摘要
In a sleep quality estimation device, a respiration sensor detects the respiratory waveform of a subject. A sleep stage estimation unit estimates the sleep stage of the subject during sleep based on the respiratory waveform detected by the respiration sensor. In a sleep rhythm model database, models associated with the appearance probability of δ-wave for the sleep stage during sleep are recorded. A sleep quality estimation unit estimates the appearance time of δ-wave of the subject during sleep based on the sleep stage of the subject estimated by the sleep stage estimation unit and the models associated with the appearance probability of δ-wave for the sleep stage recorded in the sleep rhythm model database, and estimates the sleep quality of the subject based on the appearance time of δ-wave.
