Today's habits and the lifestyle of people have changed, and the human body is increasingly exposed to negative environmental impacts. A cell, tissue and molecule assay that provides resistance to infection and protection from microorganisms, the immune system sometimes reacts strongly and causes allergic reactions such as asthma or fever. Allergies cause the allergens we are constantly surrounded, and we can enter them with food and drink, medicines, insect bites or inhaled them. Also, every person responds differently to a certain allergen, and an allergic reaction can cause rash, redness, itching or some other form. Allergic rhinitis, allergic skin and eye diseases, and allergic asthma are the most common allergic diseases of which an increasing number of people suffer. Allergic diseases cannot be cured but can be prevented and alleviated by various procedures and by adhering to medical instructions. In this graduate thesis, the frequency of allergic reactions in the students of the Teacher education from Faculty of Philosophy in Split, their connection with the place of living (village and city), and how many of those students with allergies withdrew was studied. An attempt was made to determine whether the genetic predisposition affects the occurrence of allergic diseases in students, as the tendency for allergies is higher in a person with a member of the allergic family. Research results show that almost double the number of students who are not allergic to those who are as well that more allergists come from the city than from the village. Also, research data show that genetics has a major influence on the occurrence of allergic reactions, and the assumption that 50% of respondents with age are cured of allergies has not proved probable and that all three hypotheses need more extensive research. Furthermore, the results of the research have shown that students have the average knowledge of allergy and that allergies have a moderate impact on the quality of their life. The results obtained in this study should encourage greater awareness of allergies, regular medical examinations, and general people awareness of their own health.
