The science of the breath
Breathwork teacher, with Angelina Saunders · Australia
Levels of Longevity Map Shane explores
Shane Saunders is one of 100+ experts in the Live Beyond Project — a father & son quest for longevity.
Discover Live Beyond →Shane Saunders is a breathwork teacher on the Gold Coast of Australia who, with his partner Angelina Saunders, has spent years on a question most of us never ask: not how much we breathe, but how. Marek and Aleksander filmed a session with them in January 2024 — and where Angelina opens with awareness, Shane goes to the physiology.
His starting point is where breathing sits in the hierarchy of survival. You can go weeks without food, days without water — but only minutes without breath. That makes it the most fundamental of Longevity Basics, and the one we abuse most, because modern, high-stress life quietly teaches us to over-breathe.
The heart of Shane’s message is counter-intuitive: the magic isn’t in the big inhale, it’s in the pause — the small, natural space after you breathe out. That pause is where CO₂ rebalances, and CO₂ is what lets oxygen actually cross from your blood into your cells. Breathe too fast, blow off too much CO₂, and paradoxically less oxygen reaches the body. Learn to sit in the pause and the whole exchange becomes more efficient.
From there he goes further — into hormetic stress and altered states: circular breathing that drives CO₂ down on purpose, as a controlled dose, and can even reopen memory and emotion the body had learned to breathe around. Deep science, taught simply, and free to anyone with a few minutes a day.
We sat down with Shane and Angelina on the Gold Coast and did a breathwork session together. Angelina framed the awareness; Shane took us into the chemistry — why breathing less can give you more, and why that little pause after the exhale is doing more than the big dramatic breath. Of everything in Longevity Basics, the breath is the one I keep coming back to.
“Where it sits on the hierarchy of survival tells you everything. Weeks without food, days without water — minutes without breath.”
— Shane Saunders, Australia
“If the CO₂ levels don’t stay optimum in the body, then the oxygen in your blood can’t exchange out to where it’s supposed to be. It’s the pause after the exhale where that rebalances.”

Shane SaundersThere are two aspects to breathing: the mechanical — moving air in and out — and the chemical, which drives the energy in your mitochondria.
Shane SaundersCO₂ binds to the red blood cell, releases the oxygen, and vice versa. Without enough CO₂, the oxygen never gets out to the body.
Shane SaundersOur work is about discovering that little space in your breathing after you’ve breathed out — and learning to sit in the pause.
Shane SaundersThree ideas from Shane that change how you think about every breath.
After you breathe out there’s a small, natural space before the next breath. Stress, poor posture and dehydration make us snatch the next breath and crush that pause. Shane’s whole practice is learning to notice it and let it happen — because that pause is where CO₂ rebalances and the body settles.
“Learn to sit in the pause.”
Australia · from the interviewWe treat carbon dioxide as waste, but it’s the key to the exchange: CO₂ is what lets oxygen release from the blood into your cells. Over-breathe, blow off too much CO₂, and less oxygen actually reaches the body. Breathe slower, keep CO₂ optimal, and the whole system runs more efficiently — with less physical stress.
“Less CO₂, less oxygen where it’s needed.”
Australia · from the interviewFaster, circular breathing does the opposite on purpose — driving CO₂ down to create an altered state. Used deliberately, it’s hormetic: a small dose of the thing that, uncontrolled, is a panic attack. It can even reopen memory and emotion the body had learned to breathe around.
“Like cures like — it’s the dose.”

Shane Saunders was filmed with Angelina on the Gold Coast, January 2024. Passages from that conversation:
Shane Saunders“Coming back to why breathing matters — look at where it sits on the hierarchy of survival. Imagine how long you can go without food, then how long without water, then how long without breathing. There are varying amounts of time, but as a simple illustration: you can go a long time without food, a shorter time without water, and only a very short time without breath — before either your life ends, or some major damage happens in the body.”
Shane Saunders“What we’ve come to know is that there are two aspects to your breathing. There’s the mechanical — as you move air in and out of the body. And there’s the part we’ve become more interested in, because it’s the part that drives the chemical reaction that creates energy in the mitochondria. It supplies oxygen to the body and the brain, and it does it through the interchange of CO₂ and oxygen.”
Shane Saunders“Red blood cells are oxygenated cells. CO₂ binds to the cell, releases the oxygen, and vice versa. So every time you exhale, you’re getting this exchange — oxygen coming in, CO₂ going out. But if the CO₂ levels don’t stay at optimum, the oxygen in your blood can’t exchange out to where it’s supposed to be.”
Shane Saunders“With environmental stress, breathing dysfunction, postural problems, dehydration — that little pause in your breath is generally either not there naturally, or we’re psychologically suffocating it. We’re snatching the next breath, or forcing it. Our work is totally based around people discovering that there’s this little space in their breathing after they’ve naturally breathed out — and if you meditate on that space and allow it to happen, your CO₂ will naturally start balancing itself. It becomes a metaphor, too: sitting in the pause.”
Shane Saunders“When you get into altered states of consciousness through breathing — circular breathing — you’re changing the blood chemistry by lowering CO₂. Which happens to be the same breathing that occurs in a panic attack. It’s much like a homeopathic idea — like cures like — it’s the dose. It’s a hormetic stress. And those states can start accessing areas of the brain, like the hippocampus and memory, that you may naturally have shut down — if you’ve had a traumatic experience, the body often breathes in a way that keeps you from going there.”
