You walk into a public pool and your nose is hit with a blast of sharp chlorine. You think, “Well, at least it’s clean.” But here’s the twist: that strong smell is actually a red flag.
Chlorine doesn’t have a strong odor on its own. That “pool smell” comes from chloramines, which form when chlorine mixes with sweat, urine, and other organic matter in the water.
The stronger the smell, the more likely it is that the pool is overloaded with contaminants—and may not be as clean as you think.
Common Health Risks in Public Pools
1. Recreational Water Illnesses (RWIs):
These include diarrhea-causing germs like Cryptosporidium, Giardia, and E. coli that can survive even in chlorinated water.
2. Swimmer’s Ear:
Prolonged exposure to water can cause infection in the outer ear canal, especially in kids.
3. Skin & Eye Irritation:
Over-chlorination (or poor chemical balance) can lead to red eyes, itchy skin, and rashes.
4. Respiratory Issues:
Chloramine buildup in indoor pools can trigger coughing, wheezing, and asthma-like symptoms.
How to Stay Safe at the Pool
Before You Swim:
- Use the “sniff test”—if it smells strongly of chlorine, ask when it was last cleaned.
- Look for clear water—you should be able to see the bottom of the pool.
- Check for posted inspection reports (required in many states).
While Swimming:
- Don’t swallow the water.
- Take kids for bathroom breaks every hour.
- Shower before and after using the pool.
Bonus Tip: If you’re swimming outdoors, wear waterproof sunscreen. Some chemical reactions between sunscreen and chlorine can cause skin irritation, so look for gentle, fragrance-free options.
Bottom Line
Public pools are a summer essential—but they’re not risk-free. That “clean” smell? It might mean the opposite. Take a few smart steps to protect your skin, your ears, and your stomach this swim season.
