This phenomenon is usually called urinary tremor and urinary shock. In the medical world, it also has a special term called “post-urinary convulsion syndrome” (PMCS), which sounds like a disease, but this is actually a normal physiological phenomenon of human beings. And why the human body has this phenomenon, in fact, scientists can not give a 100% affirmative answer, but a hypothesis based on the autonomic nervous system is widely accepted by the medical community.

This hypothesis suggests that urinary turbulence is actually caused by the switching of the autonomic nervous system in our body. When our bladder accumulates a lot of urine and wants to go to the toilet and can’t get on it, then your sympathetic nerves will be activated, because at this time you will feel nervous, restless, and you will need sympathetic nerves. Inhibit your bladder contraction and maintain the tightness of the urethral sphincter, so that you don’t really pee in front of the public, and because of the sympathetic excitation, your blood pressure will be higher than usual.

Then when you finally rush to the toilet to begin liberation, the autonomic dominance is ready to be given to the parasympathetic nerve. Once the sympathetic nerve is suppressed and the parasympathetic nerve is activated, your bladder will begin to contract, and the urethral sphincter will also Relaxed and synergistically, the urine pours out.

But at this moment, interesting things happen. Due to the strong activation of the parasympathetic nerves, the result of your overall relaxation will cause physical changes such as a sudden drop in blood pressure. Such physiological changes are detected by the brain and may be reflective. Inducing the activation of the sympathetic nerves, trying to maintain the state of the autonomic nervous system, so you will have a performance similar to goose bumps, resulting in a muscle shake response like a whole body.

The above is the physiological explanation that the medical profession believes is most likely to cause urinary tremors. However, there are many other related hypotheses. For example, some scholars believe that urinary turm may be the reaction mechanism of the body to “warm-loss” because with urine This warmth is discharged from the body, which may cause the sympathetic nerve to suddenly activate, which causes the muscles to tremble and produce heat to maintain body temperature, thus causing urinary turbulence.

Therefore, although scientists can not completely determine the cause of urinary tremor, no matter which hypothesis is basically considered to have a close relationship with the switching of the autonomic nervous system of the human body, in short, it is a normal physiological phenomenon of human beings.
