What does the body’s response to stress typically include?

The body’s response to stress typically involves a range of physical and psychological adjustments, which are collectively known as the stress response. When faced with a stressor, the body activates the fight-or-flight response, which leads to various physiological changes. These may include an increase in heart rate, elevated blood pressure, and the release of stress hormones like adrenaline and cortisol. This response prepares the body to either confront or flee from the threat.

On the psychological side, individuals may experience heightened alertness and concentration, as well as emotional responses such as anxiety or excitement, depending on the nature of the stressor. These adjustments are essential for survival and can impact physical performance, decision-making, and overall well-being.

The other options do not accurately represent the typical responses to stress. While flexibility and muscle recovery are important in physical conditioning, they do not directly relate to the body's immediate response to stress. Immediate injury is more of a consequence of extreme physical stress or trauma rather than a general response mechanism. Hence, the correct option reflects the comprehensive nature of how the body actively adapts to stressors.
