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.

Asthma has increased 300 percent in children in the past ten years. Research by WHO, in Germany, finds prostate cancer, breast cancer, and other cancers increasing due to mold-related problems.

Mold is the number one health problem with one in every three persons affected by mold and one in ten with a severe problem related to mold. These can range from the common cold, tonsillitis, otitis, sinusitis, bronchitis, asthma, and pneumonia, to cancer.

Check your home’s humidity levels; buy or borrow a hygrometer and watch the changes in R.H. that occur throughout a typical day in different rooms of the house and over the heating season. To inspect your home for mold growth, winter is the best time except for basements which should also be inspected in the summer. With a flashlight and some simple tools, go through the entire house, both inside and outside, searching for moisture damage and mold growth and their potential causes.

The Stachybotrus species of mold is dangerous; it will start growing in 80 percent humidity but, once established, can grow at 55 percent humidity. This mold can develop from the decay of building materials and is much harder to control. If more than ten square feet develop, it is advised that a professional clean it up. When you see a small speck of mold, that’s only part of the problem – the remainder being inside the walls.

‘Frog Page’ is a manual of the health of the environment and states that frogs are declining because of mold.

Some of the causes of mold are brush and trees within 30 feet of the building; venting the clothes drier inside the home; furniture against outside walls; old fill, causing building movement leading to cracks causing water ingress; concrete will wick up water even to several feet above ground; ventilation not directed outside, such as the kitchen range hood, which should be vented outside; plants and aquariums; drying clothing indoors; standing water, such as keeping cold water in the kitchen sink; hot tubs; using several gallons of water to wash floors.

‘Sick Building Syndrome’ is caused by moisture and mold growth. It migrates through foundations up from the soil. A dehumidifier is not the final answer as it only does the air and not the walls. What is required is a combination of ventilation, circulation, and heat.

Carpenter ants and termites will smell moisture from miles away and they only attack damaged wood.

Ventilation alone won’t help a crawl space. In the summer the vents bring in warm, moist air.

Mold forms on the coldest space. The only
way to deal with it is with heat. Wall heaters with fans are more efficient than baseboard heaters.

Pull furniture and store material away from exterior walls and off basement floors; leave closet doors ajar; leave bedroom doors open as much as possible; undercut doors; don’t block or deflect warm air registers; open drapes, blinds, and curtains; set the furnace fan to run continuously. This will use more electricity but can be offset by installing a two-speed energy-efficient motor; don’t cut off the heating supply or close off unused rooms.

Uninsulated or poorly insulated areas such as exterior corners or foundation walls, should be improved with additional insulation. Be sure to install an air-vapor barrier, usually polyethylene, on the room side of the insulation to prevent hidden condensation behind the insulation. Seal hidden opening into the attic, tighten the attic hatch, weatherstrip and caulk around windows and doors, gasket electrical outlets, caulk baseboards and seal the top of foundations. Using an air conditioner on muggy summer days also helps take out the moisture.

Humidifiers, dehumidifiers, air-conditioning units and filtration systems can be a source of mold growth if they are not regularly cleaned.

Key areas to check for moisture sources leading to condensation inside the home are roof leaks [especially at chimneys, flashings, skylights and eavestroughing]; wall leaks [especially at window and door flashing and sills]; foundation leaks [especially where the ground slopes toward the foundation]; and plumbing leaks [especially at toilet bases and under sink drains].

Check any fuel-burning equipment – furnaces, hot water heaters, boilers, fireplaces, and wood stoves – to ensure that they are venting properly. A blocked chimney could mean that combustion products, including large amounts of water vapor, are spilling into your house. Along with that moisture come dangerous combustion gasses, such as carbon monoxide, which cause deaths every year. Have heating equipment and venting systems checked by a trained service person.

If your moisture remedial work includes extensive air sealing, be sure that all fuel-burning equipment has an adequate supply of combustion air. High efficiency furnaces, for example, have their own air supplies and exhaust fans but conventional equipment may rely on house air for combustion and on ‘natural draft’ to move combustion products up the chimney flue. If starved for air or overpowered by an exhaust fan somewhere else in the house, such equipment can spill combustion gasses indoors. Examples of this include stains near the vent of a gas water heater, smoke entering the room from a wood-burning fireplace or stove, and pilot lights being blown out.

Mold growth often occurs in out-of-the-way areas like closets, corners, walls behind furniture and unused rooms. Increasing air circulation to these areas warms the cold surfaces and lowers local humidity levels.

