It is found that the estimating indexes of heart rate variability of MRR, RMSSD and HRVI etc have different sexual sensitivity. The constant temperature airflow of the simulating natural winds can increase the active level of human's pneumogastric nerves, making human body be flabby, relaxed and comfortable. The result indicates the physiological mechanism of the effect of different winding characteristics on the human thermal comfort.
