According to recent studies and surveys, a significant portion of adults—roughly 40% to over 50%—admit to peeing in swimming pools. A 2025 survey found that 53% of adults confessed to this, effectively making public pools "shared urinals". Even Olympic swimmer Michael Phelps once mentioned it was a "normal thing" for swimmers.
What percentage of people urinate in pools?
Surveys show that between 40% and 53% of adults admit to peeing in swimming pools. However, Canadian scientists testing actual pools found that 100% of the pools tested contained urine, meaning the real percentage of people who do it is likely much higher.
What is the 21 second pee rule?
The "21-second pee rule"—also known as the Universal Law of Urination—is a scientific observation that almost all mammals weighing more than 3 kg (including humans, dogs, and elephants) take roughly 21 seconds to empty their bladders.
What happens when someone urinates in a pool?
When urine enters pool water, it reacts with chlorine to produce chloramines — chemical compounds that reduce the effectiveness of chlorine as a disinfectant. This reaction can cause eye redness, skin irritation, and respiratory discomfort for swimmers.
How much urine is in a typical pool?
The average Olympic-sized pool contains about 600,000 gallons of water or more, which means the pool has a 0.05% concentration of pee. That's about one part per 2,000. If the pool is well-maintained, the water will be clean and free of harmful bacteria.
How Much Pee is in the Pool You Swim In
How can you tell if there is pee in your pool?
One of the most common pool myths is the one where parents tell the kids they put a chemical in the water that will turn green or purple (pick a color) if they pee in the pool. That is not remotely true (even if we might kind of wish for it), nothing of the kind exists.
Is peeing every 2 hours normal?
Peeing every 2 hours can be completely normal if you are very active or drinking a lot of fluids, but it is on the higher end of typical frequency. Most healthy adults urinate 6 to 8 times in a 24-hour period, which averages out to every 3 to 4 hours during the day.
Is it rude to pee in the pool?
While many people might be aware that it is considered “bad manners” to urinate in a swimming pool, kids and competitive swimmers alike may not always follow this rule. In fact, during the 2012 Summer Olympics, several athletes made headlines by admitting that this frequently happens.
What is a cowboy pool?
A cowboy pool (also known as a stock tank pool) is a large, galvanized metal trough that has been repurposed into a backyard swimming or soaking pool. They offer a rustic, budget-friendly, and space-saving alternative to traditional in-ground pools.
What is the 25/10 rule in swimming?
The 25:10 rule states that if a child is unable to swim 25 meters continuously (no stopping) and unassisted, then a parent needs to remain in the water with them within 10 feet of the child.
How often should a 70 year old urinate?
For most people, the normal number of times to urinate per day is between 6 – 7 in a 24 hour period. Between 4 and 10 times a day can also be normal if that person is healthy and happy with the number of times they visit the toilet.
Which animal can hold pee for 8 months?
Wood frogs in Alaska can hold in their pee for eight months. Apparently, they do this to help them stick it through the region's long winter season.
How to stop people from peeing in the pool?
Facility Managers should consider two ways to prevent pee in the pool. First, schedule short breaks to encourage people to exit the water. For example, a 10 minute “adult only” swim time or an out-of-pool activity every hour encourages people to exit the pool and use the bathroom.
Why do I pee more in the pool?
The urge to pee while swimming is primarily caused by immersion diuresis, a physiological reaction where your body interprets water immersion as excess fluid.
Can peeing in a pool cause a UTI?
Yes, peeing in a pool can contribute to developing a Urinary Tract Infection (UTI), although it is not the only cause. While chlorine kills most bacteria, high amounts of urine can reduce its effectiveness, allowing bacteria to thrive in the water and potentially enter the urinary tract.
Can you tell if someone peed in your pool?
No, you cannot immediately tell if someone peed in your pool using a chemical that changes color, as that is a myth. However, high chloramine levels causing a strong, pungent "chlorine" smell, eye irritation, or a specifically tested increase in artificial sweeteners like acesulfame potassium can confirm the presence of urine.
What happens if someone urinates in a pool?
Peeing in a pool creates chemical byproducts that deplete chlorine levels and produce irritating compounds. The chemical reaction forms chloramines (like trichloramine), which cause red eyes and breathing irritation, and cyanogen chloride, a volatile and toxic byproduct. The strong "chlorine" smell often associated with indoor pools is actually the smell of these byproducts.
Is peeing in the pool a crime?
While there is no specific criminal law strictly against peeing in a pool, doing so in a public place can lead to citations for indecent exposure or creating a public nuisance. In many areas, such as Maine, specific public health statutes outright prohibit bodily fluids in aquatic facilities.
Can I pee 20 times a day?
So… how often is “too often”? Most guys go about 6 to 8 times a day. That's the average. If you're clocking more than that, say you're a urinating 20 times a day, it's time to pay attention.
Why does urine smell strong?
Urine typically has a mild smell, but it can become strong due to dehydration, diet, or certain medical conditions.
Is clear pee good?
Occasional clear pee is completely fine and simply means you are well-hydrated. However, consistently colorless urine is not ideal. It often indicates overhydration (drinking too much water), which can dilute your body's essential electrolytes and potentially lead to a dangerous imbalance called hyponatremia.
Can public pools detect if you pee?
Though there's no specific chemical that detects urine in a pool and changes colors, scientists have been able to estimate just how much urine might be in the average pool.
What happens if a kid poops in a swim diaper in the pool?
Research shows that even though swim diapers and swim pants might hold in some solid feces (poop), they are not leak-proof. Swim diapers can delay diarrhea-causing germs, like Cryptosporidium, from leaking into the water for a few minutes, but swim diapers do not keep these germs from contaminating the water.
Why do people put baking soda in their swimming pools?
Baking soda (sodium bicarbonate) is used in swimming pools to raise and stabilize total alkalinity and, to a lesser extent, increase pH. By balancing these levels, it prevents the water from becoming acidic, protects pool equipment from corrosion, stops pH fluctuations, and helps your chlorine work more effectively.
