An autonomic-nervous state judging device measures an autonomic-nervous index of a subject in sleep at predetermined time intervals. The autonomic-nervous state judging device sets a plurality of cycle frames of a predetermined length each including one sleep cycle, and a judging frame in a cycle frame at a predetermined position. The autonomic-nervous state judging device specifies state of autonomic nervous system in the judging frame based on the autonomic-nervous index, and detects timing of a change in the state of the autonomic nervous system.
