Sweating and Detoxification

– Posted in: Natural Medicine
Sweating is important for detoxing

It’s often said that sweating helps the body ‘detox’.  This makes sense – the body is always working to rid itself of the byproducts of metabolism – thus we urinate and defecate to this end. However, you’ll never read anything in a physiology textbook about how the process of sweating also helps to remove toxic pollutants from the body – the main reason those of us with a focus on natural medicine encourage detox.

In traditional medical-physiological texts, sweating is only defined as a means of thermoregulation, or controlling body temperature. In this sense, when we sweat, it allows the skin to cool, thereby lowering body temperature.

Physiology texts teach that sweat is comprised of 99% water and the remaining 1% is a mixture of minerals like sodium, chloride, magnesium, potassium (electrolytes) and very small amounts of trace minerals like zinc, copper, iron, chromium and others. In addition, small amounts of true physiological waste products can be found in sweat as well and include the products of protein breakdown – ammonia, urea, and uric acid.  These waste products are also found in much larger amounts in urine, hence the kidneys bear the greater burden for removing them.

Mainstream medicine will deny that sweating is an important avenue for detox, let alone that detoxification is even a ‘real’ event, much the same way that environmental pollutants are usually neglected as a possible cause of ill health, and chemical prescriptions are the only answer to a patient’s symptoms.

Studies show that sweating plays an important role for detoxing.

Yet, we’re learning much more about the role sweat plays in true detoxification. Newer studies show that there is indeed much more to sweat than water, electrolytes and minor waste products of normal metabolism.

A study from the Archives of Environmental and Contamination Toxicology had this to say: “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 (blood). Induced sweating appears to be a potential method for elimination of many toxic elements from the human body.”

Another larger study found that in people with higher exposure to the widespread metal pollutants arsenic, cadmium, lead and mercury, higher levels were found in their sweat than in their blood or urine, and that removal of these toxins through sweating could meet or exceed excretion through urination.  In conclusion, the researchers state “Sweating deserves consideration for toxic element detoxification.”

Lastly, other studies have shown that two notorious toxic compounds, bisphenol A (BPA) and phthalates, are excreted through the sweat. BPA is used in the manufacture of common plastics like water bottles, CDs, sports equipment, in the lining of water pipes and beverage cans as well as in thermal paper used for sales receipts. (BPA has hormone-like properties and should be avoided.) Pthalates are another chemical used in plastics and are widely known as endocrine (hormone) disruptors, and linked to breast cancer.  BPA was found in the sweat of people who had none detected in their blood or urine, while phthalates were found in twice the amount in sweat compared to urine, and in some people it was detected only in their sweat and not in their urine.

Exercise plays an important role in helping a person to detox.

Knowing this, then it’s true that sweating can be considered an important method of detox.  As a doctor that focuses on wellness, I encourage all of my patients to exercise – for all the obvious health benefits – but also so they sweat. In order to be truly healthy, the body must get rid of wastes through all available channels – through defecation, urination, and sweat – which are often overlooked. (Exercise also causes the lymphatic system to circulate, which is another important, yet traditionally ignored aspect of circulation and immune system health).

Saunas and baths are great ways to get sweaty and detox.

Keep in mind you don’t have to exercise to sweat. Saunas and baths are also great ways to get sweaty and enhance the removal of toxins from the body. In fact many clinics that specialize in detoxification will have saunas or other similar modalities for patients to use as part of their therapy.

So, if you can’t sweat for some reason (you’re injured, it’s too cold outside) then try to get a sweat in a sauna or hot bath –we all know how much better we feel after a good sweat, and your body will have fewer toxins as well.
