Know the 5 little-known Risks
Nail biting, or onychophagia, is a relatively common habit that affects people of all ages. There are many theories as to why people bite their nails, but most agree that it often stems from stress or may be an activity that’s picked up as a child.
For some people, the social stigma and embarrassment over the look of their nails causes them to become depressed, isolated, or avoid activities they would otherwise enjoy.
Beyond this, however, is there reason to worry if you regularly bite your nails?
Answer is yes. Nail biting may actually be harmful to you beyond the emotional effects.
1. Disease Causing Bacteria
Your nails are an ideal location for bacteria to thrive. Your fingernails may actually be twice as dirty as your fingers, considering they’re difficult to keep clean, making this a prime point of transfer for infectious organisms. As you bite your nails, bacteria easily transfer into your mouth and the rest of your body, where they may lead to infections.
2. Nail Infections
Nail biters are susceptible to paronychia, a skin infection that occurs around your nails. As you chew your nails, bacteria, yeast, and other microorganisms can enter through tiny tears or abrasions, leading to swelling, redness, and pus around your nail.
3. Warts Due to HPV Infections
Warts on your fingers caused by human papillomavirus, or HPV, are common among chronic nail biters. These warts can easily spread to your mouth and lips as you bite your nails.
4. Dental Problems
Nail biting can interfere with proper dental occlusion, or the manner in which your upper and lower teeth come together when you close your mouth.
Your teeth may shift out of their proper position, become misshapen, wear down prematurely, and become weakened if you bite your nails over time.
5. Impaired Quality of Life
A study published this year found that people who chronically bite their nails report significantly higher quality of life impairment than those who do not.
The level of impairment rises with time spent on nail biting, the number of involved fingernails and those who report visible nail abnormalities. Tension when trying to resist nail biting, suffering due to nail biting or nail-eating behavior also negatively influenced quality of life
