As if the many amazing (and a few maybe not so amazing) changes being preggo wreaks upon your person wasn’t enough, here’s one more weird one for ya.
According to a new UK study, having a child can change your voice, lowering the pitch—right up until a year post-delivery.
Research has already confirmed that the female voice register rises during ovulation (an evolutionary indicator that seems to suggest men prefer the higher pitch—who knew!).
The study analysing pregnancy’s hormonal effect on voice scoured archives of interviews with women who were recorded before and during pregnancy, and once they’d given birth—up to 10 years after. After listening to 600 voice recordings, comparatively examined against age-matched controls, the team found that mothers’ “mean and minimum pitch” plummeted 14Hz postpartum, and that, in general, women sounded more monotone shortly after becoming mums. (Nice.)
Researchers expectedly hypothesise the dramatic drop of hormones that occurs after childbirth as the key cause; although they admit another culprit may be to blame, too: good ol’ exhaustion. (Sadly, the latter reason is pretty hard to argue with.)
