Exercise-induced asthma is unquestionably under diagnosed. Many who experience wheezing after exercise may brush it aside thinking it is a normal gasp for breath due to the aerobic activity. The primary cause of EIA remained a mystery for long. In several major studies it was found that children from dry, arid areas l had more problems with Exercise induced Asthma A than children living in the more humid coastal areas. In another study d asthmatics reported more EIA during winter than summer. Inhaled air is normally well humidified by the turbinate in the nasal passage and is warmed to body temperature when it reaches the lung. By testing people with EIA it was found that they have a defect in the mechanism that regulates warming and humidification of their inspired air during exercise. The allergic inflammatory cells known as the eosinophils, may be causing EIA. People with EIA may have an underlying inflammatory response that is signaled by the presence of eosinophils.

 

People with EIA should not avoid physical exercise. EIA is the easiest type of asthma to prevent and treat. In fact almost 10% Olympic athletes in US team had Exercise-induced asthma at one point of time (and even now). Such people should wear a face mask or scarf over their mouth and nose when exercising in cold, dry weather Such a mouth covering allows them to continually re breathe their own expired air, which is warmer and  better humidified. Warming up before main exercise reduces the severity of EIA. The second exercise within sixty minutes of the first often produces less broncho constriction.

 

The two main medicines in relieving and preventing EIA are cromolyn sodium and beta agonists. Cromolyn sodium given fifteen to thirty minutes before exercise blocks or minimizes EIA. A beta agonist taken ten to fifteen minutes before exercise prevents or reduces bronchospasm for up to two hours. When either drug alone is not effective, the two can be used in combination.
