Heat, infrared and the body's response
Detoxification
In physiology, detoxification is the work of the liver and kidneys: chemically altering substances so they can be excreted in bile and urine.
Also called detox, detoxing, cleansing
The physiological meaning. In the liver, phase I reactions (largely cytochrome P450 enzymes) chemically modify a compound and phase II reactions conjugate it — glucuronidation, sulfation, glutathione conjugation — making it water-soluble enough to be excreted in bile or urine. The kidneys filter, secrete and excrete; the gut and lungs contribute. This is settled biochemistry with named enzymes and measurable rates.
How we describe it. The sauna is designed to support the body’s own detoxification rather than to perform it: heat, steam, a long sweat, and the liver and kidneys doing the chemistry they always do. Many clients notice residue on a white towel after a session. That is something people observe, not a measurement of what has left the body.
Why it matters here
Detox is the word most people arrive with. The straightforward answer is that the sauna supports the work your liver and kidneys already do, and that the mark clients notice on a white towel is something people observe rather than a measurement.
