What does onychophagy refer to?

Onychophagy refers specifically to the habit of biting one's nails. It is a condition often associated with anxiety or stress, where individuals may chew on their nails to cope with feelings of tension. Recognizing onychophagy is important for nail technicians and professionals in the beauty industry because it can affect nail health and the overall appearance of the hands. In contrast, the other options describe different conditions or characteristics of nails that do not relate to nail biting. Chipped nails involve damage to the nail surface, long nails refer to the overall length of the nails, and curved nails denote the shape or growth pattern of the nails. None of these directly pertain to the act of biting.
