"In individuals with higher exposure or body burden, sweat generally exceeded plasma or urine concentrations, and dermal could match or surpass urinary daily excretion. Arsenic dermal excretion was several-fold higher in arsenic-exposed individuals than in unexposed controls. Cadmium was more concentrated in sweat than in blood plasma. Sweat lead was associated with high-molecular-weight molecules, and in an interventional study, levels were higher with endurance compared with intensive exercise. Mercury levels normalized with repeated saunas in a case report. Sweating deserves consideration for toxic element detoxification. Research including appropriately sized trials is needed to establish safe, effective therapeutic protocols." (Arsenic, Cadmium, Lead, and Mercury in Sweat: A Systematic Review)
Another study shows benefit for chronic pain and also for illness related to environmental toxin exposure;
"Studies document the effectiveness of sauna therapy for persons with hypertension, congestive heart failure, and for post-myocardial infarction care. Some individuals with chronic obstructive pulmonary disease (COPD), chronic fatigue, chronic pain, or addictions also find benefit. Existing evidence supports the use of saunas as a component of depuration (purification or cleansing) protocols for environmentally-induced illness." (Sauna as a valuable clinical tool for cardiovascular, autoimmune, toxicant-induced and other chronic health problems)
Japanese study shows increases in patient's mood after sauna use. They also cite detoxing of heavy metals. (Psychological Characteristics after Far-infrared Hyperthermia Evaluated Using the Profile of Mood State (POMS) )
Firefighters use infrared saunas to detox after being exposed to toxins in smoke
Firefighters are exposed to many toxins from smoke and debris. Using an infrared sauna is one important way they can eliminate these toxins. (IFD firefighters sweat out dangerous toxins to fight back against growing cancer epidemic)
Sauna detoxing has been used on people who were exposed to toxins on 9/11. Here is a report about detoxing which includes dioxins.(Health Status of Rescue Workers Improved by Sauna Detoxification)
Study shows far infrared reduces pain and increases tissue repair in wounds. (The Application of Far-Infrared in the Treatment of Wound Healing)
Mary shows us how many metals and chemicals are detoxed using saunas
Our report on heavy metal detoxing. A relax sauna user named Karen Russell had heavy metal toxicity issues and was able to reduce her heavy metal blood levels back to safe levels. Read her story here(Relax Sauna Detox Testimonials)
