Difficulty breathing, runny nose, eyes clogging - the cause of such seasonal exacerbations is allergy to pollen of plants.

Now this unpleasant, and sometimes dangerous seasonal allergic reaction is commonly referred to as pollen (pollen). Spasm in the throat, tearing eyes, squeezing the nose and constant sneezing - the consequence that the immune system of the body begins to inadequately react to pollen of different plants. This reaction is also called sensitization.

One of the most important signs of hay fever - a clear seasonal occurrence or exacerbation of symptoms, ie when the signs of the disease appear at one and the same time of year, and then disappear. The severity of the patient's condition, the intensity and duration of exacerbation depends on the concentration of pollen allergen in the air (the higher the concentration - the stronger the aggravation) and the sensitivity of the organism itself.

Flowering seasons

For each patient on a slaughterhouse involuntarily it is necessary to become a botanist in order to withstand the disease.

All plants are divided into two large groups: pollinated by insects and pollinated by wind, microscopic pollen which in huge quantities is carried by gusts of wind for dozens and even hundreds of kilometers, and the patient may feel attacks, although no nearby plants are observed. In general, allergy caused by windbreak plants - trees and cereals. However, among them there are those whose pollen does not cause allergies, such as pine.

In wind-pollinated plants, for the most part, large leaves and unpretentious flowers. But the roses and other bright, fragrant flowers are pollinated by insects and therefore they do not represent a big danger to sickle-sighted animals.

Saw itself is a complex germ cell. They contain more than twelve substances necessary for the reproduction of plants. It is on them that the human body reacts so acutely.

The amount of pollen in the air (and hence 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, planting occurs more actively when it is cold and damp - less, but the process of pollination is stretched. Significantly reduced pollen concentration in the air during and after rain.

In the morning, the activity of pollination is the highest, and the day before, it decreases and the minimum at night. If the patient moves to an area where there are no allergen plants, attacks in 2-3 days completely cease.

Trees, cereals, weeds…

Depending on the flowering of plants, which allergy is to a person, and more precisely from the period of their pollination, parotid gland may appear in the spring, summer or early autumn.

The season of exacerbations opens trees and shrubs. In March, birch, alder, hazel bloom bloom, in April the turn of poplar, honey, willow, willow, ash, maple leaves, and in May, pulverize lilac, oak, chestnut, beech, conifers and some fruit trees. In June, your spike blow is caused by linden.

From May to the end of August comes the turn of meadow grasses and cereal plants. In many regions, cereals are considered pollen allergen number one. Allergy is caused by subtlety, timophyte, foxtail, pyrite, tares, feather grass, bacon, pyrite, wheat, rye, barley and others.

In autumn (September-October) weeds are known for: weeds, hemp, ambrosia (pollen which is extremely strong allergen), loboda, chrysanthemum, thistle, burdock and others. However, among weeds there are plants that begin to emit pollen before. So, the dandelion is pollinated in May, and nettles, sorrel and plantain begin to pollinate in June, and end in autumn.
