Unhealthy air quality resulting from wildfires can have adverse effects on people with health conditions like asthma and pulmonary disease, but what is less clear is how long-term exposure to smoky air impacts the health of the general public. "Everything you see in the literature is calling for more research into this," said Dr. John Mignone, a cardiologist at Swedish Medical Center. Mignone specializes in treating heart failure and said he notices when the Seattle area experiences hazy skies from wildfire smoke.
