Question: 1 / 400

How does smoking cessation benefit respiratory health?

Increases lung capacity

Improves lung function

Smoking cessation significantly improves lung function, which is crucial for overall respiratory health. When a person quits smoking, the lungs begin to repair themselves, and the cilia (tiny hair-like structures that help clear mucus and debris) start to regrow and function better. This repair process leads to improved airflow and reduced symptoms such as coughing and wheezing.

Moreover, the reduction in inflammation in the airways can enhance the effectiveness of the lungs in oxygen exchange, which is vital for endurance and physical activity levels. Over time, individuals who cease smoking can experience a notable decline in the risk of developing chronic obstructive pulmonary disease (COPD) and other lung-related health issues. Ultimately, improved lung function not only enhances quality of life but also significantly extends lifespan.
