Share The swimming of babies is related to the risk of lung diseases

It is not the first time that we talk about a relationship between chlorine in swimming pools and respiratory diseases, however it is surprising that reference has been made to children under 2 years of age. According to a new study, children who start swimming before age 2 would be at risk of developing a frequent lung infection, bronchiolitis or asthma and respiratory allergies in the future.

The data, published in the "European Respiratory Journal", add to the evidence that exposure to chlorinated pool water affects children's respiratory health, especially if there is a family history of asthma or respiratory allergies, such as seasonal allergic rhinitis. .

Again, the danger of indoor swimming pools is stressed, where there is no air that can dissipate harmful substances. When chlorine is used to disinfect water, combined with sweat, saliva or urine, irritating substances are formed that, in time, can damage the airways.

Bronchiolitis is one of the susceptible diseases, an infection of the small airways of the lungs, usually caused by respiratory syncytial virus, which is common in babies. In the study, small swimmers with that infection were also at high risk of developing asthma or respiratory allergies kindergarten.

The study data

The study was carried out by a team of researchers in Belgium and is entitled "Infant swimming in chlorinated pools and the risks of bronchiolitis, asthma and allergy", "Infant swimming in pools treated with chlorine and the risks of bronchiolitis, asthma and allergy . "

Bernard's team evaluated 430 small children in Belgium and interviewed their parents to find out their children's medical history, if they swam and other factors. The authors found that 36% of children exposed to chlorinated outdoor pools or covered before 2 years of age had already had bronchiolitis.

In children who had only used indoor pools more than 20 hours before 2 years, the risk of suffering bronchiolitis was 3.5 times higher than in those who had never been in a pool with chlorine at that age. The risk in children swimming in indoor pools also increased. The risk is found in chloramine (resulting from the reaction of chlorine with organic elements derived from the skin and urine) in very high concentrations.

There were no significant differences in asthma and allergy rates between swimming and non-swimming infants. But by looking exclusively at the group that had bronchiolitis, the team saw that only swimmers had a higher risk of developing asthma and respiratory allergies.

Is swimming for babies discouraged?

The findings indicate that it is very likely that the irritation of the airways produced by chlorine derivatives increases the vulnerability of babies to bronchiolitis. Therefore, infection and chronic exposure to chlorine would interact to raise the child's risk of developing asthma and allergies in the future.

However, despite the fact that chlorine increases the risk of childhood allergies, scientists do not discourage swimming for babies, since it is a "pleasant" way for children to do physical activity.

But they should not forget that chlorine disinfectants and their derivatives are powerful irritants for the skin and airways, and therefore should not use excess chlorine in home pools and avoid public pools that do not control these aspects.

No doubt you have to regulate the application of chemicals in swimming pool water, especially those used by babies and children, because we can not enjoy the benefits of swimming if there are those implicit risks. We must be the first to demand it from those responsible for the pools.
