Safety Electric Concerns - Save with Coupon Codes

Beginning in 1990, electric blanket manufacturers began responding to controversy over the safety of electromagnetic fields in bed. Various studies had raised concerns over the extremely low frequency electric and magnetic fields emanating from electronic devices, including electric blankets. One study released in 1990 in ‘The American Journal of Epidemiology’ found an increased risk of brain tumors and childhood leukemia in children whose mothers had used electric blankets while pregnant. Though other studies tracing a cancer link to electric blanket bed use had negative or conflicting results, the reports were alarming enough to prompt a group of United States congressmen to ask that the blankets be labelled hazardous to women and children. A panel appointed by the Food and Drug Administration concluded that there was not enough evidence to warrant regulation of electric blankets, but research did show some problems. Some brands of electric blankets produced greater electric fields than others. If the blanket's plug was not polarized then it could be plugged in the wrong way producing a significant electric field near sleepers’ bed even when turned off. Though there was no conclusive evidence that the electric fields produced by electric blankets were harmful, the major United States manufacturers altered their products. The major maker of the wiring for electric blankets came up with a new system that used parallel wires holding current flowing in opposite directions. This effectively cancelled out most of the extremely low frequency field. The redesigned blankets produced after 1992 had much weaker electrical fields than their predecessors and safe enough to use in bed. After this, the subject of electric blanket safety faded away.
