**Phoenix Pools: Chlorine Fumes Inflaming Youth Lungs?**
By Franklin Everett ShawThe smell of chlorine hangs heavy in the air, a constant companion for competitive swimmers. But what if that smell, that ever-present marker of the pool, is also a sign of something more sinister brewing beneath the surface? For young athletes in Phoenix, Arizona, the potential link between competitive swimming and respiratory issues like asthma deserves a closer look.
Are Phoenix’s young swimmers at greater risk? Let’s dive in.
Arizona, like many states, has seen a rise in asthma rates among children. According to the CDC, in 2021, Arizona’s childhood asthma rate was around 7.8%, slightly above the national average. However, pinpointing whether competitive swimmers in Phoenix experience higher rates than their non-swimming peers, or even compared to swimmers in other states, requires a more nuanced investigation.
The culprit? Chlorine. While essential for disinfecting pool water, chlorine reacts with organic matter (sweat, skin, and urine – yes, urine) to form chloramines. These chloramines, not the chlorine itself, are responsible for that distinctive “pool smell” and are the primary irritants affecting swimmers’ respiratory systems.
Phoenix presents a unique case. The city’s intense summer heat necessitates indoor pools for year-round training. This extended exposure to chloramine fumes in enclosed spaces could exacerbate respiratory problems.
Let’s consider pool ventilation. Arizona’s pool codes, based on the International Building Code (IBC), address ventilation requirements for natatoriums. However, the effectiveness of these systems varies greatly depending on factors like age, maintenance, and the pool’s bather load. Older pools, particularly those in older parts of Phoenix like Central City or Maryvale, might have outdated or poorly maintained ventilation systems, leading to higher chloramine concentrations.
Contrast this with newer facilities, such as those found in the affluent Scottsdale area or the recently renovated pools in the Arcadia neighborhood. These facilities often boast state-of-the-art ventilation systems designed to minimize chloramine buildup.
So, what can be done? Here’s a practical, actionable plan for parents and coaches in Phoenix:
Know Your Pool’s Ventilation: Ask the pool management about their ventilation system. How often is it inspected and maintained? What is the air exchange rate? A well-ventilated pool should have a noticeable airflow. If the air feels stagnant and the chlorine smell is overpowering, that’s a red flag.
Pre- and Post-Swim Hygiene: Encourage swimmers to shower before entering the pool. This reduces the amount of organic matter that reacts with chlorine. After swimming, a thorough shower with soap is crucial to remove chloramines from the skin and hair.
Nasal Rinse: Chloramines irritate the nasal passages. Using a saline nasal rinse, like NeilMed Sinus Rinse (widely available at CVS and Walgreens across Phoenix), after swimming can help clear out irritants and reduce inflammation.
Swim Caps and Goggles: While not directly addressing respiratory issues, swim caps reduce the amount of hair exposed to chlorinated water, minimizing chloramine formation. Goggles protect the eyes from irritation.
Protective Swimwear: Consider investing in swimwear made from chlorine-resistant fabrics. These fabrics, often containing PBT (polybutylene terephthalate), last longer and may offer a slight barrier against chlorine absorption into the skin. Brands like Speedo and TYR offer chlorine-resistant options readily available at sporting goods stores like SwimOutlet or online retailers.
Air Purifiers at Home: Consider using a HEPA air purifier with an activated carbon filter in your child’s bedroom. This can help remove residual chloramines that may cling to clothing or hair after swimming. Look for models specifically designed for removing VOCs (volatile organic compounds), as chloramines fall into this category. Brands like Blueair and Honeywell offer suitable options at retailers like Home Depot and Lowe’s in Phoenix.
Monitor Air Quality: Consider investing in a personal air quality monitor to measure VOC levels in the pool area. While not a perfect solution, it can provide a general indication of air quality.
Dietary Considerations: Some studies suggest that a diet rich in antioxidants may help protect against the effects of chlorine exposure. Encourage your swimmer to consume plenty of fruits and vegetables.
Consult a Physician: If your child experiences persistent coughing, wheezing, or shortness of breath, consult a physician specializing in sports medicine or pulmonology. They can assess your child’s respiratory health and recommend appropriate treatment options.
Advocate for Change: Talk to your swim team’s coaches and pool management about implementing strategies to reduce chloramine exposure. Advocate for improved ventilation, regular water testing, and the use of alternative disinfection methods, such as UV systems, which can reduce the need for chlorine.
A common pitfall is assuming that a strong chlorine smell means the pool is clean. In reality, it often indicates high chloramine levels. Another mistake is neglecting post-swim hygiene. Swimmers often rush off to other activities without showering properly, prolonging their exposure to chloramines.
Let’s look at a hypothetical scenario: A young swimmer, Sarah, trains at an older pool in South Phoenix. She experiences frequent coughing and wheezing after practice. Her parents, initially dismissing it as a common cold, eventually realize the connection to the pool. They implement the strategies outlined above: Sarah starts showering immediately after practice, uses a nasal rinse, and her parents purchase a HEPA air purifier for her bedroom. Within a few weeks, Sarah’s respiratory symptoms significantly improve.
This isn’t just about individual actions. It’s about creating a culture of awareness and proactive prevention within the Phoenix swimming community. Coaches should educate swimmers about the risks of chloramine exposure and encourage them to take steps to protect their respiratory health. Pool management should prioritize ventilation and water quality monitoring.
While more research is needed to definitively establish a direct link between competitive swimming and asthma in Phoenix, the potential risks are clear. By taking proactive steps to mitigate chloramine exposure, parents, coaches, and pool management can help ensure that young swimmers in Phoenix can pursue their passion without compromising their respiratory health. It’s about breathing easier, both in and out of the pool.
