A radiant therapeutic wrist heating pad, which is not hot to the touch, provides substantial infrared radiation to a user's wrist to alleviate symptoms of carpal tunnel syndrome. It can be used for extended periods without feeling uncomfortable to the skin, while imparting deep therapeutic heat to the user's wrist. The heating pad is comprised of a radiant heat generating layer having a plane surface comprising means for radiating heat evenly from its surface, a pair of flexible electrically insulating and radiation permeable layers located adjacent and covering opposite sides of the layer, a thermal insulation layer disposed against and covering one of the electrically insulating layers, and a sealed radiation permeable envelope enclosing the entire heater. Preferably the flexible heat generating layer is comprised of a fiberglass material impregnated with a resistive material, which material provides a surface temperature, when current is conducted therethrough, which is no greater than about 54 degrees Celsius. Current limiting thermostats are provided to prevent energy and temperature spikes in the event that any of the electrical components are creased or bent. A stiffening element helps protect the electrical components, and also orients the user's hand with respect to the forearm so as to place the wrist in a therapeutic position.
