Nail-biting (onychophagia) is a common stress-relieving habit. You may bite your
nails in times of stress or excitement, or in times of boredom or inactivity. It can
also be a learned behavior from family members. Nail-biting is the most common
of the typical "nervous habits," which include thumb-sucking, nose-picking, hair-
twisting or -pulling, tooth-grinding, and picking at skin.
You may bite your nails without realizing you are doing it. You might be involved in another activity,
such as reading, watching television, or talking on the phone, and bite your nails without thinking
about it.
Nail-biting includes biting the cuticle and soft tissue
surrounding the nail as well as biting the nail itself..what do yu think could be the remedy to this addiction?,,,,,am a victim too.
