coherent breathing
A smooth five-count rhythm for calm, steady breathing.
traditional name: coherent or resonance-style breathing
A slow five-count inhale and five-count exhale.
The even rhythm is simple, repeatable, and useful when you want a calm baseline without breath holds.
Coherent breathing grew from heart-rate-variability and biofeedback research around slow, steady breathing rates.
Stay comfortable. Use a shorter count if five seconds feels too long.
these notes summarize research related to controlled breathing. individual results vary, so keep the practice comfortable and stop if you feel unwell.
Breathing at a rate of 5.5 breaths per minute with equal inhalation-to-exhalation ratio increases heart rate variability
5.5 breaths per minute with 5:5 ratio achieved greatest HRV increase
Significantly increased feelings of relaxation
Higher low frequency power indicating improved autonomic balance
Optimal pattern for HRV biofeedback training
The Impact of Resonance Frequency Breathing on Measures of Heart Rate Variability, Blood Pressure, and Mood
Breathing at resonance frequency was associated with HRV changes
Measured changes in cardiovascular markers and mood
Enhanced cardiovascular health markers
Effective for stress management and emotional regulation
