So, you can get yeast infection from biting your nails

If your go-to nervous habit is chewing on your nails, then listen up: because this is one problem that has ramifications beyond how your hands look.

In fact, nail- biting can actually lead to a few other health issues, says Dr Robin Evans, a dermatologist at Southern Connecticut Dermatology and a clinical instructor at the Albert Einstein College of Medicine in New York City.

The main issue? Nail-biting can remove so much of the nail that it increases your risk of developing cuticle and inflammatory infections like paronychia (a bacterial or fungal infection).

If you bite your nails so short that you draw blood (yes, that happens), you can open your skin up to other viruses like warts and even yeast infections. And if you bite your nails for a long enough time, you can eventually affect the nail matrix (a.k.a., the root of the nail), which can cause nails to look misshapen and, frankly, gnarly, says Dr Susan Bard, a dermatologist at Vive Dermatology Surgery and Aesthetics in New York City.

All of that, of course, is in addition to nail-biting being super unsanitary. ‘Not only can you transfer infection from your dirty hands into your mouth but you can also transfer infections from your mouth to your hands,’ says Dr. Bard.

Basically, nail-biting isn’t a great idea. But what if you just can’t stop? There’s always hope. Try these nail-saving techniques.

1. Buy some nail polish that makes you cringe

No, I don’t mean a shade of puke-green. For mindless munchers, try something that has a foul taste – as that can be enough to break the habit, says Dr Chris G. Adigun a dermatologist and a nail specialist in Chapel Hill, North Carolina.

Some clear polishes have a bitter (but ultimately harmless) taste, and they’ll certainly make you aware of your nail-biting if you tend to do it without realising it.

2. Get a manicure

No doubt, if your nails are done up—and you just doled out some dough to have them done—you might be less likely to want to ruin the work.

3. Know your triggers—and how to avoid them

If you’re a nervous nail biter, identify when and where your tension crops up, says Kieron O’Connor, PhD, director of the obsessive-compulsive disorder (OCD) spectrum study centre at the University of Montreal.

For example, maybe you notice that when you’re on a tight deadline, you feel the need to do something with your hands—and then your nails turn to stubs. Knowing that, and coming up with what O’Connor calls a ‘competing action’ (like putting your hands on your knees instead of in your mouth when you feel anxious) can help you change your response to stress. Other relaxation strategies like deep breathing can help, too.

‘Nail biters tend to be perfectionists,’ says O’Connor. But pushing yourself too hard can lead you to feel like you’re never doing enough (even if you are). ‘These type of situations trigger nail biting,’ he notes.

Sound familiar? Take stock of your expectations. Maybe you’re setting goals for yourself that are too unrealistic to ever meet, or maybe you’re not giving yourself enough credit. Then think: ‘What’s a challenging but attainable goal?’ ‘How am I performing compared to other people in my position?’ The aim here is to prevent the nail biting in the first place by addressing the thoughts and emotions that cause it, says O’Connor.

5. Try taking a special supplement.

If bad-tasting polish isn’t your jam, N-acetyl cysteine (NAC), an over-the-counter supplement, can be helpful in kicking the nail biting habit, Dr. Bard says. She points to a 2013 study in the journal Anti-Inflammatory & Anti-Allergy Agents in Medicinal Chemistry that found NAC can decrease nail-biting behaviour in children and adolescents—likely because NAC plays a role in regulating the body’s reward and reinforcement system.

6. Swap it out for a better habit

One way to work on breaking this habit is to be consciously aware of when you’re doing it, rather than zoning out and doing it absentmindedly. Then, switch to another behaviour, such as sitting on your hands, chewing gum, or sucking on lozenges or mints, says Dr. Evans.

Something important to keep in mind, though: It takes about three weeks to break a habit and form a new one, says Dr. Bard, so it’s important not to give up too soon.

7. Talk to someone about it (yes, really)

Sometimes, you just can’t stop. If you have medical complications from biting—or if your habit is linked to psychological issues like anxiety disorders (or you think it could be)—a mental health professional can provide the support you need, says Dr. Adigun. So if you think your biting is obstructing day-to-day life, make an appointment.

There are many professionals who specialise in conditions like OCD and anxiety who can help quell your worries—and hopefully help you cut the habit for good.
