Some urban tree species cause an inordinate amount of asthma and allergy problems, while other tree species cause little or no health problems. A large part of the problem is that the arborists and landscape professionals, who plant these trees, often dont know the difference.
The type of trees (and shrubs) used in modern city landscapes has changed dramatically in the past three decades. In the past, the majority of street trees used were perfect-flowered, insect-pollinated trees, such as the once so common American elm tree.
Today though, many of the most widely used city trees are wind-pollinated species. Most of these species are unisexually flowered (dioecious and/or monoecious) and further compounding the problem, thousands of popular cultivars sold today are touted to be seedless, low-maintenance, pod-free or litter-free.
These fruitless, seedless trees are male plants, all male, and male trees produce prodigious amounts of allergenic pollen. Female trees produce NO pollen what so ever.
In dioecious-flowered trees such as most ash, willow and poplars, it is easy to propagate male only trees because they are separate-sexed. Monoecious trees, which in Nature always have both sexes (male and female flowers) on the same tree, also usually produce abundant pollen. It is possible to have all-male trees from the monoecious species. On many species the sexes will be born on separate branches, such as on a Honey Locust tree. If you take cuttings, or budwood, only from the branches with male flowers, then, you’ll get an all-male tree. Lots of monoecious Acer spp. cultivars are male-only plants. In a somewhat different way, there are also numerous monoecious species where only the top or only the bottom will have either male or female flowers. For example, the bottom half of a mature Italian Cypress for example is all-male. Female
wood is found only at the top of the plant. Thus, scion wood taken from the bottom usually produces “seedless” plants.
The terms dioecious, and monoecious, are botanical terms, not horticultural terms. We could perhaps say that a manipulated, asexually propagated all-male cultivar, taken from a monoecious species, is now dioecious, but this is not quite correct. A proper dioecious tree is one that in Nature is separate-sexed. These modern engineered trees are never found in Nature.
Interestingly, the first reference in print I ever found to this single sexing-out with monoecious street trees, was in a USDA booklet, from 1982, called Genetic Improvement of Urban Street Trees.

How Bad Is Allergy Now?
In 1959 the official rate of allergy in the U.S. was between 2 to 5% of the public. By 1999 the official rate of allergy had increased to an incredible 38% of Americans. Asthma, which was once considered rare, is now the number one chronic childhood disease in the US.

Where are Allergies and Asthma the Worst?
The most common allergen of all is pollen and since there are so many more plants growing in the country than in the city, it would make sense then that there is more allergy and asthma in the countryside. Right? No, wrong! Allergies and asthma are far worse in the city than they are in the country.

Several things contribute to this:
1.Pavement makes a poor pollen trap. Pollen in the city often lands on pavement where wind can cause it to become airborne again. In naturally vegetated areas where there is much more vegetation, pollen often lands on and becomes stuck in grasses, shrubs and vines or in trees.
2.Cities have more air pollution, which weakens the immune system and lung function.
3.Stress, which is generally higher in cities, can contribute to both asthma and allergy development.
4.Increased carbon dioxide levels within cities causes pollen-forming plants to produce more pollen with each bloom cycle, and also often causes urban plants to bloom more often.
5.Pollen loads are actually far greater in cities because there is a sexual imbalance within the plant community. In the city there is a preponderance of male trees and shrubs, while in the rural areas there is almost always a complete balance of plant sexuality. The excess of male plants in the city results in an excess of pollen.
6.The very lack of female plant materials in the urban environment also is a prime factor in the epidemic of allergy and asthma. Female flowers carry an electrical negative (-) charge (the trees are grounded with their roots) and airborne pollen holds a positive (+) charge. The tree and the pollen are mutually attractive; thus a female plant becomes a very effective pollen trap for pollen of its own species. But with almost no female trees and shrubs in modern landscapes, most of the pollen remains airborne.

How to Improve Health and Air Quality through Tree Selection
Landscaping to reduce allergies, especially pollen allergies, is an idea that is coming into its own. In the past few years several books have been written on the subject and interest is growing rapidly.
With the addition of OPALS, (Ogren Plant-Allergy Scale) arborists now have a means to design allergy-free plantings. This scale ranks all landscape plant materials on a simple 1 to 10 allergy basis. Trees that produce zero pollen, e.g., female cultivars, usually rank the best number one. Trees that have abundant, highly allergenic pollen, especially those with very long bloom periods, are usually ranked the worst in the 9-10 range. There are many trees and shrubs, however, that fall somewhere in between. Using a list of over 100 factors, OPALS numerically ranks each species and then further ranks the individual cultivars. There are often dramatic allergy differences even between two species in the same genus.

