Swimming Pools and Itchy Skin: Causes, Treatment, and Prevention

Swimming in a pool can be a refreshing and fun experience, but for some people, it can also lead to itchy skin. This common issue can cause discomfort and frustration, but understanding the causes, treatments, and prevention strategies can help you enjoy your time in the water without any unwanted side effects. In this article, we’ll explore the reasons behind swimming pool-induced itchiness and offer tips to keep your skin healthy and irritation-free.

Causes of Itchy Skin from Swimming Pools

Several factors can contribute to itchy skin after swimming in a pool:

  1. Chlorine and other pool chemicals: Pools are treated with chlorine and other chemicals to kill bacteria and prevent the growth of harmful microorganisms. However, these chemicals can also strip away the natural oils from your skin, leading to dryness and itching.
  2. pH imbalance: An improperly balanced pool can cause skin irritation. A healthy pool should have a pH level between 7.2 and 7.6. If the pH level is too high or too low, it can disrupt your skin’s natural pH balance and cause itching.
  3. Over-chlorination: Excess chlorine in the pool can cause skin irritation, including redness, itchiness, and even rashes.
  4. Swimmer’s itch: Also known as cercarial dermatitis, swimmer’s itch is a rash caused by an allergic reaction to microscopic parasites that infest some pools. These parasites are typically found in freshwater sources, but they can occasionally be present in inadequately treated swimming pools.

Treating Itchy Skin from Swimming Pools

If you’re experiencing itchy skin after swimming, there are several remedies to alleviate the discomfort:

  1. Rinse off: After exiting the pool, shower with soap and warm water to remove any residual chlorine and chemicals from your skin.
  2. Moisturize: Apply a fragrance-free, hypoallergenic moisturizer to your skin immediately after showering to help replenish lost moisture and soothe irritation.
  3. Over-the-counter treatments: Anti-itch creams containing hydrocortisone or calamine lotion can help relieve itchiness and reduce inflammation. Follow the instructions on the product’s packaging and consult with a healthcare professional if you’re unsure about using a particular treatment.
  4. Cold compress: Applying a cold compress to the affected area can help reduce itchiness and inflammation.
  5. Avoid scratching: Scratching can worsen the irritation and even lead to infection. Try to resist the urge to scratch, and consider using an over-the-counter treatment to alleviate the itchiness.

Preventing Itchy Skin from Swimming Pools

To minimize the risk of itchy skin while swimming, follow these preventive measures:

  1. Test pool water: Regularly check your pool’s chemical levels and pH balance to ensure a safe and comfortable swimming environment.
  2. Shower before swimming: Rinsing off before entering the pool can help remove any substances on your skin that could react with pool chemicals and cause irritation.
  3. Apply a barrier cream: Applying a waterproof barrier cream or petroleum jelly to your skin before swimming can help protect it from the drying effects of chlorine and other pool chemicals.
  4. Wear appropriate swimwear: Choose swimwear made from materials that are less likely to irritate your skin, such as polyester or nylon. Avoid swimwear made from materials like spandex, which can cause friction and exacerbate itchiness.
  5. Stay hydrated: Drinking water before, during, and after swimming can help keep your skin hydrated and reduce the risk of itchiness.


Itchy skin from swimming pools is a common issue, but understanding the causes and implementing proper treatment and prevention strategies can help you enjoy the water without discomfort. Always pay attention to your skin’s reaction after swimming and take appropriate steps to maintain its health. Consult with a healthcare professional or dermatologist if you’re concerned about persistent or severe skin irritation, as they can provide expert advice and recommend appropriate treatments. By following these tips, you can ensure a comfortable and enjoyable swimming experience for yourself and others.
