Keeping Your Lungs
and Heart Safe: Use the Air Quality Index to Protect Against Poor Air Quality
You’re exposed to air contamination any time you breathe polluted
air. But when you exercise, work in the yard, or do other strenuous activities
that make you breathe harder and faster, you take more polluted air into
your lungs. Exposure to ozone and particle pollution is linked with a number
of significant health problems. Children, people with lung disease, older
adults and people with heart disease tend to be more vulnerable, depending
on the type of pollution in your community. And when pollution levels reach
high enough levels, the air can be unhealthy for everyone – especially
if you’re active outdoors.
You can help protect yourself simply by changing the time or intensity
of your exercise, yard work or other strenuous activities. Use the Air
Quality Index (AQI) and daily air quality forecasts to help you determine
when you need to make changes.
The AQI is a color-coded scale that tells you who needs to take steps
to reduce their exposure to ozone or particle pollution – and when.
If you have heart disease, for example, pay close attention when particle
pollution reaches “Code Orange” levels. If you have asthma,
you’ll want to pay attention at Code Orange for particle pollution
and for ozone. Local air quality forecasts are available at www.airnow.gov.
