As the temperature climbs, many Americans will flock to the pool to find some relief from the heat. While the cool waters can be refreshing, they could also be contaminated with bacteria that can make you sick. Read on to learn about the three most common illnesses you can catch from spending a day at the pool.

Cryptosporidium (Crypto for Short)

Crypto, a chlorine-resistant parasite, is one of the most common culprits for post-pool day illness and causes diarrhea, stomach pain and nausea. Unfortunately, symptoms can last for up to two weeks.

To avoid getting sick, don’t swallow pool water or touch your face until you’ve showered with soap and hot water.

Pinkeye

Between the chemicals and other people’s bodily fluids in the pool, it shouldn’t be a surprise that you can catch pinkeye from swimming in a shared pool or hot tub.

To avoid getting this infection, wear well-fitted goggles every time you get into the water.

Hot Tub Rash

The warm water in hot tubs causes chlorine to break down quickly, making the chemical ineffective in killing the germ that causes an itchy skin infection that can lead to a bumpy, red rash.

To avoid getting this rash, shower immediately after going into the hot tub and be sure to wash your swimming suit before wearing it again.
