Wildfire smoke and extreme heat can occur together: Preparing for the combined health effects of a hot, smoky future

It’s well understood that exposure to either wildfire smoke or extreme heat poses a significant threat to health. For example, there is substantial evidence linking wildfire smoke to an increased risk of hospitalizations for lung or heart complications, with emerging evidence that exposure may also affect birth outcomes and cognitive function.
