Impact & Risks

The health risks from wildfire smoke are severe and widespread. Vulnerable populations, including children, pregnant women, and the elderly, face heightened risks of respiratory and cardiovascular issues. Studies show that prolonged exposure to smoke particles contributes to nearly 677,745 global deaths annually, with 39% of these affecting children under age five. In the U.S., wildfire smoke has been linked to an average of 24,100 deaths annually between 2006 and 2020. Immediate health impacts include asthma exacerbations, pneumonia, and mental health issues, while long-term exposure increases the risk of cancer and dementia. (Source: AP News)
