How to reduce risks related to swimming in chlorinated pools

Swimming is one of the best forms of exercise. However, it is always necessary to use proper precautions while swimming in a chlorinated pool to reduce the risks associated with exposure to chlorine. It is hard to believe that chlorine, once found to be an historic achievement and harmless, has now turned out to actually be poisonous.

There is much research going on in the area of substitute water treatments for the disinfection of pools. Public health officials and water system operators in the U.S. are working on plans to switch to ozone and UV disinfection,and advanced filtration systems that are not commonly used in public water systems. By decreasing the amount of chlorine added to pools and using just enough to to prevent the growth of pathogens. This, along with improved filtration and the use of non-chlorine disinfection will lead to the reduction of undesired organochlorines in the water. Making the water safer.


Step 1

Cleaning the pool along with testing and maintaining a safe chlorine level is part of essential pool maintenance and should be done all year round.

Step 2

Kits are available for the proper monitoring and maintenance of pools. The chlorine level in a pool should be kept between two and four parts per million and the pH kept between 7.2 and 7.8

Step 3

If pool smells of too high of chlorine do not use it. Postpone swimming until testing shows safe range.

Step 4

Avoid swallowing chlorinated water. If eyes are burning use goggles for swimming.

Step 5

Professional swimmers who spend a long time in the water should wear protective clothing.

Step 6

Shower and shampoo hair after swimming and rinse swimwear well.

Things Needed
• Pool cleaning supplies and chlorine monitoring kit
• Proper fitting goggles for long periods of time in chlorinated pool.
• Protective swimwear, such as chlorine resistant leggings made of Lycra.

Tips & Warnings
• Prolonged exposure to chlorinated water especially in indoor pools can be detrimental to the airways of swimmers and increase the risk of asthma and airway inflammation or respiratory allergies.
• Health effects related to prolonged exposure to chlorinated water are subtle such as outer and inner ear infections, illness related to immunity or even neurological damage.
