Many different situations or life events can cause stress. Stress is a term used to describe a non-specific response to an unlimited area of demand. Stress is the body's response to pressure. When a person encounters stress, the body produces stress hormones that trigger a fight or response to escape and activate the immune system. Stress occurs in a variety of situations, from personal problems to the development of professional stress. However, too much stress can cause negative effects. There are three models of stress: stimulus, reaction and cognitive model of stress, and three categories of stressors: physical, psychological and social stressors. Stress can manifest in three ways: as a change in behavior, psychological reactions, and in the form of physical or physiological reactions. Categorically, stress is divided into acute stress and chronic stress. Acute stress is a type of stress that is strong and sudden, while chronic stress, on the other hand, is the type of stress that arises as a result of some permanent exposure to a total stressful situation or more stressful situations. It is important to mention PTSD (post-traumatic stress disorder) as a chronic reaction to stress. PTSD can be considered a disease or disorder. PTSD is defined as a mental disorder that results in impaired brain function and structure. The preparation is based on the data collected during the literature search, but also on the data of our research on the general population affected by the earthquake. Among the methods mentioned in the paper, the following are mentioned and used: inductive method, deductive method, synthesis method, description method, statistical method and generalization method. For the purposes of the research, three hypotheses were set, a research was conducted on 411 respondents using a questionnaire, and a statistical analysis was conducted. Furthermore, the paper presents the results of the research where it is evident that there is a statistically significant difference in the observed scales in relation to the sex of the respondents, where women are more prone to a stronger reaction to stressful events, there is a statistically significant difference in relation to the observed scales. where younger respondents showed a much stronger response to stressful events, and there is a statistically significant positive correlation between the experience of the observed stress scales.
