in air that is drier than what is already in the body. About 90 percent of people with asthma also
have EIB, but not everyone with EIB has asthma. Symptoms for EIB often appear within a few
minutes after an exercise has begun and may continue for up to 15 minutes after you finish. Symptoms consist of shortness of breath, decreased
endurance and tightness in the chest among others. Once believed to be caused by air temperature,
recent studies indicate that the dryness of the air is more likely the trigger. If you don’t have asthma, but often have shortness
of breath during exercise, it might be time to see a doctor to find out if you have exercise-induced
