Asthma and Exercise

We all know that exercise is crucial to good health. Our doctors tell us so, we read articles in magazines and online, and new studies about the benefits of exercise are all over the news. For most of us, getting enough exercise is a matter of getting motivated and making the time for it. But for asthma sufferers, exercise can be a very scary concept.

Asthma attacks are no laughing matter. They cause great difficulty in breathing, and if they're untreated or treatment is not effective, a trip to the emergency room is necessary. Asthma is the cause of a huge number of missed days at work and school each year. So many asthma sufferers avoid exercise altogether for fear that it will trigger an attack.

Exercise-induced asthma is usually caused by breathing through the mouth during exercise. When we breathe through our noses, the air is warmed and moistened before it reaches the lungs. But when we breathe through our mouths, as we tend to do during exercise, the air that goes into the lungs is much colder and drier. This causes sensitive muscles in the airway to contract, constricting the airway. This can cause an asthma attack in chronic asthma sufferers, as well as some people who do not otherwise experience asthma symptoms.

There are also other factors that may cause exercise-induced asthma. Two of the things that often cause regular asthma symptoms, pollen and pollution in the air, can also contribute to exercise-induced asthma. And in some particularly sensitive people, just the increase in the amount of air inhaled and exhaled can trigger an attack.

Preventing Exercise-Induced Asthma

Exercise-induced asthma is no reason not to get the exercise your body needs. There are things you can do to prevent it, such as:

• Avoid exercising in cold weather. Work out indoors instead. If you must exercise outside when it's cold out, wear a scarf or bandanna over your mouth and nose to help warm the air you breathe.
• Take the time to do a 15-minute warm-up and a 15-minute cool-down each time you exercise. This will help the lungs adjust to the fluctuations in breathing.
• Avoid things that have triggered attacks in the past when exercising. If the pollen count is high or air quality is low, postpone your workout or keep it indoors.
• Talk to your doctor about medication for exercise-induced asthma. He may suggest using your regular inhaler 15 to 20 minutes before exercising. If you're particularly active, he might prescribe a long-acting asthma medication that will help prevent exercise-induced asthma for 12 hours.

A diagnosis of asthma does not mean you can never exercise safely. It just means that you'll need to take a few extra precautions. There's no reason that asthma should stand in the way of physical fitness.
