Excessive relative humidity (RH) in combination with high temperature can lead to heat stress, often measured by the Wet Bulb Globe Temperature (WBGT). The Clausius-Clapeyron (CC) relationship implies that warming reduces RH if no extra moisture is added. Over coastal regions like eastern Asia, however, predominant summer monsoon favours increased transport from surrounding oceans as a result o...
Background and aims:Heat stress is a occupational major problem in Iranshahr city, which can lead to undesirable effects on health and reduce the productivity of people. This article examines this problem and its effects in different parts of Iran's Hospital in this city. Methods:This cross-sectional study was performed on 181 employees of different departments of a hospital in different perio...
The worsening urban heat island (UHI) effect poses a great challenge to the thermal comfort of people outdoors. However, there has not been summary mechanisms by which UHI affects outdoor (OTC). This paper reviews commonly used OTC evaluation indexes, data collection methods, and mitigation measures discusses relationship between OTC. review is limited peer-reviewed journal publications found i...
Introduction: Heat is one of the hazardous physical agents in the workplace. Exposure to heat and consequent thermal stress influence workers productivity in addition to adverse health effects. The aim of this study was to determine the heat stress induced productivity loss related to different tasks of farmers in Darreh Shahr city, during summer. . Material and Method: This cross-sectional stu...
Background and aim : A glance at different occupations and production processes showed that one of the important and popular occupational health problems in the workplace is improper climate conditions such as hot environments In this condition the core body temperature may increases and cause related diseases,, occupational accidents and reduce the efficiency . The purpose of this study was ...
heat stress is a significant occupational health and safety for workers in petrochemical industries. heat stress is a combination of heat load individual and environmental factors impose on workers’ bodies, which in turn, have impacts on workers’ performance, safety, and health. the present paper is carried out to determine the heat stress levels in workplace and to compare it with allowed wet ...
This study assesses heatstroke risk in the near future (2031–2050) under RCP8.5 scenario. The developed model is based on a generalized linear with number of ambulance transport due to (hereafter patients heatstroke) as explained variable and daily maximum temperature or wet bulb globe (WBGT) explanatory variable. With temperature, we performed projection case considering only climate change (C...
results the results showed that the average hr at resting, sitting (32℃ ± 0.1℃), and light workload (30℃ ± 0.1℃) were 78.52 ± 12.10, 69.74 ± 11.98, and 110.78 ± 17.91 beat/min, respectively. the average of ear canal temperature was estimated at 36.70℃ ± 0.36℃ for sitting workload and at 36.71℃ ± 0.27℃ light workload. conclusions the findings of this study illustrated that the average hr and the...
This paper intends to analyse responses of the working people to heat stress in Nepal's Tarai region. Here, the heat stress responses refer to the working environments- indoor and outdoor settings, prevailing diseases, and adaptive measures by the workers. Data were gathered from the sample households by using household survey, observation, and informal discussions. Environmental conditions in ...
