Pattern
Coherent breathing
Coherent breathing: five seconds in, five seconds out, no holds. Six breaths a minute, the resonance frequency for most adults.
The pattern
5-5
When to use it
- When you want the most evidence-backed return per minute.
- Mid-morning, mid-afternoon, between tasks.
- As a daily anchor. Pick a time and stick with it.
- Five minutes is fair; ten is better if you have it.
How to do it
- 01Sit upright. Let the shoulders soften.
- 02Breathe in gently through the nose for five seconds.
- 03Breathe out through the nose or mouth for five seconds.
- 04Do not pause at the top or bottom. Keep the wave continuous.
- 05Aim for ease, not depth. Small, even breaths are the point.
- 06Continue for five to ten minutes.
What it does
Six breaths per minute sits inside the resonance frequency band, where heart rate, breath, and blood-pressure waves synchronise into a single oscillation. Heart-rate variability rises sharply at this rate, and most positive trials in the HRV biofeedback literature use sessions in this neighbourhood.
Research by Paul Lehrer, Evgeny Vaschillo, and others has shown that resonance-frequency breathing can produce measurable improvements in HRV, blood pressure, and various stress-linked outcomes when practised daily for ten to twenty minutes. The protocol works regardless of whether the user can perceive the heart-rate signal directly.
The point is the rhythm, not the depth. A big inhale defeats the purpose. A gentle, regular wave is the whole exercise.
