One of the primary uses of a heating pad is pain relief. Heat therapy is widely recognized for its efficacy in alleviating muscle tension, stiffness, and soreness. By increasing blood flow to the affected area, heat can relax tight muscles and promote healing. Common conditions that benefit from heating pads include back pain, neck pain, sore muscles, and menstrual cramps. Whether it’s after an intense workout or a long day at your desk, applying heat can significantly diminish discomfort.
