It's totally safe to let your pee sit in the bowl, BTW “Unless you have a urinary tract infection, your urine is sterile. Even if it isn't, municipal water contains residual chlorine that can kill pathogens introduced into it.”
There are important reasons you should flush after using the restroom, such as being able to avoid bathroom germs that could make you sick. Although some individuals may flush the toilet out of habit—or at least use one that automatically flushes—not everyone does it.
Urine does contain bacteria, though it's remarkably clean compared to, say, saliva, which is teeming with microorganisms. So, while your pee isn't pristine, it is clean enough to leave in your toilet for a few hours.
A frequent cause of smelly drains and dirty toilets are urine sediments. Urine scale occurs as urine particles build up on the porcelain. As hard water evaporates, it leaves behind calcium and magnesium deposits which combine to form limescale.
No, you cannot completely fill a conventional household toilet with urine or any other liquid. The drain of a toilet is configured so that the contents will siphon out automatically from the weight of the water before the water reaches the brim.
If urine is left at room temperature after sometimes it will become slowly alkaline due to bacterial growth. After keeping the urine on the table at room temperature become alkaline due to the urea-splitting enzyme by the bacteria.
The urine smell in restrooms is typically generated by the urine that ends up in places other than in the bowl. This material — be it on toilet surfaces or on the floor and baseboards, then becomes a feeding ground for bacteria. The resulting combination, coupled with time, never smells good.
Urine nutrients become pollution when they enter the watershed. In the US, the nutrients in urine often pass through wastewater treatment plants and into rivers, lakes, and bays. Once in the aquatic environment, excess nutrients (particularly nitrogen and phosphorus) can cause harmful algal blooms (HABs).
The World Record for the longest pee is 508 seconds.
“Usually I recommend that you empty your bladder every three hours, whether you have the urge to go or not,” says Nazia Bandukwala, D.O., a urologist at Piedmont. “It's important to do that so you're not retaining too much urine in your bladder.”
You see, when you don't clean yourself down there after peeing, the urine droplets stuck in your pubes get transferred to your underwear. This gives rise to a foul odour. Moreover, it also gives birth to bacteria in your underwear, increasing the risk of urinary tract infections (UTI).
“So it's wisest to always wash with soap and water even after urinating. Neither plain water nor alcohol hand sanitizers are effective at removing fecal material or killing bacteria in fecal material.” According to the Centers for Disease Control and Prevention, handwashing can prevent various illnesses and infections.
Trimethylaminuria (TMAU) is an uncommon condition that causes an unpleasant, fishy smell. It's also called "fish odour syndrome". Sometimes it's caused by faulty genes that a person inherits from their parents, but this isn't always the case. There's currently no cure, but there are things that can help.
The sense of smell does vary among individuals, and some people may notice a mild smell to their urine that is not typically offensive in nature. The pungent odor of stale urine (think of a busy and dirty public restroom) is likely due to the presence of volatile organic compounds, or VOC's, which are present in urine.
Upstream bacterial migrations often occur where liquids flow in one direction, such as the human urinary tract and intravenous and urinary catheters. How far and how fast bacteria can swim upstream has long been poorly understood.
Any bacteria or cells present in a urine sample kept at room-temperature for more than one hour will continue to use glucose (sugar) in the urine. This may result in a falsely decreased urine glucose measurement. Also, bacteria produce ammonia which makes the urine more alkaline (increases pH).
Although holding your pee doesn't directly cause a urinary tract infection (UTI), not emptying your bladder can allow bacteria to multiply within the bladder. This is because passing urine helps to flush out the bladder and the rest of your urinary tract.
The flushing toilet provides a comfortable, safe and hygienic method of sewage disposal. However, not flushing the toilet bowl or urinal after use results in dire consequences. Open sewage smells bad and attracts pests such as flies which can carry disease-causing germs.
Prophylactics, or condoms, are another common item many people flush down their toilets because it seems like the most convenient option for disposal.
