It is estimated that 17 million people in America have asthma, with 5 million being under the age of 18. Asthma, which is Greek for to pant, is a chronic lung disease that triggers episodes of coughing, wheezing and shortness of breath which is caused by an inflammation of the lungs that result in the airways to narrow. It can take place at any age, and appears to have a genetic link. Although its symptoms are controllable, it is not thought to be curable.

Triggers for asthma can vary from one person to the other and may include allergens (dust, smoke, molds, pollens, and animal dander), chemical agents (cleaning products, perfumes, etc.), emotional stress and exercise. The best way to halt asthma attacks is to prevent them in the first place. Simple steps include controlling and managing house dust mites, animal related allergens, tobacco smoke, cockroach allergen, mold and other fungal spores and pollens, smoke from wood burning stoves, colds and viral respiratory infection, and physical activity or exercise induced asthma (EIA).

It was once thought that physical activity should be discouraged if you had asthma, but today this is not the case. With the appropriate precautions, exercise is not only considered safe, but it is frequently promoted as part of a sound respiratory therapeutic program. There are many ways to help avoid exercise induced asthma. If you have asthma, check with your doctor before you begin an exercise program and get a complete physical with a review of your current medicine therapy.

Some guidelines:

Warm up with 10 minutes or so of low intensity walking and gentle stretching and before your workout.

Avoid exercising in cold, dry air or in areas where air pollution or allergens are high. If you must exercise in a cold environment use a scarf or face mask to trap the warm moist air and prevent cold dry air from penetrating deep into your lungs.

After exercise, be sure to include a 10 to 15 minute cool down period.

Asthma attacks place significant stress on the body. Fatigue is common, making it even more difficult to breath. This is why a gradual progression with exercise is important. Developing cardiorespiratory fitness will make you feel less fatigued and will help lung function.

Different types of exercise may effect symptoms of asthma. For example, outdoor running is often worse than indoor running on a treadmill. To improve cardiorespiratory fitness, begin with 20 (or less) of low intensity aerobic activity 3 times per week, eventually building to five. Exercise in 10 minute intervals with a short rest in between. Use a cross training method applying different exercise modalities (i.e. treadmill, bike, rower). Swimming rarely causes EIA due to the warm moist air (however swimming in chlorinated pools may be a trigger for some).

Exercise intensity is also related to EIA and should be kept at a moderate level. You should be able to talk in short sentences throughout your workout.

Long duration exercise causes more exercise induced asthma then shorter bouts. Sports that promote stop and go activities such as tennis, volleyball & resistance training may cause less EIA in some individuals.

Keep your exercise up beat by making the most of your workouts, and avoid becoming bored or stressed, pick activities that you enjoy and can do.

If a medication is prescribed you can use it before exercise and monitor peak air flow with a peak flow meter. Your inhaler can be used during exercise also if symptoms arise. Talk to your doctor about how to use your inhaler with exercise. If notwithstanding your efforts, symptoms develop and persist, stop the activity and inform your doctor. Your doctor may recommend simple changes in medication that make the difference.

Drink plenty of fluids before, during and after exercise. Dehydration causes airways in the lungs to constrict, and makes breathing more difficult. Studies have shown that this is true even if the individual is not exercising. Thirst is a poor indicator of when to rehydrate, by the time you sense thirst your body is already lacking essential fluids.

Avoid alcohol and caffeinated beverages such as coffee, tea or sodas; these are diuretics, which dehydrate you even further.

Exercise-related breathing problems also occur in individuals who have not been diagnosed with asthma. People with allergies may experience many of the same symptoms, as exercise causes increased oxygen demand, breathing rate, and cooling and drying of the airways.

Although right now there is no cure for asthma, it can be managed with proper treatment and lifestyle management. Controlling symptoms may include using an inhaler or other medicine, as well as identifying and avoiding factors that may trigger an episode. Educating yourself as much as you can about asthma and your response to exercise gives you improved control and a greater chance of living an active life.

Asthma can strike at any age, half of all cases first occur in children under age 10; in this age group, asthma affects twice as many boys as girls. It is one of the leading causes of respiratory illness among children and young adults, however, this condition may progress a lifetime. It’s estimated 17-million Americans suffer from asthma.

