The study’s lead author Anne Waldrop, MD, a maternal-fetal medicine subspecialist fellow at Stanford University in Palo Alto, Calif says, “some emerging evidence suggests that wildfire smoke could be worse for your health than other types of pollutants. So, even as we work to decrease other forms of air pollution, with wildfires becoming more frequent, more intense, and happening on a much larger scale, exposure to wildfire smoke is a serious public health problem, especially for vulnerable populations like pregnant people.”
