Q: What are the health risks associated with swimming?
A: The swimming pool water is in direct contact with the human body, and the body's metabolites (especially urine and sweat) and cosmetics will enter the pool water, creating a good environment for the reproduction of microorganisms in the pool water. If the pool water is not regularly replaced and disinfected in a timely manner as required, swimmers are at risk of contracting pathogens.
Q: What are some diseases that are transmitted through pool water?
A: Eye diseases: including trachoma, acute conjunctivitis, etc. Ear diseases: including otitis media, etc. Infectious skin diseases: including tinea pedis, tinea corporis, pyocytes, etc. Intestinal infections: Swallowing pool water containing E. coli and dysentery bacilli while swimming may cause diarrhea, etc.
Q: How to disinfect swimming pool water and its health hazards to the human body
A: Due to the difference in the hygiene management status of the venue, the change in the number of swimmers, the temperature of the pool water and the water exchange rate, etc., the disinfectant in the swimming pool water will change. The content is low, and it is easy to breed microorganisms. If the content is high, it will irritate the human skin and mucous membrane and corrode the human skin and mucous membrane.
Q: So what are the precautions we can take?
A: Try to bring your own towels, slippers and other supplies, and do not mix them with others. Strictly abide by the management regulations of the swimming pool, shower and soak your feet before entering the water. Swimmers should wear swimming caps, waterproof glasses, nose plugs, and earplugs during swimming. Do not rub your eyes directly with your hands after the swimming goggles enter the water, and rinse your eyes and swimming goggles with clean water in time. Rinse your mouth as soon as possible and wash your skin and hair with clean water.
In the process of swimming, we must also consciously put an end to the following uncivilized behaviors: do not shower before entering the pool, do not wear swimming caps, do not soak feet, spitting in the pool, and relieve the pool. Protect our own physical health.
