Exposure to air pollution has serious consequences for children's cognitive development and overall brain health. Fine particles and other harmful pollutants threaten the respiratory system and neural growth, especially in children whose brains are still developing. Studies link pollution exposure to impaired cognitive functions, memory, attention span, and behavior. Researchers from the University of Oregon have voiced deep concern about the harmful effects of air pollution on children's brain development. “We are worried about how air pollution can hinder brain growth in children,” the scientists said.
