What is nervous system regulation?

Nervous system regulation is the ability to consciously shift between sympathetic (fight-or-flight) and parasympathetic (rest-and-recover) states. Through structured breathwork protocols, you can train your autonomic nervous system to respond to stress with control rather than reactivity.

How does breathwork improve performance?

Breathwork improves performance by increasing CO2 tolerance, enhancing vagal tone, and training the nervous system to maintain composure under pressure. This translates to better focus, faster recovery, improved sleep quality, and access to creative flow states.

What is CO2 tolerance training?

CO2 tolerance training involves controlled breath-hold exercises that gradually increase your body's comfort with elevated carbon dioxide levels. Higher CO2 tolerance reduces panic sensitivity, improves oxygen delivery via the Bohr effect, and builds resilience under physical and psychological pressure.

Who is the Poseidon Breath Method designed for?

The Poseidon Breath Method is designed for high performers including athletes, executives, creators, speakers, and professionals who want structured, science-backed nervous system training rather than generic wellness breathwork.

Can I do Poseidon Breath training online?

Yes. Poseidon Breath offers live online sessions via Zoom available worldwide, private 1-on-1 coaching sessions online, and a comprehensive online course launching soon. In-person sessions are available in Tulum, Mexico.
