According to forecasts until Thursday (21st), in the northern regions, on rainy days there will be a reduction in pollen levels in the air.
As for the Azores and Madeira archipelagos, “low levels of pollen in the atmosphere are expected”, indicates the bulletin.
According to SPAIC, the pollen present in the atmospheric air comes essentially from oak trees and nettle grass.
In the southern and inland regions of the country, according to the bulletin, levels of pollen, in the air, of plantain, grass and sorrel weeds are increasing.
The bulletin also predicts that, in the regions of Estremadura and Algarve, olive tree pollen will reach “important levels”, as well as that of parietaria in the region of Estremadura.
Birch pollen will be present in the air “in significant concentrations” in the northern regions, he adds.
According to SPAIC, outdoor activities should be avoided when pollen concentrations are high.
“Walking in the garden, mowing the lawn, camping or playing outdoor sports will increase your exposure to pollens and your risk for allergies,” he adds.
SPAIC also considers that medication will be the most effective way to combat allergy symptoms, advises the consultation of a specialist immunoallergology doctor for the correct diagnosis and prescription of the most appropriate medication and warns that prevention “may involve carrying out anti-allergic vaccines”.
The pollen bulletin publishes every week the levels of pollen in the atmosphere, collected by reading posts in various regions of the country.
