Pollen allergy is caused by pollen allergies and allergic manifestations of respiratory tract and eyes, is also a specific individual kind of allergic reaction to pollen, are common and frequently encountered disease of a serious danger to human health. In fact, pollen allergy is not difficult to understand, just remember that a few key words on it.

Keyword 1: part-4 large parts of the sensitive to pollen
Pollen generally around 30~50 μm in diameter, when they are dispersed in the air, very easy to be sucked into the respiratory tr

act. People with pollen allergies after inhalation of these pollen, produce an allergic reaction, it is pollen allergies. Pollen allergy causes the human body, was due to pollen-rich in proteins, some of these proteins is allergic to the major allergens. In General, the pollen allergy mainly for the following parts:
Special itching of the nose, continuous sneezing suddenly, emit large amounts of nose, the nose plug this is \"pollen rhinitis\".
Throat suddenly paroxysmal cough, breathing difficulty, with white foam samples of phlegm, even in the laryngeal stridor, asthma, this is the \"pollen asthma\".
Eye itching, eyelids swollen, pus or mucus secretions of water samples, this is the \"pollen conjunctivitis\".
Skin Erythema, papules appear, small scale, have a sense of itching or burning sensation, mostly in the wild after exposure to pollen skin caused by sun exposure.
Pollen allergy occurs in these human body parts is because of allergies in human body contains something called IgE immunoglobulin, pollen and combination of mast cells in the threshing, histamine releasing allergic media, and histamine can increase permeability of the capillaries of the body , causing increases in secretion of mucous glands, edema and pruritus. So people allergic to pollen appears itching of the eyes, nose, ear mucosa and skin, allergic rhinitis in patients characterized by sneezing, runny nose, such as allergy occurs on the bronchial Mucosa, there will be symptoms of asthma in patients.

Keyword 2: pollen allergy season--high season
Under normal circumstances, when pollen concentration in more than 100 tablets of/1000mm3, significant increase in pollen allergy sufferers. Pollen allergy is seasonal. Two pollen in the North, one is 3-5 in the spring months, the other is a 6-9 summer and autumn months. Spring pollens are mainly dominated by tree class, weaker of allergenicity; in summer and autumn of pollen is mainly dominated by vegetation classes, to Artemisia of As

teraceae, Sankoh grass sensitized the most. Therefore, generally in summer and autumn of pollen allergy in patients with more than the spring, and symptoms than the former.
Tips in different seasons, different pollen hold sway
Dominated by pollen of trees in the spring.
Dominated by gramineous crops in the summer.
Dominated by sunflower, hemp, Castor and other pollen in autumn.

Keyword 3: weather-and fear that pollen-like weather
Pollen-like weather: high temperatures, dry air, wind speed. Effect of climate change on the pollen of obvious. This year\'s class formation of pollen of trees in the spring and summer temperatures of the previous year (the high temperature and strong light, formation of pollen). The warm spring flowers. From this, spreading of pollen level has a great relationship with temperature, humidity, and wind speed, so at the peak spring pollen diffusion, especially in the windy days or days of sunny weather, children with sensitivity to pollen out sparingly, to parks and other places , to avoid the flowers and lush spots on flowers, take pictures as soon as possible and select the wind.
Pollen is afraid of the weather: rain, frost. When it rains, pollen in the air is completely taken away by rain, children allergic illness have improved markedly. In the fall, \"Frost\" pollen \"archenemy\", so the fall of \"Frost\", allergic children\'s days will get significantly better.

Keyword 4: level Green--Green is proportional to the degree and pollen allergy
Although countless trees and flowers in nature, but can cause specific physical allergy to pollen is only a small number of, mainly to take wind for pollination of flowers, and incidence of the disease and the degree of green, greening the more , the higher the incidence. Our number is 0.5%, the highest at around 5%; Japan reached 10%, because of its green cover

High rates of more pollen in the air.

