Such conceptualizations are known as stimulus-based definitions because they characterize stress as a stimulus that causes certain reactions. Some have conceptualized stress as a demanding or threatening event or situation (e.g., a high-stress job, overcrowding, and long commutes to work). Researchers have had a difficult time agreeing on an acceptable definition of stress. Despite the widespread use of the term, stress is a fairly vague concept that is difficult to define with precision. Today, we often use the term loosely in describing a variety of unpleasant feeling states for example, we often say we are stressed out when we feel frustrated, angry, conflicted, overwhelmed, or fatigued. The term stress as it relates to the human condition first emerged in scientific literature in the 1930s, but it did not enter the popular vernacular until the 1970s (Lyon, 2012). Understand the physiological basis of stress and describe the general adaptation syndrome.
