BioResonance guide
How the BioResonance resonance breathing test finds your optimal breathing rate
BioResonance tests 6.5, 6.0, 5.5, 5.0, and 4.5 breaths per minute while measuring HRV response, RSA amplitude, phase synchrony, and coherence.
The test steps through slow breathing rates: 6.5, 6.0, 5.5, 5.0, and 4.5 breaths per minute. Each pace gives your body time to reveal how strongly heart rhythm follows breathing.
The protocol
The test steps through slow breathing rates: 6.5, 6.0, 5.5, 5.0, and 4.5 breaths per minute. Each pace gives your body time to reveal how strongly heart rhythm follows breathing.
What the app watches
BioResonance continuously estimates RMSSD, SD1, RSA amplitude, heart-rate oscillation amplitude, phase synchrony, coherence, and respiratory sinus arrhythmia gain.
What optimal today means
Your optimal resonance today might be 5.4 breaths/min. Tomorrow it could shift because posture, fatigue, hydration, illness risk, stress, and sleep all affect physiology.
Why this stands out
Instead of giving everyone the same breathing pattern, BioResonance treats resonance breathing like a personal lab test: measure the response, explain the mechanism, then train at the pace your body actually shows.
How to prepare
Use a compatible RR interval sensor, sit comfortably, avoid forcing deep breaths, and keep the test calm. Consistent posture and timing make results easier to compare.
