Dr. Jyoti Mishra personally knows how much stress can come with a wildfire. The associate director of the UC Climate Change and Mental Health Council and associate professor of psychiatry works at the University of California, San Diego. Her city isn’t currently experiencing wildfires, but her LA-based family has fled to her home.

“All our family from LA is here with us, and we’re happy they’ve made it,” Mishra said Thursday. “We’re hoping their home is safe up there, but we don’t know yet.”

Uncertainty about losing a home or a neighborhood is one factor, studies have showed, that can contribute to an increase in mental health problems among people who experience wildfires.
