Most allergic patients suffer rhinitis in certain periods during the year (seasonal rhinitis). They notice worsening of their symptoms when they get to open spaces (parks, gardens), particularly in windy days, becoming less symptomatic in rainy days or indoor.
Allergens often culprit are located outdoors: pollen from trees (olive tree, cypress), grasses, weeds (goosefoot, Russian thistle, Pellitory, mugwort) and mould spores (alternaria, cladosporium ).
In some locations pollen and moulds can behave as perennial allergens, lasting all year long (as pellitory in the mediterranean area).
The rhinitis can also be suffered in a continuous way (perennial rhinitis). Its causes are indoor inhaled allergens (domestic enviroment), as house dust mites, animal danders, mould or cockroaches. This patients experience worsening of the symptoms when they go inside the buildings, in wet places and with fabrics that ease dust accumulation (books, carpets, mattresses, etc).
