The health impact of post-Diwali pollution is severe, especially for vulnerable populations. Children, elderly individuals, and those with respiratory or cardiovascular conditions face heightened risks of asthma attacks, breathlessness, and other complications. Prolonged exposure to pollutants can also lead to cardiovascular issues, such as increased blood pressure and heart rhythm disturbances. Noise pollution from firecrackers further contributes to stress, sleep disturbances, and hearing problems. Additionally, environmental degradation from synthetic colours, plastic waste, and improper disposal of festive materials affects water bodies, soil, and urban sanitation systems.
