Enhancing comprehensive countermeasures against heat waves by analyzing related casualties

Abstract This study examines the trends and impacts of heatwave-related casualties in the Republic of Korea, with a focus on vulnerable populations including the elderly living alone, outdoor laborers, and migrant workers. Using integrated datasets from the Korea Disease Control and Prevention Agency and Statistics Korea, we identified key risk patterns by time, region, gender, and occupation. The findings reveal significant correlations between heatwave duration and casualty rates, highlighting structural vulnerabilities in current response systems. Drawing on international best practices, this study proposes comprehensive policy improvements including real-time early warning systems, expansion of community-based shelters, targeted protection for at-risk workers, and customized behavioral interventions. The proposed framework aims to support mid- to long-term heatwave governance under escalating climate change risks.
