Technique

Resonance Breathing.

Resonance (or coherent) breathing means slowing to about six breaths a minute, roughly a five-to-six-second inhale and exhale. At that pace, heart rate and breath sync up, which is why it's the go-to for building a steadier baseline and training heart rate variability over time.

What It Is

Six Breaths a Minute.

Resonance breathing finds the pace where your cardiovascular system 'rings' most efficiently: for most people, around six breaths per minute.

Slowing to an even, smooth rhythm of roughly equal inhales and exhales puts breath and heart rhythm into step. Research on resonance breathing has looked at its effects on heart rate variability and cognition (Chaitanya et al., 2022, Cureus).

Unlike fast-acting resets, this one rewards practice. A few minutes a day, most days, is how you raise the calm, resilient baseline you carry into everything else.

The Pattern

How to Practice Resonance Breathing.

Aim for a smooth, even breath of about 5.5 seconds in and 5.5 seconds out, with no holds. Adjust until it feels effortless.

Inhale

Best for

Building a steadier daily baseline
Training heart rate variability over time
A calm, sustainable everyday practice

Go gentle if

The pace feels like effort: let the count come down until it's smooth
You need a fast reset: use the physiological sigh instead

Why Breethly

Find and Hold Your Pace.

Holding a precise, even six-breaths-a-minute rhythm by feel is surprisingly hard; most people speed up without noticing. Breethly's real-time feedback keeps you exactly on pace, and your Nervous System Score turns 'I did some slow breathing' into progress you can actually see.

Questions, answered.

Most people resonate at about six breaths per minute (roughly 5.5 seconds in and 5.5 seconds out), but the ideal can range from about 4.5 to 7 breaths per minute. The right pace is the one that feels smooth and effortless.

They're effectively the same idea: slow, even breathing at around six breaths per minute with no holds. 'Coherent breathing' usually refers to a fixed five-in, five-out pace; 'resonance' means tuning to your own most efficient rate.

You'll likely feel calmer within a single session. The baseline benefits, like a steadier, more resilient nervous system, come from regular practice over weeks, which is exactly what Breethly is built to help you sustain.
