When people chew their nails, it’s a nervous habit that causes embarrassment when others notice. But there are even more health-impacting reasons to consider. Think about not just where your hands have been, but the places your hands have touched where others (who may have disgusting hygiene) may have placed their hands.

 

Do you realize all of the germs passed between your mouth and your finger’s pores—or vice versa, when you introduce these two body parts for a fingernail chewing frenzy? All of the light switches, doors, buttons, etc, you've touched in the past week?

 

Some people may not comprehend that the actual immune system can be compromised, even HPV’s or mental illness can be inflicted by continuously chewing your fingernails and exposing your mouth to the fungus beneath.

 

Nail biting gradually increases around the teen ages, due to additional stress, puberty, etc. and creates incredible issues in your mouth, which can cause dental issues and expensive bills by compromising gums.
