Do you use blankets over an electric blankets?

no. r u kidding me!!

Yes my wife and I do use an electric blanket with one or two other blankets. We have for years. We are very safety and health minded, so our process is to turn on the blanket 2-3 hours before we go to bed, then turn it off so we are not exposed to the normal EMF radiation from any electric current. We do not have the blanket on when we are not home to monitor it. We are mindful to never fold or bend the internal resistance wiring.
