CO₂-enriched water immersion raises skin oxygen levels significantly via the Bohr effect

Transcutaneous oxygen tension (tcPO₂) increased significantly to 72 ±3 mmHg during CO₂-enriched water immersion compared to a non-significant increase to 63.3 mmHg during fresh-water immersion, indicating improved oxygen delivery via the Bohr effect.

What this means for you

When dissolved CO₂ is absorbed through the skin, it signals your red blood cells to release more oxygen into surrounding tissue — a natural mechanism called the Bohr effect. In this finding, skin oxygen levels reached 72 mmHg during CO₂ immersion versus 63 mmHg in plain water. Better oxygen delivery to surface tissues supports circulation, recovery, and skin vitality.
