"ELECTRIC BLANKET EMF’S (60 Hz Electromagnetic Frequency Waves)
In the late 1980’s and early 1990’s, some scientists and others began to be concerned over the safety of electromagnetic fields (EMF’s). Various studies in that timeframe had raised concerns over the possibility that the EMF’s generated by power companies’ overhead transmission lines and some appliances could cause cancer especially in children. The United States government became involved and studied over 500 peer reviewed papers written on this potential problem. The National Research Council spent around 65 million dollars and finally stated that there was no conclusive evidence that residential EMF’s play any role in the development of cancer, in reproductive issues or in learning/behavioral issues. Nevertheless Sunbeam, which was then the only major United States manufacturer of electric blankets, altered the design of its products to reduce EMF’s. Redesigned blankets produced after 1992 had much weaker electrical fields than their predecessors. The argument over EMF’s has never gone away completely although very few scientists and medical experts continue to believe that they can cause problems."
If your back is humming because of EMF's I have to wonder, can that be good? Sunbeam needs to look at their design again because I don't think being able to run electric current through your body is a really good thing. Maybe I can use the blanket as a back up generator.
