Electric blankets are bedding items designed to provide warmth through built-in electrical heating elements. They typically come with adjustable heat settings, allowing users to control the temperature for comfort. Made from soft materials, they can be used on beds or couches and are often used during colder months. These blankets are powered by electricity and usually have a cord that plugs into a wall outlet. Safety features, such as automatic shut-off timers and overheat protection, are common to prevent accidents. Electric blankets can be beneficial for people with certain medical conditions, as they help alleviate muscle pain and improve circulation.
