The Centers for Disease Control and Prevention (CDC) recently revealed why some swimmers get red eyes after a few laps in the pool and it's not what you think it is.

For many years you may have assumed, like we all did, that it was the chlorine in a pool that made your eyes bloodshot after awhile.  Truth is, its the urine in the water!

Michael J. Beach, PhD, associate director of the CDC’s Healthy Water Program, recently told Women's Health Magazine that the chlorine in pools binds with the swimmers body fluids (sweat and urine) and forms chemical irritants, ultimately causing red eyes for many.

So if you're headed to the pool this weekend, here's a couple of tips to keep you safe while swimming in a giant, communal bath of everyone's body fluids.

1.  Shower and use the bathroom before going into the pool

2.  Wear goggles!  if you're not wearing goggles, avoid opening your eyes under water.

3. Shower when your done swimming and rinse all that stuff away from yourself.
