Your Breath Is a Nervous System Diagnostic.
Find Out What Yours Is Telling You.
In less than 3 minutes, this science-backed test reveals how your body handles stress — and gives you a custom breathing protocol to drive your nervous system.
Your Breath Is a Window Into Your Performance
Most high performers train their body and mind.
Almost none train the bridge between them.
Your breath is that bridge — a direct signal from your autonomic nervous system revealing how well you recover, regulate, and respond under pressure.
🫁 Short exhale? Your system’s stuck in “fight or flight.”
🌬️ Long, controlled breath? You’re wired for calm focus and deeper flow.
🔁 Somewhere in between? Your biology’s sending mixed signals.
This test measures your CO₂ tolerance — the single most overlooked metric behind focus, stress resilience, and sustained energy.

CO₂ Tolerance Exhale Test
Do this seated, nasal-only, and quietly.
Settle (30 sec): Sit tall. Breathe lightly through your nose. Relax your jaw, shoulders, and belly.
Prepare: Have a timer ready. Keep your lips sealed.
Normal inhale: Take a gentle, comfortable nasal inhale — not a max breath.
Start + Exhale: Start the timer and exhale slowly through your nose. Keep it smooth and steady. No forcing, no pauses.
Stop: Stop the timer at the first strong urge to inhale or when the exhale becomes choppy. Do not squeeze out the last air.
Record: Rest for 60 seconds and repeat once.
Submit: Enter the best of your two times below.
Quick tips (small): Nose only. No lip-pursing. Keep conditions consistent.
Safety note (small): Stop if you feel lightheaded. If you have respiratory or heart conditions, consult a clinician first.
Input field label: Exhale time (in seconds)
Helper text: Use your best of two attempts.
