Heating blankets operate on the principle of heat therapy, which has been used for centuries to relieve pain and promote healing. The application of heat to the body increases blood flow, which helps to ease muscle tension and reduce stiffness. For individuals suffering from back pain, a heating blanket can be the perfect solution for immediate relief. By wrapping oneself in a soft, warm layer, the heat penetrates deep into the muscles and tissues of the back, promoting relaxation and alleviating discomfort.
