The allergy symptoms caused by pollen still appear earlier

Allergy– According to the Finnish Association of Skin and Asthma, the inhabitants of the pollen will become a rush earlier as the climate warms.

This year, the pollen season started already in January.

“In southwestern Finland, a nutshell bloom already at the end of January, earlier than normal. This is already reminiscent of the situation in Central Europe, where the pollen season begins at the turn of the year, ”says a researcher of nature and environmental health Juha Jantunen Allergy, skin and asthma union.

According to pollen report at the University of Turku, south of Finland also became frequent pollen as early as January.

“In early spring, the long distance passing is to Finland with nuts and alder pollen. Leppä is also blooming in warm places in Uusimaa and southwestern Finland, ”says the docent of the Biodiversity Unit of the University of Turku at the University of Turku Annika Saarto.

Long -distance The amount depends on the air flows and what the flowering situation is in the area where the air flows.

The most significant cause of allergic symptoms will not bloom until later in the spring. Its first long -distance passes usually come in mid -April.

According to Jantunen, the flowering of birch has also been made about a week.

Not only does the pollen season start before, it will also last until the fall, says Jantunen.

This is due, among other things, to the fact that Finland will be transported to Finland in the late summer, which flowers in the late summer, later in the autumn.

Pollen In addition to extending, there is also more pollen than before.

“On the other hand, it is difficult to say it directly because pollen volumes vary from year to year. But if you look at averages, the quantities have increased, ”says Jantunen.

In the spring, for example, in southern and central Finland, the pollen of allergy trees is on average double compared to 1980s measurements, the allergy, skin and asthma union reports.

According to Jantunen, the continuous increase in the amount of carbon dioxide may also affect the flowering and pollen yield of plants.

“After all, the plant needs carbon dioxide to grow,” Jantunen recalls.

About allergy surveys According to Jantunen, it has also turned out that the pollen of some allergy plants is more allergic than before.

Allergenic, or the ability to trigger an allergic reaction, affect, among other things, air pollution, such as ozone, nitrogen dioxide and fine particles that are transported to the airways with pollen.

“In some respects, air pollution is probably declining, but it has been speculated that allergenicity is also affected by increasing carbon dioxide. It feels fertilize plants, and at the same time it can concentrate and increase the amount of allergenic material, ”says Jantunen.

This There are no exact forecasts of the number of pollen of the year, but according to Saarro, the birch pollen season is expected to be more strong last year.

“This year, birch blooms more abundantly than last year,” Saarto estimates.

Last year, according to Saarro, the birch pollen season was weak in much of the country.

Finland's most significant allergic groups are birches and hay, with 10-20 % of Finns in the pollen.
