Gepubliceerd op 24 juli 2025 om 13:58


Is the swimming pool as hygienic as you think? As a parent, you naturally want your child to be safe and healthy, especially during swimming lessons. Swimming pools are fantastic places for fun and exercise, but they can also contain hidden hygiene risks. From invisible bacteria to water quality, there are several factors to consider. In this article, you'll learn how to minimise risks and what to look for when choosing a swim school for your child. This will ensure that swimming lessons are a safe and enjoyable experience!

The Hidden Risks in Swimming Pools

No matter how clean a swimming pool looks, bacteria and viruses can always be present [9]. Children are particularly susceptible because their immune systems are not yet fully developed [20, 39].

Common Pathogens

  • Bacteria: E. coli and Pseudomonas aeruginosa can cause skin irritations, ear infections and gastrointestinal problems [11, 22].
  • Viruses: Norovirus and Hepatitis A can lead to diarrhoea and other infections [11, 25].
  • Parasites: Cryptosporidium is resistant to chlorine and causes prolonged diarrhoea [11, 37].

How do germs get into the swimming pool?

Germs enter the pool through [9]:

  • Sweat
  • Urine
  • Saliva
  • Faeces
  • Dirt from outside

In addition, skin flakes and sunscreen residue can also pollute the water [11].

Hygiene in swimming pools: What can you do yourself?

Fortunately, there are several measures you can take to reduce the risk of infection [11, 20].

Before swimming lessons

  • Shower Required: Have your child shower before swimming to remove dirt and sweat [2, 14].
  • Toilet Visit: Make sure your child goes to the toilet before the lesson [12].
  • Swimwear: Dress your child in clean swimwear [23].

During swimming lessons

  • Do not swallow: Teach your child not to swallow pool water [8, 14].
  • Regular breaks: Take regular breaks to go to the toilet and drink [14].
  • Hygiene: Encourage your child not to pee or poop in the water [15].

After swimming lessons

  • Showering: Have your child shower again after swimming to rinse off chlorine and other chemicals [14].
  • Rinsing: Rinse the swimwear immediately [37].

Checklist for parents: How to choose a hygienic swimming school

The choice of a swimming school is important. Pay attention to the following points to guarantee a safe and hygienic environment for your child [41]:

  • Water Quality: Inquire about the procedures for water maintenance and the frequency of checks [6, 7, 24].
  • Cleaning: Observe the general cleanliness of the changing rooms, showers and the swimming pool itself [41].
  • Rules: Are there clear hygiene rules for all visitors? [2, 18, 32].
  • Staff: Are staff alert to hygiene and safety? [4, 41].
  • Certification: Does the swim school have a certification for safety and hygiene? [6].

Costs and safety

The cost of swimming lessons can vary, but it is important to remember that safety and hygiene should be a priority. Sometimes a slightly more expensive swim school can be a better investment if it offers a cleaner and safer environment. Compare swimming lessons and find a good deal that fits your budget.

Swimming lesson methods and hygiene

Different swimming lesson methods can also affect hygiene. With intensive methods, for example, it is extra important that there is sufficient time for sanitary stops and that water quality is closely monitored. Read more about lesson methods and discover which one suits your child best.

Swimming safety and certificates

Obtaining a swimming certificate is an important step in your child's swimming safety. In the Netherlands, the Swimming ABC is the norm. With an A diploma, children can manage reasonably well, but for real safety it is advisable to go for the B and C diploma. For more information, check out the knowledge base for parents.