Asthma is a reversible lung disease characterized by obstruction or narrowing of the airways. It may resolve spontaneously or with treatment. Its symptoms range from mild wheezing and shortness of breathe (dyspnea) to life-threatening respiratory failure. Symptoms may persist between acute episodes.

People with asthma do not have a problem inhaling, but rather, a problem exhaling. Airways open up during inhalation with the lowering of the diaphragm as the ribs move out making the lungs bigger allowing air to move around any obstruction. However, when the person exhales, as the rib cage relaxes, the diaphragm slides up preventing the air from getting around the obstruction.

TYPES AND CAUSES

Extrinsic asthma results from sensitivity to specific external allergens. In cases in which the allergen isn’t obvious, it’s referred to as intrinsic asthma.

Extrinsic asthma usually begins in childhood and is accompanied by other manifestations of atopy — A hereditary disorder marked by the tendency to develop immediate allergic reactions to substances such as pollen, food, dander, insect venoms, house dust or mold, kapok or feather pillows, food additives containing sulfites, or similar allergic conditions. In intrinsic asthma, no external allergen can be identified. Most cases are preceded by a severe respiratory infection. Irritants, emotional stress, fatigue, exposure to noxious fumes, changes in temperature, and changes in humidity, may aggravate intrinsic asthma attacks. In many asthmatics, intrinsic and extrinsic asthma coexist.

Several drugs and chemicals may provoke an asthma attack. Examples of these substances include aspirin, various nonsteroidal anti-inflammatory drugs, and yellow food dye (tartrazine). Exercise may also provoke an asthma attack. In exercise-induced asthma, bronchospasm may follow heat and moisture loss in the upper airways.

An asthma attack may begin dramatically, with simultaneous onset of many severe symptoms, or insidiously, with gradually increasing respiratory distress. It typically includes the following signs or symptoms or some conbination of them:

- progressively worsening shortness of breath – cough – wheezing – chest tightness.

During an acute attack, the cough sounds tight and dry. As the attack subsides, thick mucus is produced (except in young children, who don’t expectorate). Between acute attacks, breath sounds may be normal.

The intensity of breath sounds in symptomatic asthma is typically reduced. A prolonged phase of forced expiration is typical of airflow obstruction. Evidence of lung hyperinflation (use of accessory muscles, for example) is particularly common in children. Acute attacks may be accompanied by tachycardia, tachypnea, and diaphoresis. In severe attacks, the patient may be unable to speak more than a few words without pausing for breath. Cyanosis (a bluish or purplish tinge to the skin and mucous membranes), confusion, and lethargy indicate the onset of respiratory failure.

TREATMENT

Treatment of acute asthma aims to decrease inflammation, coughing, wheezing, and shortness of breath, bronchial airway swelling, and increase pulmonary ventilation. After an acute episode, treatment focuses on avoiding or removing precipitating factors, such as environmental allergens or irritants.

If asthma is caused by a particular virus, bacterium, toxin, or other foreign substance, it may be treated by desensitizing the patient through a series of injections of limited amounts of the antigen causing the attack. The aim is to curb the patient’s immune response to the antigen.

If you have asthma and you enjoy outside activities that take you to higher elevations or much, much higher, the possible danger has certainly crossed your mind. Well, the news isn’t all bad, though it is cautionary.

Asthma is a chronic lung condition, characterized by a difficulty with breathing. People with asthma have extra sensitive or hyper-responsive airways. During an asthma attack, their airways become irritated and react by narrowing and constructing, causing increased resistance to airflow, and obstructing the flow of the air passages to and from the lungs.

There’s no question, as an asthma sufferer you’re more likely to be affected by altitude sickness than if you didn’t have the disease. However, if you’re fit and healthy, with asthma that’s well controlled, you should have no problems coping. This is, of course, provided you ascend slowly and recognize and accept your limitations.

Altitude will generally have little effect on stable asthmatics.

