If you're a pregnant mother its probably a good idea to stay away from the cell phone and microwave as much as possible.
A new study finds a link between women who are exposed to high magnetic field levels during pregnancy and overweight children.
Both Microwaves and cell phones give off magnetic fields.
Researchers followed more than 700 children for 13 years and found those exposed to the highest magnetic fields before they were born were 69 percent more likely to be obese or overweight.
