What Is Exercise with Oxygen Therapy (EWOT)?

By Christine Ruggeri, CHHC

Do you know that breathing in higher levels of oxygen will work to improve the health of your blood, cells and microvessels? This is especially true when you use exercise with oxygen therapy to increase oxygen circulation throughout the body.

Exercising with oxygen therapy is a scientifically proven phenomenon that’s said to restore our natural health to a youthful state. This is called EWOT (exercise with oxygen therapy; pronounced e-watt), and it’s benefitting the lives of so many people.

It’s true that anyone can benefit from restoring his or her circulatory function and blood flow, but exercise with oxygen therapy is meant to increase oxygen circulation at a rapid pace. And although there’s certainly a time and place for hyperbaric oxygen therapy, for the everyday person who is looking to oxygenate blood in their body — thereby reducing inflammation, increasing energy and maintaining health — exercising with oxygen therapy may be more effective and efficient.


What Is Oxygen Therapy?

Exercise with oxygen therapy is when we breathe in higher concentrations of oxygen during exercise. In the past, EWOT utilized low-flow face masks or nasal cannulas that connected to oxygen generators. Oxygen generators are devices that take in room air, compress it and remove argon and nitrogen.

They are able to output 93 percent oxygen, which is more than three times the normal purity of room air. But these original devices only made up to 10 liters of oxygen per minute, which required much more time to see results. The latest developments in EWOT has cut the time to see noticeable results dramatically.

EWOT products have evolved and are now based on the 15-minute Quick Procedure and scientific research of Dr. Manfred von Ardenne, who wrote the Oxygen Bible (a 400-page book entitled Oxygen Multistep Therapy). In his book, von Ardenne uses over 500 medical references and offers scientific evidence based on 10,000 studies to support the use of oxygen to improve cellular health.

Dr. von Ardenne’s research suggests that a phenomenon occurs when you exercise with oxygen. It works to reduce inflammation and swelling of all microvessels in the body.

Imagine all of the pipes in your house have become narrow and can’t get enough water. Everything will eventually come to a screeching halt. That’s exactly what happens when our microvessels begin to narrow — the body isn’t able to get oxygen, blood and nutrients to the organ systems. This restriction causes pain and disease. This is where EWOT comes in.

Benefits of Exercise With Oxygen Therapy (EWOT)

There’s really no limit to the potential benefits of EWOT, but they are all possible because of three major factors: EWOT’s ability to improve oxygen circulation, restore blood flow and increase ATP production. Here’s a breakdown of these three major benefits of exercise with oxygen therapy and how they trickle down to influence overall health and wellness:


1. Increases Oxygen Circulation in the Body

Exercise with oxygen therapy gets oxygen into the arteries, veins and even the smallest capillaries that make up over 74 percent of your circulatory system. By increasing oxygen circulation in the body, your cells are getting the O2 that they need to process the millions of bio-chemical reactions they undergo every day.  The bottom line is that we can’t live without oxygen. And when our cells aren’t receiving enough oxygen on a daily basis, it will affect many aspects of our health.


2. Restores Blood Flow

All body processes require adequate blood flow, but stress and certain medical conditions can disrupt the blood’s ability to release oxygen into our tissues. We know that a decrease in oxygen supply to your blood can severely damage the function of your brain, liver and other organs. We need our blood to carry oxygen to our tissues in order for all body systems to work properly.

This is another major benefit of oxygen therapy. As oxygen circulation throughout the body increases, our oxygen-rich blood is able to send the O2 to our tissues, vessels and organs.

Restoring the flow of oxygen-rich blood also promotes the expansion of constricted capillaries. When our capillaries are deprived of oxygen, they begin to swell, thereby preventing further oxygenation. Oxygen therapy, particularly EWOT, reduces capillary swelling, enhances oxygenation and promotes circulation.

One of the most well-known benefits of oxygen therapy is its ability to improve cerebral blood flow. Research shows that hyperbaric oxygen therapy can be used to contribute to the healing of ischemic ulcerations in patients with diabetes. It’s hypothesized that this type of O2 therapy works to restore vascular activity, and affects the production of vasodilators and vasoconstrictors.


