Psychological stress causes the frequent urge to urinate
Clinical and experimental evidence demonstrates that psychological stress can lead to lower urinary tract dysfunction, resulting in symptoms such as an increased frequency of urination.
The claim is specific, falsifiable, and directly tested by multiple empirical studies and reviews. Papers [3], [10], and [11] explicitly demonstrate in both human clinical contexts and animal models that psychological stress (such as water avoidance stress or repeated variate stress) induces bladder overactivity and increased voiding frequency. Paper [9] links chronic psychological stress to bladder conditions characterized by urinary urgency and frequency via inflammatory pathways. Because the evidence uniformly supports the link between psychological stress and frequent urination without contradictory papers, the balance verdict is SUPPORTED.

Demonstrates in a mouse model that psychological stress significantly increases voiding frequency, which can be managed with standard overactive bladder medications.
