Sleep feeling determination method and sleep feeling determination apparatus

摘要

PROBLEM TO BE SOLVED: To provide a technique for objectively quantitating sleep feeling.SOLUTION: A sleep feeling determination method comprises: a step S11 of acquiring δ wave data indicating time-variant transition of power of the δ wave included in a brain wave of a subject during sleep; a step S12 of acquiring autonomic nerve data indicating time-variant transition of activity of parasympathetic nerve of the subject during sleep; a step S13 of, based on the acquired δ wave data and the autonomic nerve data, calculating an index value, relating to the subject, of synchronization property between the δ wave power and activity of the parasympathetic nerve; and a step S14 of, based on the calculated index value of synchronization property, determining the sleep feeling of the subject.SELECTED DRAWING: Figure 1
