Breathwork Modalities Index

Hypoxic / Hypercapnic Training

Focuses on increasing carbon dioxide tolerance (lowering the central nervous system's sensitivity to CO2). Goal: Reduce minute volume, cure asthma, lower baseline anxiety.

• Buteyko Clinic Method - Dr. Konstantin Buteyko's foundational work.
• BOLT Scoring - The primary metric for this modality.

Common Mistakes

Pushing breath holds into the "hypoxic stress" zone too early, triggering cortisol release rather than vagal tone adaptation.

Sympathetic / Hyperventilation

Focuses on offloading massive amounts of CO2 to induce temporary alkalosis and trigger epinephrine. Goal: Acute immune response, athletic priming.

• Tummo / Wim Hof Method
• The Bohr Effect (Why you feel tingling)

Autonomic Synchronization

Focuses on precise respiratory rates to match the baroreflex. Goal: Maximize Heart Rate Variability (HRV).

• Resonance Frequency (5.5 BPM)
