If swimming pools bring you out in hives, you may wonder what on earth's going on!

The itchy, bumpy, sore rash might look like a nasty virus or bacterial infection, but don't worry, it's not infectious!

Chlorine rash is simply irritant contact dermatitis, a reaction to the harsh chemicals used to treat the water of public swimming pools. It's not a virus, an infection or an allergic reaction.

Chlorine can trigger an inflammatory response, histamine release and subsequent itching, spots and raised areas of skin, but it should subside within a few days without any long-term harm or danger to anyone else.

Of course, chlorine is not the only possible culprit for a post-dip rash: check out Why Do I Get A Rash When I Go Swimming? for other possible causes, and always check it out with a doctor if you're worried.
