## Disinfectants It would seem that their use is a no-brainer since they are designed to fight pathogens of all known diseases. Most often pool water is disinfected with chlorine, and it combines with organic substances in water (sweat, saliva, hair, etc.) to form chloramines. In large quantities, these can be harmful to health, as they cause [allergic reactions](https://ul.orna.me/KOge/librarydisease?id=21), irritation of the eyes and nose, cough, and skin dryness. These chemicals have even been linked to ===bronchitis and asthma for people who spend a lot of time in the pool. __How to protect yourself__ - Swim in pools that use modern combined water purification methods - Be sure to shower with gel or soap before and after swimming - Do not swim for longer than one hour - Use goggles and a swim cap, regardless of pool rules ## Skin diseases The main danger for [skin diseases](https://ul.orna.me/KOge/librarydisease?id=23) lies in the showers, on diving boards, and in locker rooms. Fungal skin lesions are especially common. __How to protect yourself__ - When walking around the pool, always wear rubber or plastic flip-flops - When showering, be especially careful to rinse hard-to-reach places where pool water could be trapped - Dry your body thoroughly with a towel, paying special attention to your feet - Moisturize your skin and use specific anti-fungal creams ## Inflammation of mucous membranes Chloramine irritation makes our mucous membranes at the swimming pool particularly vulnerable. Their defenses are weakened, which can lead to otitis media, rhinitis, and conjunctivitis. Insufficiently treated water can also lead to bacterial [infections](https://ul.orna.me/KOge/librarydisease?id=7). __How to protect yourself__ - Always wear goggles, which protect your eyes from chemicals in the water - If you are prone to otitis media, you should use special earplugs when swimming — you can purchase these at a drugstore or a sporting goods store ## Viral diseases Even if you think that your swimming pool observes all the preventive measures, there is always a chance you pick up a virus from a banal acute respiratory infection to [hepatitis](https://ul.orna.me/KOge/librarydisease?id=47) A and [HPV](https://ul.orna.me/KOge/librarybiomarker?id=3107). __How to protect yourself__ - Do not swallow water in the pool - Do not lean against the railing, benches, or floor with exposed skin - Wash your towel, swimsuit, cap, and washcloth thoroughly after each trip to the pool and disinfect your shoes - Avoid going to the pool if you have scratches and wounds on your body, if you have recently had an illness or are not feeling well, and during menstruation — at these times, the body is especially vulnerable Be aware that you cannot transmit [sexually transmitted disease](https://ul.orna.me/KOge/librarydisease?id=202) (STD) in the pool. Remember to avoid using the personal hygiene items of others at the pool — always bring your own.
