Severe anxiety often triggers a range of physiological and psychological symptoms due to the body's response to stress. Among these, urinary frequency is a common symptom. This occurs as a result of the activation of the sympathetic nervous system, which can lead to an increased need to urinate. The fight-or-flight response associated with anxiety causes various hormonal changes that can affect bladder function and increase urine production.

In contrast, while dry mouth can also occur with anxiety, it is not always as pronounced or specific as urinary frequency in cases of severe anxiety. Increased problem-solving abilities and the ability to relax are generally not associated with high levels of anxiety; instead, anxiety typically hampers cognitive functions and relaxation. Understanding the physiological responses to anxiety can help in identifying its symptoms better, allowing for more effective management strategies in clinical settings.
