World Lung Day 2026 Theme

The theme of World Lung Day 2026 is “A Lifetime of Lung Health.”

The theme highlights the importance of protecting lung health from childhood through adulthood and old age, rather than focusing only on respiratory diseases after they develop.

The campaign emphasises four key areas:

• Lung development
• Lung growth
• Maintaining healthy lungs
• Healthy lungs throughout life

Importance of World Lung Day

Healthy lungs are essential for supplying oxygen to the body and removing carbon dioxide. Poor lung health can significantly affect quality of life and may contribute to disability and premature death.

Major respiratory diseases include:

• Asthma
• Chronic Obstructive Pulmonary Disease (COPD)
• Lung cancer
• Pneumonia
• Tuberculosis (TB)

Factors such as air pollution, tobacco smoking, respiratory infections and inadequate access to healthcare can negatively affect lung health.
