Myths
I smoke — what does my result mean?
By BreathTestOnline Editorial Team· Updated September 26, 2026 · Wellness guide, not medical advice
Short answer
Smokers often score under 25s. Treat a low score as motivation, not a diagnosis.
Smoking irritates airways and reduces efficiency, so lower holds are common. The good news: quitting improves breathing measures within weeks.
This test can't detect COPD or any disease. Only spirometry with a clinician can.
If you smoke and want to quit, consider a quitline or clinician — and retest monthly to watch your trend improve.

Myths
Is a 30-second breath hold bad?
No — 30 seconds is perfectly average and fine for most adults.
Myths
Should I hyperventilate before the test to score higher?
No — never. It masks your urge to breathe and can cause blackout.
