ORIGIN
A CO₂-based protocol for induced neuroplasticity. Developed from freediving physiology, contemplative training, and memory reconsolidation research. The method behind everything LJFC teaches.
The thesis.
Most breathwork methods use hyperventilation — rapid breathing that lowers CO₂, constricts blood vessels, reduces cerebral blood flow by 30–40%, and activates the sympathetic nervous system. This produces the “high” of Holotropic, Wim Hof, and similar modalities. Useful for catharsis. Limited for lasting change.
ORIGIN does the opposite. It uses controlled breath holds at partial lung capacity to mildly elevate CO₂ — a state called hypercapnia. This produces vasodilation, increases cerebral blood flow by 50–100%+, and shifts the autonomic nervous system toward parasympathetic dominance.
The result is a 30–90 minute window of enhanced neuroplasticity — a state where memory reconsolidation is possible, fear responses can be updated, and new patterns consolidate more efficiently than under baseline conditions. We didn't invent this window. We found a reliable, endogenous way to open it using the body's own CO₂ sensitivity.
The mechanism.
In 2009, Ziemann et al. published a landmark paper in Cell demonstrating that the amygdala functions as a chemosensor — detecting CO₂ through acid-sensing ion channels called ASIC1a. When CO₂ rises, pH drops, and these channels activate, triggering fear memory reconsolidation pathways.
Subsequent research by Taugher et al. (2021) confirmed that CO₂ exposure enhances fear memory consolidation when administered 1–4 hours post-learning — and that this depends on ASIC1a colocalization with NMDA receptors in amygdalar circuits. The effect is fear memory-specific.
Simultaneously, hypercapnia produces robust cerebral vasodilation. Bain et al. (2017) demonstrated that hypercapnia — not hypoxia — is the essential mechanism reducing cerebral oxidative metabolism during apnea. When hypercapnia was eliminated through hyperventilation, the metabolic reduction disappeared entirely.
The combined effect: a window of 30–90 minutes where memory consolidation is enhanced, defensive processing is reduced, and the brain is more receptive to pattern updating than at baseline. This is not a theory. It's a measurable neurobiological state with published mechanism research.
Amplifiers: nitric oxide, vagal activation, interoceptive focus
Nitric oxide (humming): Nasal humming increases NO production 15-fold. NO is a vasodilator and neurotransmitter precursor. It enhances the cerebral perfusion that CO₂ elevation already produces.
Vagal activation: Extended exhales and vocalization stimulate vagal efferents, shifting autonomic balance toward parasympathetic dominance before the CO₂ loading phase begins.
Interoceptive focus: Attention to internal sensation during the protocol. Enhanced bodily awareness correlates with improved emotional regulation — the mechanism through which the freediving skill of equalization becomes a training ground for metacognition.
The three elements.
Controlled breath holds build tolerance and activate the ASIC1a-mediated reconsolidation pathway. This is the piece that opens the neuroplastic window. The molecule that connects contemplative practice, freediving physiology, and memory reconsolidation research.
Strategic humming and nasal breathing techniques enhance oxygen delivery and neural plasticity, supporting the CO₂ work through vasodilation. Nasal humming increases NO production 15-fold (Weitzberg & Lundberg, 2002).
Pool and ocean-based training activates the mammalian dive reflex — the most powerful autonomic reflex in the human body. At depth: heart rate drops to 20–24 bpm, brain oxygen falls to 25–50%, but cerebral blood flow increases 93–165%. You don't need water for the transformation, but water accelerates the process.
The protocol.
Tap each phase to expand
Qi Gong-inspired movement — bouncing, swinging, shaking — to discharge stored tension and activate energy flow. Followed by nasal humming cycles to increase nitric oxide, and extended exhale patterns to activate vagal tone. The goal is to shift from sympathetic to parasympathetic dominance before CO₂ loading begins.
Progressive breath holds at 50–70% lung capacity. Each cycle: partial inhale → hold to moderate CO₂ urge → partial exhale → hold to moderate CO₂ urge → incomplete recovery breath. Typical session: 6–10 cycles. BOLT score guides intensity and progression. This is the core mechanism — controlled hypercapnia that activates ASIC1a channels and opens the neuroplastic window.
The window is open. Heightened receptivity, reduced amygdalar reactivity, enhanced consolidation. This is where the integration work happens — coaching dialogue, community sharing, somatic processing, skill acquisition, or water practice. The protocol doesn’t do the transformation. It opens the door. What you bring through the door is what changes.
Avoid high-stress activities during the consolidation period. Low-demand environment, light movement, minimal cognitive load. Memory consolidation research suggests this window is critical for durable encoding. The patterns you formed in the Origin State need time to set.

The lineage.
Before I ever held my breath underwater, I spent six months in Theravada Thai forest monasteries. In that tradition, practitioners establish a kammaṭṭhāna — literally “place of work” — a specific focal point that occupies the mind during meditation. Through daily conditioning, the practitioner builds a neuroplastic pathway between the cue and the desired state. They call the method upāya — skillful means.
When I found freediving — first with Stella Abbas in Tioman, then AIDA 3 with Pieter Van Veen in Dahab, then instructor training with Khaled El Gammal — I recognized the same process. The descent down the line mirrors the descent into meditation. Boyle's Law and the Transcendental Meditation consciousness diagram describe the same shape: compression deepens as you go down.
The ORIGIN protocol didn't come from a laboratory. It came from recognizing that contemplative traditions, freediving physiology, and memory reconsolidation research are all describing the same mechanism from different angles. CO₂ is the molecule that connects them.
What I call “state anchors” — cognitive cues that reliably trigger specific psychological states — are kammaṭṭhāna by another name. The language changes depending on who I'm talking to. The method doesn't.
The hypothesis.
Controlled CO₂ exposure during specific psychological states can accelerate belief restructuring and mental pattern dissolution. When we build CO₂ through breath holds, we create a controlled stress that opens neuroplasticity windows, challenges fear responses, enables rapid belief updating, and builds stress resilience.
We are tracking BOLT scores, anxiety scales, performance metrics, and subjective wellbeing across all participants. This is not a clinical trial. It's a systematic observation with the goal of generating hypotheses worthy of formal research.
The research partnership we're pursuing with UCSD — through the Ocean Human Performance Center — would formalize this. Longitudinal studies on a local population of trained freedivers who dive weekly at the same site, with pre-dive and post-dive assessment. The La Jolla Submarine Canyon provides the natural laboratory. The community provides the subjects. The protocol provides the intervention. The question is whether what we observe informally can be measured formally.
Safety
Absolute contraindications: Cardiovascular disease, uncontrolled hypertension, history of stroke or TIA, epilepsy, pregnancy, severe respiratory conditions, recent surgery, acute psychiatric crisis.
Protocol principles: No water during CO₂ loading phases — land-based only. No hyperventilation at any point. Graduated progression guided by BOLT score. Supine position only during CO₂ loading.
