Our intention has been to review the literature addressing the anxiety phenomenon from as many points of view as possible. By searching in PubMed and Web of Science and by using multiple filters, we have included, of the over 1800 results, 93 studies with the aim of covering more aspects of life anxiety exerts its influence upon. We have discussed the connection between anxiety and physiological and psychological functioning, or its connection with the areas of family, religion, social life and behavior, as well as the cultural side, childhood, pregnancy and many others.
