PROBLEM TO BE SOLVED: To accurately determine REM sleep of a subject of measurement without giving any burden on the subject of measurement.
SOLUTION: When an increase rate of a median value of a heart rate of a subject of measurement every first period is equal to a prescribed threshold or larger, it is determined that a first REM sleep period start and, when a reduction rate of the median value of the heart rate every first period decreases, termination of the first REM sleep period is determined. Frequency analysis of body motion of the subject of measurement is performed every second period, a plurality of decision trees making determination of REM sleep are generated by mechanical learning in data analysis whose frequency is analyzed, and it is determined that a second period is a second REM sleep period according to decision by majority about whether or not it is the REM sleep obtained by the plurality of generated decision trees. According to a result of determination of the first and second REM sleep periods, determination processing of the REM sleep period is performed.
