Chlorine in Swimming Pools and the Link to Asthma

My husband has asthma and while he hasn’t struggled seriously with it, I am hoping our children will not get it.  So far, I think our daughter is in the clear but time will tell whether or not our son has it.  I’ve done many things to reduce their risk including keeping harmful cleaning products out of our house, using organic dairy products, keeping pets out of our house and using allergen free products on our beds

I’ve also kept them out of chlorinated swimming pools.  Don’t worry, our kids aren’t deprived of summer fun in the water.  There have been plenty of pools and sprinklers, but we’ve limited their swimming in chlorinated pools to the occasional pool party or vacation pool. 

Several studies have found a link between chlorine in swimming pools and asthma in children.:

  •  Science Daily reported that a study in Norway found that children with mothers who had asthma or allergies have an increased risk of wheezing if the child takes swimming lessons before 6 months.
  • A study in Belgium found that teenagers who spent more than 100 hours swimming in chlorinated pools were up to six times more at risk of having asthma than other teens.
  • The European Respiratory Journal reportedthat children who start swimming ( in indoor OR outdoor pools ) before the age of 2 may be at increased risk of bronchiolitis, and those who developed the infection were also at increased risk of developing asthma or respiratory allergies by kindergarten.

 All that being said, 20% of the U.S. Olympic swim team have asthma and they are obviously talented athletes, despite having asthma.

Alternatives to Chlorinated Pools

In the U.S., chlorine treated pools has been the norm for a long time but that is slowing changing.  Ozone and UV treated pools, common in Europe, are slowly making their way across the pond.  There are a couple salt water pools in our city, as well.  While many of these alternatives do use chlorine, the chlorine used is a lot lower.  The best way to find out how pools are treating their water is to call and ask!  The best way to avoid chlorine is to visit the great outdoors where you can find fresh water swimming opportunities at the beach, in the river or at the lake.

If you have your own pool, there are several purification systems that market themselves as chlorine-free including the Ecosmarte Pool, Carefree Clearwater, and EClear.

Now that my daughter is 3, she’s in swimming lessons, in a chlorinated pool.  With her age and interest in water, I think it’s important for her to have swimming skills for safety, exercise and lifelong enjoyment.  From current research findings, it sounds like she is also past the point of highest risk.  We will likely keep our son out of chlorinated pools until he is 2 or 3 and then enroll him in swimming lessons, too.  Hopefully by that time, we will have the opportunity to put him in a lessons in a pool treated with chlorine alternatives.  

Do you have chlorine-free pools in your area?  Are you concerned about chlorine in your pool’s water and the link to asthma?

Radon is the Leading Cause of Lung Cancer for Non-Smokers

January is National Radon Action Month, designated by the EPA, as radon is the leading cause of lung cancer for non-smokers and the second leading cause of lung cancer for smokers.  That’s approximately 20,000 deaths per year in the U.S. 

Radon is a naturally occurring, odorless, and colorless gas produced by the breakdown of uranium in soil, rock, and water. Because radon is a gas, it can enter homes through openings or cracks in the foundation. The radon gas itself decays into radioactive solids, called radon daughters. The radon daughters attach to dust particles in the air, and can be inhaled.

According to the EPA, over 8 million homes in the U.S. have dangerous levels of radon gas – could yours be one of them?   You cannot smell, taste or see radon so the EPA suggests that EVERY home regardless of age, location or type of construction be tested for radon gas. You can purchase a test inexpensively at a home improvement store or online for about $15.00.

I purchased our test in the fall and finally conducted it in early January.  It’s VERY simple, you basically hang it up in your house for 4-7 days while it collects the surrounding air particles and then mail it back in.  I got the test results within days.  The good news is that our home has a level of less than 0.3 pCi/L which is basically equivalent to the radon found in fresh air.

Purchase a radon test kit TODAY for your home and if you are planning to rent or purchase a new home, make sure you conduct a radon test as part of your inspection period.  If there IS radon, it’s not necessarily a deal breaker as there are ways to fix it.
