 Cleveland Clinic dermatologist Dr. Jennifer Lucas says that can lead to a skin rash known as irritant contact dermatitis. But there are some things you can do to prevent the effects, like get your hair and skin wet before you get in the pool. So that it doesn't absorb the pool water, but instead absorb that more fresh water. Be sure to rinse off as soon as you get out of the pool as well to get the chemicals off the body.
