What To Do When Air Pollution Reaches Unhealthy Levels

In areas with UNHEALTHY-SENSITIVE (AQI of 101 to 150) air quality, sensitive or susceptible persons, such as those with heart or lung disease, should minimize outdoor activity.

In areas with UNHEALTHY (AQI of 151 to 200) air quality or an Ozone HEALTH ADVISORY Alert (AQI of 151 to 200 for 1-hour ozone), everyone should discontinue prolonged, vigorous outdoor exercise lasting longer than one hour. Examples of the kinds of outdoor activities that should be avoided are calisthenics, basketball, running, soccer, football, tennis, swimming laps, and water polo. Susceptible persons, such as those with heart or lung disease, should avoid outdoor activity entirely.

In areas with VERY UNHEALTHY (AQI of 201 or above) air quality or an Ozone STAGE-1 Alert (AQI of 201 or above for 1-hour ozone), everyone should discontinue all vigorous outdoor activities regardless of duration.

AQMD is the air pollution control agency for Orange County and major portions of Los Angeles, San Bernardino and Riverside counties.
