Heat therapy is the use of heat to relax muscles, improve circulation, and alleviate pain. It works by increasing blood flow to the affected area, which helps reduce muscle tension, promote healing, and ease pain. Heat therapy is commonly used for chronic muscle pain, stiffness, and joint conditions such as arthritis.

Heat can be applied in various forms, including hot packs, heating pads, warm baths, or infrared heat lamps. The warmth encourages the relaxation of muscles and ligaments, increasing flexibility and reducing discomfort. It also helps improve tissue elasticity, making it useful for both injury rehabilitation and general muscle relaxation.

Heat therapy is particularly beneficial for relieving chronic pain and stiffness, making it an effective tool for rehabilitation and improving functional mobility.
