Exposure to chemicals found in many personal care products appears to be linked to early puberty in girls. In this study, researchers observed that when a woman had double the amount of phthalates, parabens, or triclosan in her blood during pregnancy, her daughter would experience signs of puberty one or more months earlier than her peers who had less chemical exposure while in utero. Study author Dr. Kim Harley comments, “[Our] findings are consistent with what we know about the endocrine-disrupting properties of these chemicals… So, although we are not ready to say that early life exposure to these chemicals causes earlier puberty in girls, we have enough evidence to be concerned.”
