Gout—a pain infrared sauna for chronic painful inflammatory form of arthritis triggered by uric acid crystal buildup in joints—affects millions of people worldwide. If you've experienced a gout attack, you know the intensity of the pain and swelling, and the desperation to find relief. In recent years, infrared saunas have gained attention as a potential complementary therapy for gout and other inflammatory conditions. But does the science support this claim?
The short answer is nuanced. While infrared sauna therapy shows promise for certain inflammatory and circulatory conditions, the evidence specifically for gout is limited and largely indirect. This article breaks down what we know about infrared saunas, inflammation, and gout—separating evidence-based insights from marketing hype. infrared sauna for inflammation and pain
How Infrared Saunas Differ from Traditional Saunas
Before evaluating gout relief, it's important to understand what makes infrared saunas unique.
Traditional Finnish dry saunas heat the air to high temperatures (typically 80–100°C), which then heats your body. Infrared saunas, by contrast, use infrared light wavelengths to penetrate tissue directly, raising core body temperature at lower ambient air temperatures (usually 40–65°C). This allows for a gentler, longer-duration session that some users find more tolerable.
The distinction matters because most large-scale sauna research—including landmark studies on cardiovascular disease, dementia, and mortality—comes from traditional Finnish sauna cohorts. While some infrared-specific research exists (particularly the Japanese "Waon" sauna studies), direct evidence for infrared saunas is far smaller than for traditional saunas.
Infrared Saunas and Inflammation: The Theoretical Case
Gout is fundamentally an inflammatory disease. When uric acid crystals deposit in a joint (commonly the big toe), they trigger an intense innate immune response—white blood cells attack the crystals, releasing inflammatory cytokines and causing the characteristic swelling, redness, and pain.
Heat therapy's theoretical anti-inflammatory potential:
-
Vasodilation and blood flow — Infrared heat promotes vasodilation (widening of blood vessels), which could theoretically improve blood flow to affected joints, delivering oxygen and nutrients while diluting inflammatory mediators.
-
Heat-shock proteins (HSPs) — When cells are exposed to heat stress, they upregulate production of heat-shock proteins, which have documented anti-inflammatory and cytoprotective properties in laboratory and animal studies.
-
Sympathetic nervous system activation — Some research indicates that passive heat exposure activates the sympathetic nervous system and triggers hormonal responses (Iguchi et al., 2012), including release of catecholamines, which can modulate inflammation. However, this evidence comes from acute heat-chamber studies in healthy young adults, not chronic sauna use in gout patients.
-
Uric acid solubility — Theoretically, increased core temperature and perspiration could promote uric acid excretion through sweat, though this mechanism is not well-established in clinical practice.
While these mechanisms are plausible, none has been rigorously tested in gout patients specifically. The inflammatory response in gout is distinct from other conditions like rheumatoid arthritis or fibromyalgia, and what works for one may not transfer directly to another.
What Research Shows About Infrared Saunas and Joint Conditions
The closest relevant evidence comes from studies on infrared saunas and rheumatologic conditions.
Rheumatoid Arthritis and Ankylosing Spondylitis
One pilot study examined infrared sauna use in patients with rheumatoid arthritis (RA) and ankylosing spondylitis (AS). In this trial of 34 patients (17 with RA, 17 with AS), participants completed 8 infrared sauna sessions over 4 weeks. Results showed that pain and stiffness fell significantly within individual sessions (RA p<0.05, AS p<0.001), with no adverse effects reported (Oosterveld et al., 2009). However, the 4-week trend was non-significant, and there was no control arm, making it difficult to distinguish sauna effects from natural disease fluctuation or placebo response.
The take-home: Infrared saunas may provide acute, within-session pain relief for inflammatory joint conditions, but longer-term benefit is unclear.
Fibromyalgia
A small study of 13 female fibromyalgia patients found that far-infrared Waon sauna therapy reduced pain by roughly 50% after the first session, with the effect remaining stable over approximately 14 months (Matsushita et al., 2008). While encouraging, this was a single-arm, uncontrolled study, so causality cannot be assumed. Fibromyalgia is a centralized pain condition quite different from gout, limiting generalizability.
The Missing Evidence: Gout-Specific Infrared Sauna Trials
Despite these preliminary findings in other inflammatory arthropathies, there are no published randomized controlled trials specifically testing infrared saunas for acute or chronic gout management. This is a critical gap. Gout's pathophysiology—monosodium urate crystal-driven acute inflammation followed by intercritical periods—is unique and requires dedicated study.
Without gout-specific trials, any recommendation must remain cautious and preliminary.
Urate Excretion and Sweat: Can Saunas Help Lower Uric Acid?
One of the most commonly cited claims is that saunas help "flush out" uric acid through sweat, thereby reducing serum urate and gout risk. However, this claim is not well-supported by clinical evidence.
While one small observational study found that various toxic elements appeared in sweat samples collected during induced sweating, including elements not detectable in serum (Genuis et al., 2011), this does not establish that sauna-induced sweating clinically reduces serum urate or prevents gout attacks. The study involved only 20 participants, no control group, and no measurement of clinical outcomes. Moreover, sweat samples can be contaminated by topical sources, complicating interpretation.
