What Your Fingernails Reveal About Your Health You Never Knew

5.Bitten Nails

Nail biting, and sometimes biting the surrounding skin, is often a sign of anxiety and can range from a mild habit to a serious compulsion. For some, nail biting is merely a habit, but for others, it may signal deeper issues that need to be addressed. Known as onychophagia, this behavior affects people of all ages, especially children and young adults. It can lead to nail damage, infections, and even dental problems. Persistent nail biting can also affect self-esteem and social interactions. Treatment may include cognitive behavioral therapy, habit-reversal training, and stress management techniques. Some people benefit from using stress balls, fidget toys, or bitter-tasting nail polish. In severe cases, working with a mental health professional can help address the underlying causes.
