Breathing sits in an unusual place in human physiology: it runs automatically, but you can take manual control of it whenever you choose. That makes it the most accessible tool a pilot has for changing their own state — no equipment, no cost, legal at every phase of flight. This episode teaches three practices: the physiological sigh for a fast reset after a startle, coherent breathing for building resilience, and the triangle breath for downshifting at the end of a duty day.
On The Calm Cockpit Podcast‘s Season 2, Episode 13 (June 24, 2026), hosts Gita Brown — a yoga and meditation educator with 30-plus years teaching high performers, and a midlife student pilot — and John Niehaus, a corporate pilot and flight instructor, work through the mechanics and then practice each technique on air.
One thing to know before the techniques, because it shapes everything else.
The Point Is the Attention, Not the Technique
Brown’s repeated thesis is that the specific practice matters far less than most people assume. What matters is that you are paying attention to your breath at all. She strips away performance expectations at every turn: there is no target mental state, you are not required to feel relaxed, and if a session leaves you feeling nothing in particular, you still practiced.
She also pushes back hard on the most common advice in the world — telling a stressed person to just take a deep breath. It tends to land the same way as telling someone to calm down, particularly when they are angry and the anger feels protective.
Her framing for expectations is what she calls the rule of thirds: roughly a third of your sessions will feel great, a third will feel lousy, and a third will feel like nothing much. All three count.
It’s less about which technique you do and more about the attention that you’re paying.
— Gita Brown
Keep that in mind through what follows. The instructions below are guides, not specifications.
Technique 1: The Physiological Sigh — A Fast Reset
How it is taught. One full inhale, then a second smaller inhale on top of it — Brown calls that second one a sip of breath — then immediately a big, quick exhale. It goes out fast. No counts, no durations.
Route. She does it in through the nose and out through the nose, which she cheerfully flags as her yoga bias, and notes most people teach in through the nose and out through the mouth. Either is fine.
How many. One to three is enough — she says so twice.
What it does. Her explanation is that the body sighs spontaneously when carbon dioxide builds up in the brain — after a stretch of sustained concentration, after a tantrum, in freeze or panic states. Doing it deliberately restores the balance, which she associates with feeling steadier and more emotionally level.
The cockpit use case she gives is specific and realistic: a student pilot established on final, having just read back an instruction from ATC, feeling the pace pick up as the landing configuration comes next. Stable, in control, with a moment to spare — take one sigh and continue.
Technique 2: Coherent Breathing — Training Recovery
How it is taught. Equal inhale, equal exhale, with no pauses in between. The pace is roughly five or six breaths a minute — a figure Brown immediately softens by saying you do not need to be that granular. If it helps to have something for the mind to hold, count silently up to five or six on the way in and on the way out.
Route. Explicitly does not matter. Nose, mouth, any combination — breathe however your body will breathe on the day.
Setup. Before the practice she walks through posture: feet flat and evenly placed under the knees, weight even on the sit bones, awareness traced up the spine, shoulders released, jaw released, crown of the head lifting as though on a thread. You can also stand or lie down.
How long. The guided practice on the episode runs about two to three minutes. Describing her own routine, she suggests around three to five minutes — and pairing it with something you already do, such as immediately after lifting weights, which she rates highly.
What it does. This is the heart rate variability practice. HRV is the natural variation in time between heartbeats, and she describes it as a window into recovery and resilience — evidence that your system can move into a high-performance state and then come back down. Higher is better. Coherent breathing works the parasympathetic, rest-and-recover side of that balance.
Niehaus adds a practical corroboration: his wearable shows HRV and its stress metric moving in opposite directions, and he can watch HRV decline hour by hour across a demanding flying day, then recover afterward. Brown’s advice on wearables is to give one about six months of data before you trust what it tells you.
Technique 3: The Triangle Breath — Downshifting
This one is a visualization, not a count — which is the detail most often reported incorrectly.
Picture an equilateral triangle. The first line, going up, is the inhale. The line going down and then the line across back to the start are the exhale. So the exhale covers two of the three sides, making it naturally longer than the inhale. There are no seconds and no numbers attached to any of it.
Once you have settled into the rhythm, pauses get added — first a micro-moment at the top of the triangle, then another after the exhale. On the across portion, you can draw the abdomen in slightly to empty the last of the breath.
Brown offers variations for how people’s minds work: imagine the triangle being drawn, or an outline filling in; give it a color; or trace it with a finger if you are the kind of person who needs to move.
When to use it. Deep downshift — the end of a long duty day, or in bed when sleep will not come. To finish, release conscious control, sit quietly, then wiggle fingers and toes and take a few short, sharper breaths to bring your energy back up before returning to the day.
Safety Notes the Episode Is Careful About
Brown is more cautious than most breathing content, and these caveats belong with the techniques:
- If you feel light-headed or dizzy during coherent breathing, stop. Sigh it out, sit for a moment, and resume only when you are ready.
- If a given pace does not suit you, use your own — an easeful pace beats a prescribed one.
- If you practice while driving, keep your awareness on the road; she notes awareness can get a little fuzzy during the practice. The same caution applies to any phase of flight requiring your full attention.
- Slowing down is not right for everyone. She says she would not give this practice to someone who is already sluggish, low, or stuck — more downshifting is the wrong direction for them.
- She deliberately declines to teach the rapid, energizing, hyperventilation-style practices on a podcast, because they need in-person supervision and can cause someone to pass out.
That last point is worth repeating for anyone exploring breathwork independently. Brown notes that searching online turns up the good along with the bad, including advice from untrained people — and when that fails you, the wrong conclusion to draw is that breathing practices do not work for you.
