Why this exists Resonance 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. This matters most for people with heart failure with reduced ejection fraction (HFrEF), where sympathetic overdrive is both a symptom and an accelerant of disease progression. Bernardi et al. (1998) demonstrated that slow breathing at 6 bpm improves oxygen saturation and exercise tolerance in CHF patients, with effects visible after a single session. A follow-up study (Bernardi et al. 2002) showed that slow breathing also increases arterial baroreflex sensitivity in CHF — a marker strongly associated with prognosis. This app is a habit tool that makes daily practice frictionless: open terminal, run breathe , follow the bar. It is not a medical device. The science in brief Why 6 breaths per minute? The cardiovascular system has a resonance frequency — typically between 4.5 and 6.5 bpm in adults — at which heart rate oscillations are maximally amplified (Vaschillo","default_branch":null,"files":null,"tree":[],"storefront":"/r/marekkowalczyk","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/marekkowalczyk/breathe-cli/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
