Allergies have no Purpose

Rather you believe in a god or in evolution the fact remains, allergies have no beneficial traits. There are many types of allergies, but I'm going to concentrate on allergies to airborne particles that cause your head to swell up like watermelon and your sinuses to produce enough mucus to fill a sink 2-3 times a day. Since these symptoms are very similar to a "common cold" a lot of people incorrectly assume they've caught a bug. The truth is that many times these symptoms are not produced by a virus at all.

Instead when foreign particles enter as you breath in, the mucus that your sinus system creates traps them to prevent them from traveling to your lungs. That part functions as designed. It's not until the sinus system decides that the current level of mucus production is not enough to handle the intake of foreign particles that you experience the cold-like symptoms. Its then that your nose overflows with goo, you become unable to breath through your nose at all, and it feels like someone has managed to squeeze a cantaloupe up your nose to put enough pressure on your brain that your just sure your eyes are gonna pop out. So why do some peoples sinuses over react more to certain particles than others? Why are some people seemingly not affected at all? The short answer is that scientist aren't sure. So for now we will just have to live with them, and continue treating the symptoms like we always have. For allergy victims, well... we just have to hope someone finds a cure to save us from our seasonal suffering in the near future.
