Smoke from the extensive fires in Georgia and Florida is now enveloping six states in the southeastern United States, leading to air quality warnings from South Carolina to Alabama and Tennessee. Medical experts caution that this smoke contains PM2.5 particulate matter—tiny particles that can evade the body’s respiratory defenses and enter the bloodstream, potentially causing heart attacks, strokes, and asthma episodes even with brief exposure. Young children, older adults, and individuals with existing respiratory or heart issues are at heightened risk. Air quality authorities are advising those in affected areas to remain indoors, keep their windows shut, utilize HEPA air purifiers, and refrain from outdoor physical activities.
