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.
Paint a bitter-tasting polish, such as CONTROL-IT or Thum, on your nails. The awful taste will remind you to stop every time you start to bite your nails.
Try substituting another activity, such as drawing or writing or squeezing a stress ball or Silly Putty, when you find yourself biting your nails. If you keep a record of nail-biting, you will become more aware of the times when you bite your nails and be able to stop the habit.
Wear gloves, adhesive bandages, or colored stickers whenever possible to remind you not to bite your nails.
Snap a rubber band on the inside of your wrist when you start to bite your nails so you have a negative physical response to nail-biting.
Children may bite their nails more often when they are having problems at school or with friends. Talk with your child or his or her teacher about any new stress at school. Children are more likely to stop biting their nails when they understand what may trigger it. It is also important for your child to help choose a treatment method so he or she can use the treatment successfully.
