**Phoenix Pools: City Water Nuking Baby Biome?**
By Franklin Everett ShawThe chlorine smell hits you the moment you step out of the car. It’s a familiar scent, a promise of cool relief from the relentless Phoenix sun. But what exactly is in that water, and how is it affecting your body, especially your delicate microbiome? Let’s dive deep into the chemistry of Phoenix pool water and explore practical ways to protect yourself.
Phoenix municipal pools, like those across the nation, rely heavily on chlorine for disinfection. The goal is to kill harmful bacteria and viruses, preventing the spread of waterborne illnesses. The EPA sets guidelines for chlorine levels in public pools, typically ranging from 1 to 3 parts per million (ppm). However, the reality is more complex.
The chemical composition of Phoenix pool water is a cocktail of chlorine, chloramines (byproducts of chlorine reacting with organic matter like sweat and urine), pH adjusters, algaecides, and stabilizers. The specific levels fluctuate based on bather load, sunlight exposure, and the pool’s maintenance schedule.
Chlorine, while effective, isn’t without its drawbacks. It can disrupt the skin’s natural microbiome, leading to dryness, irritation, and even eczema flare-ups. Chloramines, in particular, are responsible for that strong “chlorine” smell and are a major cause of eye and respiratory irritation.
So, what can a concerned Phoenix resident do? The key is a proactive approach, focusing on pre- and post-swim routines.
Step 1: Pre-Swim Protection
Before you even dip a toe in the water, consider applying a barrier cream. Look for products containing dimethicone or petrolatum. These create a physical barrier, minimizing chlorine’s contact with your skin. A good option readily available at CVS or Walgreens in Phoenix is CeraVe Healing Ointment. Apply a thin layer to exposed skin, focusing on areas prone to dryness, like elbows and knees.
Next, consider a probiotic supplement. While the science is still evolving, some studies suggest that certain probiotics can help support a healthy gut microbiome, potentially mitigating the impact of chlorine exposure. Look for a probiotic containing Lactobacillus and Bifidobacterium strains, available at Sprouts Farmers Market or Whole Foods Market in the Phoenix area. Start taking it a few days before your swim and continue for a few days afterward.
Step 2: Post-Swim Recovery
The most crucial step is to shower immediately after swimming. Use a gentle, pH-balanced cleanser to remove chlorine and chloramines from your skin. Avoid harsh soaps that can further strip your skin’s natural oils. Cetaphil Gentle Skin Cleanser, widely available in Phoenix drugstores, is a good choice.
Follow up with a generous application of moisturizer. Look for products containing ceramides, hyaluronic acid, or shea butter to help replenish your skin’s moisture barrier. La Roche-Posay Lipikar Balm AP+ is an excellent option, available at many pharmacies in the Phoenix metro area.
Consider a post-swim probiotic rinse. Dissolve a probiotic capsule in a small amount of water and gently apply it to your skin after showering. This can help reintroduce beneficial bacteria to your skin’s microbiome.
Step 3: DIY Pool Water Testing
While municipal pools are regularly tested, you can also test the water yourself for added peace of mind. Pool supply stores like Leslie’s Pool Supplies in Phoenix sell inexpensive test kits that measure chlorine levels, pH, and alkalinity. Follow the instructions carefully and compare your results to EPA guidelines. If you consistently find high chlorine levels or imbalances, consider contacting the pool management.
Step 4: Exploring Alternative Swimming Options
Phoenix offers several alternatives to traditional chlorinated pools.
Natural Swimming Holes: While not as common as in other states, some natural swimming holes exist within a reasonable driving distance of Phoenix. Fossil Creek, about two hours north of Phoenix, offers a beautiful natural swimming experience. However, be aware that these areas may have limited facilities and potential risks associated with natural water sources. Always check for water quality advisories before swimming.
Private Pools with Alternative Sanitation: Some homeowners in Phoenix are opting for alternative pool sanitation methods, such as saltwater systems or UV sanitizers. Saltwater systems generate chlorine through electrolysis, resulting in lower chlorine levels and fewer chloramines. UV sanitizers use ultraviolet light to kill bacteria and viruses, reducing the need for chlorine. If you have friends or family with private pools, inquire about their sanitation methods.
Community Centers with Saltwater Pools: Some community centers in the Phoenix area are starting to offer saltwater pools. Check with your local YMCA or community center to see if they have this option.
Challenges and Pitfalls
One common mistake is neglecting to shower immediately after swimming. Chlorine and chloramines continue to react with your skin even after you leave the pool. Another pitfall is using harsh soaps that strip your skin’s natural oils, exacerbating dryness and irritation.
Another challenge is maintaining consistency with your pre- and post-swim routines. It’s easy to skip a step when you’re in a hurry, but consistency is key to protecting your skin and microbiome.
Finally, be aware that individual sensitivities to chlorine vary. Some people may experience no adverse effects, while others may be highly sensitive. If you experience persistent skin irritation or other health problems after swimming, consult a dermatologist or other healthcare professional.
By understanding the chemical composition of Phoenix pool water and implementing these practical strategies, you can enjoy swimming without compromising your health. Remember, a proactive approach is the best defense against the potential downsides of chlorine exposure. So, grab your swimsuit, your probiotic, and your barrier cream, and dive in with confidence!
