An electric blanket is a blanket containing an integrated electric heating wire. There are several types; underblankets, overblankets, throws and blankets. An underblanket is electrically placed on the mattress and under the bottom sheet of the bed. This is the most common type in the UK and Commonwealth countries, where it is known by default as an "electric blanket"; in the US and Canada, where it's less common, it's called a heated electric mattress mattress. Electric overblanket is placed on top of the top bunk bed, and is the most common type in the US and Canada, where it is called an "electric blanket".

The electric blanket usually has a control unit that adjusts the amount of heat the blankets produce. Blankets for two-person beds often have separate controls for each side of the bed. Electric blankets can be used for pre-heating the bed before use or to keep occupants stay warm while in bed.

Some modern "low voltage" power blankets have thin carbon fiber cables and work on 12 to 24 volts.

Mekanisme

Just like a heating pad, an electric blanket uses an insulated wire or heating element that is inserted into a heated fabric when plugged in. The temperature control unit, located between the blanket and the electrical outlet, adjusts the amount of current entering into the heat element. in the blanket.

Some modern electric blankets use carbon fiber elements that are much smaller and conspicuous than older heating cables. Carbon fibers are also used as heating elements in many high-class heated car seats. Blankets can be purchased with rheostats that regulate heat by managing body heat and blanket temperature, ensuring a comfortable experience.

Security

Overheating

The new electric blanket has a termination mechanism to prevent blankets from overheating or burning. Older blankets (before about 2001) may not have a termination mechanism; users run the risk of overheating. Older blankets are considered a fire hazard.

Some electric blankets work at low voltage 12 to 24 volts, including those that connect to common household electrical outlets; in the US, such blankets are sold by Soft Heat, Serta, and Select Comfort. Such blankets also include a 12-volt blanket designed for use in cars; they tend to die automatically every 45 minutes or so.

Old or broken blankets concerning international fire safety officers. The use of such blankets is a concern because of the combination of heat, electricity, abundance of combustible bedding, and sleeping dwellers. In the United Kingdom, it is estimated that 5,000 fires per year are caused by damaged electrical blankets, of which 99% are believed to be caused by blankets of 10 years or more.

Electric blankets also present the risk of burns to those who can not feel pain or can not react to it. Individuals included in this group are small children, diabetics, and parents.

As with any heat source in the groin, the use of electric blankets can reduce fertility in men.

Cancer

There is no mechanism by which ELF (Very Low Frequency) -EMF (Electromagnetic Field) or radio frequency radiation can cause cancer has been identified. Unlike high-energy radiation (ionization), EMF in non-ionizing parts of the electromagnetic spectrum can not damage DNA or cells directly. Some scientists speculate that ELF-EMFs can cause cancer through other mechanisms, such as by reducing levels of the hormone melatonin. There is some evidence that melatonin can suppress the development of certain tumors.
