The Vagal MethodVagal Tone Breath Test

What's your vagal tone?

This 60-second test measures your CO₂ tolerance and breathing efficiency — a direct proxy for vagal health, nervous-system regulation, and stress resilience.

How it works

1Follow 5 guided, relaxed breaths.
2After the last exhale, pinch your nose and start the timer.
3Tap stop at the first urge to breathe.
4Get your Vagal Tone Score + what to do next.

⚠️ This is not a breath-holding competition. Stop at the first sign of air hunger — not when you can no longer breathe.
