Pollen allergy
With a pollen allergy, it is common for you to get one or more of the following symptoms:
You have both a runny nose and a blocked nose.
You sneeze a lot.
You have an itchy nose.
You get red, itchy, watery eyes.
You may feel tired.
Pollen allergy can also affect the airways. You may have a whooping cough and shortness of breath, which usually gets worse with exertion.
The problems start during the pollen season. In spring, birch pollen is most common, and in summer, grass pollen is most common. In late summer, it can be common to experience discomfort with sensitivity to gray bee pollen.

According to data obtained by the National Museum of Natural History, low levels of alder and hazel pollen have been measured all the way up to Gävle. But the season for the earliest pollen producers, hazel and alder, is mainly felt in the southern parts of the country and low levels have been measured in Bräkne-Hoby, Gothenburg, Hässleholm, Kristianstad and Malmö, among others.
According to the national museum, there is also an increased risk of high concentrations of alder in southern Sweden, which is the next highest level on a three-point scale. However, there is a small risk for high levels of hazelnuts.
— Birch pollen doesn’t start until April. But if you are allergic to birch, you can also react to alder, says Didrik Vanhoenacker, on-call biologist at the National Museum of Natural History in Stockholm.
Usually, the pollen season starts in March. The reason why the pollen now comes already in February is the mild winter, reports P4 Blekinge.
— The first species of trees start pollen production as soon as the weather becomes milder for a few days. The male pendants that release pollen are already ready in autumn, but it is now when it gets warm for a few days in January and February that they can start releasing pollen.
As the temperature rises, the levels may rise.
— There is a risk of high levels in Skåne and Blekinge. But as spring comes, pollen from alder and hazel spreads further. But it depends on how the weather turns out, says Didrik Vanhoenacker, on-call biologist at the National Museum of Natural History.
