Causes of Fingernail Biting
Obsessions, compulsion, and aggressiveness are the three top causes of this disorder. Many people claim that they bite their nails as a way of relaxing or in situations like stress or distress. Any of these altered states can trigger off the unconscious nail biting habit. It is difficult to say or group the amount of people suffering from this harmful habit. In many cases, it is considered as a conscious habit of self-inflicted harm, and some specific situations may go to a negative attitude and exert an influence on the behaviour of the subject during childhood, adolescence and first years of adulthood.
