Summary
A terminal-based application for paced resonance breathing training (around 6 breaths per minute) designed to improve cardiac vagal tone. The tool is macOS-only, single-file, with no dependencies. It explains the physiological mechanism behind resonance breathing — how slow breathing amplifies respiratory sinus arrhythmia (RSA), strengthens vagal outflow, improves baroreceptor sensitivity, and shifts autonomic balance away from sympathetic dominance.
Key quotes
· 3 pulledResonance breathing — slow, paced breathing at around 6 breaths per minute — is one of the few non-pharmacological interventions shown to improve cardiac vagal tone.
The mechanism is straightforward: slow breathing amplifies respiratory sinus arrhythmia (RSA), the natural heart-rate variation linked to the breath cycle.
Stronger RSA means stronger vagal outflow, which in turn improves baroreceptor sensitivity and shifts autonomic balance away from sympathetic dominance.
