Why do we shiver during/after we take a leak?

Question

My thought is that the body is receiving a mild shock from the quick temperature change in the bladder...since the urine was nice and warm, and then it goes to empty very fast

this is very commom amongs males

Answer 1

You people are dumbasses - of course guys shiver. lol. I know that and I'm a chick.

Hell, I shiver sometimes.

Maybe takin a leak feels good sometimes, I dunno.

Good question though!

Answer 2

Low room temperature as covered parts of the body are exposed could be an obvious cause. More seriously, the shivering is an example of the human body's autonomic nervous system (ANS) at work.

We are not conscious of the ANS. It runs on automatic, hence its name, "autonomic", which literally means "self controlling, working independently". The urination reflex is relayed through the ANS. The reflex is directly related in strength to the amount of stretch of the bladder. Thus, the degree of shivering is generally related to how full the bladder is at the time of urination.

The ANS has two divisions. One is the parasympathetic nervous system (PNS) and the other is the sympathetic nervous system (SNS).

The SNS tends to keep the bladder relaxed and the urethral sphincter contracted. This is why one does not have an "accident" while one is concentrating on something else. It is true to say that the more "desperate" one becomes in response to a bulging bladder, the more the SNS acts to keep you dry.

The SNS response includes the release by the brain of chemicals doadrenal medulla catacholamines epinephrine, norepinephrine, and dopamine to bring about the necessary body reactions. When the opportunity arises to allow the parasympathetic side of the ANS to take over, the change in catacholamine production probably causes of the shivering.

Laboratory experiments which have not been undertaken would prove this beyond doubt.

In any case, at the moment of urination, there is a slight blood pressure rise and a momentary flushing or euphoria shortly after relaxing the urethral sphincter. Some find this feeling pleasurable. At such moments, some people say "ah". This same response in its most extreme forms causes fainting. All of this is the ANS doing its job.

I know what you're talking about but I'm not sure why exactly. ...and I don't think that happens to girls. Most guys do it. It's not really "shivering" but it's like a head shake. I know it's common because people do it in comedy movies when they take a pee.

My best guess is that a hard stream of urine hits a nerve ending in the 'pleasure area' and triggers this response. That 'shiver' thing is generally a physical sensation of great relief (aka it feels damn good.)

One thing for certain, it's not dangerous or any symptom of something bad.

Answer 4

I dont know about you but I have never had this problem. Probably becuz you havnt took a leak all day so it causes more and more warmness into you bladder.

Answer 5

I agree because people also shiver after throwing up.So it is likely the temperature change.

Answer 6

WHAT AN ODD QUESTION....HOW CAN YOU BODY TEMP CHANGE THAT FAST...HOW OLD ARE YOU...LOLOL, IT CAN'T BE THAT COMMON...MY HUSBAND NEVER "SHIVERS" AFTER TAKING A LEAK....DO YOU WATCH GUYS TAKE A LEAK IS THIS HOW YOU KNOW IT IS COMMON???
