Buteyko Control Pause

Measures how long you can comfortably hold your breath after a normal exhale - your Control Pause.

1. Settle - sit still and breathe quietly through your nose.
2. Bell 1 - breathe in, then out. At the end of your exhale, hold your nostrils closed with your fingers, then tap 'Start hold'.
3. Bell 2 - timer starts. Tap again at the first urge to breathe - not when desperate.
4. Release - breathing should return to normal quietly. If you gasped, you held too long.
