What Is Exercise-Induced Asthma? How To Deal With It

Written by Charushila Biswas , MSc (Biotechnology), ISSA Certified Fitness Nutritionist

Staying physically active has many health benefits. But vigorous or prolonged exercise may obstruct airflow and trigger bronchoconstriction (EIB) or exercise-induced asthma. It commonly occurs in 40% to 90% of people with asthma. However, people (including kids) without asthma may also experience it (1).

That does not mean you cannot exercise. You can stay active and fit with the right treatment and preventive measures. This article discusses exercise-induced asthma – its causes, symptoms, treatment, safe exercises to do, and precautions to take. Read on!

What Is Exercise-Induced Asthma?

Asthma triggered due to prolonged or vigorous exercise is known as exercise-induced asthma or exercise-induced bronchoconstriction. It is characterized by air passage constriction, causing breathing issues. It is usually triggered after 5-10 minutes of vigorous activity or within 5-20 minutes of exercising. As a result, kids and adults may find it difficult to do certain activities and exercise (including high-intensity workouts) (1).

If you or your kid is showing signs of exercise intolerance and avoidance with breathing difficulty, below are a few reasons for it.

Causes Of Exercise-Induced Asthma

When we breathe through our nostrils, the nasal cavity warms and humidifies the air. However, during exercise, people may breathe through their mouths, inhaling dry and cold air. The air passage muscles react to this change in temperature and air humidity by constricting and narrowing the airway.

Pollen or other allergens in the air, inflammation, and viral infection may also trigger exercise-induced asthma (1). Here are the typical signs and symptoms of asthma caused due to exercise.

Symptoms Of Exercise-Induced Asthma

Watch out for the below symptoms of exercise-induced asthma:

  • Wheezing
  • Coughing
  • Shortness of breath
  • Tightness in chest
  • Sore throat
  • Reduced endurance
  • Unusual fatigue
  • Upset stomach

If you experience more than one symptom right after 5-10 minutes after exercise or during exercising, stop immediately. You may resume if you feel better. However, if it recurs, consult a doctor.

Thankfully, exercise-induced asthma is treatable. In the following section, we discuss the various treatments available for exercise-induced bronchoconstriction. Take a look.

Treatment For Exercise-Induced Asthma

Experiencing exercise-induced asthma does not mean you have to stop exercising. Your doctor will prescribe inhalers to dilate your airway, making it easier to breathe while exercising. Additionally, they may prescribe short-acting beta-2 agonists, widely used asthma medications. The doctor may prescribe corticosteroids if you have inflammation in the airway (2).

Use the inhaler 15-30 minutes before exercising to prevent an asthma attack. Take the prescribed medications regularly. If you have asthma and know that exercising may aggravate your condition, educate your family, friends, and exercise instructor to help you with the first aid if you need it. Scroll down to know what you or anyone who attends to you can do.

First Aid For Exercise-Induced Asthma

There are four steps in the exercise-induced asthma first aid (3):

  • Step 1: Make the person sit upright and try to calm and reassure to help them.
  • Step 2: Ask them to take four puffs from the inhaler.
  • Step 3: Wait for 4 minutes to see if the symptoms subside.
  • Step 4: Call an ambulance immediately if the symptoms don’t subside.

Asthma attacks are unpredictable. That is why taking precautions is crucial to prevent exercise-induced asthma symptoms. Here are a few tips.

Precautions To Prevent Exercise-Induced Asthma

  • Always warm-up for 10-15 minutes before exercising.
  • Use your inhaler about 15-30 minutes before exercising.
  • Cover your mouth and nose when exercising in cold and dry weather.
  • Avoid outdoor exercises during spring to avoid pollen allergies.
  • Exercise indoors to avoid environmental allergens.
  • Carry a short-acting inhaler for emergency purposes.
  • Avoid swimming in chlorinated swimming pools.
  • Breathe through your nose while exercising.
  • Avoid changing your exercise routine drastically.
  • Do cool-down stretches for 10-20 minutes after exercising.

Apart from taking preventive measures, you may also switch to low-risk exercises – like the ones listed below.

Safe Exercises You Can Do

  • Brisk Walking: This low-impact aerobic exercise gets the heart pumping and burns a good number of calories. Slow down or stop when you feel out of breath. You may do it on a treadmill or outdoors. It is a great way to keep in shape.
  • Dancing: Dancing is a fun way to burn calories and get your serotonin levels high. Dance forms like cha-cha, tango, and contemporary help you stay physically active and learn a new skill. Make sure you do not stand directly under an AC vent.
  • Cycling: Cycling is a great way to burn calories and keep your legs in shape. However, avoid dry and rocky trails. Cover your nose and mouth (if the air is too cold). Alternatively, you can buy an exercise bike and exercise while enjoying your favorite playlist!
  • Water Exercises: Choose a pool that has chlorine-free and lukewarm water. You may swim or do low-impact aquatic exercises to strengthen and tone your body.
  • Resistance Training: Resistance band training exercises improve muscle tone. The bands come in various thicknesses, and you can do full-body exercises and burn calories anywhere, anytime.
  • Strength Training: Strength training with dumbbells, barbells, kettlebells, and a Smith machine can help improve muscle tone and power. You may train at the gym or buy a few weights at home.
  • Sports: Playing a sport is a great way to burn calories, stay fit, improve coordination, and build great friendships. Badminton, tennis, cricket, squash, etc., are great for improving overall fitness. But you must avoid certain sports unless you have a team of coaches and medics to attend to you during the game. In the following section, we discuss which sports to avoid. Scroll down.

Which Sport Commonly Causes Asthma Symptoms?

You can play and exercise with asthma or exercise-induced asthma and even participate in the Olympics. However, if you are not training as an athlete and do not have the support that elite athletes have, it is best to avoid the following sports:

  • Marathon
  • Triathlon
  • Skiing
  • Ice hockey
  • Football

The Takeaway

Exercise-induced asthma is treatable if diagnosed early. Be mindful of the symptoms. If you are experiencing asthma symptoms for the first time during or after exercising, talk to a doctor to determine the triggers. They will prescribe medications and treatment methods accordingly. Take precautions, medications, and follow the doctor’s advice, and you will be able to exercise without any difficulties.
