A research team at the University of Alberta in Canada published a paper in 2017 that estimated how much urine gets mixed into swimming pools by measuring concentrations of the artificial sweetener acesulfame potassium. The findings sparked a wave of posts on 5ch sharing experiences and opinions about pool and bath etiquette and hygiene.

“Sweetened Swimming Pools and Hot Tubs,” a paper published in 2017 in the journal Environmental Science & Technology Letters by researchers at the University of Alberta in Canada, quantified the amount of urine mixed into swimming pools using artificial sweeteners.

LEGENDARY THREAD INCOMING━━━━━━(°∀°)━━━━━━!!!!
This has zero breaking-news value, this is from 2017.
Just go before you get in the pool.
Isn't the pee concentration probably way higher in the ocean?

Nah, the ocean's huge though.

Toshimaen's pool, which packed in like 50,000 people and is sadly gone now, must have been something else. (Toshimaen was a famous Tokyo amusement park that closed in 2020)

That wasn't a pool, that was a potato-scrubbing tub. (Japanese slang for a spot so packed with bodies it looks like potatoes being scrubbed together in a barrel)
There are probably people out there who'll go their whole lives thinking that's what playing in water is.

People who pee in the bathtub —
there are surprisingly a lot of them.

Don't casually generalize your own messed-up daily habits to everyone else.

Peeing in the pool is basically normal — honestly I don't even remember ever using the pool restroom or seeing anyone else use it.
At outdoor pools, bugs are drowning all over the place anyway,
and at public pools you'll sometimes even see poop floating.

That's a joke, right? I hear this kind of thing a lot on 5ch, but
I want to believe people who actually pee in the pool are a tiny minority.

Isn't a fair chunk of it probably sweat too?
>>30
There are a lot of serious swimmers out there,
so probably about as much sweat pours in as from track-and-field athletes.

If anything, there's more sweat in there than urine.

I think there are some things in this world you're better off not knowing.

Right?
Same goes for hot springs and spas.
After I've had a nice, satisfying pee, I watch the next guy come in and wash his face with the water and think, ugh, poor guy.
That's why I never take a spot downstream in the bath.

Is it true or false that your eyes turning red after school pool time
isn't actually from the chlorine, but from the pee?

Pools are huge, but
if you tested somewhere that isn't a natural hot spring, or a regular public bathhouse in Japan, the numbers would probably be way worse.

If it's a fresh-flowing natural spring source, no problem.
Even circulating baths filter the water, so the pee gets removed.

I guess this assumes the concentration of that acesulfame-whatever in urine is the same for everyone?
Got stuck behind a slow old man or woman at the ward pool and literally saw a heat-shimmer effect coming off them.
Never going back again.

That's like a phantom pregnancy or something lol

It's Bakarhythm's fault that peeing in your own bathtub for the guilty thrill became a nationwide thing — he said it felt good on TV and now the whole country's got bathtub-pee people. (Bakarhythm is a well-known Japanese comedian)

Remember all those people who used to smugly lecture that washing your body before entering the bath is proper manners? They've all disappeared.
Guess they finally figured out that peeing after you get out is the objectively correct move.
Blindly trusting Japanese people's civility and good nature just makes you the fool.

Ever since going to the beach and having the beach-hut staff point out where the restroom is, I've started thinking, do I really need that information?

It'd be hilarious if the ocean itself had a sign saying 'restroom here.'

Still, you should at least rinse off around your butt and privates before getting in.
I've actually seen someone with a piece of tissue stuck to their butt. >>83

How does that translate into a Japanese school's 50-meter pool?

Don't you mean Osaka, not Japan? (a jab implying Osaka's standards are on another level)

So there's pee mixed into the water supply source too?

Astronauts purify and drink their own pee to save water in space. It's basically a perpetual motion machine.

Even natural spring water welling up from underground can be so contaminated near ranches that locals won't drink it, and water flowing through nature is often full of bugs, animal carcasses, and viruses — always boil it first.

It reached up to 571 times the level found in the tap water that serves as the source (6–15 ng/L).
Hmm, so is the ocean actually safer to swim in than the pool?

The total volume of seawater is like 500 trillion times the water in a 50-meter pool!!
