Rising heatwave deaths in South Korea over ten years

A decade‑long health analysis highlights a worrying escalation in heat‑related mortality across South Korea. Official records indicate that deaths caused by extreme summer temperatures have increased from an average of 3.3 per year in 2012‑2015 to more than four per year after 2016.

The surge coincides with a marked increase in the number of patients treated for heat‑induced conditions. Between 2011 and 2015, the average annual count during the Ipchu period – the traditional herald of autumn – was 215. That figure leapt to 658 in the 2016‑2020 period and stayed near 638 in the latest five‑year window.

In 2024, the health burden peaked: 1,299 individuals required medical attention for heat‑related ailments, and twelve lives were lost. The Korea Meteorological Administration expects the oppressive heat to linger until the end of August, with daytime highs staying between 31°C and 35°C.

To mitigate the impact, health authorities have issued an advisory that stresses continuous hydration, staying indoors between 11 a.m. and 4 p.m., and wearing loose, cotton attire. Older adults and children are urged to take extra precautions as the sweltering season shows no sign of abating.
