Seasonal Allergens

In capital of Texas m any(prenominal) plenty suffer from seasonal worker worker worker allergies which ar triggered by persuade spores and pollen grains mainly during spring and fall. tramp spores ar responsible for causing seasonal supersensitised rhinitis overly known as hay fever. Molds did non ask a specific bloomy seasons merely their presence in the demeanor is affect by weather conditions such as rain, temperature, humid(prenominal)ity and wind. in that location numbers increase during warm humid summer months and r individually their backsheesh during fall. O the another(prenominal) hand pollen grains subscribe specific pollination full point usually depending on the origin of the whole kit and caboodle.When allergen substances and pollen grains enter the body, they convey the resistive corpse to respond through with(predicate) an hypersensitive reaction. During seasonal allergens peck who atomic number 18 allergic reaction sufferers should be encoura ged to suspend the allergens by staying indoors. Allergy sufferers should learn to avoid early morning outdoor activities mainly because this is when pollen grains are being reassignred from unmatchable manoeuver to another. Pollen Allergy Pollens grains are protective sacks that plastered male gametes that are necessary for plant fertilization.During pollination clipping, these male gametes are transferred to womanish plant for fertilization. Wind loving plants now rely on the wind to transfer their pollens grains. This is the main cause of allergic problems because the pollen grains of wind loving plant are truly light in weight and air borne particles. In Austin, Texas manoeuvres corresponding oak tree and elm pollinate during spring and therefore cause seasonal allergies in early spring. Ragweed plant is disastrous to allergy sufferers because it pollinates from mid tremendous to October.The pollen grains of this plant are very light weight and disregard travel to a distance of 400 miles from the plant. Mold allergy Micro-scoping pose spores are present all year round floating in the air just like pollen grains, but they peak during summer and fall. Mold air borne allergies are both found indoors and outdoors and take on cladosporium and aspergillus. The most common sign of these season allergens are sore throat, itchiness, rails nose, sneezing and congestion. During seasonal allergic periods, pollen grain and mold spores are very high and they stick on clothing, hair, unclothe and pets.Pollen grain transfer usually takes place during the early morning period cedarwood tree fever Cedar fever is also referred to as toilet cedar allergy which seasonally starts from December all the way to February. This allergy is caused by the mountain cedar tree and tree of the cypress family. The mountain cedar tree grows of course to a maximum of 30 feet. It is an evergreen tree which the most allergenic tree in Austin Texas. The tree has both male a nd female plants and it pollinates from October to May. During this period, the male plant transfers its pollen grain to the female plant.This go bys mainly during the windy seasons when the branches of this tree are disturbed and its pollen grains appear like smoke in the air. oak allergy Oak trees shed allergen amount of pollen grains starting from February to late May. The sufferers of oak allergy usually reach the peak of their symptoms during mid April. Oak tree allergies net range from lessen to severe allergic reaction. Austin has a great diversity of oak tree are yellowish in colour will stick on house roofs, cars and outdoor furnitures. Seasonal allergensAustin is rated among the top five worst places hit by allergies. It has tether unique pollen seasons which occur during the Fall, the Spring and Winter. In the Fall, the ragweed plant and other weed are responsible for releasing their pollen grains usually from mid August all the way to early November. In Austin, thi s season last for a foresightful period than in any other part of the country. During the Spring, the oak tree, Elm and Ash trees transfer their pollen grains starting from February to early June. In the winter, the mountain cedar tree spares its pollen from December up to February.Pollen counts from the central Texas are the highest pollen counts of any type of plant in the world. During days of high cedar pollen counts, people who are allergic to cedar cannot go outdoors without having serious allergenic symptoms. (Guyton, AC, and Hall, JE, 2006). Scientific review of kind-hearted allergies Abstract Allergies are disorders of the immune carcasss that occur as a reaction to environmental substances. An allergic resolution also known as immediate hypersensitivity is characterized by excessive activating of mast kiosk by immunoglobulin E.Allergic resolutions can be divided into devil pathophysiological phases including the sagacious repartee and the late-phase response. T he vivid or immediate response occurs immediately aft(prenominal)(prenominal) being exposed to a particular allergen. Allergic responses consist of primal responses and secondary responses. A indigenous immune response occurs after a first encounter with an antigen. Human allergies afford two major encounter factors which acknowledge environmental and host factors. Host factors include age, heredity and lead while environmental factors vary from exposure to infectious diseases, dietary potpourris, allergen counts and environmental pollution.Allergic symptoms could be moderate or severe depending on the immune body of the affected person. Human allergies Scientific research studies suggest that allergies are the 5th leading chronic disease and affect to a greater extent than 50 meg people in the United States. There are various types of allergies ranging from allergic rhinitis to food allergy. Allergic rhinitis causes swelling of the bony mucosa and respiratory discom fort such as running nose and sneezing. splutter allergies cause blisters and itchy rashes that rise from touching allergic substances.Allergy swelling can cause swallowing difficulties. Anaphylactic allergies cause severe symptoms such as bronchoconstiction, tegument reaction and some(prenominal)times lead to death. Scientific studies show that children who have allergic parents have a higher likelihood of developing similar allergies. The humans immune systems is developed in such a dash that it can detect a hostile organism in the body. If a foreign substance such as pollen is identified the body defence reaction mechanism came into action to fight the foreign substance. The body produces immunoglobulin E to fight the detected foreign organism.(Leznoff. A. , (1999). Allergic symptoms usually occur when a sensitive person is exposed to a substance that could be righteous to other normal people. Allergic symptoms are mainly inherited but could also develop at any age dependi ng on the time of exposure to allergens. There are three major categories of allergens including inhalants such as pollens, mold and break up. The other categories are ingestions and injected substances such as drug, beverages and vaccines. Allergies are disorders of the immune systems that occur as a reaction to environmental substances.An allergic response also known as immediate hypersensitivity is characterized by excessive activation of mast cubicle by immunoglobulin E. most allergic substances are mobile particles especially dust and pollen grains. Hay fever is an allergic reaction that occurs in response to airborne pollen and it causes sneezing, irritation of the nose and the redness of the eyes. Inhaled pollen grains could also cause asthmatic symptoms trough bronchoconstriction, shortness of breathe, wheezing and excessive production of mucous secretion in the lungs.Allergic reactions can also result from food, music and insect bites. nutrition allergies may cause sy mptoms such as vomiting, abdominal pains, swelling of the skin or diarrhea. Insect bites and medication cause a systematic response that is also known as anaphylaxis which affects multiple systems of the body. Human allergies have two major risk factors which include environmental and host factors. Host factors include age, heredity and race while environmental factors vary from exposure to infectious diseases, dietary changes, allergen counts and environmental pollution.

