PURPOSE: A method for analyzing the degree of stress relief with a visual sense, an aural sense, and an audio-visual sense is provided to collect data for PPG(Photoplethysmography) and ECG(Electrocardiogram) in order to determine the method having a biggest effect on the stress relief and to provide the method for relieve stress with one of the visual sense, the aural sense, and the audio-visual sense. CONSTITUTION: A method for analyzing the degree of stress relief with a visual sense, an aural sense, and an audio-visual sense includes the following steps: a step(S10) of connecting an experimental sensor and an experimental electrode to a subject； a step(S30) of collecting a sensor signal and an electrode signal from the relaxation condition of the subject for a first hour predetermined against the subject； a step(S50) of providing a stress environment to the subject for a second hour predetermined against the subject； a step(S70) of collecting a sensor signal and an electrode signal from the stress condition of the subject； a step(S90) of providing at least one of a visual material, an aural material, and an audio-visual material to the subject in order to relieve stress for a third hour predetermined against the subject； a step(S110) of collecting a sensor signal and an electrode signal according to providing the materials for relieving the stress of the subject； and a step(S130) of analyzing the degrees of stress relief with the visual sense, the aural sense, and the audio-visual sense against the sensor signals and the electrode signals according to collected data, and storing corresponding analysis data.
