Quick Take
As per a Facebook post, peeing in a swimming pool is dangerous for your heart and lungs. After fact checking, we found it to be half true.
The Claim
A Facebook user shared a post, “Urinating in a pool is dangerous for your heart? Urine and chlorine create dangerous chemicals when combined. One of those chemicals, cyanogen chloride is classified as a chemical warfare agent and can damage your heart and lungs.”
Fact Check
Is peeing in a swimming pool really bad for your heart?
No, not really. The claim that peeing in a swimming pool can harm your heart is not directly supported by the evidence provided. However, there are several factors to consider before providing a concrete answer to this question.
It is true that urine can combine with chlorine disinfectant in swimming pool water to produce potentially harmful chemicals. The urine and chlorine reaction produces cyanogen chloride and trichloramine. But, the concentration of urine and thereby the amount of harmful chemicals present is an important factor. Higher concentrations of urine may lead to the formation of more significant amounts of these substances.
A 2014 study suggests that urine and sweat contains uric acid, which can undergo a chemical reaction with chlorine to produce cyanogen chloride and trichloramine. These substances can be inhaled by swimmers, especially those who swim indoors. This can potentially lead to respiratory issues. Additionally, the amount of exposure to these chemicals matters too. Swimmers who spend extended periods in heavily contaminated pools may have a higher risk of inhaling these chemicals.
The environment of the swimming pool also plays a role. For example, indoor pools may have poor ventilation. This allows chemical concentrations to build up more easily and increases the risk of respiratory irritation for swimmers.
Studies have found associations between swimming in chlorinated pools and respiratory issues like asthma or lung irritation. But, there is no direct evidence linking these conditions to heart problems.
To conclude, urinating in swimming pools can lead to the formation of harmful chemicals that may affect respiratory health. Still, factors such as the concentration of urine, amount of exposure, and indoor versus outdoor pool environments also contribute to the overall risk. However, there is no direct evidence linking peeing in swimming pools and heart health issues.
We checked with Dr Darshan V. Joshi (Preventive Cardiologist), Pramukh Ayurveda Hospital, Palanpur for his expert opinion. He informed, “Swimming pool water is harmful only for the eyes and skin. For the case of swimming pool water mixed with urine, I would say that’s also harmful for the regular swimmers, like athletes, majorly in cases of indoor pools having poor ventilation. It does not harm the heart directly.”
Outdoor swimming pools are a safer alternative if you love swimming. Ask the pool manager to let you know what is the chlorine level and what is the status of water flow. Let them know they can also use alternatives which are safer.
What is the urine and chlorine reaction?
The urine and chlorine reaction in swimming pool water involves the chemical compound uric acid found in urine reacting with chlorine disinfectant. This reaction can produce two substances: cyanogen chloride and trichloramine.
Cyanogen chloride is a toxic gas that can be harmful when inhaled. It can lead to respiratory irritation and other health issues. Trichloramine, also known as nitrogen trichloride, is a volatile compound that contributes to the strong odour often associated with indoor swimming pools. Both of these substances can be inhaled by swimmers, especially in poorly ventilated indoor pool environments. This may cause respiratory discomfort or exacerbate existing respiratory conditions.
What are the consequences of inhaling cyanogen chloride and trichloramine?
Inhaling cyanogen chloride and trichloramine, compounds formed by the reaction of urine and chlorine in swimming pools, can lead to various health issues. These may include respiratory irritation such as coughing, wheezing, and throat discomfort. Prolonged exposure or high concentrations of these chemicals can exacerbate pre-existing respiratory conditions like asthma and bronchitis. Additionally, individuals with sensitive airways or allergies may experience more pronounced symptoms. Proper ventilation and maintaining appropriate chlorine levels in pools can help mitigate the risk of exposure to these harmful compounds.
Does this mean you should stop swimming?
Although swimming in chlorinated pools carries probable health risks, it’s important to consider the benefits of swimming. For most people, especially those who swim outdoors or only occasionally, the health advantages of swimming are greater than any risks from chlorine exposure. However, if you or a family member swims regularly indoors, it’s important to stay aware of symptoms like wheezing or chest tightness. Talk to a doctor if symptoms occur.
Swimming offers numerous health benefits. It can relieve arthritis and joint pain. It is also an excellent exercise during pregnancy, and offers valuable social and physical activity for children. Research even suggests that regular swimming can reduce the risk of mortality more effectively than running or walking. Therefore, swimming is an essential part of any exercise regimen.
Are there any alternative pool disinfection methods?
For those concerned about the use of chlorine in pool water, alternative disinfection methods exist. Some of the options include ozone, salt, silver, and copper. These methods can either reduce or completely replace chlorine, although they may come with a higher cost. Additionally, if you notice an excessively strong chemical smell at your community pool, it may indicate poor ventilation or improper pool maintenance. In such cases, ask the pool manager to check the cleaning system and improve air flow, especially for indoor pools. A clean and well-balanced pool should not emit a strong chemical odour detectable from a distance.
What are some of the healthy swimming tips?
Including healthy swimming habits into your routine can maximise enjoyment, and promote safety and hygiene. Some of the recommended swimming tips are:
- Make sure to use the restroom before you start, so as to avoid peeing in a swimming pool.
- Prior to swimming, always take a shower to wash away sweat, oils, and any lingering products on your skin. Thus, you can keep the pool cleaner for everyone.
- Apply sunscreen liberally and regularly to shield your skin from harmful UV rays. Opt for a broad-spectrum sunscreen with an SPF of 30 or higher. Remember to reapply every two hours, or more frequently if you’re swimming or sweating heavily.
- Stay hydrated by drinking water before, during, and after your swim to prevent dehydration. This becomes all the more important when spending time in the sun or heated pool environments.
- Take regular breaks from swimming to rest and rehydrate, especially on hot days or during intense workouts, to avoid exhaustion and overheating.
- Avoid swallowing pool water as it contains potentially harmful bacteria or chemicals. Encourage children to refrain from drinking pool water and remind them to keep their mouths closed while swimming.
- Practise good hygiene by washing your hands thoroughly with soap and water after using the restroom. Encourage children to do the same.
- Consider using swim diapers for infants and toddlers who are not yet toilet trained to prevent accidents and maintain pool water hygiene.
- Follow posted pool rules and guidelines, including diving restrictions, no running on pool decks, and proper use of flotation devices. This is to ensure a safe and enjoyable swimming experience for everyone.
- Be mindful of others sharing the pool space and practise common courtesy by avoiding splashing excessively. It is important to respect personal space, and take turns on slides or other pool features.
We fact checked another claim related to swimming pools spreading HIV infection. We also fact checked a claim which said synthetic drugs can cause heart attacks. Another fact check article refuted a misinformation which claimed solar eclipse can cause sickness.
