The body can survive for days without water and weeks without food, but without the breath, it will die within minutes. The breath is closely connected with the heart, and its relationship with the nervous system is so direct that different responses are triggered depending on whether you are inhaling or exhaling. As those skilled in ancient contemplative practices have long known, the breath influences every part of the human experience.

Functional breathing often forms the missing link in terms of fitness and quality of life. It’s cost-effective and suitable for everyone. Despite this, breath training has nowhere near the same following as many mainstream diet and fitness trends. While most people will adapt other aspects of their lifestyle to promote better wellbeing, fitness or mental health, they often don’t think to adjust their breathing.

When focus is drawn to breathing, very few health and fitness professionals are trained to accurately identify dysfunctional breathing patterns and habits, or to give instructions that correct them. With the best of intention, they often lack the tools to help their clients learn practices consistent with physical and mental health. Instead of looking to the root cause of a problem, teaching is often symptom-led. It’s time to change this.

As awareness of functional breathing begins to gather pace in sport and in the wider community, this is the perfect time to gain practical, knowledge that will be relevant for you and your students for the rest of your life. Once certified, you will be able to apply your skills anywhere, any time, making a huge, quantifiable and immediate difference to your clients’ lives. And you will earn a great living in the process.


Every single person breathes, all day, every day. It’s fundamental to life. While it might make sense that elite athletes or people in high-pressure jobs could profit from some sort of extra breath training, surely it’s nonsense to suggest that breathing itself is the root cause of problems in the wider population?

The truth is, functional breathing training is relevant for everyone because:

  • Breathing pattern disorders affect 9.5 percent of the adult population. In people with asthma, its 29 percent, and 75 percent of people with anxiety have dysfunctional breathing (Jones et al., 2013/Thomas et al., 2001)
  • Most of what we know about breathing is wrong. For example we believe that oxygen is good and carbon dioxide is bad. The reality…
    CO2 is essential for good health and vital to oxygenation of the cells. Without carbon dioxide, the body would be starved of oxygen, whether or not oxygen was available in the blood (Singh, 2017)
  • We often urge our students to take a ‘deep breath’. But without an understanding of what a deep breath actually is and how to explain it, we may be inadvertently causing more harm than good
  • One of the most common breathing pattern disorders is something called chronic hyperventilation. Forget the image of someone puffing furiously into a paper bag – this is long-term over-breathing that causes imbalances in the blood chemistry and factors in many pathological conditions – read that again – poor breathing patterns are an underlying factor in a lot of illness
  • Chronic hyperventilation tends to involve fast, upper chest breathing. This triggers the sympathetic nervous system’s ‘fight or flight’ response leading to chronic stress (and many associated physical and mental health disorders)
  • Breathing should be through the nostrils, and rarely, if ever, through the mouth. Breathing through the mouth has been likened to trying to eat through your nose!
  • Slow breathing at six breaths per minute has been found to optimize heart rate variability (HRV), respiratory sinus arrhythmia RSA), baroreflex (blood pressure receptor) reflexes, gas exchange in the lungs, and to activate the calming power of the parasympathetic nervous system via the vagus nerve
  • Sleep disordered breathing is considered to be a public health epidemic, costing the economy millions of dollars in poor productivity and sick days, and contributing to road accidents and early mortality
  • Conditions including asthma, diabetes and epilepsy can often be successfully managed by increasing blood CO2 levels. In the case of epilepsy, hyperventilation has been proven to trigger seizures, and in panic disorder, blood CO2 levels are directly related to the panic threshold
  • Breathing exercises can help with problems as wide-ranging as performance anxiety, sleep, stress, poor digestion, heart health, hypertension and cognition
  • It is possible to maintain nasal breathing even during intensive exercise such as running. One study found athletes were able to train to 85 percent of VO2 max whilst breathing through the nose (Thomas et al., 2009)

Patrick McKeown BA, MA, is considered to be one of the foremost teachers of functional breathing. He has authored eight books, is published in 14 languages and has taught breathing for mind, body and sports since 2002. He has worked with more than 7,000 clients from children to elderly, from the most unwell to elite athletes. He has channeled a wealth of experience, expertise and passion into the delivery of this simple, easy to follow training, in order to share his approach with others, so that many more people can enjoy better health, performance and quality of life.