If your asthma is so severe that your blood oxygen is low, then air travel can put you in danger of reducing your blood oxygen level even further. That, combined with the dry, cool conditions generally encountered at high altitudes, could trigger asthma symptoms. In addition, if your destination is a high altitude, a city such as Denver for example, and you’re unaccustomed to that altitude and have little opportunity to acclimatize, you may experience heightened symptoms. As always, discuss this with your doctor ahead of time.

Now, if you’re dealing with severe asthma and you’ve been using your bronchodilator three or more times a week over the previous year, high-altitude treks can also increase your risk of an asthma attack. As already mentioned, the dry, cool conditions generally encountered at higher altitudes tend to aggravate the disease. Climbing, in and of itself, can be a very strenuous exercise which may trigger exercise-induced asthma in some people.

Then there’s your inhaler to consider. In freezing conditions, pressurized inhalers may not work properly. So before using yours, first you’ll need to warm it up using the body heat from your hands.

The best thing to do is to discuss your trip with your doctor several weeks in advance of your departure. This will allow time to work out a personal asthma action plan for the trip. This might involve increasing your preventer treatment for several weeks before the trip to give your airways extra protection, or measuring peak flow while away to determine how altitude is affecting your lung function, or even simple things like ensuring that you have enough medication and backup medication.

High altitudes do not need to be avoided. Just make certain you take some basic precautions. Humid air is certainly better for keeping your airways moist. However, the effects of dry, cool air can be prevented by keeping your asthmatic condition under close control. And some asthma sufferers, particularly those whose asthma is triggered by house-dust mites may actually find their asthma improves at higher elevations, where the dust mites can’t survive.

So ask your doctor about any high-altitude travelling you have upcoming, heed his advice, and enjoy your trip!

There are forms of exercising that are better for those who have asthma.

Certain forms of exercise will cause more wheeziness or chest tightness than others.

For example, running outdoors not as good as swimming.

Indeed swimming is one of the best forms of exercise for people with asthma because the swimmer is surrounded by warm, moist air.

On the other hand if the air you breathe during exercise is cold and dry, then the asthma will be worse.

If it is warm and moist, as with swimming, then the asthma will be not be as bad.

This tells us why swimming causes less asthma attacks than running, or other forms of exercise.

However, asthma and associated allergies can be complex as some asthmatics suffer worsening symptoms from the fumes (chlorine) in swimming pools.

The amount of time you exercise important as it usually takes at least six minutes of continuous exercise to trigger an exercise-induced asthma attack, and exercising for less time than this may not be enough to trigger an attack.

For a few hours after you have had the exercise-induced asthma, repeating the same amount of exercise will no longer produce the same amount of asthma symptoms, or may even produce no asthma symptoms at all.

In this way some patients are able to avoid exercise-induced asthma either exercising with short bursts.

Therefore asthmatics are particularly suited to sports and exercise, which consist of short bursts of activity with periods of rest in between.

While long-distance or cross-country running would be a bad choice of sport because they are undertaken outside in cold air without short breaks others are possible including…

*Football or hockey, or similar sport, as they are played in brief bursts with short breaks and periods of rest in between.

*Swimming is an great form of exercise for anyone with asthma. The warm moist air in the swimming pool is less likely to trigger symptoms of asthma.

*Yoga is a another exercise for people with asthma as it relaxes the body and the mind, reducing stress, and often done indoors where the air is warm.

There is evidence that indicates that gradual exercise can make you less prone to exercise-induced asthma.

Accordingly this disease does not automatically prevent a sufferer from enjoying sport at any level.

There have been many Olympians, including medallists, who were asthmatic and suffered from exercise-induced asthma.

However having the needed medical advice, asthma management, treatment, as well as the proper coaching, training, and self-discipline that every Olympic athlete needs to have, the asthma problems were overcome.

There are steps to help you help you in reducing the severity or number of asthma attacks.

*Speak with your doctor and make sure that you are properly and safely using your asthma medications.

*Warming up and down to get your muscles ready as well as getting your lung ready.

*Be aware of the weather and environmental conditions.

*Stay fit. Aerobic exercise help’s to reduce the effects of asthma and recommended by doctors for good health.

One of the triggers of asthma is fatigue. Having strong lungs, a benefit of exercise, is allows you to avoid the fatigue that brings on asthma attacks.

