Chlorine is a halogen, which is found in the environment only in compounds or as ions. As the chloride ion, it is abundant in nature and necessary to most forms of life. In its elemental form (Cl2 or “dichlorine”) under standard conditions, chlorine is a powerful oxidant and is used in bleaching and disinfectants. It’s often because of chlorine that there aren’t bacteria in your pool or drinking water. What do you do, then, if you think you’re allergic to chlorine?
From an allergic reaction to chlorine you could have difficulty breathing, including wheezing; highly irritated eyes, including swelling and itching; a red itchy rash, especially on your skin under your swim-suit; headaches; and nausea and vomiting.
If you’re experiencing an allergic reaction after using the pool, there are several treatments based on your symptoms. Some basic advice for skin irritation is to wash in soap and cold water. Then you can use Benedryll, Hydrocortizone cream or Calamine lotion to treat a skin rash.
If you have an actual allergy to chlorine then you’ll need to use a biguanide treatment for your pool instead of chlorine. Bromine treatments, as well, still use chlorine and therefore probably wouldn’t be an option.
A pre-school child is only safe in the pool with “touch supervision” – You should always be able to touch your child. Meaning, you’re in the pool with your child right next to them.
