Breath Under Pressure — Executive Nervous System Training

What changes

What actually changes for your leaders.

These are leadership behaviors rather than wellbeing outcomes. Every one of them comes back to the same thing: a physical state you can learn to steady. And for every one, there is a number we can put against it at thirty days.

Outcome 01

Leaders who can actually listen

Being reactive is a physical state before it is a behavior, and it is the first thing to go when someone is carrying a lot. When a leader can steady themselves, they can listen without getting defensive, and they can take the half-second pause that makes a hard conversation go differently.

One manager's day-to-day variation accounts for around 30% of the swing in their own team's engagement.Barnes et al., Academy of Management Journal, 2015

Outcome 02

Clarity in the ninety seconds before you speak

There is a real difference between explaining a strategy and simply reading one out, and most of it is composure. The coherent breathing pattern I teach is quiet and completely invisible, so people use it at the table, mid-meeting, without anyone noticing.

Outcome 03

Real results and ROI

The quickest way to lose a room is to run a good session and then produce nothing afterwards. So I build you a report from the anonymous surveys and feedback taken at the retreat itself. Then, thirty days later, I follow up with every participant on a private call — to answer their questions, help them fit the practice into a normal working day, and make sure they are getting the results they came for.

The report is built from anonymous responses only, so nobody is ever identifiable to their employer. What you get back is the picture for the group.Yours to forward to whoever sets next year’s budget

Outcome 04

Stamina at the top

Functional breathing works on the twenty-three hours a day nobody is in a meeting: sleep, and how well someone recovers overnight. Over a year, that quietly sets the ceiling on what a leadership team has left to give.

Leaders who slept badly behaved more harshly the next day — and their employees' sleep then degraded in turn.Tariq et al., Journal of Sleep Research, 2020

The case

The people at the top are having the worst days.

This is the finding that tends to stop a leadership team in the room, because it inverts what everyone assumes. In Gallup's global data, leaders report meaningfully more stress, more anger, more sadness and more loneliness than the people who report to them — and are less likely to have laughed that day.

Which would be a private matter, except that it does not stay private.

Cost Of Poor Sleep

$411B

Estimated annual cost of insufficient sleep to the US economy — about 2.3% of GDP, and roughly 1.2 million working days a year.

Hafner et al., RAND Europe, 2016

A leader's state is not a personal matter

In a study tracking 88 supervisors across ten working days, 57% of the variation in how harshly a manager treated their team was variation within the same manager — the same person, better on some days than others. Poor sleep predicted the bad days. And how the manager behaved predicted their unit's work engagement, accounting for around 30% of the variance in it.

Barnes et al., Academy of Management Journal, 2015

And it travels

A separate study followed 101 supervisor–employee pairs across a working week. When a leader slept badly, they behaved more harshly the next day — and their employees then slept badly too. The loop closes. This is the mechanism by which one unregulated nervous system becomes an organizational cost, and it is the reason this work starts at the top of the structure rather than the bottom.

Tariq et al., Journal of Sleep Research, 2020

Mechanism

The science of breath shows real, measurable results.

This is respiratory and cardiovascular physiology, and it has been in the textbooks for decades. What is newer is that we now know it can be trained on purpose, and that most adults are running on a poor default without ever realizing it.

Exhale length sets the brake

Heart rate rises slightly on the inhale and falls on the exhale — respiratory sinus arrhythmia. Lengthening the exhale relative to the inhale increases parasympathetic tone. This is why a long exhale settles you and rapid shallow breathing does not.

Around six breaths a minute is a resonance

At roughly five to six breaths per minute, breathing rhythm and the baroreflex — the blood pressure control loop — fall into phase, and heart rate variability peaks. It is a mechanical resonance, not a belief, and it is why this specific cadence keeps recurring in the literature.

CO₂ is a signal, not just waste

Carbon dioxide is what lets haemoglobin release oxygen into tissue, and it is the primary driver of the urge to breathe. Chronic light overbreathing lowers CO₂ tolerance, so ordinary pressure starts to register as air hunger. Tolerance is trainable.

The one that lands hardest in a room of executives

Most people hold their breath at a screen without noticing. The CO₂ climbs, the body reads it as a genuine alarm, and it arrives in consciousness as unexplained afternoon dread.

There is a real mechanism behind this. A 2013 study found that patients with complete bilateral amygdala damage — including a woman who had reported no fear of anything for thirty years — had full panic attacks when they inhaled CO₂. Fear was not required. Blood chemistry was sufficient.

