dunno. seems a lot of wasted water, you can't recirculate it or you'd be back to square one. maybe if it's activated with a pressure plate of sort it'd be more environmentally friendly.
Why do you think it is being wasted? It isn't being contaminated, and will eventually wind up back in the water supply.
It is definitely being contaminated and won't end up back in the water supply until it's retreated (which is not free).

#53The chlorinates created when the chlorine reacts with e.g. sweat and urine is what causes red eyes and breathing difficulties. From my experience, stay away from hotel/health club pools. These usually have saunas and jacuzzis which means people jump into the pool afterwards and contaminate it a lot... If you are doing swimming for fitness you will be inhaling a much larger volume of air, plus you will be inhaling air…
Chloramines, or combined chlorine are the by-products of free chlorine reacting with organic material. If there are too many, the pool has been improperly treated, or a huge amount of organics has overwhelmed the system. Chlorinates are things into which you've added or introduced chlorine.

> The people using these pools are generally a lot more conscientious about showering before entering the pool.
But you’re now going to face swimmer drama. Violation of some unknown, unspoken rule will result in dirty looks and jerky behavior.
I’d rather swim in pee than deal with unfamiliar serious swimmers!

If it's not washing something off, what's the purpose of it?

#56The headline is a bit clickbaity. The third paragraph starts with "In fact, chlorine is still a culprit." A more accurate title could be "Urine and Chlorine Cause Red Eyes in Pools."
I don't get it. Chlorinated water from the drinking tap, otherwise perfectly pure, smells of chlorine. And swimming pools might use much more than it's used in public water distribution, and in variable amounts- depending on how many tablets have been used, how recently, etc.

#57There is a very informative video[1] that also links to scientific papers about this phenomenon and concludes much less sensationally. Essentially, urine is a sterile substance containing %95 pure water and no living cells or bacteria. Other than the asthma inducing effects of chloramine, swimming at a public pool doesn't pose a massive threat to your health. [1]: https://www.youtube.com/watch?v=S32y9aYEzzo
While that may be the case for urine, the article pretty clearly states that fecal matter is a significant risk factor.

Why are sudden temperature changes bad? When I was a kid in the north of Scotland we'd always jump in as gradual exposure to cold water was miserable - the shock of jumping in was always quite bracing ;-) Mind you - as I doubt if it was much above 20C most of the time I doubt the temperature difference between air and water was that large!
I think the idea is that a sudden immersion in cold water when the weather is hot can cause a sudden contraction of your blood vessels which can result in a syncope. At least that's what I've always been told, but I know there's a lot of cargo culting and urban myths surrounding these topics so it's hard to know what's really dangerous and what's just superstition. For instance as a kid I've always been told that it…
Syncope == faint(ing)

When you say difficulty in breathing, do you mean that feeling that you sometimes get after being in a pool for a long time where if you take a deep breath, it kind of hurts your lungs?
That’s the feeling I get after walking or cycling in London traffic and getting a lung full of diesel fumes...
That's the same feeling most humans get when they're exerting themselves in an environment with lots of airborne particulate matter.

The cardiovascular system has to suddenly adjust its rate to keep the body warm enough. If your heart is weak, it may not be up to the task and a heart attack is possible. It might be fine for young people and people with people with peak cardiovascular health, but for older people or anyone with impaired cardiovascular health, the risk goes up.
Now, I'm thinking of all those images of old Russians going in to frozen outdoor pools, AFAIR they always climb down a ladder/steps. This might explain why.
Slowly getting in to cold water is some kind of torture to me, I always dive in. But frigid water is not my thing at all.
