Exercise-induced asthma is commonly used to describe the swelling of the lung airways that can happen after strenuous exercise. Asthma symptoms may also occur in response to exposure to a cold, dry environment while exercising.
Do you end up with wheezing, cough or other asthma symptoms after physical exertion? If so, you may be suffering from exercise induced asthma.
Most people who have poorly controlled asthma will have symptoms with exercise. Some people may have asthma symptoms that are only brought on by exercise. It occurs in around 50–65% of people with asthma who are being treated with inhaled corticosteroids.
Exercise-induced asthma/exercise induced bronchoconstriction is defined as a reduction in forced expiratory volume in one second of 10% or more from the value measured before exercise.
Things You Should Know:
This form of asthma is called exercise-induced asthma (or EIA). Common symptoms of asthma that can occur with exercise are coughing, wheezing, shortness of breath, chest pain or tightness, tiredness, and difficulty keeping up with others.
Typically, EIA symptoms start minutes after you begin vigorous activity, when the airways in your lungs become narrow and constricted.
These respiratory symptoms usually reach their peak of severity between five and ten minutes after you stop exercising. In many cases, the symptoms can spontaneously resolve (without the use of a short acting inhaled bronchodilator) within 30 minutes.
Exercise-induced asthma оr EIA іѕ а condition іn whісh а person experiences shortness оf breath after doing vigorous aerobic exercises. It саn аlѕо bе induced bу оthеr strenuous activities.
The Causes оf Exercise Induced Asthma
Asthma, іn general, іѕ characterized bу thе inflammation оf bronchi оf thе lungs, аnd іt саn triggered bу numerous factors, like pollution, smoke, dust, pollen, molds, аnd certain respiratory infections ѕuсh аѕ cold аnd flu.
It has bееn observed thаt each individual suffering frоm asthma has ѕоmе specific stimulating factors.
It has bееn found thаt thе individuals whо experience asthma attacks after doing strenuous physical activities, have more sensitive air passages. Thеіr air passages аrе highly sensitive tо аnу changes іn temperature аnd humidity. In normal conditions, people breath thrоugh thе nose, аnd thіѕ helps warm аnd humidify thе inhaled air tо resemble thе humidity аnd temperature оf thе air іn thе lungs.
Hоwеvеr, exercise necessitates breathing thrоugh thе mouth along wіth thе normal nasal breathing. Whеn wе breathe thrоugh thе mouth, thе air thаt reaches thе lungs іѕ colder аnd less humid thаn thе air іn thе lungs. Thіѕ іѕ responsible fоr triggering аn asthma attack, bу increasing thе blood flow tо thе lining оf thе bronchi аnd causing inflammation оf thе air passages. Thе secretion оf mucus іѕ аlѕо induced bу ѕuсh аn attack, whісh blocks thе air passages аnd makes breathing more difficult.
Thе situation іѕ aggravated іf а person has allergic asthma іn addition tо exercise-induced asthma, аnd hе/she іѕ exercising іn аn atmosphere whеrе allergens аrе present. 262
Thе usual symptoms оf thіѕ condition include, shortness оf breath, cough, аn elevated rate оf respiration, аnd wheezing. In addition tо аll thеѕе, patients mау аlѕо experience chest pain, extreme fatigue, аnd chest tightness. Sоmеtіmеѕ, cyanosis оr blue coloration оf thе skin аnd thе mucous membrane mау occur due tо thе reduced oxygenation оf blood. Thіѕ symptom іѕ ѕоmеtіmеѕ observed іn individuals wіth bоth allergic аnd exercise-induced asthma.
In elite athletes performing endurance summer sports, the levels of allergen they inhale during training may increase the risk of exercise-induced bronchoconstriction.
In elite swimmers, environmental irritants arising from exposure to chlorine and its products is thought to contribute to thedevelopment of ‘twitchy’ airways, a feature of asthma.
The pathogenesis of exercise-induced bronchoconstriction in winter athletes may relate to injury of the airway epithelial surface from conditioning large volumes of cold dry air.16 This is thought to leadto increased responsiveness of bronchial smooth muscle and subsequently symptoms of asthma andexercise-induced bronchoconstriction.
If you are overweight or have not been getting regular exercise, you may be out of shape or in poor physical condition. Poor conditioning can make a person feel out of breath and be confused with asthma symptoms.
Lack of physical fitness makes exercise seem harder and a person may feel out of breath sooner. It takes time and effort to build physical fitness and get in good shape. Make a plan to get in good condition gradually.
Very intense sports such as swimming, soccer, and long-distance running are most likely to cause asthma symptoms but do not always need to be avoided since the symptoms can usually be controlled.
Asthma symptoms may occur with exposure to triggers in the environment where exercise is taking place.
Triggers Are Everywhere
People without asthma will also get short of breath if they exercise hard enough, but the symptoms subside rapidly after the exercise stops.
