Heat therapy, also known as thermotherapy, involves applying heat to the body to relieve pain and promote healing. It can be delivered through various methods, such as heating pads, warm baths, or hot packs. This therapy helps increase blood flow, relax muscles, and reduce stiffness, making it beneficial for conditions like arthritis and muscle strains. Heat therapy is often used in physical therapy settings and can be a simple, effective way to manage discomfort. It is important to use heat safely, avoiding excessive temperatures and applying it for limited durations to prevent burns or skin damage.
