Debunking Myths: Can You Really Catch a Cold from a Swimming Pool?


When it comes to myths surrounding swimming pools, one that often comes up is the idea that you can catch a cold from swimming in them. Many people have expressed concerns and misconceptions about the transmission of the common cold in pools. In this article, we will delve into the facts to debunk this common myth and provide you with a clear understanding of the topic.

Understanding the Common Cold

Before we dive into the myth, let’s first understand what the common cold really is and how it is transmitted. The common cold is a viral infection that primarily affects the nose and throat. It is caused by different viruses, with Rhinovirus being the most common culprit. The primary method of transmission is through respiratory droplets expelled from infected individuals when they cough, sneeze, or even talk. These droplets can then be inhaled by others, leading to infection.

There are many misconceptions about the common cold, including the belief that cold weather or wet hair can directly cause the illness. In reality, it is the viruses themselves that cause the infection, and not the external temperature or moisture levels.

The Role of Chlorine in Swimming Pools

To understand whether you can catch a cold from a swimming pool, it’s important to recognize the role of chlorine in pool maintenance. Chlorine is a common chemical used in swimming pools to maintain water quality and kill harmful bacteria and viruses.

The primary purpose of chlorine is to disinfect the pool water by destroying or inactivating various microorganisms, including bacteria and viruses. When added to water, chlorine forms a disinfectant called hypochlorous acid, which is highly effective in killing these microorganisms by disrupting their cellular structure.

There is a misconception among some people that chlorine cannot kill all germs. While it is true that some viruses and bacteria may be more resistant than others, properly maintained swimming pools with appropriate chlorine levels can effectively kill the majority of microorganisms.

Can the Common Cold Virus Survive in a Swimming Pool?

Now let’s address the question at hand: can the common cold virus survive in a swimming pool? Extensive scientific studies have been conducted to evaluate the survival of the common cold virus in water, and the findings provide valuable insights.

Several factors influence the survival of the common cold virus in water, including pH levels, temperature, chlorine concentration, and the organic matter present. Research has shown that the virus can survive for a short time in water, especially in conditions where the chlorine concentration is low or the pH levels are not properly balanced.

However, in a properly maintained swimming pool with appropriate chlorine levels and pH balance, the common cold virus is inactivated and rendered unable to cause infection. The Center for Disease Control and Prevention (CDC) and the World Health Organization (WHO) both confirm that chlorine is effective in killing the common cold virus when used correctly.

Other Factors to Consider

While the impact of swimming pool water on the transmission of the common cold is minimal, it’s important to consider other factors that can contribute to the spread of the illness in swimming pools. One primary factor is personal hygiene. It is crucial for all swimmers to practice good hygiene, such as showering before entering the pool and avoiding the pool if they are already feeling unwell.

Contaminated surfaces and shared equipment, such as pool toys or diving boards, can also play a role in the transmission of the common cold. Proper cleaning and disinfection of these items is essential to prevent the spread of viruses.

Additionally, respiratory droplets expelled by infected individuals, even outside of the water, can play a role in spreading the common cold. Swimmers should be cautious and mindful of coughing or sneezing in the pool area.

Maintaining regular pool maintenance and conducting water quality testing are vital to ensure optimal hygiene and safety. Monitoring the pool’s chlorine levels, pH balance, and regular cleaning of filters and other equipment help reduce the risk of any potential infections.

Expert Opinions and Research

To further support our debunking of the myth, let’s turn to the opinions of pool industry experts and research conducted on the transmission of the common cold through swimming pools. Professionals in the field unanimously agree that the risk of catching a cold from a well-maintained pool is extremely low.

According to the National Swimming Pool Foundation, the risk of catching a cold from a properly maintained swimming pool is actually lower than from other common places, such as schools or offices. The collective opinion is that the combination of chlorine disinfection, proper filtration, and good personal hygiene significantly mitigates the risk.

Research studies conducted by various institutions have consistently shown that swimming pool water, when properly maintained, effectively inactivates the common cold virus. These studies provide further assurance that the risk of catching a cold from a swimming pool is minimal.


In conclusion, the myth that you can catch a cold from a swimming pool is just that – a myth. While it is technically possible for the common cold virus to survive for a short time in water, a properly maintained pool with appropriate chlorine levels and pH balance ensures the virus is inactivated and unable to cause infection.

It is essential to practice good personal hygiene, keep the pool clean, and follow recommended maintenance protocols. By doing so, you can enjoy the benefits of your swimming pool without worrying about catching a cold. Remember, swimming pools offer numerous health and recreational benefits, and with proper precautions, you can safely enjoy all that they have to offer.
