The Benefits of Infrared Sauna

Interesting studies have shown that sweating is an effective way to remove heavy metals, such as arsenic, cadmium, lead and mercury. Here is a quote from the abstract on PubMed:

“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 severalfold 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.”

Another study showed that sweating assists the elimination of BPA. In some individuals, BPA was detected in sweat, even though they aren’t detected in blood or urine.

Phthalates exposure is extremely widespread as well. This study showed that phthalates are found in sweat but not blood of several individuals, and concentration in sweat was more than twice as high as urine levels on average.

Sweating is an essential way our body cleanses itself, and the above studies suggested that it may be the most effective way to eliminate heavy metals, BPA and phthalates. Because infrared heat penetrates deeper into the body tissues compared to a traditional sauna, it can work up a sweat and stimulate the release of fat-soluble toxins without burning up the skin at a high temperature. Are benefits are:

• improving circulation and increasing warmth
• raising core body temperature to fight infection
• reducing inflammation and preventing joint pains
• activating the parasympathetic nervous system and promoting relaxation
