Heat therapy is a well-established method for managing pain, particularly musculoskeletal discomfort. When applied to the skin, heat increases blood flow, which enhances circulation in the affected area. This boosts the delivery of essential nutrients and oxygen necessary for healing while aiding in the removal of metabolic waste, thereby reducing inflammation and stiffness. Additionally, the warmth helps to relax tense muscles and soothe weary joints, providing immediate comfort to those suffering from back pain.
