Can sweating through aerobic exercise detoxify?

In fact, there is currently no evidence in the mainstream medical community to support the statement that "sweating through aerobic exercise can detoxify." The "detoxification" we often hear is originally a vague concept that is hyped by marketing. The body's metabolic waste excretion mainly depends on the liver, kidneys, digestive system, and urinary system. The waste that can be taken away by sweating does not even account for 1% of the total excretion.

I have been joining the gym for almost five years, and I have seen too many girls working out until they are dripping with water and still holding on, saying that they want to "force out the toxins from the body." Some people even buy sweat clothes and wrap themselves up tightly to run laps in the summer. A while ago, a member of a personal trainer did this. He fainted on the side of the track after running for 20 minutes. He was sent to the hospital to be diagnosed with low potassium and dehydration. The doctor turned over the test sheet and said that the urea in her sweat was less than the fraction of the urea she excreted in the toilet last time.

Of course, this does not mean that all relevant research completely denies the metabolic effect of sweating. Last year, I read a small sample study in the field of environmental medicine. It mentioned that people who have been exposed to environmental pollutants such as heavy metals and polychlorinated biphenyls for a long time do have higher toxin concentrations in sweat than in serum and urine. For this special group of people, active sweating can indeed help discharge some pollutants. However, ordinary office workers do not touch chemical raw materials or stay in environments with excessive heavy metals. There are not so many "toxins" that need to be excreted through sweating.

Many people say that their face is no longer oily and their whole body feels lighter after sweating after exercise. This is actually because exercise itself promotes circulation and the secretion of endorphins makes people feel naturally comfortable. In addition, sweat also removes the accumulated oil and old cuticles on the skin surface. It looks brighter and has nothing to do with "detoxification". If you really sweat deliberately for the so-called detoxification, it will easily destroy the skin barrier and cause folliculitis, eczema, and in severe cases, heat stroke and electrolyte imbalance. The gain is completely outweighed by the loss.