3. Increases the Production of ATP

When you exercise with oxygen therapy, you are allowing every cell to receive oxygen. This increases the production of ATP (adenosine triphosphate), which acts as a source of fuel within the cells.

Mr. Tebeau describes ATP as the “master healing molecule.” By increasing ATP, our blood cells separate so that they’re no longer sticking to each other and can therefore absorb more oxygen. When you make ATP at full capacity by giving the cells more oxygen, “the body can start healing as if we were in our teens,” says Tebeau. But when ATP levels are low, you cannot heal properly or quickly.

All other benefits of EWOT are downstream cascading effects of these three very important factors. Because exercise with oxygen therapy increases oxygen circulation, restores blood flow and increases the production of ATP, it may also benefit the body in the following ways:

  • Spikes immunity
  • Accelerates recovery from illness or injury
  • Boosts energy
  • Improves cardiovascular health
  • Supports lung function/respiratory system
  • Improve physical performance
  • Allows for faster recovery after workouts
  • Improves vision
  • Improves mental capacity/memory
  • Reduces inflammation
  • Assists in weight loss
  • Promotes detoxification

How to Use Oxygen Therapy

There are several products on the market today that serve as a source of oxygen therapy.  You can also receive oxygen therapy with a mask or nasal cannula that’s connected to an oxygen generator. The generator supplies oxygen that can be inhaled through a tube. However, there’s a problem with these devices because the most powerful oxygen generator can only produce 10 liters of oxygen per minute and we can easily breathe 50 liters or more per minute during exercise. We need far more oxygen during exercise than any generator can produce.


To solve the problem, today a large bag is first filled with 900 liters of oxygen using an oxygen generator. Once full, a non-rebreather high-flow mask connected to a large diameter hose is used to deliver an unlimited supply of oxygen to meet your needs during the 15-minute EWOT session. The generator is only used to fill the bag beforehand and once you begin exercising, you are only depending on the oxygen inside the bag.

You inhale from the bag and exhale CO2 into the room. The oxygen is HEPA filtered for purity as well. Just one 15-minute session can give you the great results.

Here’s what you’ll do using EWOT:

  • Exercise at least three days a week for 15-minute periods. This can be done with a stationary bike, treadmill, elliptical or with any type of exercise equipment that doesn’t require excessive head movement.
  • During the 15 minute session, sprint for about 30 seconds until your heart rate is at about 110 beats per minute (or 80 percent of maximum).
  • Then restore back to a normal exercise rhythm and heart rate for about three minutes.
  • Repeat the cycle again, 3–5 times, to increase vasodilation and open up the arteries so that oxygen gets into your oxygen-deprived tissues.

Because you are increasing your heart rate while breathing in oxygen, the O2 circulates within your body quickly. This significantly improves your results and requires less time than other sources of oxygen therapy.

Who is doing EWOT? Anybody can benefit from exercise with oxygen therapy — from top athletes to elderly patients with restricted blood flow. You can invest in your own EWOT system hat allows you to use oxygen therapy at home, or you can research nearby EWOT clinics that you can visit for your sessions.


Risks and Side Effects of Oxygen Therapy

When done correctly and for no more than 15 minutes at a time, there are almost no risks or side effects from EWOT. Breathing higher levels of oxygen is considered safe and there is no risk of oxygen toxicity.

For many patients who are just beginning EWOT, it’s the sudden change in their physical activity levels that can lead to side effects. For people who haven’t exercised in a long time and don’t have the physical stamina to endure a 15-minute session, it’s best to begin gradually and consult your doctor in advance.


Final Thoughts
  • Exercise with oxygen therapy is an efficient way to increase oxygen circulation throughout the body. EWOT causes your heart rate to increase. This allows you to make more carbon dioxide and forces more oxygen to your distal hypoxic tissues.
  • Research suggests that EWOT may help to increase oxygen circulation in the body, restore blood flow and increase the production of ATP.
