Chlorine is usually used in the swimming pools. So can chlorine actually in swimming pools be harmful to your health? Let’s find out through the following article.
What is chlorine?
Chlorine is a chemical with very strong oxidizing and antiseptic effects so it is often used for disinfection and bleaching purposes. With such features, Chlorine is widely used in the fields of fisheries, textile, dyeing, water treatment and wastewater, swimming pools.
Currently, there are two types of chlorine chemicals that are free chlorine or hypochlorite. In the form of hypochlorite divided into 2 types: Hypochlorite sodium (NaOCl) in liquid form and Hypochlorite calcium [Ca (OCl) 2] in white powder form, with a stinging smell, when mixed with water with transparent color, taste. In order to disinfect and kill bacteria or inactivate microorganisms, people often use Hypochlorite calcium [Ca (OCl) 2] and apply it in aquatic production plants. And one more special thing is that, in any form of chlorine, whether pure or compound, when reacting with water, it produces a hypochlorite molecule that disinfects water with high treatment efficiency.
Once we know the properties of chlorine, we will explore the benefits and harms of chlorine.
Chlorine’s good sides:
– Swimming pools (especially outdoor pools) are considered one of the most polluted locations. These tanks are regularly exposed to the outside environment, easily infected by dirt, bacteria, spore algae in rainwater, and bird droppings. In addition to the pollution source, the swimming pool also includes microorganisms, the amount of oil excreted on the swimmer’s body such as sweat, cosmetics, sunscreen, urine, saliva, … Therefore, swimming pools must be chemically treated before use.
– An indispensable ingredient in swimming pool water often includes chlorine. This is the chemical used to disinfect and destroy the components that pollute the water.
Thanks to chlorine that kills pathogens and bacteria, swimming pools are a safe place to swim. And swimming pools that are not thoroughly disinfected will be the habitat for many types of bacteria such as Cryptosporidium – the main cause of diarrhea in humans or Chlamydia Trachomatis – the culprit of conjunctivitis in the eye.
Chlorine’s Bad sides
Although there are great benefits in pool cleaning, if the pool contains too much chlorine it can also harm our body. Typically, it affects the skin, eyes and also other dangerous harms such as: — In water, chlorine reacts with sweat, urine, skin cells and other biological materials to produce all kinds of by-products. Animal studies suggest that some of these chemicals are linked to asthma and bladder cancer.
– In two studies by scientists, 50 healthy adults were required to swim for 40 minutes. Experts then measure the doses of certain substances in the blood, urine, and breath of the person before and after swimming. Each measurement is determined by a biological tracer or markers that determine what’s going on in the body.
– Some other studies show that rescue workers at swimming pools and professional swimmers have a higher rate of asthma. Similarly, people who work in swimming pools are at higher risk of eye, nose, and throat disease than others. This time out of the biomarkers of respiratory problems, however, the new study found that the act of swimming led to an increase in the only sign of inflammation and the risk of allergies leading to asthma.
Therefore, if you go swimming regularly to get a healthier body, you also need to check the swimming pool where you swim to see if it is qualified for daily swimming or not. We will teach you some ways to know if a swimming pool is safe or not as follows:
– If the pool has a characteristic shocking chlorine odor that makes you feel uncomfortable when you smell it, the water in the pool is not being treated well.
– When the watercolor is clear, the bottom of the tank is clearly visible, medium green, not cloudy or there is a new object that is a standard swimming pool. If the swimming pool is unusually blue (other than the sky), pay attention.
– Human is also one of the factors that make swimming pools “toxic”. Therefore, if the number of people entering the pool is too crowded, the water filter in the pool will not be able to filter in time to remove toxins.
– You can use a swimming cap to protect your hair, avoid hair exposure to chlorine chemicals in the pool will dry hair breaks. In addition, swimming goggles also help you protect your eyes, avoid eye diseases.
– In addition, after leaving the pool, you can use a shower gel, shampoo with Ethylenediamine Acid (EDTA) to remove chlorine, and remember to apply body lotion to restore moisture.
As such, the swimming pool contains chlorine for the purpose of disinfecting the swimming pool, minimizing inflammation after swimming, so do not worry too much about swimming every day. As long as you know how to properly take care of your skin and hair, you will not worry about split ends or darkened skin. And remember to choose swimming pools that are not too crowded and have proper disinfection procedures to ensure safety!
