Nail Biting: A Small Habit with Big Risks

The Indonesian Ministry of Health explains that the habit of nail biting is one of the main causes of paronychia, an infection of the skin around the nail. When nails are bitten, the surrounding skin becomes damaged and open, allowing bacteria such as Staphylococcus aureus to easily enter and cause inflammation. Symptoms can include redness, swelling, pain, and the appearance of pus on the skin around the nail. If not treated promptly, this infection can potentially spread deeper, attacking tendons, bones, or the bloodstream.

Besides posing a risk to the skin and nail tissue, this habit also opens a pathway for germs to enter the body through the mouth. Hands that frequently touch various surfaces carry a lot of bacteria and dirt, which are then swallowed when the nails are bitten. Unsurprisingly, people who frequently bite their nails are more susceptible to digestive disorders and mild respiratory infections such as colds and sore throats.

The good news is that this habit can be controlled. The Ministry of Health recommends keeping nails short and neat so they are less tempting to bite, and immediately diverting attention to another activity when the urge to bite arises, such as squeezing a stress ball or chewing gum. Maintaining regular hand hygiene also helps reduce the risk of infection even if the habit has not been completely eliminated.
