Park City Pools: Chlorine, Skin, and the Altitude Lie

Ever feel like your skin is screaming after a swim in Park City? You’re not alone. Many residents and visitors blame the altitude for increased chlorine sensitivity in the town’s swimming pools. But the truth is more nuanced, and the solution lies in understanding the science and adopting a targeted skincare approach.

The myth that altitude directly exacerbates chlorine sensitivity is largely unfounded. Chlorine’s effects are primarily chemical, not altitude-dependent. The real culprit in Park City is the combination of chlorine and the already dry, high-altitude environment.

Park City’s elevation (around 7,000 feet) means lower humidity. This naturally drier air pulls moisture from your skin, weakening its protective barrier. Chlorine, a necessary evil for pool sanitation, further strips away natural oils, leading to dryness, irritation, and that dreaded itchy feeling.

So, how do you combat this double whammy? It’s all about proactive skincare, both before and after your swim.

First, pre-swim protection is crucial. Think of it as building a shield. Apply a generous layer of a barrier cream or ointment before you even dip a toe in the water. Look for products containing ingredients like petrolatum, dimethicone, or shea butter. These create a physical barrier, minimizing chlorine’s direct contact with your skin.

A great option readily available at Park City pharmacies like Walgreens or CVS is plain petroleum jelly (Vaseline). It’s inexpensive, effective, and creates a robust barrier. Another option, often found at sporting goods stores like Jans Mountain Outfitters, is a thick swimmer’s lotion containing dimethicone.

Next, consider the pool itself. Not all pools are created equal. Some Park City pools utilize different filtration systems that can impact chlorine levels. For example, the Park City Aquatic Center at Ecker Hill Middle School uses a traditional chlorine system. The chlorine levels are carefully monitored, but sensitive individuals may still experience irritation.

The Silver Mountain Sports Club & Spa, with locations in both Park City and Kimball Junction, uses a combination of chlorine and UV sanitation. UV light helps reduce the amount of chlorine needed, potentially lessening irritation for some swimmers. However, chlorine is still present.

The St. Regis Deer Valley pool, while luxurious, also relies on a chlorine-based system. It’s important to note that chlorine levels fluctuate based on bather load and usage.

Now, let’s talk post-swim recovery. This is where you undo the damage and replenish your skin’s moisture. The instant you get out of the pool, rinse off thoroughly with fresh water. Don’t just towel off and go. This removes residual chlorine that continues to irritate your skin.

Follow up immediately with a gentle, hydrating cleanser. Avoid harsh soaps that will further strip your skin. Look for cleansers labeled “fragrance-free” and “for sensitive skin.” Cetaphil Gentle Skin Cleanser, widely available in Park City drugstores, is a solid choice.

Finally, and most importantly, moisturize, moisturize, moisturize! Apply a thick, emollient moisturizer while your skin is still damp. This helps lock in moisture and repair your skin’s barrier. Again, look for products containing ingredients like hyaluronic acid, ceramides, or glycerin. These are humectants, meaning they draw moisture to the skin.

Consider layering your moisturizers. Start with a hydrating serum containing hyaluronic acid, followed by a thicker cream or ointment. This provides both immediate hydration and long-lasting protection.

A common mistake is using lotions that are too light. In Park City’s dry climate, you need something substantial. Don’t be afraid to use a body butter or even a facial moisturizer on your body if that’s what it takes to keep your skin hydrated.

Another pitfall is neglecting sun protection. Chlorine can make your skin more sensitive to the sun. Always apply a broad-spectrum sunscreen with an SPF of 30 or higher before heading outdoors, especially after swimming.

Here’s a step-by-step routine you can adapt:

1. Pre-Swim: Apply a thick layer of petroleum jelly or swimmer’s lotion to exposed skin.
2. During Swim: Limit your time in the pool if you’re particularly sensitive.
3. Post-Swim: Rinse thoroughly with fresh water immediately after exiting the pool.
4. Cleanse: Use a gentle, fragrance-free cleanser.
5. Hydrate: Apply a hyaluronic acid serum to damp skin.
6. Moisturize: Follow with a thick cream or ointment containing ceramides or glycerin.
7. Protect: Apply broad-spectrum sunscreen before going outside.

Remember, consistency is key. This isn’t a one-time fix; it’s a lifestyle adjustment. By understanding the science behind chlorine irritation and adopting a proactive skincare routine, you can enjoy Park City’s pools without sacrificing your skin’s health. Don’t let the myth of altitude-induced chlorine sensitivity keep you from taking a dip. Take control of your skincare and dive in!
