Your throat probably hurts after swimming in a chlorinated pool because of chloramines, not chlorine itself.
What are Chloramines?
Chloramines are chemical compounds that form when chlorine, used to disinfect pool water, mixes with organic matter brought into the pool by swimmers. This includes:
- Urine
- Sweat
- Feces
- Dead skin cells
These substances react with the chlorine to create chloramines.
How Chloramines Irritate Your Throat
Chloramines are what cause that distinctive "chlorine" smell in pools, and they're also responsible for many of the irritations swimmers experience, including:
- Throat irritation: Chloramines can irritate the mucous membranes in your throat.
- Eye irritation: Red, itchy eyes are a common symptom.
- Respiratory issues: Coughing and difficulty breathing can occur, especially in individuals with asthma.
- Skin irritation: Dry, itchy skin is another possible effect.
Why Not Chlorine Itself?
While chlorine is a disinfectant, it's generally the reaction byproducts (chloramines) that are more irritating than the chlorine itself at properly maintained levels. Pools that have a strong "chlorine" smell are actually likely to have high chloramine levels, indicating poor sanitation practices by swimmers.
How to Reduce Throat Irritation After Swimming
Here are some steps you can take to minimize throat irritation after swimming in a chlorinated pool:
- Shower before entering the pool: This helps remove sweat, urine, and other organic matter that contribute to chloramine formation.
- Avoid urinating or defecating in the pool: Obvious, but important!
- Shower after swimming: Rinse off any chloramines that may have accumulated on your skin and in your hair.
- Stay hydrated: Drinking plenty of water helps keep your mucous membranes moist and less susceptible to irritation.
- Swim in well-ventilated pools: Outdoor pools or pools with good ventilation systems help dissipate chloramines.
- Consider using a nose clip and goggles: These can help reduce exposure to chloramines in your nasal passages and eyes.
- Check pool chemical levels: Inquire with the pool management about the chlorine and pH levels, ensuring they are within recommended ranges.
By taking these precautions, you can help minimize your exposure to chloramines and reduce the likelihood of throat irritation after swimming.
