ONLINE: We breathe without thinking, navigating tides and rivers of air without noticing. So what particles are carried in the air we breathe? We examine this question about the air we breathe while on land, over water — and during an airplane flight. To start, we discuss a science fiction story that raises questions about atmospheric layers, how particles get transported, and how and what we breathe. Next is a look at the world's blanket of air and its many layers as a conveyance and as a habitat. We can now classify the air particles in each breath and understand better what arrives from global, regional, local and indoor sources. This serves as a foundation for the current topics of epidemiology, air quality, national security, allergy season and indoor health. We close with best practices for how to live better in our humid temperate climate with its seasonal changes. This course is taught from the viewpoint of the atmosphere and its airborne particles, not that of health care. | Facilitated discussion.
