If you suffer from seasonal allergies, they may seem like they come earlier every year. Well, it turns out it̵
A study conducted at the Utah School of Biological Sciences found that the change in climate – and higher temperatures in particular – has both worsened pollen levels and how long it stays that way.
To come to this conclusion, researchers studied pollen samples from 60 locations in the United States from 1990-2018. They found a 21% increase in fabric over time and that the season lasts longer too.
The pollen content matters because it activates the body’s immune system to fight against what it sees as a foreign entity. Your body then releases a chemical called histamine that causes allergy symptoms.
William Anderegg, the study’s lead investigator, links these changes to man-made climate change, which has caused a steady rise in temperature over the years. The group also looked at statistics from different climate models to find a relationship between fluctuating temperatures and the season.
They found that the longer height and the increase in pollen were directly related to warmer temperatures. The allergy season now starts on average 20 days earlier and lasts 10 days longer than it was 30 years ago.
So it is not your imagination that your allergies have gotten worse. There’s not much you can do if that pesky pollen just doesn’t get lost![Via Martha Stewart]
