项目摘要

An experimental study and a field survey was conducted to clarify the physiological and subjective responses to the heat of people who made a self-judgment of being sensitive to the heat.1) An experimental studyThe subjects were 20 young women(21.3±0.6 year old) and divided into two groups, an HS group(being sensitive to the heat, n=12) and an NS group(being non-sensitive to the heat, n=8) due to self-judged. Skin temperatures at 7 sites, oral temperature, humidity between skin and clothes, thermal sensation and thermal comfort were measured during the experiments. The three test sessions were conducted for each subject : 60-min exposure at 28℃, 30℃, 32℃(50±10% RH) after 20-min baseline at 26±1℃(60±10% RH). The mean skin temperatures after 60-min exposure at 28℃were 33.6℃for the HS group and 33.2℃for the NS group, which differed significantly between the groups(P<0.01). The HS group tended to produce more sweat and sweat earlier than the NS group, but showing no significant differences … More . There were significant correlations between mean skin temperatures and comfort sensation in both groups. The regression coefficient of the HS group's regression line was bigger than that of the NS group's. The HS group tended to complain of thermal discomfort with increase in skin temperatures compared with the NS group.2) A field surveyA field survey of the thermal environment of subjects was performed at their homes in the summer, July and August. The subjects of this survey were divided into two groups of 10 young females(21 to 23 years), an HS group(sensitive to the heat) and an NS group(non-sensitive to the heat). The thermal conditions of each subject's house were measured every two minutes for a week, and skin temperatures of the subjects at 7 sites(forehead, chest, forearm, hand, thigh, calf, foot) were also measured using a radiation thermometer every one hour while they were at home. Thermal sensation and clothes worn were recorded at times of skin temperature measurements.The mean room temperatures for a neutral thermal sensation were 27.2℃for the HS group and 28.3℃for the NS group, showing a significant difference at P<0.05.There were significant relationships between mean skin temperatures and ambient temperatures in both groups. However, the mean skin temperature of 34oC, which is usually observed in neutral thermal conditions, was obtained at 31.2℃and 28.7℃of room temperature(RT) in the HS group and the NS group, respectively. Subjects in the HS group reported being "slightly sweaty" at 30.2℃of RT, which was 0.5℃significantly lower than that in the NS group(P<0.05). The clothes worn in houses were 0.27 clo in the HS group and 0.25 clo in the NS group, although this difference was not statistically significant.Subjects in the HS group were sensitive to the heat and obtained thermal comfort in cooler thermal conditions. They had a tendency to produce comfortable thermal conditions using air-conditioning even under the conditions of wearing light clothes in summer. Less

本研究采用实验研究和现场调查相结合的方法，探讨了自我判断为热敏感的人群对热的生理和主观反应（21.3±0.6岁）并分为两组，HS组热敏感组（n=12）和热不敏感组（n=8）。实验过程中测量了7个部位的皮肤温度、口腔温度、皮肤与衣服之间的湿度、热感觉和热舒适性。对每例受试者进行三次测试：在26±1℃（60±10% RH）下基线暴露20分钟后，在28℃、30℃、32℃（50 ± 10% RH）下暴露60分钟。28℃暴露60 min后，HS组平均皮温为33.6℃，NS组为33.2℃，两组间差异有显著性（P<0.01）。HS组比NS组有产生更多汗液和更早出汗的倾向，但没有显示出显著差异 ...更多信息 .两组的平均皮肤温度和舒适感之间存在显著相关性。HS组回归线的回归系数大于NS组。与NS组相比，HS组倾向于抱怨热不适，皮肤温度升高。2）现场调查在夏季、7月和8月，在受试者家中对受试者的热环境进行现场调查。该调查的受试者分为两组，每组10名年轻女性（21至23岁），HS组（对热敏感）和NS组（对热不敏感）。每两分钟测量每个受试者的房屋的热条件，持续一周，并且当受试者在家时，每一小时使用辐射温度计测量受试者在7个部位（前额、胸部、前臂、手、大腿、小腿、脚）的皮肤温度。测量皮肤温度时记录热感觉和穿的衣服，中性热感觉时的平均室温HS组为27.2℃，NS组为28.3℃，两组比较有显著性差异（P<0.05）。然而，HS组和NS组的平均皮肤温度分别在31.2℃和28.7℃的室温（RT）下达到34 ℃，这通常在中性热条件下观察到。HS组受试者在RT 30.2℃时报告“轻微出汗”，比NS组低0.5℃（P<0.05）。HS组和NS组在室内所穿的衣服分别为0.27 clo和0.25 clo，尽管这种差异在统计学上没有显著性。HS组的受试者对热敏感，并且在较冷的热条件下获得热舒适。他们有一种倾向，即使在夏天穿着轻薄的衣服的条件下，使用空调来产生舒适的热条件。少