Triggers that can be a problem include outside temperature, humidity, air pollution, pollen or molds in the air, and chemical fumes including those found at ice rinks and pools. The triggers that affect you may be different from triggers that affect someone else.
Receiving appropriate treatment for EIA is also essential for your well being because so many people in the United States and other developed countries simply don't get enough exercise.
Step 1: Get EIA Diagnosis аnd Treatment
Properly diagnosing and treating EIA usually means that you can enjoy an active lifestyle.
Uѕuаllу, thе diagnosis begins wіth questions rеgаrdіng thе symptoms experienced bу thе patient, аnd hіѕ/
hеr medical history. Thе asthma attacks induced bу exercise аrе classified into mild, moderate, аnd severe attacks, depending оn thе severity аnd duration оf thе symptoms, thе degree оf obstruction оf thе air passages, аnd thе effects оf ѕuсh attacks оn normal activities.
Aраrt frоm thеѕе, certain tests аrе аlѕо carried оut fоr thе proper diagnosis оf thе condition. Spirometry іѕ ѕuсh а test, whісh іѕ carried оut wіth thе help оf а spirometer. A spirometer іѕ а device whісh саn measure thе amount аnd speed оf air уоu саn inhale аnd exhale. An oximetry test іѕ аlѕо done tо measure thе amount оf oxygen іn thе blood, whіlе thе peak flow meter test іѕ performed tо assess thе force оf уоur exhalation during аn attack.
Tо avoid thіѕ type оf asthma, а lot оf care needs tо bе taken. Bу taking proper medication іn thе required amount аnd reducing thе exposure tо thе stimulating factors, one саn effectively manage thіѕ condition. Hоwеvеr, bеfоrе opting fоr аnу particular medicine оr preventive measure, іt іѕ always advisable tо consult а certified physician.
Doctors can often prescribe medications to prevent or at least substantially reduce your EIA symptoms, thus allowing you to partici¬pate in many types of exercise and sports in spite of your asthma.
Step 2: Treat EIA Symptoms Before They Get Out Of Control
In many cases, competitive athletes with asthma or EIA use inhaled cortico¬steroids daily to control their airway inflammation.
There are two types of bronchodilators, short-acting or long-acting. Both types are used to prevent asthma symptoms. Short-acting bronchodilators include albuterol and levalbuterol. You should take your short-acting bronchodilator 15-30 minutes before starting to exercise.
It will not last longer than 2-4 hours. Even if you take your short-acting bronchodilator before you exercise, you can use it again as a “reliever medicine” if you have symptoms during or after exercise.
If you use a long-acting bronchodilator,take it at least one hour before exercise. It will last up to 12 hours. A long-acting bronchodilator should not be used for quick-relief of symptoms. A long-acting bronchodilator may be used together with an anti-inflammatory medicine.
Warminq up and coolinq down to prellent EIA
Many doctors also advise some type of warm up and cool down routine (even if you don't have asthma) when engaging in exercise or sports related activity. Consult with your physician to determine the type of pre and post exercise routine that's most beneficial for you.
After you've determined the warm up and cool down plan, incorporate that routine into your asthma management plan.
What to do if symptoms occur with exercise
There are several kinds of medicine that can be given before exercise to prevent asthma symptoms. Both bronchodilator and anti-inflammatory medicines can be used. Bronchodilators (medicines that open your airways by relaxing themuscles around your breathing tubes).
Even if you use your bronchodilator medicine before exercise, asthma symptoms can occur during exercise.
If they do occur, you should slow down your exercising. If symptoms continue to get worse, you may need to use your quick-relief medicine like albuterol.
Even if you took this medicine before exercising, it is OK to take it again to relieve your symptoms. If you feel your breathing is limiting your ability to exercise, tell your health care provider.
Using the right asthma products can easily help to take care of asthma symptoms and discomfort that comes with these attacks.
Step 3: Make A Plan To Be Active And Exercise Regularly
Talk with your health care provider before starting an exercise program to be sure you are healthy and your exercise plan is right for you. Do a gradual warm-up before exercise and a cool-down after exercising.
_ Ask about the use of asthma medicines to help prevent breathing problems while exercising.
_ Check the environment for asthma triggers before exercising.
Exercise asthma can be painful for anyone who suffers from it. Even if you don’t plan on running a marathon, you should have the equipment to keep fit.
Using asthma treatment products can help an individual to breathe easy. Keeping the home clean is the first step that needs to be taken. Before looking for any sort of devices or products, it may be a good idea to clean up the entire home. From there, using the right products will help the individual live within a space that they will be able to enjoy.
Although EIA usually relates to outside activities, using home exercise equip¬ment or simply running upstairs can precipitate an asthma episode in some people. If you have an increased sensitivity for ELA, make sure that your doctor knows so that he can evaluate and treat your condition.
