a valuable addition to medical treatment, but results vary from person to person. Never replace medical care with heat therapy alone.
Start with 2 to 3 sessions per week and slowly build up to 3 to 5 sessions once you notice that your body responds well. Consistency gives the best effect โ a regular ritual works better than an occasional long session.
Start at 50 to 60 degrees. People with fibromyalgia can be extra sensitive to heat, so always start lower than an average user. If it feels comfortable, slowly build up to 60 to 65 degrees.
Start with 20 minutes per session and gradually build up to 30 to 45 minutes. A maximum of 60 minutes is enough. Stop immediately if you feel uncomfortable or dizzy.
Fibromyalgia is a central pain syndrome without visible tissue damage. Rheumatism (rheumatoid arthritis) is an autoimmune disease that does cause inflammation and joint damage. Both can benefit from heat therapy, but the mechanisms are different.
Many people find that a calm sauna session at a lower temperature brings relief during a flare in particular. But listen carefully to your body โ with severe exhaustion or intense pain, resting without heat may be better. If in doubt, consult your healthcare provider.
For many people with fibromyalgia, a sauna blanket is more comfortable because you can relax lying down while your body is fully supported. A sauna blanket is also always immediately available at home, which is handy on days when leaving the house is difficult.
No. Fibromyalgia is a chronic condition for which there is no cure (yet). Heat therapy helps relieve symptoms and improve quality of life, but does not replace medical treatment. It is a complement, not a solution.
Conclusion
An infrared sauna can be a valuable addition to your daily pain management with fibromyalgia โ not a miracle cure, but a natural way to relieve pain, stiffness and stress. The science is cautiously positive, and thousands of users worldwide experience relief from their symptoms. Start slowly, listen to your body and build up gradually. For those who prefer to relax at home, an infrared sauna blanket offers the flexibility to take your well-being into your own hands.
