Abstract

A system (100) for inducing a subject (110) to fall asleep comprises a monitor (120) for monitoring heart rate and breathing rate of the subject (110), a coherence assessing device (130) coupled to the monitor (120) for assessing a degree of coherence between the heart rate and the breathing rate, and an output device (140, 150) coupled to the coherence assessing device (130). The output device (140, 150) may comprise a light pattern generator (140) for generating a light pattern (145) in view of the subject (110) based on the degree of coherence. The output device (140, 150) may alternatively or additionally comprise an instructing system (150) for instructing the subject on a breathing pattern, and wherein the instructions are given based on the degree of coherence.