Distinguish between pollen allergies and colds
Because about half of t

he patients with allergic rhinitis can develop asthma, 75% of patients with allergic rhinitis and asthma, so once during the pollen season sneezing, runny nose and other symptoms appear, be sure to identification and cold.
Hay fever cold
Seasonal with obvious seasonal without seasonal, but good in winter
Family history of hereditary, genetic family history-free, not genetic
Sneeze more and less severe
Tickle Tickle nose, eyes, ears are obvious early nasal itching, but do not clear
Snot nose, multiple water samples, nasal congestion, change multiple nasal obvious and persistent, cohesive go excretions nose
Systemic symptoms generally no systemic symptoms, some children with asthma with systemic symptoms of influenza can occur, such as fever, muscle pain
Infectious infectious flu-free infectious
A course to a few months, recurrent, protracted course of disease the common cold 1-3 day, influenza 5-10 days
From here we can see, the \"itch\" is the difference between colds and hay fever, one of the best approaches. Of course, in order to further confirmed, sometimes you want to do some special checks, such as checking the allergen; check the nose has eosinophilic granulocyte; BAS check; nasal mucosa provocation test for; condition of hospitals in the detection of serum specific IgE antibody levels. In short, only confirmed pollen allergy, to better symptomatic treatment.

Desensitization: the key to prevention and treatment
Desensitization therapy is to change the natural course of allergic diseases and effective control methods, desensitization of perennial and seasonal desensitization therapy. Pollen allergies are usually seasonal, and seasonal desensitization therapy can be used. Specific methods are: clear allergenic pollen types, and then in the pathogenesis of 3-4 months before the season began, pollen Antigen extract from the beginning of low concentration, low dose, increased subcutaneous injection, each level of desensitizati

on liquid concentration level increase 10 times.
The seasonal comes to to stop desensitization therapy, to next seasonal desensitization in the treatment of the same 3-4 months before.
General 4-5 successive year after seasons of desensitization treatment before, you can make the pollen allergy in the later seasons of onset of symptoms in patients with significantly reduce or even complete remission.
Pollen in the air one has regional, seasonal and diurnal variation characteristics, therefore, out of the environment is also a good method for prevention of allergy allergic:
1. season of allergenic pollen dispersed, midday and early afternoon to avoid outdoor activities.
2. in allergenic pollen one season should be living in a room with air conditioning.
3. conditions may live in the air after filtration of the room, air filters can be applied, often in the filtration of the air condition. Currently used, the filter method for high efficiency particle air filtration system, a mechanical micro-hole filter.
4. severe pollen allergy in patients with allergenic pollen seasons change place of residence may be considered to prevent disseminated.
5. avoid indoor gardening.
6. strengthening exercises, pay attention to the dietary balance.

The parents must read related links: why pollen allergy became Japan\'s \"national disease\"
Every spring, about one-fifth of Japanese would \"unanimously\" to suffer from are the play known as \"national disease\" pollen allergy--a walk out the door every day, will be sneezing constantly, at the same time tear would rush out, eye itching, severe headaches , really can be called slave!
Trees more than a total of more than 60 types of pollen is raised, but Japan people suffer from hay fever is also the source of pollen from Cedar. Originally, in the Japan domestic, half of the planted forests are pine forest – after the end of World War II, as Japan urban and street was burned out after the air raid and rebuild

their homes would need a lot of construction timber, pine has the characteristics of fast growth and good quality of wood and FIR was planted with trees of first choice. But when it came to in the late 1960 of the 20th century, has long lumber of fir forests began to generate large amounts of pollen, and making an increasing number of Japanese captivity the risk of Cedar pollen allergy, even new-born infants cannot escape.

Yogurt can be mitigated with allergic rhinitis
Japan recent studies show that if the lactic acid bacteria eat food every day, to a certain extent can relieve allergic rhinitis symptoms, including hay fever. Yogurt has this effect. Because milk through fermentation of yogurt, both to preserve the nutrients in milk, also adds active lactic acid bacteria, such as Bifidobacterium, lactobacillus acidophilus, Lactobacillus casei and other lactic acid bacteria. Active lactic acid bacteria are able to maintain balance of bacteria in human body to promote the growth of beneficial bacteria, inhibiting intestinal reproduction of putrefactive bacteria, prevent and hinder the body absorbs harmful decomposition of toxin, prevent infection, intestinal, enhance the body\'s resistance to easily adjust.
