Spring has arrived. The Mediterranean rim is exposed to a peak of allergic risk linked to cupressaceae. Elsewhere, alder promotes allergic rhinitis.
After a mild winter, the first flowers bloom. Pollen trees are also budding. These first signs of the arrival of spring are not going to make people happy. According to the National Allergy Surveillance Network (RNSA), France can expect a return of allergic rhinitis. Gentle, but very real.
The situation has already reached a red plateau in the southern departments of France. All the Mediterranean rim is experiencing a peak of pollen from cupressaceae (cypress, thuja, juniper). “Only the rain will be able to bring a lull”, warns the bulletin of March 18.
Elsewhere in the country, alder is quite active, but the risk is considered medium. The traditional grasses, they remain in small quantities. “It will be necessary to watch the willows and the charms which flowering has started as well as the birches which are in the process of preparing theirs”, recommends the RNSA. Unfortunately, it is too late to start desensitization, which allows you to escape the classic symptoms: allergic rhinitis (stuffy, runny nose, sneezing, itching), conjunctivitis (itchy red eyes), or even an asthma attack for the most sensitive. .
