Rain brings relief for pollen allergy sufferers!
After last week's warm, sunny weather and heavy pollen count, this week is starting off rainy with a slight cooling effect. The abundant rain will stay with us for a few days and wash the pollen out of the air. This means that people who are sensitized to pollen can prepare themselves for relief.
The flowering season for birch, beech and ash has now also come to an end at higher altitudes. Some green alder trees are already in bloom. Due to the wet weather in the coming days, hardly any pollen will be transported from the mountainous distribution area of the green alder to the lowlands.
The peak of the oak and walnut blossom is over. 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.
Lilac is important for allergy sufferers who are sensitized to olive trees. As it is pollinated by insects, it is harmful in the immediate vicinity or on contact.
In the meadow aspect, the grasses have now started to flower in the lowlands. Due to the rain, grass pollen will only have a low impact in the coming days. Dock and plantain are also in bloom.
In southern Styria, rapeseed is in bloom. Allergy sufferers should avoid being near these fields to prevent possible symptoms.
Other types of pollen in the surrounding air: pine, roses, horse chestnut, sour grasses and cypresses. These are of minor allergological importance.
