The heat and ozone levels are particularly dangerous for young children, older adults, pregnant individuals, outdoor workers, and those with chronic respiratory or heart conditions. Prolonged exposure can lead to heat-related illnesses, including heat exhaustion and heat stroke, as well as respiratory issues caused by elevated ozone levels. Higher elevations are experiencing Major HeatRisk, which increases the likelihood of severe heat-related illnesses for those without proper hydration or cooling. Residents without air conditioning or those concerned about energy costs may face additional challenges in staying safe.
