That's right, I've accused you. Do you have any idea why you do it? What are you going to do about it?
So many of us often catch ourselves tearing away at our nails. This often comes from a feeling of stress, nervousness, hunger, or boredom. In any case, it's usually related to anxiety. However, for some people, it can also be an actual mental disorder (Nails Guide) which causes people to not even know they're biting their nails, and even do it in their sleep.
Nail biting is a problem in so many ways. For ladies who are often very cautious of thier appearance, bitten nails look absolutely terrible! they're short, ridgid, torn, you often end up with hangnails, and red cuticles. It often also leads to bleeding, and infected nails. It's also very dirty (think about it, with all the things you do in a day, there's bound to be some nasy things under those nails)! Prolonged nail biting can also cause deformation of nails.
Breaking the Habit
If you're one of those people who's really interested in making their nails look extra nice, they'll probably find it fairly easy to stop out of sheer willpower. Always have a nail kit in your bag, even a small one so if your nail chips, you can easily repair it, so you won't be tempted to bite it off. If you catch yourself wanting to bite your nails (say you're really hungry, or your bored, or stressed) occupy yourself, grab a snack (only if your hungry!) or do something that will keep your mind of biting your nails.
Take care of your nails, if you can afford it get a manicure, make them look extra nice and you won't want to ruin them. If you can't afford it, do it yourself. Cut and shape your nails the way you want, and paint them. You put so much money, or hard work into them, you don't want to wreck them do you? Gel manicures happen to be one of the best things for people who have terrible nails!
If that method doesn't work for you, use a special nail polish that you can get at drug stores or department stores, it tastes really bad and it might help you stop. Also, you could try always holding something in your hands.
If you find that you're biting your nails in your sleep, you can wear a pair of gloves to bed, a pair that you can get especially for wearing to bed (usually with moisturizer on). If you're still having trouble you may have to try all these methods put together.
If you don't notice you're doing it, or you find you can not in any way stop yourself from doing it, you may have OCD, it's really rare to see that as a symptom, but not unheard of. You could talk to your doctor about it, and he/she will probably ask you about your other habits, and will diagnose you and give you a perscription for some kind of drug. They might even have a different way to get you to stop biting your nails.