How Are Plants Allergy-Ranked?
OPALS was developed based on the following considerations: What do plants that are well known to cause allergies have in common? and What do plants that are well known NOT to cause allergies have in common? With these two questions it was possible to build two opposing sets of medical-botanical-allergy criteria. One set is positive and one set is negative. Examples of negative criteria: tiny flowers, excerted stamens, small (less than 25 microns in diameter) sized pollen grains, extended bloom period. Examples of positive criteria: complete flowered, sticky, heavy pollen grains, presence of nectaries, brief bloom period.
There are now over a hundred criteria used to develop OPALS rankings. Individual landscapers, city arborists, the USDA and the American Lung Association have already use the scale to make better landscaping decisions.
Based on the plant-allergy scale it is now possible to state, for example, that Acer rubrum Red Sunset maple, is ranked number one and causes no allergies. By comparison, Autumn Spire, a male cultivar of red maple does cause allergies and is ranked number nine. Most Pine trees will rank at numbers 4 to 5 and will cause some allergy. Platanus species (sycamore) rank number eight, and cause quite a bit of allergy. A male Canary Island Palm, Phoenix canariensis, which is considered one of the worst at a ranking of 10, will produce an abundance of pollen that will cause severe allergic reactions to many living nearby.
Pollen dispersal rates have been measured since 1972 (Gilbert Raynor, NY meteorologist) and although many pollen grains travel far in the air, research shows that most often 99% of a tree’s pollen falls out and sticks within fifty feet of the tree. This means that the closer one is to the pollinating tree the greater the exposure. Thus, the job for arborists is to plant trees that will not expose everyone near them to allergenic pollen.

So, How Do You Tell the Boys from the Girls?
It isnt always that obvious by looking at a tree (especially a young tree) as to whether or not it is a pollen-free female or a pollen-producing male. But since so many city trees are now asexually produced cultivars, the sex is predetermined. In the book Allergy-Free Gardening, which is the result of 15 years of research on this subject, several thousand trees were individually sexed and allergy-ranked. In some cities, pollen control ordinances are already on the books, although most of these could be improved an updated. Albuquerque, New Mexico is particular interesting, since it has attempted to curb allergies by prohibiting the sale and planting of any male cultivars.
As the public grows more knowledgeable about allergy-free landscapes, municipal arborists and landscape specialists will want to be ahead of the curve. They will want to show their clients that they are well-informed on the subject. In the future, instead of planting high allergy-trees, they will need to plan and plant healthy urban landscapes.

What is the difference between God and a Doctor? God doesnt think that he is a doctor. How do you tell the difference between a Doctor and a banana? If the banana doesnt go rotten in 14 days then it isnt a doctor. According to your doctor asthma is incurable, or as your Doctor learned after 8 years in University envying the number of women chasing the quarterback, who your Doctor in a jealous and drunken rage referred to in his secret diary as a hairy Neanderthal, asthma is a chronic (permanent) inflammatory condition of the lungs. The medical schools and the big drug companies and the big corporate executives have pawned off this deadly myth for so long that now even they believe it.

20 million Americans suffer from asthma. Does this mean that we should lay the blame for asthma on our creator? Did God not know how to create a functioning lung? Are we just prototypes in Gods vast laboratory? Perhaps without inhalers all of the asthmatics would die off and then the human gene pool would be freed from this genetic defect and then future generations would evolve into a species with perfectly functioning bronchial tubes. In the interest of future generations perhaps you should throw out your puffer and just choke to death sacrificing your life for the common good. This may get you into heaven in case you forgot to put your $5 into the collection plate last Sunday. Did Jesus have asthma? Did Jesus ever cure an asthmatic? Did Jesus know that asthma was incurable? Did Jesus go to medical school? Did Jesus play football? Was Mary Magdalene a cheerleader for the Jerusalem University Keepahs?

The reasons that the environmental organizations are going nowhere are myriad. One of them is that the word environmental is a combination of the words enviro and mental. No one knows what the word enviro means which leaves us with the word mental. People just think that these people are mental. George Bushs father referred to them as the spotted owl crowd. His son George proclaimed that there is no evidence that global warming exists. Jesus referred to the leaders of his day as snakes, blind guides, leading us all into the fire. The United States which likes to think of itself as the role model for a world which thinks of the U.S. as the black sheep of the family is the highest per capita polluter in the world. The reason that pollution groups are going nowhere is because people dont understand the meaning of the word pollution. The world is like a giant Jonestown filled with people believing that poison cannot kill them because some Bible writers, scribes, and who Jesus referred to as snakes spewing their deadly poisonous lies into your Bibles (Matthew 23) wrote this baloney in your Bible 2,000 years ago beside The Earth does not move and it never will three times. If God wrote your Bible then not only can he not create a functioning lung but he is also very poor at astronomy. Your Bible has 2,000 pages of Gods Word and no cure for asthma? Perhaps if the George Bushes had paid a little less attention to their Holy Bibles and checked out the Greenpeace website a couple of times, Greenland, Antarctica and the Arctic would not now be melting into the worlds 1 ocean which will shortly cause the sea level to rise 50 feet leaving nothing left of the United States except the peaks of Vail, which will be prime beachfront property.

In the Holy Bible God commands the cutting away of the foreskin, not the foresight. An ounce of prevention is worth a pound of cure especially when there is no cure for asthma. The pollution, the particles of poison in the air which we breathe into our lungs, like deadly airborne cyanide, hemlock and snake venom gets into your lungs when you breathe the air, it inflames your lungs and you have asthma. If you want to get away with poisoning childrens lungs with deadly poison chemicals so that they cannot breathe then give your poison a name that no one understands, like a carcinogen, a cancer causing chemical coming out of the exhaust pipe of your car like a bullet which hits its target and then explodes 10 years later in your own lungs and then slowly eats you alive in an excruciating prolonged death. It was announced yesterday that in Beijing, the site of the next Olympics, where the smog is so bad that more car accidents are caused by low visibility than msg, over 100,000 Chinese people died last year from the indoor air pollution in their skyscrapers from the chemicals gassing off from their carpets, furniture, and poor ventilation. Who would want to open a window in Beijing even if the office buildings did have windows? The air in Beijing is so filled with poison gas that the 100 yard dash at the 2008 Olympics has been shortened to 10 yards. What is the big deal searching for a cure for Aids in Africa? If everyone remained a virgin and then only had sex with their spouse there would be no sexually transmitted diseases. Is this a secret being deliberately held from the African people? You cannot break the laws of nature but if you do it will break your back.

