South Korea Heat-Related Illnesses Triple Over Decade

South Korea has recorded a threefold increase in heat-related illnesses and deaths over the past decade, according to official data released by the Korean government. The findings, based on an analysis by a government research institute under the Ministry of the Interior and Safety, using data from the Korea Disease Control and Prevention Agency, highlight a sharp rise in patients suffering from heat-related conditions during the late summer period. The average annual number of heat-related patients rose from 215 between 2011 and 2015 to 658 between 2016 and 2020, and stood at 638 between 2021 and 2025. Deaths also increased, with 12 fatalities reported in 2024 alone.

Context and Background

The data focuses on the period from Ipchun, the traditional start of autumn in the Korean calendar, which falls on August 7, through the end of August. This timeframe captures the peak of summer heat in South Korea, when temperatures and humidity levels are at their highest. The analysis underscores a worrying trend: despite technological advancements and increased awareness, heat-related health risks have escalated significantly over the past ten years. The Korea Disease Control and Prevention Agency, which provided the underlying data, has been monitoring heat-related illnesses as part of broader public health surveillance efforts.

Key Details

According to the official report, the average annual number of heat-related patients more than tripled from the 2011–2015 period to the 2016–2020 period, and remained elevated in the subsequent five years. The mortality figures show a similar upward trajectory, rising from an annual average of 3.3 deaths between 2012 and 2015 to over 4 deaths per year between 2016 and 2025. The year 2024 was particularly severe, with 12 heat-related deaths recorded. The report also notes that heatwaves are expected to continue with limited relief until late August, with daytime high temperatures forecast to range between 31 and 35 degrees Celsius across South Korea.

Implications and Impact

The sharp increase in heat-related health issues has significant implications for public health policy in South Korea. It highlights the need for enhanced heatwave response strategies, including early warning systems, public awareness campaigns, and improved healthcare infrastructure to handle heat-related emergencies. The data also draws attention to the broader regional and global context of climate change, as many countries experience more frequent and intense heatwaves. South Korea’s experience mirrors trends observed in other parts of Asia and beyond, underscoring the importance of international cooperation on climate adaptation and mitigation.

Vision 2030 Alignment

While the report originates from South Korea, it resonates with global efforts to address climate change, a priority area under Saudi Arabia’s Vision 2030. The Kingdom has been actively pursuing environmental sustainability through initiatives such as the Saudi Green Initiative and the Middle East Green Initiative, which aim to reduce emissions, increase green cover, and combat desertification. These efforts reflect Saudi Arabia’s commitment to international climate action and public health resilience, aligning with the broader goals of Vision 2030 to create a sustainable and healthy future for all.
