What is Atemstark?
Better breathing.
Better breathing.
Better health

Breathing is the one thing you do 20,000 times a day – yet almost nobody does it optimally.
Atemstark combines science, body awareness, and targeted breathing techniques to create measurable change in how you feel, focus, and perform. Whether the goal is stress resilience, athletic endurance, or deeper sleep – the method is practical, evidence-based, and accessible to everyone.

What breathing training does
Six ways breathing
Six ways breathing
changes everything
Each benefit is grounded in respiratory physiology – not wellness trends. These are measurable, reproducible outcomes of functional breathing practice.
Focus & Calm
Activating the parasympathetic nervous system lowers heart rate and blood pressure. Conscious, nasal breathing reduces mental noise and sharpens attention.
Sports & Endurance
Greater stamina and faster recovery through improved CO₂ tolerance and oxygen delivery to muscles. Energy-efficient breathing means more output with less effort.
Improved Metabolism
Enhanced circulation and O₂ delivery to vital organs and muscles. Proper breathing supports cellular energy production and waste removal.
Diaphragm & Posture
Correct breathing strengthens the diaphragm, core, and spine – improving posture and reducing the physical tension that builds with chronic shallow breathing.
Protected Airways
Nasal breathing warms, filters, and humidifies incoming air. Nitric oxide (NO) produced in the nasal sinuses opens airways and improves oxygen uptake.
Immune & Inflammation
Improved oxygenation and CO₂ tolerance support cell regeneration and help regulate inflammation – foundational to long-term health and resilience.

About Atemstark
Science-based.
Full Story →
Science-based.
Human-centred.
Built from experience.
I spent years in high-performance corporate environments – fast-paced, demanding, driven by constant output. I believed success meant pushing harder and resting less. Over time I realised: health and performance aren’t opposites. They depend on each other.
That insight led me to the Oxygen Advantage® method, functional breathing, and founding Atemstark – to share what I found with individuals, teams, and athletes who want the same.
Science-based, but simple
Every technique is grounded in physiology, supported by research, and easy to integrate into daily life.
Awareness & Balance
Breath is the bridge between body and mind – it regulates stress, sharpens focus, and restores calm.
Sustainability & Purpose
We create habits that last – improving wellbeing, resilience, and presence far beyond the training itself.
Questions
Frequently asked
Frequently asked
about breathwork
Everything you need to know before getting started with Atemstark. Breathing training in Zurich and online.
What is functional breathing?
Functional breathing supports optimal oxygen delivery, calmness, focus, and performance. It emphasises nasal breathing, diaphragmatic efficiency, and a healthy breathing rate. With simple daily techniques, most people improve energy, sleep, focus, and stress resilience.
How does the Oxygen Advantage® method work?
Oxygen Advantage® combines scientifically proven breathing exercises with practical techniques to improve CO₂ tolerance, oxygen uptake, focus, and respiratory efficiency. It includes light breathing, breath holds, and functional movement drills – tailored to your personal goals.
What results can I expect?
Clients typically experience improved sleep, better stress management, more energy, reduced breathlessness during exercise, fewer nasal obstructions, and increased mental clarity. Results often begin within the first 1-2 weeks of practice.
Who is functional breathing suitable for?
Busy professionals, parents, athletes, people recovering from burnout, or anyone dealing with stress or low energy. Those with dysfunctional patterns – nasal congestion, mouth breathing, chronic shallow breathing – benefit considerably.
Can breathing exercises reduce stress or anxiety?
Yes. Breathing directly influences the autonomic nervous system. Nasal, low, and slow breathing activates the parasympathetic system, reduces adrenaline, and improves emotional regulation. Many clients feel calmer within minutes during sessions.
How do I get started?
For companies and teams, we begin with an exploratory conversation to understand your needs and define a suitable format. Individuals and athletes can explore coaching options after an initial discussion. Just get in touch – no commitment needed.
