Seoul, August 8: South Korea is witnessing a significant rise in heat-related illnesses as the heatwave continues into the second half of August. According to government data, the number of individuals falling ill due to heat and extreme temperatures has nearly tripled over the past decade.
The analysis conducted by a research institute under the Ministry of Interior examined data from the Korea Disease Control and Prevention Agency (KDCA). From 2011 to 2015, an average of 215 cases were reported annually from “Ipchu” until the end of August.
“Ipchu,” which marks the beginning of autumn in the traditional Korean calendar, fell on August 7 this year. This figure increased to an annual average of 658 cases from 2016 to 2020, and slightly decreased to 638 from 2021 to 2025.
During the same period, deaths related to heat-related illnesses have also risen. From 2012 to 2015, there were an average of 3.3 deaths per year, which increased to over 4 from 2016 to 2025. The situation was particularly severe in 2024, with 1,299 individuals affected by heat-related illnesses by the end of August, resulting in 12 fatalities.
The meteorological department predicts that the impact of the heatwave will persist until the end of August, indicating little relief from the heat. Maximum daytime temperatures across the country are expected to remain between 31-35 degrees Celsius. Data suggests that what is traditionally considered the onset of autumn is now becoming a serious health challenge due to extreme heat in South Korea.
In response to the rising temperatures, the health department has issued advisories. Citizens are urged to stay hydrated, avoid going outside from 11 AM to 4 PM, and wear loose, cotton clothing. The weather department has confirmed that the heat and heatwaves will continue until the end of August, with special precautions advised for the elderly and children.
