Electric Blankets Increase Risk of Miscarriage

Electric blankets increase risk of miscarriage: study

Electric blankets warm you in winter and save on your power bills. Are they safe, too?

Unfortunately no, a recent study says, especially if you are pregnant.

Electric blankets and many other environmental sources such as power lines, wireless devices and networks generate extremely low frequency (ELF) electromagnetic fields, called non-ionizing radiation.

High exposure to non-ionizing radiation significantly raises the risk of miscarriage, according to the study by Kaiser Permanente published in Nature last week.

The study examined the effect of non-ionizing radiation from magnetic fields on 913 pregnant women by asking them to wear a small magnetic-field (MF) monitoring device while recording their regular activities for a day.

After controlling for other factors, researchers examined the rate of miscarriages after classifying participants into either a “low” or “high” non-ionizing radiation exposure level, with the “low” group comprising of women who faced less than 2.5 mG of exposure.

Results showed women in the higher exposure group had more than double the risk of miscarriage than women in the low group. About 24 percent miscarried in the higher exposure group while 10 percent did in the other, the study showed.

The miscarriage rate in the higher exposure group was also higher than the rate of the general population, which is around 10 to 15 percent.

“The study provides additional evidence that exposure to high MF levels in pregnancy is associated with increased risk of miscarriage. Four other studies published during the past 15 years that examined the relationship between high MF exposure and the risk of miscarriage also support this finding,” it said.
