Swimmers cool off quickly due to the cold swimming water. In combination with the penetrating swimming water, this weakens the resistance of the swimmers. They are therefore much more susceptible to germs in the water and in the air of the pool. Harmful microorganisms can therefore cause swimmers to become seriously ill.
Pathogens in swimming water
There are several pathogenic microorganisms that can be present in swimming water. These are, for example, bacteria, viruses and parasitic protozoa. People who already have a lower resistance, for example due to age or chronic diseases, are more susceptible to these harmful microorganisms. It is therefore very important to properly clean and disinfect swimming water.
