is a disorder that causes breathing problems during or after exercise.
The exact cause of EIB is unknown. One theory is that rapid breathing during exercise causes the air tubes (airways) to dry out. When the airways dry out, they become irritated, which can cause the air tubes to tighten and get smaller (bronchoconstriction
). Small air tubes make breathing harder.
Another theory is that EIB is caused by bronchitis: injury
to the layer of cells that line the airways caused by high flows of air moving through those airways during exercise.
consult with doctor and A brief warm-up (break a sweat) for 5-10 minutes before exercise may also help prevent EIB. You should rest for 5 minutes after the warm-up.Breathe through your nose during l exercise. The nose warms and adds moisture to the air more than mouth-breathing.
