Heat therapy, also known as thermotherapy, has long been recognized for its effectiveness in managing pain and discomfort. The warmth from an electric heating pad increases blood flow to the affected area, which helps to deliver essential nutrients and oxygen to tired muscles. This enhanced circulation can aid in the healing process, reduce inflammation, and eliminate toxins from the body. Additionally, heat therapy can effectively reduce muscle spasms and promote relaxation, allowing users to experience significant relief from stress and tension.
