The wisdom of Korean medicine often aligns closely with modern medicine. Among the 'worms' discussed in Donguibogam, the culprit causing nightly anal itching is the parasite known as the pinworm. Its formal condition is called enterobiasis. While these tiny pinworms are most commonly found in young children, adults can also become infected if their immunity weakens or hygiene management becomes lax.
The lifespan of a pinworm is relatively short, lasting about two weeks to two months, but its reproductive capacity is strong. While a person sleeps at night, the female pinworm crawls out toward the perianal region, where body temperature is warm and moist, to lay eggs. At this time, the mucus secreted by the female pinworm and the eggs irritate the skin of the perianal region, causing unbearable pruritus. Because of this pruritus, one unconsciously scratches the perianal region, and while scratching, pinworm eggs adhere beneath fingernails or onto fingers. If one then touches their mouth or handles other objects with those hands, a vicious cycle can occur where it easily spreads to people nearby or leads to self-reinfection.
This nighttime itching goes beyond mere discomfort and can have serious effects on our body and mind. In particular, it disrupts sound sleep at night and can lead to chronic sleep deprivation. Sleep deprivation not only greatly disrupts daily life through impaired concentration during the day, reduced learning ability, fatigue, and increased irritability, but in the long term, it can also develop into serious health problems such as decreased immunity, hormonal imbalance, and an increased risk of cardiovascular disease. Frequent irritation and scratching of the perianal region can also cause dermatitis or secondary bacterial infection.
Furthermore, these repeated symptoms elevate psychological stress and anxiety, which can significantly lower quality of life. Thoughts such as 'Could there be something wrong with me?' and 'What if other people find out?' can follow one after another, negatively affecting mental health. Modern medicine uses a simple method called the cellophane tape test to diagnose enterobiasis, and finds that it can be treated effectively using an anthelmintic. However, prevention and daily lifestyle management remain the most important steps.
