CDC Says Urine Can Cause Eye Irritation and Coughing for Swimmers

Chlorine by-product can irritate swimmers.

— -- It's probably not the chlorine.

As pools open across the country, swimmers may find they end up with red eyes or even skin irritation after a long dip in the water, but the cause may be different than you think.

“As the concentration of by-products in the water increases, they move into the surrounding air as well,” the CDC said on its website. “Breathing air loaded with irritants can cause a variety of symptoms depending on the concentration of irritants in the air and amount of time the air is breathed.”

Swimmers at indoor pools should be especially cautious since there can be a build-up of irritants in the recycled air.

Once the air is saturated, chloramines can build up in pool water too, meaning swimmers without goggles should be careful to keep their eyes shut underwater.

The CDC recommends people take a shower before getting in the pool, make sure their pool as adequate air flow and good water quality. They also had one key suggestion for swimmers: institute regular bathroom breaks on land so there are fewer breaks being taken by swimmers in the pool.
