Background & Objectives : Exposure to high temperatures is common among workers in warm environments leading to some undesirable effects . The aim of this study was to examine physiological responses to heat stress to determine the optimal index for direct measurement of physiological strain in workers of hot environments . Methods: In this study, 40 workers of melting and cast...
Background: Exposure to high temperatures is common among workers in warm environments (especially in bakeries) which could cause some undesirable physiological effects. The aim of this study was to determine heat stress and its relationship with physiological parameter of sublingual temperature in workers employed in bakeries of Arak city. Methods: In this cross- sectional study, 126 workers ...
heat stress is well recognized among the hazardous physical agents that might be present during work. this study aims to compare wbgt index at acclimated and unacclimated people to permissible threshold limit value and study the differences between physiological parameters at them. twenty one healthy men were participated in the study. all of the subjects were monitored in two different weather...
conclusions the results showed that, compared to participants with normal weights, physiological and thermal perceptual responses were higher in overweight participants. therefore, overweight individuals should avoid hot/dry weather conditions to decrease the amount of heat strain. results in both groups, oral temperature, heart rate, and thermal perceptual responses increased during heat expos...
original article the objectives of this research were to study the correlations of heat strain score index (hssi) and values of wet-bulb globe temperature (wbgt) index with physiological parameters such as core body temperature, heart rate, and blood pressure of workers exposed to heat stress in a glass manufacturing plant in order to determine the reliability of hssi. this cross sectional st...
The study evaluated differences in response to exercise stress between endurance and high-intensity intermittent trained athletes in a thermoneutral environment using a physiological strain index (PSI). Thirty-two subjects participated in a running exercise under normal (23°C, 50% RH) conditions. The group included nine endurance trained athletes (middle-distance runners - MD), twelve high-inte...
introduction: the traditional view that neonates are not capable of perceiving pain has been refuted and there is now no doubt those neonates feel pain. although babies cannot express their pain as older children, but capable to show in response the pain a set of measures as observable behavioral responses. the aim of this study was to determine effect of foot reflexology on physiologic index o...
