Science has all sorts of explanations for stuff. Like electricity. Gravity. American Idol. And spring allergies.
A scientist wearing a lab coat will tell you that spring allergies are usually triggered by tiny grains of pollen filling the air, trying to fertilize other plants. All of that is well and good. Plants are nice. But when those pollen grains get up your nose, well… that’s when you’re in trouble.
Your immune system, which is like your own personal Department of Homeland Defense, thinks the pollen is some terrible invader, and sends out its armies of antibodies. When the antibodies attack the pollen, the battle releases nasty chemicals called histamines. And the histamines are what cause the running nose, sneezing, wheezing, coughing, and itchy eyes.
By the way, that illustration at the top of this post is in no way to be considered accurate or scientific. It just represents the way I feel these days!
