Abstract:
The term stress "denotes the state generated by the perception of stimuli that cause emotional
excitement and, to disturb homeostasis, shoot a featured adaptation process, among other
changes, the adrenaline secretion increase producing several systemic manifestations with
physiological and psychological disorders . The term stressor in turn sets the event or stimulus
that causes or leads to stress. " (HOUASS, 2001, p 1264). The endocrinologist Hans Seyle
was the first to use the term stress as a three-phase model already in 1952; therefore Lipp
proposed quadrifásico model in 2000. The three stages of stress appointed by Selye are:
alarm, resistance and exhaustion. The alarm stage, the body perceives the stressor and tries to
fight him to eliminate it, to adapt and be able to return its homeostasis. Then-organism, or
delete the stressor and can overcome or to move to the next phase, called resistance phase
where the body eliminates the warning signs and continue fighting the stressor, and there is no
further adaptation, the body enters exhaustion phase, succumbing. (PELEGRINI, CALAIS &
SALGADO, 2012). Thus, there is some importance in the interest of deepening the behavior
of new generations of graduates against stress and its relation to other aspects not covered
here, such as sleep quality, cognitive performance in stress peaks, and even counseling to
more cases serious, and its evolution. This is essential for research and maintenance of the
new generations of health professionals, which creates a direct impact on the entire Brazilian
health.
