How Detox Works in the Body

Your liver and kidneys are the primary organs charged with filtering and removing waste. Your skin, through sweating, plays a smaller—but measurable—supporting role. As a result, infrared saunas aren't replacing internal detox systems but may enhance sweat-based excretion of substances like heavy metals, albeit in small amounts.

Infrared vs Traditional Saunas: What's the Difference?

Traditional saunas heat the air around you—even up to 200 °F—while infrared saunas use radiant heat, warming your body directly at lower temps (113–140 °F). This allows deeper penetration, potentially boosting sweat output in a more comfortable way.

Scientific Evidence on Toxin Elimination

Heavy Metals & Elements

• Studies show that arsenic, cadmium, lead, mercury, cobalt, aluminum, and others appear in sweat at levels equal to or higher than urine.

• Example: Cadmium appeared in 80% of sweat samples even when absent in blood or urine. Mercury was detected exclusively in sweat for some individuals.

Chemicals & Metabolites

Sweat following infrared sessions has shown traces of phthalates, BPA, flame retardants, and pesticides—implying that IR sessions may help eliminate some environmental pollutants.

Limitations of Current Research

The evidence is promising but remains preliminary. Most studies are small, with limited sample sizes. More high-quality research is needed.

Expert & Skeptic Perspectives

• Supporters acknowledge the ability to reduce toxic burden through sweat, especially with heavy metals.

• Skeptics argue the detox role is overstated—since the liver and kidneys handle the majority of detoxification.
