Summary

This study aims to understand why breathlessness varies among people with different lung diseases like COPD, asthma, and ILD. Researchers will measure lung function, exercise ability, and breathing patterns in 75 participants (50 with lung disease and 25 healthy controls). The goal is to gather detailed information to help develop better treatments for breathlessness.
