How Exercise Triggers Asthma Attacks
When we're not exercising we tend to breathe through our nose, which warms and humidifies the air to make it like the air in our lungs. When we exercise we breath through our mouths, allowing colder and drier air into the lungs, potentially triggering an asthma attack. Swelling (brochiospasm) occurs, then mucus partially blocks airways. Using a face mask can be useful. Use the link to find some in the Resources section.
According to emedicine.com, unlike other forms of COPD, asthma is reversible but not curable. Using an inhaler as prescribed from your physician prior to exercising helps prevent attacks. Allowing yourself proper time to warm up before you go into heavy breathing during exercise also helps prevent attacks.
Lower Energy Output, Breath Through Nose
When you go out for trail runs, bike rides, snowshoe runs, or other endurance workout, start slow and let the breathing take place as much through the nose as possible. As you slowly bring your exertion levels higher, the transition for the lungs should be easier and help prevent attacks.
Many sufferers of exercise induced asthma are sensitive to air temperature, which in turn affects attacks. Using a facial or mouth cover to keep warm air in the lungs in cold weather is an effective means of preventing exercise induced asthma attacks.
Before heading out for those late fall trail runs, winter snowshoe sessions, or cross country ski workouts see your physician and ask about inhalers for EIA. Use it if prescribed, take care to warm up slowly, allowing the warm, moist air to enter your lungs gradually, and you can enjoy your back country workouts asthma free.
