Environmental StressorsWhen people are unhappy with their circumstances, they may adapt by adapting or changing their living environment to make it more pleasant. However, this characteristic of flexibility accommodates daily challenges involving external forces, such as crime, war, natural disasters, or technological developments, in addition to internal forces, such as the pursuit of more material goods. When these forces combine to threaten adaptability in humans, it is commonly referred to as stress (Veitch & Arkkelin, 1995). To deal with stress you must first understand what it entails. By understanding the concept of stress as well as its physiology and psychology, it is possible to identify atmospheric environmental stressors and define strategies to manage them. Considering the effect of stress on human functioning can be an effective way to understand the relationship between behavior and stress. environment; can help begin to identify environmental qualities that interfere with human functioning (Evans & Cohen, 1987). Most researchers agree that the concept of stress is “a state that occurs when people are faced with environmental demands that require them to change in some way” (Vetch & Arkkelin, 1995, p. 118). However, it is unclear whether such a request is stress or whether stress is a person's response to the request. Therefore, there are different theoretical perspectives regarding the concept of stress. Below are just two of the theoretical perspectives (Veitch & Arkkelin, 1995). Some theorists believe in a response-based explanation. According to them, stress is a change in the amount or strength of a particular human reaction such as blood pressure, heart rate, anxiety or loss of control.
