What type of therapy involves the application of heat or cold to relieve pain?

Thermal therapy is a form of treatment that utilizes the application of heat or cold to manage pain effectively. This method is based on the principle that heat can increase blood flow and promote healing, while cold can reduce inflammation and numb sharp pain sensations. In clinical settings, thermal therapy is commonly employed in rehabilitation and pain management practices to address various conditions, such as muscle strains, arthritis, and post-surgical pain.

Heat therapy, or thermotherapy, can involve methods such as warm compresses, heating pads, or warm baths, which can help relax muscles and alleviate stiffness. Cold therapy, or cryotherapy, often includes ice packs or cold compresses, helping to diminish swelling and provide a numbing effect, which is particularly beneficial shortly after an injury.
