What the Research on the Effectiveness of Induced Sweating and Toxin Elimination says:
Sweating helps eliminate phthalates
Phthalates are chemical compounds that are used frequently in plastics, household products and cosmetics.
“The phthalate family of chemical compounds are components of innumerable everyday consumer products, resulting in a high exposure scenario for some individuals
Some parent phthalates as well as their metabolites were excreted into sweat.”
The study concluded:
“Induced perspiration may be useful to facilitate elimination of some potentially toxic phthalate compounds including DEHP and MEHP. Sweat analysis may be helpful in establishing the existence of accrued DEHP in the human body.”
Sweating shown to be useful for elimination of BPA
BPA stands for bisphenol A — an industrial chemical that is used to make certain plastics and resins.
“In 16 of 20 participants, BPA was identified in sweat, even in some individuals with no BPA detected in their serum or urine samples.”
The study concluded that sweat analysis and induced sweating should be considered for analysis of BPA levels and its elimination:
“Biomonitoring of BPA through blood and/or urine testing may underestimate the total body burden of this potential toxicant. Sweat analysis should be considered as an additional method for monitoring bioaccumulation of BPA in humans. Induced sweating appears to be a potential method for elimination of BPA.”
Arsenic, cadmium, lead and mercury levels shown to be higher in sweat than urine or blood
This review focused on heavy metal excretion during induced perspiration and found that the concentration of toxic metals in sweat sometimes exceeded plasma or urine concentrations, and that arsenic and cadmium were especially concentrated in sweat.
“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.”
Note also how repeated sauna use brought mercury levels back to normal:
“Mercury levels normalized with repeated saunas in a case report. Sweating deserves consideration for toxic element detoxification.”
Sweating helps eliminate toxic trace metals
This study shows how sauna therapy was helped eliminate metals such as nickel, copper, zinc and lead.
“Sweating is a demonstrably significant route for excretion of trace metals, and sweating may play a role in trace-metal homeostasis. Essential trace metals could conceivably be depleted during prolonged exposure to heat; conversely, sauna bathing might provide a therapeutic method to increase elimination of toxic trace metals.”
Toxic elements preferentially excreted through sweat
This study again shows how certain toxins showed up in sweat that did not show up in blood or urine, therefore must have been stored in the body.
“Many toxic elements appeared to be preferentially excreted through sweat. Presumably stored in tissues, some toxic elements readily identified in the perspiration of some participants were not found in their serum. Induced sweating appears to be a potential method for elimination of many toxic elements from the human body.”
We can conclude from the scientific literature that induced sweating may be a very effective method to support the elimination of toxic trace metals and certain compounds. While not all compounds are effectively eliminated by sweat, it seems imperative to induce sweat daily as part of a well structured detox program, in order to support both the initial mobilization and the elimination of toxins from the body.
At Samahita, we provide a complimentary steam room to all guests every evening, and have two saunas, a full-spectrum infrared sauna plus a pure near infrared sauna, that guests can book, which are automatically included as part of our wellness programs.
