Now this unpleasant and sometimes dangerous seasonal allergy called hay fever (pollen - pollen).Spasms in throat, watery eyes, nose and squishing constant sneezing - a consequence of the fact that the body's immune system begins to respond adequately to the pollen of various plants.This reaction is also called sensitization.
One of the most important signs of hay fever - a clear seasonal occurrence or worsening of symptoms, ie, when signs of illness appear in the same time of the year, and then disappear.The severity of the patient's condition, the intensity and duration of the sharpening depends on the concentration of pollen-allergen in the air (the higher the concentration - the greater the deterioration) and the sensitivity of the organism.
Each patient pollinosis inevitably have to become a botanist, to resist disease.
All plants are divided into two major groups: pol
In wind-pollinated plants for the most part large leaves and inconspicuous flowers.But roses and other colorful scented flowers are pollinated by insects, and therefore at high risk for patients with hay fever are not.
pollen itself - are complex germ cells.They include more than a dozen substances necessary for the reproduction of plants.That they so acutely responsive human body.
amount of pollen in the air (and thus the intensity of the attacks) depends on weather conditions: wind speed, air temperature, humidity.The more pollen, the stronger the attack.When it is hot and dry, dusting plant is an active, when it's cold and damp - less, but the pollination process is stretched.Significantly reduced the concentration of pollen in the air during and after the rain.
morning pollination activity is highest, and the day, in the evening, it is reduced and the minimum at night.If the patient moves to a place where no-allergen plants for 2-3 days attacks disappear completely.
Depending on flowering plants to which a person has an allergy, but rather on the period of pollination, hay fever may occur in the spring, summer or early autumn.
exacerbations season opens trees and shrubs.In March bloom birch, alder, hazel, in April it was the turn of poplar, elm, willow, willow, ash, maple, and in May pylyat lilac, oak, chestnut, beech, pine and some fruit trees.In June, its pollen hit deals linden.
From May through August is the turn of meadow grasses and cereals.In many parts of grains of pollen allergens is considered the number one.Allergies cause bluegrass, timothy, foxtail, bluegrass, ryegrass, feather grass, fescue, bluegrass, wheat, rye, barley and others.
autumn (September-October), make themselves known weeds: wormwood, hemp, ragweed (which pollen is extremely strong allergen), quinoa, chrysanthemum, thistle, burdock and other.However, among the weeds there are plants that are beginning to highlight the pollen before.So, Dandelion pollinated in May and nettles, sorrel and plantain pollination begin in June and end in the fall.