That reframes a great deal of what gets called stress. Some of it is not appraisal of your circumstances at all — it is a chemoreceptive alarm responding to how you have been breathing for the last four hours.

Feinstein et al., Nature Neuroscience, 2013

Sixty seconds — do it now

Try it now. It takes about a minute.

This is coherent breathing — five and a half seconds in, five and a half out. It is the most studied pattern in the field, and it is the one your team would leave holding.

Follow the trace. Nose if you can, quiet, low into the belly. Most people feel something inside four or five cycles — not relaxation in the vague sense, but the baroreflex bringing heart rate and breath into phase, which shows up on any HRV monitor as an immediate, visible change.

Nobody watching would know you were doing it, which is rather the point. The practice an executive will actually use before a board meeting is the one nobody can see.

Method

Three practices, and when to use each one.

Most breathwork fails inside companies because a room gets one big experience and then no idea what to do on Tuesday morning. I teach three separate practices and attach each one to the moment it is actually for.

Baseline

Functional

Focuses on nasal, diaphragmatic, light, slow and deep breathing, and on improving your CO₂ tolerance. That matters most during sleep, when breathing problems usually go unnoticed.

When: your day-to-day breath
Supports: sleep quality, recovery and resting physiological load
Timescale: anywhere from immediately to weeks or months

On demand

Coherent

The practice we shared further up this page. Roughly 5.5 seconds in, 5.5 seconds out. Deliberate, portable, and completely invisible to anyone watching, which is precisely why an executive will actually use it. No cushion, no app, no closed eyes.

Supports: composure, HRV and clarity under load
Timescale: immediate

Opt-in · screened

Active

This practice replicates life. It overwhelms and stimulates through quick breathing that loads the system, then guides you back down into a calm, balanced state. It is a journey the room tends to remember — not the science of it, but how it felt.

When: once a week or once a month, with a facilitator present
Supports: relieving accumulated stress, shifting patterns and perspective
Timescale: session-based

One is how you breathe when you are not thinking about it. One is what you do ninety seconds before you speak. One is what you can only do with a facilitator and a floor.

Most of the corporate work uses only the first two. They are gentle, they suit almost everyone, and they are where the strongest evidence sits. The third one is powerful and it is usually what people remember, which is why I run it at a retreat with a floor and a screening form rather than slotting it into an afternoon agenda.

Evidence

What the research actually found.

Every row here is a peer-reviewed study you can pull up before the meeting ends. I have listed the sample sizes and the study designs so you can weigh them yourself.

Heart rate variability biofeedback — training people to breathe at their own resonance rate — produced a large effect on stress and anxiety. Hedges' g = 0.83.

Goessl, Curtiss & Hofmann, Psychological Medicine, 2017

Meta-analysis · 24 studies · n=484

Korkmaz et al., JAMA Network Open, 2024

Randomized, active control · n=129 · per-protocol

Five minutes a day of structured breathing improved daily mood and lowered resting respiratory rate more than an equivalent daily dose of mindfulness meditation.

The program

Corporate breathwork, built for executives.

My in-person session format is purpose-built for a leadership offsite: 90 minutes, 8–25 people, a short evidence frame, a measured live demonstration, and one protocol the team leaves holding. I connect with each participant before and after so the room watches its own numbers move, and everyone leaves with a one-page protocol card.

Executives run in a near-constant state of high alert. Deadlines, decisions and pressure keep the nervous system locked in fight-or-flight, and over time that drains focus, patience and performance — and pushes people towards burnout. What I teach is a practical, science-backed way to regulate that response on demand, using nothing but the breath.

There are two halves to it. A simple daily practice that rebalances the nervous system, and a guided experience of what that regulation actually feels like, so people know what they are working towards.

Part 01 · The foundation

Breathing awareness and functional breath

Before anything else I teach people how to breathe well in ordinary life. Most of us default to shallow, fast, mouth-based breathing without ever noticing, which keeps the body mildly stressed even when nothing is wrong. The fix is functional breath: nasal, diaphragmatic, light, slow and deep. It becomes the pattern people carry into meetings, commutes and downtime, not just into a formal practice.

Part 02 · The daily practice

Coherence breathing, 5.5 minutes a day

On top of that sits a specific technique with good science behind it: a 5.5-second inhale paired with a 5.5-second exhale, held for 5.5 minutes a day. That pacing brings heart rate variability into a coherent rhythm and helps balance the autonomic nervous system. It is short enough to fit into any day, and it is the daily repetition that lets it compound and genuinely change how someone responds to pressure.

