Anti-inflammatory foods like fatty fish and nuts reduce airway inflammation. These foods support natural healing processes and boost lung capacity.

Prevent lung disease with regular cardiovascular exercise. Swimming, cycling, and walking improve lung function. Start slowly and increase intensity gradually.
