In a small study of pregnant women, researchers found that exposure to endocrine-disrupting chemicals commonly found in plastics and products like lipstick, perfumes and lotions – also known as bisphenols (BPA) and phthalates – could contribute to postpartum depression.
The study, published in the Journal of Clinical Endocrinology & Metabolism, looked at 139 pregnant women and their levels of bisphenols and phthalates in their urine as well as their sex hormone levels in blood samples.
