Eczema is a common inflammatory skin condition that causes dry, itchy, and red patches on the skin. Infrared saunas use infrared light to generate heat, which directly penetrates the body rather than just warming the surrounding air. This article explores the potential relationship between infrared sauna use and eczema management.
Understanding Eczema and Infrared Saunas
Eczema, also known as atopic dermatitis, is a chronic skin disorder characterized by inflammation, dryness, and itchiness. Its development involves factors like genetics, immune system responses, and environmental triggers such as irritants, allergens, and stress. A compromised skin barrier is a hallmark, allowing irritants to enter and moisture to escape, leading to dryness and reactivity.
Unlike traditional saunas that heat the air, infrared saunas use invisible light waves, including near, mid, and far infrared, to directly warm the body. This allows deeper heat penetration at lower ambient temperatures, typically 100°F to 140°F (37°C to 60°C), for a more comfortable experience.
How Infrared Saunas Might Influence Eczema
The relaxing environment of an infrared sauna can help reduce stress, which is a known trigger for eczema flare-ups. The heat from infrared saunas promotes increased blood flow and circulation, delivering more oxygen and nutrients to the skin. This enhanced circulation may support skin health and aid in the removal of waste products.
Sweating is a natural process for eliminating waste, and infrared saunas can induce a deeper sweat. While some suggest sweating removes impurities that might aggravate the skin, scientific evidence specifically linking sweat-induced “detoxification” to eczema improvement is limited. Infrared light has also been associated with anti-inflammatory properties, with research indicating it can reduce inflammatory markers and promote healing, potentially benefiting inflamed skin.
Potential Risks and Important Considerations
Sweating in an infrared sauna can lead to fluid loss, potentially exacerbating dry skin, a primary symptom of eczema. Adequate hydration is important before, during, and after a sauna session to counter this effect. Excessive heat can also trigger flare-ups for some individuals with eczema, leading to increased itching or redness. The salt and minerals in sweat can irritate sensitive, eczematous skin.
Warm, moist environments, like saunas, can potentially increase the risk of bacterial or fungal growth. A compromised skin barrier, typical in eczema, might make individuals more susceptible to such infections. Overheating and exhaustion are general sauna risks, which can be more pronounced for someone managing a chronic condition. Starting with short sessions (10-15 minutes), monitoring skin reactions, and ensuring proper hydration are precautions to consider.
Current Research and Medical Guidance
Currently, there is limited high-quality scientific research specifically investigating the effectiveness of infrared saunas as a primary treatment for eczema. Evidence regarding potential benefits is largely anecdotal or extrapolated from general heat therapy effects on skin health. Some studies suggest infrared light can improve skin texture or reduce inflammation, but these findings are not consistently linked directly to eczema treatment.
Infrared saunas are not recognized as a standalone medical treatment for eczema and should not replace prescribed therapies. Individual responses to sauna use can vary, with some people finding relief and others experiencing worsening symptoms. It is recommended to consult with a dermatologist or healthcare provider before incorporating infrared sauna use, especially for individuals with severe eczema, open wounds, or other medical conditions. If considered, infrared sauna use should be viewed as a complementary activity, not a primary treatment.
