🫁 BOLT Test — Do This Before Filling in the Form
1
Sit quietly for 2 minutes. Breathe normally through your nose.
2
Take a normal breath IN through your nose.
3
Take a normal breath OUT through your nose. Then pinch your nose closed.
4
Count seconds until you feel the FIRST definite urge to breathe. Release nose and breathe normally. Note that number.
This is not a maximum breath hold. Stop at the first urge — the moment you feel air hunger. If you gasped when you released, you held too long. Repeat after 2 minutes rest. Enter your score in Section 2 below.
