Electric Blanket Effects

Concerns about electromagnetic fields emitted by electric blankets spurred modifications. Newer blankets have not been found to pose a risk, although some safety concerns do apply to electric blankets, especially for infants and the elderly.

History

• In the 1920s, a blanket heated with electricity was invented by Dr. Sidney Russell for use with tuberculosis patients. The blankets later became luxury items with temperature controls.

Concerns

• In 1990, concern about electromagnetic fields (EMF) radiated by many appliances led manufacturers to use polarized plugs to reduce emissions. While the Food and Drug Administration declined to mandate warning labels, research had shown troubling correlations between EMF exposure and birth defects. Newer blankets are safer. In addition, the 2000 Nurses Study showed no association between electric blanket use and breast cancer.

Considerations

• While electric blankets save money on heating, they should be used with caution by the elderly and very young, who may not be able to adjust controls. Overheating is a concern for pregnant women in the first trimester of pregnancy when environmental exposure to heat sources should be avoided.

Prevention/Solution

• Clean blankets exactly as directed on labels. When using an electric blanket to warm a bed, turning the blanket off before getting in limits EMF exposure.

Warning

• Do not use electric blankets made before 1992. Replace old electric blankets and do not use if you are incontinent.