To solve moisture problems, cover any exposed earth in a crawl space or basement with heavy polyethylene, sealed and weighted-down; slope soil away from foundations to keep basement walls and slab dry; patch any foundation leaks; don’t use humidifiers, unless humidity levels are below 30 percent R.H.; avoid drying firewood indoors; operate bathroom exhaust fans during a bath or shower; use your range hood exhaust when cooking; avoid steam-cleaning carpets in winter; clean mold from wood and gyproc with a 10 percent to 30 percent solution of hydrogen peroxide applied with a spray bottle. This is more effective than bleach and water.

If you use chlorine bleach, mix one part bleach with two parts water and a little detergent to clean nearby surfaces. Leave for 15 minutes and rinse well. Use gloves and protective glasses and good ventilation. Badly mildewed carpets, furnishings and books will probably need to be thrown out.

Molds are parasitic micro-organisms that appear as black, white or multi-colored stain or fuzz. In addition to causing asthma, they can cause other allergies and serious health problems. There are tens of thousand of varieties of molds and are difficult and expensive to identify, even for experts. Health officials recommend eliminating all molds from inside your home.

Most mold spores need condensation or damp materials to germinate and once are established, many colonies generate their own moisture and can continue to survive even under dry conditions. They also need mild temperatures and a source of food, such as house dust or drywall paper.

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.

Allergies are disorders of the immune system, which when a foreign substance that is normally harmless in most people causes an extreme reaction within the body. Contact can be with the skin, lungs, oesophagus, mouth, stomach and intestine and can cause a reaction to those organs plus the musculo-skeletal, genoto-urinary system, bowel, cardio-vascular, nose, eyes and brain. The substances that cause these reactions are called allergens and the person who suffers from this, is said to be allergic to the substance. When an allergen comes into contact with the body, the immune system believes it is under attack and produces antibodies called IgE to fight it. The antibodies trigger chemicals (the main one being histamine) to different organs of our body from mast cells which causes the symptoms of an allergic reaction.

The most common allergies are to dust mites, pollen, animal dander in household pets, insect bites, food and drink – the most common being milk, wheat, eggs, fish, soy, citrus fruits, seafood and peanuts, washing powder, cosmetics, toiletries, jewellery, mould and mould fungus, latex and rubber and certain drugs such as antibiotics and anesthetics.

Every individual has their own target organ that has more of an allergic reaction than the others organs. Whatever the substance that causes the reaction, the symptoms occurs in the weak target organs whether this is the same point of contact or not. The symptoms as a result from the allergic reaction will be dependant on the function of the afflicted organ and whether it is depressed or excited.

The main organs that are affected are the brain, eyes, ears, nose, lungs, heart, skin, bowel, genoto-urinary system and musculo-skeletal system.

The brain is the most sensitive of the body’s organs and is easily affected by allergies. Mild forms can be as simple as forgetfulness and severe forms can be as serious as dementia. ‘Woolly brain syndrome’ is a common symptom described by most people who suffer from allergies and this is why most people consider it normal. Other afflictions to the brain are anxiety, depression and panic attacks. The eyes can be affected by becoming watery, red and itchy and also afflicted by conjunctivitis. The mastoid glands in the ears can become affected producing pain and infection. When the nose is affected it can show symptoms such as hay fever, rhinitis, catarrh, blocked nose, sinus pain, sneezing and a running nose. The mouth and throat can be affected by swelling of the lips and tongue, sore throat and coughing. The heart can be affected which can cause hypertension, palpitations and irregular heartbeats. Asthma (wheezing and shortness of breath) and bronchitis can be cause by the lungs being affected and bowel can be affected with Crohn’s disease, colitis, diarrhea, bloating, abdominal pain and vomiting. The skin can be affected becoming itchy, inflamed and having a red rash as with eczema, dermatitis, psoriasis and urticaria. Urticaria (hives or nettle rash) can be caused by allergies to bee stings, medicines, animals and foods. The genoto-urinary system can be affected with PMT, cystitis, impotency and frigidity. Arthritis, Myalgia and fibrosis can affect the musculo-skeletal. The most extreme allergic reaction is anaphylaxis.

The target organ can change as the body changes, for instance, a child may have eczema as an infant which then changes to hay fever later in childhood which then can change again to migraine attacks in the teenage years which then can change again to arthritis in old age.

In the UK, 1 in 3 people will suffer from one or more type of allergy, 1 in 5 suffer from hay fever, 1 in 5 school children suffer from asthma and 6 million people have eczema.

Natural substances such as mould, spores, pollen, dust mites, animal dander and insects usually cause an allergic reaction in the upper respiratory systems. They cause redness, itching and fluid in the form of water and mucous and can affect the eyes, nose, sinuses, throat, lungs and bronchial tubes.

