Most of the Russian population lives in cities. But not in every metropolis or small cozy city on a hot day you can swim in a lake or river. But swimming is good for health. And what to do to those who cannot imagine their life without bathing? Only one way out - to go to the pool, the benefit of them in the cities is more than enough. Doctors recommend visiting the pool at least once a week. Swimming is the prevention of many diseases, moreover, it relieves emotional stress, significantly reducing stress. Nevertheless, scientists warn that a visit to the pool may be hazardous to health. But why?
So, you go swimming in one ofpublic pools located nearby. Note that for your and public safety, before visiting the pool, you need to see a doctor who will check your health and confirm the absence of fungal diseases (in case you find any, you can return to the pool after treatment). Having received a certificate, you can safely go for a swim.
The dangers of the pool you go to
The water in the pool, as you know, is chlorinated. And scientists still do not have a consensus on how safe it can be in such water. Some experts say that chlorinated water contributes to the development of bladder cancer and provokes lung diseases. Others refute these claims, calling them insolvent. So who is right?
To dot all the "and", was heldexperiment. In the role of experimental rats. Rodents were divided into two groups - some for three months, swimming for a long time in chlorinated water, and others in non-chlorinated. The results were not long in coming. In rats that bathed in water with the addition of bleach, their eyes and skin reddened. During the experiment, hair began to fall out in some animals. Needless to say, nothing happened to rats that swam in non-chlorinated water.
Let's discuss the creepy results of this experiment in our Telegram chat.
I really hope that nothing terrible with a persondue to prolonged exposure to chlorinated water does not occur. In fact, swimming in the pool is recommended no more than 30 minutes per visit. Twice a week, I do just that, and it seems that I have not yet turned into a sea monster.
What microbes live in pools?
Well, it’s good that your skin does not turn red, buthair does not start to fall out, stay in chlorinated water is reduced to 30 minutes a day. As you know, bleach is added to exterminate all the bacteria and germs present in public pools. And yet, despite the turquoise color of the water and various disinfectants, microbes can enjoy swimming in the pool besides you.

When bathing, viruses and bacteria get intomucous membranes and on the skin of swimmers. Among the most common microbes are adenoviruses, which cause conjunctivitis and pharyngitis. According to the World Health Organization, bathing in a dishonestly cleaned pool can lead to diarrhea and colitis. And also catch a parasite named Giardia intestinalis - thanks to his efforts, you may experience cramps, diarrhea, and nausea.
What about heated pools? Alas, when the water is hot, for example, as in a Jacuzzi or spa, there is a risk of multiplication of various types of bacteria: for example, the genus Pseudomonas aeruginosa, which cause otitis media, or the genus Mycobacterium, which cause pneumonia.
Are pools safe for health?
And yet, all of the above is not a reasondeny yourself the pleasure of swimming. A variety of microbes in most cases die from exposure to chlorine or bromine and while maintaining an appropriate level of pH (pH). To calmly visit the pool and not worry about anything, you need to make sure that the processing of pipes and maintaining the proper amount of disinfectants in your pool meets all the necessary requirements.
In summer, all pools go for a break, which inlasts two months on average. During this time, the pipes are cleaned, equipment checked, and, if necessary, repairs are carried out. The swimming season comes with the onset of autumn, so if you are sure that your pool is cleaned in good faith, you should not worry.
