A swimming pool rash can develop within as little as a few hours after swimming and cause an unsightly rash accompanied by itching, swelling and redness. In some individuals the rash can develop with very little exposure and for some it's the result of repeated exposure over many weeks depending on the individual level of sensitivity. 

Chlorine Rash Symptoms

The culprit is usually the byproduct of chlorine after it comes in contact with sweat, urine and other biological substances often found in swimming pools. The chloramines can be found in the form of dichloramines, monochloramines or trichloramines that are all known irritants to skin and other mucous membranes including the ear, nose or throat and can lead to a chlorine allergy or sensitivity. 

One of the many benefits of a salt water pool is that chloramines aren't produced during the natural chlorination process. The absence of chloramines is the reason why salt water systems are considered the healthiest pools in the world. Many pool owners that have upgraded to salt water chlorination have experienced alleviated allergy symptoms and no red or irritated eyes or skin. If you would like more information about chlorine be sure to visit our what is chlorine page.
