Train calm around air hunger.
CO₂ Control is advanced breath-control training: deliberately lighter, softer breathing and short, gentle pauses that build calm awareness around mild air hunger. These are training practices, not medical tests — they do not measure oxygen and they do not diagnose anything. Every practice here sits behind a safety check, and the rule inside each one is the same: keep it mild, and return to normal breathing anytime.
A curated pathway, not a catalogue. Each practice is short, guided by the orb, and gentle by design.
