CO₂ Tolerance Method · Nervous System Self-Regulation · Neuroflexibility Training
Breathhold is the doorway. Behind it, a CO₂ tolerance method that teaches your nervous system to self-regulate, for mental stability and emotional resilience. Measured, not promised.
The Alchemy: Rewire method teaches you to reach peak-state cognitive performance, to self-regulate through stress and anxiety, and to downregulate for decompression and recovery at the end of the day.
The community
The method comes alive together. Every Sunday we breathe as one, live and free, no experience needed. Come experience it firsthand, meet the community, and feel for yourself that intensity isn't danger.
Join the Free Sunday ResetMost of the world still treats carbon dioxide as something to flush out. The CO₂ threshold is the baseline that switches on HRV, the brain maps and the neurochemistry of self-regulation. Raise your tolerance, and the system stops reading ordinary pressure as danger.

A 2023 pilot study with MuLabs in Lisbon, EEG and biomarkers. We cite it as exactly that: early, real, and ours.
Read the studyCO₂ tolerance is the core, the threshold that activates the rest. Live music and structured reintegration carry the work into coherence, then back into ordinary life.
The core. Safe, intermittent CO₂ tolerance trains the chemoreceptors that set your stress baseline, the threshold the nervous system reads to switch out of survival and into regulation.
Live sound played into the session, guiding the vagus nerve and central nervous system into coherence.
Vocal activation, nutrition and somatic work that carry the shift back into ordinary life, so coherence holds instead of fading.
The foundation. Master the core breath and mind-navigation techniques, and train your CO₂ tolerance from your baseline to a new normal, self-paced, at home.
14-day money-back guarantee. Your first session begins right after you start.
Compare all options →Every Sunday at 6pm CET, the Nervous System Reset, a live, guided CO₂ session. Breathe together with others, feel the method before you commit to anything. No experience needed.
You'll get the Zoom link and one reminder. Nothing else unless you ask.
“This practice allowed me to integrate within the present moment, to distill experiences from my past into a fuller form of understanding.”
James“I feel fortunate to have learned these lessons in this setting. It lets you integrate knowledge powerfully.”
Gustavo“Rodhø teaches at a very deep level. This truly accommodates the neurodivergent reality and offers something unique.”
