The intensity and duration of stress changes depending on the circumstances and emotional condition of the person suffering from it (Arnold.The autonomic nervous system and hypothalamic-pituitary-adrenal (HPA) axis are two major systems that respond to stress.The axis involves the release of corticotropin releasing hormone and vasopressin from the hypothalamus which stimulates the pituitary to secrete ACTH.Acute time limited stressors, or stressors that lasted less than two hours, results in an up regulation of natural immunity and down regulation of specific immunity.

The HPA axis is subject to negative feedback regulation as well.Other psychologists, however, proposed measuring stress indirectly, through self-tests.The researchers explained that the overall effect of these movements is to boost immune readiness.When holding the strangers hand the response reduced a little but not as much as when they were holding their husbands hand.
