CO₂ absorbed through skin drives physiological responses independent of water temperature
The physiological effects of CO₂ bathing are specifically produced by the chemical substance CO₂ itself, not by water temperature or other bathing factors.
What this means for you
This means the benefits you feel from CO₂ immersion come from the gas itself interacting with your body — not just from soaking in warm water. Your skin absorbs CO₂ directly, triggering real circulatory and cellular responses that plain warm baths simply don't produce.
