CONTROL UNDER PRESSURE CHALLENGE: INCLUDES A FREE 1:1 SESSION
Your breathing blueprint.
Your body is doing exactly what it has learned to do.
The question is whether it is working for you?
Under pressure, most people’s breathing works against them.
It’s not a character flaw. It’s a pattern…. and patterns can be retrained.
from our founder
A few years ago I followed a breathing practice that pushed big, fast breaths.
Within days, I was in hospital.
What I didn’t understand at the time was this:
“Overbreathing (taking in more air than your body needs) can lower CO₂ – disrupting blood flow and making symptoms worse, not better”
In my case, trying to “breathe deeper” was doing exactly that. No one had ever told me my breathing might be part of the problem. That’s why Stark NKD exists.

Science-led
Why "taking a deep breath"
isn't fixing this
Often advice skips the science of how your body actually works.
You’re not short on air.
Most people assume they need more oxygen. But big inhales can lower CO₂ too much –
which can worsen light-headedness, chest tightness, and that “air hunger” feeling.
CO₂ drives the system more than you think
When CO₂ is more stable, oxygen is delivered more effectively to tissues.
That’s when your system starts to come out of high gear.
“Breathe deeper” can keep the loop going
Pushing bigger breaths doesn’t fix the pattern. It can reinforce it – especially under pressure.
This has to work when it matters.
Not lying down. Not in perfect conditions.
In meetings, under pressure, mid-conversation – where your system actually shifts.
This approach is grounded in breathing physiology and human performance training in high-pressure environments.

Client stories
Deep breathing made me worse – now I know why.
I always thought deep breathing was the right thing to do when stressed. I recently lost my job and started to experience intense anxiety. The deeper I breathed the less air I was getting in. It was terrifying. My housemate stayed with me and called emergency services. He had his own story of burnout and difficulty breathing. It is such a relief to know what caused this and how to avoid this happening again.

More focus at work → less anxiety at home.
I’d been on mat leave for a year and felt really intimidated going back to work. So much had changed and I often felt foggy and anxious, struggling to focus. This made me feel like I didn’t belong and was failing at my job. I discovered I was mouthbreathing and chest breathing constantly. Once I could see these breathing habits I could undo them. This has really helped me focus better and improve my self-esteem.

FAQ’s
Breathe easy — Your questions answered
How much time each day?
15 minutes. You’ll also learn quick 60-second resets you can use anytime.
What if I miss a day?
No problem. You’ll get catch-up prompts and we’ll help you keep moving.
Is this safe during panic?
We teach gentle, CO₂-friendly resets you can use during spikes. If you have medical concerns, speak with your clinician.
I hate “deep breathing.” Will this help?
Yes. We don’t prescribe big inhales. We help you steady CO₂ and choose patterns that feel helpful in your body.
Do I need an app or equipment?
No. Audio lessons + simple prompts. Phone and headphones are plenty. London based participants can visit the lab to use the tech.
Is the quiz a diagnosis?
No. It’s an education tool that spots patterns linked to your symptoms and suggests next steps.
How fast will I notice a change?
Many people feel a shift within days. For others gradual changes occur over time. For many,finally understanding their symptoms is a gamechanger. If you don’t receive any benefit, our 14-day money-back guarantee has you covered.
Can I do this alongside therapy, medication, or training?
Most apps give you techniques to follow. We start by showing you how your breathing actually behaves, then personalise from there. No one-size-fits-all protocols.
How is this different from other breathing apps?
“I’m not a meditator - I’m not into spiritual stuff.”
Perfect. This isn’t meditation or mysticism. It’s practical, science-led breathing education you can do at your desk, eyes open, during a coffee break.
“I know nothing about breathing - will I get lost?”
We assume zero prior knowledge. Plain English, no jargon, no “breath rules.” We show you exactly what to try and what to notice.
"Is my coaching session confidential?"
Yes. All information shared with Anna is strictly confidential. Only share what you are comfortable sharing.
What if big breaths make me feel worse or dizzy?
We avoid over-breathing. If you feel off at any point, stop, use a gentle reset (we show you how), and return when ready. Persistent symptoms? Talk to your clinician.
What if nose breathing is hard?
That’s fine. Nose is often helpful, but mouth breathing is very common if the nose feels too “tight.” No right/wrong – we’ll find what’s helpful for your body.
Do you use long breath-holds or forceful techniques?
No. We don’t use long holds or forceful exhale drills in this challenge. Everything is gentle and exploratory.
Is this therapy or medical treatment?
No. It’s education and training. If you have diagnosed conditions or concerns, check with your clinician.
What happens when the 1:1 coaching special ends??
This is a special offer for the founding-cohort on a first-come-first-serve basis. This is available for a limited time only.
What comes after the 7 days?
An optional follow-on week to keep building your knowledge and skills, plus a live Founder Q&A to answer questions and help you plan your next steps.
Your breathing is either working for you or against you.
