On erage, adults take 12–20 breaths per minute.

The air we breathe contains much more than vital oxygen — it comprises toxins and particulate matter (PM), high levels of which can harm health.

Poor air quality is exacerbated daily by multiple pollutants, which could increase the risks of health concerns ranging from heart disease to COPD, cancer, and even dementia. Unhealthy air quality is also associated with premature death.

We might not give the air we’re breathing much thought until we see noticeable changes in the air around us, such as during wildfire season, when the sky turns burnt orange and the Air Quality Index (AQI) reaches dangerously high levels.

“Many people may not think about the fact that air that looks clean (has good visibility) still contains pollutants that are harmful to health,” said Shahir Masri, ScD, a specialist in air pollution exposure at the Department of Environmental & Occupational Health at the University of California, Irvine.

If you’re concerned about the health effects of air pollution, it’s important to understand how to protect yourself.
