"I Don’t Even Remember Washing Up or Going to Sleep"...Nam You-joung Reveals the Aftereffects of Grueling Practice [Health Talk]

[Financial News] Singer Nam You-joung has revealed how she prepared to take the stage in Sokcho, Gangwon Province, on the 22nd. She said that she experienced extreme fatigue and dizziness after practicing choreography for long hours while also managing her figure. Caution is needed because a sudden increase in exercise during the summer, combined with dietary restrictions, can cause exhaustion, dizziness, and reduced concentration.

On August 30, a behind-the-scenes video of Nam You-joung’s “2026 WATERBOMB SOKCHO” was posted on the YouTube channel “Youlalla.” In the video, Nam You-joung discussed her choreography practice and figure-management routine before the performance.

Speaking about how she managed her weight, Nam You-joung said, "People used to say that you should lose weight by starving yourself, but aerobic exercise is the best way to lose weight." She continued, "I danced for nine hours last week. I usually dance for five hours at a time," revealing that she had been doing intensive practice four times a week. She added, "K-pop dance is the best for dieting."
A few days later, she said that she was not feeling well. Nam You-joung said, "I just slept in the car the whole time. After it was over, I came home and don’t even remember how I washed up or fell asleep." During practice, she also explained, "Even with my eyes closed, I felt dizzy." Nam You-joung got back on her feet and continued practicing. She said, "Let’s do a little more," and continued preparing for the stage.


Dancing is an activity that requires both aerobic exercise and muscle use. Repeatedly moving the entire body to music and continuously changing direction can quickly raise the heart rate and body temperature. If someone practices for long periods while excessively restricting food intake to lose weight, dizziness, exhaustion, and reduced concentration may occur.

The Korea Disease Control and Prevention Agency (KDCA) describes heat-related illnesses as acute conditions caused by heat. Prolonged exposure to high temperatures can cause headaches, dizziness, muscle cramps, fatigue, and impaired consciousness. When preparing for an outdoor stage or summer festival, people should check the practice venue’s temperature and humidity, fluid intake, and rest intervals.

If fatigue after exercise does not improve after a day or two of rest, or if dizziness keeps recurring, the exercise intensity may have been too high for the person’s physical condition. Mayo Clinic describes reduced exercise performance, excessive fatigue, prolonged pain, and changes in sleep as signs of overtraining. If chest pain, severe shortness of breath, or dizziness occurs during exercise, the intensity should be reduced and the person’s condition should be assessed.


Even when increasing exercise to lose weight, sharply reducing food intake can lower practice efficiency. Insufficient carbohydrate and protein intake can cause energy to run out quickly during exercise and delay muscle recovery. Fluid and electrolyte replacement is also necessary in environments where people sweat heavily.

In particular, Nam You-joung’s comments that she "didn’t even remember how she washed up or fell asleep" and felt "dizzy even with her eyes closed" should not necessarily be dismissed as simple fatigue. If dizziness recurs or is accompanied by vomiting, a severe headache, chest pain, fainting, or impaired consciousness, the cause should be evaluated by a medical professional.
