What Functional Breathing Really Means
Discover how functional breathing and breathing mechanics shape your stress response, physiology, and overall performance.
In today’s video, Martin McPhilimey — respiratory & sleep scientist and founder of the School of Breath Science — breaks down the real physical mechanics of breathing and shares a powerful story from Brazilian Jiu-Jitsu that reveals how unconscious breathing patterns can trigger panic, overwhelm, or shutdown.
What You’ll Learn
You’ll learn:
• Why breathing mechanics are more than “just diaphragm breathing”
• How posture, rib-cage mobility, and pressure–volume changes influence your breath
• How stress, past experiences and conditioning can influence breathing behaviour
• The Stress Breathing Paradox and how stress can influence breathing patterns
• What functional vs. dysfunctional breathing looks like in real time
• How conscious awareness and respiratory motor control can influence breathing behaviour
Whether you’re a breathwork facilitator, health coach, therapist, or someone wanting to understand your body better, this video gives you a clear, evidence-informed explanation of how breathing truly works — far beyond what most breathwork trainings teach.
