Not only do they emit EMF radiation, but they also have harmful effects on humans. There are a lot of cases where house fires were associated with using an electric blanket. In some cases, the fires caused serious burns and, to some extent, even death, especially in the ‘90s.
When you keep the electric blanket on for too long, the wires inside the blanket may start to overheat and result in fires. Another reason for overwhelming wires is improper storage of the electric blanket. If you leave the blanket for too long in the socket without using it, it will result in overheating.
Folding the blanket can also make the wires bend and eventually break, affecting the even distribution of current throughout the blanket. This results in fires or overheating.
