Chronic shyness among children is not really a big deal for some people because they think this will eventually fade away especially when shy kids become adults, have already become accustomed to their surroundings and have gained friends within their social circles.
But scientific researchers show that some individuals who have chronic shyness while they were still kids still suffer from it even when they are already adults. This pushed researchers to really examine the root cause of this condition after they found out that it is more than just a natural trait or temperament.
Based on researches conducted by scientists, they found a strong evidence that chronic shyness has a link to a specific group of genes, particularly those that are linked with anxiety.
Scientists have been trying to find the specific and actual genes that cause chronic shyness, in addition to focusing on pre-existing behavioral patterns and the tendencies of individuals to suffer from chronic shyness based on the behaviors of close family members.
Scientists have found a link between one specific gene called serotonin transporter gene or STG and chronic shyness.
Based on the research, people who possess a truncated version of STG would tend to suffer from chronic shyness.
Scientists found out that individuals who have a shorter version of STG would produce less amount of serotonin, a type of neurotransmitter that is believed to have a link to positive feelings such as happiness and joy.
Scientists said a reduced amount of serotonin levels in the body had been found to have an effect on a person’s general predisposition and behavior. In some people, chronic shyness and depression occur, which have been linked to abnormal levels of serotonin in the body.
Aside from the STG, scientists also found a link between chronic shyness and another gene called the DRD4.
According to the research, people who have a truncated version of the DRD4 gene may find themselves inactive and have lower inclination to try new adventures and things.
They also don’t want to expose themselves to unfamiliar people or situations.
When people who have a shorter version of the DRD4 gene are exposed to unfamiliar people or situations, they would tend to suffer from stress, as a psychological response.
Their minds perceive the situation as a threat or danger and the body reacts to it by producing the symptoms of stress.
Though scientists have concluded that chronic shyness may have a link to a person’s genes, it is not solely the cause. There are still other predisposing factors why people suffer from chronic shyness. It is only the shy people who can determine what really causes their shyness. And it is only them who can do something to completely treat the condition, with the help of their parents, friends and sometimes, professionals, in severe cases.
