Infrared Weight Loss Therapy
Dr. Oz swears by infrared saunas for weight loss, detox and overall health. Far infrared saunas detoxify the body and burn up to to 600 calories in 30 minutes while fighting inflammation and pain.

Health benefit claims
A study of patients with rheumatoid arthritis and ankylosing spondylitis showed a reduction in pain, stiffness and fatigue during infrared sauna therapy, but this could have been due only to chance (i.e. not the sauna) as "these did not reach statistical significance."
Another benefit claim is that since saunas increase perspiration, they purportedly liberate undisclosed "toxins." Saunas have been recommended for this ostensible reason to people who are told they have high levels of "toxicity" in their body, although the supposed, offending toxins are rarely identified. Saunas may be useful to those who cannot sweat from exercise due to their health problems, such as Chronic Fatigue Syndrome.
Only if the sauna uses far-infrared technology, the sauna might be more tolerated by patients who don't tolerate the high temperatures of the standard humid hot air saunas. This is because far-infrared rays do not heat the air inside the sauna, but they still heat the body. However, most infrared saunas in the market do not use the expensive far-infrared panels, which can be touched because they remain always cold, but much cheaper low and medium-infrared heaters, which remain very hot when used and also heat the air of the sauna.
On the other hand, hyperthermia generated by infrared saunas may kill or weaken tumor cells, and is controlled to limit effects on healthy cells. Tumor cells, with a disorganized and compact vascular structure, have difficulty dissipating heat. Hyperthermia may therefore cause cancerous cells to undergo apoptosis in direct response to applied heat, while healthy tissues can more easily maintain a normal temperature. Even if the cancerous cells do not die outright, they may become more susceptible to ionizing radiation therapy or to certain chemotherapy drugs, which may allow such therapy to be given in smaller doses.
