Question
A ten-year-old boy frequently bites his nails, leading to poor nail growth. Does this behavior indicate a lack of nutrition?
Answer
Biting nails is a common phenomenon, with many people experiencing it during their childhood. However, this habit can actually pose potential hazards to a child’s healthy growth. Since children’s hands often come into contact with the outside world, they may accumulate a large number of bacteria, viruses, and other pathogens in the crevices of their nails. When children bite their nails, they may unknowingly introduce these germs into their mouths and bodies, potentially causing infections in the oral cavity or teeth, or even triggering digestive tract infections such as bacterial dysentery. Therefore, parents should correct their child’s nail-biting habit early on to protect their health.
