Recent studies suggest that wildfire smoke can affect more than just the lungs—it may reach the brain as well. Tiny particles from smoke can enter the bloodstream and trigger inflammation, potentially impacting cognitive function and neurological health. Prolonged exposure increases risks, highlighting the importance of protective measures like masks, air purifiers, and staying indoors during heavy smoke events. Wildfire smoke is a complex mixture of gases and fine particulate matter produced when organic matter burns. These particles, especially those smaller than 2.5 micrometers (PM2.5), are particularly dangerous because they can penetrate deeply into the respiratory system and even enter the bloodstream.
