Traffic pollution worsens asthma in children
A study carried out in Barcelona, and published in the journal Environmental Pollution - has found that the dry cold causes increase levels of toxic particles in the atmosphere, mainly from vehicle traffic and combustion.
Therefore, if environmental pollution by traffic late fall adds that within households there is also a higher concentration of mites and smoke because less ventilation, the consequence is that children with bronchi inflamed because of asthma , are more likely to suffer asthma attacks requiring hospital admission.
Another research conducted in ten European cities, and the results published The European Respiratory Journal revealed that children living within 75 meters from a road with heavy traffic have a 14% greater risk of developing asthma.
As Dr. Javier Torres, coordinator of the Working Group of the Spanish Respiratory Allergy Society of Clinical Immunology, Pediatric Allergy and Asthma (SEICAP), people with bronchial asthma have inflamed and narrowed, making it difficult to breath- and both the cold air as particles of sulfur dioxide or carbon dioxide-which irritate the air-way cause a worsening of symptoms like wheezing (wheezing), the coughing , or choking sensation .
In the case of having a respiratory allergies such as rhinitis (according to the SEICAP this allergy affects 9% of children under five years, and between 20 and 30% of adolescents aged 13 to 15 years), external pollutants also act as irritant, worsening the symptoms. Pediatricians allergists say that fall is the worst time of year for children with such disorders, and advised to avoid whenever possible that small traveling through areas with heavy traffic.
