Psychologists have found that if one twin suffers from social anxiety disorder, the other twin is also prone to social anxiety disorder, and the similarity between identical twins is higher than that between fraternal twins. In fact, among the family members of patients with social anxiety disorder, the possibility of suffering from social anxiety disorder is three times that of the family members of patients without social anxiety disorder, which almost indicates that social anxiety disorder seems to have a "familial" tendency.

2. The imbalance of substances transmitted by the brain

Scientists have found that social anxiety disorder is closely related to the imbalance of substances transmitted by patients' brains. For example, the concentration of serotonin in the brain, which is responsible for regulating emotions, is reduced, or dopamine, another substance transmitted by the brain, is less than that of normal people, which can be done.

3. Important experience factors

For some people, social anxiety begins with an experience in the social process. For example, those who are very afraid of speaking in public sometimes recall the sudden outbreak of anxiety symptoms they experienced while speaking.

4. Family environment factors

If a father, a mother or one of them suffers from social anxiety, then by observing how parents cope with the social environment, their children are likely to be influenced by it, that is, become social anxiety patients. In addition, children who are shy, timid, prone to retreat, overprotected or controlled by their parents, and often laughed at, bullied and rejected are also more likely to suffer from this disease.
