Pulmonary health refers to the well-being of the lungs and respiratory system. It involves the proper functioning of the airways, alveoli, and blood vessels that facilitate breathing and oxygen exchange. Maintaining good pulmonary health is essential for overall health, as it affects physical activity, energy levels, and the body's ability to fight infections. Common factors that impact pulmonary health include smoking, air pollution, and respiratory diseases like asthma and chronic obstructive pulmonary disease (COPD). Regular exercise, a balanced diet, and avoiding harmful substances can help improve lung function and reduce the risk of respiratory issues.
