Breaking: Late-pregnancy wildfire smoke exposure linked to autism risk, study finds
A new study suggests that wildfire smoke exposure during the final stages of pregnancy may be associated with a higher autism risk in children. The findings point to a link, not a proven cause, and researchers urge cautious interpretation.
Experts emphasize that observational studies cannot prove that smoke exposure causes autism. They note the importance of considering other factors that may influence outcomes.
What the study indicates
The research identifies a possible association between late-pregnancy wildfire smoke exposure and autism diagnoses later in childhood. The authors stress that the results are preliminary and require further validation.
context and caveats
As climate change fuels longer and more intense wildfire seasons, more communities face smoky air. Health authorities advise limiting exposure during pregnancy when air quality is poor, including staying indoors with filtered air and using masks where appropriate.

Evergreen insights
Researchers will continue to assess how air quality during pregnancy affects development, as wildfire events remain a growing public health concern. the findings highlight the broader need to reduce wildfire emissions and to shield vulnerable populations through improved air quality monitoring and guidance.
What it means for you
Expectant families should discuss air quality plans with healthcare providers, especially in regions prone to wildfires. Public health officials advocate for community measures to improve air quality and preparedness for smoke events.
