Which term describes the wear and tear on the body due to prolonged stress?

The term that accurately describes the wear and tear on the body resulting from prolonged stress is chronic stress. Chronic stress refers to a continuous state of stress that persists over an extended period, affecting almost all aspects of an individual's health. When the body remains in a heightened state of alertness or stress for too long, it can lead to numerous health issues, including cardiovascular problems, weakened immune response, anxiety, and depression.

In contrast, critical incident stress typically involves reactions to a specific traumatic event, while acute stress is a temporary response to immediate threats or challenges. Eustress, on the other hand, represents a positive form of stress that can motivate individuals and enhance performance. Unlike chronic stress, eustress is generally beneficial and can lead to growth and improvement rather than detriment. Thus, chronic stress is the most suitable term when discussing the long-term effects of sustained stress on the body's well-being.
