Scientists have studied the benefits of using air filters to reduce exposure to air pollution during pregnancy and evaluated its effect on children’s intelligence.
They found that infants born to mothers who used air purifiers had an average full-scale intelligence quotient (FSIQ) of 2.8 points higher than infants born to mothers who did not use air purifiers during pregnancy.
“These results, combined with data from previous studies, suggest that air pollution poses a threat to brain development,” the authors said.
Children in the purging group also had significantly higher verbal comprehension scores. The study suggests that a child’s verbal skills may be particularly sensitive to the effects of air pollution.
