How to Prevent Recreational Water Illnesses This Summer

Spending time in pools, water parks, lakes, rivers, and beaches is one of the most popular ways to stay cool during the summer. While these activities offer fun and relaxation, they can also expose swimmers to certain health risks if the water is contaminated with harmful germs.

From stomach illnesses and skin rashes to swimmer's ear and other infections, recreational water illnesses can affect people of all ages. Understanding how these illnesses spread and following a few simple safety measures can help you and your family enjoy the water safely throughout the season.

What Are Recreational Water Illnesses?

Recreational water illnesses (RWIs) are infections that spread through contaminated water found in swimming pools, hot tubs, splash pads, lakes, rivers, and oceans. People can become sick by swallowing contaminated water, breathing in water droplets, or having direct contact with contaminated water.

Several germs are commonly associated with recreational water illnesses, including:

  • Cryptosporidium (Crypto)
  • Giardia
  • Norovirus
  • E. coli
  • Pseudomonas

Even well-maintained pools can occasionally harbor germs if proper hygiene and maintenance practices are not followed. This is why healthy swimming habits are important for everyone.

Fortunately, many recreational water illnesses can be prevented by following a few simple precautions.

Avoid Swallowing Pool or Recreational Water

Many people wonder whether they can get sick from swallowing pool water. The answer is yes. Even treated pool water may contain germs that can cause infection.

Children and adults alike should be encouraged to avoid swallowing water while swimming and young swimmers should be reminded to keep water out of their mouths whenever possible.

Practice Good Hygiene Before Swimming

Good hygiene helps reduce the spread of germs in shared water environments.

Before entering the pool or other recreational water areas:

  • Take a quick shower.
  • Wash your hands after using the restroom.
  • Ensure children take bathroom breaks as needed.

These simple habits can help minimize contamination and protect other swimmers.

Stay Out of the Water When Sick

If you are experiencing diarrhea or other symptoms of illness, it is best to avoid swimming until you have recovered.

Swimming while sick can introduce germs into the water and increase the risk of spreading illness to others.

Protect Your Ears and Skin

Taking care of your ears and skin can help prevent common swimming-related infections.

  • Dry your ears thoroughly after swimming
  • Change out of wet swimsuits promptly
  • Consider using ear protection if you are prone to swimmer's ear
  • Shower after swimming to remove potential irritants from your skin

Choose Safe Swimming Locations

Not all swimming areas carry the same level of risk. To reduce your chances of developing swimming pool illnesses or other waterborne infections:

  • Swim in properly maintained pools.
  • Check local health advisories before swimming in lakes, rivers, or beaches.
  • Avoid water that appears cloudy, dirty, or has posted warning notices.

These precautions can significantly lower your exposure to illnesses caused by contaminated water.

When to Seek Medical Care

While many recreational water illnesses improve on their own, some symptoms should not be ignored. Seek medical attention if you experience:

  • Severe diarrhea
  • Persistent vomiting
  • Signs of dehydration
  • Worsening ear pain
  • High fever
  • Symptoms that last several days

Prompt evaluation can help identify the cause of your illness and ensure you receive appropriate treatment. Urgent care centers can diagnose and treat many swimming-related infections and illnesses, helping you recover more quickly and return to your summer activities.

Make Every Swim a Safe One

Recreational water illnesses can interfere with summer fun, but many are preventable with simple precautions. Practicing good hygiene, avoiding swimming when sick, and choosing safe swimming locations can significantly reduce your risk of infection.

By staying informed and following healthy swimming habits, you can protect yourself and your family while enjoying swimming in pools, lakes, beaches, and other recreational water activities throughout the summer.
