PROBLEM TO BE SOLVED: To improve accuracy of estimation of a human state.SOLUTION: A human state estimation method for estimating a human state which is a state of a human is configured to: acquire (S101) a warm/cold sense index indicating a warm/cold sense of a human in a regulated range； determine (S102) whether or not the acquired warm/cold sense index is in a prescribed range of the regulated range； and estimate (S103) the human state, based on a physiological amount which is acquired when it is determined that the acquired warm/cold sense index is in the prescribed range, and in which activity of an autonomic nerve system is reflected.SELECTED DRAWING: Figure 11【課題】人状態の推定の精度を向上する。【解決手段】人の状態である人状態を推定する人状態推定方法は、人の推定された温冷感を規定範囲内で示す温冷感指標を取得し（Ｓ１０１）、取得した温冷感指標が、規定範囲のうちの所定範囲内であるか否かを判定し（Ｓ１０２）、取得した温冷感指標が所定範囲内であると判定されたときに取得した生理量であって、人の自律神経の活動が反映された生理量に基づいて人状態を推定する（Ｓ１０３）。【選択図】図１１
