Why does the sound of dripping water make you want to urinate?

The water dripping noise , that soft and more or less rhythmic sound, even a soft tap water jet , is an excellent motivator for the bladder .In some cases it is very practical, but in others it can be a huge problem.

But what makes us react like this when we hear the water? Why do we feel like urinating when we hear it? In this article you will find out.

How the urine control mechanism works

When people urinate, urine goes from the bladder to the urethra through narrow ducts.This current is controlled by the sphincters, some muscles that act as brakes on these tubes, so that they do not reach the urethra (as if they were a tap that opens and closes).

The first of these muscles, the internal sphincter, is in the upper part of the urethra, next to the bladder, and they are automatically controlled by our nervous system.When our bladder is full, a message is sent to the internal sphincter , telling him to relax and open the floodgates.But so that the urine does not escape it is necessary that the second sphincter, the external sphincter , is under our conscious control, which allows us to keep the flow controlled of urine, canceling the demand of the body when it asks us to pee.

Running water, total relaxation and pee?

The part of our nervous system that automatically controls the internal sphincter is called the l parasympathetic nervous system (SNP).The SNP tends to be more active in moments of calm and rest , when internal sphincters want to open up and give way to bladder contents, it is likely, therefore, that the soothing sounds of running water relax us enough to make the SNP send more messages to the Internal sphincter, telling you that you can open and make way.

Why does the sound of dripping water make you want to urinate?

At this point, it is important to note that, in front of the parasympathetic nervous system is the sympathetic nervous system ( SNS), which is an independent nervous control system on which reactions such as fight or flight depend when our heart rate increases or reactions physics related to fear or thirteen months.This is important to know, since this system is also related to the contraction of the internal sphincter and tells you to stay closed.

Conditioning: Stimulus-Response

The second possible explanation of why running the sound of water makes us want to urinate is related to classical conditioning , that of dogs Pavlov. But what does this consist of?

In the 1890s, a Russian psychiatrist named Ivan Pavlov conducted experiments with dogs to show how animals learn unconsciously anticipating something important.In his experiment, Pavlov rang a bell just before feeding his dogs.I note that, after repeating the routine, the dogs began to salivate as soon as they heard the bell, without ever having seen the food before.This was because the dogs had learned an automatic response, and associated the sound of a bell with the arrival of food.

In the same way that dogs learned that After the bell came the food and began to salivate, people learn, through our experience, to associate the sound of water when urinating and thus it is difficult for us to think about other things that are not to do pis.
