Exercise Induced Asthma

What Is Exercise-Induced Asthma? Like it sounds, exercise-induced asthma is asthma that is triggered by vigorous or prolonged exercise or physical exertion. Most people with chronic asthma experience symptoms of asthma during exercise. However, there are many people without chronic asthma who develop symptoms only during exercise. Why Does Exercise Induce Asthma? During normal breathing, the air we take in is first warmed and moistened by the nasal passages. Because people tend to breathe through their mouths when they exercise, they are inhaling colder and drier air. In exercise-induced asthma, the muscle bands around the airways are sensitive to these changes in temperature and humidity and react by contracting, which narrows the airway. This results in symptoms of exercise-induced asthma, which include: Coughing with asthma Tightening of the chest Wheezing Unusual fatigue while exercising Shortness of breath when exercising The symptoms of exercise-induced asthma generally begin within 5 to 20 minutes after the start of exercise, or 5 to 10 minutes after brief exercise has stopped. If you are experiencing any of these symptoms with exercise, inform your doctor. If I Have Asthma, Should I Avoid Exercise? No. You shouldn’t avoid physical activity because of exercise-induced asthma. There are steps you can take for prevention of asthma symptoms that will allow you to maintain normal physical activity. In fact, many athletes — even Olympic athletes — compete with asthma. Can My Exercise-Induced Asthma Be Prevented? Yes. Asthma inhalers or bronchodilators used prior to exercise can control and prevent exercise-induced asthma symptoms. The preferred asthma medications are short-acting beta-2 agonists such as albuterol. Taken 10 minutes before exercise, these medications can prevent the airways from contracting and help control exercise-induced asthma. Another asthma treatment that may be useful when taken before exercise is inhaled cromolyn sodium, such as Intal or Tilade,15 to 20 minutes before exercise. Having good control of asthma in general will also help prevent exercise-induced symptoms. Medications that may be part of routine asthma management include inhaled corticosteroids such as Qvar or Pulmicort. An inhaled long-acting beta-2 agonist combined with a corticosteroid, such as Advair or Symbicort, may be added to the treatment regimen. In addition to taking medications, warming up prior to exercising and cooling down after exercise can help in asthma prevention. For those with allergies and asthma, exercise should be limited during high pollen days or when temperatures are extremely low and air pollution levels are high. Infections can cause asthma (colds, flu, sinusitis) and increase asthma symptoms, so it’s best to restrict your exercise when you’re sick.

