Pregnant women who suffer high levels of stress are more likely have daughters that hit puberty early, a first-of-its-kind study suggests.
First born daughters of these fraught mothers developed public hair, pimples and cognitive improvements earlier than those born to women who were relaxed.
Researchers at the University of California – Los Angeles (UCLA) followed more than 250 mothers and their children for 15 years, beginning during the moms’ first trimester of pregnancy.
