Physio-Anthropological Study on Polymorphism of Physiological Responses to Artificial Environments

本研究旨在探讨人类对光、声、压力等环境因素反应的生理多态性。首先，我们检测了40名男性受试者人格类型(A型和B型)对认知味觉阈值、唾液分泌和胃电的影响，发现A型和B型受试者对光的这些生理反应存在差异。其次，我们调查了对声音的反应是否因行为模式(早晚类型)而不同，结果表明，早型和晚型受试者对声音的P300反应不同。我们还研究了合成声音对自主神经和中枢神经系统的影响，以及与听众性别有关的心理反应，并描述了这种相互作用。其次，我们调查了对低相对湿度空气的生理反应，发现老年受试者的糖精清除时间比年轻受试者增加得更多，这表明老年人比年轻受试者对这种情况更敏感。我们研究了54名受试者对低氧耐受性对体温调节反应的影响，发现低氧耐受性越高，体温调节越好。我们还测量了热暴露和冷暴露时的阈值间区，揭示了睡眠质量和对冷热的敏感性等非热因素对阈值间区的显著影响。最后，我们调查了59名受试者对心理应激的循环反应，结果表明，反应类型大致可分为两组，一组以心输出量增加为特征，另一组以总外周阻力增加为特征。我们还从这些反应的稳定性和幅度的角度揭示了亚型的可能性。

The purpose of this study was to examine the physiological polymorphism of human responses to various factors of the environment, such as lighting, sound, stress, etc. First, we examined the effects of light on cognition taste thresholds, saliva secretion, and electrogastrogram in relation to subjects' personality types (Type A and B) in 40 men, and found differences in these physiological responses to light in the Type A and Type B subjects.Second, we investigated whether the response to a sound differs depending on behavior patterns (morning and evening types), and showed that the P300 responses to the sound were different in the morning- and the evening-type subjects. We also studied the effect of a synthesized voice on autonomic and central nervous systems, and psychological responses in relation to the gender of the audience, and described the interaction.Next, we investigated the physiological responses to low-relative-humidity air, and found that the saccharin clearance time of the elderly subjects increased more than that of younger subjects, which indicated that the elderly are more sensitive to this condition than younger subjects. We studied the effects of the tolerance of hypoxia on thermoregulatory responses in 54 subjects, and found the higher hypoxic tolerance group showed better body core temperature regulation. We also measured the inter-threshold zones during heat and cold exposure, and revealed the significant effects of non-thermal factors, such as quality of sleep and sensitivity to the heat and cold, on the inter-threshold zones.Finally, we investigated the circulatory responses to mental stress in 59 subjects, and showed that the response types could be roughly classified into two groups; one characterized by increased cardiac output and the other characterized by increased total peripheral resistance. We also revealed the possibility of sub-types from the perspective of the stability and amplitude of these responses.
