The post-Diwali smog can lead to respiratory symptoms such as throat irritation, coughing, wheezing, and breathlessness. People with asthma, COPD, or heart disease may experience severe flare-ups requiring medical attention. Children and the elderly are especially vulnerable due to their weaker respiratory systems. Prolonged exposure to high pollution levels can also increase the risk of heart attacks, strokes, and long-term respiratory illnesses. Outdoor workers, such as street vendors and drivers, face heightened exposure and risks.
