In the past, swimming pools were reserved for the rich as they were only available in luxurious holiday hotels and fancy homes; very few people could afford to visit them. Thankfully, every dynamic affecting their accessibility has changed, and they are now almost everywhere globally. Swimming has also evolved as a sport, with the likes of Michael Phelps making a name for themselves in Olympic competitions. Here, we discuss some random swimming pool facts to make your day.

In 1926, the American Public Health Association (APHA) released a handbook requiring men not to wear clothes in swimming pools. On the other hand, women were required to wear the “simplest” swimsuits. In 1962, the APHA abandoned the rule because of pool chlorination.

2. Some Germs in Swimming Pools are Chlorine-Resistant

3. An American Economist Believes Swimming Pools Are More Dangerous to Children Than Guns

Steven D. Levitt is an American economist and co-author of the best-selling book Freakonomics. Through his publishing, Levitt believes a swimming pool is more dangerous than a gun. He believes that if a home has both a gun and a swimming pool, the latter has a higher risk of killing a child. People are more cautious with firearms, and that’s why they are stored in a safe or vault. However, swimming pools are just sitting in the backyard, where disaster can strike at any minute.

4. There is No Urine Indicator Dye for Swimming Pools

According to a report released in 2015 by the National Swimming Pool Foundation, about half of the Americans involved in the survey believed there is a urine indicator dye that can detect pees in swimming pools.

As such, there is no urine indicator dye – the whole thing has always been a myth.
