5.Bitten Nails
Nail biting is often a sign of anxiety or stress. For some, it’s a harmless habit; for others, it may reflect deeper emotional challenges. Known as onychophagia, it can lead to infections, dental issues, and embarrassment. Cognitive behavioral therapy, stress management, or even bitter-tasting polish can help break the cycle. If it’s affecting your life, consider speaking to a mental health professional.
