Your heartbeat speeds up a little as you inhale and slows as you exhale. This rhythm is called respiratory sinus arrhythmia. When you breathe slowly and evenly at about six breaths per minute, the heart and breath fall into a strong, smooth wave. Scientists call this resonance at about 0.1 hertz. It strengthens vagal tone, improves baroreflex function, and creates a coherent heart rhythm that supports calm attention.

The heart sends a steady stream of nerve signals upward through the vagus into brain centers that govern emotion, focus, and self-regulation. When the heart rhythm is coherent, those signals become ordered, which supports executive function and emotional stability. Studies suggest that cultivating sincere positive feelings while breathing smoothly increases this coherence and improves self-regulation.

Why this matters for spiritual practice:
Coherence widens access to the Net. Calm, ordered physiology lowers internal noise so subtle impressions can register. Slow, deep breath steadies attention, quiets reactivity, and helps you hold a clear target for recall work.

How to achieve it:
Sit upright with relaxed shoulders. Place one hand on your sternum to help focus on the heart area. Close your lips and breathe through your nose if you can. Inhale for about five seconds. Exhale for about five seconds. Continue for five minutes. Keep your breath gentle and quiet. While you breathe, bring up a simple heartfelt feeling such as gratitude or compassion. Let that feeling fill the chest as if the heart were breathing it. This pairing of slow rhythm and sincere emotion is what lifts coherence. If you like timing, aim for about six cycles each minute.

Before recall, do three to five minutes of coherent breathing and heart focus. State a clear intention for the recall target. Relax your attention. When impressions arise, jot short sensory notes before interpreting them. If the signal blurs, return to breath and feeling, then reopen to the target.

This is most effective when practiced regularly. Our nervous system functions just like a muscle. Short daily practice outperforms a single long session. Additionally, we can practice breathing anywhere, even if we don’t plan on meditating at that moment. The more often we practice syncing our hearts to our breath, the stronger our connection becomes in daily life.

Have you heard of heart-breath coherence? How do you relax into a meditative state?
