Heat therapy, or thermotherapy, is a time-tested method for managing pain and promoting healing. When heat is applied to an affected area, it increases blood flow, enhances tissue elasticity, and reduces muscle tension. The warmth relaxes stiff muscles and alleviates pain, making it particularly effective for chronic pain conditions like arthritis and muscle strains. A back heat pack that is designed to be worn with a strap allows users to maintain mobility while receiving consistent heat therapy, making it an excellent choice for those with active lifestyles.