“When I was a young child, I suffered from asthma, tightness in my chest and constant wheezing. My nose was always congested, and so I learned to breathe through my mouth. This caused me to snore and sometimes even suffer sleep apnea at night. Things worsened during my teens and early twenties. I remember feeling tired all the time, and I struggled at school and university. No matter how hard I worked, my grades were only ever average. In 1994, I underwent nasal surgery, but there was no follow-up or information about how to restore nasal breathing, and so my breathing problems didn’t improve at all.

What I didn’t realize at the time was that my dysfunctional breathing was limiting the amount of oxygen that reached my brain on an ongoing basis. This caused me to experience tension, fatigue, stress and constant over-thinking. Eventually, my intake of asthma medication increased to the point that I ended up in hospital. I desperately needed help.

As luck would have it, in 1998 I chanced upon a newspaper article about the work of Dr. Konstantin Buteyko. His breathing method was fairly unknown at the time, but I do remember the newspaper piece contained instructions for an exercise to unblock the nose using a breath holding technique. I tried it, and it worked. In fact, it made such an impression that I made the switch to nasal breathing full time. I also made an effort to breathe more slowly, and to normalize my breathing volume. Within just a few days, I began to notice I had significantly more energy, my head felt clearer, my sleep was more restful, and I didn’t need to struggle to breathe. The changes I felt were so marked that I was inspired to find out more about the Buteyko Method, and to focus my new-found energy sharing it with other people. I received accreditation from Dr. Buteyko in 2002 and ever since then have worked with the breath, devising my own methods and applications in the Oxygen Advantage®.

Now in my mid forties, my health, focus and quality of life are unrecognizably better than they were in my teens. I’ve turned my entire life around simply by learning functional breathing techniques, and that’s why I am so passionate about teaching others to do the same.”


Based in Galway, Ireland, Patrick was educated at Trinity College Dublin and completed his clinical training in Russia in 2002. He is breathing adviser to Laird Hamilton’s XPT, Fellow of The Royal Society of Biology and published by international medical journals and leading book publishers. A TEDx …. Patrick’s work has… …touched the lives of thousands worldwide.

Patrick’s latest book, The Oxygen Advantage (published in fourteen languages), combines specially formulated techniques to reduce breathlessness during physical exercise, increase oxygen delivery to the brain, improve sleep and concentration, and retain focus under stress.
Patrick has worked with elite military Special Forces, SWAT, Olympic coaches and athletes, and with 173 trained instructors worldwide, Oxygen Advantage® is recognized as a foremost authority in breathing for exercise performance and sleep.

The Physiology of Breathing Explained (Nine Lessons and Exercises)

Physiology is the science of the mechanical, physical, and biochemical function of the body. It connects medicine, science and health, and provides parameters in which it becomes possible to understand how the human body adapts to stresses, physical activity and disease.

The physiology of breathing encompasses the role of breathing muscles (of which the diaphragm is primary), functional airways, blood chemistry and gas exchange with the atmosphere. When these aspects are fully understood, it is easy to adapt respiratory behaviors to voluntarily control the physiology – for example, reducing sensitivity to blood CO2 or altering levels of blood gases. In studying the physiology of breathing, you will learn about:

• How (and why) to influence the autonomic nervous system
• What Breathe Light really means and how it impacts the body
• Why breathing ‘hard’ causes poor oxygenation of the cells
• The importance of nasal breathing during both inspiration and expiration
• The effects of poor breathing patterns, long and short-term
• How to reduce breathlessness in sports
• The benefits of making the switch to nose breathing
• How to unblock the nose
• What the oxygen hemoglobin dissociation curve is and what it means for your students

The term ‘breathing exercises’ encompasses a vast array of potentially confusing practices. The exercises used in the Oxygen Advantage® are designed to work with the body’s physiology and biochemistry. You’ll learn a series of straightforward, safe, functional breathing exercises – the same exercises that Patrick uses with his clients every day. You will also discover how to apply the Body Oxygen Level Test – BOLT – a measure of functional breathing and an index of progress.

