Measurement is made about a necessary evaluation parameter of a subject, the parameter being variable due to sleep apnea of the subject. A body position of the subject is detected in terms of angle information. The parameter measurement and the body angle detection are executed at a predetermined sampling frequency. These data are stored in a storage. A sleep evaluation system includes: an evaluation parameter detector for measuring an evaluation parameter of a subject, a body position detector for detecting a body position of the subject in terms of angle information; a storage for storing measurement data acquired by the evaluation parameter detector and by the body position detector therein; and a controller for causing the evaluation parameter detector to measure the evaluation parameter, and causing the body position detector to measure a body angle of the subject at a predetermined sampling frequency to store the measurement data in the storage.