The kidneys, not sweat glands, are the primary route for urate excretion. Any benefit of saunas on serum urate would have to work indirectly—perhaps through improved renal perfusion or systemic effects on urate metabolism—rather than direct urinary or cutaneous excretion.
Bottom line: There is no rigorous evidence that regular sauna use lowers serum uric acid or reduces gout incidence.
Safety Considerations: When Infrared Saunas May Be Risky for Gout
While heat therapy can be soothing during intercritical periods (between gout attacks), infrared saunas carry risks during an acute gout attack:
-
Increased inflammatory response — Some evidence suggests that heat can transiently increase inflammatory mediator release. Applying heat directly to an actively inflamed joint may worsen pain and swelling in the short term.
-
Dehydration — Gout is exacerbated by dehydration, which increases serum urate concentration. Prolonged sauna use causes fluid loss through sweating; inadequate rehydration could trigger or worsen an attack.
-
Medication interactions — If you take urate-lowering drugs (allopurinol, febuxostat) or anti-inflammatory agents (NSAIDs, colchicine, corticosteroids), heat exposure could potentially alter drug metabolism or absorption, though this is not well-studied.
-
Cardiovascular stress — In vulnerable patients, the hemodynamic load of sauna use (increased heart rate and cardiac output) may pose risk.
If you have gout, consult your rheumatologist or primary care physician before regular infrared sauna use.
A Realistic View: Infrared Saunas as Adjunctive, Not Curative
The broader evidence on infrared and traditional saunas suggests benefits for cardiovascular health, circulation, and some inflammatory conditions—but gout is not yet among them. Studies on cardiovascular benefits, for instance, come largely from observational cohorts of traditional Finnish sauna users, not infrared sauna trials, and even then, they show association, not proven causation (Laukkanen et al., 2015, 2018).
For rheumatologic conditions, infrared saunas may offer acute symptom relief (pain reduction within sessions) in some patients. But chronic, disease-modifying benefit is not established, and gout-specific evidence is absent.
If you are considering infrared saunas for gout:
-
Do not replace conventional therapies. Urate-lowering drugs (allopurinol, febuxostat) and acute anti-inflammatory treatment (colchicine, NSAIDs, corticosteroids) remain the evidence-based standard of care.
-
Use during intercritical periods only. Avoid sauna use during an active gout attack.
-
Stay well-hydrated. Drink plenty of water before, during, and after sauna use to offset fluid loss.
-
Monitor your response. Keep a symptom diary to track whether sauna sessions correlate with gout attacks, pain levels, or uric acid readings (if monitored).
-
Talk to your doctor. Discuss infrared sauna use with your physician, especially if you take medications or have comorbidities.

Frequently Asked Questions
Q: Can an infrared sauna cure gout?
A: No. There is no evidence that infrared saunas cure gout or permanently lower uric acid levels. Gout requires medical treatment (urate-lowering drugs, anti-inflammatory medications) and lifestyle changes (diet, hydration, weight loss). Infrared saunas may serve as a complementary therapy for comfort during remission, but should never replace conventional care.
Q: Is it safe to use an infrared sauna during a gout attack?
A: No. During an acute attack, heat may transiently increase inflammation and swelling. Additionally, sweating increases dehydration, which can raise serum urate and prolong symptoms. Wait until inflammation has fully resolved before resuming sauna use.
Q: How often should I use an infrared sauna if I have gout?
A: There is no evidence-based recommendation for gout patients. If your physician approves sauna use, start conservatively—perhaps once weekly for 15–20 minutes—and monitor your response. Never use saunas as a substitute for prescribed urate-lowering therapy or acute gout treatment.
Q: Does sweating in a sauna help eliminate uric acid?
A: Sweat is not a primary route for urate excretion; the kidneys handle roughly 90% of urate elimination via urine. While some research indicates that trace toxins appear in sweat, there is no clinical evidence that sauna-induced sweating meaningfully reduces serum uric acid or prevents gout attacks.
Q: Are infrared saunas safer than traditional saunas for gout?
A: Both infrared and traditional saunas carry the same theoretical risks for gout patients: acute heat can exacerbate inflammation, sweating can cause dehydration, and no form of sauna has proven efficacy for gout management. The choice between them (if your doctor approves sauna use at all) should be based on personal tolerance and comfort rather than gout-specific benefits.
Conclusion
Infrared saunas may offer comfort, relaxation, and potential acute pain relief for some inflammatory joint conditions—but the evidence specifically for gout is absent. While heat's anti-inflammatory properties are theoretically promising, and while some studies show acute benefits in other rheumatologic diseases, no rigorous trials have tested infrared saunas in gout patients.
Serum uric acid is best managed through medical therapy, dietary modification, and hydration—not sauna use. If you have gout and are interested in infrared saunas, approach them as a complementary wellness tool for comfort during remission, never as a primary or replacement treatment. Always consult your healthcare provider before starting regular sauna use, especially if you are taking gout medications or have active disease.
The journey to gout relief is best taken with evidence-based medicine at its core.
