A method of controlling oxygen inhaling through an involuntary action of a user, includes the steps of generating a yawning influence signal periodically; applying the yawning influence signal through a media to the user; and contagiously stimulating the user to generate a sense of yawn by means of reflex action. Therefore, the user is able to subconsciously increase the oxygen inhaling into the human being and the carbon dioxide exhaling therefrom by means of involuntary action.
