Scientists in Denmark conducted a study in which they examined prenatal and postnatal exposure to mobile phones and behavioural problems in children. The study was conducted on a group of women whose children were around seven-year-old. They were given a questionnaire regarding the health and behaviour of their children, and their history of past exposure to the phone. In the end, it was found that children of women who were more exposed to cell phones prenatally and postnatally were hyperactivity and had some behavioural issue.
But this is one study and it does not establish a strong link between mobile usage during pregnancy and developmental problems in children.
Here are a few things you can do:
-Use a hands-free kit to reduce the radiation near your head or body.
