What is onychophagy commonly known as?

Onychophagy is a term used in the field of nail technology to refer specifically to the habit of biting one's nails. It is a common occurrence among individuals of varying ages and can be a response to stress, anxiety, or boredom. When someone bites their nails, the nails may become uneven, damaged, or more susceptible to infections. Recognizing onychophagy is important for nail technicians as they can provide appropriate care and suggest ways for clients to manage this habit to promote healthier nails.

The other options highlight different nail conditions or issues that are not synonymous with onychophagy. For example, nail disease encompasses a variety of infections and ailments that affect the nails, while hangnails refer specifically to small, torn pieces of skin near the nail, and nail overgrowth describes a condition where nails grow excessively long or thick. These terms describe distinct phenomena and do not capture the habitual aspect of nail biting represented by onychophagy.
