Wildfire smoke poses long-term health risks in homes after fires

Wildfire smoke can pose health risks that last for months after a fire. When wildfires burn homes, they release toxic chemicals from materials like plastics and electronics, which can linger in indoor air and surfaces. Research following the 2021 Marshall Fire in Colorado found elevated levels of harmful substances in homes. Many residents reported symptoms like headaches and respiratory issues even six months after the fire, with some still experiencing symptoms two years later. As wildfires become more common, it is important for residents of affected areas to take precautions before cleaning their homes. This includes addressing lingering smoke and ash to protect their health.
