With the arrival of spring, pollen season in Europe starts earlier and lasts longer, causing increased suffering for millions of people with allergies. As temperatures rise and days lengthen, the sneezing from winter colds transforms into sneezing caused by pollen.
Trees begin releasing pollen annually, starting with hazel and willow trees, followed by birch, ash, and oak trees, before grasses take over in the summer. Molecular particles in the air interact with the respiratory system and eyes, leading to an immune response that releases histamine, causing inflammations such as a runny nose and watery eyes.
Event Details
The start, duration, and intensity of the pollen season vary each year, depending on weather conditions and the physiological cycles of plants. Biologist Astha Tiwari from the Belgian Institute of Public Health confirmed that trees follow a natural cycle in pollen production, with strong years followed by weak years, indicating that pollen production requires significant energy.
It is estimated that about 40% of the European population suffers from pollen allergies, making it one of the most common allergens in the region. This percentage increases in urban areas due to factors such as pollution and lifestyle changes.
Background & Context
Over the past decade, it has been observed that pollen seasons have become longer, starting earlier and increasing in intensity. This change is likely linked to climate change, as rising temperatures contribute to trees and plants blooming faster, leading to an earlier start of the pollination period.
A study tracking pollen data from monitoring stations in Belgium, the Netherlands, and Luxembourg over 30 to 44 years found that most tree species showed an increase in annual pollen levels and peak values, as well as an earlier start to the pollen season.
Impact & Consequences
Research indicates that rising temperatures and increased concentrations of carbon dioxide in the atmosphere stimulate plant growth and increase pollen production, prolonging pollen seasons and raising their concentrations. As people's exposure to allergens increases, pollen-related allergies are also expected to rise.
Researchers from the University of East Anglia in England found that the number of people suffering from pollen allergies could double from 33 million to 77 million by 2050. Additionally, pollution and pollen create a vicious cycle, where each exacerbates the other, increasing individuals' sensitivity.
Regional Significance
In the Arab region, similar impacts may arise due to climate change and increased pollution. With growing awareness of pollen allergies, individuals should take preventive steps, such as avoiding outdoor activities during peak times and following tips to protect against pollen.
In conclusion, climate change and the challenges associated with pollen require greater awareness from individuals and communities, as these phenomena can affect quality of life and public health.
