Exercise-induced asthma

Exercise-induced asthma is a form of asthma triggered by exercise. It is important to note that exercise is considered as a trigger that initiates asthma among those who engage in exercises.

What are the indications?

The indications of exercise-induced asthma strikingly resemble chronic asthma. In most cases, it starts after a few minutes of exercise or any strenuous activity that continues for around 10-15 minutes. The usual indications include the following:

  • Shortness of breath
  • Chest tightness
  • Wheezing or coughing
  • Unusual fatigue during physical activity

  • Diminished level of performance in usual activities


Exercise-induced asthma can be managed with treatment options to reduce or control the symptoms.

  • The symptoms of exercise-induced asthma can be reduced with the help of medications such as an inhaler or beta-agonist bronchodilator that contains terbutaline or salbutamol. The effects can last for up to 6 hours after an attack.
  • Inhalers or bronchodilators are also used as a preventive measure by using one before engaging in any strenuous activity.
  • A vital precautionary measure to prevent an episode of exercise-induced asthma is to use cromolyn sodium. It is inhaled 25 minutes after any physical activity.
  • Perform a 15-minute warmup to prevent the symptoms.
  • During cold weather, it is vital to keep the mouth and nose covered and warm the air. Another option is to go indoors to breathe in ventilated, humidified air.