Mold is a fungus, a tiny airborne animal that can only be seen when magnified through the lens of a microscope. Some molds exist in nature and we breathe it in all the time in small amounts and our bodies can handle it. However in larger amounts, or in people with immune systems weakened by all of the poison we breathe in every day, these molds which we breathe in, that multiply in our lungs and digestive tracts, these molds cause allergic reactions, aka tightening of the airways, aka chronic asthma, chronic bronchitis and chronic emphysema leading to death. The end of chapter 14 of the Book of Leviticus recommends that in some cases when these molds get into the wooden walls and stones of your house, you must tear down your house and rebuild it.

Doctors, i.e. allopathic doctors will treat the symptoms of your asthma and not the causes. Allergists will diagnose you with mold allergies and inject you with mold for 5 years of useless and painful treatment. Respiratory specialists will give you cortisone inhalers which cause thrush, candida, yeast, mold, fungus in your throat which your bloodstream then carries to every organ in your body including your lungs thereby aggravating the problem and making the doctors and the drug companies rich. Jesus commanded that everyone sell all of their possessions and then give all of their money to the poor. Are there any Christian doctors? Are there any Christians?

Here is the good news. Go to your naturopathic doctor, your doctor of naturopathy. Take the best from what both traditional and naturopathic doctors have to offer. Actually naturopathic doctors should be called traditional doctors since they are the doctors who are using herbal remedies which have been used and are tried and true since before biblical times, which are recommended in the Bible. In the numerous cases of asthma which are caused by breathing in airborne mold, there is a herbal remedy which can cure it. Oil of oregano has been clinically proven to kill bacterial infections which penicillin cannot kill, viruses which nothing can kill, molds, yeast and fungus. Many drugs are synthetic preparations of herbal remedies, plant medicine put on earth by God to save your life. Oil of oregano with sage and cumin taken in capsules will kill off the mold, and remove the root cause of the asthma, tiny animals eating their way through your lungs like they eat through wood and stone no matter how much you clean the surface. Your bloodstream will take the Oregacyn capsules (oil of oregano, sage and cumin search oregacyn) which you can buy over the internet or in your health food store to every part of your body including your lungs and kill the mold and cure the asthma. It is also good to take non dairy acidophilus, the healthy bacteria in our bodies which beats back the mold, and NutriBiotic grapefruit seed extract tablets which also kill the fungus. Years ago Doctors accused the naturopaths of practicing voodoo medicine and the Government threatened to ban herbal remedies as being unsafe. (Some are unsafe. Check with your naturopath and your doctor and your health food stores to see which ones.) Today many drug stores look more like health food stores than drugstores. In the fight for power, control and money in medicine and in religion, it is always the patient who ends up the big loser. If the 200 countries on Earth decided to make World Peace they could do it overnight at the United Nations. Unfortunately your Holy Bibles and your religious leaders forbid it. Also, the weapons manufacturers own and are pulling the strings of the politicians, and they will never allow World Peace, until nuclear world war III causes the extinction of all life on earth forever in the near future, which will also put an end to asthma once and for all. Think of it as radiology theology coming to your rescue.

