What health issues are commonly linked to indoor air pollution?

Respiratory infections and allergies are commonly linked to indoor air pollution because many sources of indoor pollutants, such as mold, dust mites, pet dander, and tobacco smoke, can irritate the respiratory system. These irritants can exacerbate existing conditions like asthma and lead to respiratory infections, particularly in vulnerable populations such as children and the elderly. Poor indoor air quality can also trigger allergic reactions, causing symptoms such as sneezing, coughing, and difficulty breathing. Ensuring proper ventilation and reducing sources of pollution can significantly improve indoor air quality, thereby reducing the risk of these health issues.

Other health issues like digestive disorders and skin infections are not typically associated with indoor air quality. While cardiovascular diseases can be influenced by air pollutants, the direct connection to indoor air specifically is less pronounced than with respiratory problems.
