Asthma & Exercise

So you have asthma? Think you can’t exercise safely? Read on, my friend, and discover how you *can* do so safely and how your body will benefit from the exertion!

Asthma is a chronic lung disease that is marked by the following characteristics that are present during episodes of airflow obstruction:

Coughing
Wheezing
Shortness of breath
Chest tightness

It tends to occur in people who are genetically or environmentally presdisposed to the condition. Some of the triggers that might start or make an attack worse include:

Exposure to allergens (animal dander, pollen, mold)
Viral respiratory infections
Airway irritants (tobacco smoke, environmental pollutants)
Exercise
Exposure to things such as dust mites or cockroaches, especially in childhood

Medical treatments for asthma include:

Anti-inflammatory agents (inhaled and pill-formed steroids)
Broncodilators

If the patient can manage his/her symptoms, it’s possible to avoid any critical or emergency breathing treatments, however, for people in a higher-pollutant area, this might prove to be a difficult task.

How can you prevent an asthma attack?

Bathe pets weekly
Do not smoke or permit smoking in your home
Stay inside with air conditioning when mold or pollen counts are high
Wash your bedding & stuffed toys once per week in hot water
Wash your hands often
Get a flu shot
Wear a scarf over your mouth and nose in the winter
Be proactive about knowing your “triggers” and avoiding them

Now, with this information in place where does exercise fit in to your asthmatic life? According to Dr. Jack Becker, chief of allergy and asthma at St. Christopher’s in Philadelphia, you shouldn’t give up on sports or exercise at all. You just have to be smart about how you play, and take special precautions to avoid a flare-up.

Nearly all doctors agree that the best way to prevent an attack during exertion (exercise) is to keep the medication (inhaler) close at hand. You shouldn’t use the inhaler more than 3 times during a game or exercise session—at that point, it’s best just to back off and rest a while. Additionally, if you are up the previous night with coughing and wheezing, it’s probably best to go lightly on the exercise the next day.

For something such as Exercise Induced Asthma (EIA), symptoms are slightly different, in that they will appear after about 6-8 minutes of exertion, and are often worse in cold, dry air.

For those with EIA, certain activities are preferred over others:

Swimming: this sport has a warm, humid atmosphere, year-round availability, and upper-body toning.
Walking
Leisure biking
Free downhill skiing (wearing a scarf or surgical mask to help warm the air while inhaling)
Team sports that require a short burst of energy are better than those that require more continual activity. Thus, baseball, football, golfing, gymnastics, surfing, or wrestling are preferred over soccer, basketball, field hockey, or long-distance running.

Remember, this condition is not “all in your head,” it is a real, physiological medical condition that requires appropriate treatment. While your doctor can be your biggest ally in treating your asthma, YOU are the one who can most effectively prevent your symptoms. Be smart, take your medication, and be proactive. And don’t let asthma sideline your physical activity—it does a body good!

Does Anyone You Know Have Asthma?

At first reading, there isn't much extremely shocking in this report. But with a little research, in my opinion it becomes alarming.

This information comes from the Asthma Society of Canada:

"Doctors define asthma as a 'chronic inflammatory disease of the airways' . It is one of the most prevalent chronic conditions affecting Canadians. Asthma can be diagnosed at any age, but often starts in childhood. Its prevalence in Canada has been increasing over the last 20 years and it is estimated that currently over 3 million Canadians have asthma.

"The three strongest risk factors for developing asthma are family history, exposure in infancy to high levels of antigens such as house dust mites, and exposure to tobacco smoke and/or chemical irritants.

"We're all pretty familiar with allergic triggers of asthmatic symptoms, such as mould, animal dander, pollen, dust mites, etc., but perhaps less familiar with non-allergic triggers such as certain drugs, chemicals, fumes and odours, respiratory viral infections, certain weather conditions, strenuous physical exercise, tobacco smoke, and air pollution.

"Urbanization appears to be correlated with an increase in asthma. The nature of the risk is unclear because studies have not taken into account indoor allergens although these have been identified as significant risk factors.

"Experts are struggling to understand why prevalence rates world-wide are, on average, rising by 50% every decade."

Alarming? Yes. Why?

First of all, the report was updated in April of 2005, yet most of the footnoted references are from the mid to late 90's. So the report is about "Canadians" in general; children are still not identified as a unique segment of the population, their needs, habits and susceptibilities are not taken into special consideration, even though the studies all concur that asthma often starts in childhood.

Next, approximately 3 million Canadians have asthma. You have to put that into the context of how many Canadians there are, which in the year 2000 was about 31 million, with an annual growth rate of approximately 1%. So about 9.6% of all Canadians have asthma. Almost one out of 10. If one out of 10 Canadians were in a wheelchair, or wearing a cast, we would take notice. Alarming, since we treat it so casually. It's a chronic disease, which means lifelong constant management and medication.

The world's current (overall as well as natural) growth rate is about 1.3% per year, while prevalence rates of asthma world-wide are, on average, rising by 50% every decade. So asthma is occuring over 3 times more than can be attributed to population growth. These are rough figures, just to give us an idea of what we're looking at.

And this is only about asthma. It isn't about illness from chemical poisoning, or deaths from poisoning, or lung cancer, or...

So it's time to take steps to prevent asthma and other chronic environmental illnesses and diseases. At the very least, search for and buy the least toxic cleansers for household use. Get educated! Then, store all chemicals safely and securely away from children and pets.

Don't allow smoking in your home, and be aware of and avoid air pollution, both inside and out. Air out your home completely three times a day. Did you know that cigarette smoke contains about 4,000 chemical agents, including over 60 carcinogens? The U.S. Environmental Protection Agency (EPA), the National Institute of Environmental Health Science’s National Toxicology Program, and the World Health Organization’s International Agency for Research on Cancer (IARC) have all classified secondhand smoke as a known human carcinogen—a category reserved for agents for which there is sufficient scientific evidence that they cause cancer.

The U.S. EPA has estimated that exposure to secondhand smoke causes about 3,000 lung cancer deaths among nonsmokers and is responsible for up to 300,000 cases of lower respiratory tract infections in children up to 18 months of age in the United States each year. If you have to smoke, just dig your own grave, don't drag others with you!

So, become aware and clean up your home environment.
