Nail biting is a compulsive habit developed by people especially when they are young. Also known as onychophagy, nail biting is common amongst children, and the innocent habit is considered by the psychologists as an impulse control disorder. In the American Psychiatric Association’s DSM the habit is classified under obsessive-compulsive and related disorders. The behavioral and emotional disorder usually occurs in childhood and during adolescence, and it is difficult for one to determine harmful obsession with normal behavior. People usually bite their nails when they feel nervous, stress or even insecure and often do it without even realizing it. Nail biting is, therefore, a sign of emotional or mental stress as it shows up in people who are nervous, anxious or feel down as a way of coping with those feelings (Zhang et al. 9).
