Do infrared saunas work? What the science says. 

From the innovative Incandescent Electric-Light Bath introduced by Dr. John Harvey Kellogg in 1893 to the modern-day popularity of infrared saunas, the concept of using heat therapy for various health benefits has come a long way. Infrared saunas have gained widespread attention for their potential to relax muscles, reduce stress, and detoxify the body. But do they actually work, and how should they be used?

Infrared saunas differ from traditional saunas in that they use lamps emitting specific infrared wavelengths of light to warm the body, rather than heating the air directly. This allows the heat to penetrate deep into the skin, potentially stimulating mitochondrial activity and promoting cellular regeneration. While the science is still evolving in this area, some experts believe that the deep penetration of infrared light can enhance cellular activity and support the body’s healing processes.

Research has shown that heat therapy, including that from infrared saunas, can have therapeutic benefits such as reducing blood pressure, improving blood vessel function, relieving muscle soreness, and increasing flexibility. Studies have also suggested that infrared saunas may help alleviate pain and stiffness in conditions like rheumatoid arthritis. However, claims of detoxification benefits from saunas are met with skepticism by some experts, who point out that true detoxification occurs internally through the lymphatic system and liver.

While infrared saunas offer potential health benefits, they may not be suitable for everyone. Individuals with certain health conditions like thyroid issues, autoimmune disorders, or neuropathy should avoid using saunas. It is important to stay hydrated while using an infrared sauna and limit sessions to 15-20 minutes per day. Ultimately, the decision to use an infrared sauna should be based on individual health considerations and goals for relaxation and well-being.

In conclusion, the use of infrared saunas as a form of heat therapy is a growing trend in wellness practices, with potential benefits for muscle relaxation, stress reduction, and overall well-being. While more research is needed to fully understand the mechanisms behind these benefits, many people find value in incorporating infrared sauna sessions into their self-care routines. Whether it’s for physical benefits or simply to unwind and reset mentally, the allure of the infrared sauna experience continues to attract a wide range of individuals seeking relaxation and rejuvenation.
