What it is
Diaphragmatic Breathing (deep belly breathing with extended exhales) is a physiological regulation technique that engages the diaphragm to slow respiratory rate and reduce autonomic fight-or-flight arousal.
Why it works
Shallow chest breathing signals the brain that an emergency is occurring. Extending your exhale longer than your inhale stimulates vagal nerve activity, signaling physical safety to the nervous system:
Physiological Shift
Techniques like paced breathing and sensory grounding directly activate the vagus nerve, sending safety signals to the brain stem to turn down autonomic fight-or-flight arousal.
Interactive Pace Trainer
Use the pacer below to guide your breathing rhythm: inhale for 4 seconds, hold for 4, and exhale slowly for 6 seconds.
Paced Breathing Practice
Practicing with Camic
Camic walks you through breathing pace sessions as a real-time conversation, maintaining a steady cadence, monitoring your distress level, and helping your body settle.
Applied in real situations
