The far infrared sauna works by raising the internal temperature of the body, which causes blood vessels to dilate and boosts blood flow. Increased blood flow can aid in the reduction of inflammation by supplying new oxygen and nutrients to inflamed regions. Far-infrared saunas can also increase the creation of heat shock proteins, which aid in the repair of injured cells and tissues.

Far infrared sauna treatment has been shown in studies to reduce inflammation in a variety of illnesses, including rheumatoid arthritis, chronic pain, and cardiovascular disease. Patients with rheumatoid arthritis who received far infrared sauna treatment reported substantial decreases in pain and stiffness, as well as increases in general physical performance, according to one research.

Far infrared sauna treatment has also been shown to decrease inflammation in people with chronic pain conditions like fibromyalgia and chronic fatigue syndrome. Individuals with fibromyalgia who received far infrared sauna treatment reported substantial reductions in pain and fatigue, as well as increases in sleep quality, according to one research.

Far infrared sauna treatment has been shown to have additional health advantages, such as better circulation, detoxification, and stress reduction, in addition to decreasing inflammation in the body.
