Another heavy birch and first grass pollen load at the weekend!

The unusually warm temperatures for this time of year have caused the birch pollen count to drop dramatically and promise to be high again this weekend. In addition to the birch, the first grasses have already started to bloom in the lowlands. This means that in the thermally favorable
Regions are now experiencing a double burden of birch and local grasses.

In the inner city, plane trees and walnut trees are in full bloom, and the stresses that until recently were characterized by ash and hornbeam are now being caused by beech and oak. Cross-reactions between beech and oak can intensify the symptoms of birch pollen allergy sufferers.
Willows and maple are also in bloom, although their pollen is of little allergological significance.
In the mountains, the levels are still significantly lower, alder and hazel have already finished their pollen count.
What else can be found in our pollen traps? Spruce pollen and pollen from rush, ginkgo, sorrel and larch are hardly relevant for allergy sufferers.
The flowering season of conifers(pines, firs, spruces) has begun. Their pollen is in the air in large quantities and can cause yellow coatings (sulphur rain) on surfaces, but is not allergenic itself.
