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...

Introduction: Global warming is one of the most important environmental problems that have raised researchers’ attention. The present study aimed to analyze heat stress trends using the Wet Bulb Globe Temperature (WBGT) index in the country of Iran during the summer over a 30-year period. Materials and Methods: Daily summertime statistical data regarding mean temperature and mean relative humi...

BACKGROUND Global climate change is already increasing the average temperature and direct heat exposure in many places around the world. OBJECTIVES To assess the potential impact on occupational health and work capacity for people exposed at work to increasing heat due to climate change. DESIGN A brief review of basic thermal physiology mechanisms, occupational heat exposure guidelines and ...

Background: Climate change is one of the most complex human challenges in future. One consequences climate exposure people to heat stress, especially outdoor environments. The aim this study was model changes trend stress environments coming decades context and global warming. Methods: Wet Bulb Globe Temperature (WBGT) index, Canadian Earth System Model (CanESM2), Statistical Down Scaling (SDSM...

OBJECTIVE To examine whether non-heat acclimatized (NHA) emergency responders endure greater physiological and perceptual strain than heat acclimatized (HA) counterparts in tropical field settings. METHODS Eight HA and eight NHA men urban search and rescue personnel had physiological and perceptual responses compared during the initial 4 hours shift of a simulated disaster in tropical conditi...

BACKGROUND Presumed effects of global warming on occupational heat stress aggravate conditions in many parts of the world, in particular in developing countries. In order to assess and evaluate conditions, heat stress must be described and measured correctly. OBJECTIVE Assessment of heat stress using internationally recognized methods. DESIGN Two such methods are wet bulb globe temperature ...

BACKGROUND An important feature of climate change is increasing human heat exposure in workplaces without cooling systems in tropical and subtropical countries. Detailed gridded heat exposure maps will provide essential information for public health authorities. OBJECTIVES To develop and test methods for calculating occupational heat exposures and present results in easily interpreted maps. ...

BACKGROUND The workers who are working in the open and warm environments are at risk of health effects of climate and heat changes. It is expected that the risk is increase with global warming. This study aimed to investigate the changes of Wet Bulb Globe Temperature (WBGT) index in the past and to predict their trend of future changes in Tehran, capital of Iran. METHODS The meteorological da...

Amid the effects of global warming, Tokyo has become an increasingly hot city, especially during the summertime. To prepare for the upcoming 2020 Summer Olympics and Paralympics in Tokyo, all participants, including the athletes, staff, and spectators, will need to familiarize themselves with Tokyo's hot and humid summer conditions. This paper uses the wet-bulb globe temperature (WBGT) index, w...