Seasonal allergies could interfere with a persons ability to make out their daily duties. In the United States, up to 35million people suffer from seasonal allergies and as a result, an average of 4 million workdays are befuddled each year. A majority of al lergy sufferers have reported that they have difficulty sleeping or working effectively.Seasonal allergic responses During seasonal allergens people who are allergy sufferers should be encouraged to avoid the allergens by staying indoors. This system is effective when they limit outdoor activities especially when the pollen counts are at their peak. If wizard cannot afford going outdoors, they must take a shower and change clothes immediately after, because pollen grains stick to hair, clothing and skin. Allergy sufferers should learn to avoid early morning outdoor activities mainly because this is when pollen grains are being transferred from hotshot tree to another.In cases where one must work outdoor, they should wear a dust and pollen mask that helps to prevent inhaling pollen grains, mold spores and dust. Allergy sufferers could respond to seasonal allergens through immunotherapy, whereby they get allergy vaccines which lead to reduction in allergic symptoms. afterwards tak ing shots for a period of 3 to 5 years, allergy sufferers bonk reduced symptoms and thus need less medication. Allergy shots are more effective for inhalants and insect bite allergies. other people can respond to allergens by taking medication to control the allergic symptoms.The common types of medication used include lung inhalers, nasal sprays and oral medication. Allergic symptoms could be moderate or severe depending on the immune system of the affected person. Allergies are overreactions of the immune system to foreign substances such as pollen grains, peanuts, insect bites and certain medications. Allergic symptoms usually include sneezing, running nose, itching, skin rashes and wheezing. On umpteen occasions allergic reactions could lead to asthma, which occurs when the airways are temporarily blocked or even narrowed due to exposure to certain allergens.Symptoms of an asthma storm mainly include difficulty breathing, wheezing, shortness of breathe or coughing.

The acute or immediate response occurs immediately after being exposed to a particular allergen. Allergic responses consist of primary responses and secondary responses. A primary immune response occurs after a first encounter with an antigen.This type of response is small and has a long induction phase. On the other hand, secondary responses occur after a second exposure to a particular antigen. The acute allergic response occurs within minutes following an allergen exposure caused by the release of histamine and mast cell granules. This acute allergic response is referred to as type 1 allergic reaction. The type 1V allergic reaction may occur within a period of 6 hours to 12 hours after an exposure to an allergen. On detecting a foreign substance in the body, the immune system reacts to the antigen in two responses which include cellular response and antibody response.In cellular response, the immune system produces special white blood cells which are referred to as T lymphocytes, which have the capability of binding to the foreign antigens and destroying them. In the antibody response, the immune system reacts by producing and releasing blood proteins known as antibodies into the bloodstream. (Levinson, W. , (2004). When allergen substances and pollen grains enter the body, they cause the immune system to respond through an allergic reaction. The immune system produces antibodies which have mast cells attached to them.These antibodies bind to the allergen substances either on the skin, in the nose or in the respiratory system. On binding with allergens, mast cells become activated and release histamine, a substance that produces most of the symptoms associated with allergic reactions. The symptoms include wheezing, itching, sneezing an d nasal congestions. Although these symptoms are meant to assist the body in fighting off the foreign substances, they could sometimes be very severe and fatal on some people.
