Find your resonance breathing rate

Slow-paced breathing is one of the few HRV levers that genuinely does something in the moment — but “breathe at five or six per minute” leaves out the part that matters: which rate is yours. This walks you through six slow rates and settles on the one that feels most calming, then hands you a pacer set to it.

A practical self-tuning aid — not a lab test

The clinical way to find your resonance rate measures your heart-rate swing live at each breathing speed. We can’t see your heart from a web page, so this does the honest next-best thing: you breathe along at six slow rates and tell us which felt most settling. That’s a good-enough personal starting rate to practice at — not a medical measurement.

You’ll step through six paced rates, from 7.0 down to 4.5 breaths per minute. Follow the circle: breathe in as it grows, out as it shrinks. After each one, tap how settling it felt. Sit upright, breathe through your nose if you can, and let the exhale be unhurried. Each rate runs about 45seconds — move on whenever you’re ready.

Be clear-eyed about what it’s for: the in-session calm is real, the durable resting-HRV gain mostly isn’t. For why slow breathing helps how you feel without reliably moving your overnight number — and what does and doesn’t shift HRV — see the HRV guide.