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!

Some kinds of exercise cause problems for asthmatics. Activities like climbing and skiing have an additional problem. Not only are there the exercise problems, but the altitude itself can cause an additional challenge of its own.

It is possible that people with asthma are more likely to be affected by altitude sickness. But what is altitude sickness? And why should asthma sufferers be more likely to suffer from it?

Simply put, people who live at lower altitudes can become ill when they visit high areas. They can feel light-headed, suffer from headache, suffer from fatigue, insomnia and palpitations, or experience lack of appetite, diarrhoea and abdominal pain.

One of the most acute collections of symptoms is around breathing difficulties; liquid accumulates in the lungs.

Will altitude affect your asthma?

The conditions are high altitudes are often dry and cold, and these conditions tend to worsen or trigger asthma. If your asthma is triggered by cold conditions, you might find that high altitudes are a problem, as the air temperature usually decreases at higher altitudes.

Bear in mid, though, that fit, healthy people with well-controlled asthma should have no problems coping with high altitudes, provided that they go up slowly. Recognise and accept your limitations. Make sure you have all your medicines with you. You may need to adjust your dose, and to plan your intake before, through and after your activity.

But be careful. In freezing conditions, pressurized inhalers may not work properly. They should be warmed (e.g. in the hands) before use.

Take it easy

Climbing and skiing can be very strenuous exercise and may trigger exercise-induced asthma in some people.

Some kinds of asthma may be eased

If your asthma is triggered by house-dust mites, you may even find that your asthma improves. Surprised? Why should this be? Simply because the house-dust mite cannot survive at altitudes higher than ‘the snow line’.

Take time to acclimatize

People with asthma who fly directly into a place that is at high altitude will not have time to acclimatize and may experience problems. So talk to your doctor so that the altitude if you’re flying to a high-altitude destination several weeks before you leave. This will allow you time to work out a personal asthma action plan for the trip.

Your plan might involve increasing your preventer treatment for several weeks before the trip to give the airways extra protection. Or measuring peak flow while away to determine how altitude is affecting your lung function. Or even simple things like ensuring that you have enough medication and backup medication.

Take care when exercising

Make sure you feel right at any particular altitude before going higher. If you start feeling breathless, slow down. Drink plenty of water, and eat small snacks often to prevent altitude sickness. And, do tell your fellow climbers and skiers that you’re asthmatic.

Remember to take everything in stages, talk to your doctor and keep your medicines to hand, and you should have a better time this winter.

Lung cancer kills more women every year than breast cancer. In fact, lung Cancer is the 2nd leading cause of death among both men and women with statistics showing it is an increasing problem for women especially as they have a proven susceptibility to developing lung cancer.

However, lung cancer poses additional risks and issues for women, and these can be generalised in one major way, and that is to do with smoking.

About 90% of all lung cancer deaths among women are as a direct result of smoking or breathing in someone else’s second-hand smoke. (This is known as Passive smoking).

Even though research has proven that smoking cause a wide range of very serious health effects, 1 out of every 5 women in the U.S. and other western countries still smoke with this number rising with a disturbing regularity every year despite widespread advertising to show how dangerous it is.

Various research studies which have been completed indicate that women who are former smokers may still have a significantly elevated risk of developing lung cancer even 20 years after they have quit smoking. However it is only fair to say that once they do stop smoking, the overall risk of developing lung cancer does drop.

According to an article in the Journal of Clinical Oncology in 2005:

Female smokers are more likely than male smokers to develop lung cancer,

Women who have never smoked are more likely to develop lung cancer than men who have never smoked.

These differences are due to hormonal, hereditary, and metabolic differences between the sexes.

Female smokers are 13 times more likely to die of lung cancer than women who have never smoked, and female former smokers are 5 times as likely to die of lung cancer as women who have never smoked.

Women, even if they have never smoked, should be aware of their higher risks. Because of the elevated risks that smoking causes for lung cancer and a range of other serious diseases, female smokers in particular should think very carefully about quitting smoking as soon as possible, as even though their past history of smoking does make them more liable to developing lung cancer, at least the overall risk decreases once they quit.
