Exposure to indoor air pollutants is known to increase the incidence of which health issue?

• A. Upper Respiratory Infection
• B. Allergies
• C. Asthma
• D. Pneumonia

Answer: (A)

Indoor air pollutants irritate the lining of the nose and throat and can inflame the airways, which weakens the respiratory system’s defenses. In young children, whose airways are smaller and still developing, this makes them more likely to develop infections such as the common cold and other upper respiratory infections. That direct link to URIs is why this health outcome is most commonly associated with indoor pollutant exposure. While pollutants can also worsen allergies or asthma and may contribute to more serious infections in some cases, the strongest, most consistent relationship described here is with upper respiratory infections. To reduce risk, emphasize good ventilation, minimize smoke exposure, control moisture to prevent mold, and choose low-VOC products.
