Allergies are hell for those who suffer from them, and there are more and more of them. Unfortunately, global warming will only make things worse and prolong the period during which the pollen that causes them conjunctivitis and hay fever will be present in the air. The flowering period can simply be doubled …

Allergy season will start earlier and end later

Researchers from the University of Michigan in the city of Ann Arbor in the United States attempted to studydevelopment of allergiesFor the coming century is associated with the flowering of plants.
15 allergenic plants present across the Atlantic were analyzed, then computer-generated simulations to understand the effects of global warming on their flowering periods, And so on during the period during which their pollen is found in the air.

results published in the journal nature communication Tuesday, March 15, 2022, reveal the worst case scenario: Flowers will start earlier and end later(1). By 2100, pollen during this period in the air may just double in duration.

People with allergies, for whom hypersensitivity to pollen is already making life difficult, will always suffer more if a solution is not found by then.

always more pollen in the air

In addition to doubling the flowering period, the researchers’ simulations also allowed them to estimate an increase in the amount of pollen emitted: In some areas of the United States, the concentration of pollen in the air can triple.
However, as all allergy sufferers know, the more pollen there is, the greater the effects of allergies (hay fever, conjunctivitis, asthma, etc.).

what makes life impossible For about 30% of the world’s population who suffer from allergies worldwide, But even this is enough to pose a health economics problem. An increase in the duration and intensity of allergies may represent an additional cost that is still little studied by public health policies.
