An electric blanket is a type of bedding that uses an electrical heating system to provide warmth and comfort while sleeping. It typically consists of a thin insulating material, such as polyester or cotton, with wires embedded within it that carry an electric current to heat-producing elements (such as resistance wire coils) located throughout the blanket. When plugged in, these heating elements generate warmth by converting electrical energy into thermal energy through a process called Joule heating. Electric blankets can be used all year round and are especially popular during winter months to provide additional warmth while sleeping. They come in various sizes and styles to fit different bed types and preferences, and some models also feature advanced features such as temperature control or timers for convenience and energy efficiency.
