A recent research conducted by the experts from the University of Montreal shows that biting nails is an impulsive behavior, typical for perfectionists, who are often stressed, anxious or bored.

“We believe that individuals with these repetitive behaviors may be perfectionistic, meaning that they are unable to relax and to perform task at a ‘normal’ pace,”says Dr Kieron O’Connor, professor of psychiatry at the University of Montreal and the lead author of the study- “They are therefore prone to frustration, impatience, and dissatisfaction when they do not reach their goals. They also experience greater levels of boredom.”

Forty-eight people participated in the study, half of whom were prone to this type of behavior, while the other half had the role of a control group. The participants answered questions about boredom, anger, guilt and anxiety they experience. Then they were put in situations created with the aim of provoking certain feelings like-stress, relaxation, frustration and boredom. In order to check their reaction to boredom, they were left for six minutes alone in a room with no phone, computer or a magazine…All this showed that people who often bite their nails or fidget a lot usually do that because they are stressed, bored or anxious.
