Stress ConsequencesStressors encountered by humans may comprise major insults ranging from the loss of loved ones, unexpected calamities (hurricane, tornado, flood, war, accident), and financial distress, or they may involve a series of day-to-day annoying experiences. Both the severe and less intrusive stressors may influence physiological and behavioral processes, and both have been implicated in the provocation or exacerbation of a large number of illnesses, including the classical psychosomatic disorders and depressive illness, cardiovascular disease, as well as those that involve immune dysfunction.
