This page is showing an example — an adult with asthma, planning outdoor exercise in Anand Vihar. Fill in your own details and the advice becomes yours.

Done

We count outdoor exercise as hard effort and a commute as light. Minute for minute, that is about four times as much air.

AGE HEALTH CONDITION WHAT YOU ARE PLANNING WHERE YOU ARE

Fit: No condition that makes polluted air riskier for you than for an average adult.
Asthma: A long-term condition where the airways tighten and inflame. Fine particles and traffic gases are common triggers.
Heart condition: Any diagnosed heart or circulatory condition. Fine particles raise the short-term risk of angina and irregular heartbeats.
Pregnancy: Raises sensitivity to fine particles, which are linked to lower birth weight and preterm birth.
COPD: Chronic Obstructive Pulmonary Disease — long-term lung damage, usually from smoking or long exposure to smoke and dust, that narrows the airways and makes breathing harder. Polluted air can trigger a flare-up.

Stays in this session only — never logged.

The exertion part of this score comes from published breathing rates (US EPA, confidence rated medium). The health-condition and age parts are our own judgement, not a validated medical model. See how the score is worked out ›

104Moderate AQI · India's CPCB scale, from PM10 alone — PM2.5 was not reported here · 3:00 PM

PM2.5 -- µg/m³

PM10 · DOMINANT 106 µg/m³

Coarser dust particles under 10 micrometres — irritate the airways and eyes; includes road and construction dust.

Acceptable for most. Sensitive groups (asthma, heart/lung conditions, kids, seniors) should take it easy on heavy exertion.

The World Health Organization comparison is about the finest particles, and this station is not reporting them right now, so it is not shown. How this compares ›

What do these numbers mean? ›

The five-day outlook comes from the WAQI feed. This reading did not arrive with one, so there is none to show — a reading read from CPCB directly never carries a forecast. What do these numbers mean? ›
