[Asia Economy Reporter Kim Young-won] The Korea Meteorological Administration has forecast that the daily maximum apparent temperature will rise above 31℃ in most regions nationwide for the time being, prompting the Korea Disease Control and Prevention Agency to urge caution regarding heat-related illnesses caused by the heatwave.

According to the heat-related illness emergency room surveillance system operated for one month starting in May this year, 206 cases of heat-related illnesses were reported during this period, marking a 74.6% increase compared to the same period last year. If the heatwave expands nationwide, heat-related illnesses are expected to increase.

Heat-related illnesses are acute conditions caused by heat, with heatstroke and heat exhaustion being representative examples. Symptoms such as headache, dizziness, muscle cramps, fatigue, and decreased consciousness appear after prolonged exposure to hot environments, and if left untreated, can be life-threatening.

Analysis of data from the 'Heat-related Illness Emergency Room Surveillance System' from 2017 to 2021 by the Disease Control and Prevention Agency showed that a total of 10,395 heat-related illness cases were reported during this period, including an estimated 99 deaths. This averages to 2,079 cases annually. Heat-related illnesses mainly occurred outdoors, with symptoms developing during activities at outdoor workplaces (31.5%) and rice fields or farmlands (13.5%). 48.3% of cases occurred between 12 PM and 5 PM.

Prevention of Heatwaves: Follow 'Health Guidelines'

The Disease Control and Prevention Agency emphasized that health damage caused by heatwaves can be prevented simply by following health guidelines, such as drinking water frequently and resting during the hottest times of the day.

First, during heatwaves, it is important to drink fluids regularly before feeling thirsty. However, it is advisable to avoid alcohol, coffee, and carbonated drinks. Alcohol raises body temperature, and coffee or carbonated drinks containing high amounts of caffeine can cause dehydration due to their diuretic effects.

When a heatwave advisory or warning is issued, activities should be reduced during the high-risk hours from 12 PM to 5 PM. If unavoidable, wearing a wide-brimmed hat and light, loose clothing can help prevent heat-related illnesses.

If early symptoms of heat-related illness such as dizziness, headache, or nausea appear, stop activities immediately and move to a cool place to rest.

People with chronic diseases such as cardiovascular disease, diabetes, or stroke should be cautious as symptoms may worsen due to heat exposure, and it is advisable to reduce activity intensity during hot weather.

Children and elderly individuals with limited mobility should not be left alone in cars or homes. According to the 2017-2021 heat-related illness emergency room surveillance system results, 22.4% of heat-related illnesses occurred indoors. When going out is unavoidable, it is necessary to ask neighbors or relatives for protection.

When a heat-related illness occurs, immediately move the patient to a cool place. Then, wipe the body with a wet towel, water, or ice, and lower body temperature using a fan or hand fan. If symptoms do not improve, visit a medical institution. Especially if the patient is unconscious, promptly call 119 for emergency transport to a hospital, and do not force the patient to drink fluids due to the risk of choking.

Baek Kyung-ran, head of the Disease Control and Prevention Agency, urged, "Heat-related illnesses can be prevented simply by following health guidelines, so it is important to avoid prolonged outdoor activities during heatwaves, drink plenty of water, and take regular breaks."
