The hazardous air quality poses significant health risks, particularly for individuals with lung or heart conditions, children, and older adults. The smoke contains fine particulate matter (PM2.5), which can penetrate deep into the lungs and bloodstream, potentially causing respiratory issues, inflammation, and exacerbating chronic conditions like diabetes and heart disease. The National Weather Service advises limiting outdoor activities and keeping windows closed to reduce exposure. While the smoke may slightly lower temperatures by blocking sunlight, the overall health risks remain severe.
