How to use it
- 1. Sit upright, feet flat, screen at arm's length.
- 2. Breathe through the nose, low into the belly, no strain.
- 3. Follow the ring: expanding means inhale, shrinking means exhale.
- 4. If holding feels uncomfortable, set both holds to zero and just pace the breath.
Two to five minutes is the useful dose before a decision. Longer sessions are fine but repeatability beats duration. The practice explained →

About this tool
How long should a session be?
Two to five minutes is enough to be useful as a state change. Longer is fine but the point is repeatability — a practice you actually do before decisions beats a perfect one you skip.
Is breathwork a treatment for anxiety?
No. Slow-paced breathing is studied as a self-regulation practice and many people find it calming, but this is not a medical intervention and nothing here replaces professional care.
