The present invention discloses a method for detecting temple hot spot temperature of a live body. Firstly, an infrared thermometer is used to continuously scan a temple of testees forehead to obtain a plurality of measured infrared signals. Next, the measured infrared signals are sequenced from a greatest to a smallest measured infrared signal. Two output infrared signals closest to the greatest measured infrared signal are selected from the sequenced infrared signals. An average signal value is worked out from the selected infrared signals. Then, the average signal value is converted into a temple hot spot temperature of the testees forehead. Thereby, not only the test result is more precise, but also the testee can learn the test result sooner.
