Wildfire smoke may cloud your thinking, new study shows

This study looked at how breathing in wildfire smoke for just one hour affects healthy adults' brains. Researchers measured a blood marker called p-tau, which is linked to memory and thinking problems. Twelve healthy people aged 18-40 took part, each having two visits: one breathing clean air and one breathing simulated wildfire smoke. They gave blood samples and did memory tests before and after each exposure to see if the smoke caused any changes.
