As the sweltering heat persists, heat-related illness cases have surpassed 600. According to the Korea Disease Control and Prevention Agency on the 13th, from May 15 to the 11th, 636 cases of heat-related illness were reported nationwide. There were two presumed deaths from heat-related illness. While the number is not higher than the same period last year (1,512), the tally could rise if the heat wave continues.
This year, the age group with the most heat-related illnesses was 65 and older (about 29%). The locations were outdoor worksites (21%), rice paddies and fields (19%), roadsides (16%), and sports fields (9%). Many older adults fall ill while working outdoors in hot weather. Older adults are especially vulnerable to heat because their ability to regulate body temperature declines. By region, Gyeonggi (23%), Seoul (13%), and North Gyeongsang (10%) ranked in that order.
Heat-related illness is an acute condition in which prolonged exposure to a hot environment causes dizziness, vomiting, muscle cramps, and fatigue. As the body releases sweat to dissipate heat, it loses water and salt, leading to heat-related illness. It usually resolves with rest in a cool place. However, in heatstroke, body temperature can rise above 40 degrees Celsius, leading to loss of consciousness and, in severe cases, death.
If heatstroke is suspected, call 119 and transport the patient to a medical facility quickly. While waiting for 119, move the patient to a cool place and lower body temperature with towels soaked in water. Spraying water on the body or using a fan to help dissipate heat can also help.
To prevent heat-related illness, it is best to avoid going out at midday. If engaging in outdoor activity, use a parasol and wear a wide-brimmed hat, and drink water every hour. Showering frequently and wearing loose, light-colored, lightweight clothing are also advisable.
Over the Korean Peninsula, the North Pacific high and the Tibetan high are overlapping, trapping heat. According to the Korea Meteorological Administration, the high temperature during the day was forecast at 30 to 37 C on the day and 28 to 36 C on the 14th, indicating the heat will persist for the time being.
