Coherent Breathing (5.5 Breaths Per Minute)

What is Coherent Breathing (5.5 Breaths Per Minute)?

Breathing at exactly 5.5 breaths per minute (5.5 seconds inhale, 5.5 seconds exhale) which research shows maximizes heart rate variability (HRV) for most adults. This rate aligns breathing with the baroreflex — the body's blood pressure regulation system — creating 'resonance' in the cardiovascular system. It is the simplest evidence-based breathing practice: just breathe at this rate, and your autonomic nervous system optimizes itself.

How do you do Coherent Breathing (5.5 Breaths Per Minute)?

1. 1.Sit comfortably with good posture or lie down. Use a pacing tool — a metronome app set to visual cues, or the Breathing App (by Eddie Stern, free) which provides a visual expanding/contracting circle at the correct 5.5 bpm rate
2. 2.Inhale slowly through your nose for 5.5 seconds, letting your belly expand first, then your lower ribs, breathing smoothly and continuously — no sudden gulps
3. 3.Without pausing at the top, transition smoothly into a 5.5-second exhale through your nose, letting the air flow out evenly and completely. The breath should feel like a gentle wave — no sharp edges between inhale and exhale
4. 4.Continue this smooth, even rhythm for 10-20 minutes. Your mind will wander — that is fine. When you notice you have drifted off the rhythm, gently return to the pacing cue. No force, no effort in the breathing itself
5. 5.Practice daily for maximum benefit. Research shows HRV improvements become more pronounced after 4-6 weeks of daily practice. This can also be used as a pre-sleep routine or during work breaks. Some people find 5 bpm or 6 bpm works better — test with an HRV monitor if available.

How long does it take?

10-20 minutes per session, daily.

Is it hard to start?

easy.
