Breathing Tools
Stop counting manually. Use our precise visual timers to ensure accurate protocol execution for HRV biofeedback, sleep induction, and athletic performance.
Box Breathing
4-4-4-4 protocol for rapid autonomic regulation and stress management.
Open Timer →4-7-8 Sleep Protocol
Dr. Andrew Weil's method for combatting insomnia and reducing anxiety.
Open Timer →Resonance Frequency
Find your optimal breathing rate (usually 5.5 breaths/min) to maximize HRV.
Open Pacer →CO2 Tolerance Test
Assess your baseline stress levels by measuring your sensitivity to carbon dioxide.
Start Test →Apnea Tables
Generate custom O2 and CO2 training tables for freediving and breath-hold practice.
Open Generator →Physiological Sigh
Double inhale followed by an extended exhale. The fastest way to offload CO2.
View Guide →Alternate Nostril (Nadi Shodhana)
Balance the nervous system and improve hemispheric communication in the brain.
Open Timer →Buteyko Control Pause
Measure your breathing volume and track improvements in oxygenation.
Start Test →Wim Hof Protocol
Guided timer for hyperventilation cycles followed by retention times.
Open Timer →Running Cadence Metronome
Sync your breath to your footfalls (e.g., 3:3, 2:2) to improve endurance.
Open Tool →Tummo Breathing
Inner fire meditation technique for cold resistance and deep visualization.
View Guide →Holotropic Breathwork
Information on safely approaching altered states of consciousness via breath.

Which tool should I start with?
If you are new to breathwork, start with the CO2 Tolerance Test to establish your baseline. From there, Box Breathing is the safest and most universally applicable tool for daily stress management.
Are there contraindications for these tools?
Yes. Techniques involving hyperventilation (like Wim Hof or Holotropic) or intense breath holds (Apnea Tables) are contraindicated for pregnancy, epilepsy, severe cardiovascular disease, and history of aneurysms. Always consult a physician first.
Common Mistakes Across Modalities
- Mouth Breathing: Unless specifically instructed (e.g., the exhale of the Physiological Sigh), you should default to nasal breathing. The nose filters, warms, and humidifies air while releasing nitric oxide.
- Chest Breathing: Most beginners shrug their shoulders and inflate their upper chest. Proper breathing is diaphragmatic—the belly should expand outward on the inhale, while the chest remains relatively still.
Clinical Application Summary
| Physiological Goal | Recommended Tool | Mechanism of Action |
|---|---|---|
| Immediate Anxiety Reduction | Physiological Sigh | Alveoli reinflation & rapid CO2 offload |
| Sleep Architecture Improvement | 4-7-8 Breathing | Parasympathetic shift via prolonged exhale |
| Endurance / EPO Release | Apnea Tables | Simulated altitude / intermittent hypoxia |
| Pre-Workout Alertness | Wim Hof / Tummo | Sympathetic activation (Adrenaline release) |
