In an article in the Townsend Letter for Doctors and Patients, Lawrence Wilson, MD, wrote, “If I were to single out one method to combat cancer, it is the sauna. It assists removal of chemical toxins and heavy metals, increases oxygenation, enhances the immune system, and reduces the radiation burden in the body.” Infrared sauna treatments are harmful only to malignant cells that just can’t take the heat! Normal, healthy cells are immune to infrared radiation.
