[Sportschosun Reporter Jang Jong-ho] During the hot summer months, it is easy to think that heatstroke or heat exhaustion only happens under strong sunlight. In reality, however, severe heat-related illness can also occur after spending long periods in hot, humid indoor environments, even without direct sun exposure.
According to Chinese media outlets including China.com, a 28-year-old man identified as A, who lives in Fuzhou, Fujian Province, recently suffered health problems after working all day in a sealed indoor space with no air conditioning and poor ventilation.
During the workday, A sweated heavily and experienced intermittent cramps in both legs. Although he did not feel well, he dismissed it as simple fatigue. When the discomfort did not go away over time, he eventually went to the hospital.
The test results were more serious than expected. Blood tests showed that his creatinine level, which indicates kidney function, was far above the normal range. Medical staff diagnosed him with acute kidney dysfunction caused by reduced blood flow to the kidneys due to dehydration in a high-temperature environment.
A is currently receiving inpatient treatment.
Medical staff explained that excessive sweating in a high-temperature environment can rapidly reduce the body’s water levels and lower the amount of blood flowing to the kidneys. They also warned that while recovery is possible in the early stages with proper hydration, prolonged dehydration or continued strenuous work can lead to permanent kidney damage.
