Sweating & Detox: Can You Eliminate Lead?

Lead is absorbed into the body through the skin and eliminated through the sweat. To test this theory, researchers applied lead to the left arm of a participant. They then monitored the sweat from the right arm during the next few days. The data showed a marked spike in the amount of lead in the sweat. This proved both the absorption and elimination of lead through the sweat.

Does this raise a new possibility: Is it possible to remove lead from your system using the process of sweating?

The History of Sweating as a Health Practice

Over time, every culture around the world has recognized the potential for health-improvement through sweating. Whether through the Roman or Turkish bath, or a sweat lodge, or a sauna, people have always recognized the healing value of sweating. What does modern science have to say?

The 9/11 Rescue Workers Study

There is no study more interesting than the 9/11 study of sauna bathing, exercise, and supplement regimens on 9/11 rescue workers. The researchers looked at how many PCBs (polychlorinated biphenyls) were in the blood of the subjects. These PCBs are a type of toxic chemical found in many industrial products. The researchers measured the levels of PCBs in the blood of the subjects for a month prior to the initiation of the detoxification protocol. At that point, there had been no change in the levels of PCBs. After completing the detoxification program, the levels of PCBs in the blood of the subjects decreased and the subjects reported feeling better.

Although these results appear very encouraging, a close examination reveals some major concerns. First, the study was based on the results of only 7 of the approximately 400 subjects. Second, the detoxification program was developed by L. Ron Hubbard, the founder of Scientology. Therefore, it would be reasonable to assume that the study was biased. Third, the lead researcher appeared to have financial interests in the detoxification program. Fourth, the researcher did not disclose the details of the detoxification program.

The Role of Sweating in Heavy Metal Detox

For centuries, sweating has been used to treat mercury poisoning. As with much of medical history, however, there have been many questionable medical practices. Some examples include bloodletting and mercury-containing remedies, including mercurochrome. Can we rely on sweating as a safe and effective means of removing toxins from our systems?

A documented case study reports a person suffering from mercury poisoning recovered after six months of sweating and physical therapy. However, because there was no control group, it is impossible to determine if the sweating caused the recovery.

Scientific Evidence: Sauna Therapy and Lead Detoxification

One scientific study tested the effects of sauna therapy on the removal of lead from the body. Each subject participated in 2-6 sessions in a 200 degree Farenheit (93 C) dry sauna for 15 minutes. The researchers estimated that the subjects removed approximately 40 micrograms of lead per session through sweat, with some subjects losing over 100 micrograms of lead.

Therefore, this study indicates that a single sauna session may be able to help remove a large proportion of the lead absorbed through eating lead contaminated foods, such as bone broth. It is essential to conduct additional studies to confirm this finding. Specifically, additional research is required to determine the effects of sauna therapy on removing lead from the bodies of children. Children are at higher risk of lead poisoning than adults and generally produce less sweat. Additional information about sauna therapy and exercise can be found in the science behind sauna and exercise.

Can Exercise Help Remove Lead?

As previously discussed, if sweating removes lead from the body, is it possible to use exercise as a substitute for sauna therapy? A recent study analyzed changes in the levels of lead in the blood of athletes after an extended period of vigorous exercise. Surprisingly, an hour of endurance rowing resulted in a reduction of lead in the blood of the athletes by almost 12%.

On the other hand, a study analyzing the changes in lead levels in college basketball players after a single training session revealed that the levels of lead in the blood of the players increased by almost 300%. The researchers suspected that this result occurred due to the fact that the air contained high levels of lead, and therefore, the high levels of respiration during the training session increased the level of lead inhaled into the lungs.

The Bigger Picture: Prevention Over Detox

While sweating and dietary interventions may aid in eliminating lead from a person's body, they are not substitutes for initial prevention. The most effective way to address lead toxicity is by minimizing exposure. Interventions based on an individual's lifestyle should be used temporarily. However, continuous efforts must be made to remove lead from children's environments and to rid their environment of hazardous pollutants.

Conclusion

The science indicates that sweating, regardless of the method (heat or exercise), may aid in removing some amount of lead from a person's body; however, the degree of removal will vary with each individual and other factors, including environmental factors like poor air quality, can actually increase a person's exposure. Therefore, more research needs to be conducted to determine the full potential of sweating as a means of heavy metal detoxification.

Until then, while sweating may offer some benefits, the best plan for preventing heavy metal toxicity is to limit a person's exposure to toxic substances and promote cleaner environments. While detoxification has its merits, prevention is the best medicine.
