Health Benefits of Infrared Sauna (Backed by Research)
Infrared saunas use infrared light to heat the body directly, rather than heating the air like traditional saunas. This allows for sweating and therapeutic effects at lower temperatures (120–150°F or 49–65°C). Research suggests several health benefits:
1. Cardiovascular Health
Infrared sauna therapy can improve heart health by promoting better circulation and reducing blood pressure. A study in JAMA Internal Medicine (2015) found that frequent sauna use (4–7 times per week) was associated with a 50% lower risk of fatal heart disease. Infrared therapy specifically enhances blood vessel function, reducing stiffness and improving oxygen delivery.
A 2016 study in The Journal of Complementary and Alternative Medicine reported that infrared sauna sessions lowered blood pressure in hypertensive patients after three months of regular use.
2. Pain Relief & Muscle Recovery
Infrared heat penetrates deeper into tissues (1.5 inches), improving blood circulation and reducing inflammation. A 2009 study in Clinical Rheumatology found that infrared sauna therapy reduced pain and stiffness in fibromyalgia patients.
Additionally, a 2015 study in The Journal of Human Kinetics concluded that infrared saunas help with muscle recovery by reducing soreness and increasing flexibility in athletes.
3. Detoxification & Skin Health
Sweating helps the body eliminate toxins like heavy metals (lead, cadmium, mercury) and BPA. A 2012 review in Environmental Science and Pollution Research found that sauna-induced sweating can facilitate the excretion of toxic elements from the body.
Infrared heat also improves skin elasticity, increases collagen production, and may help with acne by opening pores and reducing inflammation (Dermatology, 2006).
4. Mental Health & Stress Reduction
Infrared sauna sessions promote relaxation by stimulating the release of endorphins and lowering cortisol levels. A 2018 study in Psychosomatic Medicine found that regular sauna use reduced symptoms of anxiety and depression.
Heat exposure also boosts brain-derived neurotrophic factor (BDNF), which supports cognitive function and mental clarity (Age and Ageing, 2017).
5. Immune System Support
Infrared saunas may enhance immune function by stimulating white blood cell production. A 2013 study in The Journal of Human Kinetics found that sauna bathing boosted the immune response, potentially making the body more resistant to infections.
Conclusion
Infrared saunas provide significant health benefits, including cardiovascular support, pain relief, detoxification, and mental well-being. They offer a gentler alternative to traditional saunas, making them suitable for people who cannot tolerate high heat. However, individuals with certain medical conditions should consult a doctor before using infrared therapy.
