There's a warning for pregnant women to limit their exposure to microwaves.

A new study finds that women with the highest levels of exposure to electromagnetic fields gave birth to children three times more likely to develop asthma.

And women with high levels of exposure were also twice as likely to have a miscarriage.

Anything that uses electricity generates low-frequency electromagnetic fields.
