PROBLEM TO BE SOLVED: To provide a sleep state evaluation device and so on capable of, by a simple method, properly detecting a sleep state of a sleeper (a subject to be measured), determining and evaluating the sleep state and a life rhythm based on the sleep state, and appropriately outputting advice to improve the sleep state.SOLUTION: A sleep state indicating at least states of bed-leaving, sleep, and awakening is input as a state of a subject to be measured. The sleep state at night is evaluated for each of predetermined evaluation items on the basis of the inputted sleep state, and a sleep state evaluation score is calculated. A life rhythm is evaluated for each of predetermined evaluation items on the basis of the input sleep state, and a life rhythm evaluation score is calculated. On the basis of the sleep state evaluation score and the life rhythm evaluation score, an evaluation report is output.COPYRIGHT: (C)2013,JPO&INPIT【課題】簡易な方法で、就寝者(被測定者)の睡眠状態を適切に検出し、睡眠状態と、睡眠状態に基づく生活リズムを判定評価し、睡眠状態を改善するアドバイスを適切に出力可能な睡眠状態評価装置等を提供すること。【解決手段】少なくとも被測定者の状態として離床、睡眠及び覚醒の状態を示す睡眠状態を入力し、入力された睡眠状態に基づいて所定の評価項目毎に夜間の睡眠状態を評価して睡眠状態評価点数を算出し、入力された睡眠状態に基づいて所定の評価項目毎に生活リズムを評価して生活リズム評価点数を算出し、睡眠状態評価点数と、生活リズム評価点数とに基づいて、評価レポートを出力する。【選択図】図4
