Expert Comment: How Wildfires Affect Health and What Can Be Done

Wildfires across Europe, the U.S., and Canada this summer have created significant health hazards for millions of people.

Vulnerable populations including children, elderly individuals, and those with pre-existing health conditions face heightened risks. Understanding wildfire health impacts and implementing protective measures—such as monitoring air quality, using appropriate masks, and limiting outdoor exposure—are essential strategies to safeguard public health during fire season.
