A spritz of perfume may feel like such a minor chemical exposure compared to the pollutants elsewhere in our environment microplastics, air pollution, PFAS. But scientists and clinicians are increasingly raising alarm over a group of chemicals used in many personal care products: phthalates. Phthalates " found in popular perfumes, nail polishes and hair care products " have been linked to numerous adverse health outcomes: insulin resistance, cardiovascular disease and impaired neurodevelopment. A study published in JAMA Network Open found that higher urinary concentrations of phthalates from personal care products was linked to a 25 percent increased risk of hyperactivity problems among adolescents. Another study of the same cohort found that increased phthalate exposure was also associated with poorer performance in math. The concerns about childhood exposure to phthalates are high enough that in the United States, certain types of the chemical are banned in children's toys and items such as pacifiers and baby bottles. For Andrea Gore, a professor of pharmacology and toxicology at the University of Texas at Austin ... the harms are clear enough that she advises everyone to try to reduce their exposure, especially parents starting a family and those with young children. "I recommend avoiding added fragrances altogether " in perfumes, scented lotions and shampoos, even scented detergents and antiperspirants," she said.
