Why do I jump around when I wanna pee?

Question

I've been noticing everyone does that and I do too. Is it something to do with muscles in your groin?

Answer 2

When it gets bad, it's a form of pain.  Many people have hyperactive reactions to pain.  It is probably due to a fight-or-flight response to a stimulus that the brain's limbic system unconsciously perceives as a threat.  Very ancient thing in our genes, this is.

Note: From what might superficially appear to be frivolous questions can come some profound perspectives.

must be something wrong with you. I don't

Answer 4

I think it has something to do with movement helping to keep you from peeing when you need to go badly.  The more muscles you move around in that area and the rest of your body, the easier it is to hold it in.

Urine is held in by two urethral sphincters, which are just little constricting muscles that seal the urethra and block the flow of urine.  The internal urethral sphincter is naturally closed off, and is something you can't control.  As urine gradually fills up in your bladder, the internal sphincter keeps it held in, and you don't notice any feelings or need to pee.

The internal urethral sphincter only holds against so much pressure, however.  Once the bladder fills up enough to put more than a certain amount of pressure on the internal sphincter, it relaxes, allowing urine to push through, which makes you feel the need to pee.  You then have to consciously constrict your external urethral sphincter, which takes more and more effort as the pressure builds.

Now, I'm thinking that general movement helps tense up that sphincter because the somatic nervous system, which controls the use of the external sphincter, also controls the use of your skeletal muscles.  So as you move your body around, especially muscles in your lower body, it helps activate that particular part of the nervous system and aid in the control of that tiny muscle.

Now, if you'll excuse me, i've gotta stop wiggling my legs and go pee.
