The body recognizes these things, which would be allergens, as harmful foreign objects, so it attacks them, just like it does with pathogens. that's why you get all kinds of inflammation. the body doesn't know that they're in fact harmless.

a hyper reaction of your immune system a particular allergen.
many people who are not exposed to particular allergens (including parasites, pollen, bed bugs, and pollutants) at a young age (think infant and toddler) will overreact when they're older.
it's good to get some exposure to bacteria and dust when you're young it makes your immune system used to it so that it doesn't freak out when you're older.

foreign invader "protein molecules" trigger allergic response. It is a protective reaction when the body recognizes a foreign invader invading. Body wants to protect us from these allergans.

after repeated exposure to something your body thinks it is a danger and it is an attempt to fight it off.
