How do people start developing allergic reactions to things they weren’t previously allergic to?
In: Biology
There are lots of things people become allergic to with repeated exposure. A tiny bit once or twice is ok, our bodies can handle it. But if you are exposed to it too much, to often, your body can develop a reaction to it.
Case in point…. Nickle allergies, very common. Touch it a few times when you’re young, meh… Not much happens. But as you get repeatedly exposed to it, one day you start getting burning rashes when you come into contact with it. Your body’s ability to deal with the allergen has maxed out.
