What this air does to your body

3.1
cigarettes/day equivalent
Breathing today's PM2.5 (68 µg/m³) is roughly like smoking 3.1 cigarettes a day — Berkeley Earth's rule of thumb (22 µg/m³ ≈ 1 cigarette).
−6.2 yr
life-expectancy impact
If this level held all year, it would cut average life expectancy by about 6.2 years versus the WHO guideline (5 µg/m³), per the AQLI method.

About air quality in Chittoor

This page tracks the Chittoor Air Quality Index using measurements from Central Pollution Control Board (CPCB) monitoring stations, published through the Government of India's open-data portal. The AQI is a single number from 0 to 500 that summarises how polluted the air is and what it means for health, based on the concentrations of key pollutants — fine particulate matter (PM2.5), coarse particulate matter (PM10), nitrogen dioxide (NO₂), ground-level ozone (O₃), carbon monoxide (CO) and sulphur dioxide (SO₂).

Air quality in Chittoor changes through the day and across seasons. Levels are typically worse in the early morning and late evening when cooler, calmer air traps pollutants near the ground, and across North India they rise sharply in winter (roughly October to February) when temperature inversions, crop-residue burning and festival activity combine. Summer and the monsoon usually bring cleaner air as rain washes out particulates and stronger winds disperse them. Checking the current reading before outdoor exercise, a school run or a commute helps you decide whether to adjust timing, wear a mask, or keep windows closed.

We only display a number when a recent station reading exists — if you see "data updating", it means we are waiting on a fresh value rather than showing an estimate.
