Wildfire smoke is more than just wood burning. Research shows a mix of chemicals can be released when human-made materials burn up.

The Mountain West has seen a record increase in wildfires over the past couple years, and even if a fire was not burning in the state, smoke from these fires drifted across the region. Now, new research is showing that exposure to wildfire smoke can have negative effects on the brain.

Researchers found that those wildfires increase the “occurrences of heavy precipitation rates by 38%” in our region, according to their work in the journal Proceedings of the National Academy of Sciences.
