The Maharashtra health department has issued an advisory urging people to avoid outdoor morning and late evening walks, running, jogging, and physical exercise when the air quality index (AQI) turns “poor to severe”. The advisory highlights the risks posed to vulnerable groups such as children, the elderly, pregnant women, and those with pre-existing respiratory and cardiovascular illnesses. It also emphasizes the importance of avoiding exposure to air pollution for individuals with underlying medical conditions. The advisory provides guidelines on ventilation and suggests surveillance and monitoring measures to track air pollution-related illnesses.
