Why do people bite their nails, even though it’s often discouraged?

Nail biting, or onychophagia, is a common habit that can be linked to stress, anxiety, boredom, or even perfectionism. For some, it’s a way to cope with uncomfortable feelings or to keep themselves occupied. While it might offer momentary relief, chronic nail biting can lead to issues like damaged nails and skin, infections, or even dental problems. Breaking the habit often requires finding healthier ways to manage stress or anxiety.