Functional Breathing Exercises (Ten Lessons)

1. Client assessment

Learn how to measure functional breathing using the BOLT score (Body Oxygen Level Test) and find out how to assess breathing patterns.

2. Basic exercises

Discover warm-up exercises and learn the Breathing Recovery Exercise.
In this lesson you will learn about nasal nitric oxide. Practical components include an exercise to calm the body and mind in times of stress, and an emergency exercise to help with asthma, panic attacks and hyperventilation

3. Restoring full-time nasal breathing

Learn an easy exercise to decongest the nose, and find out how to enable nasal breathing during rest, sleep and exercise. Explore how nasal breathing benefits people with hay fever, head cold and chronic nasal congestion

4. Breathe Light – Biochemistry

Reduced breathing exercises act like a meditation, anchoring the mind to the breath. In this lesson you will learn how to apply light breathing, and its many benefits, including:
Less breathlessness during physical exercise or exertion
Better oxygen uptake and delivery to the cells
More uptake of nasal nitric oxide
Lower sensitivity to blood carbon dioxide
Normalization of breathing volume
Better concentration and focus

5. Breathe Deep – Biomechanics

In this lesson you will learn about the different functions of the diaphragm and how it is essential for core strength, generating intra-abdominal pressure for postural control and spinal stabilization. Diaphragm breathing is a fundamental aspect of functional breathing.
Diaphragm breathing helps enable slow breathing
Diaphragm breathing helps calm the mind
It improves gas exchange as air is drawn deep into the lungs
It supports functional breathing for functional movement

6. Breathe Slow – Paced

A significant number of scientific studies focus on the therapeutic role of slow breathing, but the fact is, breathing too fast is a common habit symptomatic of dysfunctional breathing. Slow breathing doesn’t just apply to mindfulness or as an exercise; the breath can be trained so that everyday breathing is slower. This is important because slow breathing:
Optimizes ventilation
Improves breathing efficiency
Increases gas exchange in the lungs
Maximizes vagal tone
Maintains parasympathetic-sympathetic balance
Increases HRV (heart rate variability) and RSA (respiratory sinus arrhythmia)
Improves mental and physical resilience

7. Breathe Light, Slow, Deep

In this lesson, we bring all three dimensions of breathing together to build a complete picture of functional breathing.

8. Using a Breathing Belt

In this lesson you will learn about using the breathing belt as a support aid to breathe light, slow and deep. You will find out how to bring awareness to breathing patterns and improve the function of the diaphragm breathing muscle

9. Breathe Light Advanced

In this lesson you will learn more advanced techniques for breath reduction. Again, these exercises have a meditative quality, bringing the attention to the breath. These are important because they:
Enhance recovery
Improve functional breathing
Activate the diaphragm
Normalize breathing volume

10. Resistance training using SportsMask

Learn how to use inspiratory flow resistance to build strength in the respiratory muscles and overcome muscle fatigue during intensive exercise. This practice makes it possible to maintain light, slow and deep breathing during movement and reduce breathlessness during physical exercise.


This powerful approach combines functional breathing and the practice of mindfulness to improve oxygen delivery to the brain, and reduce worry and repetitive, unhelpful thoughts. How is this possible? One answer lies in the complex relationship between hyperventilation, levels of blood carbon dioxide and panic symptoms. Scientists have proven that while cognitive behavioral therapy is helpful in controlling anxiety, breathing has a direct impact on the abnormal blood biochemistry that is known to trigger panic attacks. In fact, breathing and cognitive therapy work on the body via different mechanisms, both of which support mental health (Meuret et al., 2010).

In this module you will learn how to acknowledge the activity of the mind, recognize the nature of thought, and embrace the present moment.

You will learn tools to teach gentle breathing and relaxation techniques to reduce invasive and negative thinking, and achieve clearer cognition. Your students will enjoy better concentration and control over their thoughts, as well as increased energy, happiness and appreciation for life.

Suitable for clients with anxiety, poor concentration, or depression, the simple instruction provided within this multimedia program can be used to overcome stress, panic attacks and attention-deficit disorders through easy-to-understand exercises and mindfulness. Students will experience noticeably lighter mood and more positive thoughts within seven days.
