What is hay fever
—
Contrary to what one might think, given the common name hay feverthis very widespread allergy does not cause an increase in temperature bodily and is not caused by hay. It’s not even the pollen itself that triggers the symptoms, but some proteins contained within it such as profilins and reserve proteins, and can also be influenced by factors not related to the environment such as emotional stress and excessive intake of alcoholic beverages.
To date they have been identified more than 20 types of hay feverunleashed by over 3,500 plants starting with birch, ash and le grasses more generally such as oats, caprinella, spelt, barley, millet and wheat.
