RFB is the clinical name for coherence breathing. Individual resonance frequency varies slightly with body size — larger frames often resonate slightly below 5.5 BPM.
Breathing at the individual's cardiovascular resonance frequency to maximise HRV. Typically 5–6.5 BPM.

Coherence Breathing (5.5-5.5): The HRV-Peak Rhythm
Coherence breathing sits at 5.5 breaths per minute — roughly the resonance frequency of the cardiovascular system. It is the single most reliable way to raise heart rate variability on demand.

HRV and Coherence Breathing: What the Research Shows
Heart rate variability rises when the breath is slow, steady, and near the cardiovascular resonance frequency. Here is the mechanism and the evidence.
