carbonic acid skin exposure increases leg blood flow and oxygen delivery to the feet
Transcutaneous CO2 exposure for 20 minutes significantly increased femoral blood flow, tibial pressure, and foot transcutaneous oxygen tension in patients with stage II lower limb arteriopathy without systemic hemodynamic changes.
What this means for you
When circulation in the lower legs improves, more oxygen reaches the feet and peripheral tissues — something many people notice as reduced heaviness, better warmth, and improved sensation in the legs. This response happened locally, without affecting overall blood pressure or heart rate, suggesting a targeted circulatory effect.
