Stress and depression can lead to quiteserious consequences, however, it is very difficult to determine who is inclined to develop such states. Researchers from the university of the Australian city of Newcastle are confident that human skin can tell about the inclination with high accuracy. In particular, we are talking about the reaction of the sweat glands to the so-called “acoustic fright”, when a person is frightened by a sudden noise and cannot calm down for a long time. Researchers say that the longer a person wakes up, the more he is prone to depression and stress. They proved it in the course of the experiment.
Usually, when a person hears a loud bang,his heartbeat quickens, breathing is disturbed and sweating rises. With each repetition of sound, people are less and less frightened, and, as early studies have shown, the longer the habituation takes place, the weaker the person’s psychological stability. This, in turn, just indicates the predisposition of the individual to the development of depression.
To test this, the research team inled by Professor Eugene Nalyvayko, conducted an experiment. She first interviewed 30 young volunteers and found out what they thought about their mental health. The researchers then conducted a test, during which they were subjected to acoustic shock and their habituation rate was tested using sweat gland analysis.
The results showed that people who considerthemselves prone to stress and depression, really get used to the noise much slower than the rest. Researchers hope that this method of recognizing people prone to psychological disorders will be actively used in the military and educational institutions for taking preventive measures.
