Why do you want to pee standing up when you take a shower? Don't be surprised, it's related to physiological factors

Recently, when I was surfing the Internet, I saw a netizen complaining about his girlfriend peeing while standing in the shower:

In response to this, female netizens in the comment section acted as if they were surprised by the rare post, and commented:

The feeling of warm urine flowing through your legs is pretty good, right? (Don’t ask me how I know, I just know it 😃!)

Why do girls like to pee standing up in the shower? In addition to the psychological feeling of "refreshing", there are more physiological factors.

How does the urge to urinate come about?

First, let's understand the whole process of urinary urge:

Urine accumulates in the bladder. When the amount of urine increases, the detrusor muscle in the bladder contracts, forcing the urine out of the urethra.

Among them, there is a "stretch receptor" in the detrusor muscle, which is similar to an intelligence officer. When urine is needed, it will send a signal to the urination reflex center of the spinal cord, and then transmit it to the brain, generating the urge to urinate.

The cerebral cortex is like a commander. After receiving the message, the cerebral cortex sends a specific signal to cause the detrusor muscle of the bladder wall to contract and the sphincter to relax, thus completing urination. In this way, the normal urination action is completed.

However, urination is a physiological process, and there are many factors that can affect the urge to urinate, such as drinking too much water, mental stress, cold weather, etc., which can all lead to the need to go to the toilet frequently.

In addition, there is another abnormal factor, that is, illness. Common diseases include urinary tract infection, male prostatitis, prostatic hyperplasia, diabetes, overactive bladder, etc. This requires going to the urology department of a regular hospital for examination and treatment.

The normal daily urine output of a person is 1000~2000ML. Usually, the urination frequency in 24 hours is more than 8 times. More than 2 times of nocturia is considered frequent urination.

Why do I have to pee when I take a shower?

When you take a shower, you hear the sound of running water and feel the warm water washing every inch of your skin, and suddenly you feel the urge to urinate. Why is this?

Conditioned reflex: The sound of running water when taking a shower is a bit similar to the sound we make when we pee, so the brain will associate this sound with "urination".

Therefore, even if there is a small amount of urine in the bladder during bathing, the urge to urinate will be stronger than usual. The same is true of whistling when holding a child to urinate.

Alternating between hot and cold makes the muscles contract: taking a hot bath can relax the muscles. When the surrounding environment becomes cold, the pores on the skin will contract, the muscles will contract, and the detrusor muscle of the bladder will also contract, which will increase the pressure in the bladder and make it easier to urinate.

Mental relaxation: When taking a bath, the brain and muscles are very relaxed, the cerebral cortex and the muscles that control urination are in a relaxed state, and the central nervous system will not continue to remind you to "hold your urine". Therefore, the ability to control urination is weaker than usual.

Therefore, fairies want to pee as soon as they take a bath. This is because bathing is so comfortable and relaxing. It is also a rare rest time after a tiring day. So men should be more understanding.

Will you get sick if you pee while standing?

Some so-called "popular science articles" seriously say that women who urinate while standing will get vaginitis, pelvic inflammatory disease, cystitis, etc. In fact, these contents have no scientific basis at all. Don't be fooled again!

👉When you urinate while standing, the urine will indeed stain the vaginal opening, but the female urethra and vagina are originally close to each other. Whether you urinate while standing, squatting, sitting, or lying down, the urine may pass through the reproductive area. This is normal.

👉At the same time, women's urethra is short and straight. Even if they cannot urinate completely while standing, there will be no urine retention in the urethra. And according to Newton's law, urine is even less likely to flow back into the vagina and bladder. Therefore, there will be no various inflammations spread on the Internet!

The only downside to peeing while standing in the shower is that it smells too bad!

Imagine that as the hot air evaporates, a faint smell of ammonia will evaporate from the urine. Uh~ people who can't accept it will indeed feel a little nauseous.

However, when it comes to peeing in the shower, everyone has their own private personal preferences. As long as you feel comfortable, you can pee however you want!
