EWOT (Exercise With Oxygen Therapy) is breathing high-concentration oxygen — up to about 93% — through a mask while doing light exercise, usually for 15–20 minutes. Instead of the ~21% oxygen in normal air, you inhale far more during the window your body can use it best, to support energy, recovery and circulation.

EWOT stands for Exercise With Oxygen Therapy. It simply means exercising — a gentle treadmill walk or easy cycle — while breathing oxygen-enriched air from a reservoir bag through a mask.

Exercise raises your heart rate and opens up circulation, so more blood flows to your muscles and tissues. Breathing concentrated oxygen at that exact moment increases the oxygen delivered to those tissues — more than exercise or oxygen could achieve on their own. A 20-minute session is enough to feel it.

Yes. EWOT was pioneered by German physician Dr. Manfred von Ardenne in the 1970s, who studied how combining exercise with supplemental oxygen affected circulation and tissue oxygenation. It has been used as a wellness practice for decades. O3FY positions it honestly as a wellness protocol with reported benefits — not a medical cure.

An oxygen bar gives you a light whiff of oxygen at rest. HBOT delivers oxygen at rest inside a pressurised chamber for 60–90 minutes. EWOT is different: you breathe up to 93% oxygen while exercising, so your own boosted circulation carries it deeper — in just 15–20 active minutes.
