The habit of biting nails often takes root in adolescence and can persist throughout one’s life. The longer it persists, the more challenging it becomes to break. Nail-biting is a coping mechanism, offering relief to the nervous system and a distraction from fears and worries. While the issue may not be deemed serious enough for psychotherapeutic intervention, numerous strategies exist to overcome this common but potentially harmful habit.

1. Educational Approach:
   • Allocate dedicated time to study the material concerning the pathogens that reside under the nails.
   • Gain insight into the diseases that can be contracted through nail-biting.
   • Supplement your understanding by not only reading but also watching informative videos on the subject.
2. Professional Intervention: Seek a manicure from the most skilled master in the city. This may require effort in securing an appointment, as the best masters are often in high demand. The investment in an expensive manicure, which you actively pursue, can serve as a deterrent to the habit.
3. Social Support: Enlist the help of loved ones to intervene when your finger approaches your mouth. Having someone nearby at all times can significantly reinforce the effectiveness of this method.
4. Healthy Alternatives: Keep a variety of foods on hand that can be methodically gnawed, such as raisins, bagels, dates, crackers, and fruit chips. Ensure these items are readily accessible, either by carrying them with you or placing a filled plate on your desktop.
5. Nail Maintenance Routine: Establish a routine of trimming your nail plates 2-3 times per week. Process them with a nail file to eliminate protruding parts. Promptly cut off any white stripes that appear above the skin, hastening the departure of the habit.
6. Soap Method: After washing your hands, scrape the tips of your nails with laundry soap. The lingering unpleasant taste of soap discourages repeated attempts at nail-biting.
7. Bitter-Tasting Products: Utilize a specially formulated bitter-tasting product, readily available in pharmacies and cosmetics stores, to cover your nail plates.

Consequences of Unresolved Nail-Biting: If the habit persists, it may lead to inflamed gums, fingertip sores, and dental issues, including tooth wear. Combatting helminths and infectious diseases may become necessary. Paradoxically, the habit’s continuous exposure to bacteria and viruses may have a somewhat beneficial effect on the immune system, enhancing its resilience against various diseases.

Breaking the habit of nail-biting is crucial to avoid potential health repercussions. Employing a combination of educational, preventive, and alternative strategies can contribute to successfully overcoming this common yet potentially detrimental habit.
