Here’s Why

In August 2025, researchers at Brighton and Sussex Medical School published findings in PLOS One that confirmed what the Grof lineage had been observing for six decades: seven days of intensive breathing practices produced brain changes identical to those produced by psilocybin therapy. The same Default Mode Network deactivation. The same neuroplasticity window. The same experiential range.

No substances. No prescriptions. Just breathing – done correctly, with intention, in a container that can hold what surfaces.
This was not surprising to those of us working in this lineage. It was, however, the peer-reviewed confirmation that makes the conversation easier to have.

The Lineage Matters

My breathwork certification comes through direct transmission from a teacher who worked with Stanislav Grof for almost 20 years.

Grof was a Czech psychiatrist who conducted over 4,000 documented LSD-assisted therapy sessions at Johns Hopkins and the Maryland Psychiatric Research Center between 1956 and 1967 – serious research in serious institutions, before scheduling ended that chapter.

What those 4,000 sessions revealed was a map of the psyche significantly larger than the Freudian biographical model had accounted for. When LSD was criminalised, Grof spent years looking for a non-pharmacological method that could access the same territory. He found it. Accelerated breathing combined with evocative music could reliably produce non-ordinary states of consciousness equivalent in depth to what the sessions had produced.

This is not a technique borrowed from a book. It is a transmission lineage – handed from Grof to his certified facilitators, then to theirs. I am one generation removed from that direct transmission.

It means that when I sit with someone in a session, I am working from a cartography developed across 4,000 documented encounters with the deep psyche. Not a wellness framework. A map.

What is actually happening in your brain.

When you breathe connected and rhythmically for sixty minutes, three things happen in the brain that explain why participants often describe the experience as years of therapy in an hour.

The Default Mode Network quiets. The DMN is the brain’s inner critic – the network responsible for rumination, self-referential thinking, and the narrative loop of who you are and what you’re capable of. This is the same network deactivated by psychedelics. When it quiets, the subconscious material that it normally suppresses becomes accessible. What you have been managing at the level of thought surfaces at the level of felt experience, where it can actually be met.

Transient hypofrontality. Your prefrontal cortex – the analytical part that constantly evaluates, censors, and edits – temporarily softens. This creates access to emotional material and creative intelligence that the analytical mind normally overrides. The breakthroughs people spend years in therapy working toward can become reachable in a single window.

The neuroplasticity window opens. The combination of these two shifts creates a period of increased neural flexibility – a window in which patterns that have run your life for decades become genuinely amendable. This is where the integration work happens. This is why the post-session journal is not optional.

The session opens the material. The writing begins to metabolise it. These are two parts of the same process.

What is happening in the body.

The science here is well-documented.

During the first twenty minutes, connected breathing shifts blood CO₂ levels, raising blood pH toward alkalinity. This activates HIF-1α – a gene regulator involved in over 300 cellular repair processes. The body reads this as beneficial stress and begins mobilising repair mechanisms that chronic modern life keeps dormant.

Between twenty and forty minutes, the body begins producing its own chemistry. Human Growth Hormone surges. Beta-endorphins – the body’s natural analgesics – increase significantly. Studies document a 26% increase in circulating stem cells, the body’s cellular renovation crew. This is not relaxation. It is active cellular regeneration.

In the final phase, as breathing normalises, oxytocin and serotonin create what participants often describe as coming home to themselves. Blood tests confirm elevated oxytocin levels persisting 48 to 72 hours post-session. Heart Rate Variability – the most reliable available marker of nervous system health and stress resilience – improves by up to 40% immediately following a session.

For those dealing with chronic inflammation – and most people in sustained stress are – an 8-week diaphragmatic breathing study published in Frontiers in Psychology documented IL-6 reduction of 35 to 50%, comparable decreases in TNF-α, and measurable improvement in C-reactive protein. These are the inflammatory markers that drive aging, cardiovascular disease, and cognitive decline. Reducing them by 35 to 50% is not a minor effect.

What this has to do with the field guide work.

The breathwork in this body of work is not a relaxation practice. It is not stress management.
It is signal clearing.

The nervous system is the instrument through which you read the field – through which intuition arrives, decisions are made, and the broadcast signal is generated that the Law of Resonance says reality organises around. A dysregulated nervous system is a noisy instrument. You cannot read a signal accurately through noise. You cannot broadcast coherently from a body in survival mode.

The extended breathwork session is the fastest available route to the deep programs – the identity-layer material installed before you had language to evaluate it. The Default Mode Network deactivation creates a window in which shadow material, limiting beliefs, and the identity programs that are running the gap between what you want and what you have become directly accessible. Not as a concept. As a felt experience in the body.

This is why every satellite in the Field Guide system points toward breathwork as the integration accelerant. It is not an add-on. It is where the most profound work happens.

The Sessions

Private sessions are available in blocks. Each session is sixty minutes of extended breathwork followed by integration
The work is not for everyone and not for every moment. If you are in acute mental health crisis, recently medicated with certain classes of psychiatric drugs, or dealing with cardiovascular conditions that contraindicate controlled breathing, this is not the right entry point. We talk about that in the discovery call.

For those who are ready – who have done enough of the surface work to know that something deeper is required – the session creates a window the surface work cannot. What months of journaling can approach, an honest breathwork session can reach.

The call is thirty minutes. No pitch. You tell me where you are. I tell you whether and how this work is relevant to it.

The breathwork in this body of work draws from the lineage of Stanislav Grof without using the trademarked name Holotropic Breathwork®, which belongs to the Grof Transpersonal Training organisation. The distinction is strictly administrative.

**There are certain health and psychological conditions that preclude some individuals from participating in intensive breathwork practices. Please carefully check the list below.

For your safety, please do not participate if any of these conditions apply to you:

1. Under the age of 18 | Pregnant | Epilepsy | Detached Retina | Glaucoma | Severe PTSD
2. Aneurysms (if either you have had, or if more than one person in your immediate family (parents, siblings, children) has had one)
3. High Blood Pressure (that is not controlled with medications
4. Cardiovascular disease (and/or irregularities including prior heart attack)
5. Osteoporosis (that is serious enough whereby moving around actively could cause physical damage to your body)
6. Bipolar Disorder or Schizophrenia (a prior diagnosis by a health professional)
7. Hospitalization for any Psychiatric Condition (or serious emotional crisis in past 10 years such as an attempted suicide, nervous breakdown or psychotic break)
8. History of Strokes, Seizures or TIAs, or if you’re taking prescription blood thinning/ anti-clotting medications
9. Recent Head Injury (or other physical injuries that are not fully healed and could be re-injured through movement)

If you have asthma, you are welcome to breathe, but please have your inhaler available.

Neurodynamic Breathwork® (NDB) is intended as a personal growth experience and should not be looked upon as a substitute for psychotherapy.
