Systematic review and narrative synthesis of behavioral interventions to improve heat-related illness prevention in community and occupational populations

The published literature on behavioral heat-related illness prevention interventions was limited, despite frequent periods of high heat. The published evidence suggested that interventions can improve prevention knowledge and behavior and possibly reduce heat injury. Study designs need substantial improvement by including larger samples and randomized designs with comparison groups to avoid threats to internal and external validity in existing data. Policy efforts should be considered along with health education and provision of PPE to ensure populations are adequately protected.
