Exercise-Induced Asthma

It is perfectly normal to breathe heavily when you run or perform some other form of vigorous exercise. However, if you begin to have trouble catching your breath, feel chest tightness, or begin to wheeze or cough when you exercise, you may be suffering from exercise-induced asthma.

About one person in eight experiences some form of exercise-induced asthma. Often, symptoms occur about 5 to 10 minutes into a hard workout, when your heart is into or above its aerobic range (80 percent of maximum). Symptoms are often at their worst when exercising in cold, dry air.

In the past, people suffering from asthma were instructed to avoid strenuous exercise. Today, individuals with asthma are encouraged to take part in physical activities. Being physically fit will not prevent symptoms of exercise-induced asthma from occurring. However, as you become more fit, you can exercise longer and harder before you experience symptoms. With adequate medical treatment and control, it is possible to participate in the activity of your choice with minimal or no asthma symptoms.

If you experience exercise-induced asthma, here are some strategies for relieving or preventing attacks:

• Breathe warm air. When exercising in a cold, dry climate, cover your nose and mouth with a scarf or other clothing. Breathe through your nose if possible. If your asthma is severe, you may want to work out at a gym or other indoor facility. Swimming and walking are good exercises for people with difficult-to-control asthma.
• Improve your fitness. As you become more fit, your body needs less air to meet its needs. As you take in less air, there is less strain on your airways, leading to fewer symptoms.
• Warm up. Warm-up exercises should consist of 20 minutes of light exercise or 5 to 7 30-second sprints with a 2 to 3 minute rest between. These exercises have been shown to lessen symptoms of exercise-induced asthma.
• Drink coffee. A cup of coffee or tea can help to dilate your airways before exercise.
• Take medication in anticipation of exercise. Work out a medication plan with your doctor to manage exercise-induced asthma symptoms. Adequate medical management can significantly reduce incidence of symptoms during exercise.
