Nail biting, or biting the skin around the nails, often signals anxiety and can range from a mild habit to a serious compulsion. For some, it is just a habit, but for others, it points to deeper issues that need attention. Called onychophagia, this behavior affects people of all ages, especially children and young adults. It can lead to nail damage, infections, and dental problems. Persistent nail biting can also affect self-esteem and social life. Treatment may include cognitive behavioral therapy, habit-reversal training, and stress management. Some find stress balls, fidget toys, or bitter nail polish helpful. In severe cases, a mental health professional can help address the root cause.
