Nail biting, also called onychophagia, is a common habit, with up to 30% of the population doing it. While it may start in childhood, it can continue into adulthood and develop into a more serious condition known as dermatophagia, a type of body-focused repetitive behavior (BFRB). Those with dermatophagia compulsively bite and eat the skin on their hands and fingers, causing damage and increasing the risk of infection. If you find yourself struggling with nail-biting or dermatophagia, there are several strategies and treatments available, including cognitive-behavioral therapy (CBT) and acceptance and commitment therapy (ACT).

What You'll Learn
Nail biting as a coping mechanism
Nail biting is a common habit, with up to 30% of the population doing it. It often begins in childhood, and for many, it is a temporary phase. However, it can also persist into adulthood, and in some cases, it may be a sign of a more serious underlying issue. Chronic nail-biting, or onychophagia, can lead to negative health consequences, including damage to the nails and surrounding skin, and even potential infection due to the bacteria present in the mouth and on the hands. Therefore, it is important to address nail-biting as a coping mechanism and find healthier alternatives.
Nail biting is often triggered by specific situations or emotions. Identifying these triggers is a crucial first step in managing the habit. Common triggers include boredom, stress, anxiety, and loneliness. By recognizing these triggers, individuals can develop strategies to avoid or cope with these situations without resorting to nail-biting. For example, if stress is a trigger, incorporating stress reduction activities such as exercise, breathing exercises, or other healthy lifestyle choices can help redirect the urge to bite nails.
Additionally, replacing the nail-biting habit with alternative behaviors can be beneficial. This may include squeezing a stress ball, playing with a fidget toy, chewing gum, or simply keeping the hands busy with another activity. Keeping nails trimmed and well-maintained can also reduce the temptation to bite, as ragged edges and hangnails are common triggers for nail biters. Painting nails or covering them with tape can also serve as a visual reminder to avoid biting.
In some cases, nail biting may be a symptom of a more serious psychological or emotional problem. If individuals have repeatedly tried to quit and are unable to stop, it is recommended to consult a doctor or seek therapeutic support. Cognitive-behavioral therapy (CBT) and acceptance and commitment therapy (ACT) can help individuals address the underlying psychological aspects of their nail-biting habit. In some cases, medication may be recommended to address accompanying issues such as anxiety or depression, which can contribute to the habit.

Potential health risks
Nail biting is a common habit that often begins as a coping mechanism in response to feelings of nervousness, boredom, loneliness, or hunger. While it may not seem like a big deal, this habit can have some unexpected consequences for your health.
For one, nail biting increases your exposure to germs, as your hands come into contact with various surfaces throughout the day, picking up dirt and bacteria. By putting your fingers in your mouth, you introduce these germs, increasing your risk of getting sick with illnesses ranging from the common cold to more serious infections like salmonella.
Additionally, nail biting can cause skin damage around your nails, creating tiny fissures and leaving cuticles and skin ragged. These openings provide an easy entryway for germs to enter your body and cause infections in the skin around your nails or under the nail bed.
Nail biting can also lead to dental issues such as misaligned or chipped teeth. This is especially true if the habit is severe and uncontrollable, as constant biting can exert abnormal pressure on your teeth and jaw, leading to short-term and, in some rare cases, long-term damage.
Furthermore, if you swallow your bitten nails, there is a risk of ingesting bacteria that can cause stomach or intestinal infections. While these issues may not require immediate medical attention, they can lead to discomfort and more serious complications if left unchecked.
If you struggle with nail biting, it's important to address the underlying causes and find healthier coping mechanisms. Cognitive-behavioral therapy (CBT) and acceptance and commitment therapy (ACT) can be effective in understanding and managing the psychological aspects of this habit. Breaking the nail-biting habit can improve your health and reduce your risk of these potential issues.

Dermatophagia
Treatment for dermatophagia aims to address both the physical damage and the underlying causes. Skin treatments may include treating open wounds, scarring, and infections. There are no medications specifically approved for treating BFRBs, but antidepressants or anti-anxiety medications may be prescribed to help reduce symptoms and manage underlying conditions such as anxiety and depression. Cognitive Behavioural Therapy (CBT) is also recommended by doctors to help treat OCD and related conditions.
Additionally, habit reversal training and decoupling are popular treatment options. Habit reversal training involves learning skills to reverse the habit, while decoupling redirects the repetitive behaviour by creating an irritation to intervene before the behaviour occurs. Other holistic treatments and lifestyle changes may include stress reduction activities, replacement behaviours (such as chewing gum), and keeping nails well-trimmed to reduce the urge to bite or chew.

Treatment options
Nail biting, or onychophagia, is a common habit, with up to 30% of the population doing it. However, if you're looking to stop biting your nails, there are several treatment options you can try.
Firstly, it's important to identify your triggers. Nail biting is often a coping mechanism in response to feelings of nervousness, boredom, loneliness, or hunger. By figuring out what triggers your nail-biting, you can work on managing those triggers and developing a plan to avoid or address them.
One option is to keep your nails trimmed short and maintain them properly. This provides less nail to bite and can help reduce the temptation. You can also apply bitter-tasting nail polish to your nails, which is safe but has an awful taste that may discourage you from putting your fingers in your mouth. Keeping your nails painted or well-maintained may also make you less likely to bite them, as you wouldn't want to ruin your manicure.
Consider getting regular professional manicures. Knowing that someone will be checking on your nails soon may deter you from biting them. Choose licensed salons and manicurists who properly sterilize their tools to prevent fungal nail infections.
If you can't break the habit on your own, cognitive behavioral therapy (CBT) and acceptance and commitment therapy (ACT) can help address the psychological aspects of your nail-biting. These therapies can help you identify unhelpful behavior patterns and replace them with different, healthier behaviors.
For more serious cases, habit-reversal training can be combined with therapy. This may include finding replacement behaviors for nail-biting, such as squeezing a stress ball, playing with a fidget toy, or chewing gum.

Identifying triggers
Physical triggers, such as the presence of hangnails or uneven nail edges, are often contributing factors to nail biting. Keeping nails well-groomed and trimmed can reduce these triggers and lower the temptation to bite. Maintaining nail hygiene and covering nails with tape or gloves can also act as visual and tactile reminders to avoid nail-biting behaviour.
Emotional triggers play a significant role in nail biting. Negative emotions like stress, anxiety, boredom, loneliness, or even hunger can trigger the urge to bite nails. Identifying these emotional triggers is essential, as it enables individuals to address the underlying causes and develop healthier coping mechanisms. For example, finding alternative behaviours to replace nail biting, such as squeezing a stress ball or chewing gum, can help redirect the habit into something more positive.
It is important to note that chronic nail biting can be a sign of a more serious psychological or emotional problem. For some individuals, it may be a symptom of underlying anxiety or stress. In these cases, addressing the root cause of these emotions through therapy or medical treatment may be necessary to manage the nail-biting habit effectively. Consulting a doctor or a mental health professional can help determine if further intervention is required.
Additionally, certain medications can have nail biting as a side effect. If an individual notices a sudden onset of nail biting, reviewing their medication and discussing possible side effects with a healthcare provider may be beneficial. By identifying medication as a potential trigger, individuals can work with their doctor to adjust their treatment plan if needed.
