What are some ways to help an adult stop nail biting?

Methods for helping adults stop biting their nails include coating nails in a bitter-tasting polish, keeping nails trimmed and getting regular manicures. Other tips are using different techniques to manage stress and, for serious cases, wearing gloves or putting bandages on the fingertips.

Having something on the nails that doesn't taste good helps discourage nail biting. If nails are kept short, there isn't much left to bite, which helps break the habit. Getting manicures means spending money on having nice-looking nails, and people are less likely to mess something up that costs money to maintain. A lot of nail biting is due to stress, so techniques such as yoga and meditation help reduce stress.
