India's Silent Killer: Air Pollution Steals Years of Life
12 Dec
Summary
- Air pollution significantly reduces life expectancy for nearly half of Indians.
- PM 2.5 exposure in Delhi can shorten life by over eight years.
- Air pollution contributed to nearly two million deaths in 2023 nationwide.
Air pollution in India has evolved into a pervasive public health crisis affecting all demographics and nearly every organ system. Dangerous PM 2.5 concentrations are now a year-round issue, not just a winter problem in the northern plains, increasingly impacting urban centers nationwide. This persistent pollution is reshaping disease patterns, hindering child development, and silently diminishing life expectancy across the country.
The health toll is immense, with almost 46% of Indians residing in regions experiencing reduced lifespans due to polluted air. In Delhi alone, current PM 2.5 exposure can cut life expectancy by over eight years compared to WHO standards. Nationwide, air pollution was linked to nearly two million deaths in 2023, predominantly from cardiovascular diseases, stroke, COPD, and diabetes, marking a 43% increase since 2000.
