Diaphragmatic (belly) breathing engages the primary breathing muscle (diaphragm) for a fuller breath, compared to shallow chest breathing that primarily uses secondary respiratory muscles. Benefits: greater tidal volume, better gas exchange, lower respiratory rate, reduced anxiety through vagal nerve stimulation. Most adults breathe primarily from the chest — poor posture, stress and sedentary lifestyles reduce diaphragmatic engagement. Consistent diaphragmatic breathing practice improves exercise performance, recovery and stress resilience. Nasal breathing during low-intensity exercise also enhances nitric oxide production and oxygen delivery.
Key points
- Uses diaphragm for deeper, more efficient breath
- Activates parasympathetic nervous system
- Reduces respiratory rate and anxiety
- Nasal breathing enhances nitric oxide production
