Dangers of Chlorine in Swimming Pools: What's Important to Know

Chlorine is the most common chemical substance used for disinfecting water in swimming pools. It effectively destroys bacteria, viruses, and other microorganisms, but when used improperly, it can harm human health and the environment.

Effects on the respiratory system

When chlorine comes into contact with organic substances (for example, sweat or urine), chlororganic compounds such as chloramines are formed. These substances evaporate and irritate the respiratory tract. This often manifests as:

throat irritation;

cough;

nasal congestion;

worsening of asthma in people with lung diseases.

Skin and eye irritation

Even with properly balanced chlorine levels, it can cause:

dry and itchy skin;

eye irritation and redness;

allergic reactions in sensitive people.

Risks for hair and nails

Chlorine damages keratin - the main protein that makes up hair and nails. As a result of frequent pool visits:

hair becomes brittle and dull;

nails can become layered and lose strength.

Long-term consequences

With prolonged exposure and inhalation of chlorine-containing vapors, the development of chronic diseases is possible:

bronchitis;

asthma;

deterioration of the general condition of the respiratory system.

Studies also link prolonged exposure to trihalomethanes (by-products of chlorination) with an increased risk of certain forms of cancer, especially among pool workers and professional swimmers.

Environmental harm

Discharge of chlorinated water into nature (rivers, soil) can lead to the death of aquatic organisms, disruption of balance in ecosystems, and contamination of groundwater.

How to reduce harm from chlorine in the pool

Shower before and after swimming - reduces water contamination and contact with chlorine.

Use of protective goggles and swimming cap.

Careful monitoring of chlorine levels and water pH.

Consideration of alternatives: ultraviolet purification, ozonation, salt systems.
