The worsening air quality in Delhi poses severe health risks, particularly for individuals with pre-existing conditions such as asthma, bronchitis, and chronic obstructive pulmonary disease (COPD). Prolonged exposure to PM2.5 and PM10 can lead to restricted blood vessels, elevated blood pressure, and increased risks of heart attacks and strokes. Vulnerable groups, including children, the elderly, and those with weakened immune systems, are at heightened risk of respiratory and cardiovascular complications.
