The nervous system releases neurotransmitters in the body called catecholamines in an effort to restore blood pressure. This creates a mixed signal between the two components of the sympathetic nervous system, which causes you to shiver when you pee.
Pee shivers might be due to a sudden drop in body temperature, or mixed signals in your nervous system. They are harmless. This doesn't mean you should ignore all unusual occurrences that happen during urination.
In neurourology, post-micturition convulsion syndrome (PMCS), also known informally as pee shivers, is the experience of shivering during or after urination. The syndrome appears to be more frequently experienced by males.
The most well-known and easily recognizable symptom of a UTI is pain or discomfort when urinating. Oftentimes, this pain manifests itself as a tingling or burning sensation, and such pain indicates there is bacteria in the urethra.
Peeing can also be pleasurable because it relieves tension and can make a person more comfortable, especially if they have held in urine for some time. Some report that the feeling of release while urinating is so intense that they have an orgasm or an orgasm-like sensation.
This gives the physiological capacity of the adult male and female as 500 ml, and notes that there is probably no inherent difference between male and female.
Holding your urine for too long can weaken the bladder muscles over time. This can lead to problems such as incontinence and not being able to fully empty your bladder. Holding your urine for extremely long periods of time can also cause urinary tract infections due to bacteria build-up.
The short answer: It's fine to pee in the shower. That's according to Jamin Brahmbhatt, MD, PUR Clinic urologist and Assistant Professor at UCF College of Medicine in Florida, who knows more about urine than most people.
A healthy bladder can hold about 2 cups of urine before it's considered full. It takes your body 9 to 10 hours to produce 2 cups of urine. That's about as long as you can wait and still be in the safe zone without the possibility of damaging your organs.
Unlike foods, water can be “digested” in as little as 5 minutes. Excess water leaves your body through urination and feces but is also excreted by sweating. Your body uses water for many of its daily processes, and since it passes through your body so quickly, it's important to stay hydrated.
myth. urinary bladders of both sexes have same capacity of storage.
Urinary bladder and urethra
The urinary bladder can store up to 500 ml of urine in women and 700 ml in men. People already feel the need to urinate (pee) when their bladder has between 200 and 350 ml of urine in it.
The truth is, there are a number of reasons why men might opt to sit down—and research suggests that more guys do it than might be expected. Data—admittedly, data from 2007, but hey, this isn't studied too often—shows that 42 percent of married men sit down to urinate, presumably due to spousal pressure.
Pressure in the bladder causes this feeling, which should disappear after a person urinates. However, some people experience this pressure constantly, and it may feel like an ache. This is not normal and is likely caused by interstitial cystitis. This condition is sometimes known simply as bladder pain syndrome.
If the infection spreads to your kidneys, symptoms may include: Chills and shaking or night sweats.
Bladder spasms can cause cramping, burning pain as your bladder muscles involuntarily contract, and you'll likely also feel an urgent need to urinate. Bladder spasms happen suddenly and can cause urine to leak from the bladder, which is called urinary incontinence.
If you're experiencing an upper urinary tract infection, the symptoms are more flu-like and may include: fever, chills, nausea and vomiting.
