Why Do We Have Allergies?

It’s spring! Time for long walks with your dog, weekends spent outside, spring cleaning, and rolling the windows down in your car. Sounds wonderful, right? But what if you have allergies? If you’re like many Americans with allergies, the idea of spring brings dreaded thoughts of allergy symptoms like itchy eyes, a stuffy nose, mysterious rashes, and unexpected sneezes that rumble buildings.

So why do we have allergies? Simply put, our bodies (especially our immune systems) are designed to fight. Many generations ago before modern sanitation and medicine, there was an abundance of viruses, germs, and bugs for our bodies to fight off. Fast forward to present day, and we have evolved to be immune to many of those same bugs and germs. But, because our immune system is trained to fight, sometimes it diverts and starts looking for new opponents.

That’s where allergies come in. Our immune system starts recognizing tree and grass pollens among other things like molds and dust mites as targets, and begins to defend against them. The allergy symptoms that we experience are the effect of our immune system recognizing certain proteins as a threat, and responding to that threat.

Fortunately there are options to treating allergies and allergy symptoms. Head over to the Fight portion of the site to learn about the different options available for treating your allergies!
