World Lung Day

World Lung Day is observed annually on 25 September and coordinated by the Forum of International Respiratory Societies (FIRS).

The 2026 theme, **“A Lifetime of Lung Health,”** highlights the importance of protecting respiratory health at every stage of life — from childhood through older age.

Chronic respiratory diseases, including chronic obstructive pulmonary disease and asthma, are major noncommunicable diseases and share many preventable risk factors with other NCDs, including tobacco use, air pollution and unhealthy environments.

World Lung Day is an opportunity to call for stronger prevention, earlier diagnosis, equitable access to treatment and care, and policies that create healthier environments so that everyone can breathe cleaner air and enjoy better lung health throughout their lives.
