The grass pollen season has started 18 days earlier this year than last year, according to Asthma-Allergy Denmark. This is part of a worrying trend where pollen seasons not only start earlier but also become more intense and last longer. This is primarily due to climate change and an increase in atmospheric CO2, which affects plant growth conditions. A new analysis by Asthma-Allergy Denmark shows that the amount of grass pollen has increased by 19% over the last 40 years. Comparing the pollen seasons from 1981 to 2001 and from 2011 to 2020 also reveals that on average the season has been extended by 18 days.
Climate changes, including temperature increases, altered rainfall patterns, and wind conditions, provide better growth opportunities for trees and shrubs, resulting in higher pollen production. This has direct consequences for the portion of the population suffering from pollen allergies. According to the organization, up to a million Danes struggle with symptoms of pollen allergy each year. This trend is not only a challenge for allergy sufferers but also raises questions regarding public health and the need to adapt treatment options and prevention strategies in line with changing environmental conditions.
Asthma-Allergy Denmark calls for increased attention to this issue and works towards providing better information and assistance to the many affected Danes.
