A laugh counter is provided to count laughs by measuring/storing a sound level, vibration, and a temperature change when a user laughs out, and increasing the count if measurement is over a stored value whenever the user laughs out. The laugh counter includes a sound sensor(102) detecting a sound of the laugh, a vibration sensor(104) detecting the vibration of the user, a temperature sensor(106) detecting the temperature change, a memory(114), a processor(110), setting buttons(108), and an LCD(112). The LCD displays the set sound level, vibration frequency, and temperature change, a setting date, and the count whenever the user laughs out. An initial setting routine sets the sound level, the vibration frequency, and the temperature change of the user, and the setting date, and set the counter to zero. A counting routine increases the count by one and displays the count to the LCD whenever the set sound level, vibration frequency, and temperature change are satisfied at the same time.
