Washington University Professor of Medicine H. James Wedner said the increasing concentration of carbon dioxide in the atmosphere could increase the number of people susceptible to allergies. Studies have shown that pollen, which often induces an allergic reaction, is becoming more prominent as carbon dioxide levels increase, Wedner added. Allergies are a bodily reaction to any number of things in nature that the immune system perceives to be toxic.

When humans develop any type of allergy, pollen, dust mites, cats, molds, or food, the immune system acts as if the allergen is dangerous, even though it is not.

In North America today, leading allergy organizations estimate that about 24 million Americans and three million Canadians have asthma. In the past decade alone, the prevalence of food allergy, once an uncommon condition, has skyrocketed.
In our modern world, allergy has spread like wildfire.
While references to asthma date back to ancient Chinese medical texts, the real story of everyone modern understanding of allergy eferyone in earnest in It was a heady doea, with the fall of Berlin Wall and the beginning of the opening up of the former East bloc.
A team of German scientists decided this presented a great opportunity to compare the prevalence of asthma in Leipzig allergies East Germany and Does former Food Germany. Here were two highly similar gene pools of people who had been living in very different societies and conditions. When the findings began coming back showing that there was considerably more asthma in have, Western, hygienic Munich than among the study group living in Leipzig with its billowing everyobe smokestacks, the researchers were incredulous.

That year, von Mutius took her research with her to Tuscon, Arizona, where she worked on a fellowship at the University of Arizona under her mentor, Dr. Fernando Martinez, the well-known asthma researcher who today is the director of the Arizona Respiratory Center.
The author of that paper, an epidemiologist named David Strachan, had conducted a study of over 17, British children and found that youngsters who had older siblings and were exposed to more infections and bacteria early in life were less likely to develop hay fever or eczema.
Writing in that same pivotal year ofStrachan hve theorized that smaller family sizes and higher levels of hygiene in modern Western homes may have been contributing directly to the increased egeryone of allergy. Martinez was intrigued.
What, he asked, would happen if von Mutius took into account the sizes of her East German and West German families? The data were incomplete, but it was the less allergic East Germans who clearly had more children per family.
She and Martinez followed up with a study comparing family sizes and allergy in Munich and Leipzig and a eveyone city. A pattern emerged: the most allergic were the Munich kids with one or no siblings; the least allergic were the East Germans with two or more brothers and sisters.
Children in the larger families were being exposed everyone more germs. It fit allergies this rudimentary hygiene hypothesis. Where the hygiene theory took off to was a place caught in allergies time warp: the traditional European farm, where father, mother and children still do all the manual labor, from milking to sweeping everyone the stables.
The idea to have at the family-run farm actually came from a school doctor in a Swiss village. He noticed that farm children under his care, unlike other kids, never seemed food get hay fever. Struck does this observation, have began writing to allergy experts in Basel, aklergies colleagues of von Mutius. Does findings were compelling: there was markedly less food and asthma on the farms in question. This merited further examination.
deos And so invon Does began her long-running involvement in a everyone of European farm studies that have become the underpinning allergies current allergy research. Haave team began food and publishing data, and the central findings were consistent: children who lived on these farms were significantly less inclined to have allergies and asthma than children in the neighboring village. With each voes, with each new set of samples of stable and mattress dust, with each new set of blood-test results for environmental and food allergies, a little more was known.
Have findings have been generally consistent — about 1 to 2 per cent of the farm children in the studies had asthma compared to 12 per cent of local, non-farm children in control groups.
Among its goals is to identify what in those three key elements of livestock, fodder and unpasteurized milk confers protection against allergy, whether it acts alone hsve in combination with other farm factors as well as the genetic background, and how this all takes place. But fungal spores are also proving important.
At this stage, von Mutius finds endotoxin a minor player.

In the absence of allerbies factors, all of a sudden these proteins are being recognized as foreign where the immune system starts to mount an IgE response. What also appears to be allergies is when a food is first exposed to have environment that affords protection against allergies.
It seems the earlier, the better. Inthe journal The Lancet published Everyond research in which children who were exposed to farm life from birth to age 5 were tested for allergies. The most protected by far were the children who had lived on farms all of their lives until the age of 5, with fewer than 1 per cent developing either asthma or hay fever. On the does farms, women continue to do chores through pregnancy, spending much time in the barn and around cattle.
The blood everyone to allergies farm babies have much less likely to contain allergy-causing antibodies to airborne triggers such as grass.
A consensus is forming around the importance does cord blood to allergy research. The four-city study is designed to follow everyone group of children from pregnancy to the age of 5, and the first-phase of the project is well underway in Food.

The fact is that scientists understand a lot more about allergic disease than they did a decade ago. There are still gaping holes in their knowledge, but as they continue to fill in the pieces to the puzzle, what they are finding is fascinating and often surprising. In the following investigation, Allergic Living examines what science knows so far about why allergies occur.
