The human nervous system is composed of hundreds of millions of nerve cells, and functions to recognize, transmit, and analyze information from other cells and information of the environment. The nervous system is divided into the sub-systems of the sensory nervous system and the motor nervous system, and the sensory nervous system is most sensitive to cold and heat in various parts of human physiology. For example, in cold or hot environments, sensory cells are stimulated and then transferred to the human brain, thereby producing a sensation of cold or heat. For the sensory nervous system, the most common and direct parameter is sensory nerve Conduction Velocity (SCV), which varies with changes in ambient temperature; therefore, the relationship between the sensory nerve conduction velocity and the heat sensation in the moderate-heat environment (the air temperature is between 10 and 30 ℃) is obtained through a correlation experiment of the sensory nerve conduction velocity and the heat sensation, wherein a large number of testees participate in the correlation experiment.
