The breathwork encyclopedia.

Breathwork for Beginners: A 4-Day Learning Path

A four-day reading and practice path for people new to breathwork. Read the map, take a CO₂ baseline, choose a first practice, then build rhythm and recovery tools.

Breathwork for Athletes: A 5-Day Learning Path

A five-day reading and practice path for athletes. Map the performance jobs, measure CO₂ and power, then start cadence and priming work.

Sleep Restoration Path: A 4-Day Learning Path

A four-day learning path for people rebuilding sleep — nasal breathing, evening wind-down, and pre-sleep breathwork.

Anxiety Recovery Path: A 4-Day Learning Path

A four-day learning path for people working through chronic or recurring anxiety. Match tools to states, drill resets, and add daily coherence.

Box Breathing: The 4-4-4-4 Structured Reset

A four-count inhale, hold, exhale, hold — the same technique used by Navy SEALs, ER physicians, and elite performers to bring composure under pressure without sedation.

Coherence Breathing (5.5-5.5): The HRV-Peak Rhythm

Coherence breathing sits near 5.5 breaths per minute — within the common adult cardiovascular resonance range. It can raise in-session heart rate variability, although each person's exact resonance pace differs.

The Physiological Sigh: A Brief Double-Inhale Technique

A double inhale through the nose followed by a long exhale through the mouth. Learn what research tested, where a few cycles fit, and how to try it safely.

Breathwork for Anxiety Relief

Not every anxious state responds to the same breath. Panic wants a fast reset. Chronic low-grade anxiety wants a coherence habit. Here is how to match the technique to the state.

Breathwork for Sleep Onset

You cannot force yourself asleep, but you can reliably reduce the arousal that keeps you awake. Long exhales, low pace, no counting acrobatics — that is the goal.

Breathwork for Focus and Concentration

For focus, you want composure without sedation. That points to box breathing or a light coherence practice — not the long exhales that make you sleepy.

What Is Breathwork? A Practical Beginner Guide

Breathwork uses the one automatic system you can consciously steer — breathing — to influence nervous-system state. Here is the plain-English map before your first test or technique.

CO₂ Capacity Builder: How the Program Works

A 10-session box-breathing program scaled to your latest CO₂ tolerance baseline, with progress driven by completed sessions.

Slow Breathing Mastery: How the Program Works

A 14-session progression from comfortable extended-exhale practice toward slow coherence breathing, without promising a specific resting rate.

Deep Focus Protocol: How the Program Works

A 10-session coherence-breathing program designed as a repeatable pre-focus onramp.

The Auralize CO₂ Tolerance Test

Auralize measures one slow, controlled exhale after a guided warm-up. It is a proprietary respiratory-control baseline—not a blood-gas test or a BOLT breath hold.

The BOLT Test: What It Measures and How to Interpret It

BOLT times a comfortable post-exhale pause to the first clear urge to breathe. It is a subjective training baseline—not a direct oxygen, CO₂, or lung-function measurement.

The Resting Breath Rate Test

A quiet breathing-frequency count that provides one useful respiratory vital sign. It must be interpreted with age, health, symptoms, medication, and measurement conditions.

Box Breathing vs 4-7-8: Which One Should You Use?

Box breathing gives you structure without sedation. 4-7-8 gives you deep downshift. They are not interchangeable — here is how to choose.

Coherence Breathing vs Generic Slow Breathing

Slow breathing is any pattern slower than resting. Coherence is a specific rate — 5.5 BPM — chosen to match the cardiovascular resonance frequency. The distinction matters.

Wim Hof vs Slow Breathing: Different Tools, Different Jobs

Wim Hof-style breathing lifts arousal and shifts blood chemistry. Slow breathing lowers arousal and raises HRV. They do opposite things and can both belong in a week.
