Galina Idova, professor of the Department of Physiology at Novosibirsk State University and principal investigator of the Research Institute of Neuroscience and Medicine, told socialbites.ca that mild and short-term stress causes stimulation of immune parameters.
“Stress that is not very strong and short-term causes stimulation of immune parameters. Chronic stress, on the contrary, reduces them. Any type of stress negatively affects thymus function, and this is the central immune organ from which almost all T cells are created. The immune system naturally suffers from this,” Idova said.
Like animals, humans’ attitudes to stress greatly influence the body’s stress response. Stress causes a decrease in the immune response in mice with aggressive behavior, an increase with depressive behavior, and the effect of stress on the immune response is not revealed with submissive behavior.
But it is interesting that optimists feel stress more acutely, which also affects the immune system.
“It is known that people who believe that everything will be fine and think positively perceive stress as a terrible thing. Therefore, it greatly reduces their immunity. Stress does not affect pessimists in this way: They thought everything would be bad, and it really was,” the expert noted.
