Nearly 200 people collapsed in a single day from heat-related illnesses during a severe heat wave in South Korea [1].
The spike in medical emergencies highlights the vulnerability of the population to extreme temperatures, particularly as the country's aging demographic faces higher risks of heatstroke and exhaustion.
On the fourth day of the heat wave, 198 people collapsed due to heat-related illnesses [1]. One person died among those who collapsed on that specific day [1]. When adding cases from the previous day, the total number of people who collapsed reached 202 [1].
Nationwide, the cumulative number of heat-related hospitalizations has now exceeded 2,400 [1]. These medical emergencies have resulted in 21 deaths [1].
Older adults have been disproportionately affected by the weather. Approximately 34% of the patients treated for heat-related illnesses were aged 65 or older [1]. Medical experts said that extreme heat, with temperatures exceeding 40°C, overwhelms the body's ability to regulate temperature [1]. This effect is more pronounced in seniors whose thermoregulatory functions decline with age [1].
To mitigate the crisis, the government has designated over 6,000 cooling centers in community centers to provide relief for the public [1]. These facilities serve as critical infrastructure to prevent further collapses as temperatures remain high.

The high percentage of elderly patients underscores a growing public health challenge in South Korea, where an aging population is increasingly susceptible to extreme climate events. The reliance on thousands of government-run cooling centers suggests that residential cooling may be insufficient for many vulnerable citizens, necessitating systemic state intervention to prevent mass casualties during peak summer temperatures.
