While nail-biting is a relatively common habit, eating toenails or any other nails is less common and could be considered an extreme form of nail-biting or an unhealthy habit. It is not typically considered normal behavior.
There are a few reasons why you might want to consider stopping this habit:
Health risks: Chewing and consuming nails, especially toenails, can introduce harmful bacteria into your body, potentially leading to infections or other health issues.
Dental problems: Constantly biting and chewing hard substances like nails can cause dental problems, including chipped or cracked teeth.
Social stigma: As you mentioned, you're concerned about someone noticing this behavior. It may lead to embarrassment or social discomfort if others observe it.
Psychological impact: Engaging in unusual or potentially harmful habits can sometimes be linked to underlying psychological issues that might benefit from professional attention.
If you find it difficult to stop on your own, consider seeking help from a healthcare professional or a therapist who can assist you in understanding the underlying reasons for this behavior and help you develop healthier coping strategies. Cognitive-behavioral therapy (CBT) or habit reversal training can be effective in breaking unwanted habits.
Remember, it's essential to prioritize your health and well-being, and seeking support is a positive step towards making a positive change.
