What activity is likely to improve lung health?

Engaging in moderate physical activity is known to significantly improve lung health. Physical activity stimulates the respiratory system and enhances the efficiency of lung function. When the body is active, it increases the demand for oxygen, which leads to deeper and more frequent breathing. This can enhance the lungs' capacity and improve their ability to exchange oxygen and carbon dioxide, resulting in better overall respiratory health.

Additionally, regular exercise can strengthen respiratory muscles, contribute to improved circulation, and lead to better endurance, further supporting lung function. It is also associated with numerous long-term benefits, such as reducing the risk of lung disease and respiratory issues.

In contrast, smoking cigarettes is detrimental to lung health, as it damages lung tissue and reduces lung function. Breathing exercises alone may provide some benefits but may not be as effective as engaging in physical activity that challenges and uses the whole respiratory system. Restricting exercise generally leads to deconditioning of the lungs and decreased health benefits.
