Asthma is one of the fasting growing conditions in childhood. The risk for development of the condition is increased by exposure to dust mites, family history, and exposure to second hand cigarette smoke. The World Health Organization estimates that somewhere between 100 and 150 million people have asthma worldwide, and many die each year from this condition.
Asthma is a progressive disorder of the respiratory system that results in a decreased ability to inhale air, primarily due to constriction of the airway with increased secretions. Children who have allergies are more susceptible to asthma. There are several different types of asthma, triggered by different mediators such as exercise, cold, or allergens.
A recent study from Belgium was published in the journal Occupational and Environmental Medicine. It found that asthma incidence may be linked to indoor swimming pool use. Indoor swimming pools and the air inside is a significant source of chlorine bi-products. The lead researchers believe that these bi-products may be the cause of asthma.
In the study rates of asthma in children were compared to the number of indoor swimming pools in more than 21 European countries. They found that for every one swimming pool, asthma rates increased by 2-3 percent. They do not state that indoor swimming pools are the only reason for a nearly 50 percent increase in asthma rates, but their influence definately cannot be negated.
The study authors call for more controlled studies relating asthma and indoor swimming pools, and in particular the exposure to chlorine bi-products. For parents who have children at risk for asthma, or who already have the disease, staying away from indoor chlorinated pools may be an effective form of reducing attacks.
Each year asthma attacks contribute to the death of more than 150,000 people worldwide. Preventative measures are so important, such as reducing exposure to allergens, proper cleaning and maintenance of bedding, as well as having needed medications handy.
