Open any weather report for your area, and in addition to temperature and humidity levels, you'll also find the current outdoor air quality. But what about when you enter a school, an office building, a hospital, or a grocery store—how do you know what that building's air quality is?
What's contaminating our indoor air?, including COVID, flu, RSV, and measles, spread through airborne transmission, which occurs much more easily in indoor environments.
"But there are a lot of other things that are in the air too, that are really unhealthy for you," explains Gigi Gronvall, Ph.D., an associate professor of Environmental Health and Engineering and a senior scholar at the Center for Health Security. Indoor air quality can be polluted by a range of sources, including mold, radon, carbon dioxide, particulate matter, chemicals in cleaning products, off-gassing from
and furnishings, and even outdoor air pollution. In fact, the concentration of some pollutants indoors is two to five times higher than outdoors.in preventing the spread of COVID, and research shows that improved air filtration and ventilation can also increase employee performance and productivity as well as improve test scores and teacher retention rates.Lead to respiratory diseases, heart disease, and cancer.
"It's not something we should be ignoring," says Gronvall."If you breathe poor air, you're not going to do as well, you're not going to think as well."
