What is the definition of stress in relation to the body's response to change?

Stress is defined as the nonspecific response of the body to any demand for change. This definition captures how stress represents a broad range of physiological and psychological reactions that occur when an individual faces various demands, whether they are positive or negative.

When the body encounters a situation perceived as challenging or threatening, it triggers a complex series of responses, often involving the release of stress hormones such as adrenaline and cortisol. These responses prepare the body to confront or flee from these challenges, encompassing all forms of demands—whether they arise from physical threats, emotional challenges, or contextual changes.

This definition is inclusive of the diverse stimuli that can cause stress, emphasizing the idea that it is not limited to specific environmental challenges or the ability to adapt, but rather includes all responses triggered by any demand. By understanding stress in this way, individuals can better address and manage their reactions to various life changes and pressures.
