In many aspects of life, you can over-expose yourself to something and build up a tolerance to it. It is apparently a good way to treat phobias, and the reason we need to lay off anti-biotics.
I think it’s totally unfair that allergies are the opposite of that. The more you expose yourself to something, the more aggravating it is.
I have a winter hat I made last year (it honestly took less than two hours, and I love it) out of some Lion Brand chunky yarn with a 25% wool content. Let’s preface this by saying that I’ve never been allergic to wool until recently. I have a 36+ year old wool sweater (yes, it’s older than me) that has never bothered me. My winter coat is wool, and there used to not be problems with that.
But, in the last… several months, I’ve noticed that wool makes me itchy. Well, the coat issue (a very small part of the neck is the only part unlined) is easily fixed with a scarf. The wool sweater can be combated with a turtleneck. But the hat? No solutions for that.
And the more I wear it, the more itchy it makes me. And a blotchy forehead. I’m working as fast as I can to knit a new one out of a non-wool yarn, but knitting aggravates my tendinitis, so there’s a limit to my speed.
I just think it’s totally unfair that I can’t build up a tolerance to what I’m allergic to, since the list seems to be growing all the time.
