What is the definition of stress?

Stress is defined as a body's reaction to change that requires adjustment. It encompasses various physical, emotional, and psychological responses to challenging or demanding situations. When individuals encounter changes in their environment, whether external (like life events or work-related pressures) or internal (like thoughts and feelings), their bodies and minds can experience stress as they strive to adapt to these changes. This definition highlights that stress is not merely a response to negative events; it can also arise from positive changes or new experiences that require adjustment.

For example, starting a new job, moving to a new location, or even preparing for a significant life event—such as marriage—can all induce stress, as the individual needs to adapt to new circumstances. Recognizing stress in this context is crucial, particularly for those in law enforcement and other high-stress professions, as understanding its definition allows them to manage and mitigate stress effectively.
