While it may seem like your child is allergic to chlorine, she’s technically not: The molecule is too small to stimulate the parts of her immune system that cause allergies. Similar to perfume, chlorine is a chemical irritant, and some kids are simply more sensitive to it than others -- resulting in sneezes with every exposure.
However, if your child suffers from seasonal allergies, high levels of chlorine in your neighborhood swimming pool can aggravate symptoms. In fact, a 2009 study published in the journal Pediatrics found that, among teens who are predisposed to develop allergic reactions, those who spent a lot of time in chlorinated pools were several times more likely to experience symptoms of allergic rhinitis and hay fever as those who didn’t swim.
But that doesn’t mean your daughter has to skip the pool this summer! When allergies are properly treated, kids should be able to participate in any activity. So make an appointment with your pediatrician or an allergist. (Check out AllergyAndAsthmaRelief.org for an allergist near you.)
Before your visit, keep an eye on your child’s symptoms to help your doctor determine the best course of action. Ask yourself:
- Does she sneeze only after swimming? It’s likely she’s having a non-allergic reaction to chlorine. Your doc will likely prescribe saline nose sprays, which are very effective at preventing and treating symptoms.
- Does she sneeze even when she hasn’t been near a pool? She’s likely suffering from allergies that may be aggravated by chlorine exposure. Your doctor can provide the medications to soothe her specific triggers -- including allergy shots, prescription antihistamines and prescription nose sprays -- so she’ll be able to jump right in at the next summer pool party.
