How is stress defined in psychological terms?

In psychological terms, stress is defined as the body's and mind's response to challenging or demanding situations. This definition encompasses the concept that stress arises not only as a reaction to negative circumstances but also in response to any situation that requires an adjustment or adaptation, whether it is perceived positively or negatively.

Stress can trigger a range of physiological and psychological responses, including increased heart rate, anxiety, and a general sense of urgency to address the challenge at hand. Understanding this definition highlights the complexity of stress as a natural and necessary part of life that can motivate individuals to respond to their environment but can also lead to negative effects if not managed appropriately.

The other options describe states or feelings that do not align with this definition. A feeling of relaxation and tranquility represents the absence of stress, rather than its definition. Positive motivation to complete tasks may describe a constructive response to challenges, but it does not capture the broad nature of stress itself. Similarly, a state of emotional well-being indicates a balanced mental state, distinct from the definition of stress, which focuses on the response to external pressures.
