Continuous ground-sensor measurements tracking fine particulate matter and gas concentrations across Delhi, India.
Respiratory illness on prolonged exposure. Stay indoors and wear an N95 outside. Main pollutant is PM2.5.

Health effects are likely. Stay indoors and wear an N95 outside.
PM2.5 is 13.0× the WHO 24-hour guideline of 15 µg/m³.
Symptoms can escalate to intense wheezing, severe shortness of breath, chest tightness, and persistent coughing that may disrupt daily activities.
Precautionary guidance based on current AQI — not medical advice. Consult a doctor for persistent symptoms.
Estimate based on the Air Quality Life Index (AQLI) methodology: sustained PM2.5 above the WHO guideline of 5 µg/m³ reduces life expectancy by roughly one year per additional 10 µg/m³. This is a population-level estimate, not a personal prediction.
PM2.5 exposure converted to cigarette equivalents (Berkeley Earth)
Breathing today is equivalent to smoking 2.7 cigarettes.
22 µg/m³ for 24h ≈ 1 cigarette · Full day at this level: 2.7
