Why do people bite their nails when they’re anxious?

In: Biology

Answer 1

I do it myself subconsciously when i am really stressed out. Its kind of like an impulse of when you are lazy and depressed you tend to eat junk food or do unhealthy habits. I feel like it is a comfort thing that is similar to babies with a pacifier or young kids sucking thier thumbs.
