HOW TO QUIT: NAIL-BITING

Up to 30 per cent of people chew on their nails and this habit can lead to health problems such as an infection around the nail bed, says dermatologist Dr Joshua Zeichner. Biting your nails may also cause damage to your teeth and to your jaw alignment over time, he adds. Experts say the behaviour is often triggered by stress or boredom, and research suggests that it may also be genetic. To kick the habit, most people start by applying a nastytasting lacquer as a deterrent, but these strategies can also help:

IDENTIFY TRIGGERS When and where do you start gnawing? While you’re at your desk? When you meet with your boss? Pick up a pen and log when your urges occur. “It’s difficult to write or type and bite your nails simultaneously,” says Dr Meghan McMackin, an anxietyfocused psychologist. Not only will writing help prevent you from putting fingers in your mouth, but you’ll also become aware of scenarios in which you’re likely to nibble. So, you can plan ahead to implement a replacement behaviour, such as using a fidget toy or chewing gum.

TRIM NAILS Treat yourself to a luxe manicure and style your nails short – forking over money may naturally discourage you from destroying the result with your teeth. Plus, it’ll look nice and your cuticles won’t be as pickable.

COVER THEM UP Try wearing gloves, bandages or even press-on nails – anything to physically hinder you from biting.

ADDRESS THE ROOT ISSUE Sometimes nail-biting stems from boredom, which may mean you need a new challenge. Or perhaps it’s an anxious reaction to a troubling time. Consider seeing a therapist if you’re exhibiting other stress-related symptoms. And, of course, head to a dermatologist if your fingertips become swollen, tender or red.
