Abstract
A system for inducing a subject to fall to sleep includes a light pattern generator for generating a time varying light pattern in view of the subject. Further, the system includes a breathing rate measuring unit for measuring a breathing frequency of the subject. In addition, the system includes a control unit connected to the breathing rate measuring unit and the light pattern generator, for controlling the light pattern generator such that the generated light pattern has a pattern frequency substantially between the measured breathing frequency and a pre-selected desired frequency.
