What physical sensations may characterize agoraphobia?

Feeling hot and dizzy is a common physical sensation associated with agoraphobia, particularly because it often co-occurs with panic attacks and anxiety. Individuals with agoraphobia may experience intense feelings of fear in situations where they perceive themselves to be vulnerable, such as in open spaces or crowded places. This fear response can trigger various physiological reactions commonly seen in anxiety, including increased heart rate, sweating, and dizziness. These sensations are part of the body's fight-or-flight response, which is activated in stressful situations.

The other options do not accurately reflect the typical physical sensations associated with agoraphobia. Chronic fatigue can be linked to anxiety but is more generalized and not specifically tied to the heightened arousal that characterizes the panic responses. Panic attacks occurring only at night would be atypical, as they can happen at any time, often triggered by specific events or environments. Constantly checking one's heart rate may reflect anxiety but is more of a behavioral manifestation rather than a physical sensation. Thus, the sensations of feeling hot and dizzy are the most representative of the experience of someone struggling with agoraphobia.
