Does Heat Exposure Help You Detox?

Hot exposure has distinct mechanisms that can aid in detoxification and improve various aspects of health.


Hot exposure, particularly through sauna and banya use, assists in detoxification by promoting sweating.

Sweating has been shown to facilitate the elimination of heavy metals like arsenic, cadmium, lead, and mercury, as well as other toxins such as PCBs and BPA. The concentration of these toxins can be up to 10 times higher in sweat than in blood, highlighting the effectiveness of saunas in eliminating harmful substances from the body.1


Sauna use has been linked to improvements in cardiovascular health, hormonal balance, reduced risk of dementia, and even potential protection against certain toxins. Sweating also boosts glutathione production, an important detoxifier.1
