Which of the following is a symptom of moderate anxiety?

Moderate anxiety can manifest through physical symptoms that are often related to heightened arousal and responsiveness of the nervous system. Palpitations, which refer to an increased awareness of one's heartbeat, are a common symptom experienced during moderate anxiety. This symptom typically arises as the body prepares to deal with perceived threats, leading to an increase in heart rate and awareness.

While other symptoms such as tremors, chest pain, and fear of dying can also be associated with anxiety, palpitations are more consistently linked to moderate anxiety, reflecting the physiological response typical of this level of anxiety. In this context, palpitations specifically highlight the cardiac component of anxiety, making it a characteristic feature that indicates the individual is experiencing moderate anxiety.
