Resonant Breathing
Breathing at your personal resonance frequency — usually 5.5–6 breaths per minute — to maximise heart rate variability and vagal tone.

Resonant breathing (sometimes used interchangeably with coherent breathing) means breathing at the cadence where your cardiovascular system resonates — the frequency at which heart rate variability peaks and the body's reflex loops align. For most adults that frequency is between 4.5 and 6.5 breaths per minute. A simple 5-second inhale, 5-second exhale puts you in the centre of that range.
Why it works
The work of Paul Lehrer and Richard Gevirtz established that breathing at resonance frequency drives the largest possible oscillations of heart rate, which trains baroreflex sensitivity. Higher baroreflex sensitivity correlates with reduced anxiety, lower blood pressure, and better emotional regulation — the same downstream benefits seen across biofeedback clinical trials.
How to do resonant breathing
- Sit upright with a tall, easy spine. Soften the belly.
- Inhale through the nose for 5 seconds. Let the breath be quiet and low.
- Exhale through the nose for 5 seconds with the same smoothness.
- Continue without holds. Aim for 10 minutes at first, building to 20.
- Optional: fine-tune to your personal resonance (4.5–6.5 BPM) with a HRV biofeedback device.
When to use it
- Daily — once or twice — as your foundational practice.
- Before sleep, paired with a body scan.
- Anytime stress is chronic rather than acute.
Frequently asked questions
How is resonant breathing different from coherent breathing?
They overlap heavily. 'Coherent' refers to a standardised 5-5 cadence; 'resonant' refers to whichever cadence is your personal cardiovascular sweet spot. For most people, 5-5 is close enough.
Do I need a HRV device?
No. The benefit of paced breathing at ~5.5 BPM is well-documented even without biofeedback. A device just helps you find your exact personal frequency.
