Diwali Amid Smog: How to Breathe Easy This Festival

For millions in South Asia, especially northern India, Diwali celebrations are now overshadowed by the return of hazardous winter air pollution. This seasonal smog exacerbates existing air quality issues across the region, compounded by fireworks during the festival.

Experts emphasize simple yet effective steps to reduce exposure to harmful pollutants. Checking the local air quality index (AQI) before venturing outdoors is paramount, with readings of 401-500 indicating severe levels that can affect even healthy individuals. Delhi, for example, has experienced pollution levels significantly exceeding global guidelines.

Wearing a well-fitting N95 or N99 mask that covers the nose, mouth, and chin is recommended during periods of heavy pollution. These masks are designed to filter at least 95% of airborne particles. Additionally, using appropriately sized HEPA air purifiers indoors can significantly improve indoor air quality by filtering pollutants.

To celebrate more safely, alternatives to traditional fireworks are encouraged. Opting for electric lights and reducing smoky cooking can minimize indoor pollution. Public health experts stress that while personal precautions help, sustained government action on pollution sources is crucial for lasting protection.