You’re coughing during cardioReader's Digest Coughing and shortness of breath are the most common symptoms of exercise-induced asthma, or EIB (exercise-induced bronchoconstriction, or narrowing of the airways). But many people may not recognize that they’re coughing as a result of asthma.  You may feel these symptoms a few minutes after starting exercise, or it could take 20-30 minutes. “Especially if somebody’s running, they may not feel it right away, but as the demands increase and they’re working harder, that’s when it kicks in,” says allergist Neeta Ogden, MD, a spokesperson for the American College of Allergy, Asthma and Immunology. In extreme situations, you may be gasping for air. Here are more surprising asthma triggers. Your chest and throat feel tightReader's Digest Your chest may feel constricted, like you can’t take deep breaths or get enough air into your lungs. Your throat could also tighten. If this happens, stop exercising and catch your breath. “Your whole body is working so much harder to get oxygen that it wouldn’t be recommended to take a break and then start exercising again without your medication on board,” Dr. Ogden says. You might be ignoring these asthma symptoms. You live in a cold or dry environmentReader's Digest EIB occurs when you breathe in air that is drier and cooler than the rest of your body, which is what happens when you inhale through your mouth while exercising. This type of air is a main trigger that makes your airways narrow. If the climate you live in is particularly cold or dry, your lungs are definitely more at risk. Content continues below ad Exercise leaves you exhausted instead of energizedReader's Digest Feeling exhausted while you exercise should be a red flag for exercise-induced asthma. Dr. Ogden warns, “People may not recognize that they’re short of breath and demanding more air from their bodies. They may call that fatigue.” Fatigue can be completely independent of symptoms in your airways, but you rarely feel fatigue without also experiencing respiratory problems. These are great ways to beat fatigue naturally. It takes you a while to recover from a workoutReader's Digest If you have exercise-induced asthma, recovery times after exercise can range from 30 minutes to a full hour, depending on the severity of the condition. To compare, a study from the Baylor Asthma and Pulmonary Rehabilitation Center in Dallas found that young exercisers who don’t have any form of asthma can recover in 2-3 minutes. Ask your doctor about getting a short-acting inhaler to use 15 minutes before exercising. If this doesn’t help, you may have regular asthma and need daily medication. You blew that big competitionReader's Digest Off your game and don’t know why? EIB could be making you winded and affecting your athletic performance. The good news is, you can still play your favorite sports. Even Olympic athletes can compete with exercise-induced asthma. “It doesn’t have to ruin your life and your exercise,” Dr. Ogden says, “but until you get treatment, it can absolutely limit what you do and change your game.” Content continues below ad You’re feeling out of shape when you shouldn’tReader's Digest Even if you’re not a professional athlete, but are still healthy and active, exercise-induced asthma can make you feel sluggish. Dr. Ogden says it doesn’t have anything to do with your fitness level—anyone can develop the condition. “With the right treatment, you can still do any kind of exercise,” she says. “The reality is that it certainly has nothing to do with how physically fit you are.” You swim in a chlorinated poolReader's Digest Generally, swimming is a great sport for people with exercise-induced asthma, because it still requires cardio demand, but the humid environment makes bronchoconstriction less likely. However, too much exposure to chlorine can irritate your respiratory tract. A study from the University of Milan found that the immediate effects of chlorine chemicals include inflammation in the nose, and other key parts of the respiratory system. At the Sport Science Institute of South Africa, researchers saw that 60 percent of swimmers suffered airway constriction after exercising in a highly chlorinated pool, regardless of whether they had any form of asthma. You live in a high pollen areaReader's Digest Pollen and other respiratory irritants can cause bronchial constriction, closing your airways and leaving you with the unpleasant asthmatic symptoms that affect your work out. Having allergies in general puts you at risk, so be sure you know the triggers for your allergies. Working out in springtime—prime allergy season—can intensify asthma symptoms. Content continues below ad You struggle to run long distancesReader's Digest Used to going for 10-mile runs? That will change if you develop exercise-induced asthma. The deep breathing that running requires, plus the sheer distance, can decrease your endurance if your airways are constricted. “You’re not going to be able to run as long or as far,” Dr. Ogden says. “Your symptoms will kick in before the running’s over and you’ll find yourself struggling.” In that situation, meds or an inhaler can help you power through runs from a 5K to a marathon.

Exercise Induced Asthma

Background Exercise-induced asthma (EIA) is a condition of respiratory difficulty that is related to histamine release, triggered by aerobic exercise, and lasts several minutes (see Pathophysiology). Causes include medical conditions, environmental factors, and medications (see Etiology). Symptoms of EIA may resemble those of allergic asthma, or they may be much more vague and go unrecognized, resulting in probable underreporting of the disease (see Clinical Presentation). The optimal treatment for EIA is to prevent the onset of symptoms, and the basis of treatment is with preexercise short-acting β2 -agonist administration. Long-acting β2 -agonists and mast cell stabilizers, as well as antileukotriene drugs have also been shown to be effective (see Treatment and Management). With proper interventions, the prognosis is excellent for athletes with asthma. Most symptoms can be prevented, and performance should not be limited by EIA with proper treatment (see Prognosis). Exercise-induced urticaria, or exercise-induced anaphylaxis, is often presumed to be related to EIA, even though this condition is extremely rare and unrelated (see Diagnostic Considerations).
