The best leaders keep a cool head under pressure. But even the masters can wobble. Learn how to stop stress reactivity in its tracks, & regulate your emotions under pressure.
This is a comprehensive programme to help you understand your physiology better. It takes the guesswork out of stress optimisation & emotional regulation working with science, technology and your own personal data to give you a window onto the inside.Other coaching modalities including NLP and hypnosis are available. The latest in VO2 max testing is also available on request,
Identify your breathing blue print. See your live respiratory chemistry and measure how efficently you deliver oxygen to your brain & vital organs.
Develop an awareness & understanding of your breathing habits & how they impact your oxygen delivery. Learn what it means to be in homeostasis and the connection between your emotional states, your breathing mechanics and your respiratory chemistry.
Identify unhelpful habitual behaviours & learn how to re-gain control & make your physioloy work for you before symptoms take hold.. Build stronger resilience to mitigate stress impacts.
Behaviour change requires practice! Train with simulated fear -inducing experiences to develop your ability to regulate your emotions, with better adapted breathing behaviours.
Package price: £899 (includes one week technology rental)
Technology rental: £199/week
Available in person (London UK only).

Step inside a first-of-its-kind pop-up lab designed to help you see — and feel — how your body responds to pressure.
This 20-minute experience measures your breathing baseline, places you in a short VR-based stress simulation, and guides you through a recovery reset — all while you watch your breathing waveform in real time.
For a limited time, experiences are FREE. Book your session below.
I’m Anna Stark, founder of Stark Naked and creator of the NKD Breathing Lab - a live testing ground for the next generation of breathing science and performance tech.
After two decades leading global teams in sport and sporting goods, I retrained in breathing behavioural science and modern psychology, and I’m now completing an MSc in Human Performance Optimisation.
My work bridges research and real life, helping people turn physiological insight into practical tools for calm & clarity.
Inside the Lab, you can expect:
Duration: 20 minutes
Location: Fitzrovia, Central London

Your breath is more than mechanical — it’s behavioural and biochemical.
Every pattern tells a story about how your nervous system handles stress.
The NKD Breathing Lab helps you see those patterns clearly, giving you practical tools to regulate and recover faster — in work, sport, and everyday life.
About the lab:
The NKD Breathing Lab is a temporary data-driven experience.. Using capnometers linked to our training app, we measure end-tidal CO₂ and breathing rhythm to show how physiology shifts under pressure — and how quickly it can be restored.
It’s the first step in our broader mission: helping people build calm, adaptable nervous systems through science-based breathing.

What happens to your breathing under pressure?
How much oxygen are you actually getting to your brain?
→Stressed-out professionals who feel wired, tense, or close to burnout — and want to understand what’s happening in their body.
→Students and high performers facing exams, deadlines, or big presentations who struggle to stay calm under pressure.
→Coaches, trainers, and wellness leaders who want to deepen their understanding of breathing science and self-regulation.
→Teams and organisations exploring innovative ways to manage stress, recover faster, and perform with composure.
→Anyone who’s curious about how their breath reveals what their nervous system is really doing — and how to change it.
