My background as a polar sailor, sports educator, sophrologist combined with an equal passion for the sea and human potential naturally led me to work in athletes mental training. It was another ocean explorer, multi holder of world records in freediving, who first told me about Patrick McKeown. This encounter with the OxygenAdvantage method was revealing… Because I realized that my breathing wasn’t quite functional despite a sporting life spent outdoors and the interest I had in breathing. Functional breathing has allowed me to overcome recurrent sinusitis since early childhood. I literally discovered a form of comfort in breathing that I had never experienced before. It hasn’t stopped me from accomplishing great projects and making beautiful polar sailing expeditions but it’s much better now and there is no doubt that my energy would have been even better if I had discovered the OA method earlier.

Breathing is a vital function that affects each of us, you don’t have to be athletic to worry about whether our breathing is functional or not.

There is a strong link between functional breathing and physical and mental health.

The OxygenAdvantage method allows to:
– improve its overall shape
– Reduce shortness of breath
– Relieve symptoms of many common functional disorders (Asthma, sleep apnea, anxiety, panic attack)
– Improve attention and concentration.

Oxygen Advantage® Invincible Breathing is a natural method of breathing that helps meet the challenges of everyday life through the transformative power of breathing™, giving the tools to breathe easily.

and about scientific facts.

I am teaching the OA method online and face-to-face, in French and English.

My practice is located in Sommarøy, Tromsø, but video consultations allow me to break the distances. Don’t hesitate to get in touch. 🙂

“Oxygen Advantage” group classes will be planned soon in face to face or online (program to come).

Did you know that the way you breathe every day has an impact on how you feel? Poor breathing mechanics affect movement. The risk of injury increases and you tire more quickly. The supply of oxygen decreases, and in the long run, your health suffers. But as you breathe, all day, every day, it can be hard to recognize that you could improve your breathing, even when there’s an obvious problem like asthma. The advice to “breathe deeply”, given by everyone, can unfortunately exacerbate dysfunctional breathing. Recent discoveries have allowed us to understand that we need to change the “respiratory software” even though the work of the Danish doctor Kristian Bohr (Bohr effect) dates back to 1904…


“A breathing pattern disorder, or dysfunctional breathing, is a situation in which breathing is problematic and produces symptoms such as shortness of breath. It manifests as a psychological or physiological habit, such as breathing too deeply, breathing too fast (both symptoms of hyperventilation), breathing with the upper chest at rest, or breathing irregularly with frequent apneas or sighing. Respiratory disorders affect 9.5% of the adult population studied, rising to 29% in people with asthma and 75% in people with anxiety. These numbers are not surprising, given that asthma, anxiety, panic attacks, and stress all negatively influence breathing patterns, creating a vicious cycle of inefficient breathing”.
Extract “The Breathing Cure”, by Patrick McKeown (Oxygen Advantage)


– Symptoms that have no obvious organic cause
– Gas or early fatigue during exercise
– Rapid and noisy chest breathing
– Below-normal levels of CO2 in the blood.
– Feeling like you never have enough air, or regularly having cold hands and feet, or feelings of panic and anxiety
– Sleep-disordered breathing, including snoring or sleep apnea.
– Difficult awakenings with feelings of exhaustion.
– Frequent or chronic back or neck pain, or repetitive strain injuries.

All of these symptoms can indicate chronic hyperventilation, which means habitually breathing more air than the body demands. Hyperventilation is often related to mouth, thoracic, rapid, sparse breathing.

In the long term, this can contribute to the onset of heart disease, high blood pressure, and early mortality. We see that the instruction to “breathe deeply”, which often translates into a quick inhale, can be detrimental.

A sedentary lifestyle, with little physical exercise, can impact the way the body processes oxygen.


We know that dysfunctional breathing often involves mouthing, chest breathing, rapid breathing, and shallow breathing

Functional breathing is nasal, slow, abdominal, 24/7 and 7/7


The nose is the organ of breathing. It filters and warms the air inhaled. It helps to stay hydrated on the exhale. It sterilizes the inhaled air, to eliminate bacteria, viruses and allergens before they reach the lungs.
The mouth has no function in the respiratory system, except that it forms an escape route for air if the nose is blocked or when the exercise is so intensive that it requires breathing a much larger volume of air.
Typically, nasal breathing is much better. For example, for those with exercise-induced asthma, mouth breathing may be part of the problem. Open-mouth breathing brings cold, dry air directly into the lungs. This dehydrates and inflames the airways, causing bronchoconstriction that promotes susceptibility to infection.

Nasal breathing adds greater resistance. It slows down breathing, relieving stress. It also puts a strain on the diaphragm. When the diaphragm is functioning properly, lung volume increases.
Nasal breathing also reduces sleep apnea. Scientists have proven that when breathing is done with your mouth open, the symptoms of sleep apnea are much greater.