A person can be allergic to any food, wheat, milk, eggs, corn, yeast, coffee and chocolate are the most common. Food allergies mostly affect the nervous, respiratory, gastrointestinal and skin areas.

Allergic reaction can be caused by food additives and environmental chemicals such as chemical sprays, pesticides, hydrocarbons, tobacco smoke plus thousands of others.

Allergies to certain foods are associated with certain symptoms. For example, headaches are associated with chocolate and wheat, migraine headaches are associated with milk, eggs, nitrates, alcohol, cheese, chocolate, citrus fruit, nuts, wheat, tomatoes and MSG, eczema is associated with eggs, tomatoes and citrus fruits, hay fever is associated with milk, wheat, cola drinks, chocolate and sulfites, hives are associated with strawberries, nuts, pork, mangoes, tomatoes, eggs, chocolate and shellfish, asthma is associated with wheat and eggs, cerebral symptoms are associated with wheat, corn and Soya beans and childhood allergies are associated with fish, beef, rye, milk, wheat, eggs, peanuts, artificial colourings and flavourings and salicylates.

Other factors that can contribute to allergies are bad feeding habits in the baby’s first year of life, poor digestion, excess or repeated contact of a particular substance or food, low nutrients level, presents of candida albicans, parasites, worms or other bacteria, stress and environmental toxins.

To help eliminate or reduce the symptoms of allergies it is best to consume lots of still mineral water, brown or white rice, fruit juices except citrus fruit juices, lots of vegetables except corn and tomatoes, fish except shellfish, turkey and almonds, sunflower seeds and walnuts.

In conclusion, good nutritional health is vital to support our immune systems to help ward off allergic reactions to foods and environmental chemicals. Once a person knows they have an allergy, it is best to avoid that food or chemical, improve nutrition and exercise regime, combat stress and generally support the immune system. It is best not to ignore allergic reactions, as they can lead to further more serious illnesses.

Among all allergic and respiratory-related diseases, asthma allergy makes up the majority. Asthma allergy is perhaps one of the leading causes of respiratory illness among children and young adults although this condition may progress a lifetime.

While it is considered an allergy, asthma is so prevalent (especially among children) that it deserves to be addressed in its own chapter.

Proper care and health maintenance is essential to warding off the debilitating repercussions of exposure to irritants which could trigger all the symptoms underlying such disease.

What exactly is Asthma allergy?

Asthma allergy is a chronic lung disease characterized by difficulty of breathing, wheezing, coughing, and increased mucus production during recurrent attacks. These same symptoms can cause death in some cases depending on the severity of the amount of allergens involved and antihistamine molecules produced by the body enough to block the airways for the transportation of air to the lungs.

Around 7 to 10% of children experience the condition and current statistics shows an increasing number of sufferers. Asthma allergy does not seem to be an inherited disease since a family member, who apparently do not have relatives exhibiting the symptoms of the disease, can be infected anytime should he or she is exposed to environmental factors triggering the onset of the disease.

People with this medical condition have a very sensitive bronchial pathway. Presence of molecules or particles recognized by the body as foreign can set a huge allergic attack characteristic of the condition described above.

From a medical point of view, asthma is a type of allergy. Allergy is defined as a change in the body’s biological activity due to the presence of one or more types of allergens (substance promoting the symptoms of allergy.

According to the Asthma and Allergy Foundation of America, more than 50 million Americans are suffering from allergy and currently 20 million individuals, comprising the wide-range of America’s population experiences the symptoms of asthma.

Causes of Asthma allergies

The causes of asthma allergies are the same as for other allergies we have discussed. Causes can be in the form of dust, certain chemicals, scents, and various odors. Other trigger factors may be in the form of temperature. Cold or hot air can provoke allergic reactions to patients sensitive to them. In any case, allergic reactions are specific to individuals and not all individuals suffering from allergy responds universally to all types allergens.

Particularly interesting clients are the ones allergic to some forms of physical activity like exercise. In the same manner, emotional state is one factor for some individuals in order for the characteristic asthma symptoms to set in.

Among all these influential agents, smoke has been found to occupy the universally recognized trigger attacks for patients with asthma allergy especially for children. At least 8 out of 10 children are more prone to developing asthmatic conditions once exposed to these agents.

Perhaps, as society becomes industrialized and increased fume emissions accelerates, more and more people will develop symptoms characteristic of this disease.

Who Are at Risk?

Statistical data shows that asthma allergy is not a discriminating disease. It affects people of all ages, race, culture, color and gender.

Especially predisposed to developing such illness are people who are exposed to heavy car or industrial emissions and filthy surroundings. 10 to 12% of children averaging 18 years of age are the common target.

