Summary

This study looked at how breathing in simulated wildfire smoke for just one hour affects healthy adults. Researchers measured a blood marker called p-tau, which is linked to memory problems, and tested thinking skills before and after exposure. The goal was to see if short-term smoke exposure causes any immediate changes in the brain.
