Does Chlorine Cause Asthma in High-Performance Swimmers?

A study published by the Journal of Allergy and Clinical Immunology suggests that intense, long-term swimming training in indoor chlorinated swimming pools is associated with asthma-like airway changes. While strenuous training introduces airway pollutants, allergens, or irritants into the airways, the study showed that elite swimmers’ airways are particularly affected by the chlorine by-products used to disinfect swimming pools.

Can I Shower in or Use a Humidifier with Chloraminated Water?

The chemistry of chloramine is very complex, much more complex than the chemistry of simple chlorine. The US Environmental Protection Agency (EPA) finds no evidence of studies that investigate the use of disinfected water in humidifiers. However, the agency determined that using a humidifier or showering with chloraminated water poses little risk because monochloramine does not easily enter the air. See Question 21 in the linked article below for more information and other questions and answers ….

Children’s Exposures in the Swimming Pool Environment and their Potential Associations with New-onset Asthma

A respected group of clinicians, epidemiologists, exposure scientists, pool operations experts, and chemists convened at a workshop in Leuven, Belgium on August 21–23, 2007 to develop a research agenda to better understand children’s exposures in the swimming pool environment and their potential associations with new-onset asthma. Participants discussed relevant published studies, knowledge of asthma characterization and exposures at swimming pools, and epidemiologic study designs. Learn the results in this a groundbreaking study published in Environmental Health Perspectives, which set the path for future study in this area.

Swimmer's Lung

One medical practitioner has coined a new medical condition in a Letter to the Editor of the Canadian Medical Association Journal. Named “Swimmer’s Lung,” the condition establishes an association between coughs and the use of swimming pools that have been chlorinated.  Dr. Donal F. Conway believes that most pools are overchlorinated, sparking a chemical pulmonary irritation with resultant irritant cough that is evident with Swimmer’s Lung throughout the swimming season.
