Fevers, Colds, Influenza, and many other common diseases often induce a fever, which is our body’s natural way of burning off toxins and bacteria associated with the illness. When using a Far Infrared Sauna, skin temperature rises to 104°F and internal body temperature rises to about 100.4°F, thus creating an artificial fever state, a process known as hyperthermia. Fever is part of the body’s natural healing process. Fever stimulates and boosts the immune system, resulting in increased production of disease fighting white blood cells, antibodies and interferon (an anti-viral protein with cancer fighting capability). Recent studies also show that symptoms of colds and flu-like illnesses are dramatically reduced if Far Infrared Sauna Therapy is used in its early stages.
