What is Exercising With Oxygen Therapy (EWOT)? How does it work?

What is Exercising With Oxygen Therapy (EWOT)? How does it work?

There are many fad methods to improve your health. But if we look towards science, we can find seemingly easy ways to help our body be stronger. Exercising With Oxygen Therapy, or EWOT, was developed with the basic understanding that without oxygen, we can’t function. But simply having some oxygen in our bodies is not enough. Instead, if we had access to better, more concentrated oxygen, we would be able to live stronger and longer.

We need oxygen to survive. While we can sometimes get by with the bare minimum of oxygen, if we want to exert more energy, then we will need more oxygen in our bodies. With EWOT, this all-important oxygen is transmitted into our bloodstream, allowing our muscles to work harder and our bodies to produce better results.

For the most part, the normal oxygen levels within our blood plasma are actually lower than they should be. This is often a result of lack of exercise or poor breathing techniques. If our oxygen levels are low, to begin with, then while exercising, these levels are depleted further.

The result of having oxygen-starved blood is that the cells can’t regulate themselves properly and instead start to absorb surrounding fluids. Too much fluid and the cells will swell. Blood cells reside within the capillaries of our body, which are small, narrow tubes. If the blood cells swell, then they take up too much room within the capillaries. This means that blood can’t flow as freely which then results in less blood moving around the body and less blood reaching muscles, tissues, and organs. Without blood, which is how oxygen is transported, then our body can’t function properly. In the long term, this can lead to a whole host of ailments. In the short term, during exercise, this can lead to shortness of breath, sore muscles, and an overall incapacity to achieve the desired results.


EWOT came to the forefront of science in the 1950s. It was discovered by German physicians who pioneered studies surrounding the important effects of oxygen. In particular, Dr. Manfred Von Ardenne looked at oxygen therapy which in turn has become EWOT. Since then, the principles of EWOT have remained very much the same. With modern science and technology, more has become known about oxygen therapy. And as more people have a better understanding of the basic science, EWOT has steadily been embraced by those in the health community.

There are many benefits to EWOT. Overall, you will become a more energetic person. Your entire body will have more access to oxygen will make you seem more alive and less sluggish. Organs and tissues will be able to heal themselves more easily because they will have the necessary building blocks needed. Our bodies take a lot of strain in the course of a lifetime. If they are better able to heal themselves and are healthier, to begin with, then they will have a much longer lifespan.

The immune system will get a much-needed boost. By improving your immune system before you get sick, it means that when you are exposed to new germs, your body will be better able to defend itself. Less sick time means more productivity.

As mentioned in the Science portion above, if blood cells don’t have enough oxygen, they take on fluid and become bloated, which then inflames blood vessels, muscles, and joints. Extra oxygen lessens this inflammation. If there is less pressure on the body, the internal organs don’t have to work as hard.


With EWOT, an individual needs direct access to concentrated oxygen. The air we breath primarily has oxygen in it, but it also has other gases. With EWOT, people use a container of special oxygen that is considered high concentration. This means that between 8 and 10 liters of oxygen flow from a tank into your body. Additionally, a special mask is required so that the pure oxygen does not escape. Most importantly, the oxygen saturation level needs to be between 90 and 95%.

There are many smaller canisters available with lower oxygen percentages and while they are more readily available, and at a lower cost, they will not achieve the same benefits. In fact, they are not truly considered a part of EWOT. Instead, the tank you need for EWOT must meet the specific requirements mentioned above for all the wonderful benefits to actually be received.

Before administering the concentrated oxygen, a person needs to begin some form of exercise. Stationary bikes are a good tool for this. Then, the oxygen is used, and a session lasts about 15 minutes. The number of sessions needed depends on the recommendation of a professional. It is highly recommended that you go to a specific EWOT clinic for the treatments. These professionals can explain the science behind the treatment and will be there to supervise you as you go through the process.

Exercising With Oxygen Therapy has been around for over 70 years, but thanks to new breakthroughs and a general understanding of science among most people, it is now growing in popularity. There is a recognition that our bodies are finite and it’s up to us to learn how to best use them. If we aren’t using our bodies to their fullest potential, then there must be a way to do so. EWOT allows us to build stronger organs, tissues, and muscles, help increase our immunity, and can lead to an overall feeling of energy and excitement.
