Heat therapy units are medical devices used to apply controlled heat to specific areas of the body to relieve pain, improve blood circulation, and relax muscles. This therapy, also known as thermotherapy, is commonly used in rehabilitation centers, hospitals, and physiotherapy clinics.

These units may deliver heat through various methods such as moist heat packs, infrared radiation, paraffin baths, or hydrocollators. The generated heat dilates blood vessels, which helps reduce stiffness, promote tissue healing, and decrease inflammation.

Heat therapy is effective in managing conditions like arthritis, muscle spasms, joint pain, and sports injuries. Advanced units allow precise temperature control and safety features to prevent burns or overheating. Regular use under professional supervision can significantly enhance patient recovery and comfort.
