The wildfire smoke poses significant health risks, particularly for sensitive groups such as individuals with heart or lung conditions, older adults, young children, and outdoor workers. Fine particulate matter in the smoke can penetrate deep into the lungs and bloodstream, potentially causing cardiovascular and respiratory issues. Areas near Boise, Idaho, and parts of Oregon and Idaho are experiencing the most severe air quality impacts, with conditions ranging from 'unhealthy' to 'very unhealthy.' While some smoke has reached the Midwest and southern states, it is expected to remain high in the atmosphere, reducing its impact on ground-level air quality.
