The National Network of aerobiological monitoring (RNSA) expressed an allergic risk high to very high this week because of the grass pollen. People with allergies should not forget to take their medication.
Get out the handkerchiefs. With good weather also looming grass pollen and throughout France. The aerobiological National Monitoring Network (RNSA) is indeed a red alert card signifying a “very high risk” on virtually all the territory except in the South (orange, high risk) and Corsica (yellow, medium risk).
In his last allergo-pollen bulletin valid until June 16, it indicates that the grass pollens are the “winners throughout the country with a high to very high risk especially with the coming days will be sunny and warm and promote the release of pollen in the air. ” Station also pollen from chestnut that also make a first appearance on RNSA sensors with a very low risk of allergy.
The inhabitants of the south of France will also have to do with the oak pollen and olive although the allergy risk does not exceed the average level. Pine pollen pollination but still safe for allergy because they have an allergenic potential considered “low to negligible” by the RNSA. In contrast, the lime trees come into bloom, and those heavy pollen may be responsible for allergies nearby.
A risk difference is explained by the fact that not all pollen allergenic. Indeed, states that RNSA to cause allergy symptoms, it is essential that pollen grains arrive on the respiratory mucosa . “Only the wind-pollinated plants (trees and grasses) disseminate the pollen grains by the wind, while the insect-pollinated plants require the intervention of an insect for their pollination by transferring pollen from the male flower to flower original female receiving. ”
Its bulletin also that this is the best time to pull ragweed begins to grow. “Do not hesitate to snatch if only a few plants or to report on the platform Reporting Ambrosia if there are many.” Ragweed is indeed a wild plant whose pollen has a very high allergenicity, the main cause of the famous “hay fever”.
In this regard, the RNSA remember that it is important for allergy sufferers to follow their treatment and consult their physicians. Allergic rhinitis is characterized by sneezing fits and runny nose or mouth regularly, even a conjunctiva and itching in the nostrils. But in the most severe cases, it can also cause an asthma attack difficulty in breathing, accompanied by pulmonary wheezing and shortness of breath, with or without a cough.
According to the Association Asthma and Allergy , “we now know, studies have shown that over 20% of people with allergic rhinitis also have asthma and 80% of asthmatics also have rhinitis. The challenge is important. ” If it is difficult to avoid pollen, some simple precautions can reduce the risk of inhalation: not roll the windows open during pollen peaks, rinse your hair in the evening before bedtime or after a walk or aerate the slot early morning and late evening.
