What physiological changes occur during an anxiety response?

The correct response highlights that during an anxiety response, there is a notable increase in both heart rate and muscle tension. This physiological reaction is primarily a part of the body's fight-or-flight response, which is activated in response to perceived threats or stressors. When a person feels anxious, the body releases stress hormones such as adrenaline and cortisol, which prepare the body to either confront or flee from danger. This results in an elevated heart rate as the heart pumps more blood to the muscles and vital organs, providing them with the necessary resources to react quickly. Simultaneously, muscle tension increases as the body prepares for action, making the muscles ready for either defense or escape.

Understanding this response is important for recognizing how anxiety manifests physically, which can aid in developing effective coping strategies and interventions for those experiencing anxiety. In contrast to the other options, which suggest either a decrease in physiological activity or no change at all, the correct answer accurately reflects the body's heightened alertness and readiness during anxiety.
