Public swimming pool contains 60 liters of urine
On average, each public swimming pool contains 60 liters of urine, which is a good condition for bacteria to grow.
In the hot summer weather, many people want to go swimming to avoid the heat but wonder if the pool water is clean. Researchers from the University of Alberta (Canada) surveyed and measured 31 swimming pools, both in hotels and sports centers. The results showed that each public swimming pool contained an average of 60 liters of urine.

Researchers say it's hard to keep swimming pools clean. The survey also found that one in five swimmers pees in the pool at least once. Swimmers Rebecca Adlington, Ryan Lochte and Michael Phelps have also admitted to peeing in the pool.
Compared to the total amount of water in the pool, the proportion of urine is very small, only about 0.0009%, similar to a drop of oil in a 500 ml bottle of water. However, swimming pool water containing urine is a good environment for bacteria to grow, which is harmful to the health of swimmers.
To protect your health, after swimming, you need to thoroughly clean your skin, mouth, and eyes. In addition, you should not eat immediately after swimming, but wait about an hour to reduce the risk of intestinal diseases.
