You have twenty-five thousand moments or possibilities each day to literally be inspired. We're all here to be inspired, but are we just breathing or are we really inspiring and being inspired?
Summary
- Oxygen evolved from a toxic gas to our primary energy source over 350 million years, showcasing the physical resilience inherent in the evolution of the human respiratory system. - Breath serves as a bridge between physical and sensory realms, altering blood chemistry and hormones to facilitate a deep connection with the internal universe, or microcosm. - Taking 25,000 breaths daily provides thousands of opportunities for literal inspiration during the inhale and conscious expression of energy during the exhale. - Synchronizing the rhythm of breath with others through physical contact builds safety and tribal connection by aligning heartbeats and individual energies. - Utilizing shared vocal vibrations and humming techniques connects the individual to the macrocosm, shifting collective energy to foster a sense of universal belonging.

Leigh Ewin’s Breathwork Session Turned A Biohacking Crowd Into A Tribe
At Biohacker Summit 2022 Amsterdam, “Micro And Macrocosm Connections Through Breath” Framed Breathing As Biology, Ritual And Collective Repair
In a conference culture often preoccupied with metrics, protocols and performance, Leigh Ewin offered something both simpler and more radical at Biohacker Summit 2022 Amsterdam: a return to the breath as the oldest technology of all.
His presentation, **“Micro And Macrocosm Connections Through Breath,”** delivered on Saturday, 15 October 2022 in Amsterdam, Netherlands, moved between physiology and philosophy, anatomy and intimacy. Ewin, a global coach in conscious breathwork known for guiding group sessions aimed at easing anxiety, pain and stress while improving performance, asked his audience to consider breathing not merely as survival, but as relationship.
“Microcosm and macrocosm literally mean the internal universe and the external universe, and through breathing, we connect with both,” Ewin said.
It was the kind of line that could have drifted into cliché in lesser hands. Instead, it became the organizing principle of the session. Breath, in Ewin’s telling, was both chemical event and existential bridge, linking blood cells to belonging, lungs to language, and the solitary body to the larger human field around it.
The Ancient Story Inside Every Inhale
Ewin grounded his talk in an evolutionary frame, reminding the audience that the respiratory system carried a history far older than any wellness trend. Oxygen, he noted, had not always been the body’s ally. Over immense stretches of time, life adapted to what was once hostile, turning a toxic atmospheric condition into the primary fuel of human existence.
That, he suggested, was resilience in its deepest form.
By invoking 350 million years of adaptation, Ewin did more than provide biological context. He placed the modern human breath inside an epic timeline, making each inhale feel less mundane and more inherited. The lungs, rib cage and intercostal muscles were not simply parts of the body. They were the architecture of survival.
The argument had a practical edge too. Breath, he said, alters blood chemistry and hormone production, influencing not only energy but emotion. In a summit devoted to optimization, Ewin’s point seemed to be that one of the most powerful regulatory tools available required no device at all.
Where Physiology Met What He Called “Magic Shit”
The talk’s most memorable turn came when Ewin described breath as “like an infinity loop,” a process at once autonomous and intentional, physical and sensory. The body pulled in air without asking permission. But awareness changed the quality of that exchange.
“Breathing is like an infinity loop. It is a physical, autonomous process, but when the physical and sensory elements converge, that is where the magic happens,” he said.
He gave that convergence a less polished phrase too, one that drew laughter and recognition from the room: “magic shit.”
It was a deliberately irreverent way of naming something difficult to quantify. Ewin compared it to a river meeting the sea, where sediments, nutrients and life forms gather in abundance. In the same way, he suggested, the richest dimension of breath emerged where mechanics met meaning, where oxygen entered not just tissue but awareness.
This was not an anti-scientific argument. It was, rather, an insistence that human experience exceeded the strictly measurable. Breath changed the body, yes. But it also changed the atmosphere between people.
Twenty-Five Thousand Chances To Be Inspired
Ewin turned next to language, using etymology to widen the conversation. Drawing on the Latin *spirare*, he linked breathing to spirit, inspiration and expression, recasting respiration as a daily practice of intention.