Additionally, individuals whose relatives have a history of such illness are more at risk in manifesting such condition in the future.

Latest Diagnostic Device and Treatments

Gone are the days when people die of symptoms and complications involved in asthmatic attacks. Due to the development of studies and research in asthma allergies and other forms of allergies, treatment and varying levels of diagnosis were introduced to properly treat the symptoms typical of asthma allergy.

But basically, one first hand “cure” or initial activity to be done in the management of asthma allergy is to avoid the source of the allergens to which the individual is allergic to.

For example, if the individual is allergic to dust, staying indoors may help reduce the probability of allergic occurrence. In any case, consulting a family doctor or an immunologist will provide you the most practical and wise information regarding dealing with individuals experiencing such condition and recommendations which will keep you from attacks you would rather stay away from.

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.

Whether you suffer from asthma, allergies or simply want to ensure the air in your bedroom is as clear as possible, there are several easy measures you can take to limit the amount of dust that collects in one of the most used rooms of your house. We spend more time breathing air in our bedroom than any other room, and shed more skin there too (unpleasant sounding, but true!) as we get changed in and out of work, casual clothes and pyjamas. The amount of dust in your bedroom can irritate existing allergies and asthma, or even just create an irritation without any prior allergy having existed. Opening the windows to let in the breeze can only clear your room for a short time, so setting up your room to be dust-free from the outset is the best way to go about cutting out that stuffy nose and horrible heavy-headed feeling in the morning.

There are many ways you can reduce the amount of dust in your bedroom, and you can of course use any or all of these methods, depending on how much work you are willing to do. Incidentally, when carrying out any amount of cleaning work in a dusty room, you may find it beneficial to wear a filter mask. They’re very cheap from any DIY or hardware store, and can save you a stuffed nose.

Carpets – The first major storage area of dust mites and their droppings is the carpet. If you can, replace carpeting with wooden floors (hardwood, tile or linoleum flooring can be obtained fairly cheaply at DIY stores for easy home-fitting). If this is not an option, you could consider treating your carpets with Tannic Acid, which kills the mites. It’s not as effective as removing the carpet however, can irritate some people’s allergies, and needs constant reapplication.

Furniture & Furnishings – Any flat surface in the bedroom is a perfect place for dust to gather. Try to limit such surfaces (floor to ceiling wardrobes is a good way to get round clothes storage) and get rid of all upholstery. Upholstered furniture simply adds another layer of fabric for mites to make their home, so ensure all surfaces and chairs are metal or wood, which can be scrubbed every now and then, and don’t store dust and mites. If you have any clothes that cannot as yet be stored in a closed drawer or wardrobe, store them in zippered plastic bags, and make sure shoes are off the floor. Avoid heavy curtains or Venetian blinds, use light fabrics or, ideally, window shades. The thicker the material the more space for dust mites to live and breed, and for dust to collect. Venetian blinds, obviously, provide multiple flat surfaces for dust to settle, so are not ideal either. When washing bedding, wash the curtains too.

Beds – One of the worst storage areas for dust mites and collected skin cells, mattresses are impossible to clean completely. If possible replace your regular bed with a waterbed, which is easily cleaned and provides no chance for dust mites to hide. Many stores will sell allergy-safe bedding covers and pillowcases, so use those or bedding with a Dacron content. When washing bedding, ensure you are washing at temperatures above 130 Degrees Fahrenheit. It goes without saying that it’s a good idea to avoid wool-blankets or other such comforters on the bed.

Pets – Of course if you already have animals you are not going to want to get rid of them, but just making sure they don’t get into the bedroom can make a world of difference. As mentioned before, you spend more hours in your bedroom than in any other room, so it’s worth excluding any fur-covered pets.

Cleaning – Try to clean the room completely and thoroughly every week, using a damp cloth on all smooth surfaces (including window sills and the tops of any high cupboards) to pick up dust rather than just kicking it into the air. Open windows to air the room while you wash bedding and furnishings, and vacuum any carpeting and upholstery you may have in the room.

Air Purifying – Using dehumidifier and air conditioners can help regulate high temperatures and moisture that can increase mite breeding. Only use air conditioners when absolutely necessary however, as they can dry the air so much as to be harsh on nasal passages.

When already firmly settled in a home, you can’t really move, but if you have a choice then it’s a good idea to avoid basement living. You can translate all these practices to the rest of the house too, with the living room being perhaps the next most important room to target.

For mild allergies, just putting some of these measures into practice can lead to quite some relief, and for serious asthma and allergy sufferers you can create a virtually dust-free room by doing everything talked about in this article, leading to better quality of life and often a reduced need for medications.
