Alen blooms in parts of Norrland and warm weather entails a great risk of high levels of alpollen in Västerbotten and southern Norrbotten, according to pollenrapporten.se.
In Götaland, Svealand and around the central Norrland coast, there is an increased risk of high levels of willow and elm pollen, according to the latest forecast.
The risk of high levels of birch pollen is still low, but that season is approaching.
Problems with fatigue
About 25 percent of Sweden's population has problems with allergic rhinitis and fatigue and among pollen allergy sufferers it is very common, says Christer Janson, professor and chief physician in asthma and allergy at the University Hospital in Uppsala.
- This is something we are really looking at as allergy doctors.
If there is a fatigue problem, this is something that may require more intensive treatment, he says.
Fatigue may be due to people with allergic rhinitis sleeping worse than usual and therefore getting more tired during the day, says Janson.
- But there may be other reasons as well.
It can be an inflammation in the body that is triggered by the allergy and that contributes to this fatigue, he continues.
Good help
Anyone who has problems during the pollen season and feels that over-the-counter medicines do not help should, according to Janson, seek help.
- The most important thing is that you do not walk around and suffer unnecessarily, because there is good help to be had.
If the problems are mild, you can treat it yourself with over-the-counter medicines.
If you have more difficult problems, you should go and check it out, be treated and get advice from a doctor.
Anyone who has major problems with pollen allergy can get allergy vaccine in tablet form.
- It is about getting the body used to what you are allergic to, he says.
