Basic Corrections Officer: Certification Study Guide

Fatigue is a common physical symptom of stress that can manifest after a critical incident. When an individual experiences a stressful event, the body responds by activating the stress response system, which can lead to a feeling of exhaustion as the body works to recover from the heightened state of alertness. This prolonged activation can deplete energy levels, resulting in fatigue. It's also important to recognize that stress can hinder the body's ability to rest and recover, leading to further physical and mental tiredness.

In contrast, increased flexibility and improved concentration typically do not arise from stress; instead, they may suggest more positive states of physical and mental health. Mental clarity is often compromised under stress, as stress can cloud thinking and hinder decision-making processes. Each of these aspects illustrates how stress interacts with the body's functions differently, highlighting the prevalence of fatigue as a significant response to stress following critical incidents.
