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.
