Which of the following can also contribute to the development of COPD?

Exposure to secondhand smoke is a significant contributing factor to the development of Chronic Obstructive Pulmonary Disease (COPD). Secondhand smoke contains a mixture of harmful chemicals and toxins, similar to those found in the smoke inhaled directly by smokers. Individuals who are exposed to secondhand smoke over time can experience damage to their lungs and airways, leading to symptoms consistent with COPD such as chronic cough, difficulty breathing, and reduced lung function.

Regular exposure to secondhand smoke can lead to inflammation and long-term changes in lung tissue, increasing the risk of developing COPD alongside other factors such as primary smoking and environmental pollutants. Therefore, recognizing the dangers of secondhand smoke is crucial in understanding one of the many risk factors for COPD.

In contrast, regular exercise, drinking adequate water, and maintaining a high-fiber diet are generally associated with improved health and well-being and do not contribute to the development of COPD. They play vital roles in enhancing lung function and overall respiratory health.
