Heart Coherence Breathing (5-5)
Heart coherence — also called coherent or resonance breathing — is a slow, even rhythm of five seconds in and five seconds out, about six breaths a minute. At that pace your heart rate, breath and blood pressure fall into sync, a state linked to calm, clear focus.
It's one of the most studied breathing practices, popular for building focus, steadying emotions and raising heart-rate variability (HRV), a key marker of resilience.
How to do heart coherence breathing
- 1Sit tall and relax
Settle into a comfortable upright posture and let your shoulders drop.
- 2Inhale for 5 seconds
Breathe in smoothly through your nose for a count of five.
- 3Exhale for 5 seconds
Breathe out just as smoothly for a count of five — no pause between phases.
- 4Keep the rhythm
Continue this even 5-5 wave for 5–10 minutes, letting the breath become effortless.

Why it works
About 0.1 Hz (six breaths per minute) is the baroreflex resonance frequency, where heart rate naturally syncs with the breathing cycle and HRV peaks. Alpha (≈10 Hz) rises clearly across the frontal-parietal region, and the prefrontal cortex regulates the amygdala more effectively — calm, focused control.
Benefits
- Sharp, sustained focus without tension
- Raises heart-rate variability (HRV)
- Smooths out emotional ups and downs
- A steady baseline practice for daily stress
When to use it
Use heart coherence for deep-work sessions or whenever you want to feel calm and clear at once. In Inhale it's tagged Focus and paired with a live brainwave visual.
Heart Coherence FAQ
What's the difference between coherent breathing and box breathing?+
Coherent breathing has no breath-holds — it's a continuous 5-5 wave aimed at HRV and focus. Box breathing adds equal holds and is more of a quick reset. Both target calm alpha activity.
How long until I feel the effect?+
Many people feel steadier within a few minutes. For HRV benefits, aim for 5–10 minutes; Inhale runs a guided 10-minute session.
Is six breaths per minute right for everyone?+
It's the average resonance rate. Some people feel best slightly faster or slower, but 5-5 is a reliable place to start.
