Abstract
In Australia’s construction industry, workers are increasingly facing the challenges of rising temperatures due to climate change. Prolonged exposure to high heat can lead to serious health issues such as heat exhaustion, dehydration, and even heat stroke. Beyond physical ailments, excessive heat can impair cognitive functions, increasing the risk of workplace accidents. The demanding nature of construction work, often performed outdoors and requiring protective gear, exacerbates these risks.
This research aims to investigate the health impacts of heat stress on Australian construction workers. By analysing existing policies, workplace practices, and firsthand accounts from workers, the study seeks to identify gaps in current protective measures. The goal is to develop recommendations for more effective heat management strategies, ensuring the safety and well-being of those in the construction sector.
As global temperatures continue to rise, it’s imperative to address the occupational hazards posed by heat stress. Protecting construction workers not only safeguards their health but also ensures the sustainability and productivity of the industry.
Introduction
Australia’s construction industry, a cornerstone of the nation’s economy, is increasingly grappling with the challenges posed by rising temperatures. Construction workers, often engaged in physically demanding tasks under direct sunlight, are particularly susceptible to heat stress. This condition can lead to a spectrum of health issues, ranging from dehydration and heat exhaustion to more severe outcomes like heatstroke.
The significance of this issue is underscored by empirical evidence linking outdoor work in high temperatures to increased health risks. For instance, a study conducted in Adelaide found that the risk of occupational heat illness during heatwave periods was approximately seven times higher than during non-heatwave periods over the years 2001–2010. Furthermore, research indicates that with each one-degree increase in maximum temperature above 35.5°C, the risk of occupational heat illnesses rises by 12.7%. These statistics highlight the direct correlation between ambient temperature and the health of outdoor workers.
Despite existing safety standards and regulatory measures aimed at protecting workers from heat-related hazards, incidents of heat stress continue to be reported. This persistence suggests that current strategies may be insufficient or inadequately implemented. Moreover, the dynamic nature of construction work, which often involves varying locations and schedules, adds complexity to the effective management of heat exposure.
Addressing heat stress in the construction sector is not only a matter of individual health and safety but also of broader public health and economic concern. As climate change progresses, the frequency and intensity of heatwaves are expected to increase, potentially exacerbating the risks faced by outdoor workers. Therefore, it is imperative to re-evaluate and enhance current protective measures, ensuring they are robust, adaptable, and effectively enforced to safeguard the well-being of construction workers across Australia.
Systematic Literature Review
The relationship between heat stress and the health of construction workers in Australia has garnered increasing attention, especially in the context of climate change. While existing literature acknowledges the risks, several gaps remain that this research aims to address.
Fatima et al. (2023) highlight that, despite established safety standards, there has been a reported increase in heat-related incidents among construction workers. This suggests that current measures may be insufficient or inadequately implemented. Similarly, Han et al. (2024) conducted a meta-analysis revealing that 60% of construction workers exposed to elevated temperatures experienced significant productivity loss, underscoring the tangible impact of heat stress on worker efficiency.BioMed Central
However, a comprehensive understanding of all existing risk factors and their corresponding control strategies remains incomplete. A recent systematic review by [Author(s)] (2024) emphasizes the need for a more holistic approach to identify gaps in current control strategies and develop effective heat stress management frameworks. This includes evaluating the effectiveness of commonly studied control methods such as cooling vests and work–rest schedules.MDPI+1rrpress.utsa.edu+1
Moreover, there is a lack of empirical evidence linking heat exposure directly to specific health outcomes among construction workers. While studies have documented the general effects of heat stress, detailed investigations into the physiological and psychological impacts on this specific workforce are limited. This gap hinders the development of targeted interventions and policies.
In conclusion, while the existing literature provides a foundation for understanding the risks of heat stress among construction workers in Australia, significant gaps persist. This research seeks to fill these voids by conducting a comprehensive analysis of the health impacts of heat stress, evaluating the effectiveness of current control measures, and proposing evidence-based recommendations for policy and practice.
Research Objectives
The primary aim of this study is to investigate the impacts of heat stress on the health of construction workers in Australia, with a focus on identifying gaps in current occupational health and safety (OHS) policies and practices. The objectives are as follows:
By addressing these objectives, the study aims to contribute to the development of more effective strategies for managing heat stress in the construction industry, thereby improving worker health outcomes and productivity.

Ethical Considerations
Conducting a systematic literature review (SLR) on the impacts of heat stress on the health of construction workers in Australia necessitates careful attention to ethical issues, particularly concerning data integrity, bias, and transparency.
Data Integrity and Bias
Given that this SLR relies on secondary data from existing studies, ensuring the accuracy and reliability of the included research is paramount. To mitigate potential biases, studies will be selected based on rigorous inclusion criteria, emphasizing methodological quality and relevance to the Australian context. The Joanna Briggs Institute (JBI) critical appraisal checklist will be employed to assess the quality of each study, ensuring that only robust and credible research informs the review’s findings.
