Exercise-Induced Asthma: Symptoms, Causes, and Treatment

Exercise-induced asthma happens when your airways tighten during physical activity, causing symptoms like coughing, wheezing, or shortness of breath. Taking preventive steps such as proper warm-ups, using inhalers, and following prescribed medications can help manage these episodes. For expert guidance and comprehensive care, consult Dr. Ahmed El-Rafei, who offers personalized assessment, diagnosis, and treatment to help you breathe easier and stay active with confidence.

What is Exercise-Induced Asthma?

Exercise-induced asthma (also called exercise-induced bronchoconstriction or sports-induced asthma) occurs when your airways narrow during physical activity, making it difficult to breathe. Common symptoms include coughing, wheezing, and shortness of breath, which can appear during or after exercise.

Symptoms may be more noticeable in cold, dry air or when pollen levels are high. With proper management, including warm-ups, inhalers, and medications, people with exercise-induced asthma can safely stay active.

Symptoms of Exercise-Induced Asthma

Exercise-induced asthma can cause a variety of symptoms, which may appear during or after physical activity. Common signs include:

  • Coughing – For some people, coughing may be the only symptom.
  • Wheezing – A whistling sound when breathing.
  • Shortness of breath – Feeling like it’s hard to get air in or out of your lungs.
  • Chest tightness or pain – A sense of pressure or discomfort in the chest.
  • Fatigue during exercise – Feeling unusually tired while being active.
  • Reduced athletic performance – Not being able to perform at your usual level.
  • Avoidance of activity – Often seen in children who may shy away from exercise.

These  symptoms often overlap with the signs and symptoms of asthma in children and adults, and their intensity may differ depending on the trigger and an individual’s response.

Symptoms can range from mild to severe and usually start a few minutes after beginning exercise or shortly after finishing. In most cases, they improve within about 30 minutes of rest. Sometimes, exercise-induced asthma symptoms may return up to 12 hours after exercising, even when you’re at rest. These are known as late-phase symptoms and may take up to a day to resolve.

Causes of Exercise-Induced Asthma

Exercise-induced asthma is often triggered by intense aerobic activity. Certain factors can make symptoms worse, including:

  • Cold, dry air – Breathing in cold air can irritate the airways.
  • High pollen levels – Allergens can worsen asthma symptoms.
  • Poor air quality – Pollution and smog can trigger airway constriction.
  • Recent respiratory illness – Recovering from a cold or infection can make symptoms more likely.
  • Exposure to irritants – Smoke, chemical fumes, or strong cleaning products can provoke symptoms.

With proper management, including warm-ups, inhalers, and avoiding triggers when possible, people with exercise-induced asthma can stay active safely.

Activities That Can Trigger Exercise-Induced Asthma

Any physical activity can potentially trigger exercise-induced asthma, but symptoms are more likely during sports or exercises that involve continuous exertion with little rest, especially in cold weather. Common triggers include:

  • Basketball
  • Ice hockey
  • Ice skating
  • Long-distance running
  • Skiing
  • Snowboarding
  • Soccer
  • Swimming, diving, or water polo in indoor, chlorinated pools (which can irritate the lungs)

With proper precautions, warm-ups, and the use of inhalers when needed, most people with exercise-induced asthma can safely participate in these activities.

How Exercise-Induced Asthma is Diagnosed

To diagnose exercise-induced asthma, Dr. Ahmed El-Rafei will review your symptoms, including when they occur and how long they last, ask about any family history of asthma or other airway conditions, and perform a thorough physical examination of your lungs.

Additional tests may include:

  • Pulmonary Function Tests: These assess how well your lungs are working, with spirometry being the most common test used to evaluate asthma.
  • Exercise Challenge Test: Also called a bronchoprovocation test, this involves exercising on a treadmill or stationary bike while breathing is measured before and after activity.
  • Chest X-Ray: Sometimes performed to rule out infections or other causes of symptoms.

With these evaluations, the most effective treatment plan can be determined to manage exercise-induced asthma, helping you stay active safely.

How is Exercise-Induced Asthma Treated?

Treatment for exercise-induced asthma focuses on preventing and relieving symptoms. Along with preventive steps—such as warming up before physical activity—medications may be prescribed to help manage symptoms. Some medications open your airways during symptoms, while others prevent symptoms from occurring.

Medications for Exercise-Induced Asthma

Medications are often delivered using an inhaler or nebulizer and can either prevent or relieve symptoms. Common inhaled treatments include:

  • Short-Acting Beta-Agonists (SABAs): SABAs are bronchodilators that relax the muscles in your airways. Also called rescue inhalers, they can relieve symptoms during an episode. Taking a SABA about 15 minutes before exercise can also help prevent symptoms.
  • Long-Acting Beta-Agonists (LABAs): LABAs are bronchodilators combined with corticosteroids and are not used alone. Inhaling LABAs 30 minutes to an hour before exercise can help prevent an episode.
  • Corticosteroids: These medications reduce swelling in the airways, increasing airflow. They may be prescribed for daily use to prevent symptoms.
  • Leukotriene Modifiers and Antihistamines: In some cases, these medications may also help reduce asthma symptoms.

With the right combination of preventive measures and medications, exercise-induced asthma can be effectively managed, allowing you to stay active safely.

FAQS

What Can I Expect if I Have Exercise-Induced Asthma?

Many people with exercise-induced asthma (EIA) manage the condition and lead active, healthy lifestyles. With proper planning and care, it is possible to exercise and enjoy a wide variety of sports and activities safely.

How Can Exercise-Induced Asthma Be Prevented?

Proper planning and preparation can help you avoid asthma episodes. Before physical activity, consider the following steps:

  • Warm up: Spend 6–10 minutes warming up before exercise. The routine should be tailored to your age, health, and type of activity. Ask your healthcare provider for guidance.
  • Check pollen and air quality: Avoid outdoor exercise if pollen levels are high or air quality is poor.
  • Cover your mouth and nose: Use a mask, scarf, or gaiter to protect airways from cold, dry air.
  • Manage asthma symptoms: Work with your provider to control symptoms and follow instructions for inhalers or medications.
  • Inform coaches and teachers: If a child has asthma, make sure adults supervising activities are aware and know how to respond. Adults should also monitor themselves for symptoms and know how to manage them.
  • Watch for symptoms: Monitor for signs of an EIA episode during or after exercise. Have a plan for responding quickly.
  • Choose suitable sports: Indoor or lower-intensity activities are less likely to trigger symptoms. Avoid endurance sports or outdoor activities in cold environments if prone to symptoms.

What sports are less likely to trigger exercise-induced asthma?

Sports Less Likely to Trigger Exercise-Induced Asthma

  • Baseball
  • Bowling
  • Fencing
  • Golf
  • Gymnastics
  • Pickleball
  • Sprints

How Do I Know if I Have Exercise-Induced Asthma?

Symptoms that start during or shortly after physical activity may indicate EIA. Because symptoms can resemble other conditions, a healthcare provider should make a proper diagnosis.

When Should I See a Healthcare Provider?

If you or your child experience EIA symptoms, schedule an appointment. Bring the following information:

  • The type of symptoms you experience
  • Activities during which symptoms occur (indoors/outdoors, same sport or different)
  • Duration of symptoms
  • What helps relieve symptoms, if anything
  • Demonstration of inhaler use if prescribed

What Questions Can I Ask My Healthcare Provider?
