Summary
Aaron Alexander of the Align Podcast interviews Patrick McKeown, author of The Oxygen Advantage, in a wide-ranging conversation that begins with a philosophical discussion about presence, materialism, and Western culture before diving deep into breathing science. Patrick shares his experience with Vipassana meditation and draws connections between mindfulness practice and functional breathing, arguing that both address the same fundamental issue of being present and connected rather than stuck in mental distraction. The breathing discussion covers the connection between breath and sleep: functional slow breathing calms the mind, improves oxygen delivery to the brain to reduce neural excitability, and enables deeper sleep. Patrick explains that nose breathing activates the diaphragm naturally, while mouth breathing drives upper-chest shallow breathing. He discusses the role of nitric oxide produced in the paranasal sinuses, which acts as a natural bronchodilator and sterilizer of incoming air, and how nasal breathing carries this gas into the lungs for improved ventilation-perfusion matching. The conversation also covers tongue posture and its relationship to airway development, how modern soft food diets have weakened jaw and tongue muscles compared to our ancestors, and the importance of nose breathing during exercise for improved recovery and performance. Patrick emphasizes that breathing properly should be as fundamental as eating and drinking well, yet it remains one of the most overlooked aspects of health optimization.
Key Points
- Nose breathing activates the diaphragm naturally while mouth breathing drives shallow upper-chest breathing
- Nitric oxide from paranasal sinuses acts as a natural bronchodilator and sterilizer of incoming air
- Functional slow breathing reduces neural excitability and promotes deeper sleep
- Tongue posture and resting position affect airway development and facial structure
- Modern soft food diets have weakened jaw and tongue muscles compared to ancestral diets
- Breathing is as fundamental to health as food and water yet remains the most overlooked
- The connection between breath and presence: following breath trains the brain to hold attention
- Nose breathing during exercise improves recovery time and performance despite initial discomfort
Key Moments
Breath connects sleep, anxiety and brain oxygenation
McKeown explains that good functional breathing and slow breathing calms the mind, improves oxygen delivery to the brain to reduce neural excitability, and enables deeper sleep -- while noting that many anxiety patients had tried every modality except addressing their dysfunctional breathing.
"as opposed to mouth breathing and fast, shallow breathing, which causes more shallow sleep. Lighter sleep, you're waking up more tired. So the breath, like, you know, people come in to me with anxiety and they come in to me with depression and panic disorder and they've been to cognitive behavioral therapy and they've been to many, many different modalities and the one thing that was often missing was the breath. And what they were often told was take this deep breath, which is entirely the wrong thing to be doing."
Mindfulness alone cannot fix dysfunctional breathing patterns
McKeown argues that while mindfulness and Vipassana are valuable, simply following the breath without changing it is insufficient for modern stressed populations who have developed breathing pattern disorders and need deliberate retraining to breathe through the nose, slowly, and lightly.
"if we're looking at Vipassana and the whole emphasis of mindfulness is follow your breathing, but don't change it. That's not enough. And the reason that it's not enough is because if you have breathing pattern disorders, you"
Carbon dioxide is the primary regulator of blood pH and oxygen release
McKeown explains that CO2 has been unfairly vilified as a waste gas when it is actually the primary regulator of blood pH and the catalyst for oxygen release from red blood cells, noting that the lungs hold far more CO2 than exists in the atmosphere -- and that even oxygen is toxic at high concentrations.
"Yes. Absolutely. Can we talk a little bit about it? Yeah, it's kind of strange, isn't it, that the one gas that's responsible for red blood cells releasing oxygen to the cells is considered as a waste gas. Got to get it out of there. Get it out. Take in as much oxygen as possible and get rid of as much carbon dioxide as possible. It's a waste gas. It's toxic."
