After rainfall, high humidity combined with a heatwave can elevate the perceived temperature, increasing the risk of heat-related illnesses. Therefore, exercising extra caution is crucial.
According to the Ministry of the Interior and Safety, 8,677 cases of heat-related illnesses occurred from 2019 to 2023, resulting in 81 deaths. The ministry highlighted an upward trend since 2019 and urged the public to take proactive measures to safeguard their health.
2,818 reported cases of heat-related illness were reported in 2023 alone, 1.8 times higher than in 2022, with deaths increasing approximately 3.6 times to 32. Analysis of the cumulative data shows a significant increase in heat-related illnesses after the monsoon season ended on July 26, emphasizing the need for heightened health vigilance post-rainy season this year.
Since the start of the early summer heatwave, 580 reported cases of heat-related illnesses have occurred, an increase of 88 cases compared to the same period in 2023.
The majority of heat-related illnesses, 913 cases or 32% of the overall 2,818, occurred in outdoor workplaces. This was followed by rice paddies and fields, 395 cases or 14%, and roadsides, 286 cases or 10%, highlighting the frequent occurrence of these illnesses in outdoor settings.
An analysis of the age distribution of heat-related illnesses by location shows that the highest number of cases occurred among individuals in their 50s, with 284 cases reported in outdoor workplaces. This was followed by those in their 40s with 175 cases and those in their 60s with 166 cases. In rice paddies and fields, a significant 76% of the cases, totaling 301 out of 395, affected individuals aged 60 and older, stressing the need to prioritize this age group in preventive measures.
During a heat advisory in workplaces, employees should take breaks of 10 to 15 minutes every hour and adjust their schedules to avoid outdoor tasks during peak heat hours.
It is advisable to minimize outdoor activities during peak sun hours. If outdoors, individuals should rest in shaded areas or seek cool environments.
On hot days, it’s crucial to drink water regularly, even if you don’t feel thirsty, and avoid consuming caffeinated and carbonated beverages excessively.
When using air conditioning in places with infants or elderly individuals, maintain a temperature difference of about 5℃ (9℉) between indoors and outdoors, ensure regular ventilation, and avoid leaving children unattended in vehicles during extreme heat, requiring heightened vigilance from caregivers.
Lee Han Gyeong, head of the Disaster Safety Management Headquarters, emphasized, “During heatwaves, it is crucial to avoid outdoor activities and prioritize health by staying hydrated and taking breaks as temperatures rise.” He further cautioned, “Especially during intense sunlight hours, outdoor work and agricultural activities pose significant risks, so minimizing exposure and following national guidelines are essential for a healthy summer.”
