A Pavlovian conditioned reflex sleep induction kit includes at least one physiological sensor, wherein the at least one physiological sensor is configured to detect at least a physiological parameter of a user and transmit a detection signal to an automatically activated scent diffuser, wherein the automatically activated scent diffuser is configured to receive an electronic activation signal and to diffuse a scent as a function of the electronic activation signal, a control circuit configured to receive the detection signal from the at least one physiological sensor, to ascertain that the user is entering a hypnagogic state, and to transmit the electronic activation signal to the automatically activated scent diffuser, thereby conditioning the user to respond to subsequent sensing of the same scent. For later use, a user-activated scent diffuser is provided, that diffuses the same scent upon activation by a user, to thereby trigger the conditioned reflex to fall asleep.
