A heatwave warning has been issued across the country. Currently, the North Pacific high pressure system is blowing hot water vapor into the lower atmosphere of the Korean Peninsula, while the Tibetan high pressure system is drawing hot, dry air into the upper atmosphere, resulting in overlapping hot air layers.
The heatwaves are expected to continue until at least the 14th. As the heatwaves continue, many people have suffered from heatstroke. The Korea Centers for Disease Control and Prevention announced the results of their heatstroke emergency room monitoring system.
According to the report, three people have died each day over the past three days from heatstroke. A person collapsed in a field in Changwon City, Gyeongsangnam-do, at around 4:54 p.m. on the previous day (3rd),
When fire officials arrived at the scene and checked on the condition of a woman in her 50s, she was found to have a body temperature of 41 degrees and was unconscious. The woman was transported to a nearby hospital where she received first aid.
At around 2:05 p.m. on the same day, fire authorities received a report of a person lying on a wooden board in Changnyeong County, South Gyeongsang Province.
A woman in her twenties was found and taken to a nearby hospital, but was pronounced dead. She was presumed to have suffered acute cardiac arrest due to heatstroke. At the baseball stadium, where the game continued despite a heat wave warning, spectators complained of heatstroke.
An ambulance was called in. A Doosan Bears official said, "Five spectators suffered from heatstroke during a home game against the Kiwoom Heroes at Jamsil Baseball Stadium in Seoul on the 3rd.
Four of them were taken to a nearby hospital by ambulance." In addition, professional baseball games scheduled to be held at Seoul Jamsil Baseball Stadium and Ulsan Baseball Stadium that day were canceled due to the scorching heat.

Regulation 27 explicitly states that a match may be cancelled if the disruption is expected to last for more than two days.
