How is stress defined in terms of response?

Understanding stress as a response involves recognizing it as the body's reaction to changes in the environment or internal state. This definition encompasses both positive and negative stressors that can impact an individual. When faced with a change, whether it's a challenge or a demand, the body reacts physiologically and psychologically to cope with that change.

This response typically involves a series of physiological changes, such as the release of stress hormones like adrenaline and cortisol, which prepare the body to confront or adjust to the new circumstances. Stress, therefore, is not limited to negative experiences; it can also arise in situations that require individuals to adapt, such as taking on new responsibilities or facing unexpected events.

While the other options touch on aspects related to stress, they do not provide a comprehensive definition that captures the essence of stress as a response to changes. They may highlight certain situations or perceptions associated with stress but fail to encompass the broader physiological and psychological reactions involved when an individual experiences stress.
