carbonic acid foot immersion raises tissue oxygen levels in people with poor circulation
CO2 foot immersion significantly increased transcutaneous oxygen pressure (tcPO2) from 56±14 mmHg to 63±15 mmHg (P<0.01) over 3 months in diabetic patients with critical limb ischemia, while tcPO2 remained unchanged in the control group (54±15 to 57±13 mmHg, P=0.81).
What this means for you
When oxygen delivery to your feet and lower limbs improves, tissues stay healthier, discomfort eases, and your body's natural repair processes get the fuel they need. This finding shows that CO2 absorbed through the skin can meaningfully raise the amount of oxygen reaching peripheral tissue — something most people notice as better warmth, sensation, and resilience in their extremities.
