You don't find calm. You return to it.
This 90-second breath test shows you how fast you return right now. Not a verdict. A starting line.
What's your vagal tone?
It measures your CO₂ tolerance and breathing efficiency, a direct proxy for vagal health, nervous-system regulation, and stress resilience.
First, sit comfortably with a tall, straight back. Please don't take this while driving, standing, or in water.
How it works

2After the last breath, let it out naturally, don't force it, then pinch your nose and start the timer.
3Tap stop at your first urge to breathe.

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