Effect of Heat-Health Education on Heat-Protection Practices among Outdoor Workers in Nigeria

Abstract

Heat exposure is an important occupational and public health concern, particularly for workers who spend prolonged periods performing physically demanding activities outdoors. Outdoor workers may be exposed to high environmental temperatures and solar radiation, which can increase the risk of heat stress, dehydration, heat exhaustion, heat stroke, fatigue, reduced concentration, and work-related accidents. Heat-protection practices include adequate hydration, taking appropriate rest breaks, seeking shade or cooler environments, wearing suitable clothing, adjusting work activities where feasible, recognizing early symptoms of heat-related illness, and promptly seeking assistance when serious symptoms occur. Heat-health education is an important health promotion strategy for providing workers with knowledge about heat-related health risks, early warning signs, preventive measures, hydration, rest, environmental heat exposure, and appropriate responses to heat-related illness. In Nigeria, outdoor workers such as construction workers, agricultural workers, road workers, security personnel, street vendors, traffic workers, and other occupational groups may experience substantial heat exposure. However, limited awareness, high workload, long working hours, inadequate access to drinking water and shaded rest areas, socioeconomic constraints, and workplace demands may discourage consistent adoption of heat-protection practices. Effective heat-health education may improve workers' knowledge, risk perception, and ability to adopt appropriate protective behaviours. Against this background, this study investigates the effect of heat-health education on heat-protection practices among outdoor workers in Nigeria. The study is anchored on the Health Belief Model (HBM), Social Cognitive Theory (SCT), and Theory of Planned Behavior (TPB). The Health Belief Model explains preventive health behaviour through perceived susceptibility, perceived severity, perceived benefits, perceived barriers, and cues to action, providing a basis for understanding workers' decisions to adopt heat-protection practices. Social Cognitive Theory emphasizes the interaction between knowledge, self-efficacy, behavioural capabilities, social influences, and environmental conditions in shaping protective workplace behaviours. The Theory of Planned Behavior proposes that attitudes, subjective norms, and perceived behavioural control influence behavioural intentions and subsequent protective actions. Collectively, these theoretical perspectives provide a comprehensive framework for explaining how heat-health education may influence heat-protection practices among outdoor workers in Nigeria. The study adopts a quantitative quasi-experimental research design. Primary data will be collected from adult outdoor workers in selected occupational settings in Nigeria using a structured interviewer-administered questionnaire and, where feasible, a workplace observation checklist. A multistage sampling technique will be employed to select states, local government areas, occupational groups, workplaces, and eligible workers. Where feasible, selected workplaces or participants will be assigned to intervention and comparison groups. Workers in the intervention group will receive structured heat-health education covering heat-related illnesses, occupational heat exposure, signs and symptoms of heat exhaustion and heat stroke, hydration, rest breaks, shade, appropriate clothing, work-rest practices, acclimatization, recognition of heat-related danger signs, and appropriate emergency response. Heat-protection practices will be assessed using indicators such as frequency of water intake, use of shaded or cool rest areas, compliance with recommended rest breaks, appropriate clothing, adjustment of work activities where feasible, recognition and reporting of heat-related symptoms, and timely seeking of medical assistance when necessary. Descriptive statistics will be used to summarize workers' sociodemographic and occupational characteristics, exposure to heat-health education, and heat-protection practices. Inferential statistical techniques, including chi-square tests, paired-sample tests, independent-sample tests, and multiple regression analysis, will be employed to determine the effect of heat-health education on heat-protection practices. Appropriate diagnostic tests will also be conducted to assess the reliability of the research instrument, model assumptions, and the robustness of the findings. The study anticipates that heat-health education will have a significant positive effect on heat-protection practices among outdoor workers in Nigeria. Workers who receive structured heat-health education are expected to demonstrate improved knowledge of heat-related health risks and greater adoption of appropriate protective practices. Education may encourage regular hydration, appropriate rest periods, utilization of shaded areas, recognition of early heat-related symptoms, and timely reporting or management of heat-related illness. However, education alone may not guarantee consistent heat-protection practices because workers may continue to face barriers such as inadequate access to drinking water, limited shade, high workload, financial pressures, long working hours, inadequate workplace supervision, and employer productivity expectations. Consequently, heat-health education is expected to be most effective when supported by workplace heat-management policies, access to safe drinking water, shaded rest areas, appropriate work-rest schedules, acclimatization procedures, and employer commitment to occupational health and safety. This study is expected to contribute to the literature on occupational health, heat-related illness prevention, environmental health, workplace safety, health education, and public health in Nigeria by providing empirical evidence on the effect of heat-health education on heat-protection practices among outdoor workers. The findings will provide useful information for the Federal Ministry of Health and Social Welfare, Federal Ministry of Labour and Employment, state ministries of health, employers, occupational health practitioners, labour organizations, workplace safety officers, public health professionals, and policymakers regarding strategies for reducing occupational heat-related health risks. The study will also provide evidence-based recommendations for strengthening heat-health education, developing workplace heat-management programmes, improving access to drinking water and shaded rest areas, promoting appropriate work-rest schedules, strengthening occupational health monitoring, and integrating heat-related illness prevention into workplace health and safety programmes across Nigeria.
