Impact & Risks

The combination of high temperatures and wildfire smoke poses significant health risks, particularly for vulnerable populations such as the elderly, children, and individuals with pre-existing heart or lung conditions. Prolonged exposure to heat and poor air quality can lead to heat exhaustion, heat stroke, and respiratory issues. The smoke may cause burning eyes, runny noses, and aggravate chronic health conditions. Outdoor activities should be minimized, especially for those in sensitive groups.
