As we approach the Olympic Games in Beijing, China this week is time to take note if you find yourself “breathing heavy” during or after exercise.  This may a sign of more than just good aerobic activity.  Exercise-associated asthma can be the culprit; in many cases you may not realize you have this form of intermittent asthma.  Symptoms such as coughing or difficulty breathing during or shortly after exercise are commonly seen. 

In the past several Olympic Games up to one-fifth of athletes have a history of EIA (exercise induced asthma).  It certainly does not keep these elite athletes sidelined.  EIA may be triggered by “oversensitivity” to changing conditions including temperature, humidity as well as air quality, during the workout.  

Strategies in dealing with EIA

·         Hydrate with water before, during and after exercise

·         Warm up with a decent stretch and light exercise

·         Give yourself an adequate period for a “cool down” when done

·         Control your allergies and asthma triggers (especially on high pollen count days)

·         Check out the air quality index (pollution and ozone levels) before you exercise outdoors

·         Pre-treat with inhaled medication as advised by your doctor (after your diagnosis is confirmed) to prevent symptoms

As we are going through our summer rainy season in many areas of the country I thought it would be an appropriate time to discuss a little know asthma phenomenon.  After a rainstorm pollen grains can be washed away lowering pollen counts and giving some allergy sufferers temporary relief.  However, a number of pollen grains, in particular grass pollen levels, may actually increase as much as 50 fold! It is thought that in some cases, these higher amounts of allergy causing particles, when inhaled, may bring on an asthma attack.  This has been categorized as “thunderstorm associated asthma” and it is indeed a paradox. 

A recent study published in the journal Thorax looked at millions of ER visits during a decade in Atlanta.  The study found that following a thunderstorm there were many more individuals seeking ER care for worsening asthma.

Other theories have looked at air quality and pollution that may be affected by rain and thunderstorms.  The relationship between thunderstorms and an increase in the number of emergency room visits for asthma has been identified in many studies throughout the world; however most doctors and patients may not be aware of this phenomenon. 

So for the 20 million Americans with asthma according to the American Academy of Allergy, Asthma and Immunology, the next time there is a thunderstorm, make it an opportunity to pay close attention to your symptoms and stay one step ahead for proper and timely asthma treatment.   This underscores the importance of having an “asthma action plan” for optimal asthma prevention and management.
