A meta-analysis to mathematically summarize the eVect of hot and cold temperature exposure on performance was completed. The results from 515 eVect sizes calculated from 22 original studies suggest that hot and cold temperatures negatively impact performance on a wide range of cognitive-related tasks. More speci®cally, hot temperatures of 908F (32.228C) Web Bulb Globe Temperature Index or above...

Introduction: Determining methods for assessing heat stress in different work environments is one of the major challenges for researchers in this field. The purpose of this study was to validate WBGT index and heat pressure assessment (HPA) by some physiological responses in Iranian South Oil Company. Material and Methods: This descriptive-analytical study was carried out on 154 employees of K...
Background Heat is one of the most important physical harmful factors in many work environments. Due to the nature of work, bakery activity is considered as one of the high-risk occupations in terms of heat stress. Therefore, the aim of this study was evaluated of heat exposure in bakery workers using WBGT, HSI and UTCI indices. Methods This study is a descriptive-analytical cross-sectional ...
ABSTRACT: This study assessed the ways thermal environment is influenced by pre-cooling water employed in wetting porous plates present evaporative cooling systems (ECS). The experiment was performed using two physical models constructed on a distorted and reduced scale, which simulated closed agricultural facilities equipped with ECS made up of cellulose panels. In one model, were wet chilled ...
Introduction: Heat stress is considered as a serious risk factor to the health and safety of workers in most working environments, especially in outdoor works and jobs that workers are exposed to heat due to the working process. This study aimed to evaluate heat stress among workers of brick-manufacturing units in Qom city based on WBGT index as well as the relationship between WBGT and physiol...
Background and Aims: Hot and humid conditions are common in many parts of the world these conditions can influence both the health and performance of individuals. Therefore to describe the environmental conditions appropriately, the amount of reliability of heat stress indices should be measured. The aim of this study was evaluating the reliability of WBGT and P4SR by comparison to core body ...
