Health Hazards in Swimming Pools and How to Deal with Them

While swimming is a popular and enjoyable activity, it is crucial to be aware of potential hazards that may compromise your well-being. In this article, we will explore the "unknown" health risks associated with pool environments and provide you with valuable insights on how to effectively manage and mitigate these risks. With our expert guidance, you can take proactive measures to ensure a safe and enjoyable swimming experience for yourself and your loved ones. Dive in and discover the knowledge needed to keep pool-related health concerns at bay.



Eliminate Health-Threatening Substances: Discover the Power of Modern Water Treatment

Until recently, the challenge of eliminating health-threatening substances from water seemed insurmountable. However, thanks to the remarkable advancements in technology, we now have a solution. Introducing modern UVM medium pressure lamps that effectively eradicate harmful trichloramine, parasites, algae, and other germs, allowing you to enjoy water that rivals the quality found in Olympic swimming pools.

Let's delve deeper into the health risks associated with pools that rely on standard water treatment methods.

The Root of the Problem: Pollution

No matter how diligent you are in maintaining a clean pool, various forms of debris find their way in, be it from poolsides, hot tubs, or even natural bodies of water. While you may cover your pool diligently, the moment you jump in, a significant amount of substances that jeopardize water quality enter the pool alongside you.

You may think, "But we always shower thoroughly before entering the water, so this doesn't concern us." However, only part of the equation is right.

Despite your efforts to eliminate visible dirt under the shower, microparticles of skin, hair, sweat, sebaceous and mucous secretions, bacteria, viruses, fungi, yeast, and residues of cosmetic products and sunscreens are still released into the pool from your body. These substances not only degrade water quality but also pave the way for additional issues.

Trichloramine: The Unseen Threat

When chlorine reacts with impurities, it generates a cocktail of chemicals—several hundred, in fact. Paradoxically, the process of chlorinating the pool inadvertently creates serious problems. Among the compounds formed, trichloramine (bound chlorine) emerges as the most hazardous to human health.

Stay tuned as we delve deeper into the repercussions of these health risks and explore the innovative solutions that guarantee safer and healthier pool experiences for all.


Because trichloramine is not soluble in water, this harmful substance is continuously released from the water surface into the air directly under your nose, from where it easily enters your body.

Did you know that trichloramine, a harmful substance, continuously escapes from the water surface into the air? This insidious compound easily enters your body, posing a range of health risks:

  • Acute conjunctival irritation
  • Coughing and breathing difficulties
  • Irritation and disruption of the upper respiratory tract epithelium
  • Development of asthma and allergies
  • Allergic reactions in sensitive individuals
  • Skin irritation and dryness

That distinct "chlorine" smell near your pool? It's a telltale sign of trichloramine, which jeopardizes your well-being. Learn more about trichloramine in our comprehensive article.

Saltwater Pools: Dispelling the Myth

Even in saltwater pools, trichloramine can form. The chlorine necessary for its production is generated through the electrolysis of dissolved salt (NaCl). It's time to debunk the myth that trichloramine is absent in saltwater pools, which stems from a lack of chemical education.

Parasites: The Invisible Intruders

Don't be fooled by crystal clear water—parasites can still lurk within. While many assume parasites are exclusive to natural swimming pools, documented cases prove otherwise. Some parasites, such as Cryptosporidium parvum and Giardia lamblia, are resistant to conventional disinfection methods. Beware of the symptoms they can cause:

  • Severe diarrhea
  • Vomiting
  • Mild fever
  • Abdominal cramps
  • Headaches
  • Loss of appetite
  • Fatigue

While the illness may last up to two weeks for healthy individuals, it poses a potentially fatal risk for children and those with weakened immune systems.

Algae: A Green Catastrophe

Nothing spoils the joy of swimming like overgrown algae. Even with diligent pool cleaning, algae can rapidly degrade your water quality, turning it into unsightly green sludge.



While addressing the aesthetic concerns of pool owners, the real danger lies in the toxic substances released by overgrown algae into the surrounding environment. Cyanotoxins, produced by cyanobacteria found in algae, can lead to symptoms such as nausea, headaches, and allergic reactions. In extreme cases, these toxins have been known to cause damage to vital organs like the liver, kidneys, heart, lungs, and nervous system. Clearly, the impact of algae should never be underestimated.

However, there is a straightforward equation at play. Higher chlorine concentrations in the water result in reduced algae growth. But relying solely on high chlorine levels is not an ideal solution from a health perspective. To ensure water safety, it is crucial to choose an appropriate technology for pool water treatment.

Discover the Solution: Chlorine-Free Water Maintenance

Pool chemistry and traditional filtration systems alone often fall short in achieving perfectly clean and healthy water. That's why public swimming pools, wellness centers, and pool owners are turning to modern medium-pressure UVM (Ultraviolet Medium-Pressure) systems for water treatment.
