Practice gently. Stop if you experience dizziness, discomfort, anxiety, or strain. Avoid breath retention if you are pregnant or have cardiovascular, respiratory, or other medical conditions where breath holding may be inappropriate. Breath Lab is educational and practice-based. It does not diagnose, treat, cure, or replace medical care.

Choose a ratio

Start with a preset or set your own inhale, hold, exhale, and hold counts.

Follow the orb

The visual expands on inhale, holds steady during retention, and contracts on exhale.

Complete the rounds

One round is inhale, hold, exhale, hold. Skip holds by setting them to off.
