Nervous System Regulation Through Breath
Your Nervous System
Score Check
4 simple checks. No wearable. No lab. Just a few honest minutes.
This is a check-in, not a competition.
Check-in 1 / 4
CO2 Tolerance (BOLT)
Sit quietly for a minute. Take a normal breath in and out, then pinch your nose and time how many seconds pass until the first real urge to breathe.
Most people land somewhere between 5 and 30 seconds.
Check-in 2 / 4
Exhale Length
Take a full, deep breath in. Exhale as slowly and steadily as you can, timing it from start to finish.
A healthy benchmark is 11+ seconds.
Check-in 3 / 4
Maximum Breathlessness Test
Exhale normally, pinch your nose, and walk at a normal pace. Count how many steps you can take before you need to breathe.
Use this as information, not a competition.
Check-in 4 / 4
