Heat also stimulates the sensory receptors in the skin, which means that applying heat to the lower back will decrease transmissions of pain signals to the brain and partially relieve the discomfort. There are several other significant benefits of this kind of natural back pain relief that make it so appealing. Compared to most therapies, heat therapy is quite inexpensive and in many circumstances it’s free such as taking a hot bath. Heat therapy is also easy to do. It can be done at home while relaxing, and portable heat wraps also make it an option while at work or in the car. Although heat therapy is commonly administered with hot packs and hydrotherapy, ultrasound is also considered a form of heat therapy. Basically, hot packs heat up affected body parts by the process of conduction, hydrotherapy heats by convection, and ultrasound heats tissues as the result of the transduction of sound waves to heat. Radiant heat, short-wave diathermy, and paraffin baths are also used on occasion to heat up troublesome body regions.
For many people, especially among athletes, this natural back pain relief works best when combined with other treatment methods, such as physical therapy and exercise. Relative to most medical treatments available, heat therapy is appealing to many people as it is a non-invasive and non-pharmaceutical form of lower back pain relief.
