Presumably, all men have had this experience in their lives: a wave of urine comes, so you rush to the urinal in the toilet and start to pour out.
As the bladder is emptied, you slowly let go of your nervous emotions, and when you are still worried about the unfinished business and ready to lift your pants, you will involuntarily shiver, and your whole body will be like electricity.
In fact, not only male friends, but also some women and small babies in life will have similar symptoms, but the probability of male appearance is greater.
It should be noted that this is not a signal of physical illness, but what is clinically called "post-urination convulsive syndrome", which is also referred to as urinary fibrillation, and its most typical manifestation is that after urinating, the human body will shake violently or the whole body.
Relevant research surveys show that the reason why men have urinary fibrillation is mainly related to the following two aspects:
1. Heat loss
Humans are actually typical thermostatic animals, in daily life, a healthy adult body temperature is maintained at about 36-37 ° C. The reason for this is that we have a very perfect body temperature regulation mechanism inside the body.
For example, when the weather is very cold, suddenly into the cold air you will suddenly fight cold war, shivering, which is actually the performance of body temperature regulation;
95% of the urine stored in the bladder is water, and the rest is a small amount of metabolic waste. Moisture, in fact, plays a role in maintaining heat in body temperature regulation. When men hold back urine for a long time, these waters are maintaining your calories. Suddenly the entire urine is excreted, which means the loss of heat in the body;
Moreover, during the process of urinating, a part of the body is also exposed to the air. As warm urine continues to drain, the body temperature briefly loses its balance, causing the body to tremble uncontrollably. However, the thermoregulation center then immediately begins to work, so it is a normal physiological response that does not have any impact on health.
2. Neurological effect
All the actions and thoughts of the human body are actually dominated by the brain and conducted by the nervous system. The continuous filtering of blood by the kidneys and the storage of urine in the bladder are supervised by the autonomic nervous system.
The so-called autonomic nerve is actually the human peripheral nervous system, which is also the automatic control center that regulates the body's functions. The scope of its involvement includes regulating body temperature, heartbeat and other aspects;
However, it should be emphasized that urination is not actually an autonomous act, but an act controlled by the human consciousness. When urine is constantly produced in the kidneys and stored in the bladder, it stimulates the body's urinary reflex. If you hold urine for too long, you will stimulate the sympathetic nerves, resulting in a conditioned reflex in the nerves and a violent appearance of urine tremors.
In addition, the physiological structure of men and women is different, in the process of urination, it is inevitable to cause irritation to the nerves at the end of the penis, sometimes this stimulation is manifested as a tingling sensation when urinating, and sometimes it is a sudden appearance of urinary tremor.
All in all, urinary fibrillation is the result of the loss of body temperature and nerve action, which is a normal physiological response.
If you don't want to let the urine fibrillation occur repeatedly, then what you need to do is to try not to hold urine, when you feel that the bladder is full and there is a sense of urine, you should solve the problem as soon as possible, which will not only reduce the probability of urinary fibrillation, but also have certain benefits for the health of the urinary system.