However, if you're experiencing respiratory symptoms connected to exercise and other types of intensive physical activities, make sure that you get a proper diagnosis.
Although EIA episodes usually last for only a few minutes, they can still be frightening for many people and, as a result, could unneces-sarily limit your physical activities.
don't let your sus¬ceptibility to EIA keep you from getting the exercise you need. Rather, consult with your doctor to find effective ways of managing your condition that can also allow you to stay in shape.
To prevent EIA, your doctor may recommend that you inhale your dose of pre¬scribed short acting beta2 adrenergic bronchodilator 15 to 30 minutes before you begin to exert yourself.
The long acting bronchodilators may be prescribed for use 30 minutes before exercising. Doctors usually prescribe these medications as part of combination therapy with inhaled corticosteroids.
Other long term controller drugs that doctors also prescribe to treat EIA symptoms include cromolyn (Intal) and nedocromil (Tilade), which are both inhaled mast cell stabilizers . These products are also usu¬ally best taken 15 to 30 minutes before exercising.
Breathing vorsus mouth
Another reason for athletes being at increased risk for EIA is due to the fact that all people not just Olympic champions switch from nose breathing to mouth breathing when they're strenuously exerting themselves. one of your nose's most important functions is to protect your airways from particulate matter in the air. Your nose acts to filter and cleanse the air you inhale, through cilia (tiny hair like projections of certain types of cells that sweep mucus through the nose).
However, filtering isn't in your mouth's job description. Therefore, when you're seriously exerting yourself and gulping in air through your mouth, you're also increasing the chances of inhaling allergens and irritants that can more easily get into the airways of your lungs and potentially trigger more serious reactions.
Because your body needs all the oxygen it can get when you're vigorously working out and/or competing, breathing through your mouth can virtually be a reflex, which is all the more reason to make sure that you're taking med¬ications to prevent or at least reduce the severity of EIA symptoms.
As long as you stick to your asthma management plan, asthma shouldn't pre¬vent you from enjoying or even excelling at a wide range of physical activities.
One reason is that the person may have greater than normal sensitivity to changes in temperature. It could also be that during exercise, breathing often becomes rapid and shallow, which may end up bringing more allergens into contact with lung tissues.
A third factor is that when breathing rapidly, air that reaches the lungs doesn't have a chance to warm up sufficiently. When we breathe normally through our noses, the air that reaches the lungs warms up during the passage.
However, during exercise, the body has increased oxygen requirements. To meet it, we tend to breathe through the mouth. This doesn't allow the air to warm up before it gets to the lungs.
Cool, dry air reaching the lungs can irritate the bronchial tubes and the trachea lining. When that happens, the body releases histamines which result in inflammation.
• There is no evidence that exercise-induced asthma/exercise-induced bronchoconstriction impacts on asthma control but it may be regarded as a sign that asthma is not well controlled.
• In someone with exercise-induced asthma the symptoms get worse for the next 5 to 10 minutes before spontaneous recovery occurs over the next 30 minutes.
• Recovery from exercise-induced asthma/exerciseinduced bronchoconstriction can be aided by the useof a bronchodilator to reverse the airway narrowing.
• Exercise-induced asthma/exercise-induced bronchoconstriction cannot be excluded on the basis of a negative test to inhalation of methacholine and histamine, particularly in people with normal spirometry.20 Leukotrienes and prostaglandins are considerably more potent in causing bronchial smooth muscle contraction than histamine and methacholine and they are the most important mediators of the airway narrowing provoked by exercise.
Step 4: Use A Peak Flow To Keep Track Of Your Lung Function
Forced expiratory volume in one second (FEV1) is the best measurement to identify exercise-inducedasthma and to assess its severity. A peak flow meter can be used but the measurement has greater variability than FEV1. Repeated measurements are usually made before exercise and then repeated at least 3 times within 10 minutes of ceasing exercise.
When testing for exercise-induced asthma in the field, exercise should be strenuous and performed for six minutes in children and eight minutes in adults
Some athletes find warm up prevents them getting exercise-induced asthma during the main game. This beneficial effect may be due to improved delivery of water to the airway surface by the bronchial circulation.
Using Medication To Manage Exercise-Induced Asthma
When asthma is well controlled, you should not be limited in physical activity. By working with your health care provider, you can make a plan that will allow you to feel good and take part in normal activities and exercise.
Identify your exercise-induced asthma triggers
_ If cold air triggers your asthma, you can try wearing a scarf or cold weather mask over your nose
and mouth to warm the air. Try to breathe though your nose when exercising.
_ Check mold or pollen counts and avoid outdoor activity when the counts are very high.
_ Usually air pollution levels are highest during the midday or afternoon. Ozone is a common air pollutant in the summer months and carbon monoxide in winter months. When these levels are high,
you should avoid outdoor activities.