Recent studies have shown that babies born to mothers who were exposed to high levels of pollen in their last trimester of pregnancy have a much greater chance of developing asthma. One of the main keys with asthma prevention is avoidance.
When you have asthma the typical garden is not a very friendly place at all. There are mold spores to contend with and worst of all is the pollen. Typical gardens have pollen producing male trees and male shrubs and other plants that can provoke asthma attacks. Almost anyone with asthma will tell you that their asthma can be triggered by a good number of things, but pollen is often number one for causing an attack. Garden allergies are common, but they need not be. Allergies from gardening could be largely a thing of the past if were willing to make some simple changes.
In fall of 1999 in Richmond, Virginia the American Lung Association of Virginia (ALAV) built a new Breathe Easy office and headquarters. They had this entire large building constructed with the latest innovations in green construction and sustainable design. No construction materials were used that would off gas any harmful or toxic chemicals, no materials were used that would trigger asthma or allergies. Every attempt was made to build something that would be pleasant and healthy to work in. The people who work in this office now will tell you too, that they all notice what a great improvement it is. Their office is a healthy building.
The ALA decided it would make perfect sense to landscape their new healthy building (in some states these are now called Health Houses) with an allergy free landscape. OPALS (the plant/allergy 1-10 numerical ranking system) was used to select only those plant materials that were either very low pollen, low allergy, or that were totally pollen free, allergy free. In effect they created the first true asthma friendly garden in the US.
Health Houses in other states are now also adding pollen free landscapes to their green construction, green buildings. A new Health House is about to be built in Pennsylvania, and the PA Association of Landscapers and Nurserymen are helping to surround it with an asthma friendly landscape.
Schools too are getting into the clean air act, and in the city of Visalia, California, the Tulare County Asthma Coalition recently directed the asthma friendly landscaping of a newly built elementary school.
Twelve keys to building your own asthma friendly garden:
1.Plant lots of female trees and female shrubs. Not only will these not shed any pollen, they will also trap a good deal of pollen that may stay in from somewhere else. Think of these female plants as natures air cleaners.
2.Use only low pollen or no pollen lawns. There are types of lawns now that are pretty well pollen free and these are a big improvement over some of the older lawn varieties. In southern states, if you have a common Bermuda grass lawn, consider replacing it with a newer, more asthma friendly hybrid Bermuda grass. Princess 77 is a new Bermuda grass hybrid that can be planted from seed. It is next to pollen free, grows very low and tight, and is especially good looking.
3.With OPALS 1 is best, 10 is worst. Use only plants with rankings of 1-5. The more plants in your gardens that have rankings ranging from 1-3, the friendlier your place will be for anyone with allergies or asthma.
4.Remove any trees or shrubs with rankings over OPALS #7. The woody landscape plants with rankings of 8-10 are all sure-fire allergy triggering plants and you can live without them.
5.Replace any removed high pollen, asthma triggering plants with their opposite, female trees or female shrubs. Also good as replacements are perfect flowered plants that are known to be very low pollen producers. These will all have good (low) OPALS rankings.
6.Use only plants that are well adapted to your own area. If you can find natives that have low allergy rankings, consider using them. Look around your own neighborhood, and see for yourself, which kinds of plants seem to be flourishing there already. For almost every kind of plant used in landscaping, there is now a no or low pollen version of it, if you know what to look for.
7.Use a wide variety of plant materials; diversity is good. Biodiversity always makes sense. The more diverse our gardens are he fewer problems well have with insects and molds.
8.Avoid plants with strong fragrances or odors, as they can cause asthma. Dont plant jasmines or similar vines next to entrances or exits and certainly dont use them underneath bedroom windows.
9.For mulch, use rock or gravel instead of bark to cut down on toxic mold spores in the garden. Flat stones or pavers also make good, mold free mulching materials.
10.To further eliminate mold spores, encourage wild birds in your garden. Virtually all wild birds eat insects, and insect damage triggers outbreaks of mold. Even the tiny hummingbirds actually eat a large number of insects. Put up a hummingbird feeder!
11.Keep your plants healthy. This too will cut down on both pollen and mold. When it is hot and windy, do some irrigating. Fertilize everything in the garden spring and fall. If plants are crowding each other too much, thin them out. If tree branches overhead are putting your whole yard in deep shade, consider having the tree thinned to let in more light. Fresh air and light are the enemies of molds.
12.If a tree, shrub, vine or any other plant always looks sickly, looks dirty, or always attracts bugs, then shovel prune it. Dig it up and get rid of it. Replace it with something easier to grow. Dont get caught up in having to spray insecticides all the time, as they too can easily cause asthma and allergies.

Make your garden a fun, stress free zone. Be sure to have a few comfortable garden chairs to sit in, and a little table of some sort is always good too. Wind chimes, bird feeders, and birdbaths can add greatly to your enjoyment and cost little. A beautiful, pollen free, allergy free, asthma friendly garden can be just the place for healthy children, and a great place for anyone to relax and enjoy the great outdoors. For more advice on low allergen gardening, look up allergy free gardening on the Internet, or go to your local library and read some books on this new important subject.

What we plant often has a direct effect on our own health and the health of those near us. A pollen-producing male tree in our own yard will easily expose us to ten times more pollen than would a similar tree growing just down the block. This can be compared to second-hand smoke. It is possible to inhale some smoke from a person smoking a block or two away from you, but it is hardly the same as someone smoking right next to you. It is the same with plants. If your own yard is full of allergenic plants, then you will be exposed most.
Elementary school landscapes are frequently highly allergenic because all too often they have been landscaped with trees and shrubs that will not produce any seeds, seedpods or fruitwhich the children might want to toss at each other. What is over-looked is that these tidy choices are usually male cultivars (clones) and although they are litter-free, they are prodigious producers of allergenic pollen. I am now involved with a pollen-free landscape planting at a new elementary school in Tulare County, California. This work is being sponsored by their local asthma coalition and it is very encouraging to see preventative measures like this being taken. Children suffer greatly from allergies and asthma, and asthma is now the most common chronic childhood disease in the US.
Another fine example of low-pollen landscaping surrounds the new American Lung Association Regional Headquarters in Richmond, Virginia. With green construction principles a new Breathe Easy allergy-free office was constructed. The allergy-friendly landscape plant materials are predominantly female, and compliment the clean air building. Other Breathe Easy offices are also now using pollen free landscapes, as are numerous Heath Houses.
Twelve tips: Remember, the greater the exposure to pollen, the greater the incidence of pollen-triggered allergy and asthma.

