BONUS - Another Air Quality Emergency in the US—2020 Wildfire Episode Re-release

With huge parts of the eastern seaboard covered in a thick hazy smoke from Canadian wildfires, we're re-releasing an episode from September 2020 with air pollution expert Dr. Kirsten Koehler.  In this episode, Dr. Koehler and Dr. Josh Sharfstein discussed how the massive West Coast forest fires raging at the time were affecting people's health. Their conversation about particulate matter and its impacts on respiratory health, and how to protect yourself, is just as relevant today in yet another air quality emergency.
