Functional BreathingOxygen Advantage
Rewire how you breathe every day
Functional breathing is science-based and works at the physiological level. It improves sleep, reduces anxiety, boosts focus and athletic performance by retraining your breathing mechanics. You do not need to set aside 40 minutes in a dark room. You do it while you walk, while you work, while you lie in bed. It is the foundation of everything.
Three Dimensions of Functional Breathing
Biochemistry · CO2 tolerance
Carbon dioxide helps regulate breathing and the release of oxygen to tissues. BOLT gives a practical starting point for exploring your response to rising CO2, not a direct measurement of blood gases.
Biomechanics · 3D diaphragm expansion
The diaphragm works with your rib cage and abdominal wall. Comfortable breathing allows the lower ribs to expand forwards, sideways and backwards, without forcing a big breath or lifting the shoulders.
Cadence · Nervous system & HRV
Breathing rhythm interacts with heart-rate variability and the nervous system. A comfortable, slower rhythm can support settling and recovery. Your resting rate is a starting point, not an HRV measurement.
