What is a physiological response to stress?

A physiological response to stress involves the activation of the body's stress response system, primarily the fight-or-flight response. This response is characterized by a sudden increase in specific hormones, particularly adrenaline (epinephrine) and cortisol. These hormones prepare the body to react quickly to perceived threats by increasing heart rate, enhancing energy production, and improving blood flow to muscles. This physiological change is intended to help an individual cope with stressful situations effectively.

In contrast, decreased mental alertness and reduction in heart rate are not typical physiological responses to stress; rather, they may indicate a state of relaxation or depletion. An increase in harmony and balance suggests a positive emotional or physical state that is opposite to the heightened arousal seen during stress. Therefore, the increase in specific hormones is the most accurate representation of how the body physiologically responds to stress.
