In recent years, the term stress and its causes have attracted much interest. The term stress itself can be historically seen as a rediscovery of the concept that has developed over several centuries (Cassidy, 1999, cited in Cooper & Dewe, 2004). Furthermore, some authors have pointed out that the term evolved with the feeling of pressure, tension and difficulty associated with the 17th and 18th centuries and that what people feel today has been exactly the same across centuries (Hinckle, 1973 , cited in Cooper & Dew, 2004). Therefore, the condition has always been there. However, the study of stress has gained momentum with many different definitions, including a typical one that describes the concept as emotional and physiological responses to circumstances that are too difficult to face or resolve and for which one has no choice but to endure them ( 1). This essay will aim to discuss the causes and effects of stress, as well as the factors that trigger stressful feelings, drawing on the opinions and theories of leading psychologists and researchers in the field. For starters, stress can be caused by a number or combination of psychological and physical elements such as pollution, crowding, or noise pollution, also referred to as stressors (McEtarffer & Weseley, 2007). When it comes to crowding, although many people find it fun to have a crowd at a concert or football game, others can be psychologically affected by large numbers of people (lesson: causes). This fear of density was further demonstrated in studies by Sundstrom (1978) who found that people were less friendly and more aggressive in cities and by Pandey (1999) who examined an Indian city and concluded that people in cities have less control over their lives and lead ...... middle of paper ...... the cultural class should not be underestimated where it is possible that an authoritarian country produces nervous and anxious subjects. In a word, culture, gender, and personal traits can all combine to trigger stressful events (Cooper & Dewe, 2004). To summarize, stress is not a recent phenomenon but has always been present in humans. It is not only caused by external elements such as noise pollution or crowding (stressors), but also by some innate factors and by individuals' reactions to the events that surround them. The effects of these factors, both individually and combined, can radically change people's lives and cause various states, from impotence and anxiety to serious heart disease. Unless corrective actions are considered, such as providing ways to deal with stress and ensuring that sports and health programs are implemented, the future will not look bright.
