Is tearing fingernails a disease?

Tearing fingernails is not a disease but a common habitual behavior. This habit, commonly referred to as "onychophagia" or "onychotillomania," is often associated with factors such as tension, anxiety, stress, boredom, and typically does not significantly impact one's physical health. While tearing fingernails in itself may not pose a direct threat to physical wellbeing, it can lead to various issues. For instance, during the process, bacteria, viruses, or other pathogens may enter the body, causing skin infections. Furthermore, frequent tearing can weaken and deform fingernails, making them prone to brittleness and detracting from the overall appearance of nails and fingertips.

It is generally not recommended to tear fingernails regularly. If seeking to divert attention, engaging in deep breathing exercises, physical activities, or listening to music can be helpful alternatives. These practices can redirect focus and facilitate the cessation of this habit. In cases where necessary, psychological therapy may also be considered. It is important to monitor one's physical symptoms in daily life and seek medical attention promptly in case of any abnormalities.
