So when does it stop being a minor problem? Experts suggest paying attention when the person tries to stop but can’t, when frequent injuries occur, when there are repeated infections, or when the impulse increases in situations of intense anxiety . It is also relevant if the behavior becomes completely automatic and causes distress or shame.In some cases, onychophagia (nail biting) may be associated with anxiety disorders , chronic stress , or even obsessive-compulsive disorder . This does not mean that everyone who bites their nails has a mental disorder, but it does mean that in certain contexts, it may be part of a larger condition that requires professional evaluation.
A key point is to understand that it is not just a matter of “lack of willpower.” Reducing it to a matter of discipline often increases feelings of guilt and frustration. Often, the behavior serves to regulate difficult-to-manage emotions. Therefore, addressing the underlying causes, learning emotional regulation techniques, and developing stress management strategies may be more effective than simply trying to suppress the habit.
