Parents are surprised when I tell them this… but red, burning eyes after swimming usually are NOT from ‘too much chlorine.'
The irritation actually comes from chemicals called chloramines.
And chloramines form when chlorine mixes with sweat, dirt… and urine in the pool.
So yes — peeing in the pool contributes to the eye irritation and strong ‘chlorine smell’ people notice at public pools.
Proper chlorine levels are important because chlorine helps kill germs and keeps pools safe. The problem happens when chlorine gets used up reacting with contaminants.
That’s why well-maintained pools actually smell LESS harsh, not more.
Here’s how to help protect your child’s eyes this summer:
Encourage bathroom breaks before and during swimming.
Have kids shower before getting in the pool when possible.
Use swim goggles.
And rinse eyes with fresh water afterward.
Mild redness after swimming is usually temporary irritation.
But if your child has significant pain, swelling, light sensitivity, thick drainage, or worsening redness, that’s worth getting checked out because it could be something more serious than simple pool irritation.
So next time someone blames chlorine alone for burning eyes… the pool chemistry story is a little more complicated than that.