1.Dont plant any male trees or shrubs. These are often sold as “seedless” or “fruitless” varieties but theyre males and they all produce large amounts of allergenic pollen.
2.Do plant female trees and shrubs. Even though these may be messier than males, they produce no pollen, and they actually trap and remove pollen from the air. There is also some very good all-female sod to use for pollen-free lawns. As an added bonus, these female lawns stay low and require less frequent mowing.
3.Plant disease-resistant varieties: mildew, rust, black spot and other plant diseases all reproduce by spores and these spores cause allergies. Disease resistant plants wont get infected as much and the air around them will be healthier.
4.Use only trees and shrubs well adapted for your own climate zone. Plants grown in the wrong zone will often fail to thrive. Because they are not healthy, they will be magnets for insects. Insect residue, “honeydew,” is a prime host for molds and molds produce allergenic mold spores. Often native plants will be the healthiest choices.
5.Be careful with the use of all insecticides, fungicides, and herbicides. Accidental exposure to all of these chemical pesticides has been shown to cause breakdowns in the immune system. Sometimes one single heavy exposure to a pesticide will result in sudden hypersensitivity to pollen, spores, and to other allergens. This is as true for pets as it is for their owners. Go organic as much as possible. Make and use compost!
6.Diversity is good. Dont plant too much of the same thing in your landscapes. Use a wide selection of plants. Lack of diversity often causes over-exposure. Use lots of variety in your gardens.
7.Wild birds are a big plus because they eat so many insects. Plant fruiting trees and shrubs to encourage more birds. Suet also attracts many insect-eating birds. Insect dander causes allergies and birds consume an incredible amount of aphids, whiteflies, scale, and other invertebrate pests.
8.Use pollen-free selections whenever possible. There are many hybrids with highly doubled flowers and in many cases these flowers lack any male, pollen parts. Formal double chrysanthemums, for example, usually have no pollen. Another example would be almost all of the erect tuberous begonias. These have complete female flowers, but their male flowers have nothing but petals, making them pollen-free.
9.If you simply must have some high-allergy potential plants in your yard, just because you love them, then watch where you plant them. Dont use any high-allergy plants near bedroom windows or next to patios, well-used walkways, or by front or back doors. Place the highest allergy plants as far away from the house as possible and downwind of the house too. Remember: the closer you are to the high-allergy tree or shrub, the greater is your exposure.
10.Know the exact cultivar name of a tree or shrub before you buy it. Dont buy any that are not clearly tagged with the correct cultivar (variety) name and the Latin, scientific name. Compare the exact name of the plant with its OPALS/TM allergy ranking. With this scale, 1 is least allergenic, and 10 is the most allergenic. Try to achieve a landscape that averages at OPALS #5, or below.
11.If you have a tree or hedge that has high allergy potential and dont want to remove it, consider keeping it heavily sheared so that it will flower less. Boxwood, for example, has allergenic flowers but if pruned hard each year, it will rarely bloom at all.
12.Get involved with your own citys tree and parks departments, and encourage them to stop planting any more wind-pollinated trees. There are thousands of fine choices of street trees that do not cause any allergies and we should be using these instead. Working together we can make a healthy difference, and well all breathe better for our efforts.

*Note, with the dioecious plants (separate-sexed) males cause pollen-allergy, and females because they are pollen free, do not. Examples of some of these dioecious plants are: red maple, silver maple, box elder, holly, willow, aspen, cottonwood, poplar, fringe tree, pepper tree, carob tree, Osage orange, mulberry, cedar, juniper, podocarpus, yews, ash, date palms, and even asparagus.

Over 17 million Americans have asthma. Boost your awareness with this brief introduction to the disease.
What is asthma?

Asthma is a chronic condition that affects both children and adults. It is characterized by inflammation of the lungs, causing an inability to breathe properly. Certain triggers cause changes in the lungs of an asthmatic; airways restrict and may also become filled with fluid, which can lead to wheezing, coughing, and shortness of breath. Asthma affects 5% to 10% of the worlds population, with the United States having record numbers of cases. Currently, more than 17 million Americans have been diagnosed with asthma, and asthma is one of the number one reasons for missed work and emergency room visits in the country. Asthma can be a serious, life threatening condition, but is manageable with proper medical care, medications, and education.

What are the symptoms of asthma?

The most common symptoms of asthma are coughing, wheezing, and shortness of breath, but these are not the only symptoms that asthma can cause. Rapid breathing, irritation of the nose and throat, frequent sinus infections, allergies, excessive thirst, chest tightness and pain, productive and non-productive persistent cough, allergies, difficulty breathing while exercising, and waking at night with a feeling of being suffocated are all symptoms and possible signs of asthma. An asthma attack is usually marked by beginning with a noisy wheeze experienced while exhaling and rapid breathing. Panic can increase the severity of an asthma attack, which is an unfortunate thing, as an asthma attack itself can cause one to panic. I have noticed during my own asthma attacks that I experience chills, tremors, and a cold, clammy perspiration before and after an attack, along with marked weakness in my limbs. It is important to remember that each persons symptoms may differ from those of others.

Who gets asthma?

There are many different criteria for determining who gets asthma. The two most at risk groups for developing severe asthma are the elderly, and the urban poor. In the United States, 6.1% of African-Americans develop severe asthma compared to 5% of Caucasians. Also, African-Americans are three times as likely to die from severe asthma as are Caucasians. Childhood asthma occurs most often in boys, but after puberty reports show that cases of asthma are diagnosed most often in young women. Women run a much greater risk of death from asthma than do men, and the numbers are increasing steadily, especially in elderly women. 90% of all asthma deaths in the United States occur in the elderly.

Workers in certain occupations, such as farmers, hair dressers, and those in the textile industry, are at greater risk of developing asthma. Some known workplace allergens that may cause asthma include polyurethane, paints, steel, electronics, western red cedar, oak, redwood, mahogany, metal salts, vegetable dusts, and certain red dyes, and people that work with these substances on a regular basis have a greater risk of developing asthma.

Lifestyle also plays a major role in deciding who gets asthma. Studies have shown that those who are obese run a far greater risk of developing the disease than do people who maintain their recommended weight. On the other side of the coin, highly trained athletes, such as long distance runners, bear an increased risk as well.

