“We underestimate how many people live in the gray zone of respiratory health — not sick enough for a diagnosis, but not operating at full capacity either. Small changes in lung function can meaningfully affect performance, recovery, and wellbeing. The beauty of what Climatic is doing is bringing those invisible shifts into view, giving people real feedback on their respiratory resilience outside of a clinic.”
