Oxygen Advantage

What if oxygen and carbon dioxide are only part of the story? Nitric oxide expert Dr. Nathan Bryan joins Patrick McKeown face to face in Houston to explore the “third gas” in every breath, and why it’s essential for blood flow, oxygen delivery and performance. They cover the kind of exercise that boosts nitric oxide, nasal breathing and mouth taping during training, nitric oxide vs carbon dioxide, and the 5am routine Dr. Nathan Bryan never skips. They also discuss blood pressure, the oral microbiome and why nitric oxide declines with age.

Patrick McKeown sits down with Bob van de Gronde, director of Air Hunger – The Breathwork Movie, now streaming worldwide. The film takes breathing out of the wellness corner and into performance, following elite athletes, military veterans, scientists and everyday people. A conversation about putting breathing on screen, and why it might be the most underrated lever we have.

Patrick McKeown sits down with Dr. Tim Hughes, an anaesthetist, advanced breathwork instructor, and co-founder of The Breath Doctors. Tim uses breathing to calm patients before surgery and himself before he walks through the hospital doors. A conversation about performing under real pressure—and how something as simple as breath can be the difference.

Patrick McKeown and James Nestor meet face-to-face for the first time to discuss the science of breathing, functional breathing methods, and how nasal breathing transforms sleep, health, and well-being.
After years of correspondence—Zoom calls, Instagram Lives, emails, voice notes—they finally sit down together. What was meant to be one episode ran long. They kept talking well into dinner.

What if the key to running further, calmer, and healthier wasn't in your legs — but in your nose?
In this episode, Patrick McKeown sits down with Dr. Bill Hang: orthodontist, airway pioneer, and marathon runner approaching his 80th birthday.
After hearing Patrick speak 15 years ago, Bill made two decisions that changed his life — taping his mouth at night and running with his lips sealed.
He's since run the Boston Marathon multiple times breathing entirely through his nose, including once with his mouth taped the whole way.
But this conversation goes far beyond running. Dr. Hang shares why he walked away from traditional extraction orthodontics, how forward jaw development can transform a child's airway, and what every parent should know before agreeing to have their child's teeth removed.
