We design conditions for people to operate well.
Breathing Flame works with physiology, environment and rhythm to help people recover capacity and respond differently to pressure.
Our Story
Breathing Flame was born from a simple observation: most high-functioning people are not broken. They are misconfigured.
I build environments that change how people operate.
Modern life places extraordinary demands on the human nervous system. Without deliberate recovery, regulation, and integration, performance eventually degrades.
We combine evidence-based physiological training with immersive environments to help people recalibrate how they operate.
The result is not a temporary breakthrough, but sustainable change that holds under pressure. Our work is rooted in Spain, with ongoing programs and private engagements in Málaga and Marbella, and select international locations.
Founder and Human Systems Architect
Oscar Trelles
Oscar Trelles is the founder and Human Systems Architect of Breathing Flame and author of The Human OS Manual. His work brings together experience in technology and organizational leadership with the study and practice of human performance, recovery, embodied learning and the environments in which behavior takes shape.
Breathing Flame is the applied expression of that work: defined experiences and learning interventions that help individuals and organizations examine how their operating conditions affect what they can do.
Breathing Flame emerged when that systems inquiry moved closer to the body. Breathwork, cold exposure, systemic facilitation, nervous-system regulation, recovery, and environment became part of the same applied question: what helps a person remain capable, adaptive, and coherent under real load?
The work is informed by the Human OS framework: a systems view of how physiology, environment, attention, behavior and recovery interact. The Human OS Manual gives the wider framework. Breathing Flame is one place where parts of that framework are practiced, facilitated, and integrated into real life.
