Changeable weather ensures fluctuating pollen count!

From the Enns to the March, the weather will remain changeable and unstable in the coming days. This slightly cooler phase marks the end of the tree pollen season. The amount of pollen from herbaceous allergenic plants in the pollen spectrum is slowly increasing. Although the precipitation washes a lot of pollen out of the air and provides relief for pollen allergy sufferers, as soon as the sun comes out again, a rapid increase in exposure is to be expected.

Oak and walnut continue to dust, while beech is already fading. Their pollen contains allergens that are very similar to those of birch, alder and hazel. Due to cross-reactions, oak pollen can affect people who are sensitized to birch plants.

For allergy sufferers who are sensitized to olive trees, the currently flowering lilac is of interest. As it is insect-pollinated, relevant pollen counts are only to be expected in the immediate vicinity of this ornamental shrub.

Note: At the moment, a yellowish film can be found on the surface of many lilacs. This is pollen from conifers such as spruce, pine and fir trees, which is often deposited as yellow precipitation on car roofs or window sills. From an allergological point of view, it is not a cause for concern.

In the Weinviertel region, along the Danube and in the Vienna Basin, smooth oats, grasses, panicle grasses and tussock grasses are currently in bloom. In meadows, dock and plantain can cause additional problems.

Although rapeseed has already reached the peak of its flowering period, allergy sufferers who are sensitized to cruciferous plants should continue to avoid the vicinity of these fields in order to prevent possible symptoms.

Other types of pollen in the ambient air: spruce, pine, elderberry, mulberry, rose, horse chestnut, sour grasses and cypress. These are of minor allergological importance.
