What are electric blankets?

Electric blankets use grids of thin insulated wires for internally heat. Earlier used adjustable thermostats to control temperature, but modern blankets (after 1984) use rheostates. Rheostats measures not only the heat generated by the blanket, but also the body heat generated by the user. This results in more even heating and less hot places.

The history of these blankets is a bit murky. When electricity was first introduced into households around 1900, the future inventors would add an electric element of many common objects. The first electric blankets were bulky and extremely dangerous. Most people considered them curiosities, not legitimate consumer products. Few examples of early exist are intact.

only in the 1920s. Patients with tuberculosis would spend most of their time to recover outdoors in the fresh air, but temperatures would drop overnight. Began usesThese blankets to keep their patients warm while staying outside. Eventually they got to the consumer market. One thin one could replace several expensive cover leaves, insulating blankets and blankets. They could be placed on wheelchairs for greater comfort. Hot-natured sleepers could adjust his blanket without affecting his husband at the cold. Manufacturers offered many advantages of blankets, but one serious disadvantage remained.

Because wires built into electric blankets are powered by electricity, there has always been a risk of shock or fire. Manufacturers commonly warn against the abuse of blankets, but consumers themselves cannot always detect endangered wiring. The continuing use of Oldeplash R has led to significant problems with random fires and electric power plants. Many of the most dangerous models have already been induced, but some seniors or consumers with lowThermostats sold at the age of 80 continue to use thermostats sold by the income.

There were also suggestions that long -term exposure to an electric field could lead to cancer development. Research in this area is still ongoing, but lifestyle proponents without cancer indicate the restriction of the use of electric blankets. There are alternatives, including the use of heated water beds or modern isolated blankets that maintain much more body heat. Consumers who want to buy a newer model should look for a generous length of the power cord, an adjustable rheostat controller separately from the blanket and detailed safety instructions. Those selling in stores can be too old for safe use.
