What affects air quality for runners in Delhi
Delhi is one of the world's most complex urban air-quality environments, shaped by transport emissions, industry, construction dust, and regional sources. Pollution can persist across large areas rather than isolated streets, especially during calm periods. Even short outdoor exposure on poor-air days may represent a meaningful health burden for vulnerable groups.
