How Many Breaths Do You Take Each Day?

It’s Air Quality Awareness Week!

Watching the news and the problems that some countries are having with high levels of air pollution makes me appreciate the Clean Air Act, which calls on EPA and the states to protect air quality through programs based on the latest science and technology. I am especially appreciative today, the first day of Air Quality Awareness Week.

When I joined EPA’s Office of Research and Development 16 years ago, I didn’t think much about the quality of the air I breathe. I took it for granted. It is an unlimited supply. I don’t have to pay a monthly bill for it. It is just there for the benefit of my body.

Then as I began to work with scientists and engineers conducting air research at EPA, I gained an appreciation for this precious resource.  Their research showed me why it is important to know what is in the air, how you can be exposed to any pollutants it contains, and what the related risks and health effects might be. I’ve also learned about their work on advancing control technologies to reduce air pollution. EPA scientists are working in all these areas to provide the science that can be used to protect air quality.

The average person takes between 17,280 and 23,040 breaths a day. That is a lot of breaths…and each one is an opportunity to put pollutants into your lungs and body and to increase health risks if you are exposed to air pollution. For example:

  • Research shows that air pollution is linked to health effects and disease, including heart disease and stroke. EPA is a partner in the Million Hearts initiative to educate the public, especially those with heart disease, about the dangers of air pollution to their health. You can learn more about air pollution and heart disease at www.epagov/healthyheart.
  • Air pollution can cause or worsen asthma. Extensive research links asthma to ozone, particle pollution and a host of common indoor environmental asthma triggers. Join EPA experts to discuss asthma and outdoor air pollution on a Twitter chat on May 1 at 2 p.m. (Eastern Time) on @EPALive. Use the hashtag #asthma.

Air quality awareness week is a good time to learn what you can do to protect your health and the health of your friends and family. Many resources are available to learn about air quality and how to protect your health. A good start is to use the Air Quality Index where you can get daily local air quality reports and information to protect your health from air pollution.

Scientists continue to investigate air quality to protect our health and the environment. I’m glad to be a small part of this effort. Learn more about what scientists are doing at www.epa.gov/airscience.
