Are bisphenols and phthalates in pregnancy linked to baby breathing problems?
Yes. Higher prenatal phthalates track with more wheezing, coughing, and asthma in young kids.
What's actually in it
Pregnant women breathe, eat, and absorb phthalates from soft plastics, fragranced lotions, and food packaging. The chemicals cross the placenta and reach the baby's developing lungs. Bisphenols do the same.
Babies in the womb during the lung-building weeks are most sensitive.
What the research says
A 2026 study in Environ Int pooled data from European child cohorts and tracked phthalates in pregnancy with kids' breathing scores from infancy to adolescence. Higher fetal phthalate exposure tracked with more wheezing, coughing, and asthma diagnoses. The link held across multiple studies.
Common phthalates linked to the worst scores were the kind that shows up in fragrance, soft plastic toys, and PVC flooring.
For pregnancy, switch to fragrance-free personal care, store food in glass, and avoid PVC vinyl flooring renovations during pregnancy. Use steel water bottles. Skip air fresheners and plug-in scents.
