High air pollution levels can trigger which health conditions?

• A. Respiratory diseases
• B. Cardiovascular diseases
• C. Asthma exacerbations
• D. All of the above

Answer: (D)

When air quality is poor, pollutants affect both the lungs and the heart. Fine particles (PM2.5) and other irritants penetrate deep into the airways, causing inflammation and airway hyperreactivity that can worsen chronic respiratory diseases and trigger asthma symptoms. At the same time, these pollutants promote systemic inflammation and oxidative stress, which can destabilize the cardiovascular system and raise the risk of heart attacks, strokes, and other heart-related events. Because high pollution can provoke respiratory problems, asthma exacerbations, and cardiovascular issues, the option that includes all of these outcomes is the best choice.
