Last July, a Vietnamese migrant worker in his 20s was found dead while working at an apartment construction site in Gumi, North Gyeongsang Province. His body temperature was measured at 40.2 degrees Celsius, while the city’s daytime high reached 38.3 degrees on the day he died.
That same month, another worker in his 60s lost consciousness and died while organizing shopping carts in a shopping mall parking lot in Goyang, Gyeonggi Province. In both cases, their death was linked to extreme heat.
Such grim cases could happen again this year, as forecasters warn of another unusually hot summer. For outdoor workers at construction sites and farmers in fields and paddies, who spend long hours under scorching sunlight, the risk of heat-related illness and even death is far from isolated. Heat-related illness is increasingly becoming an issue that requires actions from employers as well, such as guaranteed rest breaks, and also from the health and labor authorities.
The Korea Disease Control and Prevention Agency (KDCA) said Thursday it will begin its annual surveillance of emergency room patients with heat-related illnesses, as part of efforts to reduce health risks from extreme heat.
The program, which covers emergency rooms at medical institutions nationwide, tracks heat-related illness cases during the summer months. The surveillance will run from Friday through Sept. 30, the agency said.

Heat-related illnesses are medical conditions caused by exposure to high temperatures, such as heatstroke, heat exhaustion, heat cramps and heat syncope. According to health authorities, the estimated number of heat-related illness patients has risen sharply in recent years, as summers grow hotter and harder to endure.
The number of patients reached 4,460 last year, a tenfold increase from 443 in 2011. It was the second-highest figure on record, after 2018, when 4,526 cases were reported during one of the worst heat waves in Korea’s history. Deaths from heat-related illnesses have also increased, from around 10 per year in the 2010s to roughly 30 per year in the 2020s.
More concerningly, this summer is expected to be just as punishing as last year’s, if not worse. The Korea Meteorological Administration forecast a 60 percent chance that July’s average temperature will exceed the past average range of 24 to 25.2 degrees Celsius.
