Which lifestyle factor can worsen asthma and other upper respiratory conditions?

• A. Regular exercise in clean air
• B. Exposure to environmental pollutants
• C. A balanced diet rich in omega-3 fatty acids
• D. Staying hydrated

Answer: (B)

Exposure to environmental pollutants is a common trigger that aggravates asthma and other upper airway conditions by irritating the airways and promoting inflammation. When pollutants like smoke, car exhaust, industrial fumes, or strong chemicals reach the respiratory tract, they can cause the airway lining to swell, increase mucus production, and make the smooth muscles around the airways more prone to constriction. This combination narrows the airways and heightens sensitivity, leading to more frequent or severe symptoms such as coughing, wheezing, and shortness of breath.

In contrast, regularly exercising in clean air tends to improve lung function and overall airway health, not worsen it. A diet rich in omega-3 fatty acids can have anti-inflammatory effects that may help reduce airway inflammation, and staying well hydrated supports mucus clearance rather than worsening symptoms. So the factor that can worsen asthma and other upper respiratory conditions is exposure to environmental pollutants.
