The article deals with the effect of five-factor model (Big Five) personality traits on the perception and evaluation of load and own health. Its main objective is to determine how personality traits according to five-factor model of Big Five affect self-perception of health and stress levels associated with an occupation and life in general. On research participate 672 respondents (311 men and 361 women) working in different professions. The methods were NEO FFI inventory and questionnaire of work and non-work load designed by the author. Values of measured personality variables were correlated with the perception of own health and perceived stress. Further the personality traits of two contrasting groups in terms of assessing their own load and health were compared. The results suggest that the observed personality traits are reflected in the perception of stress in a manner substantially corresponding to their definition.
