Why Paced Breathing Calms You
When you inhale, your heart rate naturally speeds up slightly. When you exhale slowly and smoothly, the vagus nerve releases acetylcholine, signaling your sinoatrial node to slow cardiac contractions. Paced breathing restores balanced heart rate variability (HRV) within just 2 minutes.
