While originally heat is associated with the qualities of providing warmth, comfort and relaxation, heat is also used to provide relief from pain through thermotherapy, or what is commonly known as heat therapy. It involves exposing suffering body parts to high temperatures in order to enhance their flexibility and decrease stiffness. It can take various forms like hot water, heating pad, heat pack, hot cloth, infrared heat therapy and many others. The effectiveness of a particular therapy depends upon the concerned injury and the time scale that helps in deciding which form of therapy could be used to give quick relief. The therapeutic consequences of heat therapy include relief in pain and muscular spasms, reduced inflammation, increase in blood flow, decrease in joint stiffness, pain resulting from strains, over-exertions and in chronic injuries. It is also used for treatment of certain open skin injuries mostly along with antibiotics.
