Should you shower before swimming in a public pool?

I was lucky enough to go to a school that has a swimming pool. I've been totally indoctrinated into the idea of showering before swimming. And yes, it had less chlorine in than any public baths I've been in. I have to wear goggles in them.

I'd be embarrassed to walk out of the changing room without having had a shower. Filthy ****s who don't.

I have seen some people abroad shower before they go in the sea. That's a bit weird.
 
I don't get this, it's not like water just vanishes once it's used (unless of course it evaporates but then it comes back as rain), it gets cleaned and put back into the water supply, we're not living in a 3rd world country where water supply is an issue

It takes a lot to clean the volume of water that we use and that's the issue here, not the contaminated water itself. That we have in abundance.

It takes time, money and energy to treat it after use.
 
But if the Oceans are rising, we should be using more water to counter the rise, if it's in use it can't be flooding our homes :D
Now this is the kind of bro-science I can get behind. Quick, get this man a spot on GBeebies News!
 
could be marginal how much 'dirt' you sweat into the pool if you are swimming, versus what was imported on an unshowrered body

How much do we sweat? An average person sweats between 0.8 to 1.4 liters (roughly 27.4 to 47.3 oz.) per hour during exercise.
...
The easiest way to measure your sweat rate is to weigh yourself without clothes on before exercising for one hour. After an hour of exercise, return home, strip down and weigh yourself again. Assuming you did not use the toilet or consume any fluids during exercise, your weight loss is your sweat rate.
 
I might not ever get in a swimming pool after reading this thread. Reminds me of when I went swimming at school and when walking through the changing area something got stuck to my foot.. it was someone's discarded plaster, complete with blood UGH!
 
The chlorine in the water should change colour for the detection of pubes, fat, urine, feces, semen and vaginal batter.

And then folk can make their own judgement.

By that argument you would never swim OR have a bath, just a shower?
