Thermoregulatory responses Seasonal difference Children Elderly Bathroom Lighting Odor EEG 住宅環境生理的評価室温におい

项目摘要

(1) Circulatory responses of the children to heat in winter are inferior to those in summer, although the sweating responses of the children are similar to those of the young adults in each season.(2) In this study, the water temperatures of baths varied from about 39℃ in summer to 42℃ in winter. We reported that higher water temperature during showering was preferred when body temperature was low. Higher water temperature in winter might be due not only to Japanese habits, but insufficient bathroom heating in winter. Lower room temperature and hotter bath water in winter may be the cause of accidents for the elderly, who have weak physiological functions and sensations.(3) The interaction of odor and air temperature on EEG was found at θwave (F7) right after air temperature change, especially air temperature decrease from 25℃ to 15℃. It suggests that the effect of odor on EEG might be dependent on the degree of air temperature.(4) The color temperature of bathroom lighting could change body temperature during and after bathing with a constant bathing water temperature in winter. It was concluded that the lighting of 800 lm and 3000K in bathroom should be appropriate in winter to keep body warm in a comfortable state.(5) The subjects felt cooler and less comfortable in 26V than in 26C. In 26F, they felt the same level of comfort as in 26C. Thermal comfort in 26F was higher than in 26F. The most thermal comfort was found in 28F. There is a possibility that fluctuated thermal control may be superior to constant control in maintaining a healthy and comfortable living environment.

(1)儿童各季节的出汗反应与青壮年相似，但冬季对高温的循环反应弱于夏季。(2)本研究中，浴池的水温从夏季的39℃到冬季的42℃不等。我们报告说，当体温较低时，洗澡时最好使用较高的水温。冬天水温较高可能不仅是因为日本人的习惯，也是因为冬天浴室供暖不足。室内温度较低，冬季洗澡水较热，可能是老年人生理功能和感觉较弱时发生意外的原因。(3)空气温度变化后，θ波(F7)即出现气味和气温的交互作用，尤其是气温从25℃下降到15℃。提示气味对脑电的影响可能与气温的高低有关。(4)在冬季恒定的沐浴水温下，浴室照明色温可以改变沐浴时和沐浴后的体温。得出结论：冬季浴室采光应以800lm和3000K为宜，以保持舒适的体温状态。(5)受试者在26V条件下比在26C条件下感到凉爽和不舒服。在26华氏度，他们感受到了与26摄氏度相同的舒适感。26F的热舒适性高于26F。28F温度下的热舒适性最好。在维持健康舒适的生活环境方面，波动温度控制有可能优于恒定温度控制。
