Relationship of heat stress with acute kidney disease and chronic kidney disease: A literature review

Abstract

Introduction: Heat stress is a physical hazard and a potential health risk which can result in various conditions ranging from discomfort, headaches, psychological disorders, heat stroke and even death in extreme cases. Factors which cause heat stress include high ambient temperature, limited air movement, strenuous physical work and direct exposure to the heat of the engine/ sun. Continuous heat stress, exacerbated by dehydration, can lead to kidney disease. This study is a literature review conducted to explore factors that influence heat stress and the relationship of heat stress with acute kidney disease and chronic kidney disease. Methods: Literature search was conducted in September 2021. Research sources were taken from several databases, namely Science Direct, ProQuest, PubMed, and Google Scholar. From the databases, 23,316 articles were from Science Direct, 140,319 articles were from ProQuest, 670 articles were from PubMed, and 288,000 articles were from Google Scholars. Out of the total database only 24 articles met the inclusion criteria. The variables in this study were heat stress, acute kidney disease, and chronic kidney disease. Results: This literature review shows that several factors which can affect heat stress are heat exposure, workload, rehydration, and rest period arrangements. Heat stress experienced by workers can cause decreased kidney function and chronic kidney disease. Heat stress conditions that are continuously experienced by workers can cause chronic kidney disease. Conclusion: Heat stress can be experienced by workers due to heat exposure, heavy workload, poor rehydration, and poor rest period arrangements. Heat stress can cause acute kidney disease and chronic kidney disease.