It is also believed that environment can be a risk factor for those who live in heavily polluted areas of the country, such as large cities, industrial areas, and those who live near congested roadways.

Heredity can also bear a part in risk factors. Asthma seems to run in families, and an asthmatic couple wishing to have children should discuss their own risks for passing on the disease with their doctors. Asthmatics with children should also be on the lookout for signs of the disease in their children, as it can become quite severe if allowed to progress unnoticed.

What can trigger asthma attacks?

There are many things that can trigger asthma attacks, and they are different for each individual. However, some of the more common triggers include primary and second-hand cigarette smoke, food and plant allergies, allergic reactions to insect bites and stings, certain chemicals such as chlorine and ammonia, certain medications such as aspirin and beta-blockers, exposure to extreme hot or cold air, extreme emotion, colds or respiratory infections, mildew and mold, dust, and intense exercise. In 40% to 90% of people with asthma, intense exercise will trigger coughing, wheezing, or shortness of breath.

It is important to note that strong emotion, such as anxiety, fear, or panic, can trigger asthma attacks. When suffering from an asthma attack, the victim should be kept as calm as possible to avoid compounding or prolonging the attack by becoming distressed or frightened. My most severe, life-threatening attack happened after a car accident, and if I had not had a compassionate individual on hand to calm me, my condition could have ended up very bad indeed.

What are the consequences of asthma?

Asthma can be a serious illness that results in death, but most fatalities that are caused by asthma are preventable by seeking proper treatment from a medical professional. All that aside, asthma is still a frightening and debilitating disease that carries a myriad of problems along with it. Sleeplessness is one common problem suffered by asthmatics. In fact, 40% of all asthmatics lose at least 11 days of work or school per year due to difficulties caused by sleeplessness or lack of quality sleep. Between 17% to 30% of all asthmatics also develop chronic sinusitis and continuous nasal drain.

How can asthma be treated?

There are many options when discussing the treatment of asthma. Bronchiodilators are one of the most common treatments prescribed, and may come in the form of liquid, pills, or inhalers, such as Albuterol. Steriods are also used in order to beef up lungs and make them stronger, thus more able to resist asthma flare-ups. Certain exercise regimes may be recommended in order to build lung capacity, as well as an education plan in order to avoid triggers which may cause asthma attacks. Before undergoing any treatment plan you should always consult with your personal physician.

* 1 out of every 7 children is affected by asthma.
* It is the second major reason for the hospitalization of the children up to age 9.
* Asthma has affected 1 out of every 12 adults.
* The death rate due to it is constantly rising in America, Africa and Latin countries.
* It has become one of the major reasons of absenteeism from school in the US.
* It leads to 2 million emergency room visits and amounts up to 5,000 deaths every year in the USA alone.

Asthma is a chronic disease, which directly affects your airways. The airways are the tubes carrying air in and out of your lungs. Asthma is caused by inflammation and subsequent constriction of your airway. The condition is characterized by an instantaneous reaction by the airways in response to various triggers or allergens and substances.

During an asthma attack, the airway gets inflamed and restricts the airflow to the lungs. It directly effects your breathing and leaves you short of breath. It makes you wheeze and you can experience chest tightness. During an asthma attack the production of mucus by airway cells increases and it further causes obstruction in the air flow through tubes. You can die due to the lack of oxygen, if the attack is severe and prolonged.

Asthma, if not treated and controlled, can cost you your life.

It is widely known disease, effecting millions of people, still there is no concrete evidence towards its cause. Studies have revealed that it is caused due to allergic reactions caused by the presence of certain antibodies or certain conditions. Some studies also reveal that it is caused due to obesity and weight related problems. Various triggers or allergic reactions are known to cause asthma in people. It might not be necessary that the same trigger causes an asthma attack in all people. There are numerous triggers, which can cause asthmatic attacks. Triggers can be categorized as allergens, irritants and other triggers. Among the common triggers which initiate asthma attacks are as follows:

Allergens Dust Pollen Mold Cockroaches Dust mites Animal dander Irritants Tobacco smoke Air pollution Strong odor Laughing Crying Others Workplace chemicals Common cold Infections Exertion Respiratory infection Flu

It is important for you to identify what triggers an asthma attack for you. It would help you greatly if, once recognized, you in stayed away from any known causes.

Like other diseases, asthma also presents symptoms that characterize its early, advancing and later stages. Some of the common symptoms include coughing, wheezing, shortness of breath and chest tightness.

The first stage — Early warning signs of Asthma

If you are in the early stages of an asthmatic event, you might experience some common symptoms. These common symptoms are characterized during the inception periods of the asthma episode. The symptoms include:-

*Frequent coughing during sleep in the night.
*Experiencing wheezing or coughing after exercising.
*Shortness of breath.
*Extreme exhaustion following exercise.
*Feeling tired and upset all the time.
*Experiencing a running nose, sore throat, headaches and sneezing frequently.

If you experience any of the above symptoms, you should immediately get yourself checked for asthma. The swifter you act, the more you will be able to control it.

The second stage – Advancement and worsening of Asthma

If you are not able to identify the initial symptoms of asthma, or if you ignore those symptoms, asthma could get even worse. The advancement of asthma starts affecting your daily activities and sleep. Some of the symptoms of worsening asthma include.

