発明の名称 (英語) EVALUATION OF SLEEP STATE NEW
発明の概要(英語) The present invention addresses the problem of providing a means for detecting a sleep state, in particular, non-rapid eye movement sleep, with high accuracy and high reliability. Provided is a method for detecting non-rapid eye movement sleep, the method comprising: a step for generating time-series data on heartbeat intervals of the heart of a subject; a step for setting a window that has a predetermined time length and moves along the time axis of the time-series data, and performing, for each of a plurality of determination points on the time axis, spectral analysis on time-series data in the window including the determination point; a step for calculating, from the spectra of the windows, the degree of concentration of power of a heart rate variability high frequency component; and a step for determining whether the sleep state is non-rapid eye movement sleep on the basis of the calculated degree of concentration.
従来技術、競合技術の概要(英語) BACKGROUND ART
Due to the popularity of the wearable display, or a heart rate during the daily life data of body acceleration and is being accumulated as big data, such as sleep or physical activity from the quality of the development of a method for evaluating the health index of the growing needs.Therein, the heart rate from the acceleration data, time asleep and awake can be estimated to time, basic and essential element in the art, is a major problem of the development work.To this, the heart rate and body acceleration, heart rate variability of the change of the parasympathetic nervous index, the fall-asleep, the wake-up has been proposed is a method for estimating (for example see Non-Patent Document 1-4).
