What’s so bad about allergens that your body would rather kill you than let them enter?

Question

I know allergies are really common, but I don’t quite understand what’s so bad about pollen, peanuts, etc. that you body would rather shut down your airways entirely than let them enter. What exactly would happen if they did get in?

Your question assumes is that your body is expressing a preference. It is not.

If you understand allergies, think of it as a mutation that is not desirable.

Allergies are an abnormal excessive response to proteins that are attacked by your body.

There is no intention to harm the body.
