The concept of using heat for therapeutic purposes dates back thousands of years. However, the modern electric heating pad emerged in the early 20th century, with significant advancements in technology making them safer and more effective. Initially, these pads were simple devices consisting of a fabric cover with electric coils inside, designed to generate and distribute heat. Over time, technological improvements have led to the introduction of features such as automatic shut-off, adjustable temperature settings, and even moisture-enhancing capabilities.
