When the pollen fly?

When pollen (pollen) specific components of male flowers are called those crops, which are caused by insects or the wind (wind pollination) dissemination. For the allergist are primarily the so-called wind pollen clinically relevant: After contact with human mucous membrane contact, the pollen grains of different ingredients - such as specific lipids, proteins and sugar - free, the in affected allergic hypersensitivity reactions such as runny nose and watery eyes can result. These symptoms are seasonally limited, meaning that they usually die down ending with flowering again.
Depending on the region (vs. Southwest. North), the allergy-related flowering plants and therefore the pollen used at different times. The sea levels (vs. Mountains. Lowlands) and the direct surroundings (urban vs. Land) are relevant factors here. "It makes sense for the patient are therapeutic options for allergic rhinoconjunctivitis (hay fever) in a pollution-and pollen-poor region over a certain period of time. A so-called climate therapy calls for the natural relief of symptoms,. Is the goal, with appropriate measures to ensure sustainable rehabilitation and to prevent the emergence of other allergies, "recommends Dr. Vieluf, chief physician of the Department of Dermatology and Allergy Clinic at the Department of Borkum. The pollen count in the mountains or the sea is rather low and the pollen in the city until the evening is usually acute, while the reverse is true in a rural environment behaves. Generally applies that the plant starts flowering allergologically relevant to expel the so-called early flowering as early as the winter months. In spring, the pollen of hazel, willow, birch and alder, the most prominent allergens.Hazel (Corylus)
The hazel, a deciduous ornamental or Nutzbaumgewächs, are found mainly in regions with damp soil and in forests with thick bushes or hedges. She is a member of the Birch family, which begins in the winter month of February (and sometimes earlier) to engage in flowers. By April, the pollen can affect the hanging, male catkins with pollen allergies.Willow (Salix)
The botanists are about 450 known species of willow, the disclosure of the temperate zones to the Arctic reaches. But even for the tropics and the temperate climates of the south or the occurrence of willow subgenera is well documented. From this multitude of different pasture types about 30-40 species in Central Europe are common. Your Flowering is between March to May and usually reaches its peak in early April.Birch (Betula)
The birch tree, botanically the large family of Betulaceae (Birch family lat) belongs, is a so-called early bloomers, so that when pollen allergies can occur even in late March hypersensitivity reactions, which can sometimes until the end of the flowering phase (June) to continue. In our latitudes, about 40 different birch species are known, but also on the North American continent and Asia (primarily Japan), birches are common. Before going on a trip to these regions pollen allergies are well advised, if they inquire about the possible allergen load in the holiday destination and / or perform a timely SIT (Specific immunotherapy) can.Alder (Alnus)
The alder is a widespread genus of the birch family, in central Europe of the three species - green, gray and black alder - are located. In sheltered areas, the male catkins - like the hazel - even in winter (January) with maximum daily temperatures of about 10 ° C begin to bloom. Increased pollen flow is therefore already in late February and early March to be expected.Grass and herb pollen
The majority of hayfever sufferers react to grass pollen, flying mainly from May. Among them include cereals such as wheat and rye, and herb species such as plantain, sorrel and sagebrush.
From the end of July will have only isolated allergenic plant their flowering period, so clearly from this period, the pollen count, though not completely reduced. Is the basic principle is that, unlike 15 years ago today, the pollen be more intense and longer (until September) last.
