A New Reality of Childhood
For generations, summer in Montana meant long days outdoors. Children spent afternoons riding bikes through quiet neighborhoods, swimming in lakes and rivers, hiking on forest trails, and playing baseball after sunset. Families planned camping trips months in advance, checking to make sure they had all the necessary gear to sleep in fresh air under clear skies.
Today, many parents check the Environmental Protection Agency's Air Quality Index before deciding whether their children can play outside.
What's Happening
As the wildfire season becomes longer and more severe in the American West, smoky skies have become an increasingly familiar part of summer. In Montana, where wildfires have always been part of the landscape, summer now includes days or even weeks when children are advised to stay indoors because the outside air is unhealthy.
Scientists have documented the growing health risks of wildfire smoke, particularly for children, whose lungs are still developing.
Why It Matters
Pediatricians and researchers say the consequences go beyond children's lungs. A 2024 UNICEF report found that wildfire smoke affects not only children's respiratory health but also their learning, mental well-being, and opportunities for play, warning that repeated exposure to smoke can shape childhood in lasting ways.
Repeated smoke events are changing children's daily routines, limiting opportunities for outdoor play and social interaction, and redefining how many families experience summer.
The Mechanism Behind It
Wildfire smoke contains tiny particles known as PM2.5, which can travel deep into the lungs and enter the bloodstream. Studies in the Journal of Exposure Science & Environmental Epidemiology have linked exposure to wildfire smoke with asthma attacks, respiratory infections, and emergency department visits, particularly among children.
Children face greater risks from wildfire smoke because their lungs are still developing, especially during the first years of life, and they breathe in more air relative to their body weight than adults.
Bigger Picture
Although Montana doesn't have state-level pediatric hospitalization data that directly links wildfire smoke to childhood illnesses, pediatricians say they routinely see more children with asthma attacks and other respiratory problems during smoke events.
National studies show increases in emergency department visits among children during periods of heavy wildfire smoke.
What's Next
As hotter summers, longer wildfire seasons, and more frequent smoke events become an expected part of life in western Montana, schools are being designed to protect children's health during climate emergencies, keeping classrooms cool during heatwaves, filtering out smoky air, and, when necessary, serving as clean-air shelters for surrounding communities.
This reality has inspired the Montana Climate-Ready Schools initiative. Missoula County Public Schools are working with partner organizations to redesign schools so they can better withstand the challenges of a changing climate.
