Asthmatics Outdoors
Breathing in that fresh, pollen-filled, country air .
. . and continuing up the hillside
By Tania Larson
Looking up the Central Texas hillside just a moment ago, it didn't look
so steep. The beautiful spring afternoon seemed perfect for a day of adventure
in the Great Outdoors. Mother Nature seemed to be smiling through crystal
blue skies and the brightly colored faces of wildflowers.
Now the flowers mock every struggled step and the whistling wind isn't
the sound of a gentle breeze rustling through the trees, but the sound
of tortured lungs trying to expel air through the swollen airways of an
asthma attack.
For the millions of Americans with asthma the obstacles of outdoor sports
can seem impossible as their bodies react adversely to the world around
them. Central Texas is known for its allergy-inducing pollens and those
pollens combined with the strain of exercise can cause an asthmatic's bronchioles
to constrict preventing their muscles from getting the oxygen they need.
Some attacks simply make the asthmatic feel mildly out of shape, while
others can leave one unable to walk or even talk.
Fortunately, even severe asthma can be just another challenge to overcome.
There are many things one can do to take control of asthma and take to
the hills with confidence.
The Basics of Asthma:
The first step to controlling asthma is of course diagnosing it. Symptoms
may start at any time in your life, and if you are new to an area there
may be allergens there you have never encountered before, exposing you
for the first time to asthma symptoms.
Only a doctor can diagnose asthma, but here are signs that you may need
to discuss the possibility of asthma with your doctor. Whether asthma is
the cause or not, it is important that you find the reason behind any of
these symptoms.
-
Wheezing. If you ever hear whistling from your lungs, whether inhaling
or exhaling there's a good chance you have asthma.
-
Shortness of breath. Feeling short of breath (even if you simply
feel slightly more out of shape than you should) can be a symptom of asthma.
You should see a doctor as soon as possible if you have a hard time getting
enough air.
-
A feeling of tightness in your chest. If your chest feels tight
it may be the constricting bronchial tubes of an asthma attack.
-
A persistent cough. Asthma can cause inflamed and or blocked airways
that lead to a persistent cough.
What is Asthma?
Asthma is a potentially deadly disease, where the flow of air through
the lungs is made difficult by obstruction in the lungs. The bronchi of
an asthmatic's lungs are called hyperactive because they react to triggers
that are tolerated by people without asthma. These triggers cause the muscles
surrounding the bronchial tubes to contract, narrowing the air passages.
The lining of the airways become inflamed and swollen making the passageways
even smaller. Just to make things more difficult, glands produce excess
mucus which further clog and block the already narrow passages so that
breathing, especially exhaling, can be extremely difficult. Air can become
trapped decreasing the oxygen available to the body and leaving the asthmatic
feeling tired and weak.
Managing Asthma:
Because asthma is a chronic condition many asthmatics simply get used
to the disease rather than control it. So, no matter how mild or severe
your asthma seems to you it is important that you work with your doctor
to make a plan for managing your asthma. Here are some things to consider:
-
Rescue inhalers relax the muscles that tighten around the airways,
and are used during an attack as well as for acute symptoms like coughing,
chest tightness, shortness of breath, and wheezing. For more severe episodes
your doctor may prescribe a short course of oral steroids.
-
Long-term medications like corticosteroids, cromolyn or nedocromil
are prescribed to reduce the underlying problem of airway inflammation
for those who need to use their rescue inhaler more than twice a week.
Jeanne Aultfather, a licensed vocational nurse
at the Allergy and Asthma Immunology Clinic of Georgetown, Texas says the
one thing that asthmatics can do to dramatically improve their control
over their asthma is to listen to the advice they're given and use their
long-term medication as it is prescribed. She says many asthmatics "tend
to use their medication only when they are in trouble. They should always
be taking it as prescribed rather than just when they feel they need it."
-
Reducing exposure to triggers like allergens can help alleviate
the long term symptoms of constantly irritated lungs.
-
Peak flow meters can be used to chart your expulsion capacity and
allow you to monitor the condition of your lungs so that you can adjust
your medication as needed.
-
An action plan for use during attacks should be developed with your
doctor and altered through regular check-ups as you assess its success.
The National Heart, Lung, and Blood Institute (NHLBI) has created treatment
guidelines for asthma. These guidelines establish some general goals of
asthma therapy including: "Preventing chronic asthma symptoms and asthma
attacks during the day and night." This means "no sleep disruption due
to asthma, no missed school or work because of asthma, and no or minimal
need for emergency care or hospitalizations." The guidelines also include,
"maintaining normal activity levels, including exercise and other activities,"
and "having normal or near-normal lung function." If you don't meet these
guidelines your asthma is probably controlling you and you should discuss
your problems with your doctor.
According to the guidelines your job is to:
-
Take your medicines as your doctor suggests
-
Watch for signs that your asthma is getting worse and act quickly to stop
the attack
-
Stay away from things that can bother your asthma
-
Ask your doctor about any concerns you have about your asthma and
-
See your doctor at least every 6 months.
Taking to the Hills:
There are two main problems asthmatics have with outdoor activities,
the allergens and the exercise.
-
Allergy-induced asthma can be dealt with by taking antihistamines to help
prevent allergens from provoking an attack. In some cases immunotherapy,
a.k.a. allergy shots, can be used for building tolerance to certain triggers.
-
Exercise-induced asthma that can be triggered during the harder breathing
of physical exertion. Aultfather recommends, "If you have problems and
tend to get a little tight, use two puffs of your rescue inhaler (albuterol,
ventolin, etc.) before exercise as a preventative." She also suggests avoiding
cardiovascular activities, "Walking is better than running because there
is not as much strain on the lungs."
Checklist of things to do before you hit the open air:
-
Take an antihistamine at least a half hour before so that it has time to
set in.
-
Make sure to use any long-term medication regularly the days before you
head out into the great outdoors in order to reduce inflammation and the
chances of an attack.
-
Take two preventative puffs of your rescue inhaler before you hit the trail
to prevent constricted airways.
-
Make sure you take your rescue inhaler with you for use along the way.
-
Make note of the nearest medical facility, and take your doctor's number
along just in case.
The American College of Allergy, Asthma & Immunology says, "By taking
preventive measures, asthmatics should be able to do any sport. Not all
sports, however, are equally tolerated." Like Aultfather the College says,
"In general, exercise and sports that involve prolonged periods of running
are more likely to provoke asthma attacks than nonaerobic ones." Many sources
suggest swimming because the air tends to be warm and humid and is less
stressful on the lungs. The College encouragingly says, "In most instances,
exercise induced asthma can be controlled to allow participation in any
sport. Many Olympic athletes, including several gold medal winners, have
had asthma."
So get out there and hit the hillside for your choice of activity. Just
take the necessary precautions first. |
