Can prenatal PFAS exposure cause maternal depression during or after pregnancy?

What's actually in it

PFAS are present in nonstick cookware, food packaging, stain-resistant fabrics, and drinking water. During and after pregnancy, mothers are exposed through daily use of these products. PFAS can affect the brain's chemistry, including systems that regulate mood, bonding, and caregiving behavior.

What the research says

A 2026 study in Toxicol Sci examined how perinatal PFAS exposure affects maternal behavior and mood. The researchers found that PFAS exposure impaired maternal care behavior and triggered depressive-like symptoms in the study. Mothers exposed to PFAS showed less nurturing behavior and more signs of anxiety and depression.

Maternal depression affects both the mother and baby. Mothers who are depressed may have trouble bonding with their baby, breastfeeding, and providing responsive care. The baby's emotional and brain development can suffer as a result.

If you're pregnant or postpartum, reducing PFAS exposure may help protect your mental health. Filter your water, avoid nonstick cookware, and choose uncoated food packaging. If you're experiencing mood changes, talk to your doctor.