Why Shallow Breathing Becomes the Default
Most people’s baseline pattern, Brown says, is shallow, quick, and high in the chest — up under the collarbones. She associates that pattern with a hyper-excited brain, difficulty focusing, and heightened anxiety, and offers a reframe worth sitting with: it may not be that you have anxiety, but that you have a breathing pattern that is not serving you.
A note on the physiology: she compresses this explanation and openly says she is skipping the science. The underlying mechanism is real but is not laid out in the episode, so treat this as a practitioner’s framing rather than an established chain of causation.
Posture is the constraint. Hunched shoulders and a rounded upper back limit how far the diaphragm can travel, so what feels like a deep breath is functionally much shallower. Her interventions include posture work and raising the arms overhead and lowering them — lifting the arms makes space so air comes in, lowering them reduces the space and pushes air out. She uses this with clients who have limited conscious breath control after a stroke or with cerebral palsy.
Breath as shape change. The diaphragm sits at the base of the ribs and pulls down and outward — she stresses it is three-dimensional, flaring the ribs outward. That creates a pressure difference, and the atmosphere equalizes it by pushing air in. Niehaus finds this counterintuitive in a useful way: you are not forcing air into your lungs so much as making room and letting it arrive.
The Aviation Version of the Same Idea
The best aviation-native moment in the episode comes from Niehaus. At high altitude, aircraft oxygen systems switch from passive delivery to pressure demand, because ambient pressure is too low for the diaphragm to draw air in on its own. The smallest inhalation cracks a valve and oxygen is pushed into your lungs — a strange sensation the first time. Brown uses it to reinforce the pressure-differential model of ordinary breathing.
She also reframes the pre-flight self-assessment: pilots study the aircraft’s operating handbook in detail, and there should be an equivalent ground session on how your own body works. Breathing is part of the system you are responsible for.
And there is a long-game argument. Poor posture combined with no exercise is what eventually stops people flying — her stated goal for listeners is that they still be flying in their eighties.
If Breathing Practice Has Never Worked for You
Two of the most useful ideas in the episode are aimed at people who have already tried and concluded it is not for them.
Reversed breathing. Some people draw the belly in on the inhale and push it out on the exhale — the opposite of the efficient pattern. Brown says this can follow a virus, long COVID, physical trauma, or surgery, and that she developed it herself after COVID. It creates anxiety mechanically, because you are shrinking the space at the moment you are trying to fill it. She points to a series of short breathing-retraining videos published by University College London Hospitals as a way to check yourself.
You may just not have found your entry point. Her illustration is a fifteen-year-old with asthma who was pulled out of a spin class and sent to yoga instead, and who came up afterward astonished at having taken a full, complete breath for the first time.
Resources the Hosts Recommend
- University College London Hospitals breathing-retraining video series — short videos aimed at breathlessness, asthma, and post-COVID recovery; useful for spotting a reversed breathing pattern.
- Insight Timer — largely free, with well-vetted teachers.
- Yoga with Adriene — a breathing playlist and a nighttime yoga session Brown rates highly.
- Calm — Niehaus’s pick; Brown likes their paced bedtime sessions.
- Wim Hof — mentioned with genuine caution. Brown has not done the method, considers it aggressive and closer to forced hyperventilation, and advises against going too far too fast, while noting others she trusts find it valuable.
One practical note the hosts raise: many employers offer a fitness or wellness allowance that will cover an app subscription, and some health insurers treat a gym membership as preventive care. Worth checking before you pay out of pocket.
The Bottom Line
Match the tool to the moment. The physiological sigh is for the seconds after a startle. Coherent breathing is conditioning — a few minutes regularly, ideally attached to something you already do. The triangle breath is for the end of the day, when the goal is genuinely to power down.
But the episode’s real argument is gentler than any of that. Five or ten minutes a day, done imperfectly, beats a precise technique you never practice. There is no gold standard to hit and no way to do it wrong.
Frequently Asked Questions
What is the physiological sigh and how do you do it? One full inhale, then a second smaller inhale on top of it, followed immediately by a big, quick exhale. Gita Brown teaches it without counts or durations, and says one to three repetitions is enough. Either nose-to-nose or nose-to-mouth is fine. It is intended as a fast reset after a startle response.
What is coherent breathing? Equal inhales and exhales with no pauses, at roughly five or six breaths per minute — though Brown stresses you do not need to be that precise. The guided practice in the episode runs about two to three minutes; she suggests roughly three to five minutes as a regular practice. It targets heart rate variability and the body’s rest-and-recovery response.
How does the triangle breath work? It is a visualization rather than a count. Picture an equilateral triangle: the line going up is the inhale, and the line going down plus the line across are the exhale — so the exhale is naturally longer. Pauses are added at the top and after the exhale once you settle in. There are no prescribed second counts. It is used for deep downshifting at the end of a day or for sleep.
Do pilots have to breathe through the nose? No. Brown notes nasal breathing filters, warms, and slows the incoming air — the slowing being what she values, since it gives you more control over pace. But she is explicit that there is no right or wrong way, and for coherent breathing she says the route does not matter at all.
Is breathing practice safe for everyone? The episode is careful here. If you feel light-headed or dizzy, stop and rest. Use your own comfortable pace rather than a prescribed one. Take care if practising while driving, as awareness can become fuzzy. Brown also notes that slowing practices are not appropriate for someone already feeling low or stuck, and she declines to teach rapid hyperventilation-style techniques without in-person supervision because they can cause fainting.
What if breathing exercises have never worked for me? Brown offers two explanations. You may have a reversed breathing pattern — drawing the belly in on the inhale — which can follow a virus, long COVID, trauma, or surgery, and which she suggests checking against breathing-retraining videos from University College London Hospitals. Or you simply may not have found the approach that suits you yet.
