The smell of chlorine provides information about hygiene in the bathroom
Whether urine, hair, make-up remnants of sweat: when you think about what could be in the pool of the indoor pool, some of your stomach turns. If you go swimming regularly, you have to come to terms with the fact that there is probably no pool without a pee and other unpleasant substances. However, the disinfectant chlorine can help. Because this decomposes the urine, which creates the characteristic swimming pool smell.

Disinfectant Chlorine decomposes nitrogen from urine or sweat
A visit to the swimming pool is not for everyone, because the possible "bath additives" such as pee, skin flakes or hair cause disgust for many people. "It doesn't matter, the water is chlorinated!", Enthusiastic swimmers often reply and refer to the disinfectant effect of the chemical chlorine, which is used to keep the water in the pool clean. But how can I tell whether the pelvis is really free of unpleasant substances?

It cannot be seen with the naked eye how many people have already peed in the bathroom. Instead, trust your own nose. Because the typical swimming pool smell does not come from chlorine alone, but only arises when the chemical decomposes urine.

Chemical is usually odorless
"Chlorine is initially odorless," explains Michael Solić, press spokesman for Stadtwerke München and its baths, in an interview with the magazine "Focus". "If chlorine meets nitrogen, such as urea, creatine and amino acids from urine, chlorine compounds, the so-called chloramines, are created, and with it the well-known swimming pool smell," the expert continues. So it can be said: The more urine gets into the pool, the stronger the chlorine smell in the hall.

This may sound repulsive, but according to Solić the chloramines are not harmful to health. Potentially harmful waste products also arise from the decomposition of urine with cyanogen chloride and nitrogen trichloride - but only in such small quantities that they pose no danger. In addition, everyone would react differently to the chemical. The disinfectant can be used to decompose nitrogen from urine or sweat, but other substances such as dandruff, remains of body lotion or hair care products are not attacked. The filter systems have to take on this task. "Together with fresh water that is constantly being supplied, filters and chlorine can ensure clean water in the pool," emphasizes the pool expert.

Avoid redness of the eyes by showering thoroughly
And where do the red eyes in the swimming pool come from? As the US Water Quality and Health Council explains, "too much chlorine in the water" is not responsible here either. Instead, the typical reddening of the eyes would also only result from the chemical reaction of the substance with urine and sweat. Swimming pool visitors can do a lot themselves to keep the water clean and avoid red eyes. It is particularly important to shower off thoroughly before swimming to remove residues of care products, dirt particles, sweat and traces of faeces. In addition, of course, you should not urinate in the water, but rather take a short break and visit the toilet. (No)
