چکیده
Background: Thermal stress may have numerous harmful effects on human health. This study aimed at investigating thermal stress in the city of Kerman, Iran.Materials & Methods: In this descriptive-analytical study, thermal stress was assessed from 6 AM to 9 PM in 2016 using four thermal stress indices including wet-bulb globe temperature (WBGT), environmental stress index (ESI), Humidex, heat stress index (HSI), and Required Sweat Rate (SWreq). Necessary data were collected from the meteorological organization of Kerman. Pearson’s correlation coefficient and linear regression were used to examine the relationships among thermal stress indices and environmental parameters. All analyses were performed using SPSS version 22.Results: Based on the results, the highest correlation coefficients were observed between ESI and WBGT (r = 0.99), Humidex and ESI (r = 0.96), Humidex and WBGT (r = 0.97) and SWreq and HSI (r = 0.99). On the other hand, thermal stress indices had significant relationships with environmental parameters including wind speed, air temperature, and relative humidity (P < 0.05).Conclusion: All indices had strong and significant associations with one another. WBGT, HSI, and Humidex demonstrated similar thermal sensations. Furthermore, according to the obtained values of ESI, Humidex, and WBGT, people enjoy thermal comfort in all months of the year (save for January as judged by the obtained WBGT value). Thus, the climate of this city poses no threat to people’s thermal comfort.کلیدواژه ها

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