Part 03 · The experience

A 45-minute active breathwork journey

The second half is a guided 45-minute session built to mirror the arc of a high-stress day. It deliberately moves people through the same activation and pressure they feel at work, then walks them back down through calm, into peace, and finally into balance. The point is not relaxation. It is giving people a felt reference point for what leaving fight-or-flight is actually like, so the daily practice has something concrete to aim at.

Why this matters for a leadership team

Framed for a corporate audience this is not a wellness add-on, it is a resilience tool. Executives who can reliably bring their nervous system back to baseline are less likely to get stuck in chronic stress, better able to think clearly under pressure, and less prone to the burnout that erodes both performance and retention. A few minutes a day, reinforced by a deeper session now and then, changes how leaders function under load.

How I measure the impact

There is a simple loop behind it. Participants complete a survey at the start, and I check in again thirty days later on a private call. That follow-up looks at whether people have actually kept up the daily practice, whether they notice a real shift in how they handle stress, and what they think it has done for their productivity. It turns the program from an anecdote into a before-and-after you can share back with the organization.

Facilitator

I am not a management consultant and I have never pretended to be one. I have spent fifteen years on a single subject: how people breathe, and what changes when they learn to do it on purpose.

I came to it the hard way. A serious car accident in 2001 left me rebuilding a body that no longer worked the way it used to. What started as rehabilitation turned into years of study across breath, movement and the nervous system, and eventually into this practice.

In a room of executives I am the outside specialist, and I think that is the right role. I am not there to have an opinion on your strategy. I am there to teach a physical skill properly, to a standard, to people who are used to being very good at things.

Never experienced complex concepts presented in such a palatable way. A naturally born instructor of everything she sets out to teach.

— Jim T.

She taught me to calm my nervous system and recognize my protective patterns — calmer and less reactive, so I'm no longer knocked over by the pressures of life.

— Regan W.

Her ability to hold a room with both compassion and strength is remarkable. I always felt seen, heard and understood.

— Jack, breathwork facilitator

Common questions

The questions I usually get.

Half my leadership team will think this is nonsense.

Good — skeptics make the best case for this, because the effect is measurable rather than a matter of belief. The session opens with physiology and citations, not intention-setting. Nobody is asked to share feelings, chant, or disclose anything personal. The most common outcome with a resistant room is that the loudest skeptic becomes the strongest advocate, because they went in looking for the mechanism and found one.

What if someone doesn't want to participate?

They observe. It is stated explicitly at the start that opting out is fine and carries no comment. Coercion in a room of direct reports would undermine the entire premise — the work is about voluntary self-regulation. In practice, observers usually join within twenty minutes.

Is this safe? Who shouldn't do it?

The two protocols used in a corporate session — coherent and functional breathing — are gentle and suit essentially everyone. The more intense active work is opt-in and screened beforehand via a confidential form, so nobody discloses anything in front of colleagues. Donna carries professional and general liability insurance and can meet standard vendor requirements.

How is this different from the meditation app we already pay for?

Adherence and specificity. App engagement collapses within weeks, and a generic relaxation track is not attached to any moment in a working day. This teaches three distinct protocols, each tied to a specific use — one for sleep and baseline, one for the ninety seconds before you speak, one for facilitated depth — taught in a cohort, in person, with measurement. It complements an app; it does not compete with one.

What do we actually get, as a deliverable?

Participants leave with three practices they can run unaided for the rest of their lives, and a one-page protocol card. The sponsor receives a cohort-level report comparing pre and post measures on validated instruments, with no individual identifiable. For the six-week program that report is the artefact you forward to whoever controls next year's budget.

Do you carry insurance, and can you meet our vendor requirements?

Professional and general liability insurance, W-9, certificates of insurance naming your entity as additional insured, and a standard participant waiver are available on request, along with references. Screening forms are handled directly with participants, so no health information reaches the employer at any point.

What do you need from us on the day?

A room where people can lie down for the active work — floor space, ideally carpeted, with mats or blankets. Somewhere quiet. Ninety minutes without interruption, ideally not immediately after a heavy lunch. Phones out of the room. No technology or AV required beyond a way to be heard.

Next step

I bring real, tangible results to even the most hardened corporate skeptics.

My programs are backed by real science, not wellness fluff. If you want to test that properly, put your most skeptical people in the room for the demonstration — in my experience they end up making the best case for it.

Three steps, in order. First a short briefing with whoever owns the outcome. Then the session itself at your offsite, with the survey built into the day. Then the thirty-day follow-up calls and the report you can carry into next year's planning.
