What is Oxygen Advantage Breathwork? A Functional Approach to Calm
The Oxygen Advantage method of functional breath training helps you breathe more efficiently, calm your body and build resilience to stress. Unlike simple deep breathing, Oxygen Advantage techniques train your body to tolerate carbon dioxide better, activate the parasympathetic (rest and digest) system and stabilise your breathing patterns — essential for anyone struggling with anxiety. It's a structured, science-backed approach that goes beyond basic relaxation techniques, providing practical tools for managing your nervous system. “The OA™ offers the potential to transform everything you thought you knew about your body, your performance and your health.” Patrick McKeown, Founder of OA
Understanding Anxiety and the Overloaded Nervous System
Many people today are living in a constant state of "fight or flight," with anxiety, tension and restlessness as daily companions. When the nervous system is stuck in overdrive, it becomes difficult to relax, focus or sleep. This state of chronic activation can leave the body and mind exhausted. You might find yourself constantly on edge, struggling to switch off and feeling overwhelmed by the demands of modern life. This isn't just a mental state; it has tangible physical effects, impacting your sleep, digestion and overall well-being. Breathwork and especially the Oxygen Advantage Training, offers scientific breathwork to optimise health, mental clarity and performance through tools to create calm from within.
How Breathwork Regulates the Nervous System and Reduces Anxiety
The way we breathe directly impacts our nervous system. Fast, shallow mouth breathing tells the body to stay in fight-or-flight mode, increasing anxiety and tension. Slow, nasal, diaphragmatic breathing tells the brain it’s safe to relax. The utilisation of breathing exercises by Oxygen Advantage® is underpinned by robust theoretical frameworks and scientific evidence teaching you how to breathe less and better. Specific techniques teach you how to calm the mind, slow the heart rate and regulate the nervous system. Over time, this reduces baseline anxiety and builds long-term resilience. By consciously altering your breathing patterns, you can directly work with breathwork for stress.

The Science of Breath and Calm: Why How You Breathe Affects How You Feel
Our breath is the remote control for our nervous system. Every inhale and exhale sends signals to the brain, telling it whether to relax or prepare for danger. Oxygen Advantage training focuses on carbon dioxide tolerance, teaching the body to become less sensitive to CO2 - a trigger for panic in anxious people. By practising breath-holding and slow nasal breathing, we train the body to feel calm even under stress. This helps prevent panic attacks, reduce daily anxiety and improve overall emotional balance. Essentially, you're retraining your body to respond differently to stress triggers.
