"Pollen grains are the tiny reproductive structures that move genetic material
between flower parts, individual flowers on the same plant or a nearby member
of the same species. They are typically lightweight structures easily carried
on wind currents or are sticky and picked up in clumps on the feathers of a
honeyeater or the fur of a fruit bat or possum.
Hay fever is when the human immune system overreacts to allergens in the air.
It is not only caused by pollen grains but fungal spores, non-flowering plant
spores, mites and even pet hair.
The classic symptoms of hay fever are sneezing, runny noses, red, itchy, and
watery eyes, swelling around the eyes and scratchy ears and throat.
The problem with pollen grains is when they land on the skin around our eyes,
in our nose and mouth, the proteins found in the wall of these tiny structures
leak out and are recognised as foreign by the body and trigger a reaction from
the immune system."
