Abstract. Generally the term stress refers to experiences of endangering one’s physical or psy¬chological wellbeing. Physiological stress refers to bodily adaptation processes and the maintenance of body’s balance. Selye defined stress as a function of elevated corticosteroid levels and used the term stress to refer to the effects of any agent that threatens the homeostasis of the organism. Thus, psychological stress can be defined as a discrepancy between personal capacities and environmental demands. Somatic stress symptoms are related to both physiological and psychological stress. The different types of stressors are likely to elicit divergent stress reactions. Rationale is as follows: temperament a) has a biological basis, b) is highly inherited, and c) explains what one experiences as a stress and partly determines what the health consequences are. On the basis of the results of scientific researches the strongest stress overtaking the man is the death of the partner in marriage if they lived together more than 15–20 years. Researches have cleared up the surprising, unexpected phenomenon that irreversible changes used to set in the personage if somebody occupies a leading post for a longer period. In the moment a person becomes a leader appears a distortion in its personality.
