Summer is here! Safe Swimming for Kids: Why Pool Chemistry, Showers, and Skincare Matter

Swimming is one of the best ways for kids to stay active, build coordination, and have fun—especially in the warmer months. But as much as splashing around is good for the body and mind, it's essential to understand the role pool water chemistry plays in keeping children healthy. In particular, maintaining proper chlorine levels, rinsing off after a swim, and taking care of young skin can prevent irritation and long-term issues.

The Role of Pool Chemicals: A Delicate Balance

Pools need disinfectants—typically chlorine—to kill harmful bacteria and viruses. Chlorine is crucial for preventing infections like swimmer’s ear, pink eye, or gastrointestinal illnesses. However, when not properly balanced, chlorine can cause problems of its own.

Too much chlorine can lead to:

• Skin irritation and rashes

• Red, itchy eyes

• Dry or brittle hair

• Respiratory discomfort, especially in kids with asthma

  
  

Too little chlorine allows germs to thrive, increasing the risk of infection. The key is to strike the right balance: enough to keep the water clean, but not so much that it irritates sensitive skin and eyes.

If you own a pool or visit one frequently, it’s worth asking whether the water is regularly tested. Most public and private pools should check chemical levels at least once a day.

Why a Shower Before and After Matters

It might seem unnecessary to shower before jumping into a pool, but it helps more than you'd think. A quick rinse removes sweat, body oils, cosmetics, and traces of urine or feces that can react with chlorine to form chloramines—chemicals that can irritate the eyes and lungs and create that strong “chlorine smell.” That odor isn’t a sign of cleanliness; it’s actually a sign the pool is working hard to neutralize contaminants.

A post-swim shower is just as important. It helps wash off chlorine and any lingering pool chemicals that can continue irritating the skin and hair long after your child has towel-dried. Use a gentle cleanser and warm water, and don’t forget to rinse the scalp thoroughly.

Skincare After Swimming: Moisturizer and SPF

Chlorine strips the skin of its natural oils, which can leave it dry and itchy. Children, especially those with conditions like eczema, are particularly vulnerable. After showering, apply a fragrance-free moisturizer to lock in hydration and protect the skin barrier.

If your child is headed back outside after swimming, don’t forget sunscreen—even if it’s cloudy. Water can reflect UV rays, increasing the chance of sunburn. Look for a broad-spectrum SPF 30 or higher, ideally water-resistant, and reapply every two hours or immediately after drying off.

Final Thoughts

Swimming is a joy—and with a few extra steps, it can also be safe and skin-friendly. Make it a habit to check in on pool maintenance, encourage good hygiene habits, and protect your child's skin from harsh chemicals and UV rays. Their skin (and their health) will thank you for it.
