You probably assumed that chlorine is the reason behind your red eyes when you swim in public pools. Unfortunately, this long believed cause is actually innocent. Well, not completely. According to the Centers for Disease Control (CDC), the real reason is chlorine binding with a type of waste and it’s none other than urine.

When chlorine and urine mix, they produce chloramine, which is an eye irritant. Aside from that, it is a derivative of ammonia, meaning you are exposing yourself to respiratory problems whenever you use public pools.

What is even more disturbing is that the chlorine smell you get from pools is not actually chlorine itself. The CDC explained that it is a mixture of pee, sweat, dirt, and even poop from people when they bind with chlorine. The chemical formed can cause the bloodshot eyes and can even make you cough and give you runny nose.Swiming Kid Pool

Next time you observe red eyes in the pool, you already know what to blame. If the reason behind your red eyes does not throw you off just yet, the germs in the pool are not easily killed because of chlorine. You can get diarrhea by simply swimming at these public pools.