*Regular and undying cough.
*Frequent wheezing.
*Declined response to medications.
*Shortness of breath.
*Experiencing regular tightness in the chest. Asthma should be diagnosed immediately upon countering these symptoms or it could further advance into a severe stage causing damage to your body.

The final stage and its symptoms When asthma enters into its last stage it starts affecting you severely. It makes life difficult for you and can even cause the death. You would need immediate medical attention if you experience any of the symptoms listed below:

*Rapid breathing.
*Undying chest pain and pressure.
*Non-stop coughing.
*Sweaty and dull face.
*Blue fingernails and lips.
*Hampered talking.
*Retraction of neck and chest muscles.
*Frequent gasping for breath.
*Severe wheezing.

Asthma can only be controlled, not cured. So you must abide by proper medication and medical instructions. It is also important to stay free of any known triggers, which can cause an asthma attack.

You should visit your doctor immediately if you are concerned you may be suffering with asthma.

There are two types of treatments to reduce the symptoms and effects of an asthma attack using drugs that resemble two of our natural hormones.

These are adrenaline (epinephrine in the USA) and the steroid hydrocortisone and they form the basis for relievers that provide quick relief of symptoms and preventers for longer term care.

Most asthmatics use both preventers and relievers to form a medical regime to control the asthma.

These medicines are usually taken as inhalers so that they can be breathed in through the nose or mouth. Inhalers have advantages over other forms of medication because…

*The medicine is delivered where it is required in the lungs and so less of the medicine is needed.

*The medicine can be made to be biodegradable inside the body. After it has done its work in the lungs it can be broken down in the liver so there is little chance of harmful side effects.

*The medicine works more quickly.

Quick Relief Medicines

Drugs that resemble adrenaline (epinephrine) are known as ‘relievers’ and give rapid, short-term treatment and are used for when the asthmatic has worsening symptoms that if left untreated could lead to an asthma attack. The patient will feel the effects of these medicines within minutes but they only last a short time.

They are short-acting inhaled bronchodilators that work by relaxing the muscles that have tightened around the airways. They help open up the airways quickly and ease the patient’s breathing and are used only when needed. They are sometimes called ” rescue ” or ” relief ” medicines because they can stop an asthma attack very quickly and anyone who has asthma should always carry one of these inhalers in case of an attack.

Long-Term Medicines

These are called preventers and are taken every day, usually over long periods of time, to control chronic symptoms and to prevent asthma episodes or attacks. Medicines which resemble hydrocortisone slowly reduce the sensitivity the patient has towards irritants and allergens that would normally trigger an attack. It will take a few weeks to for them to show any improvement and once an attack starts they do nothing to alleviate it. Patients with persistent asthma need long-term control medicines.

Long-term medication includes:

* The most effective and long-term medication for asthma is an inhaled corticosteroid (or steroids for short) because his reduces the swelling of the airways that makes attacks more likely. This is the preferred treatment for controlling mild, moderate, and severe asthma and are safe when taken as prescribed by your doctor. There are many kinds of inhalers that require different techniques, and it is important to know how to use a inhaler in the correct way. In some cases, steroidal tablets or liquid are used for short periods of times in order to bring asthma under control.

* Long-acting beta-agonists are bronchodilators: these are not anti-inflammatory drugs but are used to help control moderate and severe asthma and to prevent night-time symptoms. Long-acting beta-agonists are taken together with inhaled corticosteroid medicine.

* Leukotriene modifiers (i.e., montelukast, zafirlukast, and zileuton) are long-term control medicines that used either on there own to treat mild cases asthma or used in tandem with inhaled corticosteroids for moderate or even severe asthma.

* Cromolyn and nedocromil are also long-term medicines used only to treat mild asthma.

* Theophylline is a long-termmedication used either on it’s own to treat mild asthma or along with inhaled corticosteroids to treat moderate asthma. People who take theophylline should have their blood levels checked to be sure the dose is correct.

Most asthmatics will need both a short-acting bronchodilator to use when symptoms worsen and long-term daily asthma medication to control the ongoing inflammation. Over time, a doctor needs to make changes to the asthma medication, increasing or decreasing doses and changing medication where required. The desire should bd to use the least amount of medicine necessary to control the asthma effectively.

Asthma Treatments with Relievers and Preventers

There two main types of medicines for the treatment of asthma:

*Quick Relief Medicines – also called relievers , and,

*Long-Term Medicines – also called preventers .

Quick Relief Medicines are fast acting, providing short-term treatment within minutes and are taken when the patient feels worsening asthma symptoms that can lead to an asthma attack.

Long-Term Control Medicines are taken daily, over long periods of time, to control the disease.

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.

Air Purifiers are all the rage now, everybody has them and everybody sells them. There are Ionic Air Purifiers, regular filter Purifiers and HEPA filter purifiers.

the Journal of the American Medical Association now suggests that the air pollution existing today in the US raises the risk of lung disease to a point where more than half of the US population is breathing unhealthy amounts of air pollution.

More than 50 million Americans seem to be suffering from allergies and more than 20 million battle asthma.

There is such a thing as Sick Building Syndrome, a worldwide phenomenon, when chemical substances used in office construction such as glue, insulating materials, cardboard, and fiberglass are steadily released into the atmosphere from electronic equipment, carpeting, furniture and fittings.

That is why the air inside buildings or residential structures may be many times more polluted than the air outside, according to the EPA.

Because of all these reasons Air Purifiers have become very important. The different types of air purifiers include mechanical purifiers, electronic air purifying systems, hybrid purifiers and gas phase purifiers. Most of these systems remove particles and harmful toxins from the indoor air.

