I think there may be some confusion. Istanbul is not located in Russia, it's in Turkey. Here's the text about pollen allergies and pollen seasons in Istanbul, Turkey:
Pollen allergy is a common problem in Istanbul. It occurs when the body overreacts to pollen from trees, grasses, and weeds. Symptoms include sneezing, itching, and congestion.
In Istanbul, pollen season starts in February with tree pollen. It lasts until May, with peaks in March and April. This is the worst time for allergy sufferers.
From May to July, grass pollen is the problem. This pollen is lighter and can travel longer distances, spreading the allergy misery. It's essential to stay informed about pollen counts.
The good news is that pollen counts decline in autumn and winter. During these seasons, allergy symptoms often disappear. Still, it's crucial to take precautions during peak pollen seasons.
When pollen counts are high, we suggest doing these things to help with allergies, especially on windy days when pollen is flying around.
