Perceptional Mechanisms of the Humid and Wet Sensation of the Human Skin and the Effect of the Sensation on the Central and Autonomic Nervous Systems

湿感和湿感的评价在服装舒适性研究中具有重要意义。本研究的目的是为了更好地了解人体功能的湿和湿感觉的机制。本研究的另一个目的是确定由服装引起的潮湿和潮湿感觉对中枢和自主神经系统的影响。结果表明：（1）在人体与环境建立热平衡所需的蒸发热传递和皮肤表面的真实的蒸发热损失是造成人体整体湿感的主要因素;（2）采用胶囊法对皮肤施加局部湿刺激对局部湿感无影响。影响局部湿度和湿感的最重要因素是皮肤蒸发引起的皮肤温度变化， 关于我们 3）制作了由聚乙烯薄膜制成的具有不同尺寸孔的实验服，并通过KES系统和出汗暖体假人评估了实验服的物理性能，特别是热性能和蒸发热性能。4）对穿着实验服的受试者的心率波动进行功率谱分析，HF /（HF+LF）随衣服内湿度的增加而降低。5）EEG的α波频率百分比，其指示对象的放松，随衣服内湿度的增加而降低。6）作为内分泌反应的研究结果，唾液中分泌型免疫球蛋白A和皮质醇含量随衣内湿度的增加而增加，肾上腺素含量随衣内湿度的增加而减少，提示衣内湿度对唾液中分泌型免疫球蛋白A和皮质醇含量的影响不仅对心理感觉，而且对生理条件、自主神经系统和中枢神经系统都有很大影响。少

The evaluation of humid and wet sensation is very important in studies aiming to assess clothing comfort. The present study was carried out in order to better understand the mechanism responsible for humid and wet sensation of the human body function. Another object of this study was to determine the effect of humid and wet sensation that was caused by the clothing on the central and autonomic nervous systems. The results were mainly summarized as follows.1) The main factors contributing to the general humidity sensation of the human body were the evaporative heat transfer required in establishing a heat balance between the human body and the environment, as well as the real evaporative heat loss from the skin surface2) Regional humid stimuli added to the skin by using capsule method had no effect on the regional humidity sensation. The most important factors which contributed to regional humidity and wet sensation were change in skin temperature through evaporation from the skin and t … More he tactile sensitivity to water on the skin.3) The experimental clothes made of polyethylene film with different size holes were made and the physical properties, especially the thermal and evaporative heat properties, were evaluated both by KES system and by a sweating thermal manikin.4) A power spectral analysis of heart rate fluctuation of the subject wearing the experimental clothes showed that an index of parasympathetic activity level, HF /(HF+LF), decreased with humidity inside clothes.5) Alpha waves frequency percentage of EEG, which indicated the relaxation of the subject, decreased with humidity inside clothes.6) As a result of investigation of the endocrine responses, Secretory immunoglobulin A and cortisol volume in saliva was increased and adrenalin was decreased with humidity inside clothes.All these results pointed out that the humidity caused by clothes greatly affected not only on the psychological sensation but also on the physiological conditions, autonomic and central nervous systems.