The HEPA Filter is a High Efficiency Particulate Arrested Filter designed to remove 99.97% of all airborne pollutants 0.3 microns or larger from the air that passes through the filter ( including tobacco smoke, household dust and pollen).

There are also filtering technologies that operate by using ozonation. The most popular air purifier on the market today uses ozone. These purifiers actually produce ozone which is an irritant that can worsen asthma and decrease lung function.

The removal of particles from the air is what is measured when the efficiency rate is trying to be achieved.

The fraction of particles that is removed from the indoor air being measured is what determines the amount of efficiency an air purifier possesses.

Air cleaners using mechanical filters or electronic technology can perform particle removal. Mechanical home air purifiers are units that can draw the indoor air through a metal or fibrous filter that is designed to trap the particles.

Because filters have different size pores they are able to catch these particles. is able to catch these particles with its different sized pores. Different types of filters may be pleated , square, round, with different levels of efficiency.

Mechanical filters in general are very efficient in eliminating contaminants from the air as long as they are cleaned regularly. There are 3 diferent types of electronic purifiers:

Electrostatic purifiers pull air into a chamber and charge the particles electrically. The air is then let through wafers which are negative ion generators, give particles a charge and cause them to stick to the nearest solid object.

These purifiers are not as effective as the other electronic or mechanical purifiers because they do not eliminate particles but move them to another location.

Ionizers do the same thing but create ozone which in itself may be bad for your health. Ozone is a lung irritant produced by ion generators and some other electronic air cleaners and ozone generators.

While indirect ozone production is of concern, there is even greater concern with the direct, and purposeful introduction of a lung irritant into indoor air. There is no difference, despite some marketers’ claims, between ozone in smog outdoors and ozone produced by these devices. Repeated exposure to ozone pollution may cause permanent damage to the lungs.

Hybrid air cleaners use both mechanical filters and electronic technology in order to clean the air of particles. Ozone emissions may be present from the use of electrostatic air purifiers and negative ion generators. High levels of ozone may be harmful but cleaning the units as specified by the manufacturer may mitigate the possible bad effects of ozone to some extent.

Efficient Air Purifiers can cost anywhere from $500 to $1500 for a single room and a System to clean a whole house can easily run into the thousands of dollars.

Asthma (pronounced AZ-muh) is a chronic (long term) inflammatory disease that makes the bronchial airways particularly sensitive to irritants such as air pollution. It affects people of all ages causing breathing difficulties, shortness of breath and wheezing.

It is the leading chronic illness in children and is becoming increasingly common in the developed world and is now the most common chronic condition in the west.

Asthma sufferers are often described as “being allergic to modern life” as air pollution, processed foods and centrally heated, double-glazed houses (an ideal breeding ground for house dust mites) are thought to be major contributing factors.

Asthma can affect anyone, at any age, anywhere and about one in eight children and one in thirteen adults have asthma in the western world, and rates are on the increase.

Although there is no cure, it can be controlled or managed in most patients so that they have only minimal and infrequent symptoms and can live an active life.

Asthma attacks Asthma suffererers have extra sensitive or hyper-responsive airways that narrow due to a mixture of factors. The muscles around the air passages in the lungs can contract and at the same time the airway lining can become inflamed and swell. This results in narrowing the airways that can get further blocked by the secretion of excess mucus.

This is described as an asthma attack with symptoms including a feeling of tightness in the chest, a wheezing or whistling noise when breathing, coughing, breathlessness and difficulty breathing.

This feeling of fighting for every breath is one that some asthmatics describe as being a sensation similar to drowning.

Asthma attacks vary not only between patients but for the same patient from a slight tightness or breathlessness to a severe attack when the airways can close so much that not enough oxygen reaches the vital organs causing a life threatening medical emergency.

Managing the disease If you have asthma, then learning to self-manage it becomes an important part of your life. This may mean restricting exposure to things that trigger your attacks and taking medicines as directed by your doctor.

By controlling your asthma every day, you can prevent serious symptoms and take part in all normal activities and reduce the time lost at school or work.

Anyone with asthma should seek long term medical help as a doctor will not only prescribe the necessary medication but also monitor its effectiveness.

This is important as asthma is a chronic or long term illness and the effectiveness of medication can decrease over time and symptoms can return.

Drugs that resemble natural hormones help fight asthma. Adrenaline (epinephrine in the USA) based drugs act as relievers to provide almost instant relief from symptoms and hydrocortisone (a steroid) is the base for longer term drugs that try and reduce the sensitivity of an asthmatics airways, thereby reducing the chances of an attack.

Asthma can change progressively during the lifetime of a patient affecting them in very different ways.

Some patients suffer acute episodes but then enjoy long periods with few symptoms.

Others may have childhood asthma and then grow out of it only for it to return in later life.

At a Glance … What is Asthma All About?

* Asthma is a chronic inflammatory disease that makes airways (bronchial tubes) particularly sensitive to irritants such as pollution, and this is characterized by difficulty in breathing.

* If untreated, asthma can be a life-threatening disease.

* Asthma affects people of all ages and is the leading chronic illness of children.

* While asthma cannot be cured it can be controlled, reducing the frequency and severity of attacks.

* If you have asthma, managing it is an important part of your life as taking medicines and reducing contact with things that bother you can cut down time lost at work or school.