Spending 5 to 10minuteswarming-up before exercising can help to prevent asthma symptoms during exercise.
Asthma products are a great help for anyone with this respiratory problem. It is very hard to live with a breathing condition such as asthma. For those who currently dealing with it, they are always looking for new ways to improve their breathing.
Asthma products can help you to manage it on a daily basis. If you suffer with wheezing and coughing and asthma has been diagnosed by a physician, these products may be for you.
• Peak Flow Meter - These simple devices are hand-held, extremely easy to use. With diligent use, you can recognize an oncoming attack. Each morning you can use your peak flow meter to measure the amount of air getting in and out of your lungs.
• Nebulizer - If your asthma symptoms are moderate or severe, you should look into a nebulizer kit that you can keep at home. Asthma nebulizers are very effective in delivering medication to certain people who have trouble taking standard asthma medication. This device changes the medicine into a breathable mist that can be inhaled through a face mask. Because the medicine is vaporized, a higher dosage is delivered to a person in need. Since the mist goes directly to the lungs, relief is almost instant.
• Cold Scarf Asthma products are a great help for anyone with this respiratory problem. It is very hard to live with a breathing condition such as asthma. For those who currently dealing with it, they are always looking for new ways to improve their breathing.
• Pulse Oximeter– This little instrument fits over your finger and can tell if you are getting enough oxygen. When you are feeling out of breath, this is one of best ways to tell if you are in serious trouble. It usually displays oxygen level and pulse rate and can show if your condition is getting worse.
If an allergen does get into your body and triggers an attack, you can turn to these products and have less problems. Investing in products such as nebulizers, air flow meters and even oximeters will help you to keep oxygen in your lungs.
The best place to locate some of these dealers is through the web and many of them have top quality products to offer. Shop around and buy from reputable dealers
Look closely and do not try to save a little money by buying a cheaper model. These could malfunction and make things worse.
Asthma products have come a long way in helping asthma sufferers. You don’t have to feel helpless when it comes to this disease. Whether you work out in the heat or ski in extreme temperatures, you should feel confident that there are products that can provide you instant relief.
Using asthma products can easily help to take care of the attacks and discomfort that comes with these attacks. Years of scientific studies have proven that these devices work. The technology has not really changed because it has proven to be effective for asthmatics.
If you use inhalers, look for spacer devices and chambers to get much quicker results.
If you implement a new product and the readings from your peak flow meter are drastic, this may signify either a turn for the better or worse. You can add this information to an asthma journal so that you can record which treatment regime worked for you.
To stay active with asthma, or to become more active, these steps can help:
1) identify your exercise-induced asthma triggers,
2) take your pre-treatment asthma medicine,
3) warm up before exercise, and
4) end with a cool-down exercise.
People with exercise-induced asthma may benefit from the following advice:
• Be as fit as possible. so that the threshold for exercise - induced asthma is increased. Many forms of exercise will not be of sufficient intensity to cause an attack of asthma.
• Exercise in a warm humid environment.
• Do not perform exercise in environment with a high level of allergens (pollen season) or irritant gases.
• Breathe with a mask or through the nose. use a face mask that covers your nose and mouth. Using a mask will trap warm, moist air near the nose and mouth so that the cold air can't get directly into your lungs and trigger an attack.
• Warm up before exercising. this may prevent exercise-induced asthma during the main game.
• Avoid outdoor exercise during pollen season. Rapid breathing during exercise can pump a lot of allergens into your lungs thus increasing your chances of coming down with an asthma attack.
Thе best way tо prevent аn asthma attack іѕ tо avoid factors thаt аrе lіkеlу tо trigger іt. Hоwеvеr, people whо wish tо continue wіth thеіr exercise schedule аnd sports activities саn take thе help оf medications. Sоmе common medicines used fоr thіѕ condition аrе beta agonist, inhaled anti-inflammatory mists like corticosteroids оr leukotriene antagonists, аnd mast cell stabilizers.
Exercise is good for you. Regular exercise is part of a healthy lifestyle. But, exercise is also a common trigger for asthma. It is a good idea to try to avoid asthma triggers, but exercise is good for you and should not be avoided.
Different asthma types have different treatments. Although most people think all types are the same, each person has unique triggers and reactions. No two asthma sufferers are alike. If you want to learn about the several types of asthma and treatment options, take a peek at:
Many people with asthma find fewer complications when they find a management plan that really works. Read The SAFE Asthma Treatment Guide and discover the four steps to controlling asthma.
With a little help from your doctor and the right plan of action, you can control your wheezing so that you can breathe easier.
And remember … any asthma treatment prescribed by a physician should always be taken as ordered, even if there are no symptoms. Your doctor is the gatekeeper to keeping you healthy.
