background : necessity of evaluating heat stress in the workplace, require validation of indices and selection optimal index. the present study aimed to assess the precision and validity of some heat stress indices and select the optimum index for using in heavy work activities in hot and dry climates. methods: it carried out on 184 workers from 40 brick kilns workshops in the city of qom, cent...

A visual-visual dual computer task was designed to test the effect of the thermal environment on dual task performance. The temperatures selected for testing were 20 and 35 degrees C Wet Bulb Globe Temperature (WBGT). 34 volunteers were randomly assigned to 1 of the 2 temperature conditions. Individual differences in single task performance were controlled by equating the baselines of single ta...

It is well established that high ambient heat could cause congenital abnormalities resulting in miscarriage or stillbirth among certain species of mammals. However, this has not been systematically studied in real field settings among humans, despite the potential value of such knowledge for estimating the impact of global warming on the human species. This study sought to test the hypothesis t...

BACKGROUND AND AIM Heat stress (HS) is associated with adverse health outcomes among agricultural workers, including acute kidney injury (AKI). The aim on this study was to estimate the incidence of AKI over course work shift and association HS workers in Spain, where summer temperatures are high heat waves expected be more frequent. METHODS Male were enrolled two different periods provinces: h...

Global warming causes a temperature rise and alteration of other meteorological variables that directly or indirectly affect human comfort. The wet bulb globe (WBGT) incorporates the effects multiple to provide reliable measure thermal stress. Despite large significance WBGT on public health, studies related characterization trends assessment are limited in tropical humid region like Peninsular...
