How is stress defined?

Stress is defined as the way in which the body responds to the demands placed upon it. This encompasses both physical and psychological responses. When faced with a challenging situation, the body undergoes a series of physiological changes, often referred to as the "stress response" or "fight or flight" response. This involves the release of hormones such as adrenaline and cortisol, which prepare the body to react to perceived threats or challenges.

In understanding stress, it’s important to recognize that it is not merely an emotional reaction or a mental health condition, but rather a comprehensive physiological and psychological response that involves multiple systems in the body. This definition highlights the impact of both external demands and internal responses, encapsulating the dynamic nature of stress as it relates to individual circumstances and environmental factors.
