Physiological polymorphisms in response to environmental factors of light and ambient temperature and its human adaptability

1.通过阐明荧光光谱和LED光谱对乳头肌反应的个体差异的影响，我们获得了光源对夜间褪黑素释放影响的适当光谱分布的重要数据。墙体在同一光源下的光反射显示，吸收短波长成分的木质材料引起的褪黑素抑制率低于其他材料。光诱导的褪黑素抑制率衡量生物节律的光敏性，人类的光敏机制在冬季对日光不足的反应被增强，而高纬度地区的典型光/淡虹膜适应于增强昼夜节律系统的光敏性。因此，这些机制的意义在于预防与季节性日光暴露不足相关的抑郁症和相关健康问题。生命因子…的作用进一步阐明了S弱化基础代谢率对耐冷性的影响，即与环境适应相关的生理多态因素。根据与生活习惯调查的相关性，制定了提高耐寒能力的生活活动指南。参照个体对热或冷敏感视角的主观感知，同一房间条件下的皮肤和核心温度的量化结果以及主观数据表明，当考虑到性别、年龄和季节的差异时，主观评估可能不一定从生理反应的角度反映环境适应。立位应激引起的心率加快伴随着个体变异的增大。在热中性环境下，个体差异比季节差异更是影响立位调整的主要因素。此外，个体内部的日常变化似乎是炎热环境下立位耐力下降的主要原因。较少

1. By clarifying the effects of fluorescent and LED light spectra in each on the individual difference of papillary response, we obtained the important data on the appropriate spectral distribution of the light sources with regard to their effects on nocturnal melatonin release.2. Light reflection of the wall under the same light source revealed that wooden materials that absorbed the component of short-wave length elicited a less melatonin suppression rate than other materials.3. The light-induced melatonin suppression rate measures light sensitivity of biorhythm, the light-sensitive mechanism in humans is enhanced in response to insufficient daylight illumination in winter while typical light/pale irises at high-latitude regions accommodate to enhance light-sensitivity of the circadian system. Therefore, the significance of these mechanisms is to prevent depression and relevant health problems associated with insufficient seasonal daylight exposure.4. The effects of the living factor … More s attenuating the basal metabolic rate on cold tolerance were clarified; i.e. the factors and their relevant physiological polymorphism with environmental adaptation. Based on correlations with the survey of living-habits, guidelines on living activity to improve cold tolerance were formulated.5. With reference to the subjective perception of hot- or cold-sensitive perspectives of one self, quantitative results of skin and core temperatures and subjective data under the same room conditions revealed that subjective assessments might not necessary reflect environmental adaptation from the aspect of physiological response when differences in gender, age and season were taken into consideration.6. Increases in the heart rate induced by orthostatic stress are accompanied by augmentations in the individual variation. More than seasonal difference, individual difference is the major factor responsible for the orthostatic adjustments under thermally neutral environment. Furthermore, the day to day variation within an individual appeared to be the major contributing factor with decreases in the orthostatic tolerance under a hot environment. Less
