An application for a wearable heat and light emitting device has an array of light and heat emitting devices such as LEDS mounted on a circuit board and held within a sponge material. The array of LEDs is held against a portion of a persons body by a fastening device such as a belt. A controller provides a controlled amount of power to the LEDS such that the LEDS emit a therapeutic amount of heat and light for the treatment of pain. The heat and light emitting devices form a thin sheet for wearing against a portion of a persons body that experiences pain.
