人的神经系统由亿万个神经细胞构成,其功能是识别、传递和分析来自其它细胞的信息和环境的信息。神经系统又分为感觉神经系统和运动神经系统等亚系统,感觉神经系统是人体生理各部分中对冷热最敏感的。例如,在寒冷或炎热的环境中,感觉细胞受到刺激,然后将其传递到人的大脑,从而产生了冷或热的感觉。对于感觉神经系统而言,最常见的和直接的参数是感觉神经传导速度(Sensorynerve Conduction Velocity,SCV),感觉神经传导速度随着环境温度的变化而变化;因此本发明通过大量被试者参与的感觉神经传导速度与热感觉相关性实验,得到了在中等热环境(空气温度在10℃~30℃之间)中,感觉神经传导速度与热感觉的关系如下式所示。The human nervous system consists of billions of nerve cells whose function is to recognize, transmit and analyze information from other cells and the environment. The nervous system is further divided into sub-systems such as the sensory nervous system and the motor nervous system. The sensory nervous system is the most sensitive to cold and heat among all physiological parts of the human body. For example, in a cold or hot environment, sensory cells are stimulated, which are then transmitted to the human brain, resulting in the sensation of cold or heat. For the sensory nervous system, the most common and direct parameter is sensory nerve conduction velocity (Sensorynerve Conduction Velocity, SCV). In the experiment of correlation between sensory nerve conduction velocity and thermal sensation, the relationship between sensory nerve conduction velocity and thermal sensation in a moderate thermal environment (air temperature between 10°C and 30°C) is obtained as shown in the following formula.

TSVSCV=1.1718*SCV+58.61;TSV SCV = 1.1718*SCV+58.61;
