Asthmatics make up 12 to 15 percent of the population, according to the American Council on Exercise (ACE). Asthma attacks may be brought on by allergies, a respiratory infection, tobacco smoke, pollutants in the air, stress, or even exercise. Many people who have asthma suffer from exercise-induced asthma, or EIA. Although asthma symptoms can flare during certain types of physical activity, asthma can be managed during exercise, and it's important for asthmatics to maintain a healthy exercise regimen.
Why Exercise
ACE states that as your tolerance for exercise is built up over time, it's less likely that you'll experience an exercise-induced attack. Exercise is important because it helps you sleep better, reduces stress, makes you more energetic, strengthens your breathing muscles, boosts your immune system, reduces your risk of developing other diseases and helps you maintain a healthy weight.
EIA Causes
When you exercise, you breathe faster because your body needs more oxygen. Air is warmed and humidified in the nose, but during exercise you usually breathe through your mouth, which causes the air to be drier and cooler. Deceases in air temperature and humidity can cause bronchial constrictions. Sports or exercises that expose you to cold air and can cause an asthma attack. An exercise like swimming is less likely to cause an attack, because it exposes you to warm and moist air. Exercising when there are pollutants and tobacco smoke in the air can also cause an attack.
Considerations
Before you begin an exercise program, have a thorough medical evaluation. Your doctor can advise you on physical activity and may prescribe medications that will help control your asthma during exercise. During exercise, begin by warming up, so your body is ready for more vigorous activity. Avoid exercising in cold or dry air, rest when necessary and don't push yourself. When you're finished, cool down slowly, since a cool down can help you avoid an attack following exercise.
Best Physical Activities
According to the Asthma and Allergy Foundation of America, there are certain activities that are better than others for people with EIA. Activities that involve short bursts of energy, or intermittent periods of activity, are usually the best. This includes activities like walking, volleyball, gymnastics and baseball. Swimming is a good activity, because it involves breathing warm and moist air. Distance running, soccer or basketball are more likely to cause symptoms because of they are intense and require vigorous activity.
