Uncontrollable sneezing, red eyes and runny nose, the beginning of spring often rhymes with the first pollen of the year. With global warming and rising temperatures, allergy season may start much earlier and end much later, according to a recently published study. nature communication,
If you live on the Mediterranean arc, you may haveItching, Runny and uncontrollable sneezing for a few days. In this area, the Cupressaceae (redwoods, and juniper) come out of their winter dormancy and produce large amounts of pollen. In the west of France, ash is the pollen that saturates , From mid-January onwards, especially because of the mild temperatures recorded at the beginning of the year, started very early. a trend that is likely to continue or increase, ,
endless allergy season
From Department of Climate and Space Science and Engineering from the University of Michigan, working on a which predicts intensity and From Daily pollen between 2081 and 2100 – in a world where temperatures would rise by 4 to 6 °C. His analysis is only for the United States and 13 . is related to of plants accounted for 77% Respiratory system in the country. According to their results, From May be longer, but may be even more intense than what we are currently experiencing. Bad news for allergy sufferers!
Simulations indicate that spring pollen may appear 10 to 40 days earlier, and summer pollen andWill last for 15 additional days. With respect to the intensity of pollen excretion, all species Analyzed here, do not react in the same way. for example, And temperature decreases daily pollen production by 33% for alder, but increases by 50% for oak.
Nevertheless, the overall increase in pollen emissions in a year ranges from 16 to 40%. more CO. Who says2 Atmospheric, also called excess pollen.Created by the scientific community for many years. when Enter the researchers’ simulation, the peak in pollen production in recent years is still 2000% higher than that seen in the United States.
an important public health topic
Respiratory allergies due to pollen are a real public health problem. They are related to 20 to 25% of French people, adults and children alike. In sensitive people, respiratory allergies, such as tobacco or pollution, may promote the presence of, This chronic disease is characterized by From that causes episodes of shortness of breath, Of Chest and cough.
Its consequences kill about 2,000 people every year.Including one hundred children, adolescents or young adults. Public Health France estimates that more than 60,000 people are hospitalized. every year. In future years, respiratory allergies are likely to last longer and become more severe, increasing the risk of complications.
