Why does a child bite his nails?
Nail biting is a bad habit, but it has its reasons. Psychologists say that eliminating this bad habit is not about hitting the child on the hands, shaming him or yelling at him. There is even a scientific medical term for this habit - onychophagia. This is behavior that has no specific goal, motives, such behavior is irrational. A person does something only because he cannot help but do it.
This action brings him relief, but only for a short time. Then the person (child) repeats the same senseless actions again. The habit of biting nails without any purpose is called a compulsive habit.
The behavior in which a person bites his skin without any purpose is called dermatophagy.
According to research by medical professionals:
Up to a third of all children aged 7-10 have the habit of biting their nails
Boys after 10 years of age begin to bite their nails more and more often than girls (due to psychological characteristics)
More than half of teenagers from 10 to 18 years old are addicted to the habit of biting their nails and cannot quit, much like smoking. Children who bite their nails calm down for a short time, and then start biting them again. If their actions are accompanied by rude behavior of adults, slaps, screams, the neurosis of children becomes deeper, sometimes goes into a latent form, but does not disappear.
