Nowadays, stress can affect a person from various directions and areas, and as a rule, a person encounters them on an essentially daily basis. The aim of this study is to find out how a student's personality type affects the level of stress experienced during university studies. The investigation itself focuses only on full-time bachelor's students of the second year of a particular university. It is mainly a comparison of stressors and their intensity between students of bachelor's and master's programs. The content of this study is to recognize what specifically causes stress in relation to their studies in the university students addressed. In summary, the main outputs of the work can be summarized by pointing out the differences between introverts and extroverts in experiencing stress among the students addressed. However, for half of the respondents, the experienced stress gradually decreases during their studies, which indicates the adaptation of the students to the given conditions and environment. Nevertheless, 22% of respondents resorted to the use of stimulants due to the stress of studying.