“Spirare means spirit and to enlighten; it means to breathe. Every time you breathe in, you are inspiring, and every time you exhale, you can choose how you want to express that energy,” he said.
The observation landed because it transformed repetition into opportunity. If, as Ewin noted, human beings take roughly 25,000 breaths a day, then the ordinary act of breathing became a cycle of continual possibility: inspiration on the inhale, expression on the exhale.
The idea was not framed as abstract spirituality. It was offered as a discipline of attention. Are we only breathing, Ewin asked in effect, or are we allowing breath to shape how we meet the world?
First, The Self
Like many effective facilitators, Ewin did not leave his talk at the level of concept. He moved the audience into practice.
He asked participants to sit upright, close their eyes and begin rhythmic nasal inhales followed by soft, passive releases, letting the air “fall out” rather than forcing it away. The technique was simple, but the simplicity was the point. Before anything communal, there had to be a return to one’s own body.
He described this as the oxygen-mask principle of breathwork: establish safety and connection with the self before trying to connect with anyone else.
In that sequence, Ewin’s work revealed one of its central concerns. Conscious breathing was not performance theatre. It was regulation. It was trust. It was a way of teaching the body that it could soften without collapsing.
Then, The Other
From there, the session expanded outward. Ewin invited audience members to turn to the person beside them, with permission, and embrace or, if preferred, hug themselves. The instruction was direct but careful, balancing vulnerability with consent.
Participants were encouraged to breathe together, slowly enough to feel one another’s rhythm and perhaps even each other’s heartbeat. The exercise, Ewin suggested, was a way of “hacking the ego,” loosening the rigid boundary between self and other through synchronized respiration.
It was an unusually tender moment for a biohacking conference. Yet it did not feel out of place. If much of the modern self-improvement industry is built around individual mastery, Ewin’s intervention proposed something different: that safety can be co-regulated, that calm can be shared, and that a deep breath taken with another person can be as powerful as one taken alone.
He described the best hugs as those accompanied by a joyful inhale and a soft exhale, the bodily signal that says: I am safe, it is good to see you, it is good to feel you here.
The Room As Instrument
The final movement of the session reached toward what Ewin called the macrocosm. Having guided the audience inward and then toward each other, he turned them toward the room itself and, symbolically, the wider universe beyond it.
Participants inhaled through the nose and exhaled with a closed-mouth hum, creating a collective vibration that spread across the venue. Hands on heart and belly, they repeated the cycle, filling the space with a low communal resonance.
The technique was simple humming, but Ewin presented it as an energetic intervention, a way of shifting the room’s emotional weather. In a literal sense, it was shared vibration. In a social sense, it was a rehearsal of belonging.
For a few minutes, the conference hall ceased to sound like a gathering of attendees and began to sound like a single organism.
Kindness As A Breathing Practice
Near the end, Ewin brought the session back to its ethical core. Breathwork, in his hands, was not merely about endurance, performance gains or nervous system control. It was also about how people treated themselves and each other.
“Remind yourself to be really kind, not only to other people, but to yourself. Everyone is doing the best they can,” he said.
It was a line that cut through the rhetoric of optimization with unusual gentleness. In a space where enhancement often dominates the conversation, Ewin’s emphasis on self-kindness felt almost countercultural.
He closed with a question rather than a prescription: “Take a moment to think about what you breathe for and who you breathe for. How will you breathe with others next time you see them?”
A Session That Asked More Than How To Breathe
At Biohacker Summit 2022 Amsterdam, Leigh Ewin’s “Micro And Macrocosm Connections Through Breath” did not present breathwork as novelty or spectacle. It framed it as inheritance, regulation, connection and choice.
The achievement of the session lay in how fluidly it moved across scales. It began with ancient oxygen and ended with human kindness. It moved from red blood cells to group humming, from the mechanics of the rib cage to the moral possibility of meeting one another more gently.
In that sense, Ewin’s core claim held. Breath linked the microcosm and the macrocosm not as metaphor alone, but as lived experience. Inside every inhale was a body. Inside every exhale was an offering. And for one afternoon in Amsterdam, a room full of biohackers was invited to remember that the most sophisticated system they had brought with them was already quietly at work, 25,000 times a day.
