It has been well known that far infrared rays radiated from ceramics fiber has thermal effect on humans. This study aimed to investigate if the fabric containing the ceramics fiber, with which the seat and back of chair (FIR) was covered, improve the problems of office workers such as neck - shoulder stiffness and cold sensation of the limbs as compared with non-ceramic fiber chair (BLANK). Ten healty male students (22.31±1.1year-old) volunteered for the study. The decrement of skin temperatures of the dorsal hand and foot at FIR was decreased. The activity of frontal muscle kept a resting level at FIR during mental work, but increased at BLANK and the enhancement of arousal level above optimum was also estimated from the increase in the inclination angle of the trunk at BLANK. It was suggested that FIR might keep the arousal level moderate and improve cold sensation of limbs.

The purposes of the present study were to observe the thermoregulatory responses from view points of sex difference, seasonal difference between winter and summer, and susceptibility to the heat (atugari) and the cold (samugari). The subjects were 13 females (20.5±0.5yrs, 159.2±6.4cm, 52.1±6.9kg) and 16 males (20.8±1.6yrs, 172.8±4.5cm, 61.6±6.3kg). They put on shorts or underpants, T-shirts and short pants. In the evening, the climatic chamber was controlled at 24℃ RH50%, the temperature increased to 29℃ over 60 minutes gradually. The subjects kept the sitting position. Measurement items were oral temperature, skin temperature, body weight, heart rate, blood pressure and subjective sensations. We determined atugari and samugari according to the subjective sensations of whole body during exposure. The main results were as follows. (1) The classification of atugari and samugari by self judgment did not always agree with the results of exposure experiments, (2) The skin temperatures were winter > summer in the body stem area and winter < summer in the peripheral area in male and female. (3) The skin temperatures were male < female in the body stem area and male > female in the limbs area. (4) Males felt warm in winter than in summer, and they felt warm than females in winter. (5) The values of subjective sensation were atugari > samugari generally. We guessed that the evening exposure produced these phenomena.

「朝食摂取トリプトファンを原料に,天然抗うつ剤のセロトニンが午前中合成され,精神衛生が改善,更にセロトニンは夜間入眠物質メラトニンに変換され,入眠や睡眠の質の改善をもたらす.」という理論的背景を基に「早寝、早起き、朝ごはんで3つのお得!」リーフレットシリーズを作成,幼児、中学生、大学生を対象とした,5種類の介入実験の結果,何れも朝型化や睡眠健康・精神衛生の向上をもたらすのに概ね有効であった.

本研究では光、温度、重力の各ストレスが及ぼす生理反応への影響から現代生活における適応性を評価した。その結果以下のことがわかった;1)朝の十分な光曝露と夜の電球色照明の選択は、概日リズムを調整し夜型化を抑制する。2)身体の運動不足や冬季暖房の慢性的利用は基礎代謝量を低下させ、耐寒性、耐暑性を低下させる。身体的運動はこれらの低下を向上させる。3)立ちくらみ頻度は夜型に多く、夜型は重力負荷に対する心拍応答が大きく直立耐性を低下させる。
