Birch trees are going to be a big worry for allergy sufferers in the coming days. The risk of allergy is high to very high across the country.
It is a spring in birch trees that the last bulletin of National Aerobiological Surveillance Network (RNSA) published this Friday (and valid until April 14). This indicates that the majority of the territory will be under the domination of birch pollens.
Whether or not they are the most numerous pollens, it will be these who, apart from the Mediterranean rim and to the south of the Gironde, will be the instigators of a high to very high risk of allergy.
Another cocktail in the southwest
Southwest of this limit, the times change. The most allergic will have to face a mixture of pollens of plane tree, oak, but also birch! This cocktail may carry a medium to high risk of allergy, while in the east on the Mediterranean rim, the plane trees calm down and allow a little respite, but beware of the arrival of oak and black-footed pollens. .. The threats therefore give way to other threats over the weeks.
Finally, last risk for the addicts of the handkerchief at the moment, and not the least, the grasses. They already disseminate some pollen over a large part of the territory. And if the sunny days persist, the development of these herbs and their flowering will increase, announces the RNSA.
The network concludes that allergy sufferers must follow their treatment or consult a doctor to be able to take advantage of the beautiful weekend announced.
