What is the reason for all the movement when we really need to go pee? Is it a subconscious reaction to distract the mind from a full bladder, or does sloshing the pee around in your bladder make it somehow better? I would assume not, since that probably increases the physical urge that you need to go pee, but why then do we dance and hop…
Your nervous system has finite bandwidth. The extra movement and sensation signals drown out the “need to pee” signal, making it seem less urgent. It’s also why we rub the area around minor injuries to relieve pain.
