South Korea has recorded 267 deaths from heat-related illnesses over a 15-year period, with the majority of victims being elderly [1].
These figures highlight a critical public health vulnerability as the nation faces intensifying summer temperatures. The disproportionate impact on the elderly suggests that current cooling infrastructure and social support systems are insufficient for the most at-risk populations.
Between 2011 and 2026, 174 people aged 60 or older died from heat-related illness [1]. This group represents 65.2% of the total fatalities recorded during that timeframe [1].
Officials said several factors contribute to this trend. Many elderly citizens live alone and lack the financial means to operate air conditioning units during prolonged heat waves [2]. Exposure to high temperatures over extended periods can lead to severe medical symptoms that result in death for those with diminished physiological resilience [2].
In response to these findings, the Ministry of the Interior and Safety has modified its emergency protocols. The government raised the heat-wave disaster warning level from "caution" to "alert" [2].
Additionally, the ministry has moved to extend the operating hours of heat-wave shelters to provide more accessible cooling options for the public [2]. These shelters serve as primary refuges for those who cannot afford private cooling solutions at home.
The shift in warning levels allows for more aggressive government intervention and resource allocation during peak temperature events. By extending shelter hours, the state aims to reduce the number of elderly citizens trapped in overheating homes during the hottest parts of the day [2].

The data indicates that heat-related mortality in South Korea is not merely a meteorological issue but a socioeconomic one. The high death rate among the elderly—driven by isolation and energy poverty—shifts the responsibility of heat-wave management from simple weather alerts to a requirement for targeted social welfare and urban cooling interventions.
