Module 2 · Breath as Medicine

Clinical breathwork protocols

Three evidence-based techniques — each produces measurable physiological effects in under 10 minutes.

Protocol 1

Coherent Breathing — 5.5 BPM

Breathing at exactly 5.5 breaths per minute synchronises the cardiovascular system’s resonance frequency with respiratory rhythm — producing maximum HRV. Inhale slowly through the nose for 5.5 seconds. Exhale slowly for 5.5 seconds. Continue for 7 minutes. +50% HRV (Bernardi, Circulation 2001).

Protocol 2

Physiological Sigh

The fastest known technique for reducing acute stress. Full inhale through the nose, then a short second sniff, then a long complete exhale through the mouth. Even one cycle produces measurable parasympathetic activation (Balban et al., Cell Reports 2023).

Protocol 3

Nadi Shodhana — Alternate Nostril Breathing

Right hand: thumb over right nostril, ring finger over left. Close right, inhale left for 4 counts. Close both. Release right, exhale for 4. Inhale right. Close. Exhale left. One cycle. 7 minutes daily — associated with hemispheric balance and cognitive improvement.

⚠️ Medical disclaimer: Consult a physician before practice if you have cardiovascular, respiratory, or psychiatric conditions. Stop immediately if you feel faint.

Breath as medicine

The Bioveda program trains providers to prescribe these protocols clinically. The first prescribable unit is a 5-minute Breath Awareness audio.
