The urban thermal environment has been deteriorating these days due to global climate change and the occurrence of heat-related illness have emerged as the major social problems. This study is aimed to analyze the Heart rate variability (HRV) of human body based on the subject experiments in different urban thermal environments during summer. We measured the environmental conditions by PMV meter and thermal imaging camera. During the subject experiments, the measured R-R interval data by heart rate sensor (Polar H10) in two-minute interval were used for the analysis of HRV. LF/HF ratio was used for the HRV evaluation. Two subjects were tested in different environment conditions during summer. We analyzed the correlation between the urban thermal environment and HRV of human body. Statistically F-test and T-test were performed at 95% of the confidence intervals to see if the comparison of the data is significant. Given the differences between indoor and outdoor thermal environments, there was a significant difference in the HRV values . The variable that has a significant impact on the outdoor environment seems to be the sensitivity of the subject individual to environmental changes. The results showed that the direct solar incidence to persons or variation in the pavement material was not significant within a limited range of outdoor environmental conditions (2?PMV?3). |
