Cellphone Noise Can Startle a Fetus.
A small study indicates that sounds emitted by cellphones carried by pregnant women can disrupt the sleep and wake cycles of their unborn fetuses. What isn’t clear from the study is whether or not being repeatedly startled by the beeping and vibration of cellphones has any effect on fetal health or pregnancy outcomes. Study co-author Dr. Boris Petrikovsky comments, “So we now recommend that women not carry cell phones… in close proximity to their baby… They should put it in their chest pocket or bag. The further away it is from the baby, the less chance the baby will be affected.”
