Impact of Heat Stress and Its Impression on Cardiac Jeopardy Among Construction Laborers: A Consequence for a Climate Change Imminent

Abstract

AbstractExtreme workplace heat exposures create eminent threats like heat stroke, and it confines the laborers’ aptitude to withstand physical activity. Cumulative heat waves predominantly in urban areas where construction work is more extensive. There is confined proof displayed on how these impacts reduce work efficiency; however, the quantitative relationship between heat stress and work efficiency is a crucial foundation for climate change impression evaluations. 124 male laborers from different construction sites of West Bengal were indiscriminately taken for this study. This investigation means to outline the impacts of heat stress and its impact on cardiac jeopardy among the construction laborers. This study consisted of HOTHAPS questionnaire study, environmental measurements of heat stress exposure in workplace surroundings, and different cardiac load assessment parameters like working and partial recovery heart rate, maximum heart rate, average working heart rate, maximum working heart rate, sum of recovery heart rate, percentage of recovery, percentage of recovery cardiac cost and net cardiac cost, etc., which were studied by using heart rate monitor. The study findings suggest that there are voluminous heat-allied symptoms in summer months. Most laborers reported exhaustion and pain during work on hot days. Heart rate recovered quickly at low heat, but more slowly at high heat, demonstrating cardiac jeopardy. From the study, it could be resolved that the construction-related jobs are exceptionally strenuous especially in hot environmental circumstances. It used to require extreme muscular force, which can upturn the cardiac burden.KeywordsConstruction laborersClimate changeHeat stressCardiac jeopardy
